NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

(in thousands, except per share amounts and percentage data)

1. Organization and Summary of Significant Accounting Policies

Description of Business

MaxLinear, Inc. (the Company) was incorporated in Delaware in September 2003. The Company is a provider of integrated, radio-frequency and mixed-signal semiconductor solutions for broadband communication applications whose customers include module makers, original equipment manufacturers, or OEMs, and original design manufacturers, or ODMs, who incorporate the Company’s products in a wide range of electronic devices including mobile handsets, cable and terrestrial set top boxes, DOCSIS data and voice gateways, televisions, personal computers and netbooks and automotive entertainment applications. The Company is a fabless semiconductor company focusing its resources on the design, sales and marketing of its products.

Basis of Presentation and Principles of Consolidation

The unaudited consolidated financial statements include the accounts of MaxLinear, Inc. and its wholly owned subsidiaries. All intercompany transactions and investments have been eliminated in consolidation.

The functional currency of certain foreign subsidiaries is the local currency. Accordingly, assets and liabilities of these foreign subsidiaries are translated at the current exchange rate at the balance sheet date and historical rates for equity. Revenue and expense components are translated at weighted average exchange rates in effect during the period. Gains and losses resulting from foreign currency translation are included as a component of stockholders’ equity. Foreign currency transaction gains and losses are included in the results of operations and, to date, have not been significant.

The Company has prepared the accompanying unaudited consolidated financial statements in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and disclosures required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments, which include only normal recurring adjustments, considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2012 are not necessarily indicative of the results that may be expected for the year ending December 31, 2012. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes thereto for the year ended December 31, 2011, included in the Annual Report on Form 10-K filed by the Company with the Securities and Exchange Commission (SEC) on March 14, 2012.

Use of Estimates

The preparation of unaudited consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the unaudited consolidated financial statements and accompanying notes of the unaudited consolidated financial statements. Actual results could differ from those estimates.

Revenue Recognition

Revenue is generated from sales of the Company’s integrated circuits. The Company recognizes revenue when all of the following criteria are met: 1) there is persuasive evidence that an arrangement exists, 2) delivery of goods has occurred, 3) the sales price is fixed or determinable and 4) collectibility is reasonably assured. Title to product transfers to customers either when it is shipped to or received by the customer, based on the terms of the specific agreement with the customer.

Revenue is recorded based on the facts at the time of sale. Transactions for which the Company cannot reliably estimate the amount that will ultimately be collected at the time the product has shipped and title has transferred to the customer are deferred until the amount that is probable of collection can be determined. Items that are considered when determining the amounts that will be ultimately collected are: a customer’s overall creditworthiness and payment history; customer rights to return unsold product; customer rights to price protection; customer payment terms conditioned on sale or use of product by the customer; or extended payment terms granted to a customer.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

(in thousands, except per share amounts and percentage data)

A portion of the Company’s revenues are generated from sales made through distributors under agreements allowing for pricing credits and/or stock rotation rights of return. Revenues from the Company’s distributors accounted for 38% and 40% of net revenue for the three and nine months ended September 30, 2012, respectively. Revenues from the Company’s distributors accounted for 71% and 72% of net revenue in the three and nine months ended September 30, 2011, respectively. Pricing credits to the Company’s distributors may result from its price protection and unit rebate provisions, among other factors. These pricing credits and/or stock rotation rights prevent the Company from being able to reliably estimate the final sales price of the inventory sold and the amount of inventory that could be returned pursuant to these agreements. As a result, for sales to distributors, the Company has determined that it does not meet all of the required revenue recognition criteria at the time it delivers its products to distributors as the final sales price is not fixed or determinable. For these distributor transactions, revenue is not recognized until product is shipped to the end customer and the amount that will ultimately be collected is fixed or determinable. Upon shipment of product to these distributors, title to the inventory transfers to the distributor and the distributor is invoiced, generally with 30 day terms. On shipments to the Company’s distributors where revenue is not recognized, the Company records a trade receivable for the selling price as there is a legally enforceable right to payment, relieving the inventory for the carrying value of goods shipped since legal title has passed to the distributor, and records the corresponding gross profit in the consolidated balance sheet as a component of deferred revenue and deferred profit, representing the difference between the receivable recorded and the cost of inventory shipped. Future pricing credits and/or stock rotation rights from the Company’s distributors may result in the realization of a different amount of profit included in the Company’s future consolidated statements of operations than the amount recorded as deferred profit in the Company’s consolidated balance sheets.

The Company records reductions in revenue for estimated pricing adjustments related to price protection and unit rebate agreements with the Company’s end customers in the same period that the related revenue is recorded. Price protection pricing adjustments are recorded at the time of sale as a reduction to revenue and an increase in the Company’s accrued liabilities. The Company may enter into unit rebate agreements with end customers based on volume purchases. The Company estimates that all of the unit rebates will be achieved based on the history of these programs, reduces the average selling price of the product sold under the rebate program and defers revenue for the difference between the amount billed to the customer and the adjusted average selling price. Once the targeted level is achieved, the deferred revenue is recognized as revenue as rebated products are shipped to the end customer. Deferred revenue associated with rebate programs is included in deferred revenue and deferred profit in the consolidated balance sheet.

Stock Repurchase

The Company records the excess of repurchase price over par value to retained earnings upon repurchase and retirement of shares of its Class A common stock and Class B common stock in accordance with the accounting standard for equity.

Recent Accounting Pronouncements

Effective January 1, 2012, the Company adopted the Financial Accounting Standards Board’s, or FASB, updated guidance on fair value measurements that clarifies the application of existing guidance and disclosure requirements, changes certain fair value measurement principles and requires additional disclosures about fair value measurements. The Company’s adoption of the updated guidance did not have a material impact on its consolidated financial statements.

Effective January 1, 2012, the Company adopted the FASB’s new standard regarding the presentation of comprehensive income. The new standard requires the presentation of comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The new standard also requires presentation on the face of the financial statements of reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement where the components of net income and the components of other comprehensive income are presented. The Company’s adoption of the new standard did not have a material impact on its consolidated financial statements.

2. Net Income (Loss) Per Share

Net income (loss) per share is computed as required by the accounting standard for earnings per share, or EPS. Basic EPS is calculated by dividing net income (loss) by the weighted-average number of common shares outstanding for the period, without consideration for common stock equivalents. Diluted EPS is computed by dividing net income (loss) by the weighted-average number of common shares outstanding for the period and the weighted-average number of dilutive common stock equivalents outstanding for the period determined using the treasury-stock method. For purposes of this calculation, common stock options, restricted stock units and restricted stock awards are considered to be common stock equivalents and are only included in the calculation of diluted EPS when their effect is dilutive.

The Company has two classes of stock outstanding, Class A common stock and Class B common stock. The economic rights of the Class A common stock and Class B common stock, including rights in connection with dividends and payments upon a liquidation or merger are identical, and the Class A common stock and Class B common stock will be treated equally, identically and ratably, unless differential treatment is approved by the Class A common stock and Class B common stock, each voting separately as a class. The Company computes basic earnings per share by dividing net income (loss) by the weighted average number of shares of Class A and Class B common stock outstanding during the period. For diluted earnings per share, the Company divides net income (loss) by the sum of the weighted average number of shares of Class A and Class B common stock outstanding and the potential number of shares of dilutive Class A and Class B common stock outstanding during the period.

As of September 30, 2012, the Company held 7 corporate debt securities with an aggregate fair value of $13,090 that were in an unrealized loss position for less than 12 months. The gross unrealized losses of $4 at September 30, 2012 represent temporary impairments on corporate debt securities related to multiple issuers, and were primarily caused by fluctuations in U.S. interest rates. The Company has determined that the gross unrealized losses on these securities at September 30, 2012 are temporary in nature. The Company evaluates securities for other-than-temporary impairment on a quarterly basis. Impairment is evaluated considering numerous factors, and their relative significance varies depending on the situation. Factors considered include the length of time and extent to which fair value has been less than the cost basis, the financial condition and near-term prospects of the issuer, and our intent and ability to hold the security in order to allow for an anticipated recovery in fair value.

All of the Company’s long-term available-for-sale securities were due between one and two years as of September 30, 2012.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

(in thousands, except per share amounts and percentage data)

The fair values of the Company’s financial instruments are the amounts that would be received in an asset sale or paid to transfer a liability in an orderly transaction between unaffiliated market participants and are recorded using a hierarchal disclosure framework based upon the level of subjectivity of the inputs used in measuring assets and liabilities. The levels are described below:

Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities.

Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data.

Level 3: Unobservable inputs are used when little or no market data is available.

The Company classifies its financial instruments within Level 1 or Level 2 of the fair value hierarchy. This is because the Company values financial instruments using quoted market prices or alternate pricing sources and models utilizing market observable inputs. The Company held no Level 3 financial instruments as of September 30, 2012 and December 31, 2011.

The following table presents a summary of the Company’s financial instruments that are measured on a recurring basis:

			Fair Value Measurements at September 30, 2012

5. Stock-Based Compensation and Employee Benefit Plans

Stock-Based Compensation

The Company uses the Black-Scholes valuation model to calculate the fair value of stock options and employee stock purchase rights granted to employees. The Company calculates the fair value of restricted stock units, or RSUs, and restricted stock awards, or RSAs, based on the fair market value of our Class A common stock on the grant date. The weighted-average grant date fair value per share of the RSUs and RSAs granted in the nine months ended September 30, 2012 was $5.87. The weighted-average grant date fair value per share of the RSUs granted in the nine months ended September 30, 2011 was $8.53. No RSAs were granted during the nine months ended September 30, 2011.

The fair values of stock options and employee stock purchase rights were estimated at their respective grant date using the following assumptions:

Stock Options

	Nine Months Ended September 30,
	2012			2011
Weighted-average grant date fair value per share	$	2.37		$	4.26
Risk-free interest rate		0.88	%		2.01	%
Dividend yield		—			—
Expected life (years)		4.84			5.05
Volatility		55.91	%		51.83	%
Employee Stock Purchase Rights
	Nine Months Ended September 30,
	2012			2011
Weighted-average grant date fair value per share	$	1.28		$	2.46
Risk-free interest rate		0.15	%		0.07	%
Dividend yield		—			—
Expected life (years)		0.50			0.50
Volatility		46.60	%		45.70	%

The risk-free interest rate assumption was based on the United States Treasury’s rates for U.S. Treasury zero-coupon bonds with maturities similar to those of the expected term of the award being valued. The assumed dividend yield was based on the Company’s expectation of not paying dividends in the foreseeable future. The weighted-average expected life of options was calculated using the simplified method as prescribed by guidance provided by the SEC. This decision was based on the lack of relevant historical data due to the Company’s limited historical experience. In addition, due to the Company’s limited historical data, the estimated volatility incorporates the historical volatility of comparable companies whose share prices are publicly available.

Exchange Offer

In May 2012, the Company completed an offer to exchange (the “Exchange Offer”) for restricted stock units (RSUs), certain outstanding options to purchase shares of the Company’s Class A common stock and shares of the Company’s Class B common stock. Pursuant to the terms and conditions of the Exchange Offer, the Company accepted for exchange options to purchase 1,327 shares of the Company’s Class A common stock and 591 shares of the Company’s Class B common stock. All surrendered options were cancelled, and immediately thereafter, the Company issued a total of 959 restricted stock units in exchange therefor, pursuant to the terms of the Exchange Offer. The Company accounted for the Exchange Offer as a modification of the original options as required by the accounting standard for stock-based compensation. The total Exchange Offer stock-based compensation is $7.3 million, including the incremental value attributed to the modified options of $1.8 million, which will be recognized over the vesting period of the new RSUs.

Stock Repurchase

In August 2012, the Company’s board of directors and the audit committee of the Company’s board of directors approved the repurchase and retirement of 1,152 shares of the Company’s Class A common stock and the repurchase and retirement of 500 shares of the Company’s Class B common stock. The Company effected the repurchases pursuant to a stock repurchase agreement. The per share repurchase price for both Class A and Class B shares repurchased was the closing price of the Company’s Class A common stock in trading on the New York Stock Exchange on August 21, 2012, the date of the agreement. The aggregate repurchase price was $9.2 million. Other than the transactions disclosed above, the Company’s board of directors has not authorized any stock repurchase program, and the Company has no current plans to effect any open-market purchases of its Class A common stock or other repurchases of its Class B common stock from two of its shareholders.

Employee Benefit Plans

2010 Equity Incentive Plan

The 2010 Plan provides for the grant of incentive stock options, non-statutory stock options, restricted stock awards, restricted stock unit awards, stock appreciation rights, performance-based stock awards, and other forms of equity compensation, or collectively, stock awards. The exercise price for an incentive or a non-statutory stock option cannot be less than 100% of the fair market value of the Company’s Class A common stock on the date of grant. Options granted will generally vest over a four-year period and the term can be from seven to ten years.

On January 1, 2012, 1,329 shares of Class A common stock were automatically added to the shares authorized for issuance under the 2010 Plan pursuant to an “evergreen” provision contained in the 2010 Plan.

2010 Employee Stock Purchase Plan

The 2010 Employee Stock Purchase Plan, or ESPP, is implemented through a series of offerings of purchase rights to eligible employees. Generally, all regular employees, including executive officers, employed by the Company may participate in the ESPP and may contribute up to 15% of their earnings for the purchase of the Company’s common stock under the ESPP. Unless otherwise determined by the Company’s board of directors, Class A common stock will be purchased for accounts of employees participating in the ESPP at a price per share equal to the lower of (a) 85% of the fair market value of a share of the Company’s Class A common stock on the first date of an offering or (b) 85% of the fair market value of a share of the Company’s Class A common stock on the date of purchase.

(in thousands, except per share amounts and percentage data)

On January 1, 2012, 415 shares of Class A common stock were automatically added to the shares authorized for issuance under the ESPP pursuant to an “evergreen” provision contained in the ESPP.

Common Stock

At September 30, 2012, the Company had 500 million authorized shares of Class A common stock and 500 million authorized shares of Class B common stock. Holders of the Company’s Class A and Class B common stock have identical voting rights, except that holders of Class A common stock are entitled to one vote per share and holders of Class B common stock are entitled to ten votes per share with respect to transactions that would result in a change of control of the Company or that relate to the Company’s equity incentive plans. In addition, holders of Class B common stock have the exclusive right to elect two members of the Company’s Board of Directors, each referred to as a Class B Director. The shares of Class B common stock are not publicly traded. Each share of Class B common stock is convertible at any time at the option of the holder into one share of Class A common stock and in most instances automatically converts upon sale or other transfer.

6. Income Taxes

In order to determine the quarterly provision for income taxes, the Company used an estimated annual effective tax rate, which is based on expected annual income and statutory tax rates in the various jurisdictions in which the Company operates. Certain significant or unusual items are separately recognized in the quarter during which they occur and can be a source of variability in the effective tax rates from quarter to quarter.

The Company recorded a provision for income taxes of $44 and $235 for the three and nine months ended September 30, 2012, respectively. The Company recorded a provision for income taxes of $8,227 and $6,710 for the three and nine months ended September 30, 2011, respectively. The provision for income taxes for the three and nine months ended September 30, 2012 primarily relates to income tax in certain foreign jurisdictions. The provision for income taxes for the three and nine months ended September 30, 2011 primarily relates to the establishment of a valuation allowance against the Company’s net federal deferred tax asset in the third quarter of 2011.

During the nine months ended September 30, 2012, the Company’s unrecognized tax benefits increased by $151. The Company does not anticipate its unrecognized tax benefits will change significantly over the next 12 months. There were no accrued interest and penalties associated with uncertain tax positions as of September 30, 2012.

7. Commitments and Contingencies

Silicon Labs Litigation

On May 13, 2012, the Company filed a declaratory judgment complaint in United States District Court for the Southern District of California against Silicon Laboratories Inc., or Silicon Labs, as defendant seeking an order that the Company’s CMOS hybrid tuner products, such as the MxL301 and MxL601, do not infringe nineteen (19) patents owned by Silicon Labs. The declaratory judgment complaint further seeks a ruling that the defendant’s patents are invalid. Silicon Labs has filed counterclaims for infringement on five (5) of the nineteen (19) patents and one (1) additional Silicon Labs patent. On September 13, 2012, Silicon Labs filed a motion for preliminary injunction requesting an injunction on the Company’s MxL601 product based upon alleged infringement of U.S. Patent No. 7,200,364. The hearing on the preliminary injunction motion is set for November 2, 2012. The Court has scheduled a claims construction hearing for April 19, 2013 and scheduled trial to commence on February 11, 2014.

On July 17, 2012, Silicon Labs filed a complaint for patent infringement against the Company in United States District Court for the Southern District of California. The Silicon Labs complaint asserts that a wide range of the Company’s products infringe a single Silicon Labs patent, U.S. Patent No. 7,035,607, or the ‘607 patent. The ‘607 patent is related to several of the nineteen (19) patents on which the Company filed a declaratory judgment action against Silicon Labs. The Silicon Labs complaint seeks damages and injunctive relief against the Company’s products. The Company has filed counterclaims for infringement on three (3) patents owned by the Company – United States Patent Nos. 7,362,178; 8,198,940; and 7,778,613. Silicon Labs has filed a motion to dismiss or transfer the Company’s counterclaims for infringement to the United States District Court for the Western District of Texas. The Court denied that motion. No trial date has been set.

