NOTES TO CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

(unaudited)

1. Basis of Presentation and Significant Accounting Policies

Mindspeed Technologies, Inc. (Mindspeed or the Company) designs, develops and sells semiconductor solutions for communications applications in the wireline and wireless network infrastructure equipment, which includes broadband access networks (fixed and mobile), enterprise networks and metropolitan and WAN (fixed and mobile) networks.

Basis of Presentation– The consolidated condensed financial statements, prepared in accordance with generally accepted accounting principles (GAAP) in the United States of America, include the accounts of Mindspeed and each of its subsidiaries. All intercompany accounts and transactions among Mindspeed and its subsidiaries have been eliminated in consolidation. In the opinion of management, the accompanying consolidated condensed financial statements contain all adjustments, consisting of adjustments of a normal recurring nature, goodwill and asset impairments (Note 3) and restructuring charges (Note 9), necessary to present fairly the Company’s financial position, results of operations and cash flows in accordance with GAAP. The results of operations for interim periods are not necessarily indicative of the results that may be expected for a full year. These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 28, 2012.

Fiscal Periods– The Company’s interim fiscal quarters end on the thirteenth Friday of each quarter. The second quarter of fiscal 2013 and 2012 ended on March 29, 2013 and March 30, 2012, respectively.

Recent Accounting Standards– In February 2013, the FASB issued accounting guidance which requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component and to present significant amounts reclassified out of accumulated other comprehensive income by respective line items of net income if the amount reclassified is required to be reclassified to net income in its entirety. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional details about those amounts. The provisions of this guidance will be effective for the Company in its first quarter of fiscal 2014 and should be applied prospectively. The Company does not expect the adoption of this guidance to have a material impact on its consolidated condensed financial statements.

In October 2012, the FASB issued accounting guidance covering a wide range of Topics in the Accounting Standards Codification. These amendments include technical corrections and improvements to the Accounting Standards Codification and conforming amendments related to fair value measurements. The amendments in this update were effective for fiscal periods beginning after December 15, 2012. The adoption of this guidance did not have a material impact on the Company’s consolidated condensed financial statements.

Significant Accounting Policies –There were no significant changes to the Company’s significant accounting policies disclosed in its Annual Report on Form 10-K, filed on December 12, 2012, for the fiscal year ended September 28, 2012.

3. Impairment

Impairment of Definite-Lived and Indefinite-Lived Intangible Assets

During the second quarter of fiscal 2013, in conjunction with the evaluation of goodwill, as discussed below, the Company believed there were impairment triggering events and circumstances which warranted an evaluation of certain definite-lived and indefinite-lived intangible assets. These circumstances included lower revenue when compared with projected results, which led to weaker performance than the Company expected for the second quarter of fiscal 2013. Specifically, the carrying amounts of certain intellectual property licenses, photomasks and IPR&D within the Company’s wireless infrastructure reporting unit were determined not to be recoverable and to exceed their fair value. Accordingly, the Company impaired the entire carrying value of these intellectual property licenses and photomasks and recorded an impairment charge of $2.0 million on intellectual property licenses and $439,000 on photomasks in cost of goods sold on its unaudited consolidated condensed statements of operations.

The Company also recorded a $500,000 impairment charge on its IPR&D related to its wireless infrastructure reporting unit. The fair value of the IPR&D was based on a multi-period excess earnings technique of the income approach as of March 29, 2013. The significant unobservable inputs used in the valuation included revenue forecasts, gross margin assumptions, expected product cycle and a discount rate. The related product was projected to begin production shipments in fiscal 2014 and revenue was assumed to follow a normal five-year product cycle. Gross margin was assumed to remain constant during the five-year product cycle. The discount rate was a 2.0% premium to the wireless infrastructure’s WACC. The Company reviewed its other long-lived assets within its wireless infrastructure reporting unit and did not identify any other impairment.

Impairment of Goodwill

During the second quarter of fiscal 2013, the Company performed an interim evaluation of goodwill for its wireless infrastructure reporting unit as it believed there were impairment triggering circumstances which warranted an evaluation. These circumstances consisted of actual and projected decreases in net revenue due to slower than expected deployments of 3G small cell base stations, as compared to prior projections at the time of its acquisition of picoChip. Given the triggering circumstances, the Company performed step one of the impairment test for goodwill and determined that the fair value of the wireless infrastructure reporting unit, which was based on a combination of the income approach and market approach, was lower than the carrying value. Under the income approach, the fair value of the reporting unit was calculated based on the present value of estimated future net cash flows. Cash flows beyond the discrete forecast were estimated using a terminal value calculation, which incorporated historical and forecasted financial trends for the wireless infrastructure reporting unit and considered perpetual earnings growth rates for publicly traded peer companies.

15

Future cash flows were discounted to present value by incorporating appropriate present value techniques. Under the market approach, fair value was estimated based on market multiples of revenue and earnings or similar measures for comparable companies, when available.

Specifically, the income approach valuation included the following assumptions:

	March 29, 2013
Discount rate		21.0	%
Perpetual growth rate		4.0	%
Tax rate		29.3	%
Risk free rate		2.7	%
Peer company beta		1.32
Country risk adjustment for foreign operations		0.7	%

The failure of step one of the goodwill impairment test triggered a step two impairment analysis. The second step of the goodwill impairment test involved comparing the implied fair value of the reporting unit’s goodwill with the carrying value of that goodwill. The amount by which the carrying value of the goodwill exceeded its implied fair value was recognized as an impairment loss. As a result, the Company recorded a charge for the impairment of goodwill in the amount of $30.5 million during the second quarter of fiscal 2013 related to its wireless infrastructure reporting unit.

The Company will continue to evaluate its goodwill on an annual basis during its fourth fiscal quarter and whenever events or changes in such circumstances as significant adverse changes in business climate or operating results, changes in management strategy or further significant declines in the trading price of the Company’s common stock indicate that there may be a potential impairment.

4. Business Combination

On February 6, 2012, the Company completed the acquisition of picoChip, Inc. and its wholly owned subsidiaries (picoChip). picoChip is a supplier of integrated system-on-chip (SoC) solutions for small cell base stations. Pursuant to the terms of the acquisition agreement, all of picoChip’s outstanding shares were converted into the right to receive consideration consisting of cash and shares of the Company’s common stock.

The acquisition-date fair value of the consideration transferred totaled $64.3 million, which consisted of cash, common stock and contingent consideration. The cash consideration transferred upon the close of the acquisition was $20.5 million, of which, $14.3 million was deposited into an escrow account and a majority of the remaining $6.2 million was used to pay the remainder of picoChip’s outstanding debt.

The acquisition agreement contained provisions for additional earnout payments, contingent on the achievement of milestones relating to: (i) revenue associated with sales of certain picoChip products for the period beginning on the closing of the acquisition and ending on December 31, 2012; and (ii) product and business development milestones. The revenue milestone was not met and therefore the related liability was reduced to zero. The business development milestone was not achieved and therefore the earnout’s fair value was reduced to zero. Although one of the product development milestones was achieved, the second product development milestone was not achieved within the required timeframe and therefore the product development earnouts’ fair value was reduced from a total of $4.5 million to $2.5 million in the fourth quarter of fiscal 2012.

The Company has the right to offset the earnout payment with certain employee termination liabilities incurred subsequent to the close of the acquisition. For the three and six months ended March 29, 2013, the offsetting employee termination expenses were estimated to be $634,000, reducing the net contingent consideration liability from $2.5 million to $1.9 million.

The acquisition agreement stipulates that the purchase price is to be reduced if the actual net assets as defined in the agreement are determined to be less than the estimated net assets. As of March 29, 2013, the Company and the picoChip selling shareholders’ representative had not reached agreement on the amount of the actual net assets as of the acquisition date. On April 26, 2013, the Company and the selling shareholders’ representative entered into a settlement

16

agreement whereby the parties agreed to settle all outstanding obligations under the acquisition agreement, including escrow claims, earnout payments and the net asset adjustment on the purchase price paid by the Company in connection with the acquisition. In connection with the settlement, the Company was relieved of its $1.9 million net contingent consideration obligation, $3.5 million of payables owed to the escrow account related to a refundable research and development tax credit and received $1.0 million net in cash. This settlement will result in the recording of other income of $6.4 million during the third quarter of fiscal 2013. This settlement agreement releases the Company, the selling shareholders and the selling shareholders’ representative from all contingent consideration, claims and potential claims between the parties and the escrow account has been terminated.

5. Fair Value Measurements

ASC 820 defines fair value as the price that would be received from the sale of an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820 establishes a three-level hierarchy for disclosure that is based on the extent and level of judgment used to estimate the fair value of assets and liabilities.

• Level 1uses unadjusted quoted prices that are available in active markets for identical assets or liabilities. The Company’s Level 1 assets include investments in money market funds.

• Level 2uses inputs other than quoted prices included in Level 1 that are either directly or indirectly observable through correlation with market data. These include quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs to valuation models or other pricing methodologies that do not require significant judgment because the inputs used in the model, such as interest rates and volatility, can be corroborated by readily observable market data.

• Level 3uses one or more significant inputs that are unobservable and supported by little or no market activity, and reflect the use of significant management judgment. Level 3 assets and liabilities include those whose fair value measurements are determined using pricing models, discounted cash flow methodologies or similar valuation techniques and significant management judgment or estimation.

17

The following table represents financial assets and liabilities that the Company measured at fair value. The Company has classified these assets and liabilities in accordance with the fair value hierarchy set forth in ASC 820:

6. Stock-Based Compensation

Prior to February 12, 2013, the Company had three principal stock-based incentive plans that provided for the grant of stock options, unrestricted stock, restricted stock units and other stock-awards to employees and non-employee directors. On February 12, 2013, the Company’s stockholders approved an equity incentive plan that replaces the Company’s prior plans and provides for the grant of stock options, restricted stock, stock bonuses, restricted stock units, restricted stock awards, performance shares, performance units and other stock-awards to employees and non-employee directors. In addition to the equity incentive plan, inducement grants are occasionally made to new employees of the Company. The Company also provides an employee stock purchase plan for all eligible employees. The fair value of stock-based awards are estimated on the date of grant and recognized as an expense ratably over the requisite service period.

Total stock-based compensation	$	3,245	$	3,305	$	5,916	$	5,456

A management bonus accrual of $380,000 was recorded during the first quarter of fiscal 2013. The Company expected to pay 75.0% of the bonus in cash and 25.0% in equity awards. The equity award portion of the bonus, which was included in the selling, general and administrative line item above for the first quarter of fiscal 2013, was reversed during the second quarter of fiscal 2013 because performance targets of the Company were not expected to be achieved. The cash portion, which was recorded as a selling, general and administrative expense in the first quarter of fiscal 2013 was also reversed during the second quarter of fiscal 2013.

Stock option grant date fair value was estimated using the Black-Scholes pricing model with the following weighted-average assumptions:

7. Revolving Credit Facilities and Long-Term Debt

6.75% Convertible Senior Notes

On June 19, 2012, the Company sold $32.0 million in aggregate principal amount of its 6.75% Convertible Senior Notes due 2017, or the 6.75% convertible notes, for net proceeds of $30.6 million. Interest on the 6.75% convertible notes will be paid semi-annually in arrears in cash at a rate of 6.75% per year on the principal amount, accruing from June 19, 2012. The 6.75% convertible notes will mature on June 15, 2017, unless earlier repurchased, redeemed or converted. The 6.75% convertible notes are fully and unconditionally guaranteed on a senior, unsecured basis by certain of the Company’s subsidiaries.

The 6.75% convertible notes are convertible at an initial conversion rate of 256.4103 shares of the Company’s common stock per $1,000 principal amount of 6.75% convertible notes, subject to adjustment in certain circumstances. This is equivalent to an initial conversion price of $3.90 per share of common stock. Holders may convert the 6.75% convertible notes at any time prior to the close of business on the second scheduled trading day immediately preceding June 15, 2017. If the Company undergoes certain fundamental changes prior to maturity of the notes, including a change of control, sale of all or substantially all of the assets of the Company, a liquidation or dissolution of the Company, the failure of the common stock to be listed or quoted on any of The New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market, and certain other events as more fully described in the indenture relating to the 6.75% convertible notes, a holder thereof will have the option to require the Company to repurchase for cash all or any portion of such notes at a repurchase price equal to 100% of the principal amount of the notes being repurchased, plus accrued and unpaid interest (including additional interest, if any) to, but excluding, the repurchase date.

On or after June 15, 2013, in the event that the last reported price of the Company’s common stock exceeds the conversion price then in effect for 20 or more trading days during any 30 consecutive trading day period ending within five trading days prior to the date the Company receives a notice of conversion, the Company will, in addition to delivering shares upon conversion of the 6.75% convertible notes (and cash in lieu of fractional shares), make a “make-whole premium” payment in cash, shares of Company common stock or a combination thereof, subject to certain limitations, at the option of the Company, equal to the sum of the remaining scheduled payments of interest that would have been made on the 6.75% convertible notes to be converted had such notes remained outstanding through the earlier of the date that is three years after the date the Company receives the notice of conversion and June 15, 2017. If the Company elects to pay some or all of the “make-whole premium” in shares of the Company’s common stock, then the number of shares of common stock a holder will receive will be that number of shares that have a value equal to the amount of the “make-whole premium” payment to be paid to such holder in shares, divided by the product of 0.97 and the average of the last reported sale prices of the common stock for the five trading days immediately preceding, and including, the third trading day immediately prior to the conversion date; provided that in no event will such price be less than $3.00.

The Company can redeem all or any part of the 6.75% convertible notes for cash on or after June 15, 2015 if the last reported sale price of its common stock exceeds 150% of the conversion price then in effect for at least 20 trading days during any 30 consecutive trading day period ending within five trading days prior to the notice of redemption and certain other conditions are met (referred to as the provisional redemption). The redemption price will equal the principal amount of the convertible notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date, plus a “make-whole premium” payment in cash, shares of the Company’s common stock or a combination thereof, subject to certain limitations, at the option of the Company, equal to the sum of the remaining scheduled payments of interest that would have been made on the 6.75% convertible notes to be redeemed had such notes remained outstanding from the redemption date to June 15, 2017. If the Company elects to pay some or all of the “make-whole premium” in shares of the Company’s common stock, then the number of shares of common stock a holder will receive will be that number of shares that have a value equal to the amount of the “make-whole premium” payment to be paid to such holder in shares, divided by the product of 0.97 and the average of the last reported sale prices of the Company’s common stock for the five trading days immediately preceding, and including, the third trading day immediately prior to the redemption date; provided that in no event will such price be less than $3.00.

If there is an event of default under the notes, the principal of and premium, if any, on all the notes and the interest accrued thereon may be declared immediately due and payable, subject to certain conditions set forth in the indenture.

