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 integrated circuits for broadband communication and data center, metro, and long-haul transport network 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 cable and terrestrial and satellite set top boxes, DOCSIS data and voice gateways, hybrid analog and digital televisions, satellite low-noise blocker transponders or outdoor units and optical modules for data center, metro, and long-haul transport network applications. The Company is a fabless semiconductor company focusing its resources on the design, sales and marketing of its products.

Acquisition of Entropic Communications, Inc.

On April 30, 2015, the Company completed its acquisition of Entropic Communications, Inc. (Entropic). Pursuant to the terms of the merger agreement dated as of February 3, 2015, by and among the Company, Entropic, and two wholly-owned subsidiaries of the Company, all of the Entropic outstanding shares were converted into the right to receive consideration consisting of cash and shares of the Company’s Class A common stock. The Company paid an aggregate of $111.1 million and issued an aggregate of 20.4 million shares of the Company’s Class A common stock, to the stockholders of Entropic. In addition, the Company assumed all outstanding Entropic stock options and unvested restricted stock units that were held by continuing service providers (as defined in the merger agreement). The Company used Entropic’s cash and cash equivalents to fund a significant portion of the cash portion of the merger consideration and, to a lesser extent, its own cash and cash equivalents. The Company has made all of the material remaining disclosures required by ASC 805-10-50-2, Business Combinations. See Note 3.

In connection with the Company’s acquisition of Entropic and to address issues primarily relating to the integration of the Company and Entropic businesses, the Company terminated the employment of  73 Entropic employees during the nine months endedSeptember 30, 2015. See Note 4.

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.

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, or GAAP, for complete financial statements. In the opinion of management, all adjustments, which include all normal recurring adjustments, considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015. 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, 2014 included in the Annual Report on Form 10-K filed by the Company with the Securities and Exchange Commission, or SEC, on February 23, 2015, as amended by Amendment No. 1 on Form 10-K/A filed with the SEC on March 12, 2015.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Use of Estimates

The preparation of unaudited consolidated financial statements in conformity with U.S. GAAP 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) collectability 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 approximately 14% of net revenue for the three and nine months ended September 30, 2015. Revenues from the Company’s distributors accounted for 30% and 28% of net revenue for the three and nine months ended September 30, 2014, 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 through 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 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 amount of these reductions is based on specific criteria included in the agreements and other factors known at the time. The Company accrues 100% of potential price protection adjustments at the time of sale and does not apply a breakage factor. The Company reverses the accrual for unclaimed price protection amounts as specific programs contractually end or when the Company believes unclaimed amounts are no longer subject to payment and will not be paid. See Note 6 for a summary of the Company's price protection activity.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

Business Combinations

The Company applies the provisions of ASC 805, Business Combinations, in the accounting for its acquisitions. It requires the Company to recognize separately from goodwill the assets acquired and the liabilities assumed, at the acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While the Company uses its best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date as well as contingent consideration, where applicable, its estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the consolidated statements of operations.

Costs to exit or restructure certain activities of an acquired company or the Company's internal operations are accounted for as termination and exit costs pursuant to ASC 420, Exit or Disposal Cost Obligations, and are accounted for separately from the business combination. A liability for costs associated with an exit or disposal activity is recognized and measured at its fair value in the consolidated statement of operations in the period in which the liability is incurred. When estimating the fair value of facility restructuring activities, assumptions are applied regarding estimated sub-lease payments to be received, which can differ materially from actual results. This may require the Company to revise its initial estimates which may materially affect the results of operations and financial position in the period the revision is made.

For a given acquisition, the Company may identify certain pre-acquisition contingencies as of the acquisition date and may extend its review and evaluation of these pre-acquisition contingencies throughout the measurement period in order to obtain sufficient information to assess whether the Company includes these contingencies as a part of the fair value estimates of assets acquired and liabilities assumed and, if so, to determine their estimated amounts.

If the Company cannot reasonably determine the fair value of a pre-acquisition contingency (non-income tax related) by the end of the measurement period, which is generally the case given the nature of such matters, the Company will recognize an asset or a liability for such pre-acquisition contingency if: (i) it is probable that an asset existed or a liability had been incurred at the acquisition date and (ii) the amount of the asset or liability can be reasonably estimated. Subsequent to the measurement period, changes in estimates of such contingencies will affect earnings and could have a material effect on results of operations and financial position.

In addition, uncertain tax positions and tax related valuation allowances assumed in connection with a business combination are initially estimated as of the acquisition date. The Company reevaluates these items quarterly based upon facts and circumstances that existed as of the acquisition date with any adjustments to the preliminary estimates being recorded to goodwill if identified within the measurement period. Subsequent to the measurement period or final determination of the tax allowance’s or contingency’s estimated value, whichever comes first, changes to these uncertain tax positions and tax related valuation allowances will affect the provision for income taxes in the consolidated statement of operations and could have a material impact on the results of operations and financial position.

Litigation and Settlement Costs

Legal costs are expensed as incurred. The Company is involved in disputes, litigation and other legal actions in the ordinary course of business. The Company continually evaluates uncertainties associated with litigation and records a charge equal to at least the minimum estimated liability for a loss contingency when both of the following conditions are met: (i) information available prior to issuance of the financial statements indicates that it is probable that an asset had been impaired or a liability had been incurred at the date of the financial statements and (ii) the loss or range of loss can be reasonably estimated.

Goodwill and Intangible Assets

Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the acquired net tangible and intangible assets. Intangible assets represent purchased intangible assets including developed technology and in-process research and development, or IPR&D, and technologies acquired or licensed from other companies. Purchased intangible assets with definitive lives are capitalized and amortized over their estimated useful lives. Technologies acquired or licensed from other companies are capitalized and amortized over the lesser of the terms of the agreement, or estimated useful life. The Company capitalizes IPR&D projects acquired as part of a business combination. On completion of each project, IPR&D assets are reclassified to developed technology and amortized over their estimated useful lives.

Impairment of Goodwill and Long-Lived Assets

Goodwill is the excess of the purchase price over the fair value of identifiable net assets acquired in business combinations accounted for under the purchase method. Goodwill is not amortized but is tested for impairment using a two-step method. Step one is the identification of potential impairment. This involves comparing the fair value of each reporting unit, which the Company has determined to be the entity itself, with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds the carrying amount, the goodwill of the reporting unit is considered not impaired and the second step of the impairment test is unnecessary. If the carrying amount of a reporting unit exceeds its fair value, the second step of the impairment test is performed to measure the amount of impairment loss, if any. The Company tests by reporting unit, goodwill and other indefinite-lived intangible assets for impairment as of October 31 or more frequently if it believes indicators of impairment exist.

During development, IPR&D is not subject to amortization and is tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. The Company reviews indefinite-lived intangible assets for impairment as of October 31, the date of its annual goodwill impairment review or whenever events or changes in circumstances indicate the carrying value may not be recoverable. Recoverability of indefinite-lived intangible assets is measured by comparing the carrying amount of the asset to the future discounted cash flows that asset is expected to generate. Once an IPR&D project is complete, it becomes a definite lived intangible asset and is evaluated for impairment both immediately prior to its change in classification and thereafter in accordance with the Company's policy for long-lived assets.

The Company regularly reviews the carrying amount of its long-lived assets, as well as the useful lives, to determine whether indicators of impairment may exist which warrant adjustments to carrying values or estimated useful lives. An impairment loss would be recognized when the sum of the expected future undiscounted net cash flows is less than the carrying amount of the asset. Should impairment exist, the impairment loss would be measured based on the excess of the carrying amount of the asset over the asset’s fair value.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board, or FASB, issued new accounting guidance related to revenue recognition. This new standard will replace all current U.S. GAAP guidance on this topic and eliminate all industry-specific guidance. The new revenue recognition standard provides a unified model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. This guidance will be effective for the Company beginning in the first quarter of fiscal year 2018 and can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. The Company is evaluating the impact of adopting this new accounting standard on its financial statements.

In August 2014, the FASB issued new accounting guidance related to the disclosures around going concern. The new standard provides guidance around management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures. This guidance will be effective for the Company beginning in the first quarter of fiscal year 2017. Early adoption is permitted. The Company does not expect the adoption of this standard to significantly impact its 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.

3. Business Combination

Acquisition of Entropic Communications, Inc.

On April 30, 2015, the Company completed its acquisition of Entropic Communications, Inc. ("Entropic"). Pursuant to the terms of the merger agreement dated as of February 3, 2015, by and among the Company, Entropic, and two wholly-owned subsidiaries of the Company ("the Merger Agreement"), all of the Entropic outstanding shares were converted into the right to receive consideration consisting of cash and shares of the Company’s Class A common stock. The Company paid an aggregate of $111.1 million and issued an aggregate of 20.4 million shares of the Company’s Class A common stock, to the stockholders of Entropic. In addition, the Company assumed all outstanding Entropic stock options and unvested restricted stock units that were held by continuing service providers (as defined in the Merger Agreement). The Company used Entropic’s cash and cash equivalents to fund a significant portion of the cash portion of the merger consideration and, to a lesser extent, its own cash and cash equivalents.

As a result of the acquisition, the Company expects to benefit from the economies of scale across engineering and supply chain operations, as well as from elimination of redundancy across engineering, sales, and general and administrative functions. Entropic has been recognized for pioneering the MoCA® (Multimedia over Coax Alliance) home networking standard and inventing Direct Broadcast Satellite outdoor unit (“DBS ODU”) solutions which consist of band translation switch ("BTS") and channel stacking switch ("CSS") products which simplify the installation required to support simultaneous reception of multiple channels from multiple satellites over a single cable. Entropic has a rich history of innovation and deep expertise in RF, analog/mixed signal and digital signal processing technologies. Entropic’s silicon solutions have been broadly deployed across major cable, satellite, and fiber service providers. The Company expects the acquisition of Entropic to add significant scale to the Company's analog/mixed-signal business, expand the Company’s addressable market and enhance the strategic value of the Company’s offerings to broadband and access partners, OEM customers, and service providers.

The merger has been accounted for under the acquisition method of accounting in accordance with ASC 805, Business Combinations, with MaxLinear treated as the accounting acquirer. Under this method of accounting, the Company recorded the acquisition based on the fair value of the consideration given and the cash consideration paid. The Company allocated the acquisition consideration paid to the identifiable assets acquired and liabilities assumed based on their respective preliminary fair values at the date of completion of the merger. Any excess of the value of consideration paid over the aggregate fair value of those net assets has been recorded as goodwill.

The total consideration for the Entropic acquisition of $289.4 million is comprised of the equity value of shares of the Company's common stock that were issued in the transaction of $173.8 million, the portion of outstanding equity awards deemed to have been earned as of April 30, 2015 of $4.5 million and cash of $111.1 million. The portion of outstanding equity awards deemed not to have been earned of $9.3 million as of April 30, 2015 will be expensed over the remaining future vesting period, including $0.8 million and $3.2 million for the three months and nine months ended September 30, 2015. Assumed equity awards consisted of 1.9 million of the Company's stock options and 1.3 million restricted stock units.

The Company capitalized $0.7 million of costs related to the registration and issuance of the 20.4 million shares of the Company’s Class A common stock to Entropic’s stockholders upon completion of the merger. In addition, the Company registered an additional 3.2 million shares related to shares of the Company’s Class A common stock which may be issued pursuant to outstanding equity awards under the former Entropic Stock Plans.

The estimated fair value of the purchase price consideration consisted of the following:

Cash	$	111,125
Class A common stock issued	173,781
Equity awards assumed	4,485
Total purchase consideration	$	289,391

Pursuant to the Company's business combinations accounting policy, the Company estimated the preliminary fair values of net tangible and intangible assets acquired and the excess of the consideration transferred over the aggregate of such fair values was recorded as goodwill. The preliminary fair values of net tangible assets and intangible assets acquired were based upon preliminary valuations and the Company's estimates and assumptions are subject to change within the measurement period (up to one year from the acquisition date). The primary areas that remain preliminary relate to the fair values of liabilities acquired, certain legal matters, income and non-income based taxes and residual goodwill. The Company expects to continue to obtain information to assist in determining the fair values of the net assets acquired during the measurement period.

In connection with the acquisition of Entropic, the Company has assumed liabilities related to Entropic product quality issues, warranty claims and contract obligations which are included in accrued expenses and other current liabilities in the purchase price allocation above.

The fair value of inventories acquired included an acquisition accounting fair market value step-up of $14.2 million, which was fully amortized as of September 30, 2015. During the three and nine months ended September 30, 2015, the Company recognized $0.9 million and $14.2 million, respectively, as a component of cost of sales as the inventory acquired on April 30, 2015 was sold to the Company’s customers.

During the three months ended September 30, 2015, the Company recorded a net $0.5 million adjustment to goodwill primarily due to a $0.4 million increase related to product settlements, $0.3 million increase related to foreign taxes payables and a return to provision true-up, offset by $0.2 million decrease related to valuation allowance adjustment to deferred tax liability.

The Company is subject to legal and regulatory requirements, including but not limited to those related to taxation in each of the jurisdictions in the countries in which it operates. The Company has conducted a preliminary assessment of liabilities arising from these tax matters in each of these jurisdictions, and has recognized provisional amounts in its initial accounting for the acquisition of Entropic for the identified liabilities. However, the Company is continuing its procedures to identify information pertaining to these matters as well as other legal and regulatory matters during the measurement period. The Company has not obtained all necessary information to finalize its provisional amounts pertaining to income taxes and loss contingencies associated with legal and regulatory matters.  If new information is obtained about facts and circumstances that existed at the acquisition date, the Company will either adjust its measurement of provisional amounts or recognize and measure liabilities not previously identified. 

Acquisition and integration-related costs of $5.3 million were included in selling, general, and administrative expenses in the Company's statement of operations for the nine months ended September 30, 2015.

The following table presents details of the preliminary identified intangible assets acquired through the acquisition of Entropic:

	Estimated Useful Life (in years)	Fair Value
Developed technology	7.0	$	43,600
In-process research and development	n/a	18,200
Trademarks and trade names	7.0	1,700
Customer relationships	5.0	4,700
Backlog	0.7	24,200
Total intangible assets		$	92,400

The fair value of the $92.4 million of identified intangible assets acquired in connection with the Entropic acquisition was estimated using an income approach. Under the income approach, an intangible asset's fair value is equal to the present value of future economic benefits to be derived from ownership of the asset. Indications of value are developed by discounting future net cash flows to their present value at market-based rates of return. More specifically, the fair value of the developed technology, IPR&D and backlog assets was determined using the multi-period excess earnings method, or MPEEM. MPEEM is an income approach to fair value measurement attributable to a specific intangible asset being valued from the asset grouping’s overall cash-flow stream. MPEEM isolates the expected future discounted cash-flow stream to its net present value. Significant factors considered in the calculation of the developed technology and IPR&D intangible assets were the risks inherent in the development process, including the likelihood of achieving technological success and market acceptance. Each project was analyzed to determine the unique technological innovations, the existence and reliance on core technology, the existence of any alternative future use or current technological feasibility and the complexity, cost, and time to complete the remaining development. Future cash flows for each project were estimated based on forecasted revenue and costs, taking into account the expected product life cycles, market penetration, and growth rates. Developed technology will begin amortization immediately and IPR&D will begin amortization upon the completion of each project. If any of the projects are abandoned, the Company will be required to impair the related IPR&D asset.

In connection with the Company’s acquisition of Entropic and to address issues primarily relating to the integration of the Company and Entropic businesses, the Company entered into a restructuring plan. See Note 4.

Acquisition of Physpeed, Co., Ltd.

On October 31, 2014, the Company acquired 100% of the outstanding common shares of Physpeed Co., Ltd. (“Physpeed”), a privately held developer of high-speed physical layer interconnect products addressing enterprise and telecommunications infrastructure market applications. The Company paid $9.3 million in cash in exchange for all outstanding shares of capital stock and equity of Physpeed. $1.1 million of the consideration payable to the former shareholders of Physpeed was placed into escrow pursuant to the terms of the definitive merger agreement. The escrow release date is twelve months following the closing date of October 31, 2014 and expected to be paid out after October 31,2015. In addition, the definitive merger agreement provided for potential consideration of $1.7 million of held back merger proceeds for the former principal shareholders of Physpeed which will be paid over a two year period contingent upon continued employment and potential earn-out consideration of up to $0.75 million to the former shareholders of Physpeed for the achievement of certain 2015 and 2016 revenue milestones. As of September 30, 2015, $0.8 million of held back merger proceeds have been paid. The Company had also entered into retention and performance-based agreements with Physpeed employees for up to $3.25 million to be paid in cash or shares of MaxLinear Class A common stock based on the achievement of certain 2015 and 2016 revenue milestones.

As a result of the acquisition, the Company expects to reduce costs through economies of scale. The acquisition of Physpeed significantly accelerates the Company's total addressable market expansion efforts into infrastructure for data center, as well as metro and long-haul telecommunications operators. Physpeed’s expertise in high-speed analog design, combined with the Company's proven low-power digital CMOS mixed signal-integration and DSP capabilities, is expected to bring to market solutions that will uniquely enable the data traffic growth generated from smartphones and tablets, and over-the-top, or OTT, streaming video, in addition to cloud computing and data analytics in hyper-scale data centers. The goodwill of $1.2 million arising from the acquisition consists largely of the synergies and economies of scale expected from combining the operations of the Company and Physpeed. None of the goodwill recognized is expected to be deductible for income tax purposes.

In accordance with accounting principles generally accepted in the United States, the Company accounted for the merger using the acquisition method of accounting for business combinations. Under this method of accounting, the Company recorded the acquisition based on the fair value of the consideration given and the cash consideration paid in the merger at the time of the merger. The Company allocated the purchase price to the identifiable assets acquired and liabilities assumed based on their respective fair values at the date of the completion of the merger. Any excess of the value of consideration paid over the aggregate fair value of those net assets has been recorded as goodwill.

	$	9,515

Acquisition-related costs of $0.3 million were included in selling, general, and administrative expenses in the Company's statement of operations for the year ended December 31, 2014.

