1. Organization and Summary of Significant Accounting Policies

Description of Business

MaxLinear, Inc. was incorporated in Delaware in September 2003. MaxLinear, Inc., together with its wholly owned subsidiaries, collectively referred to as MaxLinear, or the Company, is a provider of radio-frequency, or RF, high-performance analog, and mixed-signal communications system-on-chip solutions for the connected home, wired and wireless infrastructure, and industrial and multi-market applications. MaxLinear's customers include electronics distributors, 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 DOCSIS broadband modems and gateways, wireline connectivity devices for in-home networking applications, RF transceivers and modems for wireless carrier access and backhaul infrastructure, fiber-optic modules for data center, metro, and long-haul transport networks, video set-top boxes and gateways, hybrid analog and digital televisions, direct broadcast satellite outdoor and indoor units, and power management and interface products used in these and a range of other markets. The Company is a fabless integrated circuit design company whose products integrate all or a substantial portion of a broadband communication system.

Basis of Presentation and Principles of Consolidation

The accompanying unaudited consolidated financial statements include the accounts of MaxLinear, Inc. and its wholly owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP, 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 GAAP for complete financial statements. All intercompany transactions and investments have been eliminated in consolidation. In the opinion of management, the Company’s unaudited consolidated interim financial statements contain adjustments, including normal recurring accruals necessary to present fairly the Company’s consolidated financial position, results of operations, comprehensive income (loss) and cash flows.

The consolidated balance sheet as of December 31, 2017 was derived from the Company’s audited consolidated financial statements at that date. The accompanying unaudited consolidated interim financial statements should be read in conjunction with the audited consolidated financial statements and related notes thereto for the year ended December 31, 2017 included in the Company’s Annual Report on Form 10-K filed by the Company with the Securities and Exchange Commission, or the SEC, on February 20, 2018, or the Annual Report. Interim results for the three and nine months ended September 30, 2018 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2018.

Use of Estimates

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

Summary of Significant Accounting Policies

Refer to the Company’s Annual Report for a summary of significant accounting policies. On January 1, 2018, the Company adopted Financial Accounting Standards Board, or FASB, Accounting Standards Codification Topic 606, Revenue from Contracts with Customers, or ASC 606, and accordingly, modified its policy on revenue recognition as stated below. The primary impact of adopting ASC 606 for the Company was to accelerate the timing of the Company’s revenue and related cost recognition on products sold via some of its distributors, which changed from recognition upon the sale to the distributors' end customers, or the sell-through method, to recognition upon the Company's sale to the distributor, or the sell-in method. The Company is now also required to estimate the effects of pricing credits to its distributors from contractual price protection and unit rebate provisions, as well as stock rotation rights and record such estimated credits upon the Company's sale to the distributor.

There have been no other material changes to our significant accounting policies during the nine months endedSeptember 30, 2018.

Revenue Recognition

Substantially all of the Company's revenue is generated from sales of the Company’s integrated circuits to electronics distributors, module makers, OEMs, and ODMs under individual customer purchase orders, some of which have underlying master sales agreements that specify terms governing the product sales. Effective January 1, 2018, the Company adopted ASC 606 and recognizes revenue at the point in time when control of the products is transferred to the customer at the estimated net consideration for which collection is probable, taking into account the customer's rights to price protection, other pricing credits, unit rebates, and rights to return unsold product. Transfer of control occurs either when products are shipped to or received by the distributor or direct customer, based on the terms of the specific agreement with the customer, if the Company has a present right to payment and transfer of legal title and the risks and rewards of ownership to the customer has occurred. For most of the Company's product sales, transfer of control occurs upon shipment to the distributor or direct customer. In assessing whether collection of consideration from a customer is probable, the Company considers the customer's ability and intention to pay that amount of consideration when it is due. Payment of invoices is due as specified in the underlying customer agreement, typically 30 days from the invoice date, which occurs on the date of transfer of control of the products to the customer. Since payment terms are less than a year, the Company has elected the practical expedient and does not assess whether a customer contract has a significant financing component.

A five-step approach is applied in the recognition of revenue under ASC 606: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when the Company satisfies a performance obligation. The Company applied ASC 606 to its customer contracts that were not completed before the January 1, 2018 adoption date. Customer purchase orders plus the underlying master sales agreements are considered to be contracts with the customer for purposes of applying the five-step approach under ASC 606.

Pricing adjustments and estimates of returns under contractual stock rotation rights are treated as variable consideration for purposes of determining the transaction price, and are estimated at the time control transfers using the expected value method based on the Company's analysis of actual price adjustment claims by distributors and historical product return rates, and then reassessed at the end of each reporting period. The Company also considers whether any variable consideration is constrained, since such amounts for which it is probable that a significant reversal will occur when the contingency is subsequently resolved are required to be excluded from revenues. Price adjustments are finalized at the time the products are sold through to the end customer and the distributor or end customer submits a claim to reduce the sale price to a pre-approved net price. Stock rotation allowances are capped at a fixed percentage of the Company's sales to a distributor for a period of time, up to six months, as specified in the individual distributor contract. If the Company's current estimates of such credits and rights are materially inaccurate, it may result in adjustments that affect future revenues and gross profits. Returns under the Company's general assurance warranty of products for a period of one to three years have not been material and warranty-related services are not considered a separate performance obligation under the customer contracts. Most of the Company's customers resell our product as part of their product and thus are tax-exempt; however, to the extent the Company collects and remits taxes on product sales from customers, it has elected to exclude from the measurement of transaction price such taxes.

Each distinct promise to transfer products is considered to be an identified performance obligation for which revenue is recognized upon transfer of control of the products to the customer. Although customers may place orders for products to be delivered on multiple dates that may be in different quarterly reporting periods, all of the orders are scheduled within 1 year from the order date. The Company has opted to not disclose the portion of revenues allocated to partially unsatisfied performance obligations, which represent products to be shipped within 12 months under open customer purchase orders, at the end of the current reporting period as allowed under ASC 606. The Company has also elected to record sales commissions when incurred, pursuant to the practical expedient under ASC 340, as the period over which the sales commission asset that would have been recognized is less than one year.

Customer contract liabilities consist of obligations to deliver rebates to customers in the form of units of products which are included in accrued expenses and other current liabilities in the consolidated balance sheets. Other obligations to customers consist of estimates of price protection rights offered to the Company's end customers, which are included in accrued price protection liability in the consolidated balance sheets, as well as price adjustments expected to be claimed by the distributor upon sell-through of the products to their customers, and amounts expected to be returned by distributors under stock rotation rights, which are included in accrued expenses and other current liabilities in the consolidated balance sheets. The Company also records a right of return asset, consisting of amounts representing the products the Company expects to receive from customers in returns, which is included in inventory in the consolidated balance sheets, and is typically settled within six months of transfer of control to the customer, or the period over which stock rotation rights are based. Upon lapse of the time

period for stock rotations, or the contractual end to price protection and rebate programs, which is approximately one to two years, and when the Company believes unclaimed amounts are no longer subject to payment and will not be paid, any remaining asset or liability is derecognized by an offsetting entry to cost of net revenue and net revenue. For additional disclosures regarding contract liabilities and other obligations to customers, see Note 12.

The Company assesses customer accounts receivable and contract assets for impairment in accordance with ASC 310-10-35.

The impacts of adopting ASC 606 as shown above were primarily related to the acceleration of the timing of the Company’s revenue and related cost recognition on products sold via some of its distributors, which changed from sale to the distributors' end customers, or the sell-through method, to recognition upon the Company's sale to the distributor, or the sell-in method.

Revenues from sales through the Company’s distributors accounted for 46% and 41% of net revenue for the three months ended September 30, 2018 and 2017, respectively. Revenues from sales through the Company’s distributors accounted for 41% and 31% of net revenue for the nine months ended September 30, 2018 and 2017, respectively.

Recently Adopted Accounting Pronouncements

In May 2014, the FASB, issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which provides for new accounting guidance related to revenue recognition. This new standard replaced all prior U.S. GAAP guidance on this topic and eliminated 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 became effective for the Company on January 1, 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 applied the guidance prospectively with an adjustment to accumulated deficit for the cumulative effect of adoption. Adoption of the amendments in this guidance accelerated the timing of the Company’s revenue and related cost recognition on products sold via some distributors, which changed from the sell-through method to the sell-in method under this guidance. The Company is also required to estimate the effects of pricing credits to its distributors from contractual price protection and unit rebate provisions, as well as stock rotation rights. The Company has performed an assessment of the impact of adopting this new accounting standard on its consolidated financial position and results of operations. The impact of adoption of this new accounting standard for the year ending December 31, 2018 will vary depending on the level of inventory remaining at December 31, 2018 at distributors for which the Company previously recognized revenue on a sell-through basis, and therefore could have a material impact on the Company's revenues for the year ending December 31, 2018. The impact to accumulated deficit as of January 1, 2018 was not material. As a result of applying the guidance prospectively with an adjustment to accumulated deficit in the Company's consolidated financial statements for the cumulative effect of adoption, revenues that would have been recognized on a sell-through basis for the amount of deferred revenue and profit remaining as of the adoption date will not be recognized in earnings for any period.

In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this update include, among other things, a requirement to (1) measure equity investments (except equity method investments) at fair value with changes in fair value recognized in net income, with an option to measure equity investments that do not have readily determinable fair values at cost minus any impairment plus or minus any changes resulting from observable price changes; previously changes in fair value were recognized in other comprehensive income, and (2) separately present financial assets and liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statement. The amendments in this update were effective for the Company beginning in the first quarter of fiscal year 2018. The adoption of the amendments in this update did not have a material impact on the Company's consolidated financial position and results of operations for the three and nine months ended September 30, 2018.

In March 2016, the FASB issued ASU No. 2016-08, Principal versus Agent Considerations (Reporting Revenue Gross versus Net) to clarify the revenue recognition implementation guidance on principal versus agent considerations. The amendments in this update clarify that when another party is involved in providing goods or services to a customer, an entity that is the principal has obtained control of a good or service before it is transferred to a customer, and provides indicators to assist an entity in determining whether it controls a specified good or service prior to the transfer to the customer. An entity that is the principal recognizes revenue in the gross amount of consideration to which it expects to be entitled in exchange for the specified good or service transferred to the customer, whereas an agent recognizes revenue in the amount of any fee or commission to which it expects to be entitled in exchange for arranging for the specified good or service to be provided by the other party. The amendments in this update were effective for the Company beginning in the first quarter of fiscal year 2018, concurrent with and applied on the same basis as the new revenue recognition standard. The adoption of the amendments in this update did not have a material impact on the Company's consolidated financial position and results of operations for the three and nine months ended September 30, 2018.

In August 2016, the FASB issued ASU No. 2016-15, Classification of Certain Cash Receipts and Cash Payments to eliminate the diversity in practice regarding the presentation and classification of certain cash receipts and cash payments, including, among other things, contingent consideration payments made following a business combination, proceeds from the settlement of insurance claims in the statement of cash flows, and debt prepayment or debt extinguishment costs. Cash payments not made soon after the acquisition date up to the amount of the contingent consideration liability recognized at the acquisition date should be classified as financing activities and any excess payments should be classified as operating activities, whereas cash payments made soon after the acquisition date to settle the contingent consideration should be classified as investing activities and cash payments for debt prepayment or debt extinguishment costs should be classified as financing activities. Cash proceeds received from settlement of insurance claims should be classified on the basis of the nature of the related losses. The amendments in this update should be applied using a retrospective transition method to each period

presented, unless impracticable, and if impracticable, would be applied prospectively as of the earliest date practicable. The amendments in this update were effective for the Company beginning in the first quarter of fiscal year 2018. The adoption of the amendments in this update did not have a material impact on the Company's consolidated statements of cash flows for the three and nine months ended September 30, 2018.

In May 2017, the FASB issued ASU No. 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting to provide clarity and reduce both (1) diversity in practice and (2) cost and complexity when applying the guidance in Topic 718, Compensation—Stock Compensation, to a change to the terms or conditions of a share-based payment award. The amendments in this update require the Company to account for the effects of a modification in a stock-based award unless the fair value, vesting conditions and classification of the modified award is the same as those of the original award immediately before the original award is modified. If the modification does not affect any of the inputs to the valuation technique that the entity uses to value the award, the entity is not required to estimate the value immediately before and after the modification. The amendments in this update were effective for the Company for fiscal years beginning with fiscal year 2018, including interim periods within those years, with early adoption permitted in any interim period. The amendments in this update are applied prospectively to an award modified on or after the adoption date. Since the Company has not had any modifications to stock-based awards that do not affect the inputs into the Black Scholes fair value calculation, the adoption of this guidance did not have a material impact on the Company's consolidated financial position and results of operations for the three and nine months ended September 30, 2018.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act, or the Tax Act. The Tax Act makes broad and complex changes to the U.S. tax code. On December 22, 2017, the U.S. Securities and Exchange Commission Staff, or SEC Staff, issued guidance in Staff Accounting Bulletin No. 118, or SAB 118, to address certain fact patterns where the accounting for changes in tax laws or tax rates under ASC Topic 740 is incomplete upon issuance of an entity's financial statements for the reporting period in which the Tax Act is enacted. As permitted in SAB 118, in 2017, the Company took a measurement period approach and reported certain provisional amounts, based on reasonable estimates, for certain tax effects in which the accounting under ASC 740 is incomplete. Such provisional amounts are subject to adjustment during a limited measurement period, not to extend one year beyond the tax law enactment date, until the accounting under ASC 740 is complete. The Company also made required supplemental disclosures in the notes to the 2017 consolidated financial statements to accompany the provisional amounts, including the reasons for the incomplete accounting, the additional information or analysis that is needed, and other information relevant to why the Company was not able to complete the accounting required under ASC 740 in a timely manner. For adjustments to previously reported provisional amounts made in the three and nine months ended September 30, 2018, refer to Note 10. Additional adjustments to such reported provisional amounts could result in a material adverse impact to the Company's consolidated financial position and results of operations in 2018.

In February 2018, the FASB issued ASU No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The amendments in this update allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Act. The amendments in this update are effective for the Company beginning in fiscal 2019, including interim periods. Early adoption is permitted. The amendments should be applied either in the period of adoption or retrospectively to each period or periods in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Act is recognized. The Company elected to early adopt this guidance in the three months ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's consolidated financial position and results of operations for the three and nine months ended September 30, 2018.

In March 2018, the FASB issued ASU No. 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118. The amendments in this update amend the SEC paragraphs included in Topic 740 to be consistent with the guidance in SAB 118, which the Company adopted in the three months ended December 31, 2017, as described above.

In June 2018, the FASB issued ASU No. 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, to expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. As a result, the accounting for share-based payment awards to nonemployees and employees will be substantially aligned by eliminating the need to measure nonemployee share-based awards at fair value on the earlier of performance commitment date or date performance is complete. Both employee and nonemployee share-based awards are now measured at grant-date fair value. The amendments in this update are effective for the Company beginning with fiscal year 2019, including interim periods, with early adoption permitted, but no earlier than the

12

Table of Contents MAXLINEAR, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

Company's adoption of Topic 606. The Company elected to early adopt the amendments in this update as of July 1, 2018, with the cumulative effect of the change recorded against accumulated deficit as of July 1, 2018. As the Company's nonemployee share-based awards are not significant, such adoption did not have a material impact on the Company's consolidated accumulated deficit as of July 1, 2018.

Recently Issued Accounting Pronouncements

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The amendments in this update require a lessee to recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term for all leases with terms greater than twelve months. For leases less than twelve months, an entity is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognize lease expense for such leases generally on a straight-line basis over the lease term. The Company intends to make this election. Also, in July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements, to provide an additional transition method. An entity can now elect not to present comparative financial information under Topic 842 if it recognizes a cumulative-effect adjustment to retained earnings upon adoption. The Company also intends to make this election. The amendments in these update are effective for the Company for fiscal years beginning with fiscal year 2019, including interim periods within those years, with early adoption permitted. The Company has performed a preliminary assessment of the impact of the adoption of the amendments in these updates on the Company's consolidated financial position and results of operations for the Company's leases, which primarily consist of facility leases. Based on that assessment, the Company has determined that the right-of-use asset and lease liability, which is measured at the present value of future lease payments, are expected to have a material impact on the Company's consolidated financial position. In addition, through the adoption date, the Company will complete its inventory of its leases and finalize its assessment of the impact of the adoption of Topic 842.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, to simplify the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. An entity no longer will determine goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if the reporting unit had been acquired in a business combination. Instead, under the amendments in this update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. The Board also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. The amendments in this update are effective for the Company beginning with fiscal year 2020, including interim periods, with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of the amendments in this update is not expected to have a material impact on the Company's consolidated financial position and results of operations.

In July 2018, the FASB issued ASU No. 2018-09, Codification Improvements, to clarify the Codification and prevent unintended application of the guidance. An amendment to ASC 718-740, Compensation—Stock Compensation—Income Taxes, clarifies that excess tax benefits should be recognized in the period in which the amount of the deduction is determined. The transition and effective date guidance is based on the facts and circumstances of each amendment. The amendment identified above will be effective for the Company beginning with fiscal year 2019. The adoption of the amendments in this update is not expected to have a material impact on the Company's consolidated financial position and results of operations.

In July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842, Leases, to clarify on how to apply certain aspects of the new lease accounting standard. The amendments in this update, among other things, better articulates the requirement for a lessee's reassessment of lease classification as of the effective date of a modification, clarifies that a change to an index or rate for variable lease payments does not constitute a resolution of a contingency that would result in the remeasurement of lease payments, and requires entities that apply Topic 842 retrospectively to each reporting period and do not adopt the practical expedients to write off any prior unamortized initial direct costs that do not meet the definition under Topic 842 to equity. The amendments in this update have the same effective date and transition requirements as the new lease standard summarized above. The Company is currently in the process of evaluating the impact of adoption of Topic 842 on the Company’s consolidated financial position and results of operations as stated above.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework— Changes to the Disclosure Requirements for Fair Value Measurement,to improve the fair value measurement reporting of financial instruments. The amendments in this update require, among other things, added disclosure of the range and weighted

13

Table of Contents MAXLINEAR, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

average of significant unobservable inputs used to develop Level 3 fair value measurements. The amendments in this update eliminate, among other things, disclosure of the reasons for and amounts of transfers between Level 1 and Level 2 for assets and liabilities that are measured at fair value on a recurring basis and an entity's valuation processes for Level 3 fair value measurements. The amendments in this update will be effective for the Company beginning with fiscal year 2020, with early adoption permitted. Retrospective application is required for all amendments in this update except the added disclosures, which should be applied prospectively. The adoption of the amendments in this update is not expected to have a material impact on the Company's consolidated financial position and results of operations.