21

Events of default under the indenture include, but are not limited to, the Company: (i) becoming delinquent in making certain payments due under the notes; (ii) failing to deliver shares of common stock or cash upon conversion of the notes; (iii) failing to deliver certain required notices under the notes; (iv) incurring certain events of default with respect to other indebtedness or obligations; (v) becoming subject to certain bankruptcy proceedings or orders; or (vi) failing to pay or the acceleration of other indebtedness. If the Company fails to file certain periodic reports with the SEC, it will be required to make additional interest payments. As of March 29, 2013, no events of default have occurred.

The indenture relating to the 6.75% convertible notes contains a covenant that limits the Company’s ability to incur Indebtedness, as that term is defined in the indenture, secured by a lien on the Company’s assets or any Indebtedness that is senior to, or equal to, the 6.75% convertible notes, or permit any subsidiary to do so, other than a senior secured credit facility financing in an aggregate principal amount not to exceed $35.0 million, and any subsidiary guarantees required thereunder, or any other Indebtedness outstanding as of the date of the indenture.

For financial accounting purposes, the requirements for the Company to make additional interest payments in the event of early redemption by the Company and to make additional interest payments in the event that the Company does not timely file certain periodic reports with the SEC are embedded derivatives. As of March 29, 2013, the fair value of these embedded derivatives has been estimated and is not significant. The Company’s contingent obligation to make an interest make-whole premium payment in the event of an early conversion by the holders of the notes is also an embedded derivative. As of March 29, 2013, the fair value of this contingent obligation has been estimated at $174,000 and is recorded in other liabilities.

The estimated fair value of these notes as of March 29, 2013 was approximately $40.9 million and was calculated using an option pricing model with Level 3 inputs. Key assumptions used in the calculation of this fair value include a volatility of 70.4%, based on the implied volatility of a Mindspeed publicly traded call option, a debt discount rate of 9.0% and discount for lack of marketability of 10.0%.

The Company incurred $492,000 of debt issuance costs, which is being amortized to interest expense over the term of the convertible notes through June 15, 2017 using the effective interest method. At March 29, 2013, debt issuance costs of $414,000, net of accumulated amortization, were included in other assets.

The Company is eligible to borrow amounts against the revolving credit facility up to the amount allowable by the borrowing base. The borrowing base is calculated on a monthly basis and is based on the amount of the Company’s eligible accounts receivable. At March 29, 2013, the Company had an outstanding revolving credit facility balance of $13.5 million and the amount of the eligible borrowing base was $15.9 million. To the extent that the eligible borrowing base is reduced, the Company is required to pay down the outstanding revolving credit facility balance to the amount of the eligible borrowing base. During the next 12 months, the Company expects the borrowing base will be sufficient to maintain borrowings on the revolving credit facility at a minimum of $8.0 million. Consequently, it has classified $8.0 million of the revolving credit facility as a long-term liability.

The Company has the option to choose, with a few exceptions, whether the term loan facility and the revolving credit facility bear interest based on a base rate, which is the prime rate published in The Wall Street Journal, or a LIBOR rate, which has a floor of 0.75%. A base rate facility will bear interest ranging from the base rate plus 1.25% to base rate plus 1.75%. A LIBOR rate facility will bear interest ranging from LIBOR rate plus 3.25% to LIBOR rate plus 3.75%. Both the base rate margin and LIBOR margin vary based upon the Company’s liquidity ratio. As of March 29, 2013, the interest rate on both the term loan facility and the revolving credit facility was 4.00%. Total interest expense incurred on the term loan facility and revolving credit facility was $225,000 and $531,000 for the three and six months ended March 29, 2013, respectively.

The revolving credit facility is subject to an unused line of credit fee. This fee is payable quarterly in an amount equal to 0.25% - 0.50% of the average daily unused portion of the credit facility. The unused line fee will vary based upon the Company’s liquidity ratio.

The loan and security agreement, as amended, requires the Company to meet certain financial covenants. Beginning in the third quarter of fiscal 2013, the Company must maintain a minimum cash and cash equivalents balance of $35.0 million with Silicon Valley Bank and a minimum liquidity ratio of 1.40. For each subsequent fiscal quarter, the minimum cash and cash equivalents balance is reduced to $20.0 million. If the Company fails to maintain the minimum cash and cash equivalents level and liquidity ratio during the third quarter of fiscal 2013, it will be required to maintain a minimum cash and cash equivalents balance of $30.0 million, a minimum liquidity ratio of 1.25 and a minimum adjusted EBITDA of $1.5 million. For each fiscal quarter subsequent to the third quarter of fiscal 2013, if the Company fails to maintain the minimum $20.0 million cash and cash equivalents balance and the minimum 1.40 liquidity ratio, it will be required to maintain a minimum cash and cash equivalents balance of $15.0 million, a minimum liquidity ratio of 1.25 and a minimum fixed charge coverage ratio of 1.10.

The Company incurred approximately $537,000 of debt issuance costs related to the loan and security agreement, which are being amortized to interest expense over the term of the facility through February 6, 2017 using the effective interest method. At March 29, 2012, debt issuance costs of $301,000, net of accumulated amortization, were included in other assets.

6.50% Convertible Senior Notes

On July 30, 2008, the Company entered into separate exchange agreements with certain holders of its previously outstanding 3.75% convertible senior notes, pursuant to which holders of an aggregate of $15.0 million of the notes agreed to exchange their notes for $15.0 million in aggregate principal amount of a new series of 6.50% convertible senior notes due in August 2013 (the Exchange Offer). The Exchange Offer closed on August 1, 2008. The Company paid at the closing an aggregate of approximately $100,000 in accrued and unpaid interest on the 3.75% convertible senior notes that were exchanged for the 6.50% convertible senior notes, as well as approximately $900,000 in transaction fees.

The 6.50% convertible senior notes are convertible at the option of the holders, at any time on or prior to maturity, into shares of the Company’s common stock at a conversion rate initially equal to approximately $4.74 per share of common stock, which is subject to adjustment in certain circumstances. Upon conversion of the notes, the Company generally has the right to deliver to the holders thereof, at the Company’s option: (i) cash; (ii) shares of the Company’s common stock; or (iii) a combination thereof. The initial conversion price of the 6.50% convertible senior notes will be adjusted to reflect stock dividends, stock splits, issuances of rights to purchase shares of the Company’s common stock, and upon other events. If the Company undergoes certain fundamental changes prior to maturity of the notes, the holders thereof will have the right, at their option, to require it to repurchase for cash some or all of their 6.50% convertible senior notes at a repurchase price equal to 100% of the principal amount of the notes being repurchased, plus accrued and unpaid interest (including additional interest, if any) to, but not including, the repurchase date, or convert the notes into shares of its common stock and, under certain circumstances, receive additional shares of its common stock in the amount provided in the indenture.

The estimated fair value of these notes as of March 29, 2013 was approximately $13.4 million and was calculated using an option pricing model with Level 3 inputs. Key assumptions used in the calculation of this fair value include a volatility of 50.5%, based on the implied volatility of a Mindspeed publicly traded call option, a debt discount rate of 9.0% and discount for lack of marketability of 10.0%.

The Company’s contingent obligation to issue additional shares or make additional cash payment upon conversion following a fundamental change is considered an embedded derivative. As of March 29, 2013, the liability under the fundamental change adjustment has been recorded at its estimated fair value and is not significant.

8. Commitments and Contingencies

In January 2013, Clark Leips, a purported shareholder of the Company, filed a lawsuit against the Company and its board of directors in the United States District Court for the District of Delaware alleging, among other things, that the compensation and management development committee of the board of directors breached its fiduciary duties in each of calendar years 2009, 2010, 2011 and 2012 by approving equity incentive grants for the Company’s chief executive officer that exceeded the respective sub-limitations under Section 5 of the Company’s 2003 long-term incentives plan for grants to a single participant in any calendar year. Plaintiff also alleged that the disclosures in the proxy statement for the Company’s 2013 annual meeting of stockholders are inadequate. The plaintiff seeks, among other things, damages, rescission of the excess grants, disgorgement and attorney’s fees. Plaintiff filed a motion to enjoin the Company’s 2013 annual meeting of stockholders until the Company issued additional disclosures to supplement the proxy statement. On January 22, 2013, the Company filed a supplement to the proxy statement. The motion for an injunction was then withdrawn by the plaintiff. The Company and its board of directors have moved to dismiss the complaint. Management does not believe the resolution of this matter will result in a material adverse impact on the Company’s financial position, results of operations or cash flows.

In addition, various lawsuits, claims and proceedings have been or may be instituted or asserted against the Company, including those pertaining to product liability, intellectual property, environmental, safety and health and employment matters. As is common in the industry, the Company currently has in effect a number of agreements in which it has agreed to defend, indemnify and hold harmless certain of its suppliers and customers from damages and costs which may arise from the infringement by the Company’s products of third-party patents, trademarks or other proprietary rights. The Company has not incurred significant costs to defend lawsuits or settle claims related to these indemnification agreements.

The outcome of litigation cannot be predicted with certainty and some lawsuits, claims or proceedings may be determined unfavorably against the Company. Based on its evaluation of matters which are pending or asserted, while there can be no assurance, management of the Company believes the disposition of such matters will not have a material adverse effect on the financial condition or results of operations of the Company.

9. Restructuring Charges

The Company has, and may in the future, commit to restructuring plans to help manage the costs of the Company or to help implement strategic initiatives, among other reasons.

Fourth Quarter of Fiscal 2012 Restructuring Plan –In the fourth quarter of fiscal 2012, the Company committed to the implementation of a restructuring plan, which consisted primarily of a headcount reduction in the Company’s research and development functions and selling, general and administrative functions. The restructuring plan is expected to be substantially completed during the fourth quarter of fiscal 2013. The Company made the decision to implement the restructuring in furtherance of its efforts to reduce operating expenses and cash consumption. Approximately $3.0 million in charges related to this plan were incurred since the plan’s inception through the second quarter of fiscal 2013. Of the charges incurred, $2.8 million related to severance costs for affected employees and approximately $206,000 related to contractual obligations on vacated office space. The Company expects to incur additional charges of $1.0 million to $2.0 million for a total plan charge of approximately $4.0 million to $5.0 million. The total cash expenditure for this plan is expected to be $3.5 million to $4.5 million. The remaining plan charges and cash expenditures will relate primarily to severance costs for affected employees.

25

Activity and liability balances related to the Company’s fourth quarter of fiscal 2012 restructuring plan from September 28, 2012 through March 29, 2013 were as follows:

	Workforce Reductions			Facilities and Other			Total
	(in thousands)
Restructuring balance, September 28, 2012	$	382		$	—		$	382
Charges to costs and expenses		1,362			210			1,572
Cash payments		(993	)		—			(993	)
Non-cash adjustments		(97	)		(4	)		(101	)
Restructuring balance, December 28, 2012	$	654		$	206		$	860
Charges to costs and expenses		676			—			676
Cash payments		(792	)		(22	)		(814	)
Non-cash adjustments		92			—			92
Restructuring balance, March 29, 2013	$	630		$	184		$	814

The remaining accrued restructuring balance principally represents employee severance costs and contractual obligations on vacated office space. The Company expects to pay these remaining employee severance obligations through the fourth quarter of fiscal 2013 and the remaining contractual obligations on vacated office space through the second quarter of fiscal 2015, the end of the related lease term.

Fourth Quarter of Fiscal 2011 Restructuring Plan –In the fourth quarter of fiscal 2011, the Company implemented a restructuring plan, which consisted primarily of a targeted headcount reduction in the selling, general and administrative functions and WAN product line, which is now part of the communications processors product line. The Company incurred $1.2 million of charges related to severance costs for the affected employees. The restructuring plan was substantially completed during the fourth quarter of fiscal 2011.

Activity and liability balances related to the Company’s fourth quarter of fiscal 2011 restructuring plan from September 28, 2012 through March 29, 2013 were as follows:

	Workforce Reductions
	(in thousands)
Restructuring balance, September 28, 2012	$	45
Cash payments		(13	)
Restructuring balance, December 28, 2012 and March 29, 2013	$	32

The remaining accrued restructuring balance principally represents employee severance costs. The Company expects to pay these remaining obligations through the third quarter of fiscal 2013.

10. Income Taxes

The Company utilizes the liability method of accounting for income taxes. The federal statutory rate was 34% for all periods. The difference between the Company’s effective tax rate and the federal statutory rate for fiscal 2012 is primarily due to the full valuation allowance offsetting any current period benefit from operating losses and the effect of foreign earnings taxed at rates differing from the federal statutory rate. The difference between the Company’s effective tax rate and the federal statutory rate for fiscal 2013 is primarily due to a goodwill impairment charge, changes in the Company’s valuation allowance offsetting current period benefit from operating losses and the effect of foreign earnings taxed at rates differing from the federal statutory rate.

26

11. Related Party Transactions

In June 2011, the Company entered into an agreement to license certain intellectual property from a related party. The licensor is a related party because one of the Company’s directors also serves as a director of the licensor and one of the Company’s members of management serves on the licensor’s technical advisory board. Pursuant to terms of the license agreement, the Company will pay an aggregate of $6.3 million upon the completion of certain milestones, including the delivery of licensed intellectual property. In addition, the Company is obligated to pay royalties not to exceed an additional $2.2 million for products sold that include the licensed intellectual property. As of March 29, 2013, the Company has paid $5.4 million in related license fees and has recorded the payments in intangible assets, net, on its consolidated condensed balance sheet.

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

This information should be read in conjunction with our unaudited consolidated condensed financial statements and the notes thereto included in this Quarterly Report on Form 10-Q and our audited consolidated financial statements and notes thereto and Management’s Discussion and Analysis of Financial Condition and Results of Operations contained in our Annual Report on Form 10-K for our fiscal year ended September 28, 2012.

Overview

Mindspeed Technologies, Inc. designs, develops and sells semiconductor solutions for communications applications in wireline and wireless network infrastructure equipment, which includes broadband access networks (fixed and mobile), enterprise and metropolitan and wide area networks (WAN) (fixed and mobile). In previous fiscal years, we had organized our solutions for these interrelated and rapidly converging networks into three product lines: communications convergence processing, high-performance analog and WAN communications. As previously reported, communications convergence processing included small cell wireless equipment. Beginning in fiscal 2013, to better align with our investment focus and provide greater transparency into the execution of our growth business, we started reporting small cell wireless infrastructure revenues as a standalone category. We also combined the communications convergence processing, excluding small cell wireless infrastructure revenues, and WAN businesses into communications processors. High-performance analog remained unchanged. Therefore, our three product lines are wireless infrastructure, communications processors and high-performance analog. Our wireless infrastructure products include ultra-low-power, multi-core digital signal processor (DSP) system-on-chip (SoC) products for the mobile (3G/4G) carrier infrastructure, including residential and enterprise platforms. Our communications processors products include ultra-low-power, multi-core digital signal processor (DSP) system-on-chip (SoC) products for the fixed and mobile carrier infrastructure platforms and WAN communication products that help optimize today’s circuit-switched networks that furnish much of the Internet’s underlying long-distance infrastructure. Our high-performance analog products include high-density crosspoint switches, optical drivers, equalization and signal-conditioning solutions that solve difficult switching, timing and synchronization challenges in next-generation optical networking, enterprise storage and broadcast video transmission applications.