On July 30, 2012, Silicon Labs filed a declaratory judgment complaint in United States District Court for the Western District of Texas against the Company seeking an order that Silicon Labs’ products do not infringe the three (3) patents owned by the Company asserted as counterclaims in the second Southern District of California action. The declaratory judgment complaint further seeks a ruling that the patents are invalid. The Company has filed a motion to dismiss for lack of personal jurisdiction, and the Court has granted limited jurisdictional discovery related to the issue. No trial date has been set.

The Company has not recorded any accrual for loss contingencies associated with Silicon Labs litigation; determined that an unfavorable outcome is probable or reasonably possible; or determined that the amount or range of any possible loss is reasonably estimable.

Export Compliance Matter

As noted in the Company’s Current Report on Form 8-K filed on February 7, 2012, in the first quarter of 2012, the Company determined that it may have taken actions that could constitute facilitation (within the meaning of applicable sanctions and export control laws) of shipments of foreign produced products to Iran or taken other actions that may be in violation of U.S. export control and economic sanctions laws. Specifically, certain of the Company’s tuner products, which are foreign produced and not subject to U.S. export controls, were included in set-top converter boxes produced by set-top box manufacturers in Asia to permit conversion of digital television signals to analog signals in international markets, including Iran, using the DVB-T, or Digital Video Broadcasting – Terrestrial, broadcast standard. The DVB-T standard is used in most of Europe, Asia (excluding China), Australia, and Africa as well as in parts of the Middle East, including Iran. While the underlying shipment of the Company’s tuners into Iran by foreign manufacturers of these set-top boxes may have been lawful, the Company may have violated applicable sanctions and export control laws without the proper U.S. Government authorization.

The Company initially identified these potential violations internally, rather than as a result of a third-party audit or government investigation, and upon learning of these potential violations, the Company’s audit committee promptly retained outside counsel to conduct a review of the Company’s sanctions and export control compliance. On February 7, 2012, the Company made voluntary initial filings with the Office of Foreign Assets Control of the United States Department of the Treasury, or OFAC, and with the Bureau of Industry and Security of the United States Department of Commerce, or BIS, notifying these regulatory agencies that the Company was conducting a review of export control matters and that the Company would submit any supplemental voluntary self-disclosures once the Company’s internal review was complete. The initial stage of the review was concluded in March 2012. Subsequently, the Company also learned that the Company was not in full compliance with BIS’s deemed export rule which requires, in some circumstances, that the companies obtain a deemed export license from BIS for employment of certain foreign nationals even if, as was the Company’s situation, the Company had obtained an H1-B visa prior to employing the individual. The Company has now applied for such license with respect to the subject employee.

In connection with its March 2012 review, the Company’s audit committee determined that the Company’s management team lacked sufficient familiarity with and understanding of export control and sanctions laws and their applicability to the Company’s products and services. The Company’s audit committee concluded that the Company’s management team did not intentionally or knowingly violate applicable sanctions and export control laws.

The Company submitted final voluntary disclosures to OFAC on June 1, 2012 and BIS on June 15, 2012 and July 11, 2012. On September 27, 2012, OFAC closed out the Company’s Voluntary Self Disclosure with the issuance of a cautionary letter, and no monetary or other penalty was imposed against the Company. The BIS Voluntary Self Disclosure remains pending and the Company informed BIS that OFAC closed out its case with a cautionary letter.

Penalties and potential criminal enforcement actions could be imposed against the Company and/or the Company’s management and certain of the Company’s employees. The Company cannot predict when BIS will complete its review of the Company’s submissions, and resolution of the BIS matter could take substantial time and require substantial expenditure and management resources, either of which could be harmful to the Company’s business and operating results.

Any fines that BIS may impose on the Company could be material to the Company’s operating results in the period in which they are imposed and could have a material adverse effect on the Company’s financial condition. The maximum civil monetary penalty for each violation is up to $250 or twice the value of the transaction, whichever is greater. In the three and nine months ended September 30, 2012, the Company reduced its previously recorded OFAC penalties and fines by $625 reflected in selling, general, and administrative expense. Based upon facts known to the Company to date, the Company has retained a total provision of $250 for this export compliance matter, representing management’s estimated exposure for potential BIS fines in accordance with applicable accounting literature. Should additional facts be discovered in the future and/or should actual fines or other penalties differ from the Company’s estimates, its business, operating results, and financial condition could be materially and negatively affected. In that regard, the Company cannot guarantee that BIS will agree with its assessments of the quantity and nature of the potential violations. As a result, BIS could seek to impose higher fines and penalties than those the Company has estimated to date, and the Company could incur significant additional legal expenses in response. As a result of increased awareness relative to U.S. export control and economic sanction laws relating to the sale of the Company’s products, the Company has implemented additional export control compliance management oversight and has undertaken remedial measures to reduce the risk of similar events occurring in the future.

We do not assume any obligation to update any forward-looking statements.

Overview

We are a provider of integrated, radio-frequency and mixed-signal semiconductor solutions for broadband communications applications. Our high performance radio-frequency, or RF, receiver products capture and process digital and analog broadband signals to be decoded for various applications. These products include both RF receivers and RF receiver systems-on-chip, or SoCs, which incorporate our highly integrated radio system architecture and the functionality necessary to demodulate broadband signals. Our current products enable the display of broadband video content in a wide range of electronic devices, including cable and terrestrial set top boxes, DOCSIS data and voice gateways, digital televisions, mobile handsets, personal computers, netbooks and in-vehicle entertainment devices.

Our net revenue has grown from approximately $0.6 million in fiscal 2006 to $71.9 million in fiscal 2011. In the nine months ended September 30, 2012 and 2011, respectively, our net revenue was derived from sales of global digital RF receiver products for digital set top box applications, automotive navigation displays, mobile handsets, cable modems and gateways and digital televisions. Our ability to achieve revenue growth in the future will depend, among other factors, on our ability to further penetrate existing markets; our ability to expand our target addressable markets by developing new and innovative products; and our ability to obtain design wins with device manufacturers, in particular manufacturers of set top boxes and cable modems and gateways for the cable industry.

Substantially all of our sales have been to customers outside the United States. Sales in Asia accounted for 94% and 90% of net revenue in the three and nine months ended September 30, 2012, respectively; and 92% and 89% of net revenue in the three and nine months ended September 30, 2011, respectively. A significant but declining portion of these sales in Asia are through distributors. Although we actually sell the products to, and are paid by, the distributors, we refer to end customers as our customers. Because many of our end customers or their ODM manufacturers are located in Asia, we anticipate that a majority of our revenue will continue to come from sales to that region. Although a large percentage of our sales are made in Asia, we believe that a significant number of the systems designed by these customers and incorporating our semiconductor products are then sold outside Asia. For example, we believe revenue generated from sales of our digital terrestrial set top box products during the three and nine months ended September 30, 2012 and 2011 related principally to sales to Asian set top box manufacturers delivering products into European markets. Similarly, revenue generated from sales of our cable modem products during the three and nine months ended September 30, 2012 and 2011 related principally to sales to Asian ODM’s and contract manufacturers delivering products into European and North American markets. To date, all of our sales have been denominated in United States dollars.

A significant portion of our net revenue has historically been generated by a limited number of customers. In the three months ended September 30, 2012, one of our customers accounted for 21%, respectively, of our net revenue, and our ten largest customers collectively accounted for 60% of our net revenue. For the nine months ended September 30, 2012, one customer accounted for 18% of our net revenue, and our ten largest customers accounted for 58% of our net revenue. In the three months ended September 30, 2011, two of our customers accounted for 12% and 11%, respectively, of our net revenue, and our ten largest customers collectively accounted for 64% of our net revenue. In the nine months ended September 30, 2011, one customer accounted for 16% of our net revenue, and our ten largest customers collectively accounted for 57% of our net revenue. For certain customers, we sell multiple products into disparate end user applications such as modules for televisions, in-vehicle or automotive applications and mobile handsets.

16

Our business depends on winning competitive bid selection processes, known as design wins, to develop semiconductors for use in our customers’ products. These selection processes are typically lengthy, and as a result, our sales cycles will vary based on the specific market served, whether the design win is with an existing or a new customer and whether our product being designed in our customer’s device is a first generation or subsequent generation product. Our customers’ products can be complex and, if our engagement results in a design win, can require significant time to define, design and result in volume production. Because the sales cycle for our products is long, we can incur significant design and development expenditures in circumstances where we do not ultimately recognize any revenue. We do not have any long-term purchase commitments with any of our customers, all of whom purchase our products on a purchase order basis. Once one of our products is incorporated into a customer’s design, however, we believe that our product is likely to remain a component of the customer’s product for its life cycle because of the time and expense associated with redesigning the product or substituting an alternative chip. Product life cycles in our target markets will vary by application. For example, in the digital set top box market a design-in can have a product life cycle of 18 to 24 months. In the automotive sector, the product life cycle of a design-in can range from 36 to 60 months. In the mobile television sector, the product life cycle of a design-in can range from 12 to 36 months.

Critical Accounting Policies and Estimates

Management’s discussion and analysis of our financial condition and results of operations are based upon our financial statements which are prepared in accordance with accounting principles that are generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities, related disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. We continually evaluate our estimates and judgments, the most critical of which are those related to revenue recognition, allowance for doubtful accounts, inventory valuation, income taxes and stock-based compensation. We base our estimates and judgments on historical experience and other factors that we believe to be reasonable under the circumstances. Materially different results can occur as circumstances change and additional information becomes known.

There were no significant changes during the quarter ended September 30, 2012 to the items that we disclosed as our critical accounting policies and estimates in Note 1 to our consolidated financial statements for the year ended December 31, 2011 contained in the Annual Report on Form 10-K filed with the SEC on March 14, 2012.

Results of Operations

The following describes the line items set forth in our consolidated statements of operations.

Net Revenue. Net revenue is generated from sales of our RF receivers and RF receiver SoCs. A significant but declining portion of our end customers purchase products indirectly from us through distributors. Although we actually sell the products to, and are paid by, the distributors, we refer to these end customers as our customers.

Cost of Net Revenue. Cost of net revenue includes the cost of finished silicon wafers processed by third-party foundries; costs associated with our outsourced packaging and assembly, test and shipping; costs of personnel, including stock-based compensation, and equipment associated with manufacturing support, logistics and quality assurance; amortization of certain production mask costs; cost of production load boards and sockets; and an allocated portion of our occupancy costs.

Research and Development. Research and development expense includes personnel-related expenses, including stock-based compensation, new product engineering mask costs, prototype integrated circuit packaging and test costs, computer-aided design software license costs, intellectual property license costs, reference design development costs, development testing and evaluation costs, depreciation expense and allocated occupancy costs. Research and development activities include the design of new products, refinement of existing products and design of test methodologies to ensure compliance with required specifications. All research and development costs are expensed as incurred.

Selling, General and Administrative. Selling, general and administrative expense includes personnel-related expenses, including stock-based compensation, distributor and other third-party sales commissions, field application engineering support, travel costs, professional and consulting fees, legal fees, depreciation expense and allocated occupancy costs.

Interest Income. Interest income consists of interest earned on our cash, cash equivalents and investment balances.

Interest Expense. Interest expense consists primarily of imputed interest on i) the purchase of licensed technology and ii) property and equipment capital leases.

17

Other Income (Expense). Other income (expense) generally consists of income (expense) generated from non-operating transactions.

Provision (Benefit) for Income Taxes. We make certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments occur in the calculation of certain tax assets and liabilities, which arise from differences in the timing of recognition of revenue and expenses for tax and financial statement purposes and the realizability of assets in future years.

Net revenue	$	27,795	$	17,639		58	%	$	72,898	$	52,641		38	%

The increase in net revenue in the three months ended September 30, 2012, as compared to the three months ended September 30, 2011, was primarily due to an increase in sales revenue from cable products of $11.8 million, offset by a decrease in revenue derived from terrestrial products of $1.6 million, with terrestrial declines primarily attributable to automotive in-cabin applications and TV applications of $2.4 million, offset somewhat by growth in terrestrial set-top box and other smaller terrestrial applications. The increase in net revenue in the nine months ended September 30, 2012, as compared to the nine months ended September 30, 2011 was primarily due to a significant increase in shipments of products used in cable applications of approximately $29.8 million, offset by a decrease in revenue from automotive and TV applications of $4.6 million and $3.7 million, respectively. The demand for our terrestrial and cable products will depend on several factors, including the rate of worldwide transition from analog-to-digital terrestrial and cable broadcast, and the growth in demand, if any, for high speed broadband connectivity and multimedia content and services.

% of net revenue		63%		64%				62%		64%

The decreases in the gross profit percentage were primarily due to average selling prices of several products declining faster than their average manufacturing costs. Also negatively influencing gross margin was a lower mix of certain high margin Japanese end-market terrestrial product shipments, specifically mobile handset, automotive, and digital TV applications, that were replaced by global shipments of lower margin hybrid TV solutions. We currently expect that gross profit percentage will fluctuate in the future, from quarter-to-quarter, based on changes in product mix, average selling prices, and average manufacturing costs.

Research and Development

	Three Months Ended September 30,									Nine Months Ended September 30,
	2012			2011			% Change			2012			2011			% Change
	(dollars in thousands)									(dollars in thousands)
Research and development	$	10,855		$	9,456			15	%	$	33,758		$	29,977			13	%
% of net revenue		39	%		54	%					46	%		57	%

The increase for the three months ended September 30, 2012 was due to increases in payroll-related spending. The increase for the nine months ended September 30, 2012 was primarily due to a combination of payroll-related items, prototyping and mask expenses, partially offset by a reduction in spending on embedded intellectual property IP licensing. Payroll-related expenses (including stock-based compensation) increased $1.7 million and $5.9 million for the three and nine months ended September 30, 2012, respectively. These increases are primarily due to increases in our average full-time-equivalent headcount compared to the same three and nine month periods of the prior year and expenses related to the 2012 employee bonus plan and increases in employee healthcare costs. Also contributing to the increase for the nine months ended September 30, 2012 compared to the same period in the prior year were additional expenses related to our first 40 nanometer mask set, and computer-aided design and related software licensing costs. In the past, we have entered into technology license agreements based on management review and determinations concerning market opportunities. We cannot predict whether we will enter into more of these types of licenses or the magnitude or timing of any such license agreements. Absent these types of licensing events, we expect our research and development expenses to increase as we continue to focus on expanding our product portfolio and enhancing existing products.

Selling, General and Administrative

	Three Months Ended September 30,						Nine Months Ended September 30,
	2012		2011		% Change		2012		2011		% Change
	(dollars in thousands)						(dollars in thousands)
Selling, general and administrative	$	6,167	$	5,033		23%	$	19,750	$	14,329		38%
% of net revenue		22%		28%				27%		27%

The increases in the three and nine months ended September 30, 2012 were primarily attributable to increases in payroll-related spending and consulting expenses, and significant incremental legal expenses related to a previously disclosed export compliance matter as well as our initiation and defense of litigation with Silicon Laboratories, or Silicon Labs, offset by a $0.6 million reduction in the estimated exposure for fines related to the export compliance matter. Payroll-related expenses (including stock-based compensation) increased $0.8 million and $2.8 million for the three and nine months ended September 30, 2012, respectively. These increases are primarily due to increases in our average full-time-equivalent headcount compared to the same three and nine month periods of the prior year and an increase in new hire cash bonuses and expenses related to the 2012 employee bonus plan and increases in employee healthcare costs. We expect selling, general and administrative expenses to increase in the future as we expand our sales and marketing organization to enable expansion into existing and new markets, as we continue to build our international administrative infrastructure. Future selling, general, and administrative expenses could also be affected by legal expenses associated with the lawsuit filed against Silicon Labs and related actions. We have not recorded any accrual for loss contingencies associated with Silicon Labs litigation; determined that an unfavorable outcome is probable or reasonably possible; or determined that the amount or range of any possible loss is reasonably estimable.

Interest and Other Income (Expense)

	Three Months Ended September 30,						Nine Months Ended September 30,
	2012			2011			2012			2011
Interest income	$	74		$	63		$	221		$	234
Interest expense		(11	)		(32	)		(45	)		(38	)
Other expense, net		(14	)		(35	)		(109	)		(110	)

Interest income increased in the three months ended September 30, 2012 compared to the three months ended September 30, 2011 due to higher investment balances, principally due to a change in the composition of cash equivalents and investments. Interest income decreased in the nine months ended September 30, 2012 compared to the nine months ended September 30, 2011 due to lower cash and investment balances.

Interest expense decreased in the three months ended September 30, 2012 compared to the three months ended September 30, 2011, due to lower outstanding debt balances. Interest expense increased in the nine months ended September 30, 2012 compared to the nine months ended September 30, 2011 related to an accrued technology license agreement with extended payment terms.

Other expense, net decreased in the three months ended September 30, 2012 compared to the three months ended September 30, 2011 due to decreased write downs of long-lived assets. Other expense, net decreased in the nine months ended September 30, 2012 compared to the nine months ended September 30, 2011 due to other income from a property tax refund.