The fair value of the acquired identifiable intangible assets of $10.0 million consists of developed technology of $2.7 million and IPR&D of $7.3 million. Both the developed technology and IPR&D are related to optical interconnect interface physical layers products and the estimated useful lives have been assessed to be seven years for the developed technology. Developed technology will be amortized immediately and IPR&D will begin amortization upon the completion of each project. If any of the projects are abandoned, the Company will be required to impair the related IPR&D asset. The fair value of the developed technology and IPR&D was determined using the multi-period excess earnings method, or MPEEM. MPEEM is an income approach to fair value measurement attributable to a specific intangible asset being valued from the asset grouping’s overall cash-flow stream. MPEEM isolates the expected future discounted cash-flow stream to their net present value. Significant factors considered in the calculation were the risks inherent in the development process, including the likelihood of achieving technological success and market acceptance. Each project was analyzed to determine the unique technological innovations, the existence and reliance on core technology, the existence of any alternative future use or current technological feasibility and the complexity, cost, and time to complete the remaining development. Future cash flows for each project were estimated based on forecasted revenue and costs, taking into account the expected product life cycles, market penetration, and growth rates.

Compensation Arrangements

In connection with the acquisition of Physpeed, the Company has agreed to pay additional consideration in future periods. There was a holdback of the merger proceeds whereby the former principal shareholders of Physpeed will be paid a quarterly amount of $0.2 million beginning on January 31, 2015 and ending on October 31, 2016 for a total of $1.7 million. Certain employees of Physpeed will be paid a total of $0.1 million of which $0.07 million will be paid in 2015 and $0.05 million will be paid in 2016. These payments are accounted for as transactions separate from the business combination as the payments are contingent upon continued employment and will be recorded as post-combination compensation expense in the Company's financial statements during the service period. The Company also agreed to a working capital adjustment of $0.04 million that was settled by December 31, 2014.

Earn-Out

The contingent earn-out consideration had an estimated fair value of $0.3 million at the date of acquisition. The earn-out is payable up to $0.75 million to the former shareholders of Physpeed. The 2015 earn-out is based on $0.375 million multiplied by the 2015 revenue percentage as defined in the definitive merger agreement. The 2016 earn-out is based on $0.375 million multiplied by the 2016 revenue percentage as defined in the definitive merger agreement. Subsequent changes to the fair value will be recorded through earnings. The fair value of the earn-out was $0.1 million and $0.3 million at September 30, 2015 and December 31, 2014, respectively. The change in the fair value of the earn-out was primarily due to revisions to the Company's expectations of earn-out achievement.

RSU Awards

The Company will grant restricted stock units, or RSUs, under its equity incentive plan to Physpeed continuing employees if certain 2015 and 2016 revenue targets are met contingent upon continued employment. The total maximum amounts of these RSUs are $3.25 million. These participants will be eligible to receive $1.625 million of the RSUs in 2015 and $1.625 million in 2016.

The 2015 performance grant, if any earned, will be based on the calculation of the 2015 maximum revenue RSU amount multiplied by the 2015 revenue percentage as defined in the definitive merger agreement. The 2015 maximum revenue RSU amount is 50% of the aggregate maximum RSU award value divided by the 2015 average company share price (the average closing sales prices of stock trading on the New York Stock exchange over five consecutive trading days ending on the trade date that is the third trading date prior to the 2015 determination date (no later than ten business days after filing the Form 10-K for the 2015 fiscal year)). Qualifying revenues are the net revenues recognized in the 2015 fiscal year directly attributable to sales of Physpeed products or the Company’s provision of non-recurring engineering services exclusively with respect to the Physpeed products in accordance with U.S. GAAP reflected in the Company’s audited financial statements.

The 2016 performance grant, if any earned, will be based on the calculation of the 2016 maximum revenue RSU amount multiplied by the 2016 revenue percentage as defined in the definitive merger agreement. The 2016 maximum revenue RSU amount is 50% of the aggregate maximum RSU award value divided by the 2016 average company share price (the average closing sales prices of stock trading on the New York Stock exchange over five consecutive trading days ending on the trade date that is the third trading date prior to the 2016 determination date (no later than ten business days after filing the Form 10-K for the 2016 fiscal year). Qualifying revenues are the net revenues recognized in the 2016 fiscal year directly attributable to sales of Physpeed products or the Company’s provision of non-recurring engineering services exclusively with respect to the Physpeed products in accordance with U.S. GAAP reflected in the Company’s audited financial statements.

The Company will record compensation expense for the 2015 RSUs over a 14 month service period from October 31, 2014 through December 31, 2015. The Company will record compensation expense for the 2016 RSUs over a 26 month service period from October 31, 2014 through December 31, 2016. The Company has recorded an accrual for the stock-based compensation expense for the 2015 and 2016 RSUs of $0.7 million at September 30, 2015.

4. Restructuring Activity

In connection with the Company's acquisition of Entropic, the Company entered into a restructuring plan to address matters primarily relating to the integration of the Company and Entropic businesses. In connection with this plan, the Company terminated the employment of 73 Entropic employees during the nine months endedSeptember 30, 2015. The Company recognized associated non-recurring employee separation charges of approximately $5.7 million in the nine months endedSeptember 30, 2015 related to these terminations. Included in these employee separation charges is $1.5 million of stock compensation for accelerated stock options and RSUs vesting due to double trigger change of control agreements and other special agreements in effect with certain Entropic employees.

Additionally, in connection with the restructuring plan, the Company ceased use of the majority of Entropic's former headquarters. Accordingly, the Company recognized lease impairment charges of $1.1 million based on the adjustment to the net present value of the remaining lease obligation on the cease use date. The Company also recorded impairment charges of $3.7 million related to leasehold improvements on the unused premises.

The following table presents the activity related to the plan, which is included in restructuring charges in the unaudited consolidated statements of operations:

Liabilities
Contingent Consideration	$	265
Total	$	265

As of September 30, 2015, the Company held 7 government and corporate debt securities with an aggregate fair value of $11.1 million that were in an unrealized loss position for less than 12 months. The gross unrealized losses of $0.006 million at September 30, 2015 represent temporary impairments on government and corporate debt securities related to multiple issuers, and were primarily caused by fluctuations in U.S. interest rates. 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; including changes in the financial condition of the security’s underlying collateral; any downgrades of the security by a rating agency; nonpayment of scheduled interest, or the reduction or elimination of dividends; as well as 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 1 and 2 years as of September 30, 2015.

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 on the basis of valuations using quoted market prices or alternate pricing sources and models utilizing market observable inputs, respectively. The Company’s money market funds were valued based on quoted prices for the specific securities in an active market and were therefore classified as Level 1. The government and corporate debt securities have been valued on the basis of valuations provided by third-party pricing services, as derived from such services’ pricing models. The pricing services may use a consensus price which is a weighted average price based on multiple sources or mathematical calculations to determine the valuation for a security, and have been classified as Level 2. The Company reviews Level 2 inputs and fair value for reasonableness and the values may be further validated by comparison to independent pricing sources. In addition, the Company reviews third-party pricing provider models, key inputs and assumptions and understands the pricing processes at its third-party providers in determining the overall reasonableness of the fair value of its Level 2 financial instruments. As of September 30, 2015 and December 31, 2014, the Company has not made any adjustments to the prices obtained from its third party pricing providers. The contingent liability is classified as Level 3 as of September 30, 2015 and December 31, 2014 and is valued using an internal rate of return model. The assumptions used in preparing the internal rate of return model include estimates for future revenues related to Physpeed products and services and a discount factor of 0.77% to 0.38% and 0.54% to 0.33% at September 30, 2015 and December 31, 2014, respectively. The assumptions used in preparing the internal rate of return model include estimates for outcome if milestone goals are achieved, the probability of achieving each outcome and discount rates. Significant changes in any of the unobservable inputs used in the fair value measurement of contingent consideration in isolation could result in a significantly lower or higher fair value. A change in estimated future revenues would be accompanied by a directionally similar change in fair value.

7. 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 endedSeptember 30, 2015 was $10.14. The weighted-average grant date fair value per share of the RSUs and RSAs granted in the nine months endedSeptember 30, 2014 was $9.04. No stock options were granted during the nine months ended September 30, 2015.

The fair values of stock options and employee stock purchase rights (related to the Company's ESPP) were estimated at their respective grant date using the following assumptions:

Stock Options

	Nine Months Ended September 30,
	2014
Weighted-average grant date fair value per share	$	4.03
Risk-free interest rate	1.70		%
Dividend yield	—		%
Expected life (years)	4.56
Volatility	51.00		%

Employee Stock Purchase Rights

	Nine Months Ended September 30,
	2015			2014
Weighted-average grant date fair value per share	$	2.25		$	2.47
Risk-free interest rate	0.09		%	0.05		%
Dividend yield	—		%	—		%
Expected life (years)	0.50			0.50
Volatility	32.65		%	47.75		%

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 historical data due to the Company’s limited number of stock option exercises under the 2010 Equity Incentive Plan. 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. Effective for the nine months ended September 30, 2014, the Company is no longer incorporating the historical volatility of comparable companies in determining estimated volatility.

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

	Three Months Ended September 30,				Nine Months Ended September 30,
	2015		2014		2015		2014
Cost of net revenue	$	73	$	35	$	169	$	96
Research and development	3,496		2,574		8,889		7,152

MAXLINEAR, INC.

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

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

In connection with the acquisition of Entropic, the Company assumed stock options and RSUs originally granted by Entropic. Stock-based compensation expense in the three and nine months ended September 30, 2015 included $0.8 million and $3.2 million, respectively, related to assumed Entropic stock options and RSUs.

In the nine months ended September 30, 2015, the Company granted 1.1 million RSUs with a fair value of $11.2 million related to its annual equity compensation review program, which will be expensed over the next four years. In the nine months ended September 30, 2014, the Company granted 0.7 million RSUs with a fair value of $6.4 million and 0.4 million stock options with a fair value of $1.7 million related to its annual equity compensation review program, which are expensed over the next four years.

Employee Benefit Plans

At September 30, 2015, the Company had stock-based compensation awards outstanding under the following plans: the 2004 Stock Plan, the 2010 Equity Incentive Plan and the 2010 Employee Stock Purchase Plan as well as the following former Entropic plans: the RF Magic 2000 Incentive Stock Plan, the 2001 Stock Option Plan, the 2007 Equity Incentive Plan, the 2007 Non-Employee Director's Plan and the 2012 Inducement Award Plan. All current stock awards are issued under the 2010 Equity Incentive Plan and 2010 Employee Stock Purchase Plan.

2010 Equity Incentive Plan

The 2010 Equity Incentive 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, 2015, 1.5 million shares of Class A common stock were automatically added to the shares authorized for issuance under the 2010 Equity Incentive Plan pursuant to an “evergreen” provision contained in the 2010 Equity Incentive 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 Class A 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, 2015, 0.5 million 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.

Executive Incentive Bonus Plan

In April 2012, the Company's compensation committee amended its Executive Incentive Bonus Plan to, among other things, permit the settlement of awards under the plan in the form of shares of its Class A common stock. In May 2013, the Company's compensation committee amended its Executive Incentive Bonus Plan to permit the settlement of awards under the plan in any combination of cash or shares of its Class A common stock. For the January 1, 2015 to June 30, 2015, 2014 and 2013 performance period, actual awards under the Executive Incentive Bonus Plan were settled in Class A common stock issued under its 2010 Equity Incentive Plan with the number of shares issuable to plan participants determined based on the closing sales price of the Company's Class A common stock as determined in trading on the New York Stock Exchange on August 20, 2015, May 14, 2015 and May 9, 2014, respectively. Additionally, the Company settled all bonus awards for all other employees for the January 1, 2015 to June 30, 2015, 2014 and 2013 performance period in shares of its Class A common stock. The Company issued 0.3 million shares of its Class A common stock for the January 1, 2015 to June 30, 2015 performance period upon settlement of the bonus awards on August 20, 2015. The Company issued 0.2 million shares of its Class A common stock for the 2014 performance period upon settlement of the bonus awards on May 14, 2015. The Company issued 0.6 million shares of its Class A common stock for the 2013 performance period upon settlement of the bonus awards on May 9, 2014.

Common Stock

At September 30, 2015, 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.

8. 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. The income tax provision consists primarily of income taxes related to the Company's operations in foreign jurisdictions as well as accruals for tax contingencies. 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.

As the Company does not believe that it is more-likely-than-not that it will realize a benefit from its U.S. net deferred tax assets, including its U.S. net operating losses, the Company continues to provide a full valuation allowance against those assets and therefore does not incur significant U.S. income tax expense or benefit. Additionally, the Company completed the acquisition of Entropic Communications in the second quarter of 2015. As a result of the acquisition, there was a valuation allowance release that resulted in a tax benefit of $1.6 million due to the purchase accounting adjustment for the net deferred tax liability. Furthermore, the Company does not incur expense or benefit in the certain tax free jurisdictions in which it operates.

The Company recorded a provision for income taxes of $0.5 million and a benefit of $0.6 million for the three and nine months ended September 30, 2015, respectively. The Company recorded a provision for income taxes of $0.03 million and $0.5 million for the three and nine months ended September 30, 2014, respectively. The provision (benefit) for income taxes for the three and nine months ended September 30, 2015 and 2014 primarily relates to income taxes in certain foreign jurisdictions.

During the nine months ended September 30, 2015, the Company’s unrecognized tax benefits increased by $1.9 million which includes an amount of $1.5 million related to the acquisition of Entropic. The Company does not anticipate its unrecognized tax benefits will change significantly over the next 12 months. Accrued interest and penalties associated with uncertain tax positions as of September 30, 2015 were $0.05 million and $0.02 million, respectively.

The Federal examination by the Internal Revenue Service for the years 2010 and 2011 was completed during the three months ended March 31, 2014. Any impact from the audit was included in the 2013 financial statements. The Company is not currently under examination in any other jurisdictions.

Beginning on February 9, 2015, eleven stockholder class action complaints (captioned Langholz v. Entropic Communications, Inc., et al., C.A. No. 10631-VCP (filed Feb. 9, 2015); Tomblin v. Entropic Communications, Inc., C.A. No. 10632-VCP (filed Feb. 9, 2015); Crill v. Entropic Communications, Inc., et al., C.A. No. 10640-VCP (filed Feb. 11, 2015); Wohl v.

The complaints name Entropic, the board of directors of Entropic, MaxLinear, Excalibur Acquisition Corporation, and Excalibur Subsidiary, LLC as defendants. The complaints generally allege that, in connection with the proposed acquisition of Entropic by MaxLinear, the individual defendants breached their fiduciary duties to Entropic stockholders by, among other things, purportedly failing to take steps to maximize the value of Entropic to its stockholders and agreeing to allegedly preclusive deal protection devices in the merger agreement. The

26

NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS

complaints further allege that Entropic, MaxLinear, and/or the merger subsidiaries aided and abetted the individual defendants in the alleged breaches of their fiduciary duties. The complaints seek, among other things, an order enjoining the defendants from consummating the proposed transaction, an order declaring the merger agreement unlawful and unenforceable, in the event that the proposed transaction is consummated, an order rescinding it and setting it aside or awarding rescissory damages to the class, imposition of a constructive trust, damages, and/or attorneys’ fees and costs.

On March 27, 2015, plaintiffs Ankur Saggar, Jon Werbowsky, and Angelo Agosti filed an amended class action complaint. Also on March 27, 2015, plaintiffs Martin Wohl and Jeffrey Park filed an amended class action complaint. On April 1, 2015, plaintiff Mark Respler filed an amended class action complaint.

On April 16, 2015, the Court entered an order consolidating the Delaware actions, captioned In re Entropic Communications, Inc. Consolidated Stockholders Litigation, C.A. No. 10631-VCP (the “Consolidated Action”). The April 16, 2015 order appointed plaintiffs Rama Iyer and Jon Werbowsky as Co-Lead Plaintiffs and designated the amended complaint filed by plaintiffs Ankur Saggar, Jon Werbowsky, and Angelo Agosti as the operative complaint (the “Amended Complaint”).

The Amended Complaint names as defendants Entropic, the board of directors of Entropic, the Company, Excalibur Acquisition Corporation, and Excalibur Subsidiary, LLC. The Amended Complaint generally alleges that, in connection with the proposed acquisition of Entropic by the Company, the individual defendants breached their fiduciary duties to Entropic stockholders by, among other things, purportedly failing to maximize the value of Entropic to its stockholders, engaging in a purportedly unfair and conflicted sale process, agreeing to allegedly preclusive deal protection devices in the merger agreement, and allegedly misrepresenting and/or failing to disclose all material information in connection with the proposed transaction. The Amended Complaint further alleges that the Company and the merger subsidiaries aided and abetted the individual defendants in the alleged breaches of their fiduciary duties. The Amended Complaint seeks, among other things: an order declaring the merger agreement unlawful and unenforceable, an order rescinding, to the extent already implemented, the merger agreement, an order enjoining defendants from consummating the proposed transaction, imposition of a constructive trust, and attorneys’ and experts’ fees and costs.

On April 24, 2015, the parties to the Consolidated Action entered into a memorandum of understanding regarding a proposed settlement of the Delaware actions. The proposed settlement is subject to negotiation of the settlement papers by the parties and is subject to court approval after notice and an opportunity to object is provided to the proposed settlement class. There can be no assurance that the parties will reach agreement regarding the final terms of the settlement agreement or that the Court of Chancery will approve the settlement.

Based on the above, the Company has not recorded an accrual for loss contingencies associated with the Delaware actions; determined that an unfavorable outcome is probable or reasonably possible; or determined that the amount or range of any possible loss is reasonably estimable.