In August 2018, the FASB issued ASU No. 2018-15, Intangibles- Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract, to provide additional guidance on the accounting for costs of implementing cloud computing arrangements that are service contracts. The amendments in this update require the capitalization of implementation costs during the application development stage of such hosting arrangements and amortization of the expense over the term of the arrangement including any option to extend reasonably certain to be exercised or option to terminate reasonably certain not to be exercised. Capitalized implementation costs and amortization thereof are also required to be classified in the same line item in the statements of financial position, operations and cash flows associated with the hosting service fees. The amendments in this update will be effective for the Company beginning with fiscal year 2020, with early adoption permitted. Entities may select retrospective or prospective application to all implementation costs incurred after the adoption date. The adoption of the amendments in this update is not expected to have a material impact on the Company's consolidated financial position and results of operations.

2. Net Income (Loss) Per Share

Basic earnings per share, or 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 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. In periods in which the Company has a net loss, dilutive common stock equivalents are excluded from the calculation of diluted EPS.

The table below presents the computation of basic and diluted EPS:

	Three Months Ended September 30,						Nine Months Ended September 30,
	2018			2017			2018			2017
	(in thousands, except per share amounts)
Numerator:
Net income (loss)	$	(13,935	)	$	(9,167	)	$	(26,510	)	$	10,261
Denominator:
Weighted average common shares outstanding—basic	68,742			66,712			68,256			65,950
Dilutive common stock equivalents	—			—			—			3,541
Weighted average common shares outstanding—diluted	68,742			66,712			68,256			69,491
Net income (loss) per share:
Basic	$	(0.20	)	$	(0.14	)	$	(0.39	)	$	0.16
Diluted	$	(0.20	)	$	(0.14	)	$	(0.39	)	$	0.15

For the three months endedSeptember 30, 2018 and 2017, the Company incurred a net loss and accordingly excluded common stock equivalents for outstanding stock-based awards, which represented all potentially dilutive securities, of 3.8 million and 4.5 million, respectively, from the calculation of diluted net loss per share due to their anti-dilutive nature.

For the nine months endedSeptember 30, 2018, the Company also incurred a net loss and accordingly excluded 3.7 million common stock equivalents for outstanding stock-based awards, which represented all potentially dilutive securities, from the calculation of diluted net loss per share as the impact was anti-dilutive. For the nine months ended September 30, 2017, the Company excluded 1.1 million of common stock equivalents for outstanding stock-based awards from the calculation of diluted net income per share due to their anti-dilutive nature.

3. Business Combinations

Acquisition of Exar Corporation

On May 12, 2017, pursuant to the March 28, 2017 Agreement and Plan of Merger, Eagle Acquisition Corporation, a Delaware corporation and wholly-owned subsidiary of MaxLinear, merged with and into Exar Corporation, or Exar, with Exar surviving as a wholly owned subsidiary of MaxLinear. Under this Agreement and Plan of Merger, the Company agreed to acquire all of Exar's outstanding common stock for $13.00 per share in cash. MaxLinear also assumed certain of Exar's stock-based awards in the merger. MaxLinear paid aggregate cash consideration of $688.1 million including $12.7 million of cash paid to settle certain stock-based awards that were not assumed by MaxLinear in the merger. The Company funded the transaction with cash from the balance sheet of the combined companies, including $235.8 million of cash from Exar, and the net proceeds of approximately $416.8 million from $425.0 million of new transaction debt (Note 8). The Company also assumed a purchase agreement that includes an indemnification obligation from Exar related to a November 9, 2016 business unit divestiture by Exar (Note 13).

In the nine months ended September 30, 2018, the Company made updates to estimates of certain tax-related assets acquired and liabilities assumed with a corresponding net increase to goodwill of $0.3 million related to this acquisition (Note 5). The Company has completed its purchase price allocation accounting associated with this acquisition.

Acquisition of Certain Assets and Assumption of Certain Liabilities of the G.hn business of Marvell Semiconductor, Inc.

On April 4, 2017, the Company consummated the transactions contemplated by a share and asset acquisition agreement with Marvell Semiconductor, Inc., or Marvell, to purchase certain assets and assume certain liabilities of Marvell’s G.hn business, including its Spain legal entity, for aggregate cash consideration of $21.0 million. The Company also hired certain employees of the G.hn business outside of Spain and assumed employment obligations of the Spanish entity acquired, which is now a subsidiary of MaxLinear. The acquired assets and assumed liabilities, together with the employees who joined MaxLinear and its subsidiaries as a result of the transaction, represent a business as defined in ASC 805, Business Combinations. The Company has integrated the acquired assets and employees into its existing business.

4. Restructuring Activity

From time to time, the Company approves and implements restructuring plans as a result of acquisitions, internal resource alignment, and cost saving measures. Such restructuring plans include vacating certain leased facilities, terminating employees, and cancellation of contracts.

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

	Three Months Ended September 30,					Nine Months Ended September 30,
	2018			2017		2018		2017
	(in thousands)
Employee separation expenses	$	440		$	1,689	$	711	$	7,685
Lease related charges (credits)	(315		)	351		1,279		901
Other	111			138		111		138
	$	236		$	2,178	$	2,101	$	8,724

Included in employee separation expenses for the three and nine months endedSeptember 30, 2017 is $0.4 million and $4.9 million of incremental stock-based compensation from the acceleration of certain stock-based awards we assumed from Exar due to change in control provisions upon termination or diminution of authority of former Exar executives and other severance-related charges of $1.3 million and $2.8 million for the three and nine months endedSeptember 30, 2017, respectively.

Lease related charges for the three months endedSeptember 30, 2018 related to adjustments to the net present value of the remaining lease obligation on the cease-use date from exiting certain facilities. Lease related charges for the nine months ended September 30, 2018 primarily related to exiting certain facilities, including impairment of leasehold improvements of $0.7 million. Total sublease income related to leased facilities the Company ceased using was approximately $0.6 million and

15

Table of Contents MAXLINEAR, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

$1.7 million for the three and nine months endedSeptember 30, 2018, respectively. Sublease income for such facilities was approximately $0.5 million and $1.6 million for the three and nine months endedSeptember 30, 2017, respectively.

The following table presents a roll-forward of the Company's restructuring liability for the nine months endedSeptember 30, 2018. The restructuring liability is included in accrued expenses and other current liabilities in the consolidated balance sheets.

	Employee Separation Expenses			Lease Related Charges			Other			Total
	(in thousands)
Balance as of December 31, 2017	$	239		$	2,693		$	107		$	3,039
Restructuring charges	711			1,279			111			2,101
Cash payments	(720		)	(1,456		)	(6		)	(2,182		)
Non-cash items	(93		)	(855		)	(106		)	(1,054		)
Balance as of September 30, 2018	$	137		$	1,661		$	106		$	1,904

5. Goodwill and Intangible Assets

Goodwill

Goodwill arises from the acquisition method of accounting for business combinations and represents the excess of the purchase price over the fair value of the net assets and other identifiable intangible assets acquired. The fair values of net tangible assets and intangible assets acquired are based upon preliminary valuations and the Company's estimates and assumptions are subject to change within the measurement period (potentially up to one year from the acquisition date). During the nine months endedSeptember 30, 2018, the Company adjusted its allocation of purchase price for the acquisition of Exar related to updates to estimates of certain tax-related assets acquired and liabilities assumed with a corresponding net increase in goodwill of $0.3 million.

The following table presents the changes in the carrying amount of goodwill:

	Carrying Amount
	(in thousands)
Balance as of December 31, 2017	$	237,992
Adjustments	338
Balance as of September 30, 2018	$	238,330

The Company performs an annual goodwill impairment assessment on October 31st each year, using a two-step quantitative assessment. 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.

In addition to its annual review, the Company performs a test of impairment when indicators of impairment are present. During the nine months endedSeptember 30, 2018 and 2017, no indications of impairment of the Company's goodwill balances were identified and, as a result, no goodwill impairment was recognized.

Acquired Intangibles

Finite-lived Intangible Assets

The following table sets forth the Company’s finite-lived intangible assets resulting from business acquisitions and other purchases, which continue to be amortized:

The following table sets forth amortization expense associated with finite-lived intangible assets, which is included in the consolidated statements of operations as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2018		2017		2018		2017
	(in thousands)				(in thousands)
Cost of net revenue	$	8,979	$	7,907	$	26,935	$	16,851
Research and development	33		137		117		412
Selling, general and administrative	7,994		9,924		23,982		20,067
	$	17,006	$	17,968	$	51,034	$	37,330

Amortization of finite-lived intangible assets in cost of net revenue in the consolidated statements of operations results primarily from acquired developed technology.

The following table sets forth the activity during the nine months endedSeptember 30, 2018 related to finite-lived intangible assets resulting from amortization and impairment losses:

	Carrying Amount
	(in thousands)
Balance as of December 31, 2017	$	310,645
Amortization	(51,034		)
Impairment losses	(2,198		)
Balance as of September 30, 2018	$	257,413

The Company regularly reviews the carrying amount of its long-lived assets subject to depreciation and amortization, as well as the related useful lives, to determine whether indicators of impairment may exist that warrant adjustments to carrying values or estimated useful lives. An impairment loss is 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 is measured based on the excess of the carrying amount of the asset over the asset’s fair value. Impairment losses related to finite-lived intangible assets for the three and nine months endedSeptember 30, 2018 were $2.2 million and related to developed technology acquired from Exar.

Total	$	257,413

Indefinite-lived Intangible Assets

As of September 30, 2018 and December 31, 2017, total indefinite-lived intangible assets, which consist of acquired in-process research and development, were $4.4 million.

The Company performs its annual assessment of indefinite-lived intangible assets on October 31 each year or more frequently if events or changes in circumstances indicate that the asset might be impaired utilizing a qualitative test as a precursor to the quantitative test comparing the fair value of the assets with their carrying amount. Based on the qualitative test, if it is more likely than not that indicators of impairment exists, the Company proceeds to perform a quantitative analysis. During the nine months endedSeptember 30, 2018, no indicators of impairment were identified and, as a result, no IPR&D impairment losses were recorded. In the nine months endedSeptember 30, 2017, the Company recognized IPR&D impairment losses of $2.0 million related to a single IPR&D project of Exar, which was abandoned.

The fair value of the Company’s financial instrument is the amount that would be received in an asset sale or paid to transfer a liability in an orderly transaction between unaffiliated market participants and is recorded using a hierarchical 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.

Table of Contents MAXLINEAR, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

The Company classifies its financial instrument within Level 2 of the fair value hierarchy on the basis of models utilizing market observable inputs. The interest rate swap has been valued on the basis of valuations provided by third-party pricing services, as derived from standard valuation or pricing models. The pricing services may use market-based observable inputs for the interest rate swap over the term of the swap, including one month LIBOR-based yield curves 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. The Company also considers the risk of nonperformance by assessing the swap counterparty's credit risk in the estimate of fair value of the interest rate swap. As of September 30, 2018 and December 31, 2017, the Company has not made any adjustments to the valuations obtained from its third-party pricing providers. 

The following table presents a summary of the Company’s financial instruments that were measured at fair value on a recurring basis and the related level of the fair value hierarchy:

On May 12, 2017, the Company entered into a credit agreement with certain lenders and a collateral agent in connection with the acquisition of Exar (Note 3). The credit agreement provides for an initial secured term B loan facility, or the “Initial Term Loan,” in an aggregate principal amount of $425.0 million. The credit agreement permits the Company to request incremental loans in an aggregate principal amount not to exceed the sum of $160.0 million (subject to adjustments for any voluntary prepayments), plus an unlimited amount that is subject to pro forma compliance with certain secured leverage ratio and total leverage ratio tests. Incremental loans are subject to certain additional conditions, including obtaining additional commitments from the lenders then party to the credit agreement or new lenders.

Loans under the credit agreement bear interest, at the Company’s option, at a rate equal to either (i) a base rate equal to the highest of (x) the federal funds rate, plus 0.50%, (y) the prime rate then in effect and (z) an adjusted LIBOR rate determined on the basis of a one- three- or six-month interest period, plus 1.0% or (ii) an adjusted LIBOR rate, subject to a floor of 0.75%, in each case, plus an applicable margin of 2.50% in the case of LIBOR rate loans and 1.50% in the case of base rate loans. Commencing on September 30, 2017, the Initial Term Loan will amortize in equal quarterly installments equal to 0.25% of the original principal amount of the Initial Term Loan, with the balance payable on the maturity date. The Initial Term Loan has a term of seven years and will mature on May 12, 2024, at which time all outstanding principal and accrued and unpaid interest on the Initial Term Loan must be repaid. The Company is also required to pay fees customary for a credit facility of this size and type.

The Company is required to make mandatory prepayments of the outstanding principal amount of term loans under the credit agreement with the net cash proceeds from the disposition of certain assets and the receipt of insurance proceeds upon certain casualty and condemnation events, in each case, to the extent not reinvested within a specified time period, from excess cash flow beyond stated threshold amounts, and from the incurrence of certain indebtedness. The Company has the right to prepay its term loans under the credit agreement, in whole or in part, at any time without premium or penalty, subject to certain limitations and a 1.0% soft call premium applicable during the first six months of the loan term. The Company exercised its right to prepay and made aggregate prepayments of principal of $148.0 million from origination through September 30, 2018.

The Company’s obligations under the credit agreement are required to be guaranteed by certain of its domestic subsidiaries meeting materiality thresholds set forth in the credit agreement. Such obligations, including the guaranties, are secured by substantially all of the assets of the Company and the subsidiary guarantors pursuant to a security agreement with the collateral agent.

The credit agreement contains customary affirmative and negative covenants, including covenants limiting the ability of the Company and its restricted subsidiaries to, among other things, incur debt, grant liens, undergo certain fundamental changes, make investments, make certain restricted payments, and sell assets, in each case, subject to limitations and exceptions. As of September 30, 2018, the Company was in compliance with such covenants. The credit agreement also contains customary events of default that include, among other things, certain payment defaults, cross defaults to other indebtedness, covenant defaults, change in control defaults, judgment defaults, and bankruptcy and insolvency defaults. If an event of default exists, the lenders may require immediate payment of all obligations under the credit agreement, and may

22

Table of Contents MAXLINEAR, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

exercise certain other rights and remedies provided for under the credit agreement, the other loan documents and applicable law.

As of September 30, 2018 and December 31, 2017, the weighted average effective interest rate payable on the long-term debt was approximately 4.6% and 4.1%, respectively.

The debt is carried at its principal amount, net of unamortized debt discount and issuance costs, and is not adjusted to fair value each period. The issuance date fair value of the liability component of the debt in the amount of $398.5 million was determined using a discounted cash flow analysis, in which the projected interest and principal payments were discounted back to the issuance date of the term loan at a market interest rate for nonconvertible debt of 4.6%, which represents a Level 3 fair value measurement. The debt discount of $2.1 million and debt issuance costs of $6.0 million are being amortized to interest expense using the effective interest method from the issuance date through the contractual maturity date of the term loan of May 12, 2024.

During the three and nine months endedSeptember 30, 2018, the Company recognized total amortization of debt discount and debt issuance costs of $0.3 million and $0.9 million, respectively, to interest expense. During the three and nine months endedSeptember 30, 2017, the Company recognized total amortization of debt discount and debt issuance costs of $0.3 million and $0.5 million, respectively, to interest expense.

The approximate fair value of the term loan as of September 30, 2018 and December 31, 2017was $265.8 million and $360.0 million, respectively, which was estimated on the basis of inputs that are observable in the market and which is considered a Level 2 measurement method in the fair value hierarchy.

As of September 30, 2018 and December 31, 2017, the remaining principal balance on the term loan was $277.0 million and $355.0 million, respectively. The remaining principal balance is due on May 12, 2024 at the maturity date on the term loan.

Interest Rate Swap

In November 2017, the Company entered into a fixed-for-floating interest rate swap with an amortizing notional amount to swap a substantial portion of variable rate LIBOR interest payments under its term loans for fixed interest payments bearing an interest rate of 1.74685%. The Company's outstanding debt is still subject to a 2.5% fixed applicable margin during the term of the loan. The interest rate swap is designated as a cash flow hedge of a portion of floating rate interest payments on long-term debt and effectively fixes the interest rate on a substantial portion of the Company’s long-term debt at approximately 4.25%. Accordingly, the Company applies cash flow hedge accounting to the interest rate swap and it is recorded at fair value as an asset or liability and the effective portion of changes in the fair value of the interest rate swap, as measured quarterly, are reported in other comprehensive income (loss). As of September 30, 2018 and December 31, 2017, the fair value of the interest rate swap asset was $2.5 million and $0.7 million (Note 6), respectively, and is included in other long-term assets in the consolidated balance sheets. The increase in fair value related to the interest rate swap asset included in other comprehensive income for the nine months endedSeptember 30, 2018 was $1.7 million. The decrease in fair value for the three months endedSeptember 30, 2018 included in other comprehensive income was $0.01 million. The interest rate swap expires in October 2020 and the total $1.7 million of unrealized gain recorded in accumulated other comprehensive income at September 30, 2018 is not expected to be recorded against interest expense over the next twelve months.

9. Stock-Based Compensation and Employee Benefit Plans

Employee Stock-Based Benefit Plans

At September 30, 2018, the Company had stock-based compensation awards outstanding under the following plans: the 2004 Stock Plan, the 2010 Equity Incentive Plan, as amended, or 2010 Plan, the 2010 Employee Stock Purchase Plan, or ESPP, and plans under which equity incentive awards were assumed in connection with the acquisitions of Entropic in 2015 and Exar Corporation in 2017. Refer to the Company’s Annual Report for a summary of the Company's stock-based compensation and equity plans as of December 31, 2017. There have been no material changes to the terms of the Company's equity incentive plans during the nine months endedSeptember 30, 2018. All current stock awards are issued under the 2010 Plan and ESPP.

As of September 30, 2018, the number of shares of common stock available for future issuance under the 2010 Plan was 13,287,501 shares. As of September 30, 2018, the number of shares of common stock available for future issuance under the ESPP was 2,254,806 shares.

Stock-Based Compensation

The Company recognizes stock-based compensation in the consolidated statements of operations, based on the department to which the related employee reports, as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
	2018		2017		2018		2017
	(in thousands)				(in thousands)
Cost of net revenue	$	131	$	93	$	357	$	231

Restructuring	—		401		—		4,915
	$	7,927	$	7,796	$	23,709	$	24,898

The total unrecognized compensation cost related to unvested restricted stock units and restricted stock awards as of September 30, 2018 was $60.6 million, and the weighted average period over which these equity awards are expected to vest is 2.76 years. The total unrecognized compensation cost related to unvested stock options as of September 30, 2018 was $5.5 million, and the weighted average period over which these equity awards are expected to vest is 2.92 years.

Restricted Stock Units and Restricted Stock Awards

The Company calculates the fair value of restricted stock units based on the fair market value of the Company's common stock on the grant date. Stock based compensation is recognized over the vesting period using the straight-line method.