Provision (Benefit) for Income Taxes

	Three Months Ended September 30,				Nine Months Ended September 30,
	2012		2011		2012		2011
Provision for income taxes	$	44	$	8,227	$	235	$	6,710

The provision for income taxes for the three months ended September 30, 2012 was $44 or approximately 8.9% of pre-tax income compared to a provision for income taxes of $8.2 million for the three months ended September 30, 2011. The provision for income taxes for the nine months ended September 30, 2012 was $235 or approximately (2.8)% of pre-tax loss compared to $6.7 million for the nine months ended September 30, 2011. The provision for income taxes for the three and nine months ended September 30, 2012 primarily relates to income tax in foreign jurisdictions. The provision for income taxes for the three and nine months ended September 30, 2011 was primarily related to the establishment of a valuation allowance against our net federal deferred tax asset in the third quarter of 2011. We continue to maintain a valuation allowance to offset the federal and California deferred tax assets as realization of such assets does not meet the more-likely-than-not threshold required under accounting guidelines. We will continue to assess the need for a valuation allowance on the deferred tax assets by evaluating positive and negative evidence that may exist. Until such time that we remove the valuation allowance against our federal and California deferred tax assets, our provision for income taxes will primarily consist of taxes associated with our foreign subsidiaries.

Liquidity and Capital Resources

As of September 30, 2012, we had cash and cash equivalents of $26.6 million, short- and long-term investments of $53.4 million, and net accounts receivable of $16.3 million.

Following is a summary of our working capital and cash and cash equivalents as of September 30, 2012 and December 31, 2011:

	September 30,		December 31,
	2012		2011
	(in thousands)
Working capital	$	74,952	$	76,585
Cash and cash equivalents		26,634		28,026

Stock Repurchase

In August 2012, our board of directors and the audit committee of our board of directors approved the repurchase and retirement of 1,152 shares of our Class A common stock and the repurchase and retirement of 500 shares of our Class B common stock. We effected the repurchases pursuant to a stock repurchase agreement. The per share repurchase price for both Class A and Class B shares repurchased was the closing price of our Class A common stock in trading on the New York Stock Exchange on August 21, 2012, the date of the agreement. The aggregate repurchase price was $9.2 million. Other than the transactions disclosed above, our board of directors has not authorized any stock repurchase program, and we have no current plans to effect any open-market purchases of our Class A common stock or other repurchases of our Class B common stock from two of our shareholders.

Cash Flows from Operating Activities

Net cash provided by operating activities was $6.2 million for the nine months ended September 30, 2012. Net cash provided by operating activities primarily consisted of $4.3 million in changes in operating assets and liabilities and $10.6 million in non-cash operating expenses, partially offset by a net loss of $8.7 million. Non-cash items included in net loss for the nine months ended September 30, 2012 included depreciation and amortization expense of $2.6 million, amortization of investment premiums, net of $0.8 million and stock-based compensation of $7.2 million. Included in changes in operating assets and liabilities were incremental accruals related to legal expenses for our Silicon Laboratories, or Silicon Labs, litigation as well as a reduction in the accrual related to estimated fines and penalties related to a previously disclosed export compliance matter. Net cash used in operating activities was $5.2 million for the nine months ended September 30, 2011. Net cash used in operating activities primarily consisted of a net loss of $17.3 million and $2.9 million in changes in operating assets and liabilities, offset in part by $15.0 million in non-cash operating expenses. Non-cash items included in net loss for the nine months ended September 30, 2011 included depreciation and amortization expense of $2.3 million, amortization of investment premiums, net of $0.9 million, stock-based compensation of $5.2 million and a decrease in deferred income taxes of $6.6 million.

Cash Flows from Investing Activities

Net cash provided by investing activities was $0.1 million for the nine months ended September 30, 2012. Net cash provided by investing activities consisted of $69.9 million in maturities of securities, partially offset by $66.4 million in purchases of securities, $3.0 million in purchases of property and equipment and $0.4 million in purchases of intangibles. Net cash provided by investing activities was $25.4 million for the nine months ended September 30, 2011. Net cash provided by investing activities consisted of $98.6 million in maturities of securities, partially offset by $71.0 million in purchases of securities and $2.2 million in purchases of property and equipment.

Cash Flows from Financing Activities

Net cash used in financing activities was $7.7 million for the nine months ended September 30, 2012. Net cash used in financing activities consisted primarily of repurchases of common stock of $9.2 million, partially offset by net proceeds from issuance of common stock of $1.6 million primarily related to our employee stock purchase plan. Net cash provided by financing activities was $1.7 million for the nine months ended September 30, 2011. Net cash provided by financing activities consisted primarily of proceeds from issuance of common stock of $1.8 million offset by payments on capital leases of $0.1 million.

We believe that our $26.6 million of cash and cash equivalents and $53.4 million in short- and long-term investments at September 30, 2012 will be sufficient to fund our projected operating requirements for at least the next twelve months. However, we may need to raise additional capital or incur additional indebtedness to continue to fund our operations in the future. Our future capital requirements will depend on many factors, including our rate of revenue growth, the expansion of our engineering, sales and marketing activities, the timing and extent of our expansion into new territories, the timing of introductions of new products and enhancements to existing products, the continuing market acceptance of our products and potential material investments in, or acquisitions of, complementary businesses, services or technologies. Additional funds may not be available on terms favorable to us or at all. If we are unable to raise additional funds when needed, we may not be able to sustain our operations.

Warranties and Indemnifications

In connection with the sale of products in the ordinary course of business, we often make representations affirming, among other things, that our products do not infringe on the intellectual property rights of others, and agree to indemnify customers against third-party claims for such infringement. Further, our certificate of incorporation and bylaws require us to indemnify our officers and directors against any action that may arise out of their services in that capacity, and we have also entered into indemnification agreements with respect to all of our directors and certain controlling persons. As of September 30, 2012, we incurred expenses of $0.3 million under such provisions related to a previously disclosed export compliance matter.

Off-Balance Sheet Arrangements

As part of our ongoing business, we do not participate in transactions that generate relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, or SPEs, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As of September 30, 2012, we were not involved in any unconsolidated SPE transactions.

21

Contractual Obligations

There have been no material changes, outside of the ordinary course of business, in our outstanding contractual obligations from those disclosed within “Management’s Discussion and Analysis of Financial Condition and Results of Operations”, as contained in our Annual Report on Form 10-K filed by the Company with the SEC on March 14, 2012.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Foreign Currency Risk

To date, our international customer and vendor agreements have been denominated almost exclusively in United States dollars. Accordingly, we have limited exposure to foreign currency exchange rates and do not enter into foreign currency hedging transactions. The functional currency of certain foreign subsidiaries is the local currency. Accordingly, the effects of exchange rate fluctuations on the net assets of these foreign subsidiaries’ operations are accounted for as translation gains or losses in accumulated other comprehensive income within stockholders’ equity. We do not believe that a change of 10% in such foreign currency exchange rates would have a material impact on our financial position or results of operations.

Interest Rate Risk

We had cash of $26.6 million at September 30, 2012, which was held for working capital purposes. We do not enter into investments for trading or speculative purposes. We do not believe that we have any material exposure to changes in the fair value of these investments as a result of changes in interest rates due to their short-term nature. Declines in interest rates, however, will reduce future investment income.

Investments Risk

Our investments, consisting of U.S. Treasury and agency obligations and corporate notes and bonds, are stated at cost, adjusted for amortization of premiums and discounts to maturity. In the event that there are differences between fair value and cost in any of our available-for-sale securities, unrealized gains and losses on these investments are reported as a separate component of accumulated other comprehensive income (loss).

Investments in fixed rate interest earning instruments carry a degree of interest rate risk. Fixed rate securities may have their market value adversely impacted due to rising interest rates. Due in part to these factors, our future investment income may fall short of expectations due to changes in interest rates.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our periodic reports filed with the SEC is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow for timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and no evaluation of controls and procedures can provide absolute assurance that all control issues and instances of fraud, if any, within a company have been detected. Management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

As required by Rule 13a-15(b) of the Securities Exchange Act of 1934, as amended, or the Exchange Act, prior to filing this Quarterly Report, we carried out an evaluation, under the supervision and with the participation of our management, including our principal executive officer, principal financial officer and principal accounting officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act) as of the end of the period covered by this Quarterly Report. Based on their evaluation, our principal executive officer, principal financial officer and principal accounting officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this Quarterly Report.

22

Changes in Internal Control over Financial Reporting

An evaluation was performed under the supervision and with the participation of our management, including our principal executive officer, principal financial officer and principal accounting officer, to determine whether any change in our internal control over financial reporting occurred during the fiscal quarter ended September 30, 2012 that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. We did not identify any change in our internal control over financial reporting that occurred during the fiscal quarter ended September 30, 2012 that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

Silicon Labs Litigation

On May 13, 2012, we filed a declaratory judgment complaint in United States District Court for the Southern District of California against Silicon Laboratories Inc. (Silicon Labs), as defendant seeking an order that our CMOS hybrid tuner products, such as the MxL301 and MxL601, do not infringe nineteen (19) patents owned by Silicon Labs. The declaratory judgment complaint further seeks a ruling that the defendant’s patents are invalid. Silicon Labs has filed counterclaims for infringement on five (5) of the nineteen (19) patents and one (1) additional Silicon Labs patent. On September 13, 2012, Silicon Labs filed a motion for preliminary injunction requesting an injunction on our MxL601 product based upon alleged infringement of U.S. Patent No. 7,200,364. The hearing on the preliminary injunction motion is set for November 2, 2012. The Court has scheduled a claims construction hearing for April 19, 2013 and scheduled trial to commence on February 11, 2014.

On July 17, 2012, Silicon Labs filed a complaint for patent infringement against us in United States District Court for the Southern District of California. The Silicon Labs complaint asserts that a wide range of our products infringe a single Silicon Labs patent, U.S. Patent No. 7,035,607, or the ‘607 patent. The ‘607 patent is related to several of the nineteen (19) patents on which we filed a declaratory judgment action against Silicon Labs. The Silicon Labs complaint seeks damages and injunctive relief against our products. We have filed counterclaims for infringement on three (3) patents owned by us – United States Patent Nos. 7,362,178; 8,198,940; and 7,778,613. Silicon Labs has filed a motion to dismiss or transfer our counterclaims for infringement to the United States District Court for the Western District of Texas. The Court denied that motion. No trial date has been set.

On July 30, 2012, Silicon Labs filed a declaratory judgment complaint in United States District Court for the Western District of Texas against us seeking an order that Silicon Labs’ products do not infringe the three (3) patents owned by us asserted as counterclaims in the second Southern District of California action. The declaratory judgment complaint further seeks a ruling that the patents are invalid. We have filed a motion to dismiss for lack of personal jurisdiction, and the Court has granted limited jurisdictional discovery related to the issue. No trial date has been set.

We have not recorded any accrual for loss contingencies associated with Silicon Labs litigation; determined that an unfavorable outcome is probable or reasonably possible; or determined that the amount or range of any possible loss is reasonably estimable.

Other Matters

In addition, from time to time, we are subject to threats of litigation or actual litigation in the ordinary course of business, some of which may be material. Other than the Silicon Labs litigation described above, we believe that there are no other currently pending matters that, if determined adversely to us, would have a material effect on our business or that would not be covered by our existing liability insurance maintained by us.

Risks Related to Our Business

We face intense competition and expect competition to increase in the future, which could have an adverse effect on our revenue, revenue growth rate, if any, and market share.

The global semiconductor market in general, and the RF receiver market in particular, are highly competitive. We compete in different target markets to various degrees on the basis of a number of principal competitive factors, including our products’ performance, features and functionality, energy efficiency, size, ease of system design, customer support, product roadmap, reputation, reliability and price, as well as on the basis of our customer support, the quality of our product roadmap and our reputation. We expect competition to increase and intensify as more and larger semiconductor companies as well as the internal resources of large, integrated original equipment manufacturers, or OEMs, enter our markets. Increased competition could result in price pressure, reduced profitability and loss of market share, any of which could materially and adversely affect our business, revenue, revenue growth rates and operating results.

As our products are integrated into a variety of electronic devices, we compete with suppliers of both can tuners and traditional silicon RF receivers. Our competitors range from large, international companies offering a wide range of semiconductor products to smaller companies specializing in narrow markets and internal engineering groups within mobile device, television and set top box manufacturers, some of which may be our customers. Our primary competitors include Silicon Labs, NXP B.V., Maxim Integrated Products, Inc., RDA Microelectronics, Inc., Newport Media Inc., Broadcom Corporation, Entropic Communications, Inc. and Rafael Microelectronics, Inc. It is quite likely that competition in the markets in which we participate will increase in the future as existing competitors improve or expand their product offerings. In addition, it is quite likely that a number of other public and private companies are in the process of developing competing products for digital television and other broadband communication applications. Because our products often are building block semiconductors which provide functions that in some cases can be integrated into more complex integrated circuits, we also face competition from manufacturers of integrated circuits, some of which may be existing customers that develop their own integrated circuit products. If we cannot offer an attractive solution for applications where our competitors offer more fully integrated tuner/demodulator/video processing products, we may lose significant market share to our competitors. Certain of our competitors have fully integrated tuner/demodulator/video processing solutions targeting high performance cable or DTV applications, and thereby potentially provide customers with smaller and cheaper solutions.

Our ability to compete successfully depends on elements both within and outside of our control, including industry and general economic trends. During past periods of downturns in our industry, competition in the markets in which we operate intensified as manufacturers of semiconductors reduced prices in order to combat production overcapacity and high inventory levels. Many of our competitors have substantially greater financial and other resources with which to withstand similar adverse economic or market conditions in the future. Moreover, the competitive landscape is changing as a result of consolidation within our industry as some of our competitors have merged with or been acquired by other competitors, and other competitors have begun to collaborate with each other. These developments may materially and adversely affect our current and future target markets and our ability to compete successfully in those markets.

We depend on a limited number of customers for a substantial portion of our revenue, and the loss of, or a significant reduction in orders from, one or more of our major customers could have a material adverse effect on our revenue and operating results.

In the three months ended September 30, 2012, one customer accounted for approximately 21% of our net revenue, and our ten largest customers collectively accounted for approximately 60% of our net revenue. In the nine months ended September 30, 2012, one customer accounted for approximately 18% of our net revenue, and our ten largest customers collectively accounted for approximately 58% of our net revenue. In the three months ended September 30, 2011, two of our customers accounted for 12% and 11%, respectively, of our net revenue, and our ten largest customers collectively accounted for approximately 64% of our net revenue. In the nine months ended September 30, 2011, one customer accounted for approximately 16% of our net revenue, and our ten largest customers collectively accounted for approximately 57% of our net revenue. Our operating results for the foreseeable future will continue to depend on sales to a relatively small number of customers and on the ability of these customers to sell products that incorporate our RF receivers or RF receiver SoCs. In the future, these customers may decide not to purchase our products at all, may purchase fewer products than they did in the past, or may defer or cancel purchases or otherwise alter their purchasing patterns. Factors that could affect our revenue from these large customers include the following:

• substantially all of our sales to date have been made on a purchase order basis, which permits our customers to cancel, change or delay product purchase commitments with little or no notice to us and without penalty; and

• some of our customers have sought or are seeking relationships with current or potential competitors which may affect their purchasing decisions.

25

In addition, delays in development could impair our relationships with our strategic customers and negatively impact sales of the products under development. Moreover, it is possible that our customers may develop their own product or adopt a competitor’s solution for products that they currently buy from us. If that happens, our sales would decline and our business, financial condition and results of operations could be materially and adversely affected.

Our relationships with some customers may deter other potential customers who compete with these customers from buying our products. To attract new customers or retain existing customers, we may offer these customers favorable prices on our products. In that event, our average selling prices and gross margins would decline. The loss of a key customer, a reduction in sales to any key customer or our inability to attract new significant customers could seriously impact our revenue and materially and adversely affect our results of operations.

A significant portion of our revenue is attributable to demand for our products in markets for terrestrial set-top box and cable applications.

Prior to fiscal 2010, sales of our products to customers in the mobile electronic device market accounted for a significant portion of our revenue in prior periods; however, revenue derived from mobile electronic devices has declined since fiscal 2010 and is no longer an area of focus for the Company. For fiscal 2010, revenue directly attributable to terrestrial set-top box and cable applications accounted for approximately 39% of our net revenue. For fiscal 2011, revenue directly attributable to terrestrial set-top box and cable applications accounted for approximately 56% of our net revenue. For the three and nine months ended September 30, 2012, revenue directly attributable to terrestrial set-top box and cable applications accounted for approximately 85% and 83% of our net revenue, respectively. We currently expect this trend to continue in the remainder of fiscal 2012. Delays in the development of, or unexpected developments in, the terrestrial set-top box and cable application markets could have an adverse effect on order activity by manufacturers in these markets and, as a result, on our business, revenue, operating results and financial condition.

We may be unable to make the substantial and productive research and development investments which are required to remain competitive in our business.