CrestaTech Litigation

On January 21, 2014, CrestaTech Technology Corporation, or CrestaTech, filed a complaint for patent infringement against us in the United States District Court of Delaware (the “District Court Litigation”). In its complaint, CrestaTech alleges that we infringe U.S. Patent Nos. 7,075,585 (the “’585 Patent”) and 7,265,792. In addition to asking for compensatory damages, CrestaTech alleges willful infringement and seeks a permanent injunction. CrestaTech also names Sharp Corporation, Sharp Electronics Corp. and VIZIO, Inc. as defendants based upon their alleged use of our television tuners. On January 28, 2014, CrestaTech filed a complaint with the U.S. International Trade Commission, or ITC, again naming us, Sharp, Sharp Electronics, and VIZIO (“the “ITC Investigation”). On May 16, 2014 the ITC granted CrestaTech’s motion to file an amended complaint adding six OEM Respondents, namely, SIO International, Inc., Hon Hai Precision Industry Co., Ltd., Wistron Corp., Wistron Infocomm Technology (America) Corp., Top Victory Investments Ltd. and TPV International (USA), Inc. (collectively, with us, Sharp and VIZIO, the “Company Respondents”). CrestaTech’s ITC complaint alleges a violation of 19 U.S.C. § 1337 through the importation into the United States, the sale for importation, or the sale within the United States after importation of the Company’s accused products that CrestaTech alleges infringe the same two patents asserted in the Delaware action. Through its ITC complaint, CrestaTech seeks an exclusion order preventing entry into the United States of certain of our television tuners and televisions containing such tuners from Sharp, Sharp Electronics, and VIZIO. CrestaTech also seeks a cease and desist order prohibiting the Company Respondents from engaging in the importation into, sale for importation into, the sale after importation of, or otherwise transferring within the United States certain of the Company's television tuners or televisions containing such tuners.

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

On December 1-5, 2014, the ITC held a trial in the ITC Investigation. On February 27, 2015, the Administrative Law Judge issued a written Initial Determination (“ID”), ruling that the Company Respondents do not violate Section 1337 in connection with CrestaTech’s asserted patents because CrestaTech failed to satisfy the economic prong of the domestic industry requirement pursuant to Section 1337(a)(2). In addition, the ID stated that certain of the our television tuners and televisions incorporating those tuners manufactured and sold by certain customers infringe three claims of the ‘585 Patent, and these three claims were not determined to be invalid. On April 30, 2015, the ITC issued a notice indicating that it intended to review portions of the ID finding no violation of Section 1337, including the ID’s findings of infringement with respect to, and validity of, the ‘585 Patent, and the ID’s finding that CrestaTech failed to establish the existence of a domestic industry within the meaning of Section 1337.

The Commission requested additional briefing from the parties on certain issues under review by the Commission. The ITC has now issued its opinion, which terminates its investigation. The opinion affirmed the findings of the administrative law judge that no violation of Section 1337 had occurred because CrestaTech had failed to establish the economic prong of the domestic industry requirement. The ITC also affirmed the administrative law judge's finding of infringement with respect to the three claims of the '585 Patent that were not held to be invalid. CrestaTech may now appeal the decision of the ITC to the United States Court of Appeals for the Federal Circuit. The District Court Litigation remains stayed pending resolution of any appeal to the ITC. In addition, we have filed four petitions for inter partes review ("IPR") by the US Patent Office of the two CrestaTech patents asserted against us. We cannot predict the outcome of any appeal by CrestaTech, the District Court Litigation, or the IPRs.

In addition, we have filed four petitions for inter partes review (“IPR”) by the U.S. Patent Office of the two CrestaTech patents asserted against us. The Patent Trial and Appeal Board did not institute two of these IPRs as being redundant to IPRs filed by another party that are already underway for the same CrestaTech patent.  The remaining two petitions were instituted or instituted-in-part and, together with the IPRs filed by third parties, there are currently six pending IPR proceedings involving the two CrestaTech patents asserted against us.  The two specific claims mentioned above are included in at least one of the review proceedings instituted and currently pending against CrestaTech. 

In view of the final determination of no violation in the ITC Investigation and the institution of IPR proceedings, the Company has not recorded an accrual for loss contingencies associated with the 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.

Overview

We are a provider of integrated, radio-frequency and mixed-signal integrated circuits for broadband communications and data center, metro, and long-haul transport network 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 (SoCs), which incorporate our highly integrated radio system architecture and the functionality necessary to receive and demodulate broadband signals, and physical medium devices that provide a constant current source, current-to-voltage regulation, and data alignment and retiming functionality in optical interconnect applications. Through our acquisition of Entropic Communications, Inc., or Entropic, in April of 2015, we provide semiconductor solutions for the connected home, ranging from MoCA® (Multimedia over Coax Alliance) solutions that transform how traditional HDTV broadcast and Internet Protocol- (IP) based streaming video content is seamlessly, reliably, and securely delivered, processed, and distributed into and throughout the home, to digital set top box (STB) components and system solutions for the global satellite, terrestrial, cable and IP television (IPTV) markets. Our products enable the distribution and display of broadband video and data content in a wide range of electronic devices, including Pay-TV operator set top boxes and voice and data gateways, hybrid analog and digital televisions, Direct Broadcast Satellite outdoor units, and optical modules for data center, metro, and long-haul transport network applications.

Our net revenue has grown from approximately $0.6 million in fiscal 2006 to $133.1 million in fiscal 2014. In the nine months ended September 30, 2015 and 2014, respectively, our net revenue was derived primarily from sales of RF receivers and RF receiver systems-on-chip, and MoCA connectivity solutions into operator voice and data modems and gateways and global analog and digital RF receiver products for analog and digital television applications. These analog and digital television applications include Direct Broadcast Satellite outdoor unit (DBS ODU) solutions which consist of our and translation switch (BTS) and channel stacking switch (CSS) products which simplify the installation required to support simultaneous reception of multiple channels from multiple satellites over a single cable. 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, data modems, and gateways for the broadband service provider and Pay-TV industries, manufacturers selling into the Cable infrastructure market, and manufacturers of optical module and telecommunications equipment.

Products shipped to Asia accounted for 90% of net revenue in the three and nine months ended September 30, 2015, respectively, and 90% and 94% of net revenue in the three and nine months ended September 30, 2014, respectively. A significant but declining portion of these sales in Asia is through distributors. Although a large percentage of our products is shipped to 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 nine months ended September 30, 2015 and 2014 related principally to sales to Asian set top box manufacturers delivering products into Europe, Middle East, and Africa, or EMEA markets. Similarly, revenue generated from sales of our cable modem products during the nine months ended September 30, 2015 and 2014 related principally to sales to Asian ODMs and contract manufacturers delivering products into European and North American markets. To date, most of our sales have been denominated in United States dollars.

29

A significant portion of our net revenue has historically been generated by a limited number of customers. In the three months ended September 30, 2015, two of our customers accounted for 41% of our net revenue, and our ten largest customers collectively accounted for 77% of our net revenue. In the nine months ended September 30, 2015, two of our customers accounted for 42% of our net revenue, and our ten largest customers collectively accounted for 76% of our net revenue. In the three months ended September 30, 2014, one of our customers accounted for 25% of our net revenue, and our ten largest customers collectively accounted for 67% of our net revenue. In the nine months ended September 30, 2014, one of our customers accounted for 31% of our net revenue, and our ten largest customers collectively accounted for 69% of our net revenue. For certain customers, we sell multiple products into disparate end user applications such as cable modems and cable set-top boxes.

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 hybrid television market, a design-in can have a product life cycle of 9 to 18 months. In the terrestrial retail digital set top box market, a design-in can have a product life cycle of 18 to 24 months. In the cable operator modem and gateway sectors, a design-in can have a product life cycle of 24 to 48 months. In the satellite operator gateway and DBS ODU sectors, a design-in can have a product life cycle of 24 months to 60 months and beyond.

Critical Accounting Policies and Estimates

Management’s discussion and analysis of our financial condition and results of operations is 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, business combinations, allowance for doubtful accounts, inventory valuation, production masks, income taxes, stock-based compensation, goodwill and intangible assets and impairment of goodwill and long-lived assets. 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.

Business Combinations

The Company applies the provisions of ASC 805, Business Combinations, in the accounting for its acquisitions. It requires the Company to recognize separately from goodwill the assets acquired and the liabilities assumed, at the acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While the Company uses its best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date as well as contingent consideration, where applicable, its estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the consolidated statements of operations.

Costs to exit or restructure certain activities of an acquired company or the Company's internal operations are accounted for as termination and exit costs pursuant to ASC 420, Exit or Disposal Cost Obligations, and are accounted for separately from the business combination. A liability for costs associated with an exit or disposal activity is recognized and measured at its fair value in the consolidated statement of operations in the period in which the liability is incurred. When estimating the fair value of facility restructuring activities, assumptions are applied regarding estimated sub-lease payments to be received, which can differ materially from actual results. This may require the Company to revise its initial estimates which may materially affect the results of operations and financial position in the period the revision is made.

30

For a given acquisition, the Company may identify certain pre-acquisition contingencies as of the acquisition date and may extend its review and evaluation of these pre-acquisition contingencies throughout the measurement period in order to obtain sufficient information to assess whether the Company includes these contingencies as a part of the fair value estimates of assets acquired and liabilities assumed and, if so, to determine their estimated amounts.

If the Company cannot reasonably determine the fair value of a pre-acquisition contingency (non-income tax related) by the end of the measurement period, which is generally the case given the nature of such matters, the Company will recognize an asset or a liability for such pre-acquisition contingency if: (i) it is probable that an asset existed or a liability had been incurred at the acquisition date and (ii) the amount of the asset or liability can be reasonably estimated. Subsequent to the measurement period, changes in estimates of such contingencies will affect earnings and could have a material effect on results of operations and financial position.

In addition, uncertain tax positions and tax related valuation allowances assumed in connection with a business combination are initially estimated as of the acquisition date. The Company reevaluates these items quarterly based upon facts and circumstances that existed as of the acquisition date with any adjustments to the preliminary estimates being recorded to goodwill if identified within the measurement period. Subsequent to the measurement period or final determination of the tax allowance’s or contingency’s estimated value, whichever comes first, changes to these uncertain tax positions and tax related valuation allowances will affect the provision for income taxes in the consolidated statement of operations and could have a material impact on the results of operations and financial position.

There were no significant changes, other than the addition of business combinations, during the nine months ended September 30, 2015 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, 2014 contained in the Annual Report on Form 10-K filed with the SEC on February 23, 2015, as amended by Amendment No. 1 on Form 10-K/A filed with the SEC on March 12, 2015.

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 integrated radio frequency analog and mixed signal semiconductor solutions for broadband communication applications. A significant but declining portion of our end customers purchases 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.

Restructuring Charges. Restructuring charges consist of employee severance and stock compensation expenses, and lease and leasehold impairment charges related to our restructuring plan entered into as a result of our acquisition of Entropic, and an adjustment related to restructuring plan implemented by Entropic prior to acquisition.

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

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

31

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.

The acquisition of Entropic Communications, Inc., or Entropic, in April of 2015 has changed the composition, breadth and diversity of MaxLinear’s technology portfolio. In particular, MoCA technologies have expanded MaxLinear’s platform in cable, satellite, and telecommunications applications, and analog channel stacking solutions have expanded MaxLinear’s presence in Direct Broadcast Satellite outdoor unit applications. In addition, the Company has increased its investment in new technology development targeting infrastructure markets, while reducing its investments into retail-oriented and legacy technologies such as terrestrial tuners, hybrid TV tuners, and legacy video processing technologies. As a result of these changes, MaxLinear has realigned its revenue composition with its strategic investment focus and platform presence. The Company has illustrated these changes with the market terms operator, infrastructure and other, and legacy video SoC.

32

Within the operator category, the primary contributors are MaxLinear’s broadband RF receivers, MoCA connectivity solutions, and analog and digital channel stacking satellite outdoor unit solutions. Within the infrastructure and other category, the primary revenue contributors are hybrid TV tuners and terrestrial set-top box TV tuners for DTA’s that are sold through retail channels, high-speed interconnect products for the data center, metro, and long haul markets, and access technologies for last mile high-speed data access and distribution solutions for multi-dwelling units. The legacy video SoC category includes video processing technologies used primarily in cable high definition digital-to-analog converters and other client IP devices; consistent with Entropic’s previously announced plans, MaxLinear intends to support existing product shipments in this market but does not plan to use its resources to expand the legacy SoC technology portfolio.

The increase in net revenue in the three months ended September 30, 2015, as compared to the three months ended September 30, 2014, was primarily due to $44.3 million of growth in operator applications, contributed primarily by analog channel-stacking ("aCSS") and MoCA products related to our Entropic acquisition, as well as organic growth across each of our other operator sub-categories except operator digital-to-analog converter applications, which declined modestly. Growth of $18.7 million in our legacy video SoC products was attributable to our acquisition of Entropic. Declines in infrastructure and other revenues of $0.4 million were primarily driven by hybrid-TV and consumer digital-to-analog terrestrial set-top box applications, which offset growth in retail MoCA products related to our Entropic acquisition and high-speed interconnect products related to our Physpeed acquisition.

The increase in net revenue in the nine months ended September 30, 2015, as compared to the nine months ended September 30, 2014, was primarily due to $73.3 million of growth in operator applications, contributed primarily by analog channel-stacking and MoCA products related to our Entropic acquisition, as well as organic growth across each of our other operator sub-categories. Growth of $31.2 million in our legacy video SoC products was attributable to our acquisition of Entropic. Declines in infrastructure and other revenue of $3.7 million were driven by hybrid-TV and consumer digital-to-analog terrestrial set-top box applications, partially offset by growth in retail MoCA and high-speed interconnect applications.

Cost of Net Revenue and Gross Profit

	2015			2014			% Change		2015			2014			% Change
	(dollars in thousands)								(dollars in thousands)
Cost of net revenue	$	44,141		$	12,632		249	%	$	101,748		$	38,426		165	%

% of net revenue	54		%	61		%			49		%	62		%

The decline in the gross profit percentage for the three months ended September 30, 2015, as compared to the three months ended September 30, 2014, was primarily due to amortization of intellectual property costs of $1.6 million and revaluation of inventory amortization of $0.9 million related to the Entropic acquisition. The gross margin decline was also driven by the significant increase in Entropic-related product revenue, which has historically generated lower gross margin than our previous corporate average.

The decline in the gross profit percentage for the nine months ended September 30, 2015, as compared to the nine months ended September 30, 2014, was primarily due to revaluation of inventory amortization of $14.2 million and amortization of intellectual property costs of $2.6 million related to the Entropic acquisition. To a lesser extent, the decline in gross margin was also driven by the increase in Entropic-related product revenue, which has historically generated lower gross margin than our previous corporate average.

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,
	2015			2014			% Change		2015			2014			% Change
	(dollars in thousands)								(dollars in thousands)

% of net revenue	25		%	46		%			31		%	42		%

33

The increase in research and development expense for the three months ended September 30, 2015, as compared to the three months ended September 30, 2014, was primarily due to an increase in headcount-related items (including stock-based compensation) of $6.2 million and the combined increases in design tools, travel, and occupancy expenses of $1.8 million.

The increase in research and development expense for the nine months ended September 30, 2015, as compared to the nine months ended September 30, 2014, was primarily due to an increase in headcount-related items (including stock-based compensation) of $12.2 million, combined increases in design tools, prototype, and occupancy expenses of $5.2 million, and severance expenses related to our exit of R&D related activities in Shanghai, China of $0.7 million.

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,
	2015			2014			% Change		2015			2014			% Change
	(dollars in thousands)								(dollars in thousands)
Selling, general and administrative	$	25,457		$	8,141		213	%	$	60,021		$	24,590		144	%
% of net revenue	27		%	25		%			30		%	24		%

The increase in selling, general and administrative expense in the three months ended September 30, 2015, as compared to the three months ended September 30, 2014, was primarily due to the amortization of purchased intangible assets of $12.1 million associated with our Entropic acquisition, an increase in headcount-related items (including stock-based compensation) of $1.7 million and an increase in outside services, professional fees and occupancy expenses of $2.1 million.

The increase in selling, general and administrative expense in the nine months ended September 30, 2015, as compared to the nine months ended September 30, 2014, was primarily due to transaction costs of $5.3 million and amortization of purchased intangible assets of $20.1 million associated with our Entropic acquisition, an increase in headcount-related items (including stock-based compensation) of $3.6 million and an increase in outside services, professional fees and occupancy expenses of $3.4 million.

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 and continue to build our international administrative infrastructure.

Restructuring charges

Restructuring charges in the three and nine months ended September 30, 2015 consist of employee severance and stock compensation expenses and lease and leasehold impairment charges related to our restructuring plan entered into as a result of our acquisition of Entropic. These charges were primarily incurred during the second quarter of 2015. During the three months ended September 30, 2015, the Company recorded $0.6 million expense related to a lease that was restructured before the completion of our acquisition of Entropic.

Interest and Other Income (Expense)

	Three Months Ended September 30,					Nine Months Ended September 30,

Interest income	$	47	$	61		$	168	$	182
Other income (expense), net	407		(49		)	351		(79		)

34

Interest income decreased in the three and nine months ended September 30, 2015 as compared to the three and nine months ended September 30, 2014 due to fluctuations in cash equivalent and investment balances and interest rates. Other income (expense), net increased in the three and nine months ended September 30, 2015 as compared to the three and nine months ended September 30, 2014 primarily due to gains on foreign currency transactions at the Entropic Asia subsidiaries.

Provision (Benefit) for Income Taxes

	Three Months Ended September 30,				Nine Months Ended September 30,
	2015		2014		2015			2014
	(dollars in thousands)				(dollars in thousands)
Provision (benefit) for income taxes	$	549	$	28	$	(631	)	$	456

The provision for income taxes for the three months ended September 30, 2015 was $0.5 million or approximately 25.8% of pre-tax income compared to a provision for income taxes of $0.03 million or approximately (0.9)% of pre-tax loss for the three months ended September 30, 2014. The benefit from income taxes for the nine months ended September 30, 2015 was $0.6 million or approximately 1.8% of pre-tax loss compared to a provision for income taxes of $0.5 million or approximately (10.8)% of pre-tax loss for the nine months ended September 30, 2014. 

The provision (benefit) for income taxes for the three and nine months endedSeptember 30, 2015 and 2014 primarily relate to income tax in foreign jurisdictions as well as accruals for tax contingencies. During the nine months endedSeptember 30, 2015, we recorded a net benefit from income taxes due to the offset by the valuation allowance release resulting from the net deferred tax liability acquired in the Entropic acquisition. 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. Additionally, the Company completed the acquisition of Entropic in the second quarter of 2015. As a result of the acquisition, there was a valuation allowance release resulting in a tax benefit of $1.6 million due to the purchase accounting adjustment for the net deferred tax liability acquired. Furthermore, we do not incur expense or benefit in certain tax free jurisdictions in which we operate.