Our products are sold to original equipment manufacturers (OEMs) for use in a variety of network infrastructure equipment, including:

• Wireless Infrastructure – 3G/4G long-term evolution (LTE) wireless small cell base stations in the carrier infrastructure, including residential and enterprise;

• Communications Processors – triple-play access gateways for Voice-over-Internet Protocol (VoIP) and data processing platforms; broadband customer premises equipment (CPE) gateways and other equipment that carriers use to deliver voice, data and video services to residential subscribers; Internet Protocol (IP) private branch exchange (PBX) equipment and security appliances used in the enterprise and circuit-switched networking equipment that implements asynchronous transfer mode (ATM) and T1/E1 and T3/E3 communications protocols; and

• High-Performance Analog – next-generation fiber access network equipment (including passive optical networking, or PON, systems); switching and signal conditioning products supporting fiber-to-the-premise, optical transport networks (OTN), storage and server systems and broadcast video, inclusive of routers and other systems that are driving the migration to 3G high-definition (HD) transmission.

Our customers include Alcatel-Lucent SA, Cisco Systems, Inc., Huawei Technologies Co. Ltd., Hitachi Ltd., LM Ericsson Telephone Company, Mitsubishi Electric Corporation, Nokia Siemens Networks and Zhongxing Telecom Equipment Corp., among others.

Trends and Factors Affecting Our Business

Our products are components of network infrastructure equipment. As a result, we rely on network infrastructure OEMs to select our products from among alternative offerings to be designed into their equipment. These “design wins”

28

are an integral part of the long sales cycle for our products. Our customers may need six months or longer to test and evaluate our products and an additional six months or more to begin volume production of equipment that incorporates our products. We believe our close relationships with leading network infrastructure OEMs facilitate early adoption of our products during development of their products, enhance our ability to obtain design wins and encourage adoption of our technology by the industry. We believe our diverse portfolio of semiconductor solutions has us well positioned to capitalize on some of the most significant trends in telecommunications spending, including: next generation network convergence; VoIP/fiber access deployment in developing and developed markets; 3G/4G wireless infrastructure build-out; the adoption of higher speed interconnectivity solutions; and the migration of broadcast video to HD. Based on a recent review of target markets addressed by our wireless infrastructure reporting unit, we believe that the pace and timing of deployments within that market will be pushed out beyond our previously forecasted plans. As a result of these changes in our assessment of the reporting unit’s near-term prospects, we recognized related goodwill and asset impairment charges totaling $33.4 million in the second quarter of fiscal 2013.

We market and sell our semiconductor products directly to network infrastructure OEMs. We also sell our products indirectly through electronic component distributors and third-party electronic manufacturing service providers, who manufacture products incorporating our semiconductor networking solutions for OEMs. Sales to distributors accounted for approximately 70% of our net revenue in our second fiscal quarter and 66% of our net revenue for the first six months of fiscal 2013. We generated approximately 81% of our net revenue in our fiscal second quarter and 77% of our net revenue for the first six months of fiscal 2013 from outside of the Americas. We believe a portion of the products we sell to OEMs and third-party manufacturing service providers in the Asia-Pacific region is ultimately shipped to end markets in the Americas and Europe. We generated approximately 33% of our net revenue in our second fiscal quarter and 31% of our net revenue for the first six months of fiscal 2013 from customers in China.

We have significant research, development, engineering and product design capabilities. Our success depends to a substantial degree upon our ability to develop and introduce in a timely fashion new products and enhancements to our existing products that meet changing customer requirements and emerging industry standards. We have made, and plan to make, substantial investments in research and development and to participate in the formulation of industry standards. We spent approximately $16.1 million in our second fiscal quarter and approximately $31.7 million in the first six months of fiscal 2013 on research and development. We seek to maximize our return on our research and development spending by focusing our research and development investment in what we believe are key growth markets, including wireless infrastructure solutions for small cell base station processing, communications processors for high-bandwidth multiservice access applications, and high-performance analog applications such as optical networking and broadcast-video transmission. We have completed a series of cost reduction actions, which have improved our operating cost structure, and we will continue to perform additional actions, when necessary.

We are dependent upon third parties for the development, manufacturing, assembly and testing of our products. Our ability to bring new products to market, to fulfill orders and to achieve long-term revenue growth is dependent upon our ability to obtain sufficient external manufacturing capacity, including wafer fabrication capacity. Periods of upturn in the semiconductor industry may be characterized by rapid increases in demand and a shortage of capacity for wafer fabrication and assembly and test services. In such periods, we may experience longer lead times or indeterminate delivery schedules, which may adversely affect our ability to fulfill orders for our products. During periods of capacity shortages for manufacturing, assembly and testing services, our primary foundries and other suppliers may devote their limited capacity to fulfill the requirements of their other customers that are larger than we are, or who have superior contractual rights to enforce manufacture of their products, including to the exclusion of producing our products. The foundries and other suppliers on whom we rely may experience financial difficulties or suffer disruptions in their operations due to causes beyond our control, including deteriorations in general economic conditions, labor strikes, work stoppages, electrical power outages, fire, earthquake, flooding or other natural disasters. We may also incur increased manufacturing costs, including costs of finding acceptable alternative foundries or assembly and test service providers. In order to achieve sustained profitability and positive cash flows from operations, we may need to further reduce operating expenses and/or increase our revenue.

Our ability to achieve revenue growth will depend on increased demand for network infrastructure equipment that incorporates our products, which in turn depends primarily on the level of capital spending by communications service providers, the level of which may decrease due to general economic conditions and uncertainty, over which we have no control. We believe the market for network infrastructure equipment in general, and for communications semiconductors in particular, offers attractive long-term growth prospects due to increasing demand for network capacity, the continued upgrading and expansion of existing networks and the build-out of telecommunication networks in developing countries. However, the semiconductor industry is highly cyclical and is characterized by constant and rapid technological change,

29

rapid product obsolescence and price erosion, evolving technical standards, short product life cycles and wide fluctuations in product supply and demand. In addition, there has been an increasing trend toward industry consolidation, particularly among major network equipment and telecommunications companies. Consolidation in the industry has generally led to pricing pressure and loss of market share. These factors have caused substantial fluctuations in our revenue and our results of operations in the past, and we may experience cyclical fluctuations in our business in the future.

On April 30, 2013, we issued a press release announcing that we have engaged Morgan Stanley & Co. LLC to assist us in evaluating various strategic alternatives available to our company. The strategic review will require the expenditure of significant time and resources by our company and management team. The strategic review could also distract our executives, employees, and board of directors from other matters relating to the operation of our businesses and affect our ability to attract and retain new executives or key employees. In addition, our announcement of the strategic review may have created and may continue to create uncertainty among current and potential partners, suppliers and customers. In particular, these partners, suppliers and customers could question our commitment to continuing particular product lines or markets or operating as an independent business. As a result of these factors, the announcement could potentially undermine our business and have a material adverse effect on our results of operations or financial condition. In addition, the announcement and subsequent developments could cause increased volatility in our stock price.

Critical Accounting Policies and Estimates

The accounting policies that have the greatest impact on our financial condition and results of operations and that require the most judgment are those relating to inventories, stock-based compensation, revenue recognition, deferred income taxes and uncertain tax positions, business combinations, goodwill and other long-lived assets, and impairment of goodwill and other long-lived assets. These policies are described in further detail in our Annual Report on Form 10-K for the fiscal year ended September 28, 2012. There have been no significant changes in our critical accounting policies and estimates during the first six months ending March 29, 2013 as compared to what was previously disclosed in our Annual Report on Form 10-K for the fiscal year ended September 28, 2012.

Recent Accounting Pronouncements

In February 2013, the FASB issued accounting guidance which requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component and to present significant amounts reclassified out of accumulated other comprehensive income by respective line items of net income if the amount reclassified is required to be reclassified to net income in its entirety. For amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional details about those amounts. The provisions of this guidance will be effective for us in our first quarter of fiscal 2014 and should be applied prospectively. We do not expect the adoption of this guidance to have a material impact on our consolidated condensed financial statements.

In October 2012, the FASB issued accounting guidance covering a wide range of topics in the Accounting Standards Codification. These amendments include technical corrections and improvements to the Accounting Standards Codification and conforming amendments related to fair value measurements. The amendments in this update were effective for fiscal periods beginning after December 15, 2012. The adoption of this guidance did not have a material impact on our consolidated condensed financial statements.

Net revenue	$	35,385		100	%	$	35,359		100	%	$	26			0.1	%

Net revenue from wireless infrastructure products increased in the second quarter of fiscal 2013 when compared to the second quarter of fiscal 2012 due to increased shipments of our SoC products for small cell base stations, including products shipped to the 4G/LTE market. Net revenue from our communications processors products were approximately flat in the second quarter of fiscal 2013 when compared to the second quarter of fiscal 2012, despite an increase in Ethernet products for wide area networks.

The following table summarizes fiscal year-to-date net revenue by our product lines:

Net revenue	$	79,779		100	%	$	69,291		100	%	$	10,488			15.1	%

Net revenue from high-performance analog products increased in the first six months of fiscal 2013 when compared to the first six months of fiscal 2012 due to increased demand for crosspoint switches and optical physical media devices. Net revenue from wireless infrastructure products also increased in the first six months of fiscal 2013 when compared to the first six months of fiscal 2012 due to increased shipments of our SoC products for small cell base stations, as well as increased sales of 3G/HSPA products driven by the acquisition of picoChip in February of 2012. These increases were partially offset by a decrease in sales in communications processors products. Net revenue from our communications processors products decreased in the first six months of fiscal 2013 when compared to the first six months of fiscal 2012, despite the increase in demand for Ethernet products for wide area networks. The decline is due to a slowdown in the infrastructure voice market, as well as a decrease in shipments of CPE products, which are used in broadband CPE gateways and other equipment that service providers are deploying in order to deliver voice, data and video services to residential subscribers.

In the second quarter of fiscal 2013, we did not sell any intellectual property compared to $501,000 sold in the second quarter of fiscal 2012. We sold $6.0 million in intellectual property during the first six months of fiscal 2013 compared to $591,000 in intellectual property sales in the first six months of fiscal 2012. We have developed and maintain a broad intellectual property portfolio, and we may periodically enter into strategic arrangements to leverage our portfolio by licensing or selling our intellectual property.

The demand environment in the markets in which we participate is dynamic and certain customers increase or accelerate product orders to earn financial incentives near quarter end, while other customers request product shipments in the quarter that exceed our available supply. The net impact of these activities was a decrease to net revenue of $59,000 for the second quarter of fiscal 2013 and the six months ended March 29, 2013 and an increase to net revenue of $579,000 for the second quarter of fiscal 2012 and the six months ended March 30, 2012.

Impairment of Long-Lived Assets

During the second quarter of fiscal 2013, in conjunction with the evaluation of goodwill and indefinite-lived intangibles, as discussed below, we believed there were impairment triggering events and circumstances which warranted an evaluation of certain definite-lived intangible assets. These circumstances included lower revenue when compared with projected results, which led to weaker performance than we expected for the second quarter of fiscal 2013. Specifically, the carrying amounts of certain intellectual property licenses and photomasks within our wireless infrastructure reporting unit were determined not to be recoverable and to exceed their fair value. Accordingly, we impaired the entire carrying value of these intellectual property licenses and photomasks and recorded an impairment charge of $2.0 million on intellectual property licenses and $439,000 on photomasks in cost of goods sold on our unaudited consolidated condensed statements of operations. We reviewed our other long-lived assets within our wireless infrastructure reporting unit and did not identify any other impairment.

Gross Margin

Gross margin represents net revenue less cost of goods sold. As a fabless semiconductor company, we use third parties, including Taiwan Semiconductor Manufacturing Co., Ltd. (TSMC), Amkor Technology, Inc., Unisem, Inc. and Advanced Semiconductor Engineering, Inc. (ASE), for wafer fabrication and assembly and test services. Cost of goods sold primarily consisted of: purchased finished wafers; assembly and test services; royalty and other intellectual property costs; labor and overhead costs associated with product procurement; asset impairments; amortization of the cost of mask sets purchased; and sustaining engineering expenses pertaining to products sold.

	(in thousands, except percentages)
Gross margin	$	18,770		53	%	$	20,520		58	%	$	(1,750	)		-8.5	%

The decrease in our gross margin as a percent of net revenue for the second quarter of fiscal 2013 compared to the second quarter of fiscal 2012 was driven primarily by $2.4 million of asset impairments recorded in cost of goods sold, which related to the impairment of intellectual property licenses and photomasks during the second quarter of fiscal 2013, as described above. The decrease in gross margin was also due to a decrease in intellectual property revenue, which had little associated cost and the amortization of acquired intangible assets related to the picoChip acquisition. These decreases were partially offset by an increase in our gross margin due to a change in product mix, including a larger amount of revenue from our WAN products for the second quarter of fiscal 2013 compared to the second quarter of fiscal 2012.

Gross margin	$	48,070		60	%	$	40,233		58	%	$	7,837		19.5	%

Gross margin increased for the first six months of fiscal 2013 compared to the first six months of fiscal 2012 due to a $5.9 million increase in intellectual property revenue. The increase in our gross margin as a percent of net revenue for the first six months of fiscal 2013 compared to the first six months of fiscal 2012 was driven primarily by a change in product mix, as described above, as well as an increase in intellectual property revenue, which had no associated cost. These increases in gross margin as a percent of net revenue were partially offset by the amortization of acquired intangible assets related to the picoChip acquisition and $2.4 million of asset impairments recorded in cost of goods sold, which related to the impairment of intellectual property licenses and photomasks during the second quarter of fiscal 2013, as described above.

Research and Development

Research and development (R&D) expenses consisted primarily of: direct personnel costs, including stock-based compensation; photomasks; electronic design automation tools; and pre-production evaluation and test costs.

The following table presents details of fiscal quarter R&D expenses:

	Three Months Ended
	March 29, 2013			% of Net Revenue			March 30, 2012		% of Net Revenue			Change

Research and development	$	16,106			46	%	$	17,740		50	%	$	(1,634	)		-9.2	%

R&D expenses decreased by approximately $1.6 million for the second quarter of fiscal 2013 compared to the second quarter of fiscal 2012 due primarily to design and development cost reductions as part of the restructuring plan we undertook in fiscal 2012 and a decrease in other R&D expense primarily due to $237,000 of certain non-recurring engineering reimbursements during fiscal 2013from our customers related to the development of certain products or product features. Personnel-related costs also decreased for the second quarter of fiscal 2013 compared to the second quarter of fiscal 2012. This decrease was primarily due to the restructuring activities that began in late fiscal 2012.