The semiconductor industry requires substantial investment in research and development in order to develop and bring to market new and enhanced technologies and products. Many of our products originated with our research and development efforts and have provided us with a significant competitive advantage. Our research and development expense was $10.9 million and $33.8 in the three and nine months ended September 30, 2012, respectively, and $9.5 million and $30.0 million in the three and nine months ended September 30, 2011, respectively. In the nine months ended September 30, 2012, we continued to increase our research and development expenditures as part of our strategy of devoting focused research and development efforts on the development of innovative and sustainable product platforms. We are committed to investing in new product development internally in order to stay competitive in our markets and plan to maintain research and development and design capabilities for new solutions in advanced semiconductor process nodes such as 40nm and beyond. We do not know whether we will have sufficient resources to maintain the level of investment in research and development required to remain competitive as semiconductor process nodes continue to shrink and become increasingly complex. In addition, we cannot assure you that the technologies which are the focus of our research and development expenditures will become commercially successful.

Average selling prices of our products could decrease rapidly, which could have a material adverse effect on our revenue and gross margins.

We may experience substantial period-to-period fluctuations in future operating results due to the erosion of our average selling prices. From time to time, we have reduced the average unit price of our products due to competitive pricing pressures, new product introductions by us or our competitors, and for other reasons, and we expect that we will have to do so again in the future. If we are unable to offset any reductions in our average selling prices by increasing our sales volumes or introducing new products with higher margins, our revenue and gross margins will suffer. To support our gross margins, we must develop and introduce new products and product enhancements on a timely basis and continually reduce our and our customers’ costs. Failure to do so would cause our revenue and gross margins to decline.

If we fail to develop and introduce new or enhanced products on a timely basis, our ability to attract and retain customers could be impaired and our competitive position could be harmed.

We operate in a dynamic environment characterized by rapidly changing technologies and industry standards and technological obsolescence. To compete successfully, we must design, develop, market and sell new or enhanced products that provide increasingly higher levels of performance and reliability and meet the cost expectations of our customers. The introduction of new products by our competitors, the market acceptance of products based on new or alternative technologies, or the emergence of new industry standards could render our existing or future products obsolete. Our failure to anticipate or timely develop new or enhanced products or technologies in response to technological shifts could result in decreased revenue and our competitors winning more competitive bid processes, known as “design wins.” In particular, we may experience difficulties with product design, manufacturing, marketing or certification that could delay or prevent our development, introduction or marketing of new or enhanced products. If we fail to introduce new or enhanced products that meet the needs of our customers or penetrate new markets in a timely fashion, we will lose market share and our operating results will be adversely affected.

If we fail to penetrate new markets, our revenue, revenue growth rate, if any, and financial condition could be materially and adversely affected.

Currently, we sell most of our products to manufacturers of applications for television, cable modems and gateways and cable set-top boxes, automotive TV display, and to Chinese manufacturers of set top boxes for sale in various markets worldwide. Our future revenue growth, if any, will depend in part on our ability to expand beyond these markets with our RF receivers and RF receiver SoCs. Each of these markets presents distinct and substantial risks. If any of these markets does not develop as we currently anticipate, or if we are unable to penetrate them successfully, it could materially and adversely affect our revenue and revenue growth rate, if any.

We expect cable modems and set top boxes to represent our largest North American target market. The North American cable set top box market is dominated by only a few OEMs, including Motorola Solutions Inc, Cisco Systems, Inc., Arris Group, Inc. and Technicolor S.A. These OEMs are large, multinational corporations with substantial negotiating power relative to us. Securing design wins with any of these companies requires a substantial investment of our time and resources. Even if we succeed, additional testing and operational certifications will be required by the OEMs’ customers, which include large cable television companies such as Comcast Corporation and Time Warner Cable Inc. In addition, our products will need to be compatible with other components in our customers’ designs, including components produced by our competitors or potential competitors. There can be no assurance that these other companies will support or continue to support our products.

Finally, the markets for Internet Protocol television, or IPTV, and PCTV are nascent and relatively small. We have sold limited quantities of our products into these markets and cannot predict how, or to what extent, demand for our products in these markets will develop.

If we fail to penetrate these or other new markets upon which we target our resources, our revenue and revenue growth rate, if any, likely will decrease over time and our financial condition could suffer.

Our business, revenue and revenue growth, if any, will depend in part on the timing and development of the global transition from analog to digital television, which is subject to numerous regulatory and business risks outside our control.

For the three and nine months ended September 30, 2012, sales of our RF receiver products used in digital terrestrial television applications, or DTT, including digital televisions, automotive navigation displays, PCTV, IPTV, and terrestrial set top boxes, and modems and gateways for cable represented a significant portion of our revenues. We expect a significant portion of our revenue in future periods to continue to depend on the demand for DTT applications. In contrast to the United States, where the transition from analog to digital television occurred on a national basis in June 2009, in Europe and other parts of the world, the digital transition is being phased in on a local and regional basis and is expected to occur over many years. Most countries in Western Europe are expected to convert to digital television by the end of 2012, with the transition in Eastern Europe expected to continue through 2015. As a result, our future revenue will depend in part on government mandates requiring conversion from analog to digital television and on the timing and implementation of those mandates. If the transition to digital TV standards does not take place or is substantially delayed in Europe or other international markets, our business, revenue, operating results and financial condition would be materially and adversely affected. If during the transition to digital TV standards, consumers disproportionately purchase TV’s with digital or hybrid tuning capabilities, this could diminish the size of the market for our digital-to-analog converter set-top box solutions, and as result our business, revenue, operating results and financial condition would be materially and adversely affected.

We are subject to U.S. export control and economic sanctions laws relating to the sale of our products. Although we did not intend to do so, we may have violated certain of these laws in the past, and we cannot currently assess with certainty the nature and extent of fines or other penalties, if any, that U.S. governmental agencies may impose against us, our management, or other employees for these potential violations. Any fines, if materially different from our current estimates, and any other penalties that regulatory authorities may seek to impose could have a material adverse effect on our business, operating results, and financial condition.

As noted in our Current Report on Form 8-K filed on February 7, 2012, in the first quarter of 2012, we determined that we may have taken actions that could constitute facilitation (within the meaning of applicable sanctions and export control laws) of shipments of foreign produced products to Iran or taken other actions that may be in violation of U.S. export control and economic sanctions laws. Specifically, certain of our tuner products, which are foreign produced and not subject to U.S. export controls, were included in set-top converter boxes produced by set-top box manufacturers in Asia to permit conversion of digital television signals to analog signals in international markets, including Iran, using the DVB-T, or Digital Video Broadcasting – Terrestrial, broadcast standard. The DVB-T standard is used in most of Europe, Asia (excluding China), Australia, and Africa as well as in parts of the Middle East, including Iran. While the underlying shipment of our tuners into Iran by foreign manufacturers of these set-top boxes may have been lawful, we may have violated applicable sanctions and export control laws without the proper U.S. Government authorization.

27

We initially identified these potential violations internally, rather than as a result of a third-party audit or government investigation, and upon learning of these potential violations, our audit committee promptly retained outside counsel to conduct a review of our sanctions and export control compliance. On February 7, 2012, we made voluntary initial filings with the Office of Foreign Assets Control of the United States Department of the Treasury, or OFAC, and with the Bureau of Industry and Security of the United States Department of Commerce, or BIS, notifying these regulatory agencies that we were conducting a review of export control matters and that we would submit any supplemental voluntary self-disclosures once our internal review was complete. The initial stage of the review was concluded in March 2012. Subsequently, we also learned that we were not in full compliance with BIS’s deemed export rule which requires, in some circumstances, that the companies obtain a deemed export license from BIS for employment of certain foreign nationals even if, as was our situation, we had obtained an H1-B visa prior to employing the individual. We have now applied for such license with respect to the subject employee.

In connection with its March 2012 review, our audit committee determined that our management team lacked sufficient familiarity with and understanding of export control and sanctions laws and their applicability to our products and services. Our audit committee concluded that our management team did not intentionally or knowingly violate applicable sanctions and export control laws.

We submitted final voluntary disclosures to OFAC on June 1, 2012 and BIS on June 15, 2012 and July 11, 2012. OFAC and BIS may conclude that our actions resulted in violations that warrant the imposition of penalties that could include fines, termination of our ability to export our products, and/or referral for criminal prosecution. On September 27, 2012, OFAC closed out the Company’s Voluntary Self Disclosure with the issuance of a cautionary letter, which means that no monetary or other penalty was imposed against the Company. The BIS Voluntary Self Disclosure remains pending and the Company informed BIS that OFAC closed out its case with a cautionary letter.

Penalties and potential criminal enforcement actions could be imposed against us and/or our management and certain of our employees. We cannot predict when BIS will complete its review of our submissions, and resolution of the BIS matter could take substantial time and require substantial expenditure and management resources, either of which could be harmful to our business and operating results.

Any fines that BIS may impose on us could be material to our operating results in the period in which they are imposed and could have a material adverse effect on our financial condition. The maximum civil monetary penalty for each violation is up to $250 or twice the value of the transaction, whichever is greater. In the three and nine months ended September 30, 2012, the Company reduced its previously recorded OFAC penalties and fines by $625. Based upon facts known to us to date, we have recorded total charges of $250 for this export compliance matter, representing management’s estimated exposure for BIS fines in accordance with applicable accounting literature. Should additional facts be discovered in the future and/or should actual fines or other penalties differ from our estimates, our business, operating results, and financial condition could be materially and negatively affected. In that regard, we cannot guarantee that BIS will agree with our assessments of the quantity and nature of the potential violations. As a result, BIS could seek to impose higher fines and penalties than those we have estimated to date, and we could incur significant additional legal expenses in response. As a result of increased awareness relative to U.S. export control and economic sanction laws relating to the sale of our products, we have implemented additional export control compliance management oversight and have undertaken remedial measures to reduce the risk of similar events occurring in the future.

We are currently parties to intellectual property litigation and may face additional claims of intellectual property infringement. Current litigation and any future litigation could be time-consuming, costly to defend or settle and result in the loss of significant rights.

The semiconductor industry is characterized by companies that hold large numbers of patents and other intellectual property rights and that vigorously pursue, protect and enforce intellectual property rights. From time to time, third parties may assert against us and our customers and distributors their patent and other intellectual property rights to technologies that are important to our business.

Silicon Labs Litigation

On May 13, 2012, the Company filed a declaratory judgment complaint in United States District Court for the Southern District of California against Silicon Labs, as defendant, seeking an order that the Company’s CMOS hybrid tuner products, such as the MxL301 and MxL601, do not infringe nineteen (19) patents owned by Silicon Labs. The declaratory judgment complaint further seeks a ruling that the defendant’s patents are invalid. Silicon Labs has filed counterclaims for infringement on five (5) of the nineteen (19) patents and one (1) additional Silicon Labs patent. On September 13, 2012, Silicon Labs filed a motion for preliminary injunction requesting an injunction on the Company’s MxL601 product based upon alleged infringement of U.S. Patent No. 7,200,364. The hearing on the preliminary injunction motion is set for November 2, 2012. The Court has scheduled a claims construction hearing for April 19, 2013 and scheduled trial to commence on February 11, 2014.

28

On July 17, 2012, Silicon Labs filed a complaint for patent infringement against the Company in United States District Court for the Southern District of California. The Silicon Labs complaint asserts that a wide range of the Company’s products infringe a single Silicon Labs patent, U.S. Patent No. 7,035,607, or the ‘607 patent. The ‘607 patent is related to several of the nineteen (19) patents on which the Company filed a declaratory judgment action against Silicon Labs. The Silicon Labs complaint seeks damages and injunctive relief against the Company’s products. The Company has filed counterclaims for infringement on three (3) patents owned by the Company – United States Patent Nos. 7,362,178; 8,198,940; and 7,778,613. Silicon Labs has filed a motion to dismiss or transfer the Company’s counterclaims for infringement to the United States District Court for the Western District of Texas. The Court denied that motion. No trial date has been set.

On July 30, 2012, Silicon Labs filed a declaratory judgment complaint in United States District Court for the Western District of Texas against the Company seeking an order that Silicon Labs’ products do not infringe the three (3) patents owned by the Company asserted as counterclaims in the second Southern District of California action. The declaratory judgment complaint further seeks a ruling that the patents are invalid. The Company has filed a motion to dismiss for lack of personal jurisdiction, and the Court has granted limited jurisdictional discovery related to the issue. No trial date has been set.

We have not recorded any accrual for loss contingencies associated with Silicon Labs litigation; determined that an unfavorable outcome is probable or reasonably possible; or determined that the amount or range of any possible loss is reasonably estimable.

Claims that our products, processes or technology infringe third-party intellectual property rights, regardless of their merit or resolution and including the Silicon Labs claims, could be costly to defend or settle and could divert the efforts and attention of our management and technical personnel. In addition, many of our customer and distributor agreements require us to indemnify and defend our customers or distributors from third-party infringement claims and pay damages in the case of adverse rulings. Claims of this sort also could harm our relationships with our customers or distributors and might deter future customers from doing business with us. We believe that Silicon Labs has sought to impair our relationships with prospective customers, and we filed our declaratory action complaint in partial response to accusations made by Silicon Labs to our customers. We do not know whether we will prevail in these proceedings given the complex technical issues and inherent uncertainties in intellectual property litigation. If any pending or future proceedings result in an adverse outcome, we could be required to:

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

• pay substantial damages for infringement;

• expend significant resources to develop non-infringing products, processes or technology;

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

• cross-license our technology to a competitor to resolve an infringement claim, which could weaken our ability to compete with that competitor; or

• pay substantial damages to our customers or end users to discontinue their use of or to replace infringing technology sold to them with non-infringing technology.

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

We utilize a significant amount of intellectual property in our business. If we are unable to protect our intellectual property, our business could be adversely affected.

Our success depends in part upon our ability to protect our intellectual property. To accomplish this, we rely on a combination of intellectual property rights, including patents, copyrights, trademarks and trade secrets in the United States and in selected foreign countries where we believe filing for such protection is appropriate. Effective patent, copyright, trademark and trade secret protection may be unavailable, limited or not applied for in some countries. Some of our products and technologies are not covered by any patent or patent application. We cannot guarantee that:

• any of our present or future patents or patent claims will not lapse or be invalidated, circumvented, challenged or abandoned;

• our intellectual property rights will provide competitive advantages to us;

29

• our ability to assert our intellectual property rights against potential competitors or to settle current or future disputes will not be limited by our agreements with third parties;

• any of our pending or future patent applications will be issued or have the coverage originally sought;

• our intellectual property rights will be enforced in jurisdictions where competition may be intense or where legal protection may be weak;

• any of the trademarks, copyrights, trade secrets or other intellectual property rights that we presently employ in our business will not lapse or be invalidated, circumvented, challenged or abandoned; or

• we will not lose the ability to assert our intellectual property rights against or to license our technology to others and collect royalties or other payments.

In addition, our competitors or others may design around our protected patents or technologies. Effective intellectual property protection may be unavailable or more limited in one or more relevant jurisdictions relative to those protections available in the United States, or may not be applied for in one or more relevant jurisdictions. If we pursue litigation to assert our intellectual property rights, as we have against Silicon Labs, an adverse decision in any of these legal actions could limit our ability to assert our intellectual property rights, limit the value of our technology or otherwise negatively impact our business, financial condition and results of operations.

Monitoring unauthorized use of our intellectual property is difficult and costly. Unauthorized use of our intellectual property may have occurred or may occur in the future. Although we have taken steps to minimize the risk of this occurring, any such failure to identify unauthorized use and otherwise adequately protect our intellectual property would adversely affect our business. Moreover, if we are required to commence litigation, whether as a plaintiff or defendant and has occurred with Silicon Labs, not only will this be time-consuming, but we will also be forced to incur significant costs and divert our attention and efforts of our employees, which could, in turn, result in lower revenue and higher expenses.

We also rely on customary contractual protections with our customers, suppliers, distributors, employees and consultants, and we implement security measures to protect our trade secrets. We cannot assure you that these contractual protections and security measures will not be breached, that we will have adequate remedies for any such breach or that our suppliers, employees or consultants will not assert rights to intellectual property arising out of such contracts.

In addition, we have a number of third-party patent and intellectual property license agreements. Some of these license agreements require us to make one-time payments or ongoing royalty payments. Also, a few of our license agreements contain most-favored nation clauses or other price restriction clauses which may affect the amount we may charge for our products, processes or technology. We cannot guarantee that the third-party patents and technology we license will not be licensed to our competitors or others in the semiconductor industry. In the future, we may need to obtain additional licenses, renew existing license agreements or otherwise replace existing technology. We are unable to predict whether these license agreements can be obtained or renewed or the technology can be replaced on acceptable terms, or at all.

In connection with settling a trademark dispute with Linear Technology Corporation, we agreed not to register the “MAXLINEAR” mark or any other marks containing the term “LINEAR”. We may continue to use “MAXLINEAR” as a corporate identifier, including to advertise our products and services, but may not use that mark on our products. The agreement does not affect our ability to use our registered trademark “MxL”, which we use on our products. Due to our agreement not to register the “MAXLINEAR” mark, our ability to effectively prevent third parties from using the “MAXLINEAR” mark in connection with similar products or technology may be affected. If we are unable to protect our trademarks, we may experience difficulties in achieving and maintaining brand recognition and customer loyalty.

Continued adverse U.S. and international economic conditions, including factors that adversely affect consumer spending for the products that incorporate our integrated circuits, could adversely affect our revenues, margins, and operating results.