Income tax expense in the foreign jurisdictions in which we are subject to tax is expected to remain relatively constant due to the cost plus nature of these entities and the relatively consistent operating expenses in each jurisdiction. Fluctuations in world-wide income occur mostly outside of these jurisdictions and therefore have an insignificant effect on our provision for income taxes. We expect this relationship to continue until the time that we either recognize all or a portion of our federal and California deferred tax assets or implement changes to our global operations.

Liquidity and Capital Resources

As of September 30, 2015, we had cash and cash equivalents of $58.1 million, short- and long-term investments of $46.6 million, and net accounts receivable of $41.8 million.

Following is a summary of our working capital and cash and cash equivalents and investments as of September 30, 2015 and December 31, 2014:

Net cash provided by investing activities was $6.6 million for the nine months ended September 30, 2015. Net cash provided by investing activities consisted of $57.5 million in maturities of securities, offset by $45.7 million in purchases of securities, $3.6 million used in our acquisition of Entropic, $1.5 million in purchases of property and equipment and $0.1 million purchases of intangibles. Net cash used in investing activities was $8.3 million for the nine months ended September 30, 2014. Net cash used in investing activities consisted of $36.5 million in purchases of securities and $7.8 million in purchases of property and equipment, offset by $35.9 million in maturities of securities.

Cash Flows from Financing Activities

Net cash provided by financing activities for the nine months ended September 30, 2015 consisted primarily of $6.3 million in net proceeds from issuance of common stock, offset by $4.5 million in minimum tax withholding paid on behalf of employees for restricted stock units, equity issuance costs of $0.7 million and repurchases of common stock of $0.1 million. Net cash used in financing activities for the nine months ended September 30, 2014 consisted primarily of $1.6 million in net proceeds from issuance of common stock, offset by $3.6 million in minimum tax withholding paid on behalf of employees for restricted stock units.

We believe that our $58.1 million of cash and cash equivalents and $46.6 million in short- and long-term investments at September 30, 2015 will be sufficient to fund our projected operating requirements for at least the next twelve months. Our cash and cash equivalents as of September 30, 2015 have been favorably affected by our implementation of an equity-based bonus program. In connection with that bonus program, in August 2015, we issued 0.3 million freely-tradable shares of our Class A common stock in settlement of bonus awards for the January 1, 2015 to June 30, 2015 performance period under our bonus plan. In May 2015, we issued 0.2 million freely-tradable shares of our Class A common stock in settlement of bonus awards for the fiscal 2014 performance period under our bonus plan. In May 2014, we issued 0.6 million freely-tradable shares of our Class A common stock in settlement of bonus awards for the fiscal 2013 performance period under our bonus plan. We expect to implement a similar equity-based plan for the second half of fiscal 2015, but our compensation committee retains discretion to effect payment in cash, stock, or a combination of cash and stock.

Notwithstanding the foregoing, 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.

36

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, 2015, we were not involved in any unconsolidated SPE transactions.

Contractual Obligations

At September 30, 2015, future minimum payments under non-cancelable operating leases, other obligations and inventory purchase obligations are as follows:

	Operating Leases		Other Obligations		Inventory Purchase Obligations
2015 (remaining three months)	$	1,608	$	2,545	$	18,286
2016	6,773		9,538		—
2017	6,025		4,687		—
2018	5,121		700		—
2019	4,774		—		—
Thereafter	12,897		—		—
Total minimum payments:	$	37,198	$	17,470	$	18,286

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Foreign Currency Risk

To date, our international customer and vendor agreements have been denominated mostly 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 and cash equivalents of $58.1 million at September 30, 2015 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.

38

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 and principal financial 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 and principal financial officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this Quarterly Report.

Changes in Internal Control over Financial Reporting

On April 30, 2015, we acquired Entropic and, as a result, we have begun integrating the processes, systems and controls relating to Entropic into our existing system of internal control over financial reporting in accordance with our integration plans. Except for the processes, systems and controls relating to the integration of Entropic, there have not been any changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act during the third quarter ended September 30, 2015 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

Entropic Communications Merger Litigation

The Delaware Actions

Beginning on February 9, 2015, eleven stockholder class action complaints (captioned Langholz v. Entropic Communications, Inc., et al., C.A. No. 10631-VCP (filed Feb. 9, 2015); Tomblin v. Entropic Communications, Inc., C.A. No. 10632-VCP (filed Feb. 9, 2015); Crill v. Entropic Communications, Inc., et al., C.A. No. 10640-VCP (filed Feb. 11, 2015); Wohl v. Entropic Communications, Inc., et al., C.A. No. 10644-VCP (filed Feb. 11, 2015); Parshall v. Entropic Communications, Inc., et al., C.A. No. 10652-VCP (filed Feb. 12, 2015); Saggar v. Padval, et al., C.A. No. 10661-VCP (filed Feb. 13, 2015); Iyer v. Tewksbury, et al., C.A. No. 10665-VCP (filed Feb. 13, 2015); Respler v. Entropic Communications, Inc., et al., C.A. No. 10669-VCP (filed Feb. 17, 2015); Galv. Entropic Communications, Inc., et al., C.A. No. 10671-VCP (filed Feb. 17, 2015); Werbowsky v. Padval, et al.,C.A. No. 10673-VCP (filed Feb. 18, 2015); and Agosti v. Entropic Communications, Inc., C.A. No. 10676-VCP (filed Feb. 18, 2015)) were filed in the Court of Chancery of the State of Delaware on behalf of a putative class of Entropic Communications, Inc. stockholders. The complaints name Entropic, the board of directors of Entropic, MaxLinear, Excalibur Acquisition Corporation, and Excalibur Subsidiary, LLC as defendants. The complaints generally allege that, in connection with the proposed acquisition of Entropic by MaxLinear, the individual defendants breached their fiduciary duties to Entropic stockholders by, among other things, purportedly failing to take steps to maximize the value of Entropic to its stockholders and agreeing to allegedly preclusive deal protection devices in the merger agreement. The complaints further allege that Entropic, MaxLinear, and/or the merger subsidiaries aided and abetted the individual defendants in the alleged breaches of their fiduciary duties. The complaints seek, among other things, an order enjoining the defendants from consummating the proposed transaction, an order declaring the merger agreement unlawful and unenforceable, in the event that the proposed transaction is consummated, an order rescinding it and setting it aside or awarding rescissory damages to the class, imposition of a constructive trust, damages, and/or attorneys’ fees and costs.

On March 27, 2015, plaintiffs Ankur Saggar, Jon Werbowsky, and Angelo Agosti filed an amended class action complaint. Also on March 27, 2015, plaintiffs Martin Wohl and Jeffrey Park filed an amended class action complaint. On April 1, 2015, plaintiff Mark Respler filed an amended class action complaint.

On April 16, 2015, the Court entered an order consolidating the Delaware actions, captioned In re Entropic Communications, Inc. Consolidated Stockholders Litigation, C.A. No. 10631-VCP (the “Consolidated Action”). The April 16, 2015 order appointed plaintiffs Rama Iyer and Jon Werbowsky as Co-Lead Plaintiffs and designated the amended complaint filed by plaintiffs Ankur Saggar, Jon Werbowsky, and Angelo Agosti as the operative complaint (the “Amended Complaint”).

The Amended Complaint names as defendants Entropic, the board of directors of Entropic, the Company, Excalibur Acquisition Corporation, and Excalibur Subsidiary, LLC. The Amended Complaint generally alleges that, in connection with the proposed acquisition of Entropic by the Company, the individual defendants breached their fiduciary duties to Entropic stockholders by, among other things, purportedly failing to maximize the value of Entropic to its stockholders, engaging in a purportedly unfair and conflicted sale process, agreeing to allegedly preclusive deal protection devices in the merger agreement, and allegedly misrepresenting and/or failing to disclose all material information in connection with the proposed transaction. The Amended Complaint further alleges that the Company and the merger subsidiaries aided and abetted the individual defendants in the alleged breaches of their fiduciary duties. The Amended Complaint seeks, among other things: an order declaring the merger agreement unlawful and unenforceable, an order rescinding, to the extent already implemented, the merger agreement, an order enjoining defendants from consummating the proposed transaction, imposition of a constructive trust, and attorneys’ and experts’ fees and costs.

On April 24, 2015, the parties to the Consolidated Action entered into a memorandum of understanding regarding a proposed settlement of the Delaware actions. The proposed settlement is subject to negotiation of the settlement papers by the parties and is subject to court approval after notice and an opportunity to object is provided to the proposed settlement class. There can be no assurance that the parties will reach agreement regarding the final terms of the settlement agreement or that the Court of Chancery will approve the settlement.

Based on the above, the Company has not recorded an accrual for loss contingencies associated with the Delaware actions; determined that an unfavorable outcome is probable or reasonably possible; or determined that the amount or range of any possible loss is reasonably estimable.

CrestaTech Litigation

On January 21, 2014, CrestaTech Technology Corporation, or CrestaTech, filed a complaint for patent infringement against us in the United States District Court of Delaware (the “District Court Litigation”). In its complaint, CrestaTech alleges that we infringe U.S. Patent Nos. 7,075,585 (the “’585 Patent”) and 7,265,792. In addition to asking for compensatory damages, CrestaTech alleges willful infringement and seeks a permanent injunction. CrestaTech also names Sharp Corporation, Sharp Electronics Corp. and VIZIO, Inc. as defendants based upon their alleged use of our television tuners. On January 28, 2014, CrestaTech filed a complaint with the U.S. International Trade Commission, or ITC, again naming us, Sharp, Sharp Electronics, and VIZIO (“the “ITC Investigation”). On May 16, 2014 the ITC granted CrestaTech’s motion to file an amended complaint adding six OEM Respondents, namely, SIO International, Inc., Hon Hai Precision Industry Co., Ltd., Wistron Corp., Wistron Infocomm Technology (America) Corp., Top Victory Investments Ltd. and TPV International (USA), Inc. (collectively, with us, Sharp and VIZIO, the “Company Respondents”). CrestaTech’s ITC complaint alleges a violation of 19 U.S.C. § 1337 through the importation into the United States, the sale for importation, or the sale within the United States after importation of the Company’s accused products that CrestaTech alleges infringe the same two patents asserted in the Delaware action. Through its ITC complaint, CrestaTech seeks an exclusion order preventing entry into the United States of certain of our television tuners and televisions containing such tuners from Sharp, Sharp Electronics, and VIZIO. CrestaTech also seeks a cease and desist order prohibiting the Company Respondents from engaging in the importation into, sale for importation into, the sale after importation of, or otherwise transferring within the United States certain of the Company's television tuners or televisions containing such tuners.

On December 1-5, 2014, the ITC held a trial in the ITC Investigation. On February 27, 2015, the Administrative Law Judge issued a written Initial Determination (“ID”), ruling that the Company Respondents do not violate Section 1337 in connection with CrestaTech’s asserted patents because CrestaTech failed to satisfy the economic prong of the domestic industry requirement pursuant to Section 1337(a)(2). In addition, the ID stated that certain of the our television tuners and televisions incorporating those tuners manufactured and sold by certain customers infringe three claims of the ‘585 Patent, and these three claims were not determined to be invalid. On April 30, 2015, the ITC issued a notice indicating that it intended to review portions of the ID finding no violation of Section 1337, including the ID’s findings of infringement with respect to, and validity of, the ‘585 Patent, and the ID’s finding that CrestaTech failed to establish the existence of a domestic industry within the meaning of Section 1337.

The Commission requested additional briefing from the parties on certain issues under review by the Commission. The ITC has now issued its opinion, which terminates its investigation. The opinion affirmed the findings of the administrative law judge that no violation of Section 1337 had occurred because CrestaTech had failed to establish the economic prong of the domestic industry requirement. The ITC also affirmed the administrative law judge's finding of infringement with respect to the three claims of the '585 Patent that were not held to be invalid. CrestaTech may now appeal the decision of the ITC to the United States Court of Appeals for the Federal Circuit. The District Court Litigation remains stayed pending resolution of any appeal to the ITC. In addition, we have filed four petitions for inter partes review ("IPR") by the US Patent Office of the two CrestaTech patents asserted against us. We cannot predict the outcome of any appeal by CrestaTech, the District Court Litigation, or the IPRs.

In view of the final determination of no violation in the ITC Investigation and the institution of IPR proceedings, the Company has not recorded an accrual for loss contingencies associated with the 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 Entropic and CrestaTech 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.

ITEM 1A. RISK FACTORS

This Quarterly Report on Form 10-Q, or Form 10-Q, including any information incorporated by reference herein, contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, referred to as the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, referred to as the Exchange Act. In some cases, you can identify forward-looking statements by terms such as “may,” “will,” “should,” “expect,” “plan,” “intend,” “forecast,” “anticipate,” “believe,” “estimate,” “predict,” “potential,” “continue” or the negative of these terms or other comparable terminology. The forward-looking statements contained in this Form 10-Q involve known and unknown risks, uncertainties and situations that may cause our or our industry’s actual results, level of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by these statements. These factors include those listed below in this Item 1A and those discussed elsewhere in this Form 10-Q. We encourage investors to review these factors carefully. We may from time to time make additional written and oral forward-looking statements, including statements contained in our filings with the SEC. However, we do not undertake to update any forward-looking statement that may be made from time to time by or on behalf of us.

Before you invest in our securities, you should be aware that our business faces numerous financial and market risks, including those described below, as well as general economic and business risks. The following discussion provides information concerning the material risks and uncertainties that we have identified and believe may adversely affect our business, our financial condition and our results of operations. Before you decide whether to invest in our securities, you should carefully consider these risks and uncertainties, together with all of the other information included in this Quarterly Report on Form 10-Q, the Annual Report on Form 10-K we filed on February 23, 2015, as amended by Amendment No. 1 on Form 10-K/A filed with the SEC on March 12, 2015, and in our other public filings.

On April 30, 2015, we completed our acquisition of Entropic Communications, Inc., or Entropic, and promptly following such acquisition, Entropic merged with and into Excalibur Subsidiary, LLC, with Excalibur Subsidiary, LLC continuing as the surviving entity and changing its name to Entropic Communications, LLC. For the risks relating to our acquisition of Entropic, please refer to the section of these risk factors captioned “Risks Relating to Our Recent Acquisition of Entropic.”

Risks Relating to Our Recent Acquisition of Entropic

Actual financial and operating results could differ materially from any expectations or guidance provided by us concerning future results, including (without limitation) expectations or guidance with respect to the financial impact of any cost savings and other potential synergies resulting from our acquisition of Entropic.

We currently expect to realize material cost savings and other synergies as a result of our acquisition of Entropic, and as a result, we currently believe that the acquisition will be accretive to our earnings per share, excluding upfront non-recurring charges, transaction related expenses, and the amortization of purchased intangible assets. The expectations and guidance we have provided with respect to the potential financial impact of the acquisition are subject to numerous assumptions, however, including assumptions derived from our diligence efforts concerning the status of and prospects for Entropic’s business, and assumptions relating to the near-term prospects for the semiconductor industry generally and the markets for the legacy Entropic products in particular. Additional assumptions we have made relate to numerous matters, including (without limitation) the following:

• projections of future revenues in the legacy Entropic business;

• the anticipated financial performance of legacy Entropic products and products currently in development;

• anticipated cost savings and other synergies associated with the acquisition, including potential revenue synergies;

• the amount of goodwill and intangibles that will result from the acquisition;

• certain other purchase accounting adjustments that we have recorded in our financial statements in connection with the acquisition;

• acquisition costs, including restructuring charges and transactions costs payable to our financial, legal, and accounting advisors;

• our ability to maintain, develop, and deepen relationships with customers of the legacy Entropic business; and

42

We cannot provide any assurances with respect to the accuracy of our assumptions, including our assumptions with respect to future revenues or revenue growth rates, if any, of the legacy Entropic business, and we cannot provide assurances with respect to our ability to realize the cost savings that we currently anticipate. Risks and uncertainties that could cause our actual results to differ materially from currently anticipated results include, but are not limited to, risks relating to our ability to integrate the legacy Entropic business successfully; currently unanticipated additional incremental costs that we may incur in connection with integrating the two companies; risks relating to our ability to continue to realize incremental revenues from the acquisition in the amounts that we currently anticipate; risks relating to the willingness of legacy Entropic customers and other partners to continue to conduct business with MaxLinear; and numerous risks and uncertainties that affect the semiconductor industry generally and the markets for our products and those of the legacy Entropic business specifically. Any failure to integrate the legacy Entropic business successfully and to continue to realize the financial benefits we currently anticipate from the acquisition would have a material adverse impact on our future operating results and financial condition and could materially and adversely affect the trading price or trading volume of our Class A common stock.

Failure to integrate our business and operations successfully with those of Entropic in the expected time-frame or otherwise may adversely affect our operating results and financial condition.

We do not have a substantial history of acquiring other companies and have never pursued an acquisition of the size and complexity of Entropic. The success of the acquisition of Entropic will depend, in substantial part, on our ability to integrate Entropic’s business and operations successfully with those of MaxLinear and to realize fully the anticipated benefits and potential synergies from combining our companies, including, among others, cost savings from eliminating duplicative functions; operational efficiencies in our respective supply chains and in research and development investments; and revenue growth resulting from the addition of Entropic’s product portfolio. If we are unable to achieve these objectives, the anticipated benefits and potential synergies from the acquisition may not be realized fully or at all, or may take longer to realize than expected. Any failure to timely realize these anticipated benefits would have a material adverse effect on our business, operating results, and financial condition.

We completed our acquisition of Entropic in April 2015 and the integration process remains in progress. In connection with the integration process, we could experience the loss of key employees, loss of key customers, decreases in revenues and increases in operating costs, as well as the disruption of our ongoing businesses, any or all of which could limit our ability to achieve the anticipated benefits and potential synergies from the acquisition and have a material adverse effect on our business, operating results, and financial condition.

Our business relationships, including customer relationships, and those of Entropic may be subject to disruption due to uncertainty associated with the acquisition.