The following table presents details of fiscal year-to-date R&D expenses:

Research and development	$	31,703		40	%	$	32,748		47	%	$	(1,045	)		-3.2	%

R&D expenses decreased by approximately $1.0 million for the first six months of fiscal 2013 compared to the first six months of fiscal 2012 due to design and development cost reductions as part of the restructuring plan we undertook in fiscal 2012. Other R&D expense decreased primarily due to $489,000 of certain non-recurring engineering reimbursements during fiscal 2013from our customers related to the development of certain products or product features. These decreases were partially offset due to increased facilities and depreciation expense related to the additional facilities and property, plant and equipment obtained through the acquisition of picoChip.

Selling, General and Administrative

Our selling, general and administrative (SG&A) expenses include personnel costs, independent sales representative commissions and product marketing, applications engineering and other marketing costs. Our SG&A expenses also include costs of corporate functions, including accounting, finance, legal, human resources, information systems and communications.

SG&A expenses decreased for the second quarter of fiscal 2013 compared to the second quarter of fiscal 2012 primarily due to decreased personnel-related costs associated with the restructuring plan announced in fiscal 2012. Other SG&A expenses decreased due primarily to a decrease of $1.3 million in picoChip integration costs incurred in the second quarter of fiscal 2013 compared to the second quarter of fiscal 2012. These decreases were partially offset by an increase in professional fees and outside services.

The following table presents details of fiscal year-to-date SG&A expenses:

Selling, general and administrative	$	19,781		25	%	$	22,410		32	%	$	(2,629	)		-11.7	%

SG&A expenses decreased for the first six months of fiscal 2013 compared to the first six months of fiscal 2012 primarily due to decreased personnel-related costs associated with the restructuring plan announced in fiscal 2012. Other SG&A expenses decreased due primarily to a decrease of $1.5 million in picoChip integration costs incurred in the second quarter of fiscal 2013 compared to the second quarter of fiscal 2012. These decreases were partially offset by an increase in professional fees and outside services.

Impairment of Goodwill and Indefinite-Lived Intangibles

During the second quarter of fiscal 2013, we performed an interim evaluation of goodwill, definite-lived intangibles and indefinite-lived intangibles for our wireless infrastructure reporting unit as we believed there were impairment triggering circumstances which warranted an evaluation. These circumstances consisted of actual and projected decreases in net revenue due to slower than expected deployments of 3G small cell base stations, as compared to prior projections at the time of our acquisition of picoChip.

Prior to performing step one of the goodwill impairment test, we determined the carrying amount of the in-process research and development (IPR&D) within our wireless infrastructure reporting unit exceeded its fair value. The fair value was determined using the multiple period excess earnings method. See Note 3 to our consolidated condensed financial statements for a description of the significant unobservable inputs used. As a result, we recorded a $500,000 impairment charge on our IPR&D as of March 29, 2013.

34

Given the triggering circumstances, we performed step one of the impairment test for goodwill and determined that the fair value of the wireless infrastructure reporting unit, which was based on a combination of the income approach and market approach, was lower than the carrying value. Under the income approach, the fair value of the reporting unit was calculated based on the present value of estimated future net cash flows. Cash flows beyond the discrete forecast were estimated using a terminal value calculation, which incorporated historical and forecasted financial trends for the wireless infrastructure reporting unit and considered perpetual earnings growth rates for publicly traded peer companies. Future cash flows were discounted to present value by incorporating appropriate present value techniques. Under the market approach, fair value was estimated based on market multiples of revenue and earnings or similar measures for comparable companies, when available.

Specifically, the income approach valuation included the following assumptions:

	March 29, 2013
Discount rate		21.0	%
Perpetual growth rate		4.0	%
Tax rate		29.3	%
Risk free rate		2.7	%
Peer company beta		1.32
Country risk adjustment for foreign operations		0.7	%

The failure of step one of the goodwill impairment test triggered a step two impairment analysis. The second step of the goodwill impairment test involved comparing the implied fair value of the reporting unit’s goodwill with the carrying value of that goodwill. The amount by which the carrying value of the goodwill exceeded its implied fair value was recognized as an impairment loss. As a result, we recorded a charge for the impairment of goodwill in the amount of $30.5 million during the second quarter of fiscal 2013 related to our wireless infrastructure reporting unit.

We will continue to evaluate our goodwill on an annual basis during our fourth fiscal quarter and whenever events or changes in such circumstances as significant adverse changes in business climate or operating results, changes in management strategy or further significant declines in the trading price of our common stock indicate that there may be a potential impairment.

Acquisition-Related Costs

Acquisition-related costs for the first three and six months ended March 29, 2013 and March 30, 2012 consisted primarily of professional fees incurred as a result of our acquisition of picoChip, which was completed in February 2012.

Restructuring Charges

We have, and may in the future, commit to restructuring plans to help manage our costs or to help implement strategic initiatives, among other reasons.

Fourth Quarter of Fiscal 2012 Restructuring Plan –In the fourth quarter of fiscal 2012, we committed to the implementation of a restructuring plan, which consisted primarily of a headcount reduction in our research and development functions and selling, general and administrative functions. The restructuring plan is expected to be substantially completed during the fourth quarter of fiscal 2013. We made the decision to implement the restructuring plan in furtherance of our efforts to reduce operating expenses and cash consumption. Approximately $3.0 million in charges related to this plan were incurred since the plan’s inception through the second quarter of fiscal 2013. Of the amounts incurred, $2.8 million related to severance costs for affected employees and approximately $206,000 related to contractual obligations on vacated office space. We expect to incur additional charges of $1.0 million to $2.0 million for a total plan charge of approximately $4.0 million to $5.0 million. The total cash expenditure for this plan is expected to be $3.5 million to $4.5 million. The remaining plan charge and cash expenditure will each relate primarily to severance costs for affected employees.

35

Activity and liability balances related to our fourth quarter of fiscal 2012 restructuring plan from September 28, 2012 through March 29, 2013 were as follows:

	Workforce Reductions			Facilities and Other			Total
	(in thousands)
Restructuring balance, September 28, 2012	$	382		$	—		$	382
Charges to costs and expenses		1,362			210			1,572
Cash payments		(993	)		—			(993	)
Non-cash adjustments		(97	)		(4	)		(101	)
Restructuring balance, December 28, 2012	$	654		$	206		$	860
Charges to costs and expenses		676			—			676
Cash payments		(792	)		(22	)		(814	)
Non-cash adjustments		92			—			92
Restructuring balance, March 29, 2013	$	630		$	184		$	814

The remaining accrued restructuring balance principally represents employee severance costs and contractual obligations on vacated office space. We expect to pay these remaining employee severance obligations through the fourth quarter of fiscal 2013 and the remaining contractual obligations on vacated office space through the second quarter of fiscal 2015, the end of the related lease term.

Fourth Quarter of Fiscal 2011 Restructuring Plan –In the fourth quarter of fiscal 2011, we implemented a restructuring plan, which consisted primarily of a targeted headcount reduction in the selling, general and administrative functions and (WAN) product line, which is now part of the communications processors product line. We incurred $1.1 million of charges related to severance costs for the affected employees during the fourth quarter of fiscal 2011. The restructuring plan was substantially completed during the fourth quarter of fiscal 2011. An additional $138,000 of charges was incurred related to severance costs for the affected employees during the third quarter of fiscal 2012.

Activity and liability balances related to our fourth quarter of fiscal 2011 restructuring plan from September 28, 2012 through March 29, 2013 were as follows:

	Workforce Reductions
	(in thousands)
Restructuring balance, September 28, 2012	$	45
Cash payments		(13	)
Restructuring balance, December 28, 2012 and March 29, 2013	$	32

The remaining accrued restructuring balance principally represents employee severance costs. We expect to pay these remaining obligations through the third quarter of fiscal 2013.

Interest expense	$	2,680		3	%	$	959		1	%	$	1,721		179.5	%

For the three and six months ended March 29, 2013, interest expense consisted of interest on our 6.75% convertible senior notes, our loan and security agreement and our 6.50% convertible senior notes. For the three and six months ended March 30, 2012, interest expense primarily consisted of interest on our 6.50% convertible senior notes.

Other Income, Net

Other income, net, principally consisted of the change in fair value of contingent consideration, income from reimbursable foreign R&D incentives, foreign exchange gains and losses and other non-operating gains and losses. The following table presents fiscal second quarter other income, net:

	Three Months Ended

											$		%
	(in thousands, except percentages)
Other Income, Net	$	730		2	%	$	309		1	%	$	421		136.2	%

The increase in other income, net, in the second quarter of fiscal 2013 compared to the second quarter of fiscal 2012 primarily reflected a $367,000 gain from the settlement of foreign currency transactions, a $134,000 increase in reimbursable foreign R&D credit and an $81,000 increase in the fair value of a contingent obligation on our 6.75% convertible senior notes. The increase was partially offset due to a decrease of $68,000 in net foreign exchange gains from the remeasurement of account balances not denominated in our functional currency.

The following table presents fiscal year-to-date other income, net:

	Six Months Ended
	March 29, 2013		% of Net Revenue			March 30, 2012		% of Net Revenue			Change
											$		%
	(in thousands, except percentages)
Other Income, Net	$	746		1	%	$	611		1	%	$	135		22.1	%

The increase in other income, net, in the first six months of fiscal 2013 compared to the first six months of fiscal 2012 reflected a $367,000 gain from the settlement of foreign currency transactions and a $136,000 increase in reimbursable foreign R&D credit. The increase was partially offset due to an increase of $301,000 in net foreign exchange losses from the remeasurement of account balances not denominated in our functional currency.

Income Taxes

Our provision for income taxes for the first three and six months of fiscal 2013 and 2012 principally consisted of income taxes incurred by our foreign subsidiaries. As a result of our history of operating losses and the uncertainty of future operating results, we determined that it is more likely than not that the U.S. federal and state income tax benefits (principally net operating losses we can carry forward to future years) will not be realized. Based on available objective

37

evidence, we believe it is more likely than not that our deferred tax assets will not be realized. Accordingly, we continue to provide a full valuation allowance against our U.S. federal and state net deferred tax assets at March 29, 2013. Should sufficient positive objectively verifiable evidence of the realization of our net deferred tax assets exist at a future date, we would reverse any remaining valuation allowance to the extent supported by estimates of future taxable income at that time.

Liquidity and Capital Resources

Our principal source of liquidity is our existing cash and cash equivalent balance.

In order to achieve profitability and positive cash flows from operations, we may need to further reduce operating expenses, reduce capital expenditures, increase our gross margin and/or increase revenue. We have recently completed a series of cost reduction actions, which have improved our operating expense structure, and we will continue to perform additional actions, if necessary. In addition, we may commit to additional restructurings to help implement strategic initiatives. These restructurings and other cost saving measures alone may not allow us to achieve profitability. Our ability to maintain, or increase, gross margin will depend on our ability to obtain product cost reductions and better terms with our suppliers. Our ability to maintain, or increase, current revenue levels to achieve and sustain profitability will depend on demand for network infrastructure equipment that incorporates our products, which in turn depends primarily on the level of capital spending by communications service providers and enterprises, the level of which may decrease due to general economic conditions, and uncertainty, over which we have no control. We may be unable to increase current revenue and gross margin levels or sustain past and future expense reductions in subsequent periods. We may not be able to achieve sustained profitability.

As of March 29, 2013, we were obligated to make a $1.9 million net earnout payment due to the achievement of a product development milestone, to the shareholders of picoChip. We were also obligated to make a payment of approximately $3.5 million to the picoChip escrow account related to a research and development tax credit. On April 26, 2013, we and the picoChip selling shareholders’ representative entered into a settlement agreement whereby the parties agreed to settle all outstanding obligations under the acquisition agreement, including escrow claims, earnout payments and the net asset adjustment on the purchase price paid by us in connection with the acquisition. In connection with the settlement, we were relieved of our $1.9 million net earnout payment obligation, $3.5 million of payables owed to the escrow account related to a refundable R&D tax credit and received $1.0 million net in cash. This settlement will result in the recording of other income of $6.4 million during the third quarter of fiscal 2013. This settlement agreement releases us, the selling shareholders and the selling shareholders’ representative from all contingent consideration, claims and potential claims between the parties and the escrow account has been terminated.

We believe that our existing cash balances, cash expected to be generated from operations and our revolving credit facility will be sufficient to fund our operations, anticipated capital expenditures, working capital and other financing requirements, including principal and interest payments on debt obligations, for at least the next 12 months. We have principal payments of $375,000 due each quarter during calendar 2013 on our term loan with Silicon Valley Bank and $15.0 million of principal payments due in August 2013 on our 6.50% convertible notes. We have no other principal payments on debt obligations for the next 12 fiscal months. We may acquire our debt securities through privately negotiated transactions, tender offers, exchange offers (for new debt or other securities), redemptions or otherwise, upon such terms and at such prices as we may determine appropriate. We will need to continue a focused program of capital expenditures to meet our research and development and corporate requirements. We may also consider acquisition opportunities to extend our technology portfolio and design expertise and to expand our product offerings. In order to fund capital expenditures, increase our working capital, re-pay debt or complete any acquisitions, we may seek to obtain additional debt or equity financing. We may also need to seek additional debt or equity financing if we experience downturns or cyclical fluctuations in our business that are more severe or longer than anticipated, or if we fail to achieve anticipated revenue and expense levels. However, we cannot assure you that such financing will be available to us on favorable terms, or at all, particularly in light of recent economic conditions in the capital markets.

Cash and cash equivalents	$	46,572	$	49,098	$	(2,526	)

Cash and cash equivalents decreased primarily as a result of cash used in our investing and financing activities. The decrease was partially offset by cash provided by operating activities.

The following table presents the major components of the consolidated statements of cash flows:

Operating activities generated cash for the first six months of fiscal 2013 due to cash provided by net non-cash operating adjustments, partially offset by changes in operating assets and liabilities. Significant non-cash adjustments included goodwill and asset impairments, stock-based compensation expense, restructuring charges, depreciation and amortization. Net income was also adjusted for a decrease in prepaid and other current assets due to the receipt of an international tax receivable. Cash outflows related to an increase in our accounts receivable balance due to the timing of sales and the timing of cash collections. Cash outflows also related to a decrease in accrued restructuring charges due to payments made mainly on the restructuring plan implemented in the fourth quarter of fiscal 2012 and a decrease in accrued expenses and other current liabilities due to interest payments and payments made on accrued vendor balances.

Operating activities used cash for the first six months of fiscal 2012 due to our net loss and net cash used in changes in operating assets and liabilities, partially offset by cash provided by net non-cash operating activities. Significant non-cash operating expenses included stock-based compensation expense and depreciation and amortization. The changes in operating assets and liabilities that had a significant impact on cash used in operating activities included an increase in accounts receivable due to the timing of sales and collections and a decrease in accrued compensation and benefits mainly due to the payment of bonuses under our fiscal 2011 cash bonus plan in the first quarter of fiscal 2012. These cash outflows were partially offset by an increase in accounts payable due to the timing of payments and a decrease in inventories due to our focused efforts in decreasing our inventory on hand and increasing our inventory turns.