Since September 2008, the global credit markets and the financial services industry have been experiencing a period of unprecedented turmoil and upheaval characterized by the bankruptcy, failure, collapse or sale of various financial institutions and an unprecedented level of intervention from U.S. and foreign governments. Recently, the credit crisis has reemerged in Europe with threats of credit default by certain member countries of the European Union, and by substantial budgetary and fiscal constraints, including substantial budget reductions in larger European Union countries such as Germany and the United Kingdom. Our products are incorporated in numerous consumer devices, and demand for our products will ultimately be driven by consumer demand for products such as televisions, automobiles, cable modems, and set top boxes. Many of these purchases are discretionary. In addition, our recent revenue growth has been attributable in large part to purchases of digital-to-analog set top converter boxes in various geographies including Europe. Partially in response to economic and political developments, Greece recently extended the date for its deadline for switching to exclusive digital television broadcasts. Similar extensions in other European countries could adversely affect our revenue and growth. These events, together with the current adverse economic conditions facing the broader economy and, in particular, the semiconductor and communications industries, have adversely affected, and may continue to adversely affect, our business, particularly to the extent that consumers decrease their discretionary spending for devices deploying our products.

30

We rely on a limited number of third parties to manufacture, assemble and test our products, and the failure to manage our relationships with our third-party contractors successfully could adversely affect our ability to market and sell our products.

We do not have our own manufacturing facilities. We operate an outsourced manufacturing business model that utilizes third-party foundry and assembly and test capabilities. As a result, we rely on third-party foundry wafer fabrication and assembly and test capacity, including sole sourcing for many components or products. Currently, all of our products are manufactured by United Microelectronics Corporation, or UMC, Silterra Malaysia Sdn Bhd, Global Foundries, and Semiconductor Manufacturing International Corporation, or SMIC, at foundries in Taiwan, Singapore, Malaysia, and China. We also use third-party contractors for all of our assembly and test operations.

Relying on third party manufacturing, assembly and testing presents significant risks to us, including the following:

• failure by us, our customers, or their end customers to qualify a selected supplier;

• capacity shortages during periods of high demand;

• reduced control over delivery schedules and quality;

• shortages of materials;

• misappropriation of our intellectual property;

• limited warranties on wafers or products supplied to us; and

• potential increases in prices.

The ability and willingness of our third-party contractors to perform is largely outside our control. If one or more of our contract manufacturers or other outsourcers fails to perform its obligations in a timely manner or at satisfactory quality levels, our ability to bring products to market and our reputation could suffer. For example, in the event that manufacturing capacity is reduced or eliminated at one or more facilities, including as a response to the recent worldwide decline in the semiconductor industry, manufacturing could be disrupted, we could have difficulties fulfilling our customer orders and our net revenue could decline. In addition, if these third parties fail to deliver quality products and components on time and at reasonable prices, we could have difficulties fulfilling our customer orders, our net revenue could decline and our business, financial condition and results of operations would be adversely affected.

Additionally, our manufacturing capacity may be similarly reduced or eliminated at one or more facilities due to the fact that our fabrication and assembly and test contractors are all located in the Pacific Rim region, principally in Taiwan, Singapore and Malaysia. The risk of earthquakes in these geographies is significant due to the proximity of major earthquake fault lines, and Taiwan in particular is also subject to typhoons and other Pacific storms. Earthquakes, fire, flooding, or other natural disasters in Taiwan or the Pacific Rim region, or political unrest, war, labor strikes, work stoppages or public health crises, such as outbreaks of H1N1 flu, in countries where our contractors’ facilities are located could result in the disruption of our foundry, assembly or test capacity. Any disruption resulting from these events could cause significant delays in shipments of our products until we are able to shift our manufacturing, assembly or test from the affected contractor to another third-party vendor. There can be no assurance that alternative capacity could be obtained on favorable terms, if at all.

We do not have any long-term supply contracts with our contract manufacturers or suppliers, and any disruption in our supply of products or materials could have a material adverse effect on our business, revenue and operating results.

We currently do not have long-term supply contracts with any of our third-party vendors, including UMC, Silterra Malaysia Sdn Bhd, Global Foundries, and SMIC. We make substantially all of our purchases on a purchase order basis, and neither UMC nor our other contract manufacturers are required to supply us products for any specific period or in any specific quantity. Foundry capacity may not be available when we need it or at reasonable prices. Availability of foundry capacity has in the past been reduced from time to time due to strong demand. Foundries can allocate capacity to the production of other companies’ products and reduce deliveries to us on short notice. It is possible that foundry customers that are larger and better financed than we are, or that have long-term agreements with our foundry, may induce our foundry to reallocate capacity to them. This reallocation could impair our ability to secure the supply of components that we need. We expect that it would take approximately nine to twelve months to transition performance of our foundry or assembly services to new providers. Such a transition would likely require a qualification process by our customers or their end customers. We generally place orders for products with some of our suppliers approximately four to five months prior to the anticipated delivery date, with order volumes based on our forecasts of demand from our customers. Accordingly, if we inaccurately forecast demand for our products, we may be unable to obtain adequate and cost-effective foundry or assembly capacity from our third-party contractors to meet our customers’ delivery requirements, or we may accumulate excess inventories. On occasion, we have been unable to adequately respond to unexpected increases in customer purchase orders and therefore were unable to benefit from this incremental demand. None of our third-party contractors has provided any assurance to us that adequate capacity will be available to us within the time required to meet additional demand for our products.

31

To address capacity considerations, we are in the process of qualifying additional semiconductor fabricators. Qualification will not occur if we identify a defect in a fabricator’s manufacturing process or if our customers choose not to invest the time and expense required to qualify the proposed fabricator. If full qualification of a fabricator does not occur, we may not be able to sell all of the materials produced by this fabricator or to fulfill demand for our products, which would adversely affect our business, revenue and operating results. In addition, the resulting write-off of unusable inventories would have an adverse effect on our operating results.

Due to our limited operating history, we may have difficulty accurately predicting our future revenue and appropriately budgeting our expenses.

We have only a limited operating history from which to predict future revenue. This limited operating experience, combined with the rapidly evolving nature of the markets in which we sell our products, substantial uncertainty concerning how these markets may develop and other factors beyond our control, reduces our ability to accurately forecast quarterly or annual revenue. We are currently expanding our staffing and increasing our expense levels in anticipation of future revenue growth. If our revenue does not increase as anticipated, we could incur significant losses due to our higher expense levels if we are not able to decrease our expenses in a timely manner to offset any shortfall in future revenue.

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

We have experienced significant growth in a short period of time. Our net revenue increased from approximately $51.4 million in 2009 to approximately $68.7 million in 2010 and approximately $71.9 million in 2011. We may not achieve similar growth rates in future periods. You should not rely on our operating results for any prior quarterly or annual periods as an indication of our future operating performance. If we are unable to maintain adequate revenue growth, our financial results could suffer and our stock price could decline.

To manage our growth successfully and handle the responsibilities of being a public company, we believe we must effectively, among other things:

• recruit, hire, train and manage additional qualified engineers for our research and development activities, especially in the positions of design engineering, product and test engineering and applications engineering;

• add sales personnel and expand customer engineering support offices;

• implement and improve our administrative, financial and operational systems, procedures and controls; and

• enhance our information technology support for enterprise resource planning and design engineering by adapting and expanding our systems and tool capabilities, and properly training new hires as to their use.

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

If we are unable to attract, train and retain qualified personnel, especially our design and technical personnel, we may not be able to execute our business strategy effectively.

Our future success depends on our ability to retain, attract and motivate qualified personnel, including our management, sales and marketing and finance, and especially our design and technical personnel. We do not know whether we will be able to retain all of these personnel as we continue to pursue our business strategy. Historically, we have encountered difficulties in hiring and retaining qualified engineers because there is a limited pool of engineers with the expertise required in our field. Competition for these personnel is intense in the semiconductor industry. As the source of our technological and product innovations, our design and technical personnel represent a significant asset. The loss of the services of one or more of our key employees, especially our key design and technical personnel, or our inability to retain, attract and motivate qualified design and technical personnel, could have a material adverse effect on our business, financial condition and results of operations.

32

Our customers require our products and our third-party contractors to undergo a lengthy and expensive qualification process which does not assure product sales.

Prior to purchasing our products, our customers require that both our products and our third-party contractors undergo extensive qualification processes, which involve testing of the products in the customer’s system and rigorous reliability testing. This qualification process may continue for six months or more. However, qualification of a product by a customer does not assure any sales of the product to that customer. Even after successful qualification and sales of a product to a customer, a subsequent revision to the RF receiver or RF receiver SoC, changes in our customer’s manufacturing process or our selection of a new supplier may require a new qualification process, which may result in delays and in us holding excess or obsolete inventory. After our products are qualified, it can take six months or more before the customer commences volume production of components or devices that incorporate our products. Despite these uncertainties, we devote substantial resources, including design, engineering, sales, marketing and management efforts, to qualifying our products with customers in anticipation of sales. If we are unsuccessful or delayed in qualifying any of our products with a customer, sales of this product to the customer may be precluded or delayed, which may impede our growth and cause our business to suffer.

We are subject to risks associated with our distributors’ product inventories and product sell-through. Should any of our distributors cease or be forced to stop distributing our products, our business would suffer.

We currently sell a significant but declining portion of our products to customers through our distributors, who maintain their own inventories of our products. Sales to distributors accounted for 38% and 40% of our net revenue in the three and nine months ended September 30, 2012. If our distributors are unable to sell an adequate amount of their inventories of our products in a given quarter to manufacturers and end users or if they decide to decrease their inventories of our products for any reason, our sales to these distributors and our revenue may decline. In addition, if some distributors decide to purchase more of our products than are required to satisfy end customer demand in any particular quarter, inventories at these distributors would grow in that quarter. These distributors likely would reduce future orders until inventory levels realign with end customer demand, which could adversely affect our product revenue in a subsequent quarter.

Our reserve estimates with respect to the products stocked by our distributors are based principally on reports provided to us by our distributors, typically on a weekly basis. To the extent that this resale and channel inventory data is inaccurate or not received in a timely manner, we may not be able to make reserve estimates for future periods accurately or at all.

We are subject to order and shipment uncertainties, and differences between our estimates of customer demand and product mix and our actual results could negatively affect our inventory levels, sales and operating results.

Our revenue is generated on the basis of purchase orders with our customers rather than long-term purchase commitments. In addition, our customers can cancel purchase orders or defer the shipments of our products under certain circumstances. Our products are manufactured using a silicon foundry according to our estimates of customer demand, which requires us to make separate demand forecast assumptions for every customer, each of which may introduce significant variability into our aggregate estimate. We have limited visibility into future customer demand and the product mix that our customers will require, which could adversely affect our revenue forecasts and operating margins. Moreover, because our target markets are relatively new, many of our customers have difficulty accurately forecasting their product requirements and estimating the timing of their new product introductions, which ultimately affects their demand for our products. Historically, because of this limited visibility, actual results have been different from our forecasts of customer demand. Some of these differences have been material, leading to excess inventory or product shortages and revenue and margin forecasts above those we were actually able to achieve. These differences may occur in the future, and the adverse impact of these differences between forecasts and actual results could grow if we are successful in selling more products to some customers. In addition, the rapid pace of innovation in our industry could render significant portions of our inventory obsolete. Excess or obsolete inventory levels could result in unexpected expenses or increases in our reserves that could adversely affect our business, operating results and financial condition. Conversely, if we were to underestimate customer demand or if sufficient manufacturing capacity were unavailable, we could forego revenue opportunities, potentially lose market share and damage our customer relationships. In addition, any significant future cancellations or deferrals of product orders or the return of previously sold products due to manufacturing defects could materially and adversely impact our profit margins, increase our write-offs due to product obsolescence and restrict our ability to fund our operations.

Winning business is subject to lengthy competitive selection processes that require us to incur significant expenditures. Even if we begin a product design, a customer may decide to cancel or change its product plans, which could cause us to generate no revenue from a product and adversely affect our results of operations.

We are focused on securing design wins to develop RF receivers and RF receiver SoCs for use in our customers’ products. These selection processes typically are lengthy and can require us to incur significant design and development expenditures and dedicate scarce engineering resources in pursuit of a single customer opportunity. We may not win the competitive selection process and may never generate any revenue despite incurring significant design and development expenditures. These risks are exacerbated by the fact that some of our customers’ products likely will have short life cycles. Failure to obtain a design win could prevent us from offering an entire generation of a product, even though this has not occurred to date. This could cause us to lose revenue and require us to write off obsolete inventory, and could weaken our position in future competitive selection processes.

33

After securing a design win, we may experience delays in generating revenue from our products as a result of the lengthy development cycle typically required. Our customers generally take a considerable amount of time to evaluate our products. The typical time from early engagement by our sales force to actual product introduction runs from nine to twelve months for the consumer market, to as much as 12 to 36 months for the automotive TV display market. The delays inherent in these lengthy sales cycles increase the risk that a customer will decide to cancel, curtail, reduce or delay its product plans, causing us to lose anticipated sales. In addition, any delay or cancellation of a customer’s plans could materially and adversely affect our financial results, as we may have incurred significant expense and generated no revenue. Finally, our customers’ failure to successfully market and sell their products could reduce demand for our products and materially and adversely affect our business, financial condition and results of operations. If we were unable to generate revenue after incurring substantial expenses to develop any of our products, our business would suffer.

Our operating results are subject to substantial quarterly and annual fluctuations and may fluctuate significantly due to a number of factors that could adversely affect our business and our stock price.

Our revenue and operating results have fluctuated in the past and are likely to fluctuate in the future. These fluctuations may occur on a quarterly and on an annual basis and 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;

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

• fluctuations in the levels of component inventories held by our customers;

• the gain or loss of significant customers;

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

• our ability to develop, introduce and market new products and technologies on a timely basis;

• the timing and extent of product development costs;

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

• incurrence of research and development and related new product expenditures;

• seasonality or cyclical fluctuations in our markets;

• currency fluctuations;

• fluctuations in IC manufacturing yields;

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

• changes in our product mix or customer mix;

• intellectual property disputes;

• loss of key personnel or the shortage of available skilled workers; and

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

The foregoing factors are difficult to forecast, and these, as well as other factors, could materially adversely affect our quarterly or annual operating results. We typically are required to incur substantial development costs in advance of a prospective sale with no certainty that we will ever recover these costs. A substantial amount of time may pass between a design win and the generation of revenue related to the expenses previously incurred, which can potentially cause our operating results to fluctuate significantly from period to period. In addition, a significant amount of our operating expenses are relatively fixed in nature due to our significant sales, research and development costs. Any failure to adjust spending quickly enough to compensate for a revenue shortfall could magnify its adverse impact on our results of operations.

Our business would be adversely affected by the departure of existing members of our senior management team.

Our success depends, in large part, on the continued contributions of our senior management team, in particular, the services of Kishore Seendripu, Ph.D., our Chairman, President and Chief Executive Officer, Curtis Ling, Ph.D., our Chief Technical Officer and a Director, and Madhukar Reddy, Ph.D., our Vice President, IC and RF Systems Engineering. None of our senior management team is bound by written employment contracts to remain with us for a specified period. In addition, we have not entered into non-compete agreements with members of our senior management team. The loss of any member of our senior management team could harm our ability to implement our business strategy and respond to the rapidly changing market conditions in which we operate.

The complexity of our products could result in unforeseen delays or expenses caused by undetected defects or bugs, which could reduce the market acceptance of our new products, damage our reputation with current or prospective customers and adversely affect our operating costs.

Highly complex products like our RF receivers and RF receiver SoCs may contain defects and bugs when they are first introduced or as new versions are released. Due to our limited operating history, defects and bugs that may be contained in our products may not yet have manifested. We have in the past experienced, and may in the future experience, defects and bugs. If any of our products contains defects or bugs, or has reliability, quality or compatibility problems, we may not be able to successfully correct these problems. Consequently, our reputation may be damaged and customers may be reluctant to buy our products, which could materially and adversely affect our ability to retain existing customers and attract new customers, and our financial results. In addition, these defects or bugs could interrupt or delay sales to our customers. If any of these problems are not found until after we have commenced commercial production of a new product, we may be required to incur additional development costs and product recall, repair or replacement costs, and our operating costs could be adversely affected. These problems may also result in warranty or product liability claims against us by our customers or others that may require us to make significant expenditures to defend these claims or pay damage awards. In the event of a warranty claim, we may also incur costs if we compensate the affected customer. We maintain product liability insurance, but this insurance is limited in amount and subject to significant deductibles. There is no guarantee that our insurance will be available or adequate to protect against all claims. We also may incur costs and expenses relating to a recall of one of our customers’ products containing one of our devices. The process of identifying a recalled product in devices that have been widely distributed may be lengthy and require significant resources, and we may incur significant replacement costs, contract damage claims from our customers and reputational harm. Costs or payments made in connection with warranty and product liability claims and product recalls could materially affect our financial condition and results of operations.

The use of open source software in our products, processes and technology may expose us to additional risks and harm our intellectual property.