A summary of the Company’s restricted stock unit and restricted stock award activity is as follows:

	Number of Shares (in thousands)		Weighted-Average Grant-Date Fair Value per Share
Outstanding at December 31, 2017	3,183		$	20.13
Granted	2,362		19.42
Vested	(1,342	)	18.57
Canceled	(488	)	20.71
Outstanding at September 30, 2018	3,715		20.18

Employee Stock Purchase Rights and Stock Options

The Company uses the Black-Scholes valuation model to calculate the grant-date fair value of employee stock purchase rights and stock options. Stock based compensation expense is recognized over the vesting period using the straight-line method.

Employee Stock Purchase Rights

During the nine months endedSeptember 30, 2018, there were 151,840 shares of common stock purchased under the ESPP at a weighted average price of $16.14.

The fair values of employee stock purchase rights were estimated using the Black-Scholes option pricing model at their respective grant date using the following assumptions:

	Nine Months Ended
	September 30, 2018
Weighted-average grant date fair value per share	$	5.37
Risk-free interest rate	2.09		%
Dividend yield	—		%
Expected life (in years)	0.50
Volatility	46.00		%

24

Table of Contents MAXLINEAR, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

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 expected term is the duration of the offering period for each grant date. In addition, the estimated volatility incorporates the historical volatility over the expected term based on the Company's daily closing stock prices.

Stock Options

A summary of the Company’s stock options activity is as follows:

	Number of Options (in thousands)		Weighted-Average Exercise Price		Weighted-Average Contractual Term (in years)	Aggregate Intrinsic Value (in thousands)
Outstanding at December 31, 2017	3,069		$	8.95
Granted	335		18.40
Exercised	(285	)	7.76
Canceled	(83	)	16.69
Outstanding at September 30, 2018	3,036		$	9.90	2.30	$	30,982
Vested and expected to vest at September 30, 2018	2,998		$	9.79	2.26	$	30,896
Exercisable at September 30, 2018	2,506		$	8.32	1.52	$	29,502

The fair values of stock options were estimated using the Black-Scholes option pricing model on the grant date using the following assumptions:

	Nine Months Ended
	September 30, 2018
Weighted-average grant date fair value per share	$	8.14
Risk-free interest rate	2.76		%
Dividend yield	—		%
Expected life (in years)	5.51
Volatility	44.30		%

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, the estimated volatility incorporates the historical volatility of the Company.

The intrinsic value of stock options exercised was $0.1 million and $0.9 million in the three months endedSeptember 30, 2018 and 2017, respectively. The intrinsic value of stock options exercised was $4.0 million and $15.2 million in the nine months endedSeptember 30, 2018 and 2017, respectively.

Cash received from exercise of stock options was $0.1 million and $1.1 million during the three months endedSeptember 30, 2018 and 2017, respectively. Cash received from exercise of stock options was $1.3 million and $7.1 million during the nine months endedSeptember 30, 2018 and 2017, respectively.

The tax benefit from stock options exercised was $1.2 million and $0.9 million during the three months endedSeptember 30, 2018 and 2017, respectively. The tax benefit from stock options exercised was $3.7 million and $11.2 million during the nine months endedSeptember 30, 2018 and 2017, respectively.

Table of Contents MAXLINEAR, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

Employee Incentive Bonus

The Company settles a majority of bonus awards for its employees, including executives, in shares of common stock under the 2010 Equity Incentive Plan. When bonus awards are settled in common stock issued under the 2010 Equity Incentive Plan, the number of shares issuable to plan participants is determined based on the closing price of the Company's common stock as determined in trading on the New York Stock Exchange on a date approved by the Board of Directors. In connection with the Company's bonus programs, in February 2018, the Company issued 0.3 million freely-tradable shares of the Company's common stock in settlement of bonus awards to employees, including executives, for the 2017 performance period. At September 30, 2018, the Company has an accrual of $6.5 million for bonus awards for employees for year-to-date achievement in the 2018 performance period. The Company's compensation committee retains discretion to effect payment in cash, stock, or a combination of cash and stock.

10. Income Taxes

The provision for income taxes primarily relates to projected federal, state, and foreign income taxes. To determine the quarterly provision for income taxes, the Company uses an estimated annual effective tax rate, which is generally based on expected annual income and statutory tax rates in the various jurisdictions in which the Company operates. In addition, the tax effects of certain significant or unusual items are recognized discretely in the quarter during which they occur and can be a source of variability in the effective tax rates from quarter to quarter.

The Company utilizes the asset and liability method of accounting for income taxes, under which deferred taxes are determined based on temporary differences between the financial statement and tax basis of assets and liabilities using tax rates expected to be in effect during the years in which the temporary differences reverse. The Company records a valuation allowance to reduce its deferred taxes to the amount it believes is more likely than not to be realized. In making such determination, the Company considers all available positive and negative evidence quarterly, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and recent financial performance.  Forming a conclusion that a valuation allowance is not required is difficult when there is negative evidence such as cumulative losses in recent years. Based upon the Company's review of all positive and negative evidence, the Company released the valuation allowance against certain of its federal deferred tax assets during the three months ended June 30, 2017. The Company continues to have a valuation allowance on its state deferred taxes, certain of its federal deferred tax assets, and certain foreign deferred tax assets in jurisdictions where the Company has cumulative losses or otherwise is not expected to utilize certain tax attributes. The Company does not incur expense or benefit in certain tax free jurisdictions in which it operates.

The Company recorded an income tax benefit of $2.1 million in the three months endedSeptember 30, 2018 and an income tax benefit of $6.3 million for the three months endedSeptember 30, 2017. The Company recorded an income tax provision of $7.3 million for the nine months endedSeptember 30, 2018 and an income tax benefit of $33.8 million for the nine months endedSeptember 30, 2017.

The income tax provision in the nine months endedSeptember 30, 2018 primarily relates to the mix of pre-tax income among jurisdictions (including the effects of certain intercompany royalty payments), excess tax benefits related to stock-based compensation, and release of uncertain tax positions under ASC 740-10.

The income tax benefit in the nine months endedSeptember 30, 2017 primarily relates to the release of the federal valuation allowance during the three months ended June 30, 2017.

Income tax positions must meet a more-likely-than-not threshold to be recognized. Income tax positions that previously failed to meet the more-likely-than-not threshold are recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not threshold are derecognized in the first financial reporting period in which that threshold is no longer met. The Company records potential penalties and interest accrued related to unrecognized tax benefits within the consolidated statements of income as income tax expense.

During the nine months endedSeptember 30, 2018, the Company’s unrecognized tax benefits increased by $0.5 million. The Company does not expect its unrecognized tax benefits to change significantly over the next 12 months. Accrued interest and penalties associated with uncertain tax positions as of September 30, 2018 were approximately $0.8 million and $0.2 million, respectively.

The Company is subject to federal and state income tax in the United States and is also subject to income tax in various states and foreign tax jurisdictions. At September 30, 2018, the Company’s tax years for 2013, 2012, and 2009 and forward are

26

Table of Contents MAXLINEAR, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

subject to examination by federal, state, and foreign tax authorities, respectively. The Company is under a routine compliance review by the Inland Revenue Authority of Singapore for its 2016 and 2017 tax years. In addition, the Company is currently under examination by the California Franchise Tax Board for the 2014 and 2015 tax years. The Company does not expect these examinations or reviews to have a material effect on the Company's consolidated financial position or results of operations.  However, certain of the Company's state tax attribute carryforwards, which currently have a full valuation allowance, could be reduced.

In April 2017, the Company's subsidiary in Singapore began operating under certain tax incentives in Singapore, which are generally effective through March 2022, and are conditional upon meeting certain employment and investment thresholds in Singapore. Under the incentives, qualifying income derived from certain sales of the Company's integrated circuits is taxed at a concessionary rate over the incentive period, and there are reduced Singapore withholding taxes on certain intercompany royalties during the incentive period. Primarily because of the Company's Singapore net operating losses and a full valuation allowance in Singapore, the incentives did not have a material impact on the Company's income tax provision in the nine months ended September 30, 2018.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act, or the Tax Act. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning in 2018, the transition of U.S international taxation from a worldwide tax system to a territorial system, which includes a new federal tax on global intangible low-taxed income (Global Minimum Tax or GMT), and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017. In its 2017 consolidated financial statements, the Company calculated its best estimate of the impact of the Tax Act in its 2017 income tax benefit in accordance with its understanding of the Tax Act and guidance available as of the date of the filing of the Annual Report.

In addition, the SEC Staff issued SAB 118, which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act.

The Company was able to make reasonable estimates of certain effects and, therefore, recorded certain provisional adjustments in the 2017 income tax benefit. Refer to Note 10 to the Company's consolidated financial statements included in the Annual Report for further details. During the nine months ended September 30, 2018, the Company recognized no adjustments to the provisional amounts recorded at December 31, 2017. Additionally, the Company has provided provisional amounts for the legislative provisions that are effective as of January 1, 2018, including, but not limited to, the creation of the base erosion anti-abuse tax (BEAT), a new global minimum tax, GMT, a new limitation on deductible interest expense, and limitations on the use of net operating losses.

At September 30, 2018, the Company's accounting for certain elements of the Tax Act is incomplete. The provisional amounts recorded are subject to revisions as the Company completes its analysis of the Tax Act, collects and prepares necessary data, and interprets any additional guidance issued by the U.S. Treasury Department, Internal Revenue Service, or IRS, FASB, and other standard-setting and regulatory bodies. Adjustments to the provisional amounts may materially impact the Company's consolidated income tax provision (benefit) and effective tax rates in the period(s) in which such adjustments are made. In all cases, the Company will continue to make and refine calculations as additional analysis is completed. The Company's accounting for the tax effects of the Tax Act will be completed during the one-year measurement period.

Under U.S. GAAP, the Company is allowed to make an accounting policy choice with respect to the GMT of either (1) treating taxes due on future U.S. inclusions in taxable income related to GMT as a current-period expense when incurred or (2) as a component of deferred income taxes. The Company will make its accounting policy election for this item when its analysis is complete, during the measurement period. At September 30, 2018, because the Company is still evaluating the GMT provisions and an analysis of future taxable income that is subject to GMT, the Company has included GMT related to current year operations only in the estimated annual effective tax rate and has not provided additional GMT on deferred items.

⁽¹⁾ Due to the adoption of ASC 606 using the modified retrospective method, prior period amounts have not been adjusted to reflect the change to recognize certain distributor sales upon sale to the distributor, or the sell-in method, from recognition upon the Company's sale to the distributors' end customers, or the sell-through method, which required the deferral of revenue and profit on such distributor sales.

Contract Liabilities

As of September 30, 2018, customer contract liabilities consist of estimates of obligations to deliver rebates to customers in the form of units of products and were approximately $0.2 million. Revenue recognized in the three and nine months endedSeptember 30, 2018 that was included in the contract liability balance as of January 1, 2018 was immaterial.

There were no material changes in the contract liabilities balance during the three and nine months endedSeptember 30, 2018.

Obligations to Customers for Price Adjustments and Returns and Assets for Right-of-Returns

As of September 30, 2018, obligations to customers consisting of estimates of price protection rights offered to the Company's end customers totaled $14.4 million and are included in accrued price protection liability in the consolidated balance sheets. For activity in this account, including amounts included in net revenue, refer to Note 7. Other obligations to customers representing estimates of price adjustments to be claimed by distributors upon sell-through of their inventory to their end customer and estimates of stock rotation returns to be claimed by distributors on products sold as of September 30, 2018 were $6.2 million and $1.0 million, respectively, and are included in accrued expenses and other current liabilities in the consolidated balance sheets (Note 7). The increase in revenue from net changes in transaction prices for amounts included in obligations to customers for price adjustments as of January 1, 2018 was not material. As of September 30, 2018, right of return assets under customer contracts representing the estimates of product inventory the Company expects to receive from customers in stock rotation returns were approximately $0.2 million.

Total sublease income related to leased facilities the Company ceased using in connection with a restructuring plan for the three months endedSeptember 30, 2018 and 2017 was approximately $0.6 million and $0.5 million, respectively (Note 4). Total sublease income related to leased facilities the Company ceased using in connection with a restructuring plan for the nine months endedSeptember 30, 2018 and 2017 was approximately $1.7 million and $1.6 million, respectively.

Exar iML Divestiture Indemnification

Under the terms of the purchase agreement relating to the November 9, 2016 divestiture of Integrated Memory Logic Limited, or iML, by Exar, Exar agreed to indemnify the purchaser of the business unit for breaches of representations and warranties and covenants and for certain other matters. Exar also agreed to place $5.0 million of the total purchase price into an escrow account for a period of 18 months to partially secure its indemnification obligations under the purchase agreement; of this amount, $0.8 million remains in escrow as of September 30, 2018; $1.3 million has been released to the purchaser of iML and $2.9 million has been released to Exar through September 30, 2018. Exar’s indemnification obligations for breaches of representations and warranties survived for 12 months from the closing of the sale transaction, except for breaches of representations and warranties covering intellectual property, which survived for 18 months, and breaches of representations

31

Table of Contents MAXLINEAR, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

and warranties of certain fundamental representations, which survive until the expiration of the applicable statute of limitations. Exar’s maximum indemnification obligation for breaches of representations and warranties, other than intellectual property and fundamental representations, was $13.6 million, its maximum indemnification obligation for breaches of intellectual property representations was $34.0 million, and is maximum indemnity obligation for breaches of fundamental representations is the full purchase price amount (approximately $136.0 million). The aggregate amount recovered by the purchaser in accordance with the indemnification provisions with respect to matters that are subject to the intellectual property representations, together with the aggregate amount recovered by the Buyer in accordance with the indemnification provisions with respect to matters that are subject to the general representations and warranties (other than fundamental representations), will in no event exceed $34.0 million. The Company believes it does not have a material indemnification obligation as of September 30, 2018; however, if the Company were required to make payments in satisfaction of these indemnification obligations related to breaches of representations and warranties of certain fundamental obligations which have not yet expired, it could have a material adverse effect on the Company's business, financial condition, results of operations, and cash flows.

CrestaTech Litigation

On January 21, 2014, CrestaTech Technology Corporation, or CrestaTech, filed a complaint for patent infringement against the Company in the United States District Court of Delaware, or the District Court Litigation. In its complaint, CrestaTech alleged that the Company infringed U.S. Patent Nos. 7,075,585, or the ‘585 Patent and 7,265,792, or the ‘792 Patent. In addition to asking for compensatory damages, CrestaTech alleged willful infringement and sought a permanent injunction. CrestaTech also named Sharp Corporation, Sharp Electronics Corp. and VIZIO, Inc. as defendants based upon their alleged use of the Company's television tuners.

On January 28, 2014, CrestaTech filed a complaint with the U.S. International Trade Commission, or ITC, again naming, among others, MaxLinear, Sharp, Sharp Electronics, and VIZIO, or 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. which are collectively referred to with MaxLinear, Sharp and VIZIO as the Company Respondents. CrestaTech’s ITC complaint alleged 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 MaxLinear's accused products that CrestaTech alleged infringe the same two patents asserted in the Delaware action. Through its ITC complaint, CrestaTech sought an exclusion order preventing entry into the United States of certain of the Company's television tuners and televisions containing such tuners from Sharp, Sharp Electronics, and VIZIO. CrestaTech also sought 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 March 10, 2014, the court stayed the District Court Litigation pending resolution of the ITC Investigation.

On December 15, 2014, the ITC held a trial in the ITC Investigation. On February 27, 2015, the Administrative Law Judge, or the ALJ, issued a written Initial Determination, or 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 Company's television tuners and televisions incorporating those tuners manufactured and sold by certain customers infringe three claims of the ‘585 Patent (claims 10, 12 and 13), 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 ITC subsequently issued its opinion, which terminated its investigation. The opinion affirmed the findings of the ALJ 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 ALJ's finding of infringement with respect to the three claims of the '585 Patent that were not held to be invalid.

On November 30, 2015, CrestaTech filed an appeal of the ITC decision with the United States Court of Appeals for the Federal Circuit, or the Federal Circuit. On March 7, 2016, CrestaTech voluntarily dismissed its appeal, resulting in a final determination of the ITC Investigation in the Company's favor.

In addition, the Company has filed four petitions for inter partes review, or IPR, by the US Patent Office, two for each of the CrestaTech patents asserted against the Company. The Patent Trial and Appeal Board, or the PTAB, did not institute two of

32

Table of Contents MAXLINEAR, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

these IPRs as being redundant to IPRs filed by another party that were already underway for the same CrestaTech patent.  The remaining two petitions were instituted or instituted-in-part meaning, together with the IPRs filed by third parties, there were currently six IPR proceedings instituted involving the two CrestaTech patents asserted against the Company. 

In October 2015, the PTAB issued final decisions in two of the six pending IPR proceedings (one for each of the two asserted patents), holding that all of the reviewed claims are unpatentable. Included in these decisions was one of the three claims of the ‘585 Patent (claim 10) mentioned above in connection with the ITC’s final decision. CrestaTech appealed the PTAB’s decisions at the Federal Circuit. On November 8, 2016, the Federal Circuit issued an opinion affirming the PTAB’s finding of unpatentability.

In August 2016, the PTAB issued final written decisions in the remaining four pending IPR proceedings (two for each of the asserted patents), holding that many of the reviewed claims - including the two remaining claims of the ‘585 Patent which the ITC held were infringed - are unpatentable. The parties have appealed the two decisions related to the ‘585 Patent; however, no appeals were filed as to the PTAB's rulings for the ‘792 Patent. The Federal Circuit heard oral argument on these appeals on December 4, 2017. On December 7, the Federal Circuit issued a Rule 36 affirmance in one of the '585 appeals, affirming that the two remaining claims that the ITC had ruled were valid and infringed (claims 12 and 13) are unpatentable. On January 25, 2018, the Federal Circuit issued its ruling in the other ‘585 appeal, vacating the PTAB's ruling that certain claims were not unpatentable and remanding to the PTAB for further analysis of whether CrestaTech is estopped from arguing and/or has waived the right to argue whether six dependent claims are patentable.

As a result of these IPR decisions, all 13 claims that CrestaTech asserted against the Company in the ITC Investigation have been found to be unpatentable by the PTAB and the Federal Circuit.

On March 18, 2016, CrestaTech filed a petition for Chapter 7 bankruptcy in the Northern District of California. As a result of this proceeding, all rights in the CrestaTech asserted patents, including the right to control the pending litigation, were assigned to CF Crespe LLC, or CF Crespe. CF Crespe became the named party in the then-pending IPRs, Federal Circuit appeal and District Court Litigation.