39

Investing Activities

Investing activities used cash for the first six months of fiscal 2013 due to payments under license agreements of $2.7 million and the purchase of property, plant and equipment of $2.4 million.

Investing activities used cash for the first six months of fiscal 2012 due to payments under license agreements of $7.3 million, the purchase of property, plant and equipment of $2.3 million and the acquisition of picoChip of $20.1 million.

Financing Activities

Financing activities used cash for the first six months of fiscal 2013 due to $858,000 in payments made related to shares of our common stock withheld from, or delivered by, employees in order to satisfy applicable tax withholding obligations in connection with the vesting of restricted stock and $110,000 in payments made on capital lease obligations. This cash outflow was partially offset by $915,000 in proceeds from equity compensation programs.

Financing activities provided cash for the first six months of fiscal 2012 due to $28.5 million in borrowings under our line of credit and term loan and $1.4 million in proceeds from equity compensation programs. These cash inflows were partially offset by $575,000 in payments made related to shares of our common stock withheld from, or delivered by, employees in order to satisfy applicable tax withholding obligations in connection with the vesting of restricted stock and $281,000 in payments made on capital lease obligations.

Revolving Credit Facilities and Long-Term Debt

6.75% Convertible Senior Notes

On June 19, 2012, we sold $32.0 million in aggregate principal amount of our 6.75% convertible senior notes due 2017 for net proceeds of $30.6 million. Interest on the 6.75% convertible notes is payable semi-annually on June 15 and December 15 in arrears in cash at a rate of 6.75% per year on the principal amount, accruing from June 19, 2012. The 6.75% convertible notes will mature on June 15, 2017, unless earlier repurchased, redeemed or converted. The 6.75% convertible notes are fully and unconditionally guaranteed on a senior, unsecured basis by certain of our subsidiaries. The effective interest rate was 7.73% for the second quarter of fiscal 2013 and 7.78% for the first six months of fiscal 2013. The interest expense for the $32.0 million convertible debt for the second quarter of fiscal 2013 was $618,000 and $1.2 million for the first six months of fiscal 2013.

The 6.75% convertible notes are convertible at an initial conversion rate of 256.4103 shares of our common stock per $1,000 principal amount of 6.75% convertible notes, subject to adjustment in certain circumstances. This is equivalent to an initial conversion price of $3.90 per share of common stock. Holders may convert the 6.75% convertible notes at any time prior to the close of business on the second scheduled trading day immediately preceding June 15, 2017. If we undergo certain fundamental changes prior to maturity of the notes, including a change of control, sale of all or substantially all of our assets, our liquidation or dissolution, the failure of our common stock to be listed or quoted on any of The New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market, and certain other events as more fully described in the indenture relating to the 6.75% convertible notes, a holder thereof will have the option to require us to repurchase for cash all or any portion of such notes at a repurchase price equal to 100% of the principal amount of the notes being repurchased, plus accrued and unpaid interest (including additional interest, if any) to, but excluding, the repurchase date.

On or after June 15, 2013, in the event that the last reported price of our common stock exceeds the conversion price then in effect for 20 or more trading days during any 30 consecutive trading day period ending within five trading days prior to the date we receive a notice of conversion, we will, in addition to delivering shares upon conversion of the 6.75% convertible notes (and cash in lieu of fractional shares), make a “make-whole premium” payment in cash, shares of our common stock or a combination thereof, subject to certain limitations, at our option, equal to the sum of the remaining scheduled payments of interest that would have been made on the 6.75% convertible notes to be converted had such notes remained outstanding through the earlier of the date that is three years after the date we receive the notice of conversion and June 15, 2017. If we elect to pay some or all of the “make-whole premium” in shares of our common stock, then the number of shares of common stock a holder will receive will be that number of shares that have a value equal to the amount of the “make-whole premium” payment to be paid to such holder in shares, divided by the product of 0.97 and the average of the last reported sale prices of the common stock for the five trading days immediately preceding, and including, the third trading day immediately prior to the conversion date; provided that in no event will such price be less than $3.00.

40

We can redeem all or any part of the 6.75% convertible notes for cash on or after June 15, 2015 if the last reported sale price of our common stock exceeds 150% of the conversion price then in effect for at least 20 trading days during any 30 consecutive trading day period ending within five trading days prior to the notice of redemption and certain other conditions are met (referred to as the provisional redemption). The redemption price will equal the principal amount of the convertible notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date, plus a “make-whole premium” payment in cash, shares of our common stock or a combination thereof, subject to certain limitations, at our option, equal to the sum of the remaining scheduled payments of interest that would have been made on the 6.75% convertible notes to be redeemed had such notes remained outstanding from the redemption date to June 15, 2017. If we elect to pay some or all of the “make-whole premium” in shares of our common stock, then the number of shares of common stock a holder will receive will be that number of shares that have a value equal to the amount of the “make-whole premium” payment to be paid to such holder in shares, divided by the product of 0.97 and the average of the last reported sale prices of our common stock for the five trading days immediately preceding, and including, the third trading day immediately prior to the redemption date; provided that in no event will such price be less than $3.00.

If there is an event of default under the notes, the principal of and premium, if any, on all the notes and the interest accrued thereon may be declared immediately due and payable, subject to certain conditions set forth in the indenture. An event of default under the indenture will occur if we: (i) are delinquent in making certain payments due under the notes; (ii) fail to deliver shares of common stock or cash upon conversion of the notes; (iii) fail to deliver certain required notices under the notes; (iv) incur certain events of default with respect to other indebtedness or obligations; (v) are subject to certain bankruptcy proceedings or orders; or (vi) fail to pay or the acceleration of other indebtedness. If we fail to file certain periodic reports with the SEC, we will be required to make additional interest payments. As of March 29, 2013, no events of default have occurred.

For financial accounting purposes, the requirements for us to make additional interest payments in the event of early redemption by us and to make additional interest payments in the event that we do not timely file certain periodic reports with the SEC are embedded derivatives. As of March 29, 2013, the fair value of these embedded derivatives has been estimated and is not significant. Our contingent obligation to make an interest make-whole premium payment in the event of an early conversion by the holders of the notes is also an embedded derivative. As of March 29, 2013, the fair value of this contingent obligation has been estimated at $174,000 and is recorded in other liabilities.

We incurred $492,000 of debt issuance costs, which is being amortized to interest expense over the term of the convertible notes through June 15, 2017 using the effective interest method. At March 29, 2013, debt issuance costs of $414,000, net of accumulated amortization, was included in other assets.

Loan and Security Agreement

On February 6, 2012, we entered into a loan and security agreement between us and Silicon Valley Bank, as amended by that certain first amendment to the loan and security agreement entered into on June 12, 2012 and by that certain second amendment to the loan and security agreement entered into on March 8, 2013. The loan and security agreement includes: (i) a term loan facility of $15.0 million; and (ii) a revolving credit facility of up to $20.0 million. As of March 29, 2013, the outstanding balance on the term loan was $15.0 million and the outstanding balance on the revolving credit facility was $13.5 million. The obligations under the loan and security agreement are guaranteed by our material subsidiaries and secured by a security interest in substantially all of our assets and guarantors’ assets, excluding intellectual property.

The principal on the term loan will be payable in quarterly installments beginning on March 31, 2013 and ending on the maturity date of the term loan, February 6, 2017. Quarterly principal payments of $375,000 are due for each quarter during calendar year 2013, $750,000 for each quarter during calendar year 2014, $1.1 million for each quarter during calendar year 2015 and $1.5 million for each quarter during calendar year 2016. Interest on the term loan will be paid quarterly beginning in calendar year 2012. The revolving credit facility also has a maturity date of February 6, 2017. Interest on the revolving credit facility is paid quarterly.

41

The total amount available under the revolving credit facility is $20.0 million. We are eligible to borrow amounts against the revolving credit facility up to the amount allowable by the borrowing base. The borrowing base is calculated on a monthly basis and is based on the amount of our eligible accounts receivable. At March 29, 2013, we had an outstanding revolving credit facility balance of $13.5 million and the amount of the eligible borrowing base was $15.9 million. To the extent that the eligible borrowing base is reduced, we are required to pay down the outstanding revolving credit facility balance to the amount of the eligible borrowing base. During the next 12 months, we expect the borrowing base will be sufficient to maintain borrowings on the revolving credit facility at a minimum of $8.0 million. Consequently, we have classified $8.0 million of the revolving credit facility as a long-term liability.

We have the option to choose, with a few exceptions, whether the term loan facility and revolving credit facility bear interest based on a base rate, which is the prime rate published in The Wall Street Journal, or a LIBOR rate, which has a floor of 0.75%. A base rate facility will bear interest ranging from the base rate plus 1.25% to base rate plus 1.75%. A LIBOR rate facility will bear interest ranging from LIBOR rate plus 3.25% to LIBOR rate plus 3.75%. Both the base rate margin and LIBOR margin vary based upon our liquidity ratio. As of March 29, 2013, the interest rate on both the term loan facility and the revolving credit facility was 4.00%. Total interest expense incurred on the term loan facility and revolving credit facility was $255,000 for the second quarter of fiscal 2013 and $531,000 for the first six months of fiscal 2013.

The revolving credit facility is subject to an unused line of credit fee. This fee is payable quarterly in an amount equal to 0.25%—0.50% of the average daily unused portion of the credit facility. The unused line fee will vary based upon our liquidity ratio.

The loan and security agreement, as amended, requires us to meet certain financial covenants. Beginning in the third quarter of fiscal 2013, we must maintain a minimum cash and cash equivalents balance of $35.0 million with Silicon Valley Bank and a minimum liquidity ratio of 1.40. For each subsequent fiscal quarter, the minimum cash and cash equivalents balance is reduced to $20.0 million. If we fail to maintain the minimum cash and cash equivalents level and liquidity ratio during the third quarter of fiscal 2013, we will be required to maintain a minimum cash and cash equivalents balance of $30.0 million, a minimum liquidity ratio of 1.25 and a minimum adjusted EBITDA of $1.5 million. For each fiscal quarter subsequent to the third quarter of fiscal 2013, if we fail to maintain the minimum $20.0 million cash and cash equivalents balance and the minimum 1.40 liquidity ratio, we will be required to maintain a minimum cash and cash equivalents balance of $15.0 million, a minimum liquidity ratio of 1.25 and a minimum fixed charge coverage ratio of 1.10.

We incurred approximately $537,000 of debt issuance costs related to the loan and security agreement, which is being amortized to interest expense over the term of the facility through February 6, 2017 using the effective interest method. At March 29, 2013, debt issuance costs of approximately $301,000, net of accumulated amortization, were included in other assets.

6.50% Convertible Senior Notes due 2013

On July 30, 2008, we entered into separate exchange agreements with certain holders of our previously outstanding 3.75% convertible senior notes, pursuant to which holders of an aggregate of $15.0 million of the notes agreed to exchange their notes for $15.0 million in aggregate principal amount of a new series of 6.50% convertible senior notes due 2013. The exchange offer closed on August 1, 2008. We paid at the closing an aggregate of approximately $100,000 in accrued and unpaid interest on the 3.75% convertible senior notes that were exchanged for the 6.50% convertible senior notes, as well as approximately $900,000 in transaction fees.

We issued our 6.50% convertible senior notes due in August 2013 pursuant to an indenture, dated as of August 1, 2008, between us and Wells Fargo Bank, N.A., as trustee.

The 6.50% convertible senior notes are unsecured senior indebtedness and bear interest at a rate of 6.50% per annum. Interest is payable on February 1 and August 1 of each year. The notes mature on August 1, 2013. At maturity, we will be required to repay the outstanding principal amount of the notes. At March 29, 2013, $15.0 million in aggregate principal amount of our 6.50% convertible senior notes were outstanding.

42

The 6.50% convertible senior notes are convertible at the option of the holders, at any time on or prior to maturity, into shares of our common stock at a conversion rate equal to approximately $4.74 per share of common stock, which is subject to adjustment in certain circumstances. Upon conversion of the notes, we generally have the right to deliver to the holders thereof, at our option: (i) cash; (ii) shares of our common stock; or (iii) a combination thereof. The initial conversion price of the notes will be adjusted to reflect stock dividends, stock splits, issuances of rights to purchase shares of our common stock, and upon other events. If we undergo certain fundamental changes prior to maturity of the notes, the holders thereof will have the right, at their option, to require us to repurchase for cash some or all of their 6.50% convertible senior notes at a repurchase price equal to 100% of the principal amount of the notes being repurchased, plus accrued and unpaid interest (including additional interest, if any) to, but not including, the repurchase date, or convert the notes into shares of our common stock and, under certain circumstances, receive additional shares of our common stock in the amount provided in the indenture.

For financial accounting purposes, our contingent obligation to issue additional shares or make additional cash payment upon conversion following a fundamental change is an embedded derivative. At March 29, 2013, the liability under the fundamental change adjustment has been recorded at its estimated fair value and is not significant.

If there is an event of default under the 6.50% convertible senior notes, the principal of and premium, if any, on all the notes and the interest accrued thereon may be declared immediately due and payable, subject to certain conditions set forth in the indenture. An event of default under the indenture will occur if we: (i) are delinquent in making certain payments due under the notes; (ii) fail to deliver shares of common stock or cash upon conversion of the notes; (iii) fail to deliver certain required notices under the notes; (iv) fail, following notice, to cure a breach of a covenant under the notes or the indenture; (v) incur certain events of default with respect to other indebtedness; or (vi) are subject to certain bankruptcy proceedings or orders. If we fail to deliver certain SEC reports to the trustee in a timely manner as required by the indenture: (x) the interest rate applicable to the notes during the delinquency will be increased by 0.25% or 0.50%, as applicable (depending on the duration of the delinquency); and (y) if the required reports are not delivered to the trustee within 180 days after their due date under the indenture, a holder of the notes will generally have the right, subject to certain limitations, to require us to repurchase all or any portion of the notes then held by such holder. As of March 29, 2013, no events of default have occurred.

Contractual Obligations

There have been no material changes to the amounts in our contractual obligations as of March 29, 2013, as previously disclosed in our Annual Report on Form 10-K for the fiscal year ended September 28, 2012.

Off-Balance Sheet Arrangements

We have made guarantees and indemnities, under which we may be required to make payments to a guaranteed or indemnified party, in relation to certain transactions. In connection with a June 2003 distribution to stockholders of our former parent company of all outstanding shares of common stock of Mindspeed, we generally assumed responsibility for all contingent liabilities and then-current and future litigation against our former parent company or its subsidiaries related to our business. In connection with certain facility leases, we have indemnified our lessors for certain claims arising from the facility or the lease. We indemnify our directors, officers, employees and agents to the maximum extent permitted under the laws of the State of Delaware. The duration of the guarantees and indemnities varies, and in many cases is indefinite. The majority of our guarantees and indemnities do not provide for any limitation of the maximum potential future payments we could be obligated to make. We have not recorded any liability for these guarantees and indemnities in the accompanying unaudited consolidated condensed balance sheets.