Our products, processes and technology sometimes utilize and incorporate software that is subject to an open source license. Open source software is typically freely accessible, usable and modifiable. Certain open source software licenses require a user who intends to distribute the open source software as a component of the user’s software to disclose publicly part or all of the source code to the user’s software. In addition, certain open source software licenses require the user of such software to make any derivative works of the open source code available to others on unfavorable terms or at no cost. This can subject previously proprietary software to open source license terms.

While we monitor the use of all open source software in our products, processes and technology and try to ensure that no open source software is used in such a way as to require us to disclose the source code to the related product, processes or technology when we do not wish to do so, such use could inadvertently occur. Additionally, if a third party software provider has incorporated certain types of open source software into software we license from such third party for our products, processes or technology, we could, under certain circumstances, be required to disclose the source code to our products, processes or technology. This could harm our intellectual property position and have a material adverse effect on our business, results of operations and financial condition.

We rely on third parties to provide services and technology necessary for the operation of our business. Any failure of one or more of our partners, vendors, suppliers or licensors to provide these services or technology could have a material adverse effect on our business.

We rely on third-party vendors to provide critical services, including, among other things, services related to accounting, billing, human resources, information technology, network development, network monitoring, in-licensing and intellectual property that we cannot or do not create or provide ourselves. We depend on these vendors to ensure that our corporate infrastructure will consistently meet our business requirements. The ability of these third-party vendors to successfully provide reliable and high quality services is subject to technical and operational uncertainties that are beyond our control. While we may be entitled to damages if our vendors fail to perform under their agreements with us, our agreements with these vendors limit the amount of damages we may receive. In addition, we do not know whether we will be able to collect on any award of damages or that these damages would be sufficient to cover the actual costs we would incur as a result of any vendor’s failure to perform under its agreement with us. Any failure of our corporate infrastructure could have a material adverse effect on our business, financial condition and results of operations. Upon expiration or termination of any of our agreements with third-party vendors, we may not be able to replace the services provided to us in a timely manner or on terms and conditions, including service levels and cost, that are favorable to us and a transition from one vendor to another vendor could subject us to operational delays and inefficiencies until the transition is complete.

35

Additionally, we incorporate third-party technology into and with some of our products, and we may do so in future products. The operation of our products could be impaired if errors occur in the third-party technology we use. It may be more difficult for us to correct any errors in a timely manner if at all because the development and maintenance of the technology is not within our control. There can be no assurance that these third parties will continue to make their technology, or improvements to the technology, available to us, or that they will continue to support and maintain their technology. Further, due to the limited number of vendors of some types of technology, it may be difficult to obtain new licenses or replace existing technology. Any impairment of the technology or our relationship with these third parties could have a material adverse effect on our business.

Unanticipated changes in our tax rates could affect our future results.

Since we operate in different countries and are subject to taxation in different jurisdictions, our future effective tax rates could be impacted by changes in such countries’ tax laws or their interpretations. Both domestic and international tax laws are subject to change as a result of changes in fiscal policy, changes in legislation, evolution of regulation and court rulings. The application of these tax laws and related regulations is subject to legal and factual interpretation, judgment and uncertainty. Recently, U.S. President Barack Obama’s administration proposed significant changes to the U.S. international tax laws that could limit U.S. deductions for expenses related to un-repatriated foreign-source income, and modify the U.S. foreign tax credit and “check-the-box” rules. We cannot determine whether these proposals will be enacted into law or what, if any, changes may be made to such proposals prior to their being enacted into law. If the U.S. tax laws change in a manner that increases our tax obligation, it could result in a material adverse impact on our net income and our financial position.

Our future effective tax rate could be unfavorably affected by unanticipated changes in the valuation of our deferred tax assets and liabilities. Changes in our effective tax rate could have a material adverse impact on our results of operations. We record a valuation allowance to reduce our net deferred tax assets to the amount that we believe is more likely than not to be realized. In assessing the need for a valuation allowance, we consider historical levels of income, expectations and risks associated with estimates of future taxable income and ongoing prudent and practical tax planning strategies. On a periodic basis we evaluate our deferred tax asset balance for realizability. To the extent we believe it is more likely than not that some portion of our deferred tax assets will not be realized, we will recognize a valuation allowance against the deferred tax asset. Realization of our deferred tax assets is dependent primarily upon future U.S. taxable income. During the year ended December 31, 2011, we established a full valuation allowance on our net federal deferred tax assets.

Our business, financial condition and results of operations could be adversely affected by the political and economic conditions of the countries in which we conduct business and other factors related to our international operations.

We sell our products throughout the world. Sales to end customers in Asia accounted for 94% and 90% of our net revenue in the three and nine months ended September 30, 2012. In addition, approximately 25% of our employees are located outside of the United States. All of our products are manufactured, assembled and tested in Asia, and all of our major distributors are located in Asia. Multiple factors relating to our international operations and to particular countries in which we operate could have a material adverse effect on our business, financial condition and results of operations. These factors include:

• changes in political, regulatory, legal or economic conditions;

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

• disruptions of capital and trading markets;

• changes in import or export licensing requirements;

• transportation delays;

• civil disturbances or political instability;

• geopolitical turmoil, including terrorism, war or political or military coups;

• public health emergencies;

• differing employment practices and labor standards;

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

• local business and cultural factors that differ from our customary standards and practices;

• nationalization and expropriation;

36

• changes in tax laws;

• currency fluctuations relating to our international operating activities; and

• difficulty in obtaining distribution and support.

In addition to a significant portion of our wafer supply coming from Taiwan, substantially all of our products undergo packaging and final test in Taiwan. Any conflict or uncertainty in this country, including due to natural disaster or public health or safety concerns, could have a material adverse effect on our business, financial condition and results of operations. In addition, if the government of any country in which our products are manufactured or sold sets technical standards for products manufactured in or imported into their country that are not widely shared, it may lead some of our customers to suspend imports of their products into that country, require manufacturers in that country to manufacture products with different technical standards and disrupt cross-border manufacturing relationships which, in each case, could have a material adverse effect on our business, financial condition and results of operations.

We also are subject to risks associated with international political conflicts involving the U.S. government. For example, in 2008 we were instructed by the U.S. Department of Homeland Security to cease using Polar Star International Company Limited, a distributor based in Hong Kong, that delivered third-party products, to a political group that the U.S. government did not believe should have been provided with the products in question. As a result, we immediately ceased all business operations with that distributor. The loss of Polar Star as a distributor did not materially delay shipment of our products because Polar Star was a non-exclusive distributor and we had in place alternative distribution arrangements. However, we cannot provide assurances that similar disruptions of distribution arrangements in the future will not result in delayed shipments until we are able to identify alternative distribution channels, which could include a requirement to increase our direct sales efforts. Loss of a key distributor under similar circumstances could have an adverse effect on our business, revenues and operating results.

If we suffer losses to our facilities or distribution system due to catastrophe, our operations could be seriously harmed.

Our facilities and distribution system, and those of our third-party contractors, are subject to risk of catastrophic loss due to fire, flood or other natural or man-made disasters. A number of our facilities and those of our contract manufacturers are located in areas with above average seismic activity. The foundries that manufacture all of our wafers are located in Taiwan, Singapore and Malaysia, and all of the third-party contractors who assemble and test our products also are located in Asia. In addition, our headquarters are located in Southern California. The risk of an earthquake in the Pacific Rim region or Southern California is significant due to the proximity of major earthquake fault lines. For example, in 2002 and 2003, major earthquakes occurred in Taiwan. Any catastrophic loss to any of these facilities would likely disrupt our operations, delay production, shipments and revenue and result in significant expenses to repair or replace the facility. In particular, any catastrophic loss at the Carlsbad and Irvine, California, Taiwan, Singapore or Shanghai facilities would materially and adversely affect our business.

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.

We must conform the manufacture and distribution of our semiconductors 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.

37

Investor confidence may be adversely impacted if we are unable to comply with Section 404 of the Sarbanes-Oxley Act of 2002, and as a result, our stock price could decline.

We are subject to rules adopted by the Securities Exchange Commission, or SEC, pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, or Sarbanes-Oxley Act, which require us to include in our Annual Report on Form 10-K our management’s report on, and assessment of the effectiveness of, our internal controls over financial reporting.

If we fail to maintain the adequacy of our internal controls, there is a risk that we will not comply with all of the requirements imposed by Section 404. Moreover, effective internal controls, particularly those related to revenue recognition, are necessary for us to produce reliable financial reports and are important to helping prevent financial fraud. Any of these possible outcomes could result in an adverse reaction in the financial marketplace due to a loss of investor confidence in the reliability of our consolidated financial statements and could result in investigations or sanctions by the SEC, the New York Stock Exchange, or NYSE, or other regulatory authorities or in stockholder litigation. Any of these factors ultimately could harm our business and could negatively impact the market price of our securities. Ineffective control over financial reporting could also cause investors to lose confidence in our reported financial information, which could adversely affect the trading price of our common stock.

Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives. However, our management, including our principal executive officer and principal financial officer, does not expect that our disclosure controls and procedures will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected.

We are subject to the cyclical nature of the semiconductor industry.

The semiconductor industry is highly cyclical and is characterized by constant and rapid technological change, rapid product obsolescence and price erosion, evolving standards, short product life cycles and wide fluctuations in product supply and demand. The industry is experiencing a significant downturn during the current global recession. These downturns have been characterized by diminished product demand, production overcapacity, high inventory levels and accelerated erosion of average selling prices. The current downturn and any future downturns could have a material adverse effect on our business and operating results. Furthermore, any upturn in the semiconductor industry could result in increased competition for access to third-party foundry and assembly capacity. We are dependent on the availability of this capacity to manufacture and assemble our RF receivers and RF receiver SoCs. None of our third-party foundry or assembly contractors has provided assurances that adequate capacity will be available to us in the future.

Our products must conform to industry standards in order to be accepted by end users in our markets.

Generally, our products comprise only a part of a communications device. All components of these devices must uniformly comply with industry standards in order to operate efficiently together. We depend on companies that provide other components of the devices to support prevailing industry standards. Many of these companies are significantly larger and more influential in driving industry standards than we are. Some industry standards may not be widely adopted or implemented uniformly, and competing standards may emerge that may be preferred by our customers or end users. If larger companies do not support the same industry standards that we do, or if competing standards emerge, market acceptance of our products could be adversely affected, which would harm our business.

Products for communications applications are based on industry standards that are continually evolving. Our ability to compete in the future will depend on our ability to identify and ensure compliance with these evolving industry standards. The emergence of new industry standards could render our products incompatible with products developed by other suppliers. As a result, we could be required to invest significant time and effort and to incur significant expense to redesign our products to ensure compliance with relevant standards. If our products are not in compliance with prevailing industry standards for a significant period of time, we could miss opportunities to achieve crucial design wins. We may not be successful in developing or using new technologies or in developing new products or product enhancements that achieve market acceptance. Our pursuit of necessary technological advances may require substantial time and expense.

Risks Relating to Our Class A Common Stock

The dual class structure of our common stock as contained in our charter documents will have the effect of allowing our founders, executive officers, employees and directors and their affiliates to limit your ability to influence corporate matters that you may consider unfavorable.

38

We sold Class A common stock in our initial public offering. Our founders, executive officers, directors and their affiliates and employees hold shares of our Class B common stock, which is not publicly traded. Until March 29, 2017, the dual class structure of our common stock will have the following effects with respect to the holders of our Class A common stock:

• allows the holders of our Class B common stock to have the sole right to elect two management directors to the Board of Directors;

• with respect to change of control matters, allows the holders of our Class B common stock to have ten votes per share compared to the holders of our Class A common stock who will have one vote per share on these matters; and

• with respect to the adoption of or amendments to our equity incentive plans, allows the holders of our Class B common stock to have ten votes per share compared to the holders of our Class A common stock who will have one vote per share on these matters, subject to certain limitations.

Thus, our dual class structure will limit your ability to influence corporate matters and, as a result, we may take actions that our stockholders do not view as beneficial, which may adversely affect the market price of our Class A common stock.

The concentration of our capital stock ownership with our founders, executive officers, will limit your ability to influence corporate matters and their interests may differ from other stockholders.

As of September 30, 2012, our founders, including our Chairman, President and Chief Executive Officer, Dr. Seendripu, together control approximately 21% of our outstanding capital stock, representing approximately 53% of the voting power of our outstanding capital stock with respect to change of control matters and the adoption of or amendment to our equity incentive plans. Dr. Seendripu and the other founders therefore have significant influence over the management and affairs of the Company and over all matters requiring stockholder approval, including the election of two Class B directors and significant corporate transactions, such as a merger or other sale of our Company or its assets, for the foreseeable future.

Our management team may invest or spend the proceeds from our initial public offering in ways with which you may not agree or in ways which may not yield a return.

The net proceeds from our initial public offering may be used for general corporate purposes, including working capital. We may also use a portion of the net proceeds to acquire complementary businesses, products, services or technologies. However, we do not have any agreements or commitments for any specific acquisitions at this time. Our management will have considerable discretion in the application of the net proceeds, and you will not have the opportunity, as part of your investment decision, to assess whether the proceeds are being used appropriately. The net proceeds may be used for corporate purposes that do not increase our operating results or market value. Until the net proceeds are used, they may be placed in investments that do not produce significant income or that may lose value.

Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us more difficult, limit attempts by our stockholders to replace or remove our current management and limit the market price of our Class A common stock.

Provisions in our certificate of incorporation and bylaws, as amended and restated, may have the effect of delaying or preventing a change of control or changes in our management. These provisions provide for the following:

• authorize our Board of Directors to issue, without further action by the stockholders, up to 25,000,000 shares of undesignated preferred stock;

• require that any action to be taken by our stockholders be effected at a duly called annual or special meeting and not by written consent;

• specify that special meetings of our stockholders can be called only by our Board of Directors, our Chairman of the Board of Directors, the President of the Company or by unanimous written consent of our directors appointed by the holders of Class B common stock;

• establish an advance notice procedure for stockholder approvals to be brought before an annual meeting of our stockholders, including proposed nominations of persons for election to our Board of Directors;

• establish that our Board of Directors is divided into three classes, Class I, Class II and Class III, with each class serving staggered terms and with one Class B director being elected to each of Classes II and III;

39

• provide for a dual class common stock structure, which provides our founders, current investors, executives and employees with significant influence over all matters requiring stockholder approval, including the election of directors and significant corporate transactions, such as a merger or other sale of our Company or its assets;

• provide that our directors may be removed only for cause;

• provide that vacancies on our Board of Directors may be filled only by a majority of directors then in office, even though less than a quorum, other than any vacancy in the two directorships reserved for the designees of the holders of Class B common stock, which may be filled only by the affirmative vote of the holders of a majority of the outstanding Class B common stock or by the remaining director elected by the Class B common stock (with the consent of founders holding a majority in interest of the Class B common stock over which the founders then exercise voting control);

• specify that no stockholder is permitted to cumulate votes at any election of directors; and

• require supermajority votes of the holders of our common stock to amend specified provisions of our charter documents.

These provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our Board of Directors, which is responsible for appointing the members of our management. In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which generally prohibits a Delaware corporation from engaging in any of a broad range of business combinations with any “interested” stockholder for a period of three years following the date on which the stockholder became an “interested” stockholder.

Our share price may be volatile as a result of limited trading volume and other factors.

Our shares of Class A common stock began trading on the New York Stock Exchange in March 2010. An active public market for our shares on the New York Stock Exchange may not be sustained. In particular, limited trading volumes and liquidity may limit the ability of stockholders to purchase or sell our common stock in the amounts and at the times they wish. Trading volume in our Class A common stock tends to be modest relative to our total outstanding shares, and the price of our Class A common stock may fluctuate substantially (particularly in percentage terms) without regard to news about us or general trends in the stock market. An inactive market may also impair our ability to raise capital to continue to fund operations by selling shares and may impair our ability to acquire other companies or technologies by using our shares as consideration.

In addition, the trading price of our Class A common stock could become highly volatile and could be subject to wide fluctuations in response to various factors, some of which are beyond our control. These factors include those discussed in this “Risk Factors” section of this Annual Report on Form 10-K and others such as:

• actual or anticipated fluctuations in our financial condition and operating results;

• overall conditions in the semiconductor market;

• addition or loss of significant customers;

• changes in laws or regulations applicable to our products;

• actual or anticipated changes in our growth rate relative to our competitors;

• announcements of technological innovations by us or our competitors;

• announcements by us or our competitors of significant acquisitions, strategic partnerships, joint ventures or capital commitments;

• additions or departures of key personnel;

• competition from existing products or new products that may emerge;

• issuance of new or updated research or reports by securities analysts;

• fluctuations in the valuation of companies perceived by investors to be comparable to us;

• disputes or other developments related to proprietary rights, including patents, litigation matters and our ability to obtain intellectual property protection for our technologies;

40

• announcement or expectation of additional financing efforts;

• sales of our Class A or Class B common stock by us or our stockholders;

• share price and volume fluctuations attributable to inconsistent trading volume levels of our shares; and

• general economic and market conditions.

Furthermore, the stock markets recently have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many companies. These fluctuations often have been unrelated or disproportionate to the operating performance of those companies. These broad market and industry fluctuations, as well as general economic, political and market conditions such as recessions, interest rate changes or international currency fluctuations, may negatively impact the market price of our Class A common stock. In the past, companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. We may be the target of this type of litigation in the future. Securities litigation against us could result in substantial costs and divert our management’s attention from other business concerns, which could seriously harm our business.