In April 2017, the Delaware court continued the stay of the District Court Litigation per the parties’ request, pending resolution of the Federal Circuit appeals in the IPRs. On April 3, 2018, the District Court dismissed the District Court Litigation. While Crespe has subsequently suggested that this dismissal may have been in error, Crespe has taken no action to date to re-instate the case. Indeed, in its bankruptcy proceeding Crespe has stated that it “no longer has any valid patent claims that it is asserting in any of the proceedings purchased through the Sale Agreement,” which includes the District Court Litigation against the Company. In re Cresta Technology Corporation, Case No. 16-50808 (N.D. Cal. Bank. 2016) at Dkt. No. 270.

The Company cannot predict the outcome of the District Court Litigation, or the IPRs. Any adverse determination in the District Court Litigation could have a material adverse effect on the Company's business, financial condition, results of operations and cash flows.

Trango Systems, Inc. Litigation

On or about August 2, 2016, Trango Systems, Inc., or Trango, filed a complaint in the Superior Court of California, County of San Diego, Central Division, against defendants Broadcom Corporation, Inc., or Broadcom, and the Company, collectively, Defendants. Trango is a purchaser that alleges various fraud, breach of contract, and interference with economic relations claims in connection with the discontinuance of a chip line the Company acquired from Broadcom in 2016. Trango seeks unspecified general and special damages, pre-judgment interest, expenses and costs, attorneys’ fees, punitive damages, and unspecified injunctive and equitable relief. On June 23, 2017, the Court sustained the Company's demurrer to each cause of action in the second amended complaint filed on or about December 6, 2016. Trango filed its third amended complaint on or about July 13, 2017. On February 23, 2018, the Court sustained, in part, the Company's demurrer, dismissing with prejudice the cause of action for breach of a written contract, and Trango voluntarily dismissed its cause of action for breach of an implied-in-fact contract. The remaining causes of action have been permitted to proceed. On March 15, 2018, Trango filed its fourth amended complaint. The Company filed its answer on April 17, 2018. Also, on April 17, Broadcom filed a cross-complaint against the Company, alleging causes of action for indemnity, contribution and apportionment, and declaratory relief. Broadcom voluntarily dismissed the cross-complaint on June 8, 2018. The trial date is set for May 10, 2019. The Company intends to vigorously defend against the lawsuit as it proceeds.

The Company cannot predict the outcome of the Trango Systems, Inc. litigation. Any adverse determination in the Trango Systems, Inc. litigation could have a material adverse effect on the Company's business, financial condition, results of operations and cash flows.

Other Matters

In addition, from time to time, the Company is subject to threats of litigation or actual litigation in the ordinary course of business, some of which may be material. Other than the CrestaTech and Trango litigation described above, the Company believes that there are no other currently pending litigation matters that, if determined adversely by the Company, would have a material effect on the Company's business or that would not be covered by the Company's existing liability insurance.

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

Forward-Looking Statements

The following discussion and analysis of the financial condition and results of our operations should be read in conjunction with the consolidated financial statements and related notes included elsewhere in this report. This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those discussed below. Factors that could cause or contribute to such differences include, but are not limited to, those identified below, and those discussed in the section titled “Risk Factors” included elsewhere in this report.

Overview

We are a provider of radio-frequency, or RF, high-performance analog, and mixed-signal communications systems-on-chip solutions for the connected home, wired and wireless infrastructure, and industrial and multi-market applications. We are a fabless integrated circuit design company whose products integrate all or substantial portions of a broadband communication system. In most cases, these products are designed on a single silicon-die, using standard digital CMOS processes and conventional packaging technologies. We believe this enables our solutions to achieve superior power, performance, and cost advantages relative to our industry competition. Our customers include electronics distributors, module makers, original equipment manufacturers (OEMs), and original design manufacturers (ODMs), who incorporate our products in a wide range of electronic devices. Examples of such end market electronic devices incorporating our products include cable DOCSIS broadband modems and gateways; wireline connectivity devices for in-home networking applications; RF transceivers and modems for wireless carrier access and backhaul infrastructure; fiber-optic modules for data center, metro, and long-haul transport networks; video set-top boxes and gateways; hybrid analog and digital televisions, direct broadcast satellite outdoor and indoor units; and power management and interface products used in these and a range of other markets.

We combine our high-performance RF and mixed-signal semiconductor design skills with our expertise in digital communications systems, software, high-performance analog, and embedded systems to provide highly integrated semiconductor devices and platform-level solutions that are manufactured using a range of semiconductor manufacturing processes, including low-cost complementary metal oxide semiconductor, or CMOS, process technology, Silicon Germanium, Gallium Arsenide, BiCMOS and Indium Phosphide process technologies. Our ability to design analog and mixed-signal circuits in CMOS allows us to efficiently combine analog and digital signal processing functionality in the same integrated circuit. As a result, our solutions have high levels of functional integration and performance, small silicon die size, and low power consumption. Moreover, with our acquisition of Exar Corporation in 2017, we are uniquely positioned to offer customers a combination of proprietary CMOS-based radio system architectures that provide the benefits of superior RF system performance, along with high-performance analog interface and power management solutions that enable shorter design cycles, significant design flexibility, and low system cost across a wide range of broadband communications, wired and wireless infrastructure, and industrial and multimarket applications.

Our net revenue has grown from approximately $0.6 million in fiscal year 2006 to $420.3 million in fiscal year 2017. In the nine months endedSeptember 30, 2018, revenues were $297.4 million. In fiscal year 2017 and in the three and nine months endedSeptember 30, 2018, our net revenue was derived primarily from sales of RF receivers and RF receiver systems-on-chip and connectivity solutions into broadband operator voice and data modems and gateways and connectivity adapters, global analog and digital RF receiver products for analog and digital pay-TV applications, radio and modem solutions into wireless carrier access and backhaul infrastructure platforms, high-speed optical interconnect solutions sold into optical modules for data-center, metro and long-haul networks, and high-performance interface and power management solutions into a broad range

34

of communications, industrial, automotive and multi-market applications. 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 smartphone market, storage networking market, cable infrastructure market, industrial and automotive markets, and optical module and telecommunications infrastructure markets.

Products shipped to Asia accounted for 81% and 86% of our net revenue in the three months endedSeptember 30, 2018 and 2017, respectively. Products shipped to Asia accounted for 81% and 90% of our net revenue in the nine months endedSeptember 30, 2018 and 2017, respectively. Although a large percentage of our products are 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 in the three and nine months endedSeptember 30, 2018 and 2017 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 in the three and nine months endedSeptember 30, 2018 and 2017 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. A growing portion of our business consists of products, specifically our high-speed optical interconnect products, that are shipped to, and are ultimately consumed in Asian markets, with the majority of these products being purchased by end customers in China.

A significant portion of our net revenue has historically been generated by a limited number of customers. In the three months ended September 30, 2018, although none of our customers individually accounted for 10% or more of our net revenue, our ten largest customers collectively accounted for 69% of our net revenue. In the nine months ended September 30, 2018, one of our customers, Arris Group, Inc., or Arris, accounted for 21% of our net revenue, and our ten largest customers collectively accounted for 63% of our net revenue. In the three months ended September 30, 2017, Arris accounted for 26% of our net revenue, and our ten largest customers collectively accounted for 58% of our net revenue. In the nine months ended September 30, 2017, Arris accounted for 27% of our net revenue, and our ten largest customers collectively accounted for 60% of our net revenue. For certain customers, we sell multiple products into disparate end user applications such as cable modems, satellite set-top boxes and broadband gateways.

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 industrial and wired and wireless infrastructure markets, a design-in can have a product life cycle of 24 to 60 months and beyond.

On March 29, 2017, each share of our then outstanding Class A common stock and Class B common stock and shares underlying our then outstanding stock options, restricted stock units and restricted stock awards automatically converted into a single class of our common stock or rights to receive shares of a single class of our common stock pursuant to the terms of our Fifth Amended and Restated Certificate of Incorporation. The conversion had no impact on the total number of issued and outstanding shares of our capital stock; the Class A shares and Class B shares converted into an equivalent number of shares of our common stock. In addition, the conversion did not increase the total number of authorized shares of our common stock, which prior to the conversion was, and remains, 550,000,000 shares. However, our total number of authorized shares of capital stock was reduced from 1,575,000,000 to 1,509,554,147, to account for the retirement of the Class A shares and Class B shares that were outstanding at the time of the conversion. Following the conversion, our authorized capital stock includes 441,123,947 Class A shares and 493,430,200 Class B shares, which represents Class A shares and Class B shares that were authorized but unissued at the time of the conversion. No additional Class A shares or Class B shares will be issued following the conversion.

35

Following the conversion, each share of our common stock is entitled to one vote per share and otherwise has the same designations, rights, powers and preferences as the Class A common stock prior to the conversion. In addition, holders of our common stock vote as a single class of stock on any matter that is submitted to a vote of our stockholders. Prior to the conversion, the holders of our Class A and Class B common stock had identical voting rights, except that holders of Class A common stock were entitled to one vote per share and holders of Class B common stock were entitled to ten votes per share with respect to transactions that would result in a change of control of our company or that relate to our equity incentive plans. In addition, holders of Class B common stock had the exclusive right to elect two members of our Board of Directors, each referred to as a Class B Director. The shares of our Class B common stock were not publicly traded. Each share of our Class B common stock was convertible at any time at the option of the holder into one share of Class A common stock and in most instances automatically converted upon sale or other transfer.

On April 4, 2017, we consummated the transactions contemplated by a share and asset acquisition agreement with Marvell Semiconductor Inc., or Marvell, to purchase certain assets and assume certain liabilities of Marvell’s G.hn business, including its Spain legal entity, for aggregate cash consideration of $21.0 million. We also hired certain employees of the G.hn business outside of Spain and assumed employment obligations of the Spanish entity we acquired, which is now a subsidiary of MaxLinear. The assets acquired include, among other things, patents and other intellectual property, a workforce-in-place and other intangible assets, as well as tangible assets that include but are not limited to production masks and other production related assets, inventory and other property and equipment. The liabilities assumed include, among other things, product warranty obligations and accrued vacation and severance obligations for employees who joined MaxLinear and its subsidiaries as a result of the transaction. The acquired assets and assumed liabilities, together with the employees, represent a business as defined in ASC 805, Business Combinations. We integrated the acquired assets and employees into our existing business.

In April 2017, our subsidiary in Singapore began operating under certain tax incentives in Singapore, which are generally effective through March 2022 and may be extended through March 2027. Under these incentives, qualifying income derived from certain sales of our integrated circuits is taxed at a concessionary rate over the incentive period. We also receive a reduced withholding tax rate on certain intercompany royalty payments made by our Singapore subsidiary during the incentive period. Such incentives are conditional upon our meeting certain minimum employment and investment thresholds within Singapore over time, and we may be required to return certain tax benefits in the event the Company does not achieve compliance related to that incentive period. We currently believe that we will be able to satisfy these conditions without material risk. Primarily because of our Singapore net operating losses and our full valuation allowance in Singapore, we do not believe the incentives will have a material impact on our income tax position in the year ending December 31, 2018.

On May 12, 2017, pursuant to the March 28, 2017 Agreement and Plan of Merger, Eagle Acquisition Corporation, a Delaware corporation and wholly-owned subsidiary of MaxLinear, merged with and into Exar Corporation, or Exar, with Exar surviving as a wholly owned subsidiary of MaxLinear. Under this Agreement and Plan of Merger, we agreed to acquire Exar's outstanding common stock for $13.00 per share in cash. We also assumed certain of Exar's stock-based awards in the merger. We paid aggregate cash consideration of $688.1 million, including $12.7 million of cash paid to settle certain stock-based awards that were not assumed by us in the merger. We funded the transaction with cash from the balance sheet of the combined companies, including $235.8 million of cash from Exar, and the net proceeds of approximately $416.8 million under a secured term loan facility in an aggregate principal amount of $425.0 million. The facility is available (i) to finance the Merger, refinance certain existing indebtedness of Exar and its subsidiaries, and fund all related transactions, (ii) to pay fees and expenses incurred in connection therewith and (iii) for working capital and general corporate purposes. The term loan facility has a seven-year term and the term loans bear interest at either an Adjusted LIBOR or an Adjusted Base Rate, plus a fixed applicable margin. In November 2017, to hedge a substantial portion of our interest rate risk, we entered into a fixed-for-floating interest rate swap agreement with an amortizing notional amount to swap a substantial portion of our variable rate LIBOR interest payments under the outstanding term loans for fixed interest payments bearing an interest rate of 1.74685%. Our outstanding debt is still subject to a 2.5% fixed applicable margin during the term of the loan. As a result of entering the swap, the interest rate on a substantial portion of our long-term debt is effectively fixed at approximately 4.25%.

Exar is a designer and developer of high-performance analog mixed-signal integrated circuits and sub-system solutions. The merger significantly furthers our strategic goals of increasing revenue scale, diversifying revenues by end customers and addressable markets, and expanding our analog and mixed-signal footprint on existing tier-one customer platforms. Exar adds a diverse portfolio of high-performance analog and mixed-signal products constituting power management and interface technologies that are ubiquitous functions in wireless and wireline communications infrastructure, broadband access, industrial, enterprise networking, and automotive platforms. We intend to leverage combined technological expertise, cross-selling opportunities and distribution channels to significantly expand our serviceable addressable market. For a discussion of specific risks and uncertainties that could affect our ability to achieve these and other strategic objectives of our acquisitions, please refer to Part II, Item 1A, “Risk Factors” under the subsection captioned “Risks Relating to Our Recent Acquisitions.”

Critical Accounting Policies and Estimates

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

We believe that accounting policies we have identified as critical involve a greater degree of judgment and complexity than our other accounting policies. Accordingly, these are the policies we believe are the most critical to understanding and evaluating our consolidated financial condition and results of operations.

On January 1, 2018, we adopted Financial Accounting Standards Board, or FASB, Accounting Standards Codification Topic 606, Revenue from Contracts with Customers, or ASC 606, and accordingly, modified our policy on revenue recognition as stated below. The primary impact of adopting ASC 606 for MaxLinear was to accelerate the timing of our revenue and related cost recognition on products sold via some of our distributors, which changed from recognition upon the sale to our distributors' end customers, or the sell-through method, to recognition upon our sale to the distributor, or the sell-in method. We are now also required to estimate the effects of pricing credits to our distributors from contractual price protection and unit rebate provisions, as well as stock rotation rights and record such estimated credits upon our sale to the distributor.

There have been no other material changes to our critical accounting policies during the nine months endedSeptember 30, 2018.

For a summary of our other critical accounting policies and estimates, refer to Management's Discussion and Analysis section of our Annual Report on Form 10-K for the year ended December 31, 2017, which we filed with the Securities and Exchange Commission, or SEC, on February 20, 2018, or our Annual Report.

Revenue Recognition

Substantially all of our revenue is generated from sales of our integrated circuits to electronics distributors, module makers, OEMs, and ODMs under individual customer purchase orders, some of which have underlying master sales agreements that specify terms governing the product sales. Effective January 1, 2018, we adopted ASC 606 and recognize revenue at the point in time when control of the products is transferred to the customer at the estimated net consideration for which collection is probable, taking into account our customer's rights to price protection, other pricing credits, unit rebates, and rights to return unsold product. Transfer of control occurs either when products are shipped to or received by the distributor or direct customer, based on the terms of the specific agreement with the customer, if we have a present right to payment and transfer of legal title and the risks and rewards of ownership to the customer has occurred. For most of our product sales, transfer of control occurs upon shipment to our distributor or direct customer. In assessing whether collection of consideration from a customer is probable, the we consider the customer's ability and intention to pay that amount of consideration when it is due. Payment of invoices is due as specified in the underlying customer agreement, typically 30 days from the invoice date, which occurs on the date of transfer of control of the products to the customer. Since payment terms are less than a year, we have elected the practical expedient and do not assess whether a customer contract has a significant financing component.

A five-step approach is applied in the recognition of revenue under ASC 606: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when we satisfy a performance obligation. We applied ASC 606 to our customer contracts that were not completed before the January 1, 2018 adoption date. Customer purchase orders plus the underlying master sales agreements are considered to be contracts with the customer for purposes of applying the five-step approach under ASC 606.

Pricing adjustments and estimates of returns under contractual stock rotation rights are treated as variable consideration for purposes of determining the transaction price, and are estimated at the time control transfers using the expected value method based on our analysis of actual price adjustment claims by distributors and product and historical return rates, and then reassessed at the end of each reporting period. We also consider whether any variable consideration is constrained, since such

37

amounts for which it is probable that a significant reversal will occur when the contingency is subsequently resolved are required to be excluded from revenues. Price adjustments are finalized at the time the products are sold through to the end customer and the distributor or end customer submits a claim to reduce the sale price to a pre-approved net price. Stock rotation allowances are capped at a fixed percentage of our sales to a distributor for a period of time, up to six months, as specified in the individual distributor contract. If our current estimates of such credits and rights are materially inaccurate, it may result in adjustments that affect future revenues and gross profits. Returns under our general assurance warranty of products for a period of one to three years have not been material and warranty-related services are not considered a separate performance obligation under the customer contracts. Most of our customers resell our product as part of their product and thus are tax-exempt, however to the extent we collect and remit taxes on product sales from customers, we have elected to exclude from the measurement of transaction price such taxes.

Each distinct promise to transfer products is considered to be an identified performance obligation for which revenue is recognized upon transfer of control of the products to the customer. Although customers may place orders for products to be delivered on multiple dates that may be in different quarterly reporting periods, all of the orders are scheduled within one year from the order date. We have opted to not disclose the portion of revenues allocated to partially unsatisfied performance obligations, which represent products to be shipped within 12 months under open customer purchase orders, at the end of the current reporting period as allowed under ASC 606. We have also elected to record sales commissions when incurred, pursuant to the practical expedient under ASC 340, as the period over which the sales commission asset that would have been recognized is less than one year.

Customer contract liabilities consist of obligations to deliver rebates to customers in the form of units of products, which are included in accrued expenses and other current liabilities in the consolidated balance sheets. Other obligations to customers consist of estimates of price protection rights offered to our end customers, which are included in accrued price protection liability in the consolidated balance sheets, as well as price adjustments expected to be claimed by the distributor upon sell-through of the products to their customers, and amounts expected to be returned by distributors under stock rotation rights, which are included in accrued expenses and other current liabilities in the consolidated balance sheets. We also record a right of return asset consist of amounts representing the products we expect to receive from customers in returns, which is included in inventory in the consolidated balance sheets, and is typically settled within six months of transfer of control to the customer, or the period over which stock rotation rights are based. Upon lapse of the time period for stock rotations, or the contractual end to price protection and rebate programs, which is approximately one to two years, and when we believe unclaimed amounts are no longer subject to payment and will not be paid, any remaining asset or liability is derecognized by an offsetting entry to cost of net revenue and net revenue. For additional disclosures regarding contract liabilities and other obligations to customers, see Note 12 to our consolidated financial statements.