43

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We do not use derivative instruments for speculative or investment purposes.

Interest Rate Risk

Our cash and cash equivalents are not subject to significant interest rate risk. As of March 29, 2013, the carrying value of our cash and cash equivalents approximated fair value.

At March 29, 2013, our debt consisted of a revolving credit facility, a term loan facility and short-term and long-term convertible senior notes. Our revolving credit facility and term loan facility carry variable interest rates and the interest payments are therefore subject to interest rate risk, while the principal is not subject to interest rate risk. We have the option to choose, with a few exceptions, whether the term loan facility and revolving credit facility bear interest based on a base rate, which is the prime rate published in The Wall Street Journal, or a LIBOR rate, which has a floor of 0.75%. If the prime rate or LIBOR rate changed by 1.0%, thereby changing our effective borrowing rate by the same amount, cash interest expense related to the credit facility and term loan facility would change by approximately $300,000, annually. Our convertible senior notes bear interest at a fixed rate of 6.50% and 6.75% per annum. Consequently, our results of operations and cash flows are not subject to any significant interest rate risk relating to our convertible senior notes. The total fair value of the 6.50% and 6.75% convertible senior notes as of March 29, 2013 was $54.3 million and could increase or decrease if interest rates decreases or increase, respectively, which could impact our ability and cost to negotiate a settlement of such notes prior to maturity.

Foreign Exchange Risk

We transact business in various foreign currencies and we face foreign exchange risk on assets and liabilities that are denominated in foreign currencies. Currently, our foreign exchange risks are not hedged; however, from time to time, we may utilize foreign currency forward exchange contracts to hedge a portion of our exposure to foreign exchange risk.

These hedging transactions are intended to offset the gains and losses we experience on foreign currency transactions with gains and losses on the forward contracts, so as to mitigate our overall risk of foreign exchange gains and losses. We do not enter into forward contracts for speculative or trading purposes. At March 29, 2013, we held no foreign currency forward exchange contracts. Based on our overall currency rate exposure at March 29, 2013, a 10% change in currency rates would not have a material effect on our consolidated financial position, results of operations or cash flows.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our chief executive officer and our chief financial officer, we have evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of March 29, 2013. Disclosure controls and procedures are defined under Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the Exchange Act), as controls and other procedures that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within required time periods, and that such information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow for timely decisions regarding required disclosure. Based upon that evaluation, our chief executive officer and our chief financial officer have concluded that, as of March 29, 2013, these disclosure controls and procedures were effective.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting, as defined in Rule 13a-15(f) of the Exchange Act, during the fiscal quarter ended March 29, 2013, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

44

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

In January 2013, Clark Leips, a purported stockholder of ours, filed a lawsuit against us and our board of directors in the United States District Court for the District of Delaware alleging, among other things, that the compensation and management development committee of the board of directors breached its fiduciary duties in each of calendar years 2009, 2010, 2011 and 2012 by approving equity incentive grants for our chief executive officer that exceeded the respective sub-limitations under Section 5 of our 2003 long-term incentives plan for grants to a single participant in any calendar year. The plaintiff also alleged that the disclosures in the proxy statement for our 2013 annual meeting of stockholders are inadequate. The plaintiff seeks, among other things, damages, rescission of the excess grants, disgorgement and attorney’s fees. The plaintiff filed a motion to enjoin our 2013 annual meeting of stockholders until we issued additional disclosures to supplement the proxy statement. On January 22, 2013, we filed a supplement to the proxy statement. The motion for an injunction was then taken off calendar. We and our board of directors have moved to dismiss the complaint. We do not believe the resolution of this matter will result in a material adverse impact on our financial position, results of operations or cash flows.

In addition, we are, from time to time, subject to legal proceedings and claims that arise in the normal course of our business. We do not believe that the ultimate outcome of any such currently pending matters, if any, arising in the normal course of business will have a material adverse effect on our financial position, results of operations or cash flows.

ITEM 1A. RISK FACTORS

We have revised the risk factors that relate to our business, as set forth below. These risks include any material changes to and supersede the risks previously disclosed in Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended September 28, 2012. We encourage investors to review these risk factors, as well as those contained under “Forward-Looking Statements” preceding Part I of this Quarterly Report on Form 10-Q.

Our business, financial condition and operating results can be affected by a number of factors, including those listed below, any one of which could cause our actual results to vary materially from recent results or from our anticipated future results. Any of these risks could also materially and adversely affect our business, financial condition or the price of our common stock or other securities.

Our operating results may be adversely impacted by worldwide political and economic uncertainties and specific conditions in the markets we address, including the cyclical nature of and volatility in the semiconductor industry.

We operate in the semiconductor industry, which is cyclical and subject to rapid change and evolving industry standards. From time to time, the semiconductor industry has experienced significant downturns characterized by decreases in product demand, excess customer inventories and accelerated erosion of prices. The semiconductor industry also periodically experiences increased demand and production capacity constraints, which may affect our ability to ship products. Furthermore, during challenging economic times, our customers and vendors may face issues gaining timely access to sufficient credit, which could impact their ability to make timely payments to us. As a result, we may experience growth patterns that are different than the end demand for products, particularly during periods of high volatility. Accordingly, our operating results may vary significantly as a result of the general conditions in the semiconductor industry, which could cause large fluctuations in our stock price.

We cannot predict the timing, strength or duration of any economic slowdown or the impact it will have on our customers, our vendors or us. The combination of our lengthy sales cycle coupled with challenging macroeconomic conditions could have a compound impact on our business. The impact of market volatility is not limited to revenue, but may also affect our product gross margins and other financial metrics. Any downturns in the semiconductor industry could be severe and prolonged, and any failure of the industry or wired and wireless communications markets to fully recover from downturns could seriously impact our revenue and harm our business, financial condition and results of operations.

45

Our operating results are subject to substantial quarterly and annual fluctuations.

We have incurred significant losses in prior periods. Our net revenue and operating results have fluctuated in the past and may fluctuate in the future and we may incur losses and negative cash flows in future periods. These fluctuations are due to a number of factors, many of which are beyond our control. These factors include, among others:

• changes in end-user demand for the products manufactured and sold by our customers;

• customers could accelerate their demand to earn financial incentives;

• the effects of competitive pricing pressures, including decreases in average selling prices of our products;

• the gain or loss of significant customers;

• market acceptance of our products and our customers’ products;

• our ability to timely develop, introduce, market and support new products and technologies;

• availability and cost of products from our suppliers;

• intellectual property disputes;

• the timing of receipt, reduction or cancellation of significant orders by customers;

• fluctuations in the levels of component inventories held by our customers and changes in our customers’ inventory management practices;

• shifts in our product mix and the effect of maturing products;

• the timing and extent of product development costs;

• new product and technology introductions by us or our competitors;

• fluctuations in manufacturing yields; and

• significant warranty claims, including those not covered by our suppliers.

The foregoing factors are difficult to forecast, and these, as well as other factors, could materially and adversely affect our quarterly or annual operating results.

We have substantial cash requirements to fund our operations, research and development efforts and capital expenditures. Our capital resources are limited and capital needed for our business may not be available when we need it.

We have used significant cash to fund our operating activities. Our principal sources of liquidity are our existing cash balances, cash generated from product sales and our revolving credit facility with Silicon Valley Bank (SVB). We believe that our existing cash balances, along with cash expected to be generated from operations and our revolving credit facility, will be sufficient to fund our operations, research and development efforts, anticipated capital expenditures, working capital and other financing requirements, including principal and interest payments on our debt obligations, for at least the next 12 months. We have completed transactions that involved the issuance of equity and the issuance or incurrence of indebtedness, including credit facilities. Even after completing these transactions, we may need additional capital in the future and may not have access to additional sources of capital on favorable terms or at all. If we raise additional funds through the issuance of equity, equity-based or debt securities, such securities may have rights, preferences or privileges senior to those of our common stock and our stockholders may experience dilution of their ownership interests. In addition, there can be no assurance that we will continue to benefit from the sale or licensing of intellectual property as we have in previous periods.

46

Our review, in consultation with Morgan Stanley, of strategic alternatives potentially available to us may not result in an increase in our stock price or in improvements to our operating results or financial condition. Moreover, the review could distract our management and employees and create substantial uncertainty among customers, suppliers, and other third parties with whom we conduct business, any of which could adversely affect our business, operating results, or financial condition.

On April 30, 2013, we issued a press release announcing that we have engaged Morgan Stanley & Co. LLC to assist us in evaluating various strategic alternatives available to our company. The strategic review will require the expenditure of significant time and resources by our company and management team and may not result in an increase in stockholder value or in improvements to our operating results or financial condition. The strategic review could also distract our executives, employees, and board of directors from other matters relating to the operation of our businesses and affect our ability to attract and retain new executives or key employees. In addition, our announcement of the strategic review may have created and may continue to create uncertainty among current and potential partners, suppliers and customers. In particular, these partners, suppliers and customers could question our commitment to continuing particular product lines or markets or operating as an independent business. As a result of these factors, the announcement could potentially undermine our business and have a material adverse effect on our results of operations or financial condition. In addition, the announcement and subsequent developments could cause increased volatility in our stock price.

Our success depends on our ability to timely develop competitive new products in new markets and keep abreast of the rapid technological changes in our market.

Our operating results will depend largely on our ability to continue to timely introduce new and enhanced semiconductor products in new markets, as well as our ability to keep abreast of rapid technological changes in our markets. Our products could become obsolete sooner than we expect because of faster than anticipated, or unanticipated, changes in one or more of the technologies related to our products. The introduction of new technology representing a substantial advance over current technology could adversely affect demand for our existing products. Currently accepted industry standards are also subject to change, which may also contribute to the obsolescence of our products. If we are unable to develop and introduce new or enhanced products in a timely manner, our business may be adversely affected.

Successful product development and introduction depends on numerous factors, including, among others:

• our ability to anticipate customer and market requirements and changes in technology and industry standards;

• our ability to accurately define new products;

• our ability to complete development of new products, and bring our products to market, on a timely basis;

• our ability to differentiate our products from offerings of our competitors; and

• overall market acceptance of our products.

We may not have sufficient resources to make the substantial investment in research and development in order to develop and bring to market new and enhanced products, particularly if we are required to take further cost reduction actions. Furthermore, we are required to continually evaluate expenditures for planned product development and to choose among alternative technologies based on our expectations of future market growth. We may be unable to timely develop and introduce new or enhanced products, our products may not satisfy customer requirements or achieve market acceptance, or we may be unable to anticipate new industry standards and technological changes. We also may not be able to respond successfully to new product announcements and introductions by competitors.

Research and development projects may experience unanticipated delays related to our internal design efforts. New product development also requires the production of photomask sets and the production and testing of sample devices. In the event we experience delays in obtaining these services from the wafer fabrication and assembly and test vendors on whom we rely, our product introductions may be delayed and our revenue and results of operations may be adversely affected.

47

The price of our common stock may fluctuate significantly.

The price of our common stock is volatile and may fluctuate significantly. There can be no assurance as to the prices at which our common stock will trade or that an active trading market in our common stock will be sustained in the future. The market price at which our common stock trades may be influenced by many factors, including:

• our operating and financial performance and prospects, including our ability to achieve sustained profitability;

• our limited capital resources and availability of capital needed for our business;

• the depth and liquidity of the market for our common stock which can impact, among other things, the volatility of our stock price and the availability of market participants to borrow shares;

• investor perception of us and the industry in which we operate;

• the recently completed acquisition of picoChip may not be accretive and may cause dilution to our earnings per share;

• the level of research coverage of our common stock;

• changes in earnings estimates or buy/sell recommendations by analysts;

• the issuance and sale of additional shares of common stock;

• the recently completed sale and issuance of convertible senior notes;

• limitations placed on our investors by our stockholders rights agreement, which is designed to protect our net operating loss carryforwards;

• general financial and other market conditions; and

• domestic and international economic conditions.

In addition, public stock markets have experienced, and may in the future experience, extreme price and trading volume volatility, particularly in the technology sectors of the market. This volatility has significantly affected the market prices of securities of many technology companies for reasons frequently unrelated to or disproportionately impacted by the operating performance of these companies. These broad market fluctuations may adversely affect the market price of our common stock. If we do not meet the requirements for continued quotation on the Nasdaq Global Select Market (NASDAQ), our common stock could be delisted which would adversely affect the ability of investors to sell shares of our common stock and could otherwise adversely affect our business.

In the second quarter of fiscal 2013, we recorded an impairment charge on the goodwill we obtained through the acquisition of picoChip. Any further impairment in the carrying value of goodwill would negatively impact our consolidated results of operations and/or financial position.

Goodwill is reviewed for impairment on an annual basis in the fourth fiscal quarter or whenever events occur or circumstances change that would more likely than not reduce the fair value of our wireless infrastructure reporting unit below its carrying amount. Fair value is determined based on the discounted cash flows and comparable market values of our reporting unit. If the fair value of the reporting unit is less than its carrying value, the fair value of the implied goodwill is calculated as the difference between the fair value of our reporting unit and the fair value of the underlying assets and liabilities, excluding goodwill. In the event an impairment to goodwill is identified, an immediate charge to earnings in an amount equal to the excess of the carrying value over the implied fair value would be recorded, which would adversely affect our operating results. Determining market values using a discounted cash flow method requires that we make significant estimates and assumptions, including long-term projections of cash flows, market conditions and appropriate market rates. Our judgments are based on historical experience, current market trends and other information. In estimating future cash flows, we rely on internally generated forecasts for operating profits and cash flows, including capital expenditures.

48

Changes in estimates of future cash flows caused by items such as unforeseen events or changes in market conditions could negatively affect our reporting unit’s fair value and result in an impairment charge. Factors that could cause us to change our estimates of future cash flows include a prolonged economic crisis, successful efforts by our competitors to gain market share in our targeted markets, our inability to compete effectively with other semiconductor manufacturers or our inability to maintain price competitiveness. An impairment of a significant portion of our goodwill could materially adversely affect our financial condition and results of operations.

During the second quarter of fiscal 2013, we performed an interim evaluation of goodwill, definite-lived intangibles and indefinite-lived intangibles as we believed there were impairment triggering circumstances which warranted an evaluation. These circumstances consisted of actual and projected decreases in net revenue due to slower than expected deployments of 3G small cell base stations, as compared to prior projections at the time of our last goodwill impairment analysis in July 2012. We may be required to incur significant expenditures to offset the delay in our anticipated increases to revenue.

Given the triggering circumstances, we performed step one of the impairment test for goodwill and determined that the fair value of the wireless infrastructure reporting unit was lower than the carrying value. The failure of step one of the goodwill impairment test triggered a step two impairment analysis, which resulted in an impairment charge of $30.5 million for goodwill related to our wireless infrastructure reporting unit.