If securities or industry analysts do not publish research or reports about our business, or publish negative reports about our business, especially due to our dual-class voting structure, our share price and trading volume could decline.

The trading market for our Class A common stock depends in part on the research and reports that securities or industry analysts publish about us or our business, especially with respect to our unique dual-class voting structure as to the election of directors, change of control matters and matters related to our equity incentive plans. We do not have any control over these analysts. If one or more of the analysts who cover us downgrade our shares or change their opinion of our shares, our share price would likely decline. If one or more of these analysts cease coverage of our Company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which could cause our share price or trading volume to decline.

Future sales of our Class A common stock in the public market could cause our share price to decline.

Sales of a substantial number of shares of our Class A common stock in the public market, or the perception that these sales might occur, could depress the market price of our Class A common stock and could impair our ability to raise capital through the sale of additional equity securities. As of September 30, 2012, we had 22.6 million shares of Class A common stock and 10.2 million shares of Class B common stock outstanding.

All shares of Class A common stock are freely tradable without restrictions or further registration under the Securities Act of 1933, as amended, or the Securities Act, except for any shares held by our affiliates as defined in Rule 144 under the Securities Act.

The holders of 2.4 million shares of Class B common stock, or 7% of our total outstanding Class A and Class B common stock, are entitled to rights with respect to registration of these shares under the Securities Act pursuant to a registration rights agreement. Shares of our Class B common stock automatically will convert into shares of our Class A common stock upon any sale or transfer, whether or not for value, except for certain transfers described in our amended and restated certificate of incorporation. If these holders of our Class B common stock, by exercising their registration rights, sell a large number of shares, they could adversely affect the market price for our Class A common stock. If we file a registration statement for the purposes of selling additional shares to raise capital and are required to include shares held by these holders pursuant to the exercise of their registration rights, our ability to raise capital may be impaired. We filed registration statements on Form S-8 under the Securities Act to register 13.3 million shares of our Class A common stock for issuance under our 2010 Equity Incentive Plan and 2010 Employee Stock Purchase Plan. These shares may be freely sold in the public market upon issuance and once vested, subject to other restrictions provided under the terms of the applicable plan and/or the option agreements entered into with option holders.

41

The requirements of being a public company may strain our resources, divert management’s attention and affect our ability to attract and retain qualified board members.

As a public company, we are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended, or the Exchange Act, the Sarbanes-Oxley Act, the listing requirements of the NYSE and other applicable securities rules and regulations. None of our senior executives has managed a public company prior to our becoming a public company in March 2010. Compliance with these rules and regulations have increased our legal and financial compliance costs, made some activities more difficult, time-consuming or costly and increased the demand on our systems and resources. The Exchange Act requires, among other things, that we file annual, quarterly and current reports with respect to our business and financial condition. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal control over financial reporting. In order to maintain and, if required, improve our disclosure controls and procedures and internal control over financial reporting to meet this standard, significant resources and management oversight may be required. As a result, management’s attention may be diverted from other business concerns, which could have a material adverse effect on our business, financial condition and results of operations. Although we have already hired additional staff to comply with these requirements, we may need to hire more employees in the future, which will increase our costs and expenses.

In addition, changing laws, regulations and standards relating to corporate governance and public disclosure are creating uncertainty for public companies, increasing legal and financial compliance costs and making some activities more time consuming. These laws, regulations and standards are subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. We intend to invest resources to comply with evolving laws, regulations and standards, and this investment may result in increased general and administrative expenses and a diversion of management’s time and attention from revenue-generating activities to compliance activities. If our efforts to comply with new laws, regulations and standards differ from the activities intended by regulatory or governing bodies due to ambiguities related to practice, regulatory authorities may initiate legal proceedings against us and our business may be harmed.

We also expect that being a newly public company and these new rules and regulations will make it more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These factors could also make it more difficult for us to attract and retain qualified members of our Board of Directors, particularly to serve on our audit committee and compensation committee, and qualified executive officers.

We do not intend to pay dividends for the foreseeable future.

We have never declared or paid any cash dividends on our common stock and do not intend to pay any cash dividends in the foreseeable future. We anticipate that we will retain all of our future earnings for use in the development of our business and for general corporate purposes. Any determination to pay dividends in the future will be at the discretion of our Board of Directors. Accordingly, investors must rely on sales of their Class A common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investments.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Recent Sales of Unregistered Securities

In the fiscal quarter ended September 30, 2012, we issued an aggregate of 454,833 shares of our Class B common stock to certain employees upon the exercise of options awarded under our 2004 Stock Plan. We received aggregate proceeds of approximately $0.8 million in the fiscal quarter ended September 30, 2012 as a result of the exercise of these options. We believe these transactions were exempt from the registration requirements of the Securities Act in reliance on Rule 701 thereunder as transactions pursuant to compensatory benefit plans and contracts relating to compensation as provided under Rule 701. As of September 30, 2012, options to purchase an aggregate of 1,519,139 shares of our Class B common stock remain outstanding. All issuances of shares of our Class B common stock pursuant to the exercise of these options will be made in reliance on Rule 701. All option grants made under the 2004 Stock Plan were made prior to the effectiveness of our initial public offering. No further option grants will be made under our 2004 Stock Plan.

The sales and issuances of securities in the transactions described above were deemed to be exempt from registration under the Securities Act of 1933, as amended, in reliance upon Rule 701 promulgated under Section 3(b) of the Securities Act of 1933, as amended, as transactions pursuant to compensatory benefit plans and contracts relating to compensation as provided under Rule 701. The recipients of securities in each transaction represented their intentions to acquire the securities for investment only and not with a view to or for sale in connection with any distribution thereof and appropriate legends were affixed to the securities issued in these transactions. All recipients had adequate access, through employment or other relationships, to information about us. All certificates representing the securities issued in these transactions included appropriate legends setting forth that the securities had not been offered or sold pursuant to a registration statement and describing the applicable restrictions on transfer of the securities. There were no underwriters employed in connection with any of the transactions set forth above. Each share of our Class B common stock is convertible at any time at the option of the holder into one share of our Class A common stock. In addition, each share of our Class B common stock will convert automatically into one share of Class A common stock upon any transfer, whether or not for value, except for certain transfers described in our certificate of incorporation.

As of September 30, 2012, the Company held 7 corporate debt securities with an aggregate fair value of $13,090 that were in an unrealized loss position for less than 12 months. The gross unrealized losses of $4 at September 30, 2012 represent temporary impairments on corporate debt securities related to multiple issuers, and were primarily caused by fluctuations in U.S. interest rates. The Company has determined that the gross unrealized losses on these securities at September 30, 2012 are temporary in nature. The Company evaluates securities for other-than-temporary impairment on a quarterly basis. Impairment is evaluated considering numerous factors, and their relative significance varies depending on the situation. Factors considered include the length of time and extent to which fair value has been less than the cost basis, the financial condition and near-term prospects of the issuer, and our intent and ability to hold the security in order to allow for an anticipated recovery in fair value.

All of the Company’s long-term available-for-sale securities were due between one and two years as of September 30, 2012.

The fair values of the Company’s financial instruments are the amounts that would be received in an asset sale or paid to transfer a liability in an orderly transaction between unaffiliated market participants and are recorded using a hierarchal disclosure framework based upon the level of subjectivity of the inputs used in measuring assets and liabilities. The levels are described below:

Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities.

Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data.

Level 3: Unobservable inputs are used when little or no market data is available.

The Company classifies its financial instruments within Level 1 or Level 2 of the fair value hierarchy. This is because the Company values financial instruments using quoted market prices or alternate pricing sources and models utilizing market observable inputs. The Company held no Level 3 financial instruments as of September 30, 2012 and December 31, 2011.

The following table presents a summary of the Company’s financial instruments that are measured on a recurring basis:

			Fair Value Measurements at September 30, 2012
	Balance at September 30, 2012		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)

Net Income (Loss) Per Share

Net Income (Loss) Per Share

2. Net Income (Loss) Per Share

Net income (loss) per share is computed as required by the accounting standard for earnings per share, or EPS. Basic EPS is calculated by dividing net income (loss) by the weighted-average number of common shares outstanding for the period, without consideration for common stock equivalents. Diluted EPS is computed by dividing net income (loss) by the weighted-average number of common shares outstanding for the period and the weighted-average number of dilutive common stock equivalents outstanding for the period determined using the treasury-stock method. For purposes of this calculation, common stock options, restricted stock units and restricted stock awards are considered to be common stock equivalents and are only included in the calculation of diluted EPS when their effect is dilutive.

The Company has two classes of stock outstanding, Class A common stock and Class B common stock. The economic rights of the Class A common stock and Class B common stock, including rights in connection with dividends and payments upon a liquidation or merger are identical, and the Class A common stock and Class B common stock will be treated equally, identically and ratably, unless differential treatment is approved by the Class A common stock and Class B common stock, each voting separately as a class. The Company computes basic earnings per share by dividing net income (loss) by the weighted average number of shares of Class A and Class B common stock outstanding during the period. For diluted earnings per share, the Company divides net income (loss) by the sum of the weighted average number of shares of Class A and Class B common stock outstanding and the potential number of shares of dilutive Class A and Class B common stock outstanding during the period.

Organization and Summary of Significant Accounting Policies

1. Organization and Summary of Significant Accounting Policies

Description of Business

MaxLinear, Inc. (the Company) was incorporated in Delaware in September 2003. The Company is a provider of integrated, radio-frequency and mixed-signal semiconductor solutions for broadband communication applications whose customers include module makers, original equipment manufacturers, or OEMs, and original design manufacturers, or ODMs, who incorporate the Company’s products in a wide range of electronic devices including mobile handsets, cable and terrestrial set top boxes, DOCSIS data and voice gateways, televisions, personal computers and netbooks and automotive entertainment applications. The Company is a fabless semiconductor company focusing its resources on the design, sales and marketing of its products.

Basis of Presentation and Principles of Consolidation

The unaudited consolidated financial statements include the accounts of MaxLinear, Inc. and its wholly owned subsidiaries. All intercompany transactions and investments have been eliminated in consolidation.

The functional currency of certain foreign subsidiaries is the local currency. Accordingly, assets and liabilities of these foreign subsidiaries are translated at the current exchange rate at the balance sheet date and historical rates for equity. Revenue and expense components are translated at weighted average exchange rates in effect during the period. Gains and losses resulting from foreign currency translation are included as a component of stockholders’ equity. Foreign currency transaction gains and losses are included in the results of operations and, to date, have not been significant.

The Company has prepared the accompanying unaudited consolidated financial statements in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and disclosures required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments, which include only normal recurring adjustments, considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2012 are not necessarily indicative of the results that may be expected for the year ending December 31, 2012. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes thereto for the year ended December 31, 2011, included in the Annual Report on Form 10-K filed by the Company with the Securities and Exchange Commission (SEC) on March 14, 2012.

Use of Estimates

The preparation of unaudited consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the unaudited consolidated financial statements and accompanying notes of the unaudited consolidated financial statements. Actual results could differ from those estimates.

Revenue Recognition

Revenue is generated from sales of the Company’s integrated circuits. The Company recognizes revenue when all of the following criteria are met: 1) there is persuasive evidence that an arrangement exists, 2) delivery of goods has occurred, 3) the sales price is fixed or determinable and 4) collectibility is reasonably assured. Title to product transfers to customers either when it is shipped to or received by the customer, based on the terms of the specific agreement with the customer.

Revenue is recorded based on the facts at the time of sale. Transactions for which the Company cannot reliably estimate the amount that will ultimately be collected at the time the product has shipped and title has transferred to the customer are deferred until the amount that is probable of collection can be determined. Items that are considered when determining the amounts that will be ultimately collected are: a customer’s overall creditworthiness and payment history; customer rights to return unsold product; customer rights to price protection; customer payment terms conditioned on sale or use of product by the customer; or extended payment terms granted to a customer.

A portion of the Company’s revenues are generated from sales made through distributors under agreements allowing for pricing credits and/or stock rotation rights of return. Revenues from the Company’s distributors accounted for 38% and 40% of net revenue for the three and nine months ended September 30, 2012, respectively. Revenues from the Company’s distributors accounted for 71% and 72% of our net revenue in the three and nine months ended September 30, 2011, respectively. Pricing credits to the Company’s distributors may result from its price protection and unit rebate provisions, among other factors. These pricing credits and/or stock rotation rights prevent the Company from being able to reliably estimate the final sales price of the inventory sold and the amount of inventory that could be returned pursuant to these agreements. As a result, for sales to distributors, the Company has determined that it does not meet all of the required revenue recognition criteria at the time it delivers its products to distributors as the final sales price is not fixed or determinable. For these distributor transactions, revenue is not recognized until product is shipped to the end customer and the amount that will ultimately be collected is fixed or determinable. Upon shipment of product to these distributors, title to the inventory transfers to the distributor and the distributor is invoiced, generally with 30 day terms. On shipments to the Company’s distributors where revenue is not recognized, the Company records a trade receivable for the selling price as there is a legally enforceable right to payment, relieving the inventory for the carrying value of goods shipped since legal title has passed to the distributor, and records the corresponding gross profit in the consolidated balance sheet as a component of deferred revenue and deferred profit, representing the difference between the receivable recorded and the cost of inventory shipped. Future pricing credits and/or stock rotation rights from the Company’s distributors may result in the realization of a different amount of profit included in the Company’s future consolidated statements of operations than the amount recorded as deferred profit in the Company’s consolidated balance sheets.

The Company records reductions in revenue for estimated pricing adjustments related to price protection and unit rebate agreements with the Company’s end customers in the same period that the related revenue is recorded. Price protection pricing adjustments are recorded at the time of sale as a reduction to revenue and an increase in the Company’s accrued liabilities. The Company may enter into unit rebate agreements with end customers based on volume purchases. The Company estimates that all of the unit rebates will be achieved based on the history of these programs, reduces the average selling price of the product sold under the rebate program and defers revenue for the difference between the amount billed to the customer and the adjusted average selling price. Once the targeted level is achieved, the deferred revenue is recognized as revenue as rebated products are shipped to the end customer. Deferred revenue associated with rebate programs is included in deferred revenue and deferred profit in the consolidated balance sheet.

Stock Repurchase

The Company records the excess of repurchase price over par value to retained earnings upon repurchase and retirement of shares of its Class A common stock and Class B common stock in accordance with the accounting standard for equity.

Recent Accounting Pronouncements

Effective January 1, 2012, the Company adopted the Financial Accounting Standards Board’s, or FASB, updated guidance on fair value measurements that clarifies the application of existing guidance and disclosure requirements, changes certain fair value measurement principles and requires additional disclosures about fair value measurements. The Company’s adoption of the updated guidance did not have a material impact on its consolidated financial statements.

Effective January 1, 2012, the Company adopted the FASB’s new standard regarding the presentation of comprehensive income. The new standard requires the presentation of comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The new standard also requires presentation on the face of the financial statements of reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement where the components of net income and the components of other comprehensive income are presented. The Company’s adoption of the new standard did not have a material impact on its consolidated financial statements.

Income Taxes

6. Income Taxes

In order to determine the quarterly provision for income taxes, the Company used an estimated annual effective tax rate, which is based on expected annual income and statutory tax rates in the various jurisdictions in which the Company operates. Certain significant or unusual items are separately recognized in the quarter during which they occur and can be a source of variability in the effective tax rates from quarter to quarter.

The Company recorded a provision for income taxes of $44 and $235 for the three and nine months ended September 30, 2012, respectively. The Company recorded a provision for income taxes of $8,227 and $6,710 for the three and nine months ended September 30, 2011, respectively. The provision for income taxes for the three and nine months ended September 30, 2012 primarily relates to income tax in certain foreign jurisdictions. The provision for income taxes for the three and nine months ended September 30, 2011 primarily relates to the establishment of a valuation allowance against the Company’s net federal deferred tax asset in the third quarter of 2011.

During the nine months ended September 30, 2012, the Company’s unrecognized tax benefits increased by $151. The Company does not anticipate its unrecognized tax benefits will change significantly over the next 12 months. There were no accrued interest and penalties associated with uncertain tax positions as of September 30, 2012.

Stock-Based Compensation and Employee Benefit Plans

5. Stock-Based Compensation and Employee Benefit Plans

Stock-Based Compensation

The Company uses the Black-Scholes valuation model to calculate the fair value of stock options and employee stock purchase rights granted to employees. The Company calculates the fair value of restricted stock units, or RSUs, and restricted stock awards, or RSAs, based on the fair market value of our Class A common stock on the grant date. The weighted-average grant date fair value per share of the RSUs and RSAs granted in the nine months ended September 30, 2012 was $5.87. The weighted-average grant date fair value per share of the RSUs granted in the nine months ended September 30, 2011 was $8.53. No RSAs were granted during the nine months ended September 30, 2011.