We assess customer accounts receivable and contract assets for impairment in accordance with ASC 310-10-35.

The impacts of adopting ASC 606 as shown above were primarily related to the acceleration of the timing of the Company’s revenue and related cost recognition on products sold via some of its distributors, which changed from sale to the distributors' end customers, or the sell-through method, to recognition upon the Company's sale to the distributor, or the sell-in method.

Revenues from sales through our distributors accounted for 46% and 41% of net revenue for the three months endedSeptember 30, 2018 and 2017, respectively. Revenues from sales through our distributors accounted for 41% and 31% of net revenue for the nine months ended September 30, 2018 and 2017, respectively.

Recently Adopted Accounting Pronouncements

In May 2014, the FASB, issued Accounting Standards Update, or ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which provides for new accounting guidance related to revenue recognition. This new standard replaced all prior U.S. GAAP guidance on this topic and eliminated 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 became effective for MaxLinear on January 1, 2018 and can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. We applied the guidance prospectively with an adjustment to

39

accumulated deficit for the cumulative effect of adoption. Adoption of the amendments in this guidance accelerated the timing of our revenue and related cost recognition on products sold via some distributors, which changed from the sell-through method to the sell-in method under this guidance. We are also required to estimate the effects of pricing credits to our distributors from contractual price protection and unit rebate provisions, as well as stock rotation rights. We have performed an assessment of the impact of adopting this new accounting standard on our consolidated financial position and results of operations. The impact of adoption of this new accounting standard for the year ending December 31, 2018 will vary depending on the level of inventory remaining at December 31, 2018 at distributors for which we previously recognized revenue on a sell-through basis, and therefore could have a material impact on our revenues for the year ending December 31, 2018. The impact to retained earnings as of January 1, 2018 is not material. As a result of applying the guidance prospectively with an adjustment to retained earnings in our consolidated financial statements for the cumulative effect of adoption, revenues that would have been recognized on a sell-through basis for the amount of deferred revenue and profit remaining as of the adoption date will not be recognized in earnings for any period.

In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this update include, among other things, a requirement to (1) measure equity investments (except equity method investments) at fair value with changes in fair value recognized in net income, with an option to measure equity investments that do not have readily determinable fair values at cost minus any impairment plus or minus any changes resulting from observable price changes; previously changes in fair value were recognized in other comprehensive income, and (2) separately present financial assets and liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statement. The amendments in this update were effective for us beginning in the first quarter of fiscal year 2018. The adoption of the amendments in this update did not have a material impact on our consolidated financial position and results of operations for the three and nine months ended September 30, 2018.

In March 2016, the FASB issued ASU No. 2016-08, Principal versus Agent Considerations (Reporting Revenue Gross versus Net) to clarify the revenue recognition implementation guidance on principal versus agent considerations. The amendments in this update clarify that when another party is involved in providing goods or services to a customer, an entity that is the principal has obtained control of a good or service before it is transferred to a customer, and provides indicators to assist an entity in determining whether it controls a specified good or service prior to the transfer to the customer. An entity that is the principal recognizes revenue in the gross amount of consideration to which it expects to be entitled in exchange for the specified good or service transferred to the customer, whereas an agent recognizes revenue in the amount of any fee or commission to which it expects to be entitled in exchange for arranging for the specified good or service to be provided by the other party. The amendments in this update were effective for us beginning in the first quarter of fiscal year 2018, concurrent with and applied on the same basis as the new revenue recognition standard. The adoption of the amendments in this update did not have a material impact on our consolidated financial position and results of operations for the three and nine months ended September 30, 2018.

In August 2016, the FASB issued ASU No. 2016-15, Classification of Certain Cash Receipts and Cash Payments to eliminate the diversity in practice regarding the presentation and classification of certain cash receipts and cash payments, including, among other things, contingent consideration payments made following a business combination, proceeds from the settlement of insurance claims in the statement of cash flows, and debt prepayment or debt extinguishment costs. Cash payments not made soon after the acquisition date up to the amount of the contingent consideration liability recognized at the acquisition date should be classified as financing activities and any excess payments should be classified as operating activities, whereas cash payments made soon after the acquisition date to settle the contingent consideration should be classified as investing activities and cash payments for debt prepayment or debt extinguishment costs should be classified as financing activities. Cash proceeds received from settlement of insurance claims should be classified on the basis of the nature of the related losses. The amendments in this update should be applied using a retrospective transition method to each period presented, unless impracticable, and if impracticable, would be applied prospectively as of the earliest date practicable. The amendments in this update were effective for us beginning in the first quarter of fiscal year 2018. The adoption of the amendments in this update did not have a material impact on our consolidated statements of cash flows for the three and nine months ended September 30, 2018.

In May 2017, the FASB issued ASU No. 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting to provide clarity and reduce both (1) diversity in practice and (2) cost and complexity when applying the guidance in Topic 718, Compensation—Stock Compensation, to a change to the terms or conditions of a share-based payment award. The amendments in this update require us to account for the effects of a modification in a stock-based award unless the fair value, vesting conditions and classification of the modified award is the same as those of the original award

40

immediately before the original award is modified. If the modification does not affect any of the inputs to the valuation technique that the entity uses to value the award, the entity is not required to estimate the value immediately before and after the modification. The amendments in this update were effective for us for fiscal years beginning with fiscal year 2018, including interim periods within those years, with early adoption permitted in any interim period. The amendments in this update are applied prospectively to an award modified on or after the adoption date. Since we have not had any modifications to stock-based awards that do not affect the inputs into the Black Scholes fair value calculation, the adoption of this guidance did not have a material impact on our consolidated financial position and results of operations for the three and nine months ended September 30, 2018.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act, or the Tax Act. The Tax Act makes broad and complex changes to the U.S. tax code. On December 22, 2017, the U.S. Securities and Exchange Commission Staff, or SEC Staff, issued guidance in Staff Accounting Bulletin No. 118, or SAB 118, to address certain fact patterns where the accounting for changes in tax laws or tax rates under ASC Topic 740 is incomplete upon issuance of an entity's financial statements for the reporting period in which the Tax Act is enacted. As permitted in SAB 118, in 2017, we took a measurement period approach and reported certain provisional amounts, based on reasonable estimates, for certain tax effects in which the accounting under ASC 740 is incomplete. Such provisional amounts are subject to adjustment during a limited measurement period, not to extend one year beyond the tax law enactment date, until the accounting under ASC 740 is complete. We also made required supplemental disclosures in the notes to the 2017 consolidated financial statements to accompany the provisional amounts, including the reasons for the incomplete accounting, the additional information or analysis that is needed, and other information relevant to why we were not able to complete the accounting required under ASC 740 in a timely manner. For adjustments to previously reported provisional amounts made in the three and nine months ended September 30, 2018, refer to Note 10. Additional adjustments to such reported provisional amounts could result in a material adverse impact to our consolidated financial position and results of operations in 2018.

In February 2018, the FASB issued ASU No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The amendments in this update allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Act. The amendments in this update are effective for us beginning in fiscal 2019, including interim periods. Early adoption is permitted. The amendments should be applied either in the period of adoption or retrospectively to each period or periods in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Act is recognized. We adopted the amendments in this update in the three months ended March 31, 2018. The adoption of this guidance did not have a material impact on our consolidated financial position and results of operations for the three and nine months ended September 30, 2018.

In March 2018, the FASB issued ASU No. 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118. The amendments in this update amend the SEC paragraphs included in Topic 740 to be consistent with the guidance in SAB 118, which we adopted in the three months ended December 31, 2017, as described above.

In June 2018, the FASB issued ASU No. 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, to expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. As a result, the accounting for share-based payment awards to nonemployees and employees will be substantially aligned by eliminating the need to measure nonemployee share-based awards at fair value on the earlier of performance commitment date or date performance is complete. Both employee and nonemployee share-based awards are now measured at grant-date fair value. The amendments in this update are effective for us beginning with fiscal year 2019, including interim periods, with early adoption permitted, but no earlier than our adoption of Topic 606. We elected to early adopt the amendments in this update as of July 1, 2018, with the cumulative effect of the change recorded against accumulated deficit as of July 1, 2018. As our nonemployee share-based awards are not significant, such adoption did not have a material impact on our consolidated accumulated deficit as of July 1, 2018.

Recently Issued Accounting Pronouncements

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The amendments in this update require a lessee to recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term for all leases with terms greater than twelve months. For leases less than twelve months, an entity is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognize lease expense for such leases

41

generally on a straight-line basis over the lease term. We intend to make this election. Also, in July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements, to provide an additional transition method. An entity can now elect not to present comparative financial information under Topic 842 if it recognizes a cumulative-effect adjustment to retained earnings upon adoption. We plan to elect this transition option in our adoption of Topic 842. The amendments in these updates are effective for us for fiscal years beginning with fiscal year 2019, including interim periods within those years, with early adoption permitted. We have performed a preliminary assessment of the impact of the adoption of the amendments in this update on our consolidated financial position and results of operations for our leases, which primarily consist of facility leases. Based on that assessment, we have determined that the right-of-use asset and lease liability, which is measured at the present value of future lease payments, are expected to have a material impact on our consolidated financial position. In addition, through the adoption date, we will complete the inventory of our leases and finalize our assessment of the impact of the adoption of Topic 842.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, to simplify the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. An entity no longer will determine goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if the reporting unit had been acquired in a business combination. Instead, under the amendments in this update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. The Board also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. The amendments in this update are effective for us beginning with fiscal year 2020, including interim periods, with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of the amendments in this update is not expected to have a material impact on our consolidated financial position and results of operations.

In July 2018, the FASB issued ASU No. 2018-09, Codification Improvements, to clarify the Codification and prevent any unintended applications of guidance. An amendment to ASC 718-740, Compensation—Stock Compensation—Income Taxes, clarifies that excess tax benefits should be recognized in the period in which the amount of the deduction is determined. The transition and effective date guidance is based on the facts and circumstances of each amendment. The amendment identified above is effective for us beginning with fiscal year 2019. The adoption of the amendments in this update is not expected to have a material impact on our consolidated financial position and results of operations.

In July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842, Leases, to clarify on how to apply certain aspects of the new leases standard. The amendments in this update, among other things, better articulates the requirement for a lessee's reassessment of lease classification as of the effective date of a modification, clarifies that a change to an index or rate for variable lease payments does not constitute a resolution of a contingency that would result in the remeasurement of lease payments, and requires entities that apply Topic 842 retrospectively to each reporting period and do not adopt the practical expedients to write off any prior unamortized initial direct costs that do not meet the definition under Topic 842 to equity. The amendments have the same effective date and transition requirements as the new lease standard summarized above. We are currently in the process of evaluating the impact of adoption of Topic 842 on our consolidated financial position and results of operations as stated above.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework— Changes to the Disclosure Requirements for Fair Value Measurement,to improve the fair value measurement reporting of financial instruments. The amendments in this update require, among other things, added disclosure of the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The amendments in this update eliminate, among other things, disclosure of the reasons for and amounts of transfers between Level 1 and Level 2 for assets and liabilities that are measured at fair value on a recurring basis and an entity's valuation processes for Level 3 fair value measurements. The amendments in this update will be effective for us beginning with fiscal year 2020, with early adoption permitted. Retrospective application is required for all amendments in this updated except the added disclosures, which should be applied prospectively. The adoption of the amendments in this update is not expected to have a material impact on our consolidated financial position and results of operations.

In August 2018, the FASB issued ASU No. 2018-15, Intangibles- Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract, to provide additional guidance on the accounting for costs of implementing cloud computing arrangements that are service contracts. The amendments in this update require the capitalization of implementation costs during the application

42

development stage of such hosting arrangements and amortization of the expense over the term of the arrangement including any option to extend reasonably certain to be exercised or option to terminate reasonably certain not to be exercised. Capitalized implementation costs and amortization thereof are also required to be classified in the same line item in the statements of financial position, operations and cash flows associated with the hosting service fees. The amendments in this update will be effective for us beginning with fiscal year 2020, with early adoption permitted. We may select retrospective or prospective application to all implementation costs incurred after the adoption date. The adoption of the amendments in this update is not expected to have a material impact on our consolidated financial position and results of operations.

Results of Operations

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

Net Revenue. Net revenue is generated from sales of radio-frequency, analog and mixed signal integrated circuits for the connected home, wired and wireless infrastructure, and industrial and multi-market applications. A significant portion of our sales are to distributors, who then resell our products.

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 acquired developed technology intangible assets and inventory step-ups to fair value; 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, amortization of certain acquired intangible assets, third-party sales commissions, field application engineering support, travel costs, professional and consulting fees, legal fees, depreciation expense and allocated occupancy costs.

Impairment Losses.  Impairment losses consist of charges resulting from the impairment of acquired intangible assets.

Restructuring Charges. Restructuring charges consist of severance, lease and leasehold impairment charges, and other charges related to restructuring plans.

Interest and Other Income (Expense), Net. Interest and other income (expense), net includes interest income, interest expense and other income (expense). Interest income consists of interest earned on our cash, cash equivalents and restricted cash balances. Interest expense consists of interest accrued on debt. Other income (expense) generally consists of income (expense) generated from non-operating transactions.

Income Tax Provision (Benefit). We make certain estimates and judgments in determining income taxes for financial statement purposes, including certain provisional estimates in the nine months ended September 30, 2018 for certain tax effects of the Tax Act for which accounting under ASC 740 is incomplete, as permitted under SAB 118. 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.

⁽¹⁾ Due to the adoption of ASC 606 using the modified retrospective method, prior period amounts have not been adjusted to reflect the change to recognize certain distributor sales upon sale to the distributor, or the sell-in method, from recognition upon the Company's sale to the distributors' end customers, or the sell-through method, which required the deferral of revenue and profit on such distributor sales. Refer to “Critical Accounting Policies and Estimates” section above for further details regarding the impact of this change in accounting.

Net revenue decreased$28.6 million to $85.0 million in the three months endedSeptember 30, 2018 from $113.6 million in the three months endedSeptember 30, 2017. The decrease in connected home net revenue of $23.6 million was primarily driven by a slowdown in the cable market owing to the market transition from DOCSIS 3.0 to DOCSIS 3.1 and related customer inventory reductions, which was partially offset by increased G.hn and satellite product shipments. Infrastructure revenue decreased$4.0 million, primarily related to declines in our high-speed interconnect products serving Chinese Metro market infrastructure build-outs and last-mile broadband access deployments in China. The decrease in industrial and multi-market net revenue of $1.0 million was primarily related to declines in touch module shipments serving the handset market.

Net revenue decreased$9.2 million to $297.4 million in the nine months ended September 30, 2018 from $306.6 million in the nine months ended September 30, 2017. The decrease in connected home net revenue of $57.9 million was driven by the anticipated declines from legacy product shipments used in satellite, terrestrial, and video SoC applications, as well as a slowdown in the cable market owing to the market transition from DOCSIS 3.0 to DOCSIS 3.1 and related customer inventory reductions, partially offset by increased G.hn product shipments. The increase in infrastructure revenues of $9.0 million was

44

primarily related to the incremental contribution of shipments from our power management and data encryption products acquired from Exar in May 2017 and increased wireless infrastructure shipments, which were partially offset by declines in our high-speed interconnect products serving the Chinese Metro market infrastructure build-outs and last-mile broadband access deployments in China. The increase in industrial and multi-market net revenue of $39.6 million was related to the incremental contribution of shipments from Exar.

⁽¹⁾ Due to the adoption of ASC 606 using the modified retrospective method, prior period amounts have not been adjusted to reflect the change to recognize cost of net revenue related to certain distributor sales upon sale to the distributor, or the sell-in method, from recognition upon the Company's sale to the distributors' end customers, or the sell-through method, which required the deferral of revenue and profit on such distributor sales. Refer to “Critical Accounting Policies and Estimates” section above for further details regarding the impact of this change in accounting.

Cost of net revenue decreased$20.6 million to $41.1 million in the three months endedSeptember 30, 2018 from $61.7 million in the three months endedSeptember 30, 2017. The decrease was primarily driven by lower sales and a decrease in amortization of inventory step-up of $10.2 million primarily related to the acquisition of Exar in May 2017 and the G.hn business acquired from Marvell in April 2017, partially offset by an increase in acquired intangible amortization of $1.1 million primarily related to these acquisitions. The gross profit percentage increased to 52% in the three months endedSeptember 30, 2018, as compared to 46% in the three months endedSeptember 30, 2017. The increase was primarily due to the decrease in acquired inventory step-up amortization.

Cost of net revenue decreased$16.2 million from $150.7 million in the nine months ended September 30, 2017 to $134.5 million in the nine months ended September 30, 2018. The decrease was primarily driven by lower sales and a decrease in amortization step-up of $15.8 million primarily related to recent acquisitions of Exar in May 2017 and the G.hn business acquired from Marvell in April 2017, partially offset by an increase in acquired intangible amortization of $10.1 million primarily related to these acquisitions. The gross profit percentage increased to 55% in the nine months ended September 30, 2018, as compared to 51% in the nine months ended September 30, 2017. The increase was primarily due to the decrease in acquired inventory step-up amortization.

We currently expect that gross profit percentage will fluctuate in the future, from period-to-period, based on changes in product mix, average selling prices, and average manufacturing costs.

Research and Development

% of net revenue	34		%	26		%						30		%	27		%

Research and development expense decreased$0.2 million from $29.3 million in the three months endedSeptember 30, 2017 to $29.0 million in the three months endedSeptember 30, 2018. The decrease was primarily due to lower payroll related expenses of $0.3 million and lower depreciation expense of $0.5 million as certain fixed assets reached the end of their useful lives. This decrease was partially offset by an increase in prototype expense of $0.5 million for new projects in the 2018 period.

45

Research and development expense increased$8.2 million from $82.2 million in the nine months ended September 30, 2017 to $90.4 million in the nine months ended September 30, 2018. The increase was primarily due to higher payroll-related expenses of $4.0 million related to the acquisitions in 2017 and higher prototype expenses of $3.7 million for new projects in the 2018 period. In addition, occupancy expenses were higher by $1.0 million partially due to new office leases in the current year as well as leases assumed in the 2017 acquisitions. The increase was partially offset by a decrease in depreciation expense of $0.6 million as certain fixed assets reached the end of their useful lives.

We expect our research and development expenses to increase in the future when we continue to focus on expanding our product portfolio and enhancing existing products.

Selling, General and Administrative

% of net revenue	29		%	26		%						26		%	26		%

Selling, general and administrative expense decreased$4.1 million from $29.0 million in the three months endedSeptember 30, 2017, to $25.0 million in the three months endedSeptember 30, 2018. The decrease was primarily due to decreases in intangible amortization expense of $1.9 million as the backlog from the Exar and G.hn business acquisitions existing at the acquisition dates has reached the end of its useful life, professional fees of $1.2 million related to merger and acquisition expenses in the prior year and sales commission expense of $0.4 million.