Our debt obligations could adversely affect our financial condition.

In recent periods, our debt obligations have increased. As of March 29, 2013, we had $47.0 million in aggregate principal amount of convertible senior notes outstanding. In addition, our loan and security agreement with SVB that was entered into in connection with the picoChip acquisition includes: (i) a term loan facility of $15.0 million; and (ii) a revolving credit facility of up to $20.0 million. As of March 29, 2013, the outstanding balance on the term loan was $15.0 million and the outstanding balance on the revolving credit facility was $13.5 million. Our debt obligations may adversely impact our financial condition. For example, our debt obligations may:

• require us to use a large portion of our cash flow to repay our indebtedness thereunder if we fail to comply with the restrictive financial and operating covenants in the loan and security agreement or if other events of default occur, which may have a material adverse effect on our liquidity and will reduce the availability of our cash flow to fund working capital, capital expenditures, acquisitions or strategic business opportunities, research and development expenditures and other general business activities;

• limit our future ability to raise funds for working capital, capital expenditures, acquisitions or strategic business opportunities, research and development expenditures and other general business activities; and

• contribute to a future downgrade of our credit rating, which could increase future borrowing costs.

Our ability to meet our payment obligations under our debt obligations depends on our ability to generate significant cash flow in the future. We believe our existing and expected cash balances will be sufficient to fund the $15.0 million principal payment of our 6.50% convertible senior notes due in August 2013. However, there can be no assurance that our business will generate cash flow from operations, or that additional capital will be available to us, in an amount sufficient to enable us to meet our payment obligations under our debt obligations and to fund our other liquidity needs. If we are unable to generate sufficient cash flow to service our debt obligations, we may need to refinance or restructure our debt, sell assets, reduce or delay capital investments, or seek to raise additional capital. If we were unable to implement one or more of these alternatives, we may be unable to meet our debt payment obligations.

The loss of one or more key customers or distributors, or the diminished demand for our products from a key customer could significantly reduce our net revenue, gross margin and results of operations.

A relatively small number of end customers and distributors have accounted for a significant portion of our net revenue in any particular period. There has been an increasing trend toward industry consolidation in our markets in recent years, particularly among major network equipment and telecommunications companies. Industry consolidation

49

could decrease the number of significant customers for our products thereby increasing our reliance on key customers. In addition, industry consolidation has generally led, and may continue to lead, to pricing pressures and loss of market share. We have no long-term volume purchase commitments from our key customers. One or more of our key customers or distributors may discontinue operations as a result of consolidation, financial instability, liquidation or otherwise. Reductions, delays and cancellation of orders from our key customers or the loss of one or more key customers could significantly reduce our net revenue and results of operations. We cannot assure you that our current customers will continue to place orders with us, that orders by existing customers will continue at current or historical levels or that we will be able to obtain orders from new customers.

We are entirely dependent upon third parties for the manufacture of our products and are vulnerable to their capacity constraints during times of increasing demand for semiconductor products.

We are entirely dependent upon outside wafer fabrication facilities, known as foundries, for wafer fabrication services. Our principal suppliers of wafer fabrication services are TSMC and Jazz Semiconductor, Inc. We are also dependent upon third parties, including Amkor and ASE, for the assembly and testing of all of our products. Under our fabless business model, our long-term revenue growth is dependent on our ability to obtain sufficient external manufacturing capacity, including wafer production capacity. Periods of upturns in the semiconductor industry may be characterized by rapid increases in demand and a shortage of capacity for wafer fabrication and assembly and test services.

The risks associated with our reliance on third parties for manufacturing services include:

• the lack of assured supply, potential shortages and higher prices;

• the effects of disputes or litigation involving our third-party foundries;

• increased lead times;

• limited control over delivery schedules, manufacturing yields, production costs and product quality; and

• the unavailability of, or delays in obtaining, products or access to key process technologies.

Our standard lead time, or the time required to manufacture our products (including wafer fabrication, assembly and testing), is typically 12 to 16 weeks. During periods of manufacturing capacity shortages, the foundries and other suppliers on whom we rely may devote their limited capacity to fulfill the production requirements of other customers that are larger or better financed than we are, or who have superior contractual rights to enforce the manufacture of their products, including to the exclusion of producing our products.

Additionally, if we are required to seek alternative foundries or assembly and test service providers, we would be subject to longer lead times, indeterminate delivery schedules and increased manufacturing costs, including costs to find and qualify acceptable suppliers. For example, if we choose to use a new foundry, the qualification process may take as long as six months over the standard lead time before we can begin shipping products from the new foundry. Such delays could negatively affect our relationships with our customers.

Wafer fabrication processes are subject to obsolescence, and foundries may discontinue a wafer fabrication process used for certain of our products. In such event, we generally offer our customers a “last-time buy” program to satisfy their anticipated requirements for our products. Any unanticipated discontinuation of a wafer fabrication process on which we rely may adversely affect our revenue and our customer relationships.

The foundries and other suppliers on whom we rely may experience financial difficulties or suffer disruptions in their operations due to causes beyond our control, including deteriorations in general economic conditions, labor strikes, work stoppages, electrical power outages, fire, earthquake, flooding or other natural disasters. Certain of our suppliers’ manufacturing facilities are located near major earthquake fault lines in the Asia-Pacific region and in California. Due to cross dependencies, supply chain disruptions could negatively impact demand of our products, including, for example, if our customers are unable to obtain sufficient supply of other components required for their end product. In the event of a disruption of the operations of one or more of our suppliers, we may not have an alternate source immediately available.

50

Such an event could cause significant delays in shipments until we are able to shift the products from an affected facility or supplier to another facility or supplier. The manufacturing processes we rely on are specialized and are available from a limited number of suppliers. Alternate sources of manufacturing capacity, particularly wafer production capacity, may not be available to us on a timely basis. Even if alternate manufacturing capacity is available, we may not be able to obtain it on favorable terms, or at all. Difficulties or delays in securing an adequate supply of our products on favorable terms, or at all, could impair our ability to meet our customers’ requirements and have a material adverse effect on our operating results.

In addition, the highly complex and technologically demanding nature of semiconductor manufacturing has caused foundries to experience, from time to time, lower than anticipated manufacturing yields, particularly in connection with the introduction of new products and the installation and start-up of new process technologies. Lower than anticipated manufacturing yields may affect our ability to fulfill our customers’ demands for our products on a timely basis. Moreover, lower than anticipated manufacturing yields may adversely affect our gross margin and our results of operations.

We are subject to intense competition.

The communications semiconductor industry in general, and the markets in which we compete in particular, are intensely competitive. We compete worldwide with a number of U.S. and international semiconductor manufacturers that are both larger and smaller than we are in terms of resources and market share. We currently face significant competition in our markets and expect that intense price and product competition will continue. This competition has resulted, and is expected to continue to result, in declining average selling prices for our products.

Many of our current and potential competitors have certain advantages over us, including:

• stronger financial position and liquidity;

• longer, or stronger, presence in key markets;

• greater name recognition;

• more secure supply chain;

• lower cost alternatives to our products;

• access to larger customer bases; and

• significantly greater sales and marketing, manufacturing, distribution, technical and other resources.

As a result, these competitors may be able to adapt more quickly to new or emerging technologies and changes in customer requirements or may be able to devote greater resources to the development, promotion and sale of their products than we can. Moreover, we have incurred substantial operating losses and we may in the future incur losses in future periods. We believe that financial stability of suppliers is an important consideration in our customers’ purchasing decisions. If our OEM customers perceive that we lack adequate financial stability, they may choose semiconductor suppliers that they believe have a stronger financial position or liquidity.

Current and potential competitors also have established or may establish financial or strategic relationships among themselves or with our existing or potential customers, resellers or other third parties. These relationships may affect customers’ purchasing decisions. Accordingly, it is possible that new competitors or alliances among competitors could emerge and rapidly acquire significant market share. We may not be able to compete successfully against current and potential competitors.

We are subject to the risks of doing business internationally.

A significant part of our strategy involves our continued pursuit of growth opportunities in a number of international markets. We market, sell, design and service our products internationally. Products shipped to international destinations,

51

primarily in the Asia-Pacific region and Europe, were approximately 80% of our net revenue for the first six months of fiscal 2013. China is a particularly important international market for us, as approximately 31% of our net revenue for the first six months of fiscal 2013 came from customers in China. In addition, we have design centers, customer support centers and rely on suppliers, located outside the U.S., including foundries and assembly and test service providers located in the Asia-Pacific region. We intend to continue to expand our international business activities and may open other design centers and customer support centers abroad. Our international sales and operations are subject to a number of risks inherent in selling and operating abroad which could adversely impact our international sales and could make our international operations more expensive. These include, but are not limited to, risks regarding:

• currency exchange rate fluctuations;

• local economic and political conditions;

• difficulties in staffing and managing foreign operations;

• potential hostilities and changes in diplomatic and trade relationships;

• tax laws;

• natural disasters, including earthquakes or flooding;

• restrictive governmental actions (such as restrictions on the transfer or repatriation of funds and trade protection measures, including export duties and quotas and customs duties and tariffs);

• changes in legal or regulatory requirements;

• difficulty in obtaining distribution and support;

• disruptions of capital and trading markets;

• acts of terrorism;

• wage inflation;

• greater difficulty in accounts receivable collection and longer payment cycles;

• the laws and policies of the U.S. and other countries affecting trade, foreign investment and loans and import or export requirements, including the Foreign Corrupt Practices Act and similar rules and regulations;

• government export regulations as they apply to the encryption or other features contained in some of our products, which could limit our ability to manufacture the affected products at foreign foundries or ship these products to certain customers;

• tariffs, duties and other import or export restrictions imposed by foreign governments on components that we obtain from non-domestic supplier;

• existing or future environmental laws and regulations governing, among other things, air emissions, wastewater discharges, the contents of our products, the use, handling and disposal of hazardous substances and wastes, soil and groundwater contamination and employee health and safety;

• limitations on our ability under local laws to protect our intellectual property; and

• cultural differences in the conduct of business.

Because most of our international sales are currently denominated in U.S. dollars, our products could become less competitive in international markets if the value of the U.S. dollar increases relative to foreign currencies. As we

52

continue to shift a portion of our operations offshore, more of our expenses are incurred in currencies other than those in which we bill for the related services. An increase in the value of certain currencies, such as the Euro, Japanese yen, Ukrainian hryvnia and Indian rupee, against the U.S. dollar could increase costs of our offshore operations by increasing labor and other costs that are denominated in local currencies.

We may in the future enter into foreign currency forward exchange contracts to mitigate the risk of loss from currency exchange rate fluctuations for foreign currency commitments entered into in the ordinary course of business. We do not enter into foreign currency forward exchange contracts for other purposes. Our financial condition and results of operations could be adversely affected by currency fluctuations.

We may not be able to attract and retain qualified personnel necessary for the design, development, sale and support of our products. Our success could be negatively affected if key personnel leave.

Our future success depends on our ability to attract, retain and motivate qualified personnel, including executive officers and other key management, technical and support personnel. As the source of our technological and product innovations, our key technical personnel represent a significant asset. The competition for such personnel can be intense in the semiconductor industry. We may not be able to attract and retain qualified management and other personnel necessary for the design, development, sale and support of our products.

In periods of poor operating performance, we have experienced, and may experience in the future, particular difficulty attracting and retaining key personnel. If we are not successful in assuring our employees of our financial stability and our prospects for success, our employees may seek other employment, which may materially and adversely affect our business. We intend to continue to expand our international business activities including expansion of design and operations centers abroad and may have difficulty attracting and maintaining international employees. The loss of the services of one or more of our key employees, including Raouf Y. Halim, our chief executive officer, or certain key design and technical personnel, or our inability to attract, retain and motivate qualified personnel could have a material adverse effect on our ability to operate our business.

Some of our engineers are foreign nationals working in the U.S. under work visas. The visas permit qualified foreign nationals working in specialty occupations, such as certain categories of engineers, to reside in the U.S. during their employment. The number of new visas approved each year may be limited and may restrict our ability to hire additional qualified technical employees. In addition, immigration policies are subject to change, and these policies have generally become more stringent since the events of September 11, 2001. Any additional significant changes in immigration laws, rules or regulations may further restrict our ability to retain or hire technical personnel.

Our business is subject to various governmental regulations, and compliance with these regulations may cause us to incur significant expenses. If we fail to maintain compliance with applicable regulations, we may be forced to recall products and cease their manufacture and distribution, and we could be subject to civil or criminal penalties.

Our business is subject to various international and U.S. laws and other legal requirements, including packaging, product content, labor and import/export regulations. These regulations are complex, change frequently and have generally become more stringent over time. We may be required to incur significant costs to comply with these regulations or to remedy violations. Any failure by us to comply with applicable government regulations could result in cessation of our operations or portions of our operations, product recalls or impositions of fines and restrictions on our ability to conduct our operations. In addition, because many of our products are regulated or sold into regulated industries, we must comply with additional regulations in marketing our products.

Our products and operations are also subject to the rules of industrial standards bodies, like the International Standards Organization, as well as regulation by other agencies, such as the U.S. Federal Communications Commission. If we fail to adequately address any of these rules or regulations, our business could be harmed.

For example, the SEC recently adopted a final rule to implement Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, which requires new disclosures concerning the use of conflict minerals, generally tantalum, tin, gold, or tungsten, that originated in the Democratic Republic of the Congo or an adjoining country. These disclosures are required whether or not these products containing conflict minerals are manufactured by us or third parties. Verifying the source of any conflict minerals in our products will create additional costs in order to comply with the new disclosure requirements and we may not be able to certify that the metals in our products are conflict free, which may create issues with our customers. In addition, the new rule may affect the pricing, sourcing and availability of minerals used in the manufacture of our products.

53

We must conform the manufacture and distribution of our products to various laws and adapt to regulatory requirements in all countries as these requirements change. If we fail to comply with these requirements in the manufacture or distribution of our products, we could be required to pay civil penalties, face criminal prosecution and, in some cases, be prohibited from distributing our products in commerce until the products or component substances are brought into compliance.

We may be subject to claims, or we may be required to defend and indemnify customers against claims, of infringement of third-party intellectual property rights or demands that we, or our customers, license third-party technology, which could result in significant expense.

The semiconductor industry is characterized by vigorous protection and pursuit of intellectual property rights. From time to time, third parties have asserted and may in the future assert patent, copyright, trademark and other intellectual property rights against technologies that are important to our business. The resolution or compromise of any litigation or other legal process to enforce such alleged third party rights, including claims arising through our contractual indemnification of our customers, or claims challenging the validity of our patents, regardless of its merit or resolution, could be costly and divert the efforts and attention of our management and technical personnel.