In response to the completion of the acquisition, customers, vendors, licensors, and other third parties with whom we do business or Entropic did business or otherwise have relationships may experience uncertainty associated with the acquisition, and this uncertainty could materially affect their decisions with respect to existing or future business relationships with us. Moreover, with respect to Entropic’s prior acquisition of certain television and set-top box assets from Trident Microsystems, Inc. (“Trident”), we were unable to conduct substantial diligence with respect to certain licenses and intellectual property rights because Entropic acquired these assets through Trident’s bankruptcy proceedings. As a result, we are in many instances unable to evaluate the impact of the acquisition on certain assumed contract rights and obligations, including intellectual property rights.

These business relationships may be subject to disruption as customers and others may elect to delay or defer purchase or design-win decisions or switch to other suppliers due to the uncertainty about the direction of our offerings, any perceived unwillingness on our part to support existing legacy Entropic products, or any general perceptions by customers or other third parties that impute operational or business challenges to us arising from the acquisition. In addition, customers or other third parties may attempt to negotiate changes in existing business relationships, which may result in additional obligations imposed on us. These disruptions could have a material adverse effect on our business, operating results, and financial condition. Any loss of customers, customer products, design win opportunities, or other important strategic relationships could have a material adverse effect on our business, operating results, and financial condition and could have a material and adverse effect on the trading price or trading volume of our Class A common stock.

43

We have incurred and expect to continue to incur substantial expenses related to the integration of MaxLinear and Entropic.

We have incurred and expect to continue to incur substantial expenses in connection with integrating the operations, technologies, and business systems of MaxLinear and Entropic. Business systems integration between the two companies requires, and we expect it to continue to require into the foreseeable future, substantial management attention, including integration of information management, purchasing, accounting and finance, sales, payroll and benefits systems and regulatory compliance functions. Numerous factors beyond our control could affect the total cost or the timing of expected integration expenses. Moreover, many of the expenses that will be incurred are by their nature difficult to estimate accurately at the present time. These expenses could, particularly in the near term, reduce the savings that we expect to achieve from the elimination of duplicative expenses and the realization of economies of scale and cost savings related to the integration of the businesses. These integration expenses have resulted in MaxLinear’s taking significant charges against earnings following the completion of the acquisition.

We have recorded goodwill that could become impaired and adversely affect our future operating results.

The acquisition is accounted for as an acquisition by MaxLinear in accordance with accounting principles generally accepted in the United States. Under the acquisition method of accounting, the assets and liabilities of Entropic have been recorded, as of completion, at their respective fair values and added to our assets and liabilities. Our reported financial condition and results of operations after completion of the acquisition reflect Entropic’s balances and results but are not restated retroactively to reflect the historical financial position or results of operations of Entropic for periods prior to the acquisition. As a result, comparisons of future results against prior period results will be more difficult for investors.

Under the acquisition method of accounting, the total purchase price is allocated to Entropic’s tangible assets and liabilities and identifiable intangible assets based on their fair values as of the date of completion of the acquisition. The excess of the purchase price over those fair values is recorded as goodwill. The acquisition has resulted in the creation of goodwill based upon the application of the acquisition method of accounting. To the extent the value of goodwill or intangibles becomes impaired, we may be required to incur material charges relating to such impairment. Any such impairment charge could have a material impact on our operating results in future periods, and the announcement of a material impairment could have an adverse effect on the trading price and trading volume of our Class A common stock.

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, and with providers of physical medium devices for optical interconnect markets. 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 television, set top box, data modems and gateway, satellite low-noise blocker, and optical module manufacturers, some of which may be our customers. Our primary competitors include Silicon Labs, NXP B.V., RDA Microelectronics, Inc., Broadcom Corporation, Rafael Microelectronics, Inc., and Inphi Corporation, M/A-COM Technology Solutions Holdings, Inc., Semtech Corporation, and Qorvo Inc. for our new initiatives into the optical interconnect markets. 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

44

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, satellite, or DTV applications, and thereby potentially provide customers with smaller and cheaper solutions. Some of our targeted customers for our optical interconnect solutions are module makers who are vertically integrated, where we compete with internally supplied components.

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, that have undergone or are subject to pending consolidation and who themselves are dependent on a consolidating set of service provider 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.

For fiscal 2013, one customer accounted for approximately 28% of our net revenue, and our ten largest customers collectively accounted for approximately 72% of our net revenue. For fiscal 2014, one customer accounted for approximately 31% of our net revenue, and our ten largest customers collectively accounted for approximately 67% of our net revenue. For the nine months ended September 30, 2015, two customers accounted for 42% of our net revenue, and our ten largest customers accounted for 76% 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, digital STB video SoCs, DBS ODU, and MoCA® connectivity solutions. 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;

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

• service provider and OEM consolidation across cable, satellite, and fiber markets could result in significant changes to our customers’ technology development and deployment priorities and roadmaps, which could affect our ability to forecast demand accurately and could lead to increased volatility in our business.

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 broadband and pay-TV operator applications, and consolidation among cable and satellite television operators could adversely affect our future revenues and operating results.

For fiscal 2013, revenue directly attributable to cable and satellite operator applications accounted for approximately 68% of our net revenue. For fiscal 2014, revenue directly attributable to these applications accounted for approximately 65% of our net revenue. For the nine months ended September 30, 2015, revenue directly attributable to operator applications

45

accounted for approximately 75% of our net revenue. We currently expect this revenue contribution dynamic among operator, infrastructure and other and legacy SoC applications to be relatively consistent for the remainder of 2015. Delays in the development of, or unexpected developments in the operator applications 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. In addition, consolidation trends among television operators may continue, which could have a material adverse effect on our future operating results and financial condition.

If we fail to penetrate new markets, specifically the market for satellite set-top and gateway boxes and outdoor units, 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, broadband voice and data modems and gateways, and pay-TV set-top boxes and gateways, and to Chinese manufacturers of terrestrial 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, and we have targeted the market for satellite set-top and gateway boxes and outdoor units as one of our next market opportunities. Each of these markets presents distinct and substantial risks. If any of these markets do 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 broadband data modems/gateways and pay-TV and satellite set top boxes and video gateways to represent our largest North American and European target market. The North American and European pay-TV set top box market is dominated by only a few OEMs, including Cisco Systems, Inc., Arris Group, Inc., Pace plc, Humax Co., Ltd., Samsung Electronics Co., Ltd., 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 pay-TV television companies such as Comcast Corporation, Time Warner Cable Inc., DIRECTV, and EchoStar Corporation. 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.

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.

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 we believe have provided us with a significant competitive advantage. For fiscal 2013, our research and development expense was $53.1 million. For fiscal 2014, our research and development expense was $56.6 million. For the nine months ended September 30, 2015, our research and development expense was $62.8 million. In the nine months ended September 30, 2015, 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 28nm 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.

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 and physical medium devices for optical modules may contain defects and bugs when they are first introduced or as new versions are released. We have previously experienced, and may in the future experience, defects and bugs and, in particular, have identified liabilities of several million dollars arising from warranty claims related to legacy Entropic products. Where any of our products, including legacy Entropic products, contain defects or bugs, or have reliability, quality or compatibility problems, we may not be able to successfully correct these

46

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 (as in the case of the legacy Entropic products experiencing warranty claims), 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.

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.

In particular, we believe that we will need to develop new products in part to respond to changing dynamics and trends in our end user markets, including (among other trends) consolidation among cable and satellite operators, potential industry shifts away from the hardware devices and other technologies that incorporate our products, and changes in consumer television viewing habits and how consumers access and receive broadcast content and digital broadband services. We cannot predict how these trends will continue to develop or how or to what extent they may affect our future revenues and operating results. We believe that we will need to continue to make substantial investments in research and development in an attempt to ensure a product roadmap that anticipates these types of changes; however, we cannot provide any assurances that we will accurately predict the direction in which our markets will evolve or that we will be able to develop, market, or sell new products that respond to such changes successfully or in a timely manner, if at all.

We recently settled and are currently a party 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. Third parties have in the past and may in the future assert against us and our customers and distributors their patent and other intellectual property rights to

47

technologies that are important to our business. In particular, from time to time, we receive correspondence from competitors seeking to engage us in discussions concerning potential claims against us, and we receive correspondence from customers seeking indemnification for potential claims related to infringement claims asserted against down-stream users of our products. We investigate these requests as received and could be required to enter license agreements with respect to third party intellectual property rights or indemnify third parties, either of which could have an adverse effect on our future operating results.

On January 21, 2014, CrestaTech Technology Corporation, or CrestaTech, filed a complaint for patent infringement against us in the United States District Court of Delaware (the “District Court Litigation”). In its complaint, CrestaTech alleges that we infringe U.S. Patent Nos. 7,075,585 (the “’585 Patent”) and 7,265,792. In addition to asking for compensatory damages, CrestaTech alleges willful infringement and seeks a permanent injunction. CrestaTech also names Sharp Corporation, Sharp Electronics Corp. and VIZIO, Inc. as defendants based upon their alleged use of our television tuners. On January 28, 2014, CrestaTech filed a complaint with the U.S. International Trade Commission, or ITC, again naming us, Sharp, Sharp Electronics, and VIZIO (“the “ITC Investigation”). On May 16, 2014 the ITC granted CrestaTech’s motion to file an amended complaint adding six OEM Respondents, namely, SIO International, Inc., Hon Hai Precision Industry Co., Ltd., Wistron Corp., Wistron Infocomm Technology (America) Corp., Top Victory Investments Ltd. and TPV International (USA), Inc. (collectively, with us, Sharp and VIZIO, the “Company Respondents”). CrestaTech’s ITC complaint alleges a violation of 19 U.S.C. § 1337 through the importation into the United States, the sale for importation, or the sale within the United States after importation of the Company’s accused products that CrestaTech alleges infringe the same two patents asserted in the Delaware action. Through its ITC complaint, CrestaTech seeks an exclusion order preventing entry into the United States of certain of our television tuners and televisions containing such tuners from Sharp, Sharp Electronics, and VIZIO. CrestaTech also seeks a cease and desist order prohibiting the Company Respondents from engaging in the importation into, sale for importation into, the sale after importation of, or otherwise transferring within the United States certain of the Company's television tuners or televisions containing such tuners.

On December 1-5, 2014, the ITC held a trial in the ITC Investigation. On February 27, 2015, the Administrative Law Judge issued a written Initial Determination (“ID”), ruling that the Company Respondents do not violate Section 1337 in connection with CrestaTech’s asserted patents because CrestaTech failed to satisfy the economic prong of the domestic industry requirement pursuant to Section 1337(a)(2). In addition, the ID stated that certain of the our television tuners and televisions incorporating those tuners manufactured and sold by certain customers infringe three claims of the ‘585 Patent, and these three claims were not determined to be invalid. On April 30, 2015, the ITC issued a notice indicating that it intended to review portions of the ID finding no violation of Section 1337, including the ID’s findings of infringement with respect to, and validity of, the ‘585 Patent, and the ID’s finding that CrestaTech failed to establish the existence of a domestic industry within the meaning of Section 1337.

The Commission requested additional briefing from the parties on certain issues under review by the Commission. The ITC has now issued its opinion, which terminates its investigation. The opinion affirmed the findings of the administrative law judge that no violation of Section 1337 had occurred because CrestaTech had failed to establish the economic prong of the domestic industry requirement. The ITC also affirmed the administrative law judge's finding of infringement with respect to the three claims of the '585 Patent that were not held to be invalid. CrestaTech may now appeal the decision of the ITC to the United States Court of Appeals for the Federal Circuit. The District Court Litigation remains stayed pending resolution of any appeal to the ITC. In addition, we have filed four petitions for inter partes review ("IPR") by the US Patent Office of the two CrestaTech patents asserted against us. We cannot predict the outcome of any appeal by CrestaTech, the District Court Litigation, or the IPRs.

In addition, we have filed four petitions for inter partes review (“IPR”) by the U.S. Patent Office of the two CrestaTech patents asserted against us. The Patent Trial and Appeal Board did not institute two of these IPRs as being redundant to IPRs filed by another party that are already underway for the same CrestaTech patent.  The remaining two petitions were instituted or instituted-in-part and, together with the IPRs filed by third parties, there are currently six pending IPR proceedings involving the two CrestaTech patents asserted against us.  The two specific claims mentioned above are included in at least one of the review proceedings instituted and currently pending against CrestaTech. 

Claims that our products, processes or technology infringe third-party intellectual property rights, regardless of their merit or resolution and including the CrestaTech claims, are 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. In order to maintain our relationships with existing customers and secure business from

48

new customers, we have been required from time to time to provide additional assurances beyond our standard terms. If any 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;

• 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, 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 as has occurred with

49

CrestaTech, 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.

When we settled 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.

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 nine months ended September 30, 2015, sales of our RF receiver products used in digital terrestrial television applications, or DTT, including digital televisions, PCTV, IPTV, terrestrial set top boxes, and terrestrial receivers in satellite video gateways represented a declining, but not insignificant, 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. Many countries in Eastern Europe and Latin America are expected to convert to digital television by the end of 2018, with other countries targeting dates as late as 2024. 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 ongoing global transition to digital TV standards does not continue to progress or experiences significant delays, 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.

Global 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.

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. Global economic volatility and economic volatility in the specific markets in which the devices that incorporate our products are ultimately sold can cause extreme difficulties for our customers and third-party vendors in accurately forecasting and planning future business activities. This unpredictability could cause our customers to reduce spending on our products, which would delay and lengthen sales cycles. Furthermore, during challenging economic times our customers may face challenges in gaining timely access to sufficient credit, which could impact their ability to make timely payments to us. These events, together with economic volatility that may face the broader economy and, in particular, the semiconductor and communications industries, may adversely affect, our business, particularly to the extent that consumers decrease their discretionary spending for devices deploying our products.

50

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, Semiconductor Manufacturing International Corporation, or SMIC, Taiwan Semiconductor Manufacturing Corp, or TSMC, and Jazz Semiconductor at foundries in Taiwan, Singapore, Malaysia, China, and the United States. 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 China, 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, SMIC, TSMC and Jazz Semiconductor. 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

51

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.

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.

We may have difficulty accurately predicting our future revenue and appropriately budgeting our expenses particularly as we seek to enter new markets where we may not have prior experience.

Our recent operating history has focused on developing integrated circuits for specific terrestrial and cable television applications, and as part of our strategy, we seek to expand our addressable market into new product categories. For example, we have recently expanded into the market for satellite set-top and gateway boxes and outdoor units and physical medium devices for the optical interconnect markets. Our limited operating experience in new markets or potential markets we may enter, combined with the rapidly evolving nature of our markets in general, 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 $97.7 million in 2012 to approximately $119.6 million in 2013 and approximately $133.1 million in 2014. 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.

52

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.

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, Central 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.

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 and physical medium devices for optical modules, 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. For fiscal 2013, sales through distributors accounted for 29% of our net revenue. For fiscal 2014, sales through distributors accounted for 28% of our net revenue. For the nine months ended September 30, 2015, sales through distributors accounted for 14% of our net revenue. 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 our distributors where revenue is not recognized, we record 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 record 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 our distributors may result in the realization of a different amount of profit included our future consolidated statements of operations than the amount recorded as deferred profit in our consolidated balance sheets.

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 through 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.

53

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, customers may decide to cancel or change their 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, MoCA SoCs, DBS-ODU SoCs, and physical medium devices for optical modules 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. 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 36 months for the cable operator 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;

54

• 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;

• impairment of long-lived assets, including masks and production equipment; 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.

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. Any future downturns may result in diminished product demand, production overcapacity, high inventory levels and accelerated erosion of average selling prices. 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, MoCA SoCs, DBS-ODU SoCs, and physical medium devices for optical modules. None of our third-party foundry or assembly contractors has provided assurances that adequate capacity will be available to us in the future. A significant downturn or upturn could have a material adverse effect on our business and operating results.

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.

55

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.

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 or unanticipated tax obligations 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. We cannot determine whether any legislative proposals may be enacted into law or what, if any, changes may be made to such proposals prior to their being enacted into law. If U.S. or international 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.

The Federal examination by the Internal Revenue Service for the years 2010 and 2011 was completed during the three months ended March 31, 2014. The Company is still subject to examination for 2012 through 2014. In the event we are determined to have any unaccrued tax obligation arising from future audits, our operating results would be adversely affected.

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.

56

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. Products shipped to Asia accounted for 90% of our net revenue in the nine months ended September 30, 2015. In addition, approximately 29% 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;

• 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 Singapore, China and Malaysia, substantially all of our products undergo packaging and final testing 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.

57

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, Malaysia and China, 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.

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, import/export control regulations, and the Foreign Corrupt Practices Act. These regulations are complex, change frequently and have generally become more stringent over time. We may be required to incur significant costs to comply with these regulations or to remedy violations. Any failure by us to comply with applicable government regulations could result in cessation of our operations or portions of our operations, product recalls or impositions of fines and restrictions on our ability to conduct our operations. In addition, because many of our products are regulated or sold into regulated industries, we must comply with additional regulations in marketing our products.

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

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

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.

In addition to our acquisitions of Entropic and Physpeed, we may, from time to time, make additional business acquisitions or investments, which involve significant risks.

In addition to the acquisitions of Entropic, which we completed in the second quarter of fiscal 2015, and Physpeed, which we completed in the fourth quarter of fiscal 2014, we may, from time to time, make acquisitions, enter into alliances or make investments in other businesses to complement our existing product offerings, augment our market coverage or enhance our technological capabilities. However, any such transactions could result in:

• issuances of equity securities dilutive to our existing stockholders;

• substantial cash payments;

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

• large one-time write-offs;

• amortization expenses related to intangible assets;

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

58

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

• adverse tax consequences; and

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

Additionally, in periods subsequent to an acquisition, we must evaluate goodwill and acquisition-related intangible assets for impairment. If such assets are found to be impaired, they will be written down to estimated fair value, with a charge against earnings.

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

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

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

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

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

• hiring additional management and other critical personnel;

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

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

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

• the geographic distance between the companies;

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

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

We may be subject to information technology failures, including data protection breaches and cyber-attacks, that could disrupt our operations, damage our reputation and adversely affect our business, operations, and financial results.