Selling, general and administrative expense decreased$2.4 million from $79.0 million in the nine months ended September 30, 2017 to $76.6 million in the nine months ended September 30, 2018. The decrease was primarily due to decreases in professional fees of $9.6 million related to merger and acquisition expenses in the prior year, commission expense of $1.4 million, and depreciation of $0.3 million. These decreases were partially offset by an increase in payroll-related expenses of $4.9 million and intangible asset amortization of $3.9 million mainly related to the acquisitions in the prior year.

We expect selling, general and administrative expenses to decrease or remain flat in the near-term; however, our expenses may increase in the future when we expand our sales and marketing organization to enable expansion into existing and new markets.

Restructuring charges decreased$1.9 million from $2.2 million in the three months endedSeptember 30, 2017 to $0.2 million in the three months endedSeptember 30, 2017. The charges in the three months endedSeptember 30, 2018 primarily consisted of severance-related charges of $0.4 million in connection with employee separation expenses, partially offset by $0.2 million in lease-related credits from adjustments to the net present value of our remaining lease obligation on the cease-use date for facilities we exited last year. The charges in the three months endedSeptember 30, 2017 consisted of severance-related charges of $1.7 million in connection with employee separation expenses and $0.5 million in lease-related and other charges from exiting certain facilities.

Restructuring charges decreased$6.6 million from $8.7 million in the nine months ended September 30, 2017 to $2.1 million in the nine months ended September 30, 2018. The charges in the nine months ended September 30, 2018 primarily consisted of severance-related charges of $0.7 million in connection with employee separation expenses and $1.3 million in lease-related charges from exiting certain facilities, including $0.7 million in impairment of leasehold improvements. In the nine months ended September 30, 2017, the charges primarily consisted of $4.9 million of incremental stock-based compensation from the acceleration of certain stock-based awards we assumed from Exar Corporation due to change in control provisions upon termination or diminution of authority of former Exar executives, other severance-related charges of $2.8 million, and lease restructuring charges of $0.9 million related to exiting certain Exar facilities.

Interest and other expense, net decreased by $1.4 million from $4.8 million in the three months endedSeptember 30, 2017 to $3.4 million in the three months endedSeptember 30, 2018. The decrease was primarily due to a decrease in interest expense of $0.7 million from a lower outstanding debt balance under the Exar acquisition term loan facility as a result of our repayments of principal. The remaining decrease of $0.7 million was primarily due to fluctuations in foreign currency transactions.

Interest and other expense, net increased by $3.3 million from $7.5 million in the nine months endedSeptember 30, 2017 to $10.8 million in the nine months endedSeptember 30, 2018. The increase was primarily due to an increase in interest expense of $4.7 million due to a full period of outstanding debt balance in the 2018 period compared to a partial period of outstanding debt balance in the 2017 period under the Exar acquisition term loan facility, which commenced in May 2017. The increase was partially offset by a decrease of $1.6 million primarily related to fluctuations in foreign currency transactions.

Income Tax Provision (Benefit)

% of net revenue	(2		)%	(6		)%						2		%	(11		)%

The income tax benefit in the three months endedSeptember 30, 2018 was $2.1 million compared to an income tax benefit of $6.3 million in the three months endedSeptember 30, 2017. The income tax provision in the nine months ended September 30, 2018 was $7.3 million compared to an income tax benefit of $33.8 million in the nine months ended September 30, 2017.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act, or the Tax Act, which included the reduction of the U.S. federal corporate tax rate from 35% to 21%. Additionally, in April 2017, our subsidiary in Singapore began operating under certain tax incentives in Singapore, which reduced our Singapore corporate tax rate from 17% to a concessionary rate as described in more detail below.

47

The income tax provision in the nine months ended September 30, 2018 primarily related to the mix of pre-tax income among jurisdictions, excess tax benefits related to stock-based compensation, and release of uncertain tax positions under ASC 740-10.

The income tax benefit in the nine months endedSeptember 30, 2017 primarily related to the release of the federal valuation allowance during the three months ended June 30, 2017.

We continue to maintain a valuation allowance to offset state and certain foreign deferred tax assets, as realization of such assets does not meet the more-likely-than-not threshold required under accounting guidelines. In making such determination, we consider all available positive and negative evidence quarterly, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and recent financial performance.  Based upon our review of all positive and negative evidence, as of September 30, 2018, and our provision estimates for the effects of the Tax Act, we concluded that a valuation allowance should continue to be recorded against our state deferred tax assets, certain federal deferred tax assets, and deferred tax assets in certain foreign jurisdictions where we have cumulative losses or otherwise are not expected to utilize certain tax attributes. We are closely assessing the need for a valuation allowance on the deferred tax assets by evaluating positive and negative evidence that may exist. In the future, we could remove some or all of the valuation allowance against our state and certain federal and foreign deferred tax assets if we meet the more-likely-than-not threshold at such time.

In the quarter ended June 30, 2017, our subsidiary in Singapore began operating under certain tax incentives in Singapore, which are generally effective through March 2022 and may be extended through March 2027. Under these incentives, qualifying income derived from certain sales of our integrated circuits is taxed at a concessionary rate over the incentive period. We also receive a reduced withholding tax rate on certain intercompany royalty payments made by our Singapore subsidiary during the incentive period. Such incentives are conditional upon our meeting certain minimum employment and investment thresholds within Singapore over time, and we may be required to return certain tax benefits in the event we do not achieve compliance related to that incentive period. We currently believe that we will be able to satisfy these conditions without material risk. Primarily because of our Singapore net operating losses and our full valuation allowance in Singapore, we do not believe the incentives will have a material impact on our income tax position in the year ending December 31, 2018.

Liquidity and Capital Resources

As of September 30, 2018, we had cash and cash equivalents of $67.2 million, restricted cash of $1.1 million and net accounts receivable of $58.6 million. Additionally, as of September 30, 2018, our working capital was $107.8 million.

Our primary uses of cash are to fund operating expenses, purchases of inventory, property and equipment and intangible assets. We also use cash to pay down outstanding debt. Our cash and cash equivalents are impacted by the timing of when we pay expenses as reflected in the change in our outstanding accounts payable and accrued expenses. Cash used to fund operating expenses in our consolidated statements of cash flows excludes the impact of non-cash items such as stock-based compensation, amortization and depreciation of acquired intangible assets and property and equipment, and impairment of intangible assets. Cash used to fund capital purchases is included in investing activities in our consolidated statements of cash flows. Cash used to pay down outstanding debt is included in financing activities in our consolidated statements of cash flows.

Our primary sources of cash are cash receipts on accounts receivable from our shipment of products to distributors and direct customers. Aside from the amounts billed to our customers, net cash collections of accounts receivable are impacted by the efficiency of our cash collections process, which can vary from period to period depending on the payment cycles of our major distributor customers, and relative linearity of shipments period-to-period. Our credit agreement, under which we entered into a term loan to partially fund our acquisition of Exar, permits us to request incremental loans in an aggregate principal amount not to exceed the sum of $160.0 million (subject to adjustments for any voluntary prepayments), plus an unlimited amount that is subject to pro forma compliance with certain secured leverage ratio and total leverage ratio tests. We have not requested any incremental loans to date.

Cash Flows from Operating Activities

Net cash provided by operating activities was $78.5 million for the nine months ended September 30, 2018. Net cash provided by operating activities for this period primarily consisted of positive cash flow from $86.8 million in non-cash operating expenses and $22.7 million in changes in operating assets and liabilities, partially offset by a net loss of $26.5 million, $3.3 million in deferred income taxes, and $1.2 million in excess tax benefits on stock-based awards. Non-cash operating expense items included in net loss for the nine months ended September 30, 2018 primarily consisted of depreciation and amortization of property, equipment, and acquired intangible assets of $59.9 million, stock-based compensation of $23.7 million, and impairment of intangible assets of $2.2 million.

Net cash provided by operating activities was $53.3 million for the nine months ended September 30, 2017. Net cash provided by operating activities for this period primarily consisted of net income of $10.3 million, $91.4 million in non-cash operating expenses, and $6.6 million in changes in operating assets and liabilities, partially offset by $48.4 million in deferred income taxes which primarily related to the release of the U.S. federal valuation allowance during the quarter ended June 30, 2017 and by $6.6 million in excess tax benefits on stock-based awards. Non-cash operating expenses included in net income for the nine months ended September 30, 2017 primarily included depreciation and amortization expense of property and equipment and acquired intangible assets of $46.5 million, stock-based compensation of $24.9 million, and amortization of inventory step-ups to fair value of $15.8 million, impairment of IPR&D assets of $2.0 million and losses on foreign currency of $1.4 million. Net income for the nine months ended September 30, 2017 excludes revenue of $5.2 million and gross profit of $3.9 million that would have been recorded by Exar on a sell-through basis had deferred revenue and deferred profit as of the May 12, 2017 acquisition date not been eliminated in the purchase price allocation of Exar as a result of acquisition accounting.

Cash Flows from Investing Activities

Net cash used in investing activities was $6.4 million for the nine months ended September 30, 2018. Net cash used in investing activities for this period consisted entirely of purchases of property and equipment.

Net cash used in investing activities was $429.1 million for the nine months ended September 30, 2017. Net cash used in investing activities for this period consisted primarily of $452.3 million in cash used in the acquisition of Exar, net of cash acquired, $21.0 million in cash used in the acquisition of the G.hn business, $30.6 million in purchases of securities, $5.4 million in purchases of intangible assets and $4.4 million in purchases of property and equipment, partially offset by $84.5 million in sales and maturities of securities.

49

Cash Flows from Financing Activities

Net cash used in financing activities was $78.9 million for the nine months ended September 30, 2018, and consisted primarily of cash outflows from aggregate prepayments of principal of $78.0 million on outstanding debt and $5.0 million in minimum tax withholding paid on behalf of employees related to vesting of restricted stock units and issuance of stock for bonus awards, partially offset by cash inflows from $4.1 million in net proceeds from issuance of common stock.

Net cash provided by financing activities was $365.8 million for the nine months ended September 30, 2017, and consisted primarily of $416.8 million in net proceeds from borrowings under a term loan we entered in connection with the acquisition of Exar and $9.1 million in net proceeds from issuance of common stock, partially offset by aggregate prepayments of principal of $50.0 million on outstanding debt and $9.8 million in minimum tax withholding paid on behalf of employees related to vesting of restricted stock units and issuance of stock for bonus awards.

We believe that our $67.2 million of cash and cash equivalents at September 30, 2018 will be sufficient to fund our projected operating requirements for at least the next twelve months. We have repaid $148.0 million of Exar-related transaction debt to date. The credit agreement permits the Company to request incremental loans in an aggregate principal amount not to exceed the sum of $160.0 million (subject to adjustments for any voluntary prepayments), plus an unlimited amount that is subject to pro forma compliance with certain secured leverage ratio and total leverage ratio tests. Incremental loans are subject to certain additional conditions, including obtaining additional commitments from the lenders then party to the credit agreement or new lenders. The term loan facility has a seven-year term and bears interest at either an Adjusted LIBOR or an Adjusted Base Rate, at our option, plus a fixed applicable margin.

Our cash and cash equivalents in recent years have been favorably affected by our implementation of an equity-based bonus program for our employees, including executives. In connection with that bonus program, in February 2018, we issued 0.3 million freely-tradable shares of our common stock in settlement of bonus awards for the 2017 performance period. We expect to implement a similar equity-based plan for fiscal 2018, 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 fund strategic initiatives or operating activities, particularly if we continue to pursue acquisitions. 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.

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, 2018, we were not involved in any unconsolidated SPE transactions.

Contractual Obligations

As of September 30, 2018, future minimum payments under long-term debt, non-cancelable operating leases, inventory purchase obligations, and other obligations are as follows:

	Payments due by Period
	Total		Less than 1 year		1-3 years		3-5 years		More than 5 Years

Other obligations consist of contractual payments due for software licenses.

Our contractual obligations including long-term debt, leases, inventory purchase obligations and other obligations, decreased by $86.3 million to $365.5 million as of September 30, 2018, from $451.8 million as of December 31, 2017 primarily as a result of prepayments of debt and contractual payments made on our operating leases, software licenses and outstanding inventory orders during the period, partially offset by an increase in inventory orders outstanding with our vendors and software licensing.

Other than disclosed above, there have been no other material changes during the nine months ended September 30, 2018 to our contractual obligations disclosed in our “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report on Form 10-K for the year ended December 31, 2017.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily a result of fluctuations in foreign currency exchange rates and interest rates. We do not hold or issue financial instruments for trading purposes.

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. A hypothetical change of 100 basis points in such foreign currency exchange rates would result in a change to translation gain/loss in accumulated other comprehensive income of approximately $0.3 million.

Interest Rate Risk

On May 12, 2017, we entered into a credit agreement with certain lenders and a collateral agent in connection with the acquisition of Exar. The credit agreement provides for an initial secured term B loan facility (the “Initial Term Loan”) in an aggregate principal amount of $425.0 million. As of September 30, 2018, aggregate borrowings under the Initial Term Loan were $277.0 million. The credit agreement permits the Company to request incremental loans in an aggregate principal amount not to exceed the sum of $160.0 million (subject to adjustments for any voluntary prepayments), plus an unlimited amount that is subject to pro forma compliance with certain secured leverage ratio and total leverage ratio tests. Incremental loans are subject to certain additional conditions, including obtaining additional commitments from the lenders then party to the credit agreement or new lenders. The term loan facility has a seven-year term and bears interest at either an Adjusted LIBOR or an Adjusted Base Rate, at our option, and, in each case, plus a fixed applicable margin. In November 2017, to hedge a substantial portion of our existing interest rate risk with respect to the term loans, we entered into a fixed-for-floating interest rate swap agreement with an amortizing notional amount to swap some of our variable rate interest payments under our term loans for fixed interest payments bearing an interest rate of 1.74685% through October 2020. Our outstanding debt is still subject to a 2.5% fixed applicable margin during the term of the loan. As a result of entering the swap, the interest rate on a substantial portion of our long-term debt is effectively fixed at approximately 4.25%. However, interest rate trends are inherently difficult to predict and interest rates may significantly increase or decrease over a short period of time. Should interest rates trend below that of our fixed swap interest rate, we may pay higher interest expense than market and seek to terminate or modify the terms of the swap prior to its maturity which could result in termination or other fees. We are also still subject to a variable amount of interest on the principal balance in excess of the notional amount of the interest rate swap and could be adversely impacted by rising interest rates in the future. If LIBOR interest rates had increased by 10%, or 1000 basis points, during the three months ended September 30, 2018, the rate increase would have resulted in an immaterial increase to interest expense, due to a small unhedged portion of the loan balance during the period relative to the total loan balance.

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

An evaluation was performed under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, to determine whether any change in our internal control over financial reporting occurred during the fiscal quarter ended September 30, 2018 that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. On May 12, 2017, we completed the acquisition of Exar and, as of September 30, 2018, we have completed the integration of the processes, systems, and controls relating to Exar into our existing system of internal control over financial reporting in accordance with our integration plans. There were no other changes in our internal control over financial reporting identified in connection with the evaluation required by paragraph (d) of Rule 13a-15 or Rule 15d-15 of the Securities Exchange Act of 1934, as amended, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

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, or the District Court Litigation. In its complaint, CrestaTech alleged that we infringe U.S. Patent Nos. 7,075,585, or the '585 Patent and 7,265,792, or the '792 Patent. In addition to asking for compensatory damages, CrestaTech alleged willful infringement and sought a permanent injunction. CrestaTech also named 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, among others, us, Sharp, Sharp Electronics, and VIZIO, or 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. which are collectively referred to with us, Sharp and VIZIO as the Company Respondents. CrestaTech’s ITC complaint alleged 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 MaxLinear’s accused products that CrestaTech alleged infringe the same two patents asserted in the Delaware action. Through its ITC complaint, CrestaTech sought 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 sought 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 our television tuners or televisions containing such tuners.

On March 10, 2014, the court stayed the District Court Litigation pending resolution of the ITC Investigation.

On December 15, 2014, the ITC held a trial in the ITC Investigation. On February 27, 2015, the Administrative Law Judge, or the ALJ, issued a written Initial Determination, or 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 our television tuners and televisions incorporating those tuners manufactured and sold by certain customers infringe three claims of the ‘585 Patent (claims 10, 12 and 13), 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 ITC subsequently issued its opinion, which terminated its investigation. The opinion affirmed the findings of the ALJ 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 ALJ's finding of infringement with respect to the three claims of the '585 Patent that were not held to be invalid.

On November 30, 2015, CrestaTech filed an appeal of the ITC decision with the United States Court of Appeals for the Federal Circuit, or the Federal Circuit. On March 7, 2016, CrestaTech voluntarily dismissed its appeal, resulting in a final determination of the ITC Investigation in our favor.

In addition, we have filed four petitions for inter partes review, or IPR, by the US Patent Office, two for each of the CrestaTech patents asserted against us. The Patent Trial and Appeal Board, or the PTAB, did not institute two of these IPRs as being redundant to IPRs filed by another party that were already underway for the same CrestaTech patent. The remaining two petitions were instituted or instituted-in-part meaning, together with the IPRs filed by third parties, there were six IPR proceedings instituted involving the two CrestaTech patents asserted against us.

In October 2015, the PTAB issued final decisions in two of the six pending IPR proceedings (one for each of the two asserted patents), holding that all of the reviewed claims are unpatentable. Included in these decisions was one of the three claims of the ‘585 Patent (claim 10) mentioned above in connection with the ITC’s final decision. CrestaTech appealed the PTAB’s decisions at the Federal Circuit. On November 8, 2016, the Federal Circuit issued an opinion affirming the PTAB’s finding of unpatentability.

54

In August 2016, the PTAB issued final written decisions in the remaining four pending IPR proceedings (two for each of the asserted patents), holding that many of the reviewed claims - including the two remaining claims of the ‘585 Patent which the ITC held were infringed - are unpatentable. The parties have appealed the two decisions related to the ‘585 Patent; however, no appeals were filed as to the PTAB’s rulings for the ‘792 Patent. The Federal Circuit heard oral argument on these appeals on December 4, 2017. On December 7, the Federal Circuit issued a Rule 36 affirmance in one of the '585 appeals, affirming that the two remaining claims that the ITC had ruled were valid and infringed (claims 12 and 13) are unpatentable. On January 25, 2018, the Federal Circuit issued its ruling in the other ‘585 appeal, vacating the PTAB's ruling that certain claims were not unpatentable and remanding to the PTAB for further analysis of whether CrestaTech is estopped from arguing and/or has waived the right to argue whether six dependent claims are patentable.