We may not prevail in any such litigation or other legal process or we may compromise or settle such claims because of the complex technical issues and inherent uncertainties in intellectual property disputes and the significant expense in defending such claims. If litigation or other legal process results in adverse rulings, we may be required to:

• pay substantial damages for past, present and future use of the infringing technology;

• cease the manufacture, use or sale of infringing products;

• discontinue the use of infringing technology;

• expend significant resources to develop non-infringing technology;

• pay substantial damages to our customers or end users to discontinue use or replace infringing technology with non-infringing technology;

• license technology from the third party claiming infringement, which license may not be available on commercially reasonable terms, or at all; or

• relinquish intellectual property rights associated with one or more of our patent claims, if such claims are held invalid or otherwise unenforceable.

If we are not successful in protecting our intellectual property rights, it may harm our ability to compete.

We rely primarily on patent, copyright, trademark and trade secret laws, as well as employee and third-party nondisclosure and confidentiality agreements and other methods, to protect our proprietary technologies and processes. We may be required to engage in litigation to enforce or protect our intellectual property rights, which may require us to expend significant resources and to divert the efforts and attention of our management from our business operations; in particular:

• the steps we take to prevent misappropriation or infringement of our intellectual property may not be successful;

• any existing or future patents may be challenged, invalidated or circumvented; or

• the measures described above may not provide meaningful protection.

Despite the preventive measures and precautions that we take, a third party could copy or otherwise obtain and use our technology without authorization, develop similar technology independently or design around our patents. We generally

54

enter into confidentiality agreements with our employees, consultants and strategic partners. We also try to control access to and distribution of our technologies, documentation and other proprietary information. Despite these efforts, internal or external parties may attempt to copy, disclose, obtain or use our products, services or technology without our authorization. Also, former employees may seek employment with our business partners, customers or competitors, and the confidential nature of our proprietary information may not be maintained in the course of such future employment. Further, in some countries outside the U.S., patent protection is not available or not reliably enforced. Some countries that do allow registration of patents do not provide meaningful redress for patent violations. As a result, protecting intellectual property in those countries is difficult and competitors may sell products in those countries that have functions and features that infringe on our intellectual property.

Because of the lengthy sales cycles of many of our products, we may incur significant expenses before we generate any revenue related to those products.

Our customers generally need six months or longer to test and evaluate our products and an additional nine months or more to begin volume production of equipment that incorporates our products. These lengthy periods also increase the possibility that a customer may decide to cancel or change product plans, which could reduce or eliminate sales to that customer. As a result of this lengthy sales cycle, we may incur significant research and development and selling, general and administrative expenses before we generate any revenue from new products. We may never generate the anticipated revenue if our customers cancel or change their product plans as customers may increasingly do if economic conditions continue to deteriorate.

Substantial sales of the shares of our common stock issuable upon conversion of our convertible senior notes or exercise of our outstanding warrant and antidilution and other provisions in our outstanding warrant, or substantial sales of the shares of our common stock issued in connection with the picoChip acquisition could adversely affect our stock price or our ability to raise additional financing in the public capital markets.

At March 29, 2013, we had $47.0 million aggregate principal amount of convertible senior notes outstanding. These notes are convertible at any time, at the option of the holder, into a total of approximately 11.4 million shares of our common stock. In connection with the acquisition of picoChip, we issued an aggregate of approximately 5.2 million shares of our common stock to the stockholders of picoChip. The conversion of the notes and subsequent sale of a substantial number of shares of our common stock related to the notes or the sale of a substantial number of the picoChip acquisition shares could also adversely affect demand for, and the market price of, our common stock. Each of these transactions could adversely affect our ability to raise additional financing by issuing equity or equity-based securities in the public capital markets.

A warrant is outstanding to acquire approximately 6.3 million shares of our common stock at a price of $16.25 per share (adjusted to reflect a change in the number of shares and exercise price, which resulted from the offering of our 6.75% convertible seniors notes completed in the third quarter of fiscal 2012), exercisable through June 27, 2013, representing approximately 10% of our outstanding common stock on a fully diluted basis. The warrant may be transferred or sold in whole or part at any time. If the warrant holder sells the warrant or if it or a transferee of the warrant exercises the warrant and sells a substantial number of shares of our common stock in the future, or if investors perceive that these sales may occur, the market price of our common stock could decline or market demand for our common stock could be sharply reduced.

The warrant contains antidilution provisions that provide for adjustment of the warrant’s exercise price, and the number of shares issuable under the warrant, upon the occurrence of certain events. If we issue, or are deemed to have issued, shares of our common stock, or securities convertible into our common stock, at prices below the current market price of our common stock (as defined in the warrant) at the time of the issuance of such securities, the warrant’s exercise price will be reduced and the number of shares issuable under the warrant will be increased. The amount of such adjustment, if any, will be determined pursuant to a formula specified in the warrant and will depend on the number of shares issued, the offering price and the current market price of our common stock at the time of the issuance of such securities. Adjustments to the warrant pursuant to these antidilution provisions may result in significant dilution to the interests of our existing stockholders and may adversely affect the market price of our common stock. The antidilution provisions may also limit our ability to obtain additional financing on terms favorable to us.

55

Moreover, we may not realize any cash proceeds from the exercise of the warrant. The holder of the warrant may opt for a cashless exercise of all or part of the warrant. In a cashless exercise, the holder of the warrant would make no cash payment to us, and would receive a number of shares of our common stock having an aggregate value equal to the excess of the then-current market price of the shares of our common stock issuable upon exercise of the warrant over the exercise price of the warrant. Such an issuance of common stock would be immediately dilutive to the interests of other stockholders.

Uncertainties involving the ordering and shipment of our products could adversely affect our business.

Our sales are typically made pursuant to individual purchase orders and we generally do not have long-term supply arrangements with our customers. Generally, our customers may cancel orders until 30 days prior to shipment. In addition, we sell a substantial portion of our products through distributors, some of whom have a right to return unsold products to us. Sales to distributors accounted for approximately 70% of our revenue for the second quarter of fiscal 2013.

Because of the significant lead times for wafer fabrication and assembly and test services, we routinely purchase inventory based on estimates of end-market demand for our customers’ products. End-market demand may be subject to dramatic changes and is difficult to predict. End-market demand is highly influenced by the timing and extent of carrier capital expenditures which may decrease due to general economic conditions, and uncertainty, over which we have no control. The difficulty in predicting demand may be compounded when we sell to OEMs indirectly through distributors or contract manufacturers, or both, as our forecasts of demand are then based on estimates provided by multiple parties. In addition, our customers may change their inventory practices on short notice for any reason. The cancellation or deferral of product orders, the return of previously sold products or overproduction due to the failure of anticipated orders to materialize could result in our holding excess or obsolete inventory, which could result in write-downs of inventory. Conversely, if we fail to anticipate inventory needs we may be unable to fulfill demand for our products, resulting in a loss of potential revenue.

If network infrastructure OEMs do not design our products into their equipment, we will be unable to sell those products. Moreover, a design win from a customer does not guarantee future sales to that customer.

Our products are not sold directly to the end-user but are components of other products. As a result, we rely on network infrastructure OEMs to select our products from among alternative offerings to be designed into their equipment. We may be unable to achieve these “design wins.” Without design wins from OEMs, we would be unable to sell our products. Once an OEM designs another supplier’s semiconductors into one of its product platforms, it is more difficult for us to achieve future design wins with that OEM’s product platform because changing suppliers involves significant cost, time, effort and risk for the OEM. Achieving a design win with a customer does not ensure that we will receive significant revenue from that customer, and we may be unable to convert design wins into actual sales. Even after a design win, the customer is not obligated to purchase our products and can choose at any time to stop using our products if, for example, its own products are not commercially successful.

The complexity of our products may lead to errors, defects and/or bugs, any of which could subject us to significant costs or damages and adversely affect market acceptance of our products.

Although we, our customers and our suppliers rigorously test our products, our products are complex and may contain errors, defects or bugs when first introduced or as new versions are released. We have in the past experienced, and may in the future experience, errors, defects and bugs. If any of our products contain production defects or reliability, safety, quality or compatibility problems that are significant to our customers, our reputation may be damaged and customers may be reluctant to buy our products, which could adversely affect our ability to retain existing customers and attract new customers. In addition, these defects or bugs could interrupt or delay sales of affected products to our customers, which could adversely affect our results of operations.

If defects or bugs are discovered after commencement of commercial production of a new product, we may be required to make significant expenditures of capital and other resources to resolve the problems. This could result in significant additional development costs and the diversion of technical and other resources from our other development efforts. We could also incur significant costs to repair or replace defective products, and we could be subject to claims for damages by our customers or others against us. We could also be exposed to product liability claims or indemnification claims by our customers. These costs or damages could have a material adverse effect on our financial condition and results of operations.

56

We may make business acquisitions or investments, which involve significant risk.

In addition to the acquisition of picoChip, we may, from time to time, make acquisitions, enter into alliances or make investments in other businesses to complement our existing product offerings, augment our market coverage or enhance our technological capabilities. However, any such transactions could result in:

• issuances of equity securities dilutive to our existing stockholders;

• substantial cash payments;

• the incurrence of substantial debt and assumption of unknown liabilities;

• large one-time write-offs;

• amortization expenses related to intangible assets;

• a limitation on our ability to use our net operating loss carryforwards;

• the diversion of management’s time and attention from operating our business to acquisition integration challenges;

• adverse tax consequences; and

• the potential loss of key employees, customers and suppliers of the acquired business.

Additionally, in periods subsequent to an acquisition, we must evaluate goodwill and acquisition-related intangible assets for impairment. If such assets are found to be impaired, they will be written down to estimated fair value, with a charge against earnings. As discussed above, a goodwill and asset impairment charge was recorded during the second quarter of fiscal 2013 related to our picoChip acquisition.

Integrating acquired organizations and their products and services may be expensive, time-consuming and a strain on our resources and our relationships with employees, customers and suppliers, and ultimately may not be successful. The benefits or synergies we may expect from the acquisition of complementary or supplementary businesses may not be realized to the extent or in the time frame we initially anticipate. Some of the risks that may affect our ability to successfully integrate acquired companies include those associated with:

• failure to successfully further develop the acquired products or technology;

• conforming the acquired company’s standards, policies, processes, procedures and controls with our operations;

• coordinating new product and process development, especially with respect to highly complex technologies;

• loss of key employees or customers of the acquired company;

• hiring additional management and other critical personnel;

• in the case of foreign acquisitions, the need to integrate operations across different cultures and languages and to address the particular economic, currency, political and regulatory risks associated with specific countries;

• increasing the scope, geographic diversity and complexity of our operations;

57

• consolidation of facilities, integration of the acquired company’s accounting, human resource and other administrative functions and coordination of product, engineering and sales and marketing functions;

• the geographic distance between the companies;

• liability for activities of the acquired company before the acquisition, including patent and trademark infringement claims, violations of laws, commercial disputes, tax liabilities and other known and unknown liabilities; and

• litigation or other claims in connection with the acquired company, including claims for terminated employees, customers, former stockholders or other third parties.

Our ability to utilize our net operating loss carryforwards and certain other tax attributes may be limited.

As of September 28, 2012, we had net operating loss carryforwards of approximately $649.5 million for federal income tax purposes. Furthermore, we acquired additional net operating loss carryforwards upon the acquisition of picoChip. As of December 31, 2011, picoChip had net operating loss carryforwards for U.S. federal and California income tax purposes of $1.5 million each and for U.K. corporation tax purposes of $28.9 million. Under Section 382 of the Internal Revenue Code, if a corporation undergoes an “ownership change,” the corporation’s ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes to offset its post-change income may be significantly limited. An ownership change is generally defined as a greater than 50% change in equity ownership by value over a three-year period. In August 2009, our board of directors adopted a stockholders’ rights agreement that is designed to help preserve our ability to utilize fully certain tax assets primarily associated with net operating loss carryforwards under Section 382 of the Internal Revenue Code. Even with this rights agreement in place, we may experience an ownership change in the future as a result of shifts in our stock ownership, including upon the issuance of our common stock, the exercise of stock options or warrants or as a result of any conversion of our convertible notes into shares of our common stock, among other things. If we were to trigger an ownership change in the future, our ability to use any net operating loss carryforwards existing at that time could be significantly limited.

Our results of operations could vary as a result of the methods, estimates and judgments we use in applying our accounting policies.

The methods, estimates and judgments we use in applying our accounting policies have a significant impact on our results of operations (see “Critical Accounting Policies and Estimates” in Part I, Item 2 of this Quarterly Report on Form 10-Q). Such methods, estimates and judgments are, by their nature, subject to substantial risks, uncertainties and assumptions, and changes in rule making by various regulatory bodies. Factors may arise over time that lead us to change our methods, estimates and judgments. Changes in those methods, estimates and judgments could significantly affect our results of operations.

Provisions in our organizational documents and stockholders rights agreements and Delaware law will make it more difficult for someone to acquire control of us.

Our restated certificate of incorporation, our amended and restated bylaws, our stockholders rights agreements and the Delaware General Corporation Law contain several provisions that would make more difficult an acquisition of control of us in a transaction not approved by our board of directors. Our restated certificate of incorporation and amended and restated bylaws include provisions such as:

• the division of our board of directors into three classes to be elected on a staggered basis, one class each year;

• the exclusive responsibility of the board of directors to fill vacancies on the board of directors;

• the ability of our board of directors to issue shares of our preferred stock in one or more series without further authorization of our stockholders;

• a prohibition on stockholder action by written consent;

58

• a requirement that stockholders provide advance notice of any stockholder nominations of directors or any proposal of new business to be considered at any meeting of stockholders;

• a requirement that a supermajority vote be obtained to remove a director for cause or to amend or repeal certain provisions of our restated certificate of incorporation or amended and restated bylaws;

• elimination of the right of stockholders to call a special meeting of stockholders; and

ITEM 5. OTHER INFORMATION

Restatement of Previously Issued Consolidated Condensed Financial Statements

During the first quarter of fiscal 2013, the Company purchased intellectual property licenses, a portion of which was unpaid as of December 28, 2012. Under ASC 250, Statement of Cash Flows, purchases of assets within investing activities that occur without consuming cash should not be included as direct cash outflows, but should be included in a supplemental schedule or narrative illustrating that these purchases were made as noncash transactions. Subsequent to the issuance of the consolidated condensed financial statements for the three months ended December 28, 2012, the Company identified that it had purchases of licensed intellectual property that had not been paid as of December 28, 2012 and such amounts were included in the statement of cash flow, resulting in an overstatement of the amount of cash generated by operating activities and the total amount of cash used in investing activities. As a result of this error, the Company will restate the consolidated condensed financial statements for the three months ended December 28, 2012 when such amounts appear in its future filings to correct these errors, which management believes are not material to its previously issued consolidated condensed financial statements. The correction had no effect on the Company’s net increase in cash and cash equivalents, statement of operations, statement of comprehensive loss or the carrying amount of any of the Company’s assets or liabilities.