The fair values of stock options and employee stock purchase rights were estimated at their respective grant date using the following assumptions:

Stock Options

	Nine Months Ended September 30,
	2012			2011
Weighted-average grant date fair value per share	$	2.37		$	4.26
Risk-free interest rate		0.88	%		2.01	%
Dividend yield		—			—
Expected life (years)		4.84			5.05
Volatility		55.91	%		51.83	%
Employee Stock Purchase Rights
	Nine Months Ended September 30,
	2012			2011
Weighted-average grant date fair value per share	$	1.28		$	2.46
Risk-free interest rate		0.15	%		0.07	%
Dividend yield		—			—
Expected life (years)		0.50			0.50
Volatility		46.60	%		45.70	%

The risk-free interest rate assumption was based on the United States Treasury’s rates for U.S. Treasury zero-coupon bonds with maturities similar to those of the expected term of the award being valued. The assumed dividend yield was based on the Company’s expectation of not paying dividends in the foreseeable future. The weighted-average expected life of options was calculated using the simplified method as prescribed by guidance provided by the SEC. This decision was based on the lack of relevant historical data due to the Company’s limited historical experience. In addition, due to the Company’s limited historical data, the estimated volatility incorporates the historical volatility of comparable companies whose share prices are publicly available.

The Company recognized stock-based compensation in the statements of operations as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2012		2011		2012		2011
Cost of net revenue	$	23	$	15	$	61	$	38

	$	2,609	$	2,169	$	7,165	$	5,206

Exchange Offer

In May 2012, the Company completed an offer to exchange (the “Exchange Offer”) for restricted stock units (RSUs), certain outstanding options to purchase shares of the Company’s Class A common stock and shares of the Company’s Class B common stock. Pursuant to the terms and conditions of the Exchange Offer, the Company accepted for exchange options to purchase 1,327 shares of the Company’s Class A common stock and 591 shares of the Company’s Class B common stock. All surrendered options were cancelled, and immediately thereafter, the Company issued a total of 959 restricted stock units in exchange therefor, pursuant to the terms of the Exchange Offer. The Company accounted for the Exchange Offer as a modification of the original options as required by the accounting standard for stock-based compensation. The total Exchange Offer stock-based compensation is $7.3 million, including the incremental value attributed to the modified options of $1.8 million, which will be recognized over the vesting period of the new RSUs.

Stock Repurchase

In August 2012, the Company’s board of directors and the audit committee of the Company’s board of directors approved the repurchase and retirement of 1,152 shares of the Company’s Class A common stock and the repurchase and retirement of 500 shares of the Company’s Class B common stock. The Company effected the repurchases pursuant to a stock repurchase agreement. The per share repurchase price for both Class A and Class B shares repurchased was the closing price of the Company’s Class A common stock in trading on the New York Stock Exchange on August 21, 2012, the date of the agreement. The aggregate repurchase price was $9.2 million. Other than the transactions disclosed above, the Company’s board of directors has not authorized any stock repurchase program, and the Company has no current plans to effect any open-market purchases of its Class A common stock or other repurchases of its Class B common stock from two of its shareholders.

Employee Benefit Plans

2010 Equity Incentive Plan

The 2010 Plan provides for the grant of incentive stock options, non-statutory stock options, restricted stock awards, restricted stock unit awards, stock appreciation rights, performance-based stock awards, and other forms of equity compensation, or collectively, stock awards. The exercise price for an incentive or a non-statutory stock option cannot be less than 100% of the fair market value of the Company’s Class A common stock on the date of grant. Options granted will generally vest over a four-year period and the term can be from seven to ten years.

On January 1, 2012, 1,329 shares of Class A common stock were automatically added to the shares authorized for issuance under the 2010 Plan pursuant to an “evergreen” provision contained in the 2010 Plan.

2010 Employee Stock Purchase Plan

The 2010 Employee Stock Purchase Plan, or ESPP, is implemented through a series of offerings of purchase rights to eligible employees. Generally, all regular employees, including executive officers, employed by the Company may participate in the ESPP and may contribute up to 15% of their earnings for the purchase of the Company’s common stock under the ESPP. Unless otherwise determined by the Company’s board of directors, Class A common stock will be purchased for accounts of employees participating in the ESPP at a price per share equal to the lower of (a) 85% of the fair market value of a share of the Company’s Class A common stock on the first date of an offering or (b) 85% of the fair market value of a share of the Company’s Class A common stock on the date of purchase.

On January 1, 2012, 415 shares of Class A common stock were automatically added to the shares authorized for issuance under the ESPP pursuant to an “evergreen” provision contained in the ESPP.

Common Stock

At September 30, 2012, the Company had 500 million authorized shares of Class A common stock and 500 million authorized shares of Class B common stock. Holders of the Company’s Class A and Class B common stock have identical voting rights, except that holders of Class A common stock are entitled to one vote per share and holders of Class B common stock are entitled to ten votes per share with respect to transactions that would result in a change of control of the Company or that relate to the Company’s equity incentive plans. In addition, holders of Class B common stock have the exclusive right to elect two members of the Company’s Board of Directors, each referred to as a Class B Director. The shares of Class B common stock are not publicly traded. Each share of Class B common stock is convertible at any time at the option of the holder into one share of Class A common stock and in most instances automatically converts upon sale or other transfer.

Silicon Labs Litigation

On May 13, 2012, the Company filed a declaratory judgment complaint in United States District Court for the Southern District of California against Silicon Laboratories Inc., or Silicon Labs, as defendant seeking an order that the Company’s CMOS hybrid tuner products, such as the MxL301 and MxL601, do not infringe nineteen (19) patents owned by Silicon Labs. The declaratory judgment complaint further seeks a ruling that the defendant’s patents are invalid. Silicon Labs has filed counterclaims for infringement on five (5) of the nineteen (19) patents and one (1) additional Silicon Labs patent. On September 13, 2012, Silicon Labs filed a motion for preliminary injunction requesting an injunction on the Company’s MxL601 product based upon alleged infringement of U.S. Patent No. 7,200,364. The hearing on the preliminary injunction motion is set for November 2, 2012. No trial date has been set.

On July 17, 2012, Silicon Labs filed a complaint for patent infringement against the Company in United States District Court for the Southern District of California. The Silicon Labs complaint asserts that a wide range of the Company’s products infringe a single Silicon Labs patent, U.S. Patent No. 7,035,607, or the ‘607 patent. The ‘607 patent is related to several of the nineteen (19) patents on which the Company filed a declaratory judgment action against Silicon Labs. The Silicon Labs complaint seeks damages and injunctive relief against the Company’s products. The Company has filed counterclaims for infringement on three (3) patents owned by the Company – United States Patent Nos. 7,362,178; 8,198,940; and 7,778,613. Silicon Labs has filed a motion to dismiss or transfer the Company’s counterclaims for infringement to the United States District Court for the Western District of Texas. A trial date has been set for February 11, 2014.

On July 30, 2012, Silicon Labs filed a declaratory judgment complaint in United States District Court for the Western District of Texas against the Company seeking an order that Silicon Labs’ products do not infringe the three (3) patents owned by the Company asserted as counterclaims in the second Southern District of California action. The declaratory judgment complaint further seeks a ruling that the patents are invalid. The Company has filed a motion to dismiss for lack of personal jurisdiction, and the Court has granted limited jurisdictional discovery related to the issue. No trial date has been set.

The Company has not recorded any accrual for loss contingencies associated with Silicon Labs litigation; determined that an unfavorable outcome is probable or reasonably possible; or determined that the amount or range of any possible loss is reasonably estimable.

Export Compliance Matter

As noted in the Company’s Current Report on Form 8-K filed on February 7, 2012, in the first quarter of 2012, the Company determined that it may have taken actions that could constitute facilitation (within the meaning of applicable sanctions and export control laws) of shipments of foreign produced products to Iran or taken other actions that may be in violation of U.S. export control and economic sanctions laws. Specifically, certain of the Company’s tuner products, which are foreign produced and not subject to U.S. export controls, were included in set-top converter boxes produced by set-top box manufacturers in Asia to permit conversion of digital television signals to analog signals in international markets, including Iran, using the DVB-T, or Digital Video Broadcasting – Terrestrial, broadcast standard. The DVB-T standard is used in most of Europe, Asia (excluding China), Australia, and Africa as well as in parts of the Middle East, including Iran. While the underlying shipment of the Company’s tuners into Iran by foreign manufacturers of these set-top boxes may have been lawful, the Company may have violated applicable sanctions and export control laws without the proper U.S. Government authorization.

The Company initially identified these potential violations internally, rather than as a result of a third-party audit or government investigation, and upon learning of these potential violations, the Company’s audit committee promptly retained outside counsel to conduct a review of the Company’s sanctions and export control compliance. On February 7, 2012, the Company made voluntary initial filings with the Office of Foreign Assets Control of the United States Department of the Treasury, or OFAC, and with the Bureau of Industry and Security of the United States Department of Commerce, or BIS, notifying these regulatory agencies that the Company was conducting a review of export control matters and that the Company would submit any supplemental voluntary self-disclosures once the Company’s internal review was complete. The initial stage of the review was concluded in March 2012. Subsequently, the Company also learned that the Company was not in full compliance with BIS’s deemed export rule which requires, in some circumstances, that the companies obtain a deemed export license from BIS for employment of certain foreign nationals even if, as was the Company’s situation, the Company had obtained an H1-B visa prior to employing the individual. The Company has now applied for such license with respect to the subject employee.

In connection with its March 2012 review, the Company’s audit committee determined that the Company’s management team lacked sufficient familiarity with and understanding of export control and sanctions laws and their applicability to the Company’s products and services. The Company’s audit committee concluded that the Company’s management team did not intentionally or knowingly violate applicable sanctions and export control laws.

The Company submitted final voluntary disclosures to OFAC on June 1, 2012 and BIS on June 15, 2012 and July 11, 2012. On September 27, 2012, OFAC closed out the Company’s Voluntary Self Disclosure with the issuance of a cautionary letter, and no monetary or other penalty was imposed against the Company. The BIS Voluntary Self Disclosure remains pending and the Company informed BIS that OFAC closed out its case with a cautionary letter.

Penalties and potential criminal enforcement actions could be imposed against the Company and/or the Company’s management and certain of the Company’s employees. The Company cannot predict when BIS will complete its review of the Company’s submissions, and resolution of the BIS matter could take substantial time and require substantial expenditure and management resources, either of which could be harmful to the Company’s business and operating results.

Any fines that BIS may impose on the Company could be material to the Company’s operating results in the period in which they are imposed and could have a material adverse effect on the Company’s financial condition. The maximum civil monetary penalty for each violation is up to $250 or twice the value of the transaction, whichever is greater. In the three and nine months ended September 30, 2012, the Company reduced its previously recorded OFAC penalties and fines by $625 reflected in selling, general, and administrative expense. Based upon facts known to the Company to date, the Company has retained a total provision of $250 for this export compliance matter, representing management’s estimated exposure for potential BIS fines in accordance with applicable accounting literature. Should additional facts be discovered in the future and/or should actual fines or other penalties differ from the Company’s estimates, its business, operating results, and financial condition could be materially and negatively affected. In that regard, the Company cannot guarantee that BIS will agree with its assessments of the quantity and nature of the potential violations. As a result, BIS could seek to impose higher fines and penalties than those the Company has estimated to date, and the Company could incur significant additional legal expenses in response. As a result of increased awareness relative to U.S. export control and economic sanction laws relating to the sale of the Company’s products, the Company has implemented additional export control compliance management oversight and has undertaken remedial measures to reduce the risk of similar events occurring in the future.

The Company is a provider of integrated, radio-frequency and mixed-signal semiconductor solutions for broadband communication applications whose customers include module makers, original equipment manufacturers, or OEMs, and original design manufacturers, or ODMs, who incorporate the Company’s products in a wide range of electronic devices including mobile handsets, cable and terrestrial set top boxes, DOCSIS data and voice gateways, televisions, personal computers and netbooks and automotive entertainment applications. The Company is a fabless semiconductor company focusing its resources on the design, sales and marketing of its products

Basis of Presentation and Principles of Consolidation

Basis of Presentation and Principles of Consolidation

The unaudited consolidated financial statements include the accounts of MaxLinear, Inc. and its wholly owned subsidiaries. All intercompany transactions and investments have been eliminated in consolidation.

The functional currency of certain foreign subsidiaries is the local currency. Accordingly, assets and liabilities of these foreign subsidiaries are translated at the current exchange rate at the balance sheet date and historical rates for equity. Revenue and expense components are translated at weighted average exchange rates in effect during the period. Gains and losses resulting from foreign currency translation are included as a component of stockholders’ equity. Foreign currency transaction gains and losses are included in the results of operations and, to date, have not been significant.

The Company has prepared the accompanying unaudited consolidated financial statements in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and disclosures required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments, which include only normal recurring adjustments, considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2012 are not necessarily indicative of the results that may be expected for the year ending December 31, 2012. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes thereto for the year ended December 31, 2011, included in the Annual Report on Form 10-K filed by the Company with the Securities and Exchange Commission (SEC) on March 14, 2012.

Use of Estimates

Use of Estimates

The preparation of unaudited consolidated financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the unaudited consolidated financial statements and accompanying notes of the unaudited consolidated financial statements. Actual results could differ from those estimates.

Revenue Recognition

Revenue Recognition

Revenue is generated from sales of the Company’s integrated circuits. The Company recognizes revenue when all of the following criteria are met: 1) there is persuasive evidence that an arrangement exists, 2) delivery of goods has occurred, 3) the sales price is fixed or determinable and 4) collectibility is reasonably assured. Title to product transfers to customers either when it is shipped to or received by the customer, based on the terms of the specific agreement with the customer.

Revenue is recorded based on the facts at the time of sale. Transactions for which the Company cannot reliably estimate the amount that will ultimately be collected at the time the product has shipped and title has transferred to the customer are deferred until the amount that is probable of collection can be determined. Items that are considered when determining the amounts that will be ultimately collected are: a customer’s overall creditworthiness and payment history; customer rights to return unsold product; customer rights to price protection; customer payment terms conditioned on sale or use of product by the customer; or extended payment terms granted to a customer.

A portion of the Company’s revenues are generated from sales made through distributors under agreements allowing for pricing credits and/or stock rotation rights of return. Revenues from the Company’s distributors accounted for 38% and 40% of net revenue for the three and nine months ended September 30, 2012, respectively. Revenues from the Company’s distributors accounted for 71% and 72% of our net revenue in the three and nine months ended September 30, 2011, respectively. Pricing credits to the Company’s distributors may result from its price protection and unit rebate provisions, among other factors. These pricing credits and/or stock rotation rights prevent the Company from being able to reliably estimate the final sales price of the inventory sold and the amount of inventory that could be returned pursuant to these agreements. As a result, for sales to distributors, the Company has determined that it does not meet all of the required revenue recognition criteria at the time it delivers its products to distributors as the final sales price is not fixed or determinable. For these distributor transactions, revenue is not recognized until product is shipped to the end customer and the amount that will ultimately be collected is fixed or determinable. Upon shipment of product to these distributors, title to the inventory transfers to the distributor and the distributor is invoiced, generally with 30 day terms. On shipments to the Company’s distributors where revenue is not recognized, the Company records a trade receivable for the selling price as there is a legally enforceable right to payment, relieving the inventory for the carrying value of goods shipped since legal title has passed to the distributor, and records the corresponding gross profit in the consolidated balance sheet as a component of deferred revenue and deferred profit, representing the difference between the receivable recorded and the cost of inventory shipped. Future pricing credits and/or stock rotation rights from the Company’s distributors may result in the realization of a different amount of profit included in the Company’s future consolidated statements of operations than the amount recorded as deferred profit in the Company’s consolidated balance sheets.

The Company records reductions in revenue for estimated pricing adjustments related to price protection and unit rebate agreements with the Company’s end customers in the same period that the related revenue is recorded. Price protection pricing adjustments are recorded at the time of sale as a reduction to revenue and an increase in the Company’s accrued liabilities. The Company may enter into unit rebate agreements with end customers based on volume purchases. The Company estimates that all of the unit rebates will be achieved based on the history of these programs, reduces the average selling price of the product sold under the rebate program and defers revenue for the difference between the amount billed to the customer and the adjusted average selling price. Once the targeted level is achieved, the deferred revenue is recognized as revenue as rebated products are shipped to the end customer. Deferred revenue associated with rebate programs is included in deferred revenue and deferred profit in the consolidated balance sheet.

Stock Repurchase

Stock Repurchase

The Company records the excess of repurchase price over par value to retained earnings upon repurchase and retirement of shares of its Class A common stock and Class B common stock in accordance with the accounting standard for equity.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

Effective January 1, 2012, the Company adopted the Financial Accounting Standards Board’s, or FASB, updated guidance on fair value measurements that clarifies the application of existing guidance and disclosure requirements, changes certain fair value measurement principles and requires additional disclosures about fair value measurements. The Company’s adoption of the updated guidance did not have a material impact on its consolidated financial statements.

Effective January 1, 2012, the Company adopted the FASB’s new standard regarding the presentation of comprehensive income. The new standard requires the presentation of comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. The new standard also requires presentation on the face of the financial statements of reclassification adjustments for items that are reclassified from other comprehensive income to net income in the statement where the components of net income and the components of other comprehensive income are presented. The Company’s adoption of the new standard did not have a material impact on its consolidated financial statements.