As a result of these IPR decisions, all 13 claims that CrestaTech asserted against us in the ITC Investigation have been found to be unpatentable by the PTAB and the Federal Circuit.

On March 18, 2016, CrestaTech filed a petition for Chapter 7 bankruptcy in the Northern District of California. As a result of this proceeding, all rights in the CrestaTech asserted patents, including the right to control the pending litigation, were assigned to CF Crespe LLC, or CF Crespe. CF Crespe became the named party in the then-pending IPRs, Federal Circuit appeal and District Court Litigation.

In April 2017, the Delaware court continued the stay of the District Court Litigation per the parties’ request, pending resolution of the Federal Circuit appeals in the IPRs. On April 3, 2018, the District Court dismissed the District Court Litigation. While Crespe has subsequently suggested that this dismissal may have been in error, Crespe has taken no action to date to re-instate the case. Indeed, in its bankruptcy proceeding Crespe has stated that it “no longer has any valid patent claims that it is asserting in any of the proceedings purchased through the Sale Agreement,” which includes the District Court Litigation against us. In re Cresta Technology Corporation, Case No. 16-50808 (N.D. Cal. Bank. 2016) at Dkt. No. 270.

We cannot predict the outcome of the District Court Litigation, or the IPRs. Any adverse determination in the District Court Litigation could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Trango Systems, Inc. Litigation

On or about August 2, 2016, Trango Systems, Inc., or Trango, filed a complaint in the Superior Court of California, County of San Diego, Central Division, against defendants Broadcom Corporation, Inc., or Broadcom, and us, collectively, Defendants. Trango is a purchaser that alleges various fraud, breach of contract, and interference with economic relations claims in connection with the discontinuance of a chip line we acquired from Broadcom in 2016. Trango seeks unspecified general and special damages, pre-judgment interest, expenses and costs, attorneys’ fees, punitive damages, and unspecified injunctive and equitable relief. On June 23, 2017, the Court sustained our demurrer to each cause of action in the second amended complaint, filed on or about December 6, 2016. Trango filed its third amended complaint on or about July 13, 2017. On February 23, 2018, the Court sustained, in part, our demurrer, dismissing with prejudice the cause of action for breach of a written contract, and Trango voluntarily dismissed its cause of action for breach of an implied-in-fact contract. The remaining causes of action have been permitted to proceed. On March 15, 2018, Trango filed its fourth amended complaint. We filed our answer on April 17, 2018. Also, on April 17, Broadcom filed a cross-complaint against us, alleging causes of action for indemnity, contribution and apportionment, and declaratory relief. Broadcom voluntarily dismissed the cross-complaint on June 8, 2018. The trial date is set for May 10, 2019. We intend to vigorously defend against the lawsuit as it proceeds.

We cannot predict the outcome of the Trango Systems, Inc. litigation. Any adverse determination in the Trango Systems, Inc. litigation could have a material adverse effect on our business, financial condition, results of operations and cash flows.

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 CrestaTech and Trango litigation described above, we believe that there are no other currently pending litigation matters that, if determined adversely by us, would have a material effect on our business or that would not be covered by our existing liability insurance.

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. In addition to the other information set forth in this report, you should also consider the risk factors discussed in our Annual Report on Form 10-K, which we filed with the SEC on February 20, 2018, or Annual Report, together with all of the other information included in this Quarterly Report on Form 10-Q, the Annual Report, and in our other public filings, which could materially affect our business, financial condition or future results.

During 2017, we acquired the G.hn business of Marvell and Exar Corporation. For the risks relating to our recent acquisitions, please refer to the section of these risk factors captioned “Risks Relating to Our Recent Acquisitions.”

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 connected home, wired and wireless infrastructure, and broader industrial and communications analog and mixed-signal markets 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. We expect competition to increase and intensify as a result of industry consolidation and the resulting creation of larger semiconductor companies. Large semiconductor companies resulting from industry consolidation could enjoy substantial market power, which they could exert through, among other things, aggressive pricing that could adversely affect our customer relationships and revenues. In addition, we expect the internal resources of large, integrated original equipment manufacturers, or OEMs, may continue to 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 communications and industrial platforms, our competitors range from large, international merchant semiconductor companies offering a wide range of semiconductor products to smaller companies specializing in narrow markets, to internal or vertically integrated engineering groups within certain customers. Our primary merchant semiconductor competitors include Silicon Labs, NXP Semiconductors N.V., RDA Microelectronics, Inc., MediaTek, Inc., Broadcom Ltd, Rafael Microelectronics, Inc., Inphi Corporation, M/A-COM Technology Solutions Holdings, Inc., Semtech Corporation, Qorvo Inc., Texas Instruments, HiSilicon Technologies Co., Ltd., Analog Devices, Integrated Device Technology, Inc. (which entered into a definitive agreement to be acquired by Renesas Electronics Corporation), Renesas Electronics Corporation, Maxim Integrated Products, Inc., Monolithic Power Systems, Microchip Technology, Inc., Ambarella, Inc., and Infineon Technologies AG. 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 our current and target markets. 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 or platform partners that develop their own integrated circuit products. If we cannot offer an attractive solution for applications where our competitors offer more fully integrated products, we may lose significant market share to our competitors. Certain of our competitors have fully-integrated tuner/demodulator/video processing solutions targeting high-

56

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, and we compete with much larger analog and mixed-signal catalog competitors in the multi-market high-performance analog markets.

Our ability to compete successfully depends on factors 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 intense 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 undergoing 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. In addition, Exar's business is substantially dependent on distributor agreements.

For the three months endedSeptember 30, 2018, although none of our customers individually accounted for 10% or more of our net revenue, our ten largest customers accounted for 69% of our net revenue. For the nine months endedSeptember 30, 2018, one customer accounted for 21% of our net revenue, and our ten largest customers accounted for 63% of our net revenue. For the three months endedSeptember 30, 2017, one customer accounted for 26% of our net revenue, and our ten largest customers accounted for 58% of our net revenue. For the nine months endedSeptember 30, 2017, one customer accounted for 27% of our net revenue, and our ten largest customers accounted for 60% of our net revenue. We expect that our operating results for the foreseeable future will continue to show a substantial but declining percentage of sales on an annualized basis dependent on 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 receiver SOCs, and MoCA®, G.hn connectivity solutions and high-performance analog 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;

• 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; and

• technological changes in our markets could lead to substantial volatility in our revenues based on product transitions, and particularly in our broadband markets, we face risks based on changes in the way consumers are accessing and using broadband and cable services, which could affect operator demand for our products.

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 products 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.

Exar derived a substantial portion of its business from two distributors, and we anticipate that sales of our products through these distributors will continue to account for a significant portion of our revenues from sales of Exar's integrated

57

circuit products. In addition, Exar's agreements with these distributors provide protection against price reduction on their inventories of our products. The loss of either or both of these distributors could have a material adverse effect on our business and results of operations, and price reductions associated with their inventories of our products could have a substantial adverse effect on our operating results in the event of a dramatic decline in selling prices for these products.

A significant portion of our revenue is attributable to demand for our products in markets for connected home solutions, and development delays and consolidation trends among cable and satellite Pay-TV and broadband operators could adversely affect our future revenues and operating results.

In the three months endedSeptember 30, 2018 and 2017, revenue directly attributable to connected home applications accounted for approximately 49% and 58% of our net revenue, respectively. In the nine months endedSeptember 30, 2018 and 2017, revenue directly attributable to connected home applications accounted for approximately 55% and 72% of our net revenue, respectively. Delays in the development of, or unexpected developments in the connected home markets could have an adverse effect on order activity by original equipment manufacturers in these markets and, as a result, on our business, revenue, operating results and financial condition. In addition, consolidation trends among pay-TV and broadband operators may continue, which could have a material adverse effect on our future operating results and financial condition. Most recently, we experienced sharper than previously anticipated declines in our legacy video SoC revenues as a result of the acquisition of Time Warner Cable by Charter Communications.

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

We sell most of our products to manufacturers of cable broadband voice and data modems and gateways, pay-TV set-top boxes and gateways into cable and satellite operator markets, satellite outdoor units or LNB’s, optical modules for long-haul and metro telecommunications markets, and RF transceivers and modem solutions for wireless infrastructure markets. With the acquisition of Exar, we expanded our product offerings to include power management and interface technologies which are ubiquitous functions in new and existing markets such as wireless and wireline communications infrastructure, broadband access, industrial, enterprise network, and automotive applications. Our future revenue growth, if any, will depend in part on our ability to further penetrate into, and expand beyond, these markets with analog and mixed-signal solutions targeting the markets for high-speed optical interconnects for data center, metro, and long-haul optical modules, telecommunications wireless infrastructure, and cable DOCSIS 3.1 network infrastructure products. 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.

Broadband data modems and gateways and pay-TV and satellite set-top boxes and video gateways continue to represent our largest North American and European revenue generator. The North American and European pay-TV market is dominated by only a few OEMs, including Technicolor, Arris Group, Inc., Hitron Technologies, Inc., Compal Broadband Networks, Humax Co., Ltd., and Samsung Electronics Co., Ltd. These OEMs are large multinational corporations with substantial negotiating power relative to us and are undergoing significant consolidation. 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, Liberty Global plc, Spectrum, Sky (in which Comcast now has a controlling stake), AT&T 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 that 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, which we believe have provided us with a significant competitive advantage. In the three months endedSeptember 30, 2018 and 2017, our research and development expense was $29.0 million and $29.3 million, respectively. In the nine months endedSeptember 30, 2018 and 2017, our research and development expense was $90.4 million and $82.2 million, respectively. We continue to maintain or increase our research and development expenditures as part of our strategy of devoting focused

58

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 28nm and 16nm 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 that are the focus of our research and development expenditures will become commercially successful.

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

We have been experiencing significant growth in a short period of time. Our net revenue increased from approximately $300.4 million in 2015, to $387.8 million in 2016 and $420.3 million in 2017, in part due to acquisitions. Our net revenue for the nine months ended September 30, 2018 was $297.4 million. 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.

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 broadband RF receivers and RF receiver SoCs, physical medium devices for optical modules, RF transceiver and modem solutions for wireless infrastructure markets, and high-performance analog solutions may contain defects and bugs when they are first introduced or as new versions are released. Where any of our products, including legacy acquired products, contain defects or bugs, or have reliability, quality or compatibility problems, we may not be able to successfully correct these problems. Consequently, our reputation may be damaged and customers may be reluctant to buy our products, which could materially and adversely affect our ability to retain existing customers and attract new customers, and our financial results. In addition, these defects or bugs could interrupt or delay sales to our customers. If any of these problems are not found until after we have commenced commercial production of a new product (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.

59

Average selling prices of our products could decrease rapidly, which would 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. In particular, we believe that industry consolidation has provided a number of larger semiconductor companies with substantial market power, which has had an adverse impact on selling prices in some of our markets. 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. Our inability to do so would cause our revenue and gross margins to decline. In addition, under Exar's agreements with key distributors, we provide protection for reductions in selling prices of the distributors' inventory, which could have a significant adverse effect on our operating results if the selling prices for those products fell dramatically.

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 have settled in the past 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 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, or the District Court Litigation. In its complaint, CrestaTech alleged that we infringe U.S. Patent Nos. 7,075,585, or the ‘585 Patent and 7,265,792, or the ‘792 Patent. In addition to asking for

60

compensatory damages, CrestaTech alleged willful infringement and sought a permanent injunction. CrestaTech also named 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, among others, us, Sharp, Sharp Electronics, and VIZIO, or 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. which are collectively referred to with us, Sharp and VIZIO as the Company Respondents. CrestaTech’s ITC complaint alleged 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 MaxLinear’s accused products that CrestaTech alleged infringe the same two patents asserted in the Delaware action. Through its ITC complaint, CrestaTech sought 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 sought 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 our television tuners or televisions containing such tuners.

On March 10, 2014, the court stayed the District Court Litigation pending resolution of the ITC Investigation.

On December 15, 2014, the ITC held a trial in the ITC Investigation. On February 27, 2015, the Administrative Law Judge, or the ALJ, issued a written Initial Determination, or 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 our television tuners and televisions incorporating those tuners manufactured and sold by certain customers infringe three claims of the ‘585 Patent (claims 10, 12 and 13), 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 ITC subsequently issued its opinion, which terminated its investigation. The opinion affirmed the findings of the ALJ 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 ALJ's finding of infringement with respect to the three claims of the '585 Patent that were not held to be invalid.

On November 30, 2015, CrestaTech filed an appeal of the ITC decision with the United States Court of Appeals for the Federal Circuit, or the Federal Circuit. On March 7, 2016, CrestaTech voluntarily dismissed its appeal, resulting in a final determination of the ITC Investigation in our favor.

In addition, we have filed four petitions for inter partes review, or IPR, by the US Patent Office, two for each of the CrestaTech patents asserted against us. The Patent Trial and Appeal Board, or the PTAB, did not institute two of these IPRs as being redundant to IPRs filed by another party that were already underway for the same CrestaTech patent. The remaining two petitions were instituted or instituted-in-part meaning, together with the IPRs filed by third parties, there were six IPR proceedings instituted involving the two CrestaTech patents asserted against us.

In October 2015, the PTAB issued final decisions in two of the six pending IPR proceedings (one for each of the two asserted patents), holding that all of the reviewed claims are unpatentable. Included in these decisions was one of the three claims of the ‘585 Patent (claim 10) mentioned above in connection with the ITC’s final decision. CrestaTech appealed the PTAB’s decisions at the Federal Circuit. On November 8, 2016, the Federal Circuit issued an opinion affirming the PTAB’s finding of unpatentability.

In August 2016, the PTAB issued final written decisions in the remaining four pending IPR proceedings (two for each of the asserted patents), holding that many of the reviewed claims - including the two remaining claims of the ‘585 Patent which the ITC held were infringed - are unpatentable. The parties have appealed the two decisions related to the ‘585 Patent; however, no appeals were filed as to the PTAB’s rulings for the ‘792 Patent. The Federal Circuit heard oral argument on these appeals on December 4, 2017. On December 7, the Federal Circuit issued a Rule 36 affirmance in one of the ‘585 appeals, affirming that the two remaining claims that the ITC had ruled were valid and infringed (claims 12 and 13) are unpatentable. On January 25, 2018, the Federal Circuit issued its ruling in the other ‘585 appeal, vacating the PTAB's ruling that certain claims were not unpatenable and remanding to the PTAB for further analysis of whether CrestaTech is estopped from arguing and/or has waived the right to argue whether six dependent claims are patentable.

61

As a result of these IPR decisions, all 13 claims that CrestaTech asserted against us in the ITC Investigation have been found to be unpatentable by the PTAB and the Federal Circuit.

On March 18, 2016, CrestaTech filed a petition for Chapter 7 bankruptcy in the Northern District of California. As a result of this proceeding, all rights in the CrestaTech asserted patents, including the right to control the pending litigation, were assigned to CF Crespe LLC, or CF Crespe. CF Crespe became the named party in the then-pending IPRs, Federal Circuit appeal and District Court Litigation.

In April 2017, the Delaware court continued the stay of the District Court Litigation per the parties’ request, pending resolution of the Federal Circuit appeals in the IPR’s. On April 3, 2018, the District Court dismissed the District Court Litigation. While Crespe has subsequently suggested that this dismissal may have been in error, Crespe has taken no action to date to re-instate the case. Indeed, in its bankruptcy proceeding Crespe has stated that it “no longer has any valid patent claims that it is asserting in any of the proceedings purchased through the Sale Agreement,” which includes the District Court Litigation against us. [In re Cresta Technology Corporation, Case No. 16-50808 (N.D. Cal. Bank. 2016) at Dkt. No. 270.]

We cannot predict the outcome of the District Court Litigation, or the IPRs. Any adverse determination in the District Court Litigation could have a material adverse effect on our business, financial condition, results of operations, and cash flows.

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 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;

62

• 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 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.

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 portion of our products to customers through our distributors, who maintain their own inventories of our products. For the three months endedSeptember 30, 2018 and 2017, sales through distributors accounted for 46% and 41% of our net revenue, respectively. For the nine months endedSeptember 30, 2018 and 2017, sales through distributors accounted for 41% and 31% of our net revenue, respectively. Upon shipment of product to these distributors, title to the inventory transfers to the distributor and the distributor is invoiced, generally with 30 to 60 day terms. Distributor sales are also recognized upon shipment to the distributor and estimates of future pricing credits and/or stock rotation rights reduce revenue recognized to the net amount before the actual amounts are known. If our estimates of such credits and rights are

63

materially understated it could cause subsequent adjustments that negatively impact our revenues and gross profits in a future period.

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.

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 accurately or at all.

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

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

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. In addition, we have in the past and may in the future be subject to "phishing" attacks in which third parties send emails purporting to be from reputable companies in order to obtain personal information and infiltrate our systems to initiate wire transfers or otherwise obtain proprietary or confidential information. A number of large, public companies have recently experienced losses based on phishing attacks and other cyber-attacks. Any 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, cause us to incur direct losses if attackers access our bank or investment accounts, 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.

64

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.

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, including sole sourcing for many components or products. Currently, the majority of our products are manufactured by Global Foundries, Silan, Semiconductor Manufacturing International Corporation, or SMIC, Taiwan Semiconductor Manufacturing Corp, or TSMC, and United Microelectronics Corporation, or UMC, at foundries located in Taiwan, Singapore, 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 the majority of our fabrication and assembly and test contractors are all located in the Pacific Rim region, principally in China, Taiwan, and Singapore. 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 but, not limited to Global Foundries, Silan, SMIC, TSMC, and UMC. We make substantially all of our purchases on a purchase order basis, and our contract manufacturers are not 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

65

reallocation could impair our ability to secure the supply of components that we need. We generally place orders for products with some of our suppliers approximately four to five months prior to the anticipated delivery date, with order volumes based on our forecasts of demand from our customers. Accordingly, if we inaccurately forecast demand for our products, we may be unable to obtain adequate and cost-effective foundry or assembly capacity from our third-party contractors to meet our customers’ delivery requirements, or we may accumulate excess inventories. On occasion, we have been unable to adequately respond to unexpected increases in customer purchase orders and therefore were unable to benefit from this incremental demand. None of our third-party contractors has provided any assurance to us that adequate capacity will be available to us within the time required to meet additional demand for our products.

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, cable and satellite television, and broadband voice and data applications, and as part of our strategy, we seek to expand our addressable market into new product categories. For example, we previously expanded into the market for satellite set-top and gateway boxes and outdoor units and physical medium devices for the optical interconnect markets, and through the Broadcom and Microsemi business line acquisitions in 2016, we entered the markets for wireless telecommunications infrastructure. Through the acquisition of the G.hn business of Marvell in April 2017, we expanded into the wired whole-home broadband connectivity market. With our acquisition of Exar in May 2017, we also entered the markets for power management and interface technologies which are ubiquitous functions in wireless and wireline communications infrastructure, broadband access, industrial, enterprise network, and automotive applications. Our limited operating experience in these 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. 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.