We rely on our information technology systems for the effective operation of our business and for the secure maintenance and storage of confidential data relating to our business and third party businesses. Although we have implemented security controls to protect our information technology systems, experienced programmers or hackers may be able to penetrate our security controls, and develop and deploy viruses, worms and other malicious software programs that compromise our confidential information or that of third parties and cause a disruption or failure of our information technology systems. Any such compromise of our information technology systems could result in the unauthorized publication of our confidential business or proprietary information, result in the unauthorized release of customer, supplier or employee data, result in a violation of privacy or other laws, expose us to a risk of litigation, or damage our reputation. The cost and operational consequences of implementing further data protection measures either as a response to specific breaches or as a result of evolving risks, could be significant. In addition, our inability to use or access our information systems at critical points in time could adversely affect the timely and efficient operation of our business. Any delayed sales, significant costs or lost customers resulting from these technology failures could adversely affect our business, operations and financial results.

59

Third parties with which we conduct business, such as foundries, assembly and test contractors, and distributors, have access to certain portions of our sensitive data. In the event that these third parties do not properly safeguard our data that they hold, security breaches could result and negatively impact our business, operations and financial results.

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.

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.

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:

60

• 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, including with respect to transactions involving a change of control, 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. In addition to the additional voting rights granted to holders of our Class B common stock, which is held principally by certain of our executive officers and founders, we have entered change of control agreements with our executive officers, which could have an adverse effect on a third party’s willingness to consider acquiring us, either because it may be more difficult to retain key employees with change of control benefits or because of the incremental cost associated with these benefits.

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

As of September 30, 2015, our founders who are existing employees of the Company, including our Chairman, President and Chief Executive Officer, Dr. Seendripu, together control approximately 11% of our outstanding capital stock, representing approximately 50% 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 our management and affairs 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 MaxLinear or its assets, for the foreseeable future.

Our management team may use our available cash, cash equivalents, and liquid investment assets in ways with which you may not agree or in ways which may not yield a return.

We use our cash, cash equivalents, and liquid investment assets for general corporate purposes, including working capital. We may also use a portion of these assets to acquire complementary businesses, products, services or technologies. Our management has considerable discretion in the application of our cash, cash equivalents, and investment resources, and you will not have the opportunity to assess whether these liquid assets are being used in a manner that you deem best to maximize your return. We may use our available resources for corporate purposes that do not increase our operating results or market value. In addition, our cash, cash equivalents, and liquid investment resources 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, our President 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;

• 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 Quarterly Report on Form 10-Q 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;

62

• 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;

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

• 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, 2015, we had 54.7 million shares of Class A common stock and 6.8 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.

We have filed registration statements on Form S-8 under the Securities Act to register 16.9 million shares of our Class A common stock for issuance under our 2010 Equity Incentive Plan and 2010 Employee Stock Purchase Plan in addition to 3.2 million awards that were assumed and remain outstanding in connection with the Entropic acquisition. 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 holder.

Our Executive Incentive Bonus Plan permits the settlement of awards under the plan in the form of shares of its Class A common stock. For the 2013 performance period, actual awards under the Executive Incentive Bonus Plan were settled in Class A common stock issued under our 2010 Equity Incentive Plan, as amended, with the number of shares issuable to plan participants determined based on the closing sales price of our Class A common stock as determined in trading on the New York Stock Exchange on May 9, 2014. Additionally, we settled all bonus awards for all other employees for the 2013 performance period in shares of its Class A common stock. We issued 0.6 million shares of our Class A common stock for the 2013

63

performance period upon settlement of the bonus awards on May 9, 2014. We issued 0.2 million shares of our Class A common stock for the 2014 performance period upon settlement of the bonus awards on May 14, 2015. We issued 0.3 million shares of our Class A common stock for the January 1, 2015 to June 30, 2015 performance period upon settlement of the bonus awards on August 20, 2015. These shares may be freely sold in the public market immediately following the issuance of such shares and the issuance of such shares may have an adverse effect on our share price once they are issued.

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 nine months ended September 30, 2015, we issued an aggregate of 0.07 million 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 $0.1 million in the nine months ended September 30, 2015 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, 2015, options to purchase an aggregate of 1.2 million 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.

Earnings Per Share [Abstract]

Net Loss Per Share

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

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 integrated circuits for broadband communication and data center, metro, and long-haul transport network 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 cable and terrestrial and satellite set top boxes, DOCSIS data and voice gateways, hybrid analog and digital televisions, satellite low-noise blocker transponders or outdoor units and optical modules for data center, metro, and long-haul transport network applications. The Company is a fabless semiconductor company focusing its resources on the design, sales and marketing of its products.

Acquisition of Entropic Communications, Inc.

On April 30, 2015, the Company completed its acquisition of Entropic Communications, Inc. (Entropic). Pursuant to the terms of the merger agreement dated as of February 3, 2015, by and among the Company, Entropic, and two wholly-owned subsidiaries of the Company, all of the Entropic outstanding shares were converted into the right to receive consideration consisting of cash and shares of the Company’s Class A common stock. The Company paid an aggregate of $111.1 million and issued an aggregate of 20.4 million shares of the Company’s Class A common stock, to the stockholders of Entropic. In addition, the Company assumed all outstanding Entropic stock options and unvested restricted stock units that were held by continuing service providers (as defined in the merger agreement). The Company used Entropic’s cash and cash equivalents to fund a significant portion of the cash portion of the merger consideration and, to a lesser extent, its own cash and cash equivalents. The Company has made all of the material remaining disclosures required by ASC 805-10-50-2, Business Combinations. See Note 3.

In connection with the Company’s acquisition of Entropic and to address issues primarily relating to the integration of the Company and Entropic businesses, the Company terminated the employment of  73 Entropic employees during the nine months endedSeptember 30, 2015. See Note 4.

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.

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, or GAAP, for complete financial statements. In the opinion of management, all adjustments, which include all normal recurring adjustments, considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015. 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, 2014 included in the Annual Report on Form 10-K filed by the Company with the Securities and Exchange Commission, or SEC, on February 23, 2015, as amended by Amendment No. 1 on Form 10-K/A filed with the SEC on March 12, 2015.

Use of Estimates

The preparation of unaudited consolidated financial statements in conformity with U.S. GAAP 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) collectability 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 approximately 14% of net revenue for the three and nine months ended September 30, 2015. Revenues from the Company’s distributors accounted for 30% and 28% of net revenue for the three and nine months ended September 30, 2014, 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 through 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 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 amount of these reductions is based on specific criteria included in the agreements and other factors known at the time. The Company accrues 100% of potential price protection adjustments at the time of sale and does not apply a breakage factor. The Company reverses the accrual for unclaimed price protection amounts as specific programs contractually end or when the Company believes unclaimed amounts are no longer subject to payment and will not be paid. See Note 6 for a summary of the Company's price protection activity.

Business Combinations

The Company applies the provisions of ASC 805, Business Combinations, in the accounting for its acquisitions. It requires the Company to recognize separately from goodwill the assets acquired and the liabilities assumed, at the acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While the Company uses its best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date as well as contingent consideration, where applicable, its estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the consolidated statements of operations.

Costs to exit or restructure certain activities of an acquired company or the Company's internal operations are accounted for as termination and exit costs pursuant to ASC 420, Exit or Disposal Cost Obligations, and are accounted for separately from the business combination. A liability for costs associated with an exit or disposal activity is recognized and measured at its fair value in the consolidated statement of operations in the period in which the liability is incurred. When estimating the fair value of facility restructuring activities, assumptions are applied regarding estimated sub-lease payments to be received, which can differ materially from actual results. This may require the Company to revise its initial estimates which may materially affect the results of operations and financial position in the period the revision is made.

For a given acquisition, the Company may identify certain pre-acquisition contingencies as of the acquisition date and may extend its review and evaluation of these pre-acquisition contingencies throughout the measurement period in order to obtain sufficient information to assess whether the Company includes these contingencies as a part of the fair value estimates of assets acquired and liabilities assumed and, if so, to determine their estimated amounts.

If the Company cannot reasonably determine the fair value of a pre-acquisition contingency (non-income tax related) by the end of the measurement period, which is generally the case given the nature of such matters, the Company will recognize an asset or a liability for such pre-acquisition contingency if: (i) it is probable that an asset existed or a liability had been incurred at the acquisition date and (ii) the amount of the asset or liability can be reasonably estimated. Subsequent to the measurement period, changes in estimates of such contingencies will affect earnings and could have a material effect on results of operations and financial position.

In addition, uncertain tax positions and tax related valuation allowances assumed in connection with a business combination are initially estimated as of the acquisition date. The Company reevaluates these items quarterly based upon facts and circumstances that existed as of the acquisition date with any adjustments to the preliminary estimates being recorded to goodwill if identified within the measurement period. Subsequent to the measurement period or final determination of the tax allowance’s or contingency’s estimated value, whichever comes first, changes to these uncertain tax positions and tax related valuation allowances will affect the provision for income taxes in the consolidated statement of operations and could have a material impact on the results of operations and financial position.

Litigation and Settlement Costs

Legal costs are expensed as incurred. The Company is involved in disputes, litigation and other legal actions in the ordinary course of business. The Company continually evaluates uncertainties associated with litigation and records a charge equal to at least the minimum estimated liability for a loss contingency when both of the following conditions are met: (i) information available prior to issuance of the financial statements indicates that it is probable that an asset had been impaired or a liability had been incurred at the date of the financial statements and (ii) the loss or range of loss can be reasonably estimated.

Goodwill and Intangible Assets

Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the acquired net tangible and intangible assets. Intangible assets represent purchased intangible assets including developed technology and in-process research and development, or IPR&D, and technologies acquired or licensed from other companies. Purchased intangible assets with definitive lives are capitalized and amortized over their estimated useful lives. Technologies acquired or licensed from other companies are capitalized and amortized over the lesser of the terms of the agreement, or estimated useful life. The Company capitalizes IPR&D projects acquired as part of a business combination. On completion of each project, IPR&D assets are reclassified to developed technology and amortized over their estimated useful lives.

Impairment of Goodwill and Long-Lived Assets

Goodwill is the excess of the purchase price over the fair value of identifiable net assets acquired in business combinations accounted for under the purchase method. Goodwill is not amortized but is tested for impairment using a two-step method. Step one is the identification of potential impairment. This involves comparing the fair value of each reporting unit, which the Company has determined to be the entity itself, with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds the carrying amount, the goodwill of the reporting unit is considered not impaired and the second step of the impairment test is unnecessary. If the carrying amount of a reporting unit exceeds its fair value, the second step of the impairment test is performed to measure the amount of impairment loss, if any. The Company tests by reporting unit, goodwill and other indefinite-lived intangible assets for impairment as of October 31 or more frequently if it believes indicators of impairment exist.

During development, IPR&D is not subject to amortization and is tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. The Company reviews indefinite-lived intangible assets for impairment as of October 31, the date of its annual goodwill impairment review or whenever events or changes in circumstances indicate the carrying value may not be recoverable. Recoverability of indefinite-lived intangible assets is measured by comparing the carrying amount of the asset to the future discounted cash flows that asset is expected to generate. Once an IPR&D project is complete, it becomes a definite lived intangible asset and is evaluated for impairment both immediately prior to its change in classification and thereafter in accordance with the Company's policy for long-lived assets.

The Company regularly reviews the carrying amount of its long-lived assets, as well as the useful lives, to determine whether indicators of impairment may exist which warrant adjustments to carrying values or estimated useful lives. An impairment loss would be recognized when the sum of the expected future undiscounted net cash flows is less than the carrying amount of the asset. Should impairment exist, the impairment loss would be measured based on the excess of the carrying amount of the asset over the asset’s fair value.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board, or FASB, issued new accounting guidance related to revenue recognition. This new standard will replace all current U.S. GAAP guidance on this topic and eliminate all industry-specific guidance. The new revenue recognition standard provides a unified model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. This guidance will be effective for the Company beginning in the first quarter of fiscal year 2018 and can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. The Company is evaluating the impact of adopting this new accounting standard on its financial statements.

In August 2014, the FASB issued new accounting guidance related to the disclosures around going concern. The new standard provides guidance around management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures. This guidance will be effective for the Company beginning in the first quarter of fiscal year 2017. Early adoption is permitted. The Company does not expect the adoption of this standard to significantly impact its financial statements.

Entropic Communications Merger Litigation

The Delaware Actions

Beginning on February 9, 2015, eleven stockholder class action complaints (captioned Langholz v. Entropic Communications, Inc., et al., C.A. No. 10631-VCP (filed Feb. 9, 2015); Tomblin v. Entropic Communications, Inc., C.A. No. 10632-VCP (filed Feb. 9, 2015); Crill v. Entropic Communications, Inc., et al., C.A. No. 10640-VCP (filed Feb. 11, 2015); Wohl v. Entropic Communications, Inc., et al., C.A. No. 10644-VCP (filed Feb. 11, 2015); Parshall v. Entropic Communications, Inc., et al., C.A. No. 10652-VCP (filed Feb. 12, 2015); Saggar v. Padval, et al., C.A. No. 10661-VCP (filed Feb. 13, 2015); Iyer v. Tewksbury, et al., C.A. No. 10665-VCP (filed Feb. 13, 2015); Respler v. Entropic Communications, Inc., et al., C.A. No. 10669-VCP (filed Feb. 17, 2015); Galv. Entropic Communications, Inc., et al., C.A. No. 10671-VCP (filed Feb. 17, 2015); Werbowsky v. Padval, et al.,C.A. No. 10673-VCP (filed Feb. 18, 2015); and Agosti v. Entropic Communications, Inc., C.A. No. 10676-VCP (filed Feb. 18, 2015)) were filed in the Court of Chancery of the State of Delaware on behalf of a putative class of Entropic Communications, Inc. stockholders. The complaints name Entropic, the board of directors of Entropic, MaxLinear, Excalibur Acquisition Corporation, and Excalibur Subsidiary, LLC as defendants. The complaints generally allege that, in connection with the proposed acquisition of Entropic by MaxLinear, the individual defendants breached their fiduciary duties to Entropic stockholders by, among other things, purportedly failing to take steps to maximize the value of Entropic to its stockholders and agreeing to allegedly preclusive deal protection devices in the merger agreement. The complaints further allege that Entropic, MaxLinear, and/or the merger subsidiaries aided and abetted the individual defendants in the alleged breaches of their fiduciary duties. The complaints seek, among other things, an order enjoining the defendants from consummating the proposed transaction, an order declaring the merger agreement unlawful and unenforceable, in the event that the proposed transaction is consummated, an order rescinding it and setting it aside or awarding rescissory damages to the class, imposition of a constructive trust, damages, and/or attorneys’ fees and costs.

On March 27, 2015, plaintiffs Ankur Saggar, Jon Werbowsky, and Angelo Agosti filed an amended class action complaint. Also on March 27, 2015, plaintiffs Martin Wohl and Jeffrey Park filed an amended class action complaint. On April 1, 2015, plaintiff Mark Respler filed an amended class action complaint.

On April 16, 2015, the Court entered an order consolidating the Delaware actions, captioned In re Entropic Communications, Inc. Consolidated Stockholders Litigation, C.A. No. 10631-VCP (the “Consolidated Action”). The April 16, 2015 order appointed plaintiffs Rama Iyer and Jon Werbowsky as Co-Lead Plaintiffs and designated the amended complaint filed by plaintiffs Ankur Saggar, Jon Werbowsky, and Angelo Agosti as the operative complaint (the “Amended Complaint”).

The Amended Complaint names as defendants Entropic, the board of directors of Entropic, the Company, Excalibur Acquisition Corporation, and Excalibur Subsidiary, LLC. The Amended Complaint generally alleges that, in connection with the proposed acquisition of Entropic by the Company, the individual defendants breached their fiduciary duties to Entropic stockholders by, among other things, purportedly failing to maximize the value of Entropic to its stockholders, engaging in a purportedly unfair and conflicted sale process, agreeing to allegedly preclusive deal protection devices in the merger agreement, and allegedly misrepresenting and/or failing to disclose all material information in connection with the proposed transaction. The Amended Complaint further alleges that the Company and the merger subsidiaries aided and abetted the individual defendants in the alleged breaches of their fiduciary duties. The Amended Complaint seeks, among other things: an order declaring the merger agreement unlawful and unenforceable, an order rescinding, to the extent already implemented, the merger agreement, an order enjoining defendants from consummating the proposed transaction, imposition of a constructive trust, and attorneys’ and experts’ fees and costs.

On April 24, 2015, the parties to the Consolidated Action entered into a memorandum of understanding regarding a proposed settlement of the Delaware actions. The proposed settlement is subject to negotiation of the settlement papers by the parties and is subject to court approval after notice and an opportunity to object is provided to the proposed settlement class. There can be no assurance that the parties will reach agreement regarding the final terms of the settlement agreement or that the Court of Chancery will approve the settlement.

Based on the above, the Company has not recorded an accrual for loss contingencies associated with the Delaware actions; determined that an unfavorable outcome is probable or reasonably possible; or determined that the amount or range of any possible loss is reasonably estimable.

CrestaTech Litigation

On January 21, 2014, CrestaTech Technology Corporation, or CrestaTech, filed a complaint for patent infringement against us in the United States District Court of Delaware (the “District Court Litigation”). In its complaint, CrestaTech alleges that we infringe U.S. Patent Nos. 7,075,585 (the “’585 Patent”) and 7,265,792. In addition to asking for compensatory damages, CrestaTech alleges willful infringement and seeks a permanent injunction. CrestaTech also names Sharp Corporation, Sharp Electronics Corp. and VIZIO, Inc. as defendants based upon their alleged use of our television tuners. On January 28, 2014, CrestaTech filed a complaint with the U.S. International Trade Commission, or ITC, again naming us, Sharp, Sharp Electronics, and VIZIO (“the “ITC Investigation”). On May 16, 2014 the ITC granted CrestaTech’s motion to file an amended complaint adding six OEM Respondents, namely, SIO International, Inc., Hon Hai Precision Industry Co., Ltd., Wistron Corp., Wistron Infocomm Technology (America) Corp., Top Victory Investments Ltd. and TPV International (USA), Inc. (collectively, with us, Sharp and VIZIO, the “Company Respondents”). CrestaTech’s ITC complaint alleges a violation of 19 U.S.C. § 1337 through the importation into the United States, the sale for importation, or the sale within the United States after importation of the Company’s accused products that CrestaTech alleges infringe the same two patents asserted in the Delaware action. Through its ITC complaint, CrestaTech seeks an exclusion order preventing entry into the United States of certain of our television tuners and televisions containing such tuners from Sharp, Sharp Electronics, and VIZIO. CrestaTech also seeks a cease and desist order prohibiting the Company Respondents from engaging in the importation into, sale for importation into, the sale after importation of, or otherwise transferring within the United States certain of the Company's television tuners or televisions containing such tuners.

On December 1-5, 2014, the ITC held a trial in the ITC Investigation. On February 27, 2015, the Administrative Law Judge issued a written Initial Determination (“ID”), ruling that the Company Respondents do not violate Section 1337 in connection with CrestaTech’s asserted patents because CrestaTech failed to satisfy the economic prong of the domestic industry requirement pursuant to Section 1337(a)(2). In addition, the ID stated that certain of the our television tuners and televisions incorporating those tuners manufactured and sold by certain customers infringe three claims of the ‘585 Patent, and these three claims were not determined to be invalid. On April 30, 2015, the ITC issued a notice indicating that it intended to review portions of the ID finding no violation of Section 1337, including the ID’s findings of infringement with respect to, and validity of, the ‘585 Patent, and the ID’s finding that CrestaTech failed to establish the existence of a domestic industry within the meaning of Section 1337.

The Commission requested additional briefing from the parties on certain issues under review by the Commission. The ITC has now issued its opinion, which terminates its investigation. The opinion affirmed the findings of the administrative law judge that no violation of Section 1337 had occurred because CrestaTech had failed to establish the economic prong of the domestic industry requirement. The ITC also affirmed the administrative law judge's finding of infringement with respect to the three claims of the '585 Patent that were not held to be invalid. CrestaTech may now appeal the decision of the ITC to the United States Court of Appeals for the Federal Circuit. The District Court Litigation remains stayed pending resolution of any appeal to the ITC. In addition, we have filed four petitions for inter partes review ("IPR") by the US Patent Office of the two CrestaTech patents asserted against us. We cannot predict the outcome of any appeal by CrestaTech, the District Court Litigation, or the IPRs.

In addition, we have filed four petitions for inter partes review (“IPR”) by the U.S. Patent Office of the two CrestaTech patents asserted against us. The Patent Trial and Appeal Board did not institute two of these IPRs as being redundant to IPRs filed by another party that are already underway for the same CrestaTech patent.  The remaining two petitions were instituted or instituted-in-part and, together with the IPRs filed by third parties, there are currently six pending IPR proceedings involving the two CrestaTech patents asserted against us.  The two specific claims mentioned above are included in at least one of the review proceedings instituted and currently pending against CrestaTech. 

In view of the final determination of no violation in the ITC Investigation and the institution of IPR proceedings, the Company has not recorded an accrual for loss contingencies associated with the 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Description of Business

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 integrated circuits for broadband communication and data center, metro, and long-haul transport network 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 cable and terrestrial and satellite set top boxes, DOCSIS data and voice gateways, hybrid analog and digital televisions, satellite low-noise blocker transponders or outdoor units and optical modules for data center, metro, and long-haul transport network 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.

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, or GAAP, for complete financial statements. In the opinion of management, all adjustments, which include all normal recurring adjustments, considered necessary for a fair presentation have been included. Operating results for the three and nine months ended September 30, 2015 are not necessarily indicative of the results that may be expected for the year ending December 31, 2015. 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, 2014 included in the Annual Report on Form 10-K filed by the Company with the Securities and Exchange Commission, or SEC, on February 23, 2015, as amended by Amendment No. 1 on Form 10-K/A filed with the SEC on March 12, 2015.

Use of Estimates

Use of Estimates

The preparation of unaudited consolidated financial statements in conformity with U.S. GAAP 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) collectability 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 approximately 14% of net revenue for the three and nine months ended September 30, 2015. Revenues from the Company’s distributors accounted for 30% and 28% of net revenue for the three and nine months ended September 30, 2014, 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 through 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 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 amount of these reductions is based on specific criteria included in the agreements and other factors known at the time. The Company accrues 100% of potential price protection adjustments at the time of sale and does not apply a breakage factor. The Company reverses the accrual for unclaimed price protection amounts as specific programs contractually end or when the Company believes unclaimed amounts are no longer subject to payment and will not be paid. See Note 6 for a summary of the Company's price protection activity.

Business Combinations

Business Combinations

The Company applies the provisions of ASC 805, Business Combinations, in the accounting for its acquisitions. It requires the Company to recognize separately from goodwill the assets acquired and the liabilities assumed, at the acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While the Company uses its best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date as well as contingent consideration, where applicable, its estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, the Company records adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the consolidated statements of operations.

Costs to exit or restructure certain activities of an acquired company or the Company's internal operations are accounted for as termination and exit costs pursuant to ASC 420, Exit or Disposal Cost Obligations, and are accounted for separately from the business combination. A liability for costs associated with an exit or disposal activity is recognized and measured at its fair value in the consolidated statement of operations in the period in which the liability is incurred. When estimating the fair value of facility restructuring activities, assumptions are applied regarding estimated sub-lease payments to be received, which can differ materially from actual results. This may require the Company to revise its initial estimates which may materially affect the results of operations and financial position in the period the revision is made.

For a given acquisition, the Company may identify certain pre-acquisition contingencies as of the acquisition date and may extend its review and evaluation of these pre-acquisition contingencies throughout the measurement period in order to obtain sufficient information to assess whether the Company includes these contingencies as a part of the fair value estimates of assets acquired and liabilities assumed and, if so, to determine their estimated amounts.

If the Company cannot reasonably determine the fair value of a pre-acquisition contingency (non-income tax related) by the end of the measurement period, which is generally the case given the nature of such matters, the Company will recognize an asset or a liability for such pre-acquisition contingency if: (i) it is probable that an asset existed or a liability had been incurred at the acquisition date and (ii) the amount of the asset or liability can be reasonably estimated. Subsequent to the measurement period, changes in estimates of such contingencies will affect earnings and could have a material effect on results of operations and financial position.

In addition, uncertain tax positions and tax related valuation allowances assumed in connection with a business combination are initially estimated as of the acquisition date. The Company reevaluates these items quarterly based upon facts and circumstances that existed as of the acquisition date with any adjustments to the preliminary estimates being recorded to goodwill if identified within the measurement period. Subsequent to the measurement period or final determination of the tax allowance’s or contingency’s estimated value, whichever comes first, changes to these uncertain tax positions and tax related valuation allowances will affect the provision for income taxes in the consolidated statement of operations and could have a material impact on the results of operations and financial position

Litigation and Settlement Costs

Litigation and Settlement Costs

Legal costs are expensed as incurred. The Company is involved in disputes, litigation and other legal actions in the ordinary course of business. The Company continually evaluates uncertainties associated with litigation and records a charge equal to at least the minimum estimated liability for a loss contingency when both of the following conditions are met: (i) information available prior to issuance of the financial statements indicates that it is probable that an asset had been impaired or a liability had been incurred at the date of the financial statements and (ii) the loss or range of loss can be reasonably estimated.

Goodwill and Intangible Assets

Goodwill and Intangible Assets

Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the acquired net tangible and intangible assets. Intangible assets represent purchased intangible assets including developed technology and in-process research and development, or IPR&D, and technologies acquired or licensed from other companies. Purchased intangible assets with definitive lives are capitalized and amortized over their estimated useful lives. Technologies acquired or licensed from other companies are capitalized and amortized over the lesser of the terms of the agreement, or estimated useful life. The Company capitalizes IPR&D projects acquired as part of a business combination. On completion of each project, IPR&D assets are reclassified to developed technology and amortized over their estimated useful lives.

Impairment of Goodwill and Long-Lived Assets

Impairment of Goodwill and Long-Lived Assets

Goodwill is the excess of the purchase price over the fair value of identifiable net assets acquired in business combinations accounted for under the purchase method. Goodwill is not amortized but is tested for impairment using a two-step method. Step one is the identification of potential impairment. This involves comparing the fair value of each reporting unit, which the Company has determined to be the entity itself, with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds the carrying amount, the goodwill of the reporting unit is considered not impaired and the second step of the impairment test is unnecessary. If the carrying amount of a reporting unit exceeds its fair value, the second step of the impairment test is performed to measure the amount of impairment loss, if any. The Company tests by reporting unit, goodwill and other indefinite-lived intangible assets for impairment as of October 31 or more frequently if it believes indicators of impairment exist.

During development, IPR&D is not subject to amortization and is tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. The Company reviews indefinite-lived intangible assets for impairment as of October 31, the date of its annual goodwill impairment review or whenever events or changes in circumstances indicate the carrying value may not be recoverable. Recoverability of indefinite-lived intangible assets is measured by comparing the carrying amount of the asset to the future discounted cash flows that asset is expected to generate. Once an IPR&D project is complete, it becomes a definite lived intangible asset and is evaluated for impairment both immediately prior to its change in classification and thereafter in accordance with the Company's policy for long-lived assets.

The Company regularly reviews the carrying amount of its long-lived assets, as well as the useful lives, to determine whether indicators of impairment may exist which warrant adjustments to carrying values or estimated useful lives. An impairment loss would be recognized when the sum of the expected future undiscounted net cash flows is less than the carrying amount of the asset. Should impairment exist, the impairment loss would be measured based on the excess of the carrying amount of the asset over the asset’s fair value.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board, or FASB, issued new accounting guidance related to revenue recognition. This new standard will replace all current U.S. GAAP guidance on this topic and eliminate all industry-specific guidance. The new revenue recognition standard provides a unified model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. This guidance will be effective for the Company beginning in the first quarter of fiscal year 2018 and can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. The Company is evaluating the impact of adopting this new accounting standard on its financial statements.

In August 2014, the FASB issued new accounting guidance related to the disclosures around going concern. The new standard provides guidance around management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures. This guidance will be effective for the Company beginning in the first quarter of fiscal year 2017. Early adoption is permitted. The Company does not expect the adoption of this standard to significantly impact its financial statements.

As of September 30, 2015, the Company held 7 government and corporate debt securities with an aggregate fair value of $11.1 million that were in an unrealized loss position for less than 12 months. The gross unrealized losses of $0.006 million at September 30, 2015 represent temporary impairments on government and corporate debt securities related to multiple issuers, and were primarily caused by fluctuations in U.S. interest rates. 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; including changes in the financial condition of the security’s underlying collateral; any downgrades of the security by a rating agency; nonpayment of scheduled interest, or the reduction or elimination of dividends; as well as 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 1 and 2 years as of September 30, 2015.

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 on the basis of valuations using quoted market prices or alternate pricing sources and models utilizing market observable inputs, respectively. The Company’s money market funds were valued based on quoted prices for the specific securities in an active market and were therefore classified as Level 1. The government and corporate debt securities have been valued on the basis of valuations provided by third-party pricing services, as derived from such services’ pricing models. The pricing services may use a consensus price which is a weighted average price based on multiple sources or mathematical calculations to determine the valuation for a security, and have been classified as Level 2. The Company reviews Level 2 inputs and fair value for reasonableness and the values may be further validated by comparison to independent pricing sources. In addition, the Company reviews third-party pricing provider models, key inputs and assumptions and understands the pricing processes at its third-party providers in determining the overall reasonableness of the fair value of its Level 2 financial instruments. As of September 30, 2015 and December 31, 2014, the Company has not made any adjustments to the prices obtained from its third party pricing providers. The contingent liability is classified as Level 3 as of September 30, 2015 and December 31, 2014 and is valued using an internal rate of return model. The assumptions used in preparing the internal rate of return model include estimates for future revenues related to Physpeed products and services and a discount factor of 0.77% to 0.38% and 0.54% to 0.33% at September 30, 2015 and December 31, 2014, respectively. The assumptions used in preparing the internal rate of return model include estimates for outcome if milestone goals are achieved, the probability of achieving each outcome and discount rates. Significant changes in any of the unobservable inputs used in the fair value measurement of contingent consideration in isolation could result in a significantly lower or higher fair value. A change in estimated future revenues would be accompanied by a directionally similar change in fair value.

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, 2015

Ending balance	$	142
Net gain (loss) for the period included in earnings attributable to contingent consideration held at the end of the period:	$	(123	)

(1) In connection with the acquisition of Physpeed, the Company recorded contingent consideration based upon the expected achievement of certain 2015 and 2016 revenue milestones. Changes to the fair value of contingent consideration due to changes in assumptions used in preparing the valuation model are recorded in selling, general and administrative expense in the statement of operations.

(2) Changes to the estimated fair value of contingent consideration were primarily due to revisions to the Company's expectations of earn-out achievement.

There were no transfers between Level 1, Level 2 or Level 3 securities in the three and nine months ended September 30, 2015

Restructuring and Related Activities [Abstract]

Restructuring Activity

Restructuring Activity

In connection with the Company's acquisition of Entropic, the Company entered into a restructuring plan to address matters primarily relating to the integration of the Company and Entropic businesses. In connection with this plan, the Company terminated the employment of 73 Entropic employees during the nine months endedSeptember 30, 2015. The Company recognized associated non-recurring employee separation charges of approximately $5.7 million in the nine months endedSeptember 30, 2015 related to these terminations. Included in these employee separation charges is $1.5 million of stock compensation for accelerated stock options and RSUs vesting due to double trigger change of control agreements and other special agreements in effect with certain Entropic employees.

Additionally, in connection with the restructuring plan, the Company ceased use of the majority of Entropic's former headquarters. Accordingly, the Company recognized lease impairment charges of $1.1 million based on the adjustment to the net present value of the remaining lease obligation on the cease use date. The Company also recorded impairment charges of $3.7 million related to leasehold improvements on the unused premises.

The following table presents the activity related to the plan, which is included in restructuring charges in the unaudited consolidated statements of operations:

Income Taxes

Income Tax Disclosure [Abstract]

Income Taxes

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. The income tax provision consists primarily of income taxes related to the Company's operations in foreign jurisdictions as well as accruals for tax contingencies. 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.

As the Company does not believe that it is more-likely-than-not that it will realize a benefit from its U.S. net deferred tax assets, including its U.S. net operating losses, the Company continues to provide a full valuation allowance against those assets and therefore does not incur significant U.S. income tax expense or benefit. Additionally, the Company completed the acquisition of Entropic Communications in the second quarter of 2015. As a result of the acquisition, there was a valuation allowance release that resulted in a tax benefit of $1.6 million due to the purchase accounting adjustment for the net deferred tax liability. Furthermore, the Company does not incur expense or benefit in the certain tax free jurisdictions in which it operates.

The Company recorded a provision for income taxes of $0.5 million and a benefit of $0.6 million for the three and nine months ended September 30, 2015, respectively. The Company recorded a provision for income taxes of $0.03 million and $0.5 million for the three and nine months ended September 30, 2014, respectively. The provision (benefit) for income taxes for the three and nine months ended September 30, 2015 and 2014 primarily relates to income taxes in certain foreign jurisdictions.

During the nine months ended September 30, 2015, the Company’s unrecognized tax benefits increased by $1.9 million which includes an amount of $1.5 million related to the acquisition of Entropic. The Company does not anticipate its unrecognized tax benefits will change significantly over the next 12 months. Accrued interest and penalties associated with uncertain tax positions as of September 30, 2015 were $0.05 million and $0.02 million, respectively.

The Federal examination by the Internal Revenue Service for the years 2010 and 2011 was completed during the three months ended March 31, 2014. Any impact from the audit was included in the 2013 financial statements. The Company is not currently under examination in any other jurisdictions.

Stock-Based Compensation and Employee Benefit Plans

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 endedSeptember 30, 2015 was $10.14. The weighted-average grant date fair value per share of the RSUs and RSAs granted in the nine months endedSeptember 30, 2014 was $9.04. No stock options were granted during the nine months ended September 30, 2015.

The fair values of stock options and employee stock purchase rights (related to the Company's ESPP) were estimated at their respective grant date using the following assumptions:

Stock Options

	Nine Months Ended September 30,
	2014
Weighted-average grant date fair value per share	$	4.03
Risk-free interest rate	1.70		%
Dividend yield	—		%
Expected life (years)	4.56
Volatility	51.00		%

Employee Stock Purchase Rights

	Nine Months Ended September 30,
	2015			2014
Weighted-average grant date fair value per share	$	2.25		$	2.47
Risk-free interest rate	0.09		%	0.05		%
Dividend yield	—		%	—		%
Expected life (years)	0.50			0.50
Volatility	32.65		%	47.75		%

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 historical data due to the Company’s limited number of stock option exercises under the 2010 Equity Incentive Plan. 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. Effective for the nine months ended September 30, 2014, the Company is no longer incorporating the historical volatility of comparable companies in determining estimated volatility.

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

	Three Months Ended September 30,				Nine Months Ended September 30,
	2015		2014		2015		2014
Cost of net revenue	$	73	$	35	$	169	$	96
Research and development	3,496		2,574		8,889		7,152
Selling, general and administrative	1,442		1,393		4,466		3,832
	$	5,011	$	4,002	$	13,524	$	11,080

In connection with the acquisition of Entropic, the Company assumed stock options and RSUs originally granted by Entropic. Stock-based compensation expense in the three and nine months ended September 30, 2015 included $0.8 million and $3.2 million, respectively, related to assumed Entropic stock options and RSUs.

In the nine months ended September 30, 2015, the Company granted 1.1 million RSUs with a fair value of $11.2 million related to its annual equity compensation review program, which will be expensed over the next four years. In the nine months ended September 30, 2014, the Company granted 0.7 million RSUs with a fair value of $6.4 million and 0.4 million stock options with a fair value of $1.7 million related to its annual equity compensation review program, which are expensed over the next four years.

Employee Benefit Plans

At September 30, 2015, the Company had stock-based compensation awards outstanding under the following plans: the 2004 Stock Plan, the 2010 Equity Incentive Plan and the 2010 Employee Stock Purchase Plan as well as the following former Entropic plans: the RF Magic 2000 Incentive Stock Plan, the 2001 Stock Option Plan, the 2007 Equity Incentive Plan, the 2007 Non-Employee Director's Plan and the 2012 Inducement Award Plan. All current stock awards are issued under the 2010 Equity Incentive Plan and 2010 Employee Stock Purchase Plan.

2010 Equity Incentive Plan

The 2010 Equity Incentive 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, 2015, 1.5 million shares of Class A common stock were automatically added to the shares authorized for issuance under the 2010 Equity Incentive Plan pursuant to an “evergreen” provision contained in the 2010 Equity Incentive 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 Class A 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, 2015, 0.5 million 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.

Executive Incentive Bonus Plan

In April 2012, the Company's compensation committee amended its Executive Incentive Bonus Plan to, among other things, permit the settlement of awards under the plan in the form of shares of its Class A common stock. In May 2013, the Company's compensation committee amended its Executive Incentive Bonus Plan to permit the settlement of awards under the plan in any combination of cash or shares of its Class A common stock. For the January 1, 2015 to June 30, 2015, 2014 and 2013 performance period, actual awards under the Executive Incentive Bonus Plan were settled in Class A common stock issued under its 2010 Equity Incentive Plan with the number of shares issuable to plan participants determined based on the closing sales price of the Company's Class A common stock as determined in trading on the New York Stock Exchange on August 20, 2015, May 14, 2015 and May 9, 2014, respectively. Additionally, the Company settled all bonus awards for all other employees for the January 1, 2015 to June 30, 2015, 2014 and 2013 performance period in shares of its Class A common stock. The Company issued 0.3 million shares of its Class A common stock for the January 1, 2015 to June 30, 2015 performance period upon settlement of the bonus awards on August 20, 2015. The Company issued 0.2 million shares of its Class A common stock for the 2014 performance period upon settlement of the bonus awards on May 14, 2015. The Company issued 0.6 million shares of its Class A common stock for the 2013 performance period upon settlement of the bonus awards on May 9, 2014.

Common Stock

At September 30, 2015, 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.

Acquisition of Entropic Communications, Inc.

On April 30, 2015, the Company completed its acquisition of Entropic Communications, Inc. ("Entropic"). Pursuant to the terms of the merger agreement dated as of February 3, 2015, by and among the Company, Entropic, and two wholly-owned subsidiaries of the Company ("the Merger Agreement"), all of the Entropic outstanding shares were converted into the right to receive consideration consisting of cash and shares of the Company’s Class A common stock. The Company paid an aggregate of $111.1 million and issued an aggregate of 20.4 million shares of the Company’s Class A common stock, to the stockholders of Entropic. In addition, the Company assumed all outstanding Entropic stock options and unvested restricted stock units that were held by continuing service providers (as defined in the Merger Agreement). The Company used Entropic’s cash and cash equivalents to fund a significant portion of the cash portion of the merger consideration and, to a lesser extent, its own cash and cash equivalents.

As a result of the acquisition, the Company expects to benefit from the economies of scale across engineering and supply chain operations, as well as from elimination of redundancy across engineering, sales, and general and administrative functions. Entropic has been recognized for pioneering the MoCA® (Multimedia over Coax Alliance) home networking standard and inventing Direct Broadcast Satellite outdoor unit (“DBS ODU”) solutions which consist of band translation switch ("BTS") and channel stacking switch ("CSS") products which simplify the installation required to support simultaneous reception of multiple channels from multiple satellites over a single cable. Entropic has a rich history of innovation and deep expertise in RF, analog/mixed signal and digital signal processing technologies. Entropic’s silicon solutions have been broadly deployed across major cable, satellite, and fiber service providers. The Company expects the acquisition of Entropic to add significant scale to the Company's analog/mixed-signal business, expand the Company’s addressable market and enhance the strategic value of the Company’s offerings to broadband and access partners, OEM customers, and service providers.

The merger has been accounted for under the acquisition method of accounting in accordance with ASC 805, Business Combinations, with MaxLinear treated as the accounting acquirer. Under this method of accounting, the Company recorded the acquisition based on the fair value of the consideration given and the cash consideration paid. The Company allocated the acquisition consideration paid to the identifiable assets acquired and liabilities assumed based on their respective preliminary fair values at the date of completion of the merger. Any excess of the value of consideration paid over the aggregate fair value of those net assets has been recorded as goodwill.

The total consideration for the Entropic acquisition of $289.4 million is comprised of the equity value of shares of the Company's common stock that were issued in the transaction of $173.8 million, the portion of outstanding equity awards deemed to have been earned as of April 30, 2015 of $4.5 million and cash of $111.1 million. The portion of outstanding equity awards deemed not to have been earned of $9.3 million as of April 30, 2015 will be expensed over the remaining future vesting period, including $0.8 million and $3.2 million for the three months and nine months ended September 30, 2015. Assumed equity awards consisted of 1.9 million of the Company's stock options and 1.3 million restricted stock units.

The Company capitalized $0.7 million of costs related to the registration and issuance of the 20.4 million shares of the Company’s Class A common stock to Entropic’s stockholders upon completion of the merger. In addition, the Company registered an additional 3.2 million shares related to shares of the Company’s Class A common stock which may be issued pursuant to outstanding equity awards under the former Entropic Stock Plans.

The estimated fair value of the purchase price consideration consisted of the following:

Cash	$	111,125
Class A common stock issued	173,781
Equity awards assumed	4,485
Total purchase consideration	$	289,391

Pursuant to the Company's business combinations accounting policy, the Company estimated the preliminary fair values of net tangible and intangible assets acquired and the excess of the consideration transferred over the aggregate of such fair values was recorded as goodwill. The preliminary fair values of net tangible assets and intangible assets acquired were based upon preliminary valuations and the Company's estimates and assumptions are subject to change within the measurement period (up to one year from the acquisition date). The primary areas that remain preliminary relate to the fair values of liabilities acquired, certain legal matters, income and non-income based taxes and residual goodwill. The Company expects to continue to obtain information to assist in determining the fair values of the net assets acquired during the measurement period.

The following table summarizes the preliminary allocation of the assets acquired and liabilities assumed at the acquisition date:

	Fair Value
Cash, cash equivalents and short-term investments	$	107,510
Accounts receivable	29,214
Inventory	29,582
Prepaid expenses	5,680
Property and equipment, net	18,914
Other long-term assets	2,419
Intangible assets	92,400
Accounts payable	(17,552		)
Accrued price protection liability	(3,486		)
Accrued expenses and other current liabilities	(10,855		)
Accrued compensation	(3,517		)
Deferred tax liability	(1,592		)
Other long-term liabilities	(7,498		)
Total identifiable net assets	241,219
Goodwill	48,172
Fair value of net assets acquired	$	289,391

In connection with the acquisition of Entropic, the Company has assumed liabilities related to Entropic product quality issues, warranty claims and contract obligations which are included in accrued expenses and other current liabilities in the purchase price allocation above.

The fair value of inventories acquired included an acquisition accounting fair market value step-up of $14.2 million, which was fully amortized as of September 30, 2015. During the three and nine months ended September 30, 2015, the Company recognized $0.9 million and $14.2 million, respectively, as a component of cost of sales as the inventory acquired on April 30, 2015 was sold to the Company’s customers.

During the three months ended September 30, 2015, the Company recorded a net $0.5 million adjustment to goodwill primarily due to a $0.4 million increase related to product settlements, $0.3 million increase related to foreign taxes payables and a return to provision true-up, offset by $0.2 million decrease related to valuation allowance adjustment to deferred tax liability.

The Company is subject to legal and regulatory requirements, including but not limited to those related to taxation in each of the jurisdictions in the countries in which it operates. The Company has conducted a preliminary assessment of liabilities arising from these tax matters in each of these jurisdictions, and has recognized provisional amounts in its initial accounting for the acquisition of Entropic for the identified liabilities. However, the Company is continuing its procedures to identify information pertaining to these matters as well as other legal and regulatory matters during the measurement period. The Company has not obtained all necessary information to finalize its provisional amounts pertaining to income taxes and loss contingencies associated with legal and regulatory matters.  If new information is obtained about facts and circumstances that existed at the acquisition date, the Company will either adjust its measurement of provisional amounts or recognize and measure liabilities not previously identified. 

Acquisition and integration-related costs of $5.3 million were included in selling, general, and administrative expenses in the Company's statement of operations for the nine months ended September 30, 2015.

The following table presents details of the preliminary identified intangible assets acquired through the acquisition of Entropic:

	Estimated Useful Life (in years)	Fair Value
Developed technology	7.0	$	43,600
In-process research and development	n/a	18,200
Trademarks and trade names	7.0	1,700
Customer relationships	5.0	4,700
Backlog	0.7	24,200
Total intangible assets		$	92,400

The fair value of the $92.4 million of identified intangible assets acquired in connection with the Entropic acquisition was estimated using an income approach. Under the income approach, an intangible asset's fair value is equal to the present value of future economic benefits to be derived from ownership of the asset. Indications of value are developed by discounting future net cash flows to their present value at market-based rates of return. More specifically, the fair value of the developed technology, IPR&D and backlog assets was determined using the multi-period excess earnings method, or MPEEM. MPEEM is an income approach to fair value measurement attributable to a specific intangible asset being valued from the asset grouping’s overall cash-flow stream. MPEEM isolates the expected future discounted cash-flow stream to its net present value. Significant factors considered in the calculation of the developed technology and IPR&D intangible assets were the risks inherent in the development process, including the likelihood of achieving technological success and market acceptance. Each project was analyzed to determine the unique technological innovations, the existence and reliance on core technology, the existence of any alternative future use or current technological feasibility and the complexity, cost, and time to complete the remaining development. Future cash flows for each project were estimated based on forecasted revenue and costs, taking into account the expected product life cycles, market penetration, and growth rates. Developed technology will begin amortization immediately and IPR&D will begin amortization upon the completion of each project. If any of the projects are abandoned, the Company will be required to impair the related IPR&D asset.

In connection with the Company’s acquisition of Entropic and to address issues primarily relating to the integration of the Company and Entropic businesses, the Company entered into a restructuring plan. See Note 4.

The following unaudited pro forma financial information presents the combined results of operations for each of the periods presented, as if the acquisition had occurred at the beginning of fiscal year 2014:

The unaudited pro forma financial information does not reflect any operating efficiencies and cost saving that may be realized from the integration of the acquisition in the Company's unaudited consolidated statements of operations.

For the three months ended September 30, 2015, $54.5 million of revenue and $27.0 million of gross profit of former Entropic operations since the acquisition date are included in the Company's unaudited consolidated statements of operations.

Acquisition of Physpeed, Co., Ltd.

On October 31, 2014, the Company acquired 100% of the outstanding common shares of Physpeed Co., Ltd. (“Physpeed”), a privately held developer of high-speed physical layer interconnect products addressing enterprise and telecommunications infrastructure market applications. The Company paid $9.3 million in cash in exchange for all outstanding shares of capital stock and equity of Physpeed. $1.1 million of the consideration payable to the former shareholders of Physpeed was placed into escrow pursuant to the terms of the definitive merger agreement. The escrow release date is twelve months following the closing date of October 31, 2014 and expected to be paid out after October 31,2015. In addition, the definitive merger agreement provided for potential consideration of $1.7 million of held back merger proceeds for the former principal shareholders of Physpeed which will be paid over a two year period contingent upon continued employment and potential earn-out consideration of up to $0.75 million to the former shareholders of Physpeed for the achievement of certain 2015 and 2016 revenue milestones. As of September 30, 2015, $0.8 million of held back merger proceeds have been paid. The Company had also entered into retention and performance-based agreements with Physpeed employees for up to $3.25 million to be paid in cash or shares of MaxLinear Class A common stock based on the achievement of certain 2015 and 2016 revenue milestones.

As a result of the acquisition, the Company expects to reduce costs through economies of scale. The acquisition of Physpeed significantly accelerates the Company's total addressable market expansion efforts into infrastructure for data center, as well as metro and long-haul telecommunications operators. Physpeed’s expertise in high-speed analog design, combined with the Company's proven low-power digital CMOS mixed signal-integration and DSP capabilities, is expected to bring to market solutions that will uniquely enable the data traffic growth generated from smartphones and tablets, and over-the-top, or OTT, streaming video, in addition to cloud computing and data analytics in hyper-scale data centers. The goodwill of $1.2 million arising from the acquisition consists largely of the synergies and economies of scale expected from combining the operations of the Company and Physpeed. None of the goodwill recognized is expected to be deductible for income tax purposes.

In accordance with accounting principles generally accepted in the United States, the Company accounted for the merger using the acquisition method of accounting for business combinations. Under this method of accounting, the Company recorded the acquisition based on the fair value of the consideration given and the cash consideration paid in the merger at the time of the merger. The Company allocated the purchase price to the identifiable assets acquired and liabilities assumed based on their respective fair values at the date of the completion of the merger. Any excess of the value of consideration paid over the aggregate fair value of those net assets has been recorded as goodwill.

The following table summarizes the consideration paid for Physpeed:

Cash	$	9,250
Contingent consideration	265
Fair value of total consideration transferred	$	9,515

The following table summarizes the fair values of the assets acquired and liabilities assumed at the acquisition date. The Company completed the purchase price allocation for its acquisition of Physpeed as of December 31, 2014:

Financial assets	$	114
Accounts receivable	447
Prepaid expenses	28
Inventory	69
Fixed assets	56
Identifiable intangible assets	10,000
Financial liabilities	(65		)
Net deferred tax liability	(2,335		)
Total identifiable net assets	8,314
Goodwill	1,201
	$	9,515

Acquisition-related costs of $0.3 million were included in selling, general, and administrative expenses in the Company's statement of operations for the year ended December 31, 2014.

The fair value of the acquired identifiable intangible assets of $10.0 million consists of developed technology of $2.7 million and IPR&D of $7.3 million. Both the developed technology and IPR&D are related to optical interconnect interface physical layers products and the estimated useful lives have been assessed to be seven years for the developed technology. Developed technology will be amortized immediately and IPR&D will begin amortization upon the completion of each project. If any of the projects are abandoned, the Company will be required to impair the related IPR&D asset. The fair value of the developed technology and IPR&D was determined using the multi-period excess earnings method, or MPEEM. MPEEM is an income approach to fair value measurement attributable to a specific intangible asset being valued from the asset grouping’s overall cash-flow stream. MPEEM isolates the expected future discounted cash-flow stream to their net present value. Significant factors considered in the calculation were the risks inherent in the development process, including the likelihood of achieving technological success and market acceptance. Each project was analyzed to determine the unique technological innovations, the existence and reliance on core technology, the existence of any alternative future use or current technological feasibility and the complexity, cost, and time to complete the remaining development. Future cash flows for each project were estimated based on forecasted revenue and costs, taking into account the expected product life cycles, market penetration, and growth rates.

Compensation Arrangements

In connection with the acquisition of Physpeed, the Company has agreed to pay additional consideration in future periods. There was a holdback of the merger proceeds whereby the former principal shareholders of Physpeed will be paid a quarterly amount of $0.2 million beginning on January 31, 2015 and ending on October 31, 2016 for a total of $1.7 million. Certain employees of Physpeed will be paid a total of $0.1 million of which $0.07 million will be paid in 2015 and $0.05 million will be paid in 2016. These payments are accounted for as transactions separate from the business combination as the payments are contingent upon continued employment and will be recorded as post-combination compensation expense in the Company's financial statements during the service period. The Company also agreed to a working capital adjustment of $0.04 million that was settled by December 31, 2014.

Earn-Out

The contingent earn-out consideration had an estimated fair value of $0.3 million at the date of acquisition. The earn-out is payable up to $0.75 million to the former shareholders of Physpeed. The 2015 earn-out is based on $0.375 million multiplied by the 2015 revenue percentage as defined in the definitive merger agreement. The 2016 earn-out is based on $0.375 million multiplied by the 2016 revenue percentage as defined in the definitive merger agreement. Subsequent changes to the fair value will be recorded through earnings. The fair value of the earn-out was $0.1 million and $0.3 million at September 30, 2015 and December 31, 2014, respectively. The change in the fair value of the earn-out was primarily due to revisions to the Company's expectations of earn-out achievement.

RSU Awards

The Company will grant restricted stock units, or RSUs, under its equity incentive plan to Physpeed continuing employees if certain 2015 and 2016 revenue targets are met contingent upon continued employment. The total maximum amounts of these RSUs are $3.25 million. These participants will be eligible to receive $1.625 million of the RSUs in 2015 and $1.625 million in 2016.

The 2015 performance grant, if any earned, will be based on the calculation of the 2015 maximum revenue RSU amount multiplied by the 2015 revenue percentage as defined in the definitive merger agreement. The 2015 maximum revenue RSU amount is 50% of the aggregate maximum RSU award value divided by the 2015 average company share price (the average closing sales prices of stock trading on the New York Stock exchange over five consecutive trading days ending on the trade date that is the third trading date prior to the 2015 determination date (no later than ten business days after filing the Form 10-K for the 2015 fiscal year)). Qualifying revenues are the net revenues recognized in the 2015 fiscal year directly attributable to sales of Physpeed products or the Company’s provision of non-recurring engineering services exclusively with respect to the Physpeed products in accordance with U.S. GAAP reflected in the Company’s audited financial statements.

The 2016 performance grant, if any earned, will be based on the calculation of the 2016 maximum revenue RSU amount multiplied by the 2016 revenue percentage as defined in the definitive merger agreement. The 2016 maximum revenue RSU amount is 50% of the aggregate maximum RSU award value divided by the 2016 average company share price (the average closing sales prices of stock trading on the New York Stock exchange over five consecutive trading days ending on the trade date that is the third trading date prior to the 2016 determination date (no later than ten business days after filing the Form 10-K for the 2016 fiscal year). Qualifying revenues are the net revenues recognized in the 2016 fiscal year directly attributable to sales of Physpeed products or the Company’s provision of non-recurring engineering services exclusively with respect to the Physpeed products in accordance with U.S. GAAP reflected in the Company’s audited financial statements.

The Company will record compensation expense for the 2015 RSUs over a 14 month service period from October 31, 2014 through December 31, 2015. The Company will record compensation expense for the 2016 RSUs over a 26 month service period from October 31, 2014 through December 31, 2016. The Company has recorded an accrual for the stock-based compensation expense for the 2015 and 2016 RSUs of $0.7 million at September 30, 2015.