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 attract and retain all of these personnel as we continue to pursue our business strategy. Historically, we have encountered difficulties in hiring and retaining qualified engineers because there is a limited pool of engineers with the expertise required in our field. Competition for these personnel is intense in the semiconductor industry. As the source of our technological and product innovations, our design and technical personnel represent a significant asset. In addition, two of our current executives, our chief financial officer and chief corporate strategy officer and our vice president of sales, joined us in July 2018. As new employees gain experience in their roles, we could experience inefficiencies or a lack of business continuity due to loss of historical knowledge and a lack of familiarity of new employees with business processes, operating requirements, policies and procedures, and we may experience additional costs as new employees gain necessary experience. It is important to our success that these key employees quickly adapt to and excel in their new roles. If they are unable to do so, our business and financial results could be materially adversely affected. 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. 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. We are fortunate that many members of our executive management team have long tenures with us, but from time to time we also have been required to recruit new executive officers. For example, two of our current executives, our chief financial officer and chief corporate strategy officer and our vice president of sales, joined us in July 2018. With respect to executive officer recruitment and retention, we need to ensure that our executive compensation programs provide sufficient recruitment and retention incentives as well as incentives to achieve our long-term strategic business and financial objectives. We expect competition for individuals with our required skill sets, particularly technical and engineering skills, to remain intense even in weak global macroeconomic environments. 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 our solutions, or 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.

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 and G.hn SoCs, DBS-ODU SoCs, physical medium devices for optical modules, interface and power management devices, and SoC solutions targeting infrastructure opportunities within the telecommunications, wireless, industrial and multimarket and broadband operator markets 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 18-24 months for the satellite markets, and 36 months or longer for industrial, wired and wireless infrastructure markets. The delays inherent in these lengthy sales cycles increase the risk that a customer will decide to cancel, curtail, reduce or delay its product plans, causing us to lose anticipated sales. In addition, any delay or cancellation of a customer’s plans could materially and adversely affect our financial results, as we may have incurred significant expense and generated no revenue. Finally, our customers’ failure to successfully market and sell their products could reduce demand for our products and materially and adversely affect our business, financial condition and results of operations. If we were unable to generate revenue after incurring substantial expenses to develop any of our products, our business would suffer.

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

Our revenue and operating results have fluctuated in the past and are likely to fluctuate in the future. These fluctuations may occur on a quarterly and on an annual basis and are due to a number of factors, many of which are beyond our control. These factors include, among others:

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

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

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

• the gain or loss of significant customers;

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

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

67

• 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.

These 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 all of our products. 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.

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.

68

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.

We are subject to income taxes in the United States, Singapore and various other foreign jurisdictions. The amount of income taxes we pay is subject to our interpretation and application of tax laws in jurisdictions in which we file. Changes in current or future laws or regulations, the imposition of new or changed tax laws or regulations or new interpretations by taxing authorities or courts could affect our results of operations and lead to volatility with respect tax expenses and liabilities from period to period. The application of 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. Furthermore, such material adverse impact may extend beyond one fiscal year. For example, on December 22, 2017, the Tax Cuts and Jobs Act, or the Tax Act, was enacted into U.S. tax law. Also on December 22, 2017, the SEC issued guidance in Staff Accounting Bulletin No. 118, or SAB 118, to address certain fact patterns where the accounting for changes in tax laws or tax rates under ASC Topic 740 is incomplete upon issuance of an entity's financial statements for the reporting period in which the Tax Act is enacted. As permitted in SAB 118, in 2017 and in the three and nine months endedSeptember 30, 2018, we have taken a measurement period approach and reported certain provisional amounts, based on reasonable estimates, for certain tax effects in which the accounting under ASC 740 is incomplete. Such provisional amounts are subject to adjustment during a limited measurement period, not to extend one year beyond the tax law enactment date, until the accounting under ASC 740 is complete. We also made required supplemental disclosures to accompany the provisional amounts, including the reasons for the incomplete accounting, the additional information or analysis that is needed, and other information relevant to why the registrant was not able to complete the accounting required under ASC 740 in a timely manner. Adjustments to such reported provisional amounts could result in a material adverse impact on our net income and our financial position in fiscal 2018.

We are subject to examinations and tax audits. There can be no assurance that the outcome from these audits will not have an adverse effect on our operating results or financial position.

69

We adopted amendments to U.S. generally accepted accounting principles related to stock-based compensation in the second quarter of 2016 and included excess tax benefits associated with employee stock-based compensation in income tax expense. However, since the amount of such excess tax benefits and deficiencies depend on the fair market value of our common stock, our income tax provision is subject to volatility in our stock price and in the future, could unfavorably affect our future effective tax rate.

Our future effective tax rate could be unfavorably affected by unanticipated changes in the valuation of our deferred tax assets and liabilities, and the ultimate use and depletion of these various tax credits and net operating loss carryforwards. Changes in our effective tax rate, including those from enactment of the Tax Act in 2017, 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 making such determination, the Company considers all available positive and negative evidence quarterly, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and recent financial performance. To the extent we believe it is more likely than not that some portion of our deferred tax assets will not be realized, we record a valuation allowance against the deferred tax asset. Realization of our deferred tax assets is dependent primarily upon future taxable income in the applicable jurisdiction. During the quarter ended June 30, 2017, we released the valuation allowance against U.S. federal deferred tax assets. Based upon our review of all positive and negative evidence, we concluded that a full valuation allowance should continue to be recorded against our state and certain foreign net deferred tax assets at September 30, 2018. On a periodic basis we evaluate our deferred tax assets for realizability. The impact of releasing some or all of such valuation allowance in a future period could be material in the period in which such release occurs.

Our corporate income tax liability could materially increase if tax incentives we have negotiated in Singapore cease to be effective or applicable or if we are challenged on our use of such incentives.

Effective in the second quarter of 2017, we began to operate under certain favorable tax incentives in Singapore which are effective through March 2022 and may be extended through March 2027, and generally are dependent on our meeting certain headcount and investment thresholds. Such incentives allow certain qualifying income earned in Singapore to be taxed at reduced rates and are conditional upon our meeting certain employment and investment thresholds over time. If we fail to satisfy the conditions for receipt of these tax incentives, or to the extent US or other tax authorities challenge our operation under these favorable tax incentive programs or our intercompany transfer pricing agreements, our taxable income could be taxed at higher federal or foreign statutory rates and our income tax liability and expense could materially increase beyond our projections. Each of our Singapore tax incentives is separate and distinct from the others, and may be granted, withheld, extended, modified, truncated, complied with or terminated independently without any effect on the other incentives. Absent these tax incentives, our corporate income tax rate in Singapore is expected to be the 17% statutory tax rate. We are also subject to operating and other compliance requirements to maintain our favorable tax incentives. If we fail to comply with such requirements, we could lose the tax benefits and could possibly be required to refund previously realized material tax benefits. Additionally, in the future, we may fail to qualify for renewal of our favorable tax incentives or such incentives may not be available to us, which could also cause our future taxable income to increase and be taxed at higher statutory rates. Loss of one more of our tax incentives could cause us to modify our tax strategies and our operational structure, which could cause disruption in our business and have a material adverse impact on our results of operations. Further, there can be no guarantee that such modification in our tax strategy will yield tax incentives as favorable as those we have negotiated with Singapore. Our interpretations and conclusions regarding the tax incentives are not binding on any taxing authority, and if our assumptions about tax and other laws are incorrect or if these tax incentives are substantially modified or rescinded we could suffer material adverse tax and other financial consequences, which would increase our expenses, reduce our profitability and adversely affect our cash flows.

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 such products will ultimately be driven by consumer demand for products such as televisions, personal computers, automobiles, cable modems, smartphones, 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,

70

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.

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 81% and 86% of our net revenue in the three months endedSeptember 30, 2018 and 2017, respectively. Products shipped to Asia accounted for 81% and 90% of our net revenue in the nine months endedSeptember 30, 2018 and 2017, respectively. In addition, approximately 50% of our employees are located outside of the United States as of September 30, 2018. The majority 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 Taiwan, Singapore, and China, substantially all of our products undergo packaging and final testing in Taiwan, Singapore, China, South Korea, and Thailand. Any conflict or uncertainty in these countries, 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. Similarly, we ceased business operations with entities affiliated with ZTE Corp. when the Bureau of Industry and Security at the U.S. Department of Commerce imposed an export licensing requirement, which was subsequently suspended through March 28, 2017. Such suspension was lifted as of March 29, 2017, however on April 17, 2018 the U.S. Department of Commerce imposed a seven-year export ban on ZTE, which was subsequently lifted as of

71

July 13, 2018. Although we do not have significant sales to ZTE, we cannot provide assurances that similar disruptions in the future of distribution arrangements or the imposition of governmental prohibitions on selling our products to particular customers will not adversely affect our revenues and operating results. Loss of a key distributor or customer under similar circumstances could have an adverse effect on our business, revenues and operating results.

Changes in trade policies among the United States and other countries, in particular the imposition of new or higher tariffs, could place pressure on our average selling prices as our customers seek to offset the impact of increased tariffs on their own products. Increased tariffs or the imposition of other barriers to international trade could have a material adverse effect on our revenues and operating results.

In recent months, the United States has imposed or proposed new or higher tariffs on certain products exported by a number of U.S. trading partners, including China, Europe, Canada, and Mexico. In response, many of those trading partners, including China, have imposed or proposed new or higher tariffs on American products. Continuing changes in government trade policies create a heightened risk of further increased tariffs that impose barriers to international trade. Our business and operating results are substantially dependent on international trade, particularly involving the sale of our products into China. Approximately 62% of our total revenues in the nine months endedSeptember 30, 2018 consisted of sales of our integrated circuits to both Original Equipment Manufacturers (OEMs) and Ordinary Device Manufacturers (ODMs) in China. Many of these manufacturers sell products incorporating our semiconductors into other international markets, including the United States.

Tariffs on our customers’ products may adversely affect our gross profit margins in the future due to the potential for increased pressure on our selling prices by customers seeking to offset the impact of tariffs on their own products. In addition, tariffs could make our OEM and ODM customers’ products less attractive relative to products offered by their competitors, which may not be subject to similar tariffs. Some OEM and ODMs in our industry have already begun implementing short-term price adjustments to offset such tariffs and transitioning their production and supply chain to locations outside of China. We believe that increases in tariffs on imported goods or the failure to resolve current international trade disputes could have a material adverse effect on our business and operating results.

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, the Foreign Corrupt Practices Act, and other anticorruption laws. 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, as indicated elsewhere in this report, we do a substantial portion of our business in Asia and particularly in China. In recent years, there has been a substantial focus by regulators in the United States and Europe on the business practices of major Chinese technology companies such as Huawei and ZTE. Huawei and ZTE are each our current customers. While we intend to conduct our businesses in compliance with all applicable laws, including laws relating to export controls and anti-corruption, it is possible that the nature of our business and customers could result in a review of our relationships and practices by regulatory authorities. We could incur increased administrative and legal costs in order to respond to any inquiries, and any failure to comply with applicable laws could adversely affect our business and operating results. We have implemented policies and procedures, including adoption of an anti-corruption policy and procedures to ensure compliance with applicable export control laws, but there can be no assurance that these policies and procedures will prove effective.

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.

72

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 risk of an earthquake in the Pacific Rim region or Southern California is significant due to the proximity of major earthquake fault lines. 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. The majority of the factories we use for foundry, assembly and test, and warehousing services, are located in Asia. Our corporate headquarters is located in Southern California.

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 or parts 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 Common Stock

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

We use our cash and cash equivalents for general corporate purposes, including working capital and for repayment of outstanding long-term debt. 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 and cash equivalents, and 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 cash and cash equivalents for corporate purposes that do not increase our operating results or market value. In addition, in the future our cash and cash equivalents, and 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 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, or our President;

• 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;

• 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;

• 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 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, we have experienced limited trading volumes and liquidity in the past, and similar issues in the future could 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 common stock is sometimes modest relative to our total outstanding shares, and the price of our 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

74

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 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 the 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;

• 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 acquisitions may not be accretive and may cause dilution to our earnings per shares;

• announcement or expectation of additional financing efforts;

• sales of our 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 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 have been and may continue to 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, our share price and trading volume could decline.

The trading market for our common stock depends in part on the research and reports that securities or industry analysts publish about us or our business. 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.

75

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

Sales of a substantial number of shares of our common stock in the public market, or the perception that these sales might occur, could depress the market price of our common stock and could impair our ability to raise capital through the sale of additional equity securities. As of September 30, 2018, we had approximately 68.9 million shares of common stock outstanding.

All shares of common stock are freely tradable without restrictions or further registration under the Securities Act of 1933, as amended, or the Securities Act, unless held by our “affiliates,” as that term is defined under Rule 144 under the Securities Act, or Rule 144.

Our Executive Incentive Bonus Plan permits the settlement of awards under the plan in the form of shares of our common stock. We have issued shares of our common stock to settle such bonus awards for our employees, including executives, for the 2014 to 2017 performance periods, and we intend to continue this practice in the foreseeable future. We issued 0.3 million shares of our common stock for the 2017 performance period in February 2018. If we issue additional shares of our common stock to settle bonus awards in the future, such shares may be freely sold in the public market immediately following the issuance of such shares, subject to the applicable conditions of Rule 144 and our insider trading policy, 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 common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investments.

Risks Relating to Our Acquisitions

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

In addition to the acquisitions of Exar and the G.hn business of Marvell Technology Group Ltd., or Marvell, which we completed in the second quarter of fiscal 2017, we also acquired the wireless infrastructure backhaul business of Broadcom Corporation, which we completed in the third quarter of fiscal 2016, the wireless infrastructure access business of Microsemi Storage Solutions, Inc., formerly known as PMC-Sierra, Inc., which we completed in the second quarter of fiscal 2016, Entropic Communications, Inc., or Entropic, which we completed in the second quarter of fiscal 2015, and Physpeed, Co., Ltd., or 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;

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

• stockholder or other litigation relating to the transaction;

• adverse tax consequences; and

76

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

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 completed acquisitions, may be expensive, time-consuming, and a strain on our resources and our relationships with employees, customers, distributors, 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 businesses 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.

On or about August 2, 2016, Trango Systems, Inc., or Trango, filed a complaint in the Superior Court of California, County of San Diego, Central Division, against defendants Broadcom Corporation, Inc., or Broadcom, and us, collectively, Defendants. Trango is a purchaser that alleges various fraud, breach of contract, and interference with economic relations claims in connection with the discontinuance of a chip line we acquired from Broadcom in 2016. Trango seeks unspecified general and special damages, pre-judgment interest, expenses and costs, attorneys’ fees, punitive damages, and unspecified injunctive and equitable relief. On June 23, 2017, the Court sustained our demurrer to each cause of action in the second amended complaint, filed on or about December 6, 2016. Trango filed its third amended complaint on or about July 13, 2017. On February 23, 2018, the Court sustained, in part, our demurrer, dismissing with prejudice the cause of action for breach of a written contract, and Trango voluntarily dismissed its cause of action for breach of an implied-in-fact contract. The remaining causes of action have been permitted to proceed. On March 15, 2018, Trango filed its fourth amended complaint. We filed our answer on April 17, 2018. Also, on April 17, Broadcom filed a cross-complaint against us, alleging causes of action for indemnity, contribution and apportionment, and declaratory relief. Broadcom voluntarily dismissed the cross-complaint on June 8, 2018. The trial date is set for May 10, 2019. We intend to vigorously defend against the lawsuit as it proceeds.

We cannot predict the outcome of the Trango litigation. Any adverse determination in the Trango litigation could have a material adverse effect on our business, financial condition, results of operations and cash flows.

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

Our history of acquiring businesses is recent, and prior to our acquisition of Exar, we had never pursued an acquisition of that size and complexity. We may complete larger-scale acquisitions in the future. The success of our recent and future

77

acquisitions depends, in substantial part, on our ability to integrate acquired businesses and operations efficiently and 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; potential operational efficiencies in our respective supply chains and in research and development investments; and potential revenue growth resulting from the addition of acquired product portfolios. If we are unable to achieve these objectives, the anticipated benefits and potential synergies from the acquisitions may not be realized fully 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, and could also have a material and adverse effect on the trading price or trading volume of our common stock.

We completed acquisitions in April 2015, April 2016, July 2016, April 2017 and May 2017. We have completed the integration process for such acquisitions. We have incurred material restructuring costs in recent periods, some of which included employees from acquired businesses. To the extent we acquire additional businesses in the future, we cannot ensure that integration objectives will not adversely affect our operating results. In connection with the integration process, we could experience the loss of key customers, decreases in revenues relative to current expectations 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 acquisitions and have a material adverse effect on our business, operating results, and financial condition.

Our business relationships, including customer relationships, and those of our acquired businesses may be subject to disruption due to uncertainty associated with the acquisitions.

In response to the completion of our acquisitions, customers, vendors, licensors, and other third parties with whom we do business or the acquired entities did business or otherwise have relationships may experience uncertainty associated with the acquisitions, and this uncertainty could materially affect their decisions with respect to existing or future business relationships with us. 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 acquired products, or any general perceptions by customers or other third parties that impute operational or business challenges to us arising from the acquisitions. 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 common stock.

In connection with the acquisition of Exar, we incurred $425.0 million of secured term loan indebtedness. We have since entered into an interest rate swap to hedge a substantial portion of our exposure to rising interest rates applicable to such indebtedness. We had not previously carried long-term indebtedness, which will continue to adversely affect our operating results and cash-flows as we satisfy our underlying interest and principal payment obligations. Additionally, our interest rate swap has a declining notional amount based on our anticipated prepayment of indebtedness; therefore, if the unhedged portion of our indebtedness increases substantially at the same time interest rates increase, it could adversely affect our operating results and cash flows.

MaxLinear financed the acquisition of Exar in part with a secured term loan facility in an aggregate principal amount of approximately $425.0 million, of which $277.0 million remains outstanding as of September 30, 2018. In November 2017, to hedge most of our existing interest rate risk, we entered into a fixed-for-floating interest rate swap agreement with an amortizing notional amount to swap a substantial portion of our variable rate LIBOR interest payments under the outstanding term loans for fixed interest payments bearing an interest rate of 1.74685%. Our outstanding debt is still subject to a 2.5% fixed applicable margin during the term of the loan. As a result of entering the swap, the interest rate on a substantial portion of our long-term debt is effectively fixed at approximately 4.25%. The term loan facility is secured by a first priority security interest in MaxLinear’s assets, subject to certain customary exceptions, as well as pledges of our equity interests in certain subsidiaries. Prior to the Exar acquisition, we had not previously carried long-term debt on our balance sheet and had financed our operations principally through working capital generated from operations as well as sales and issuances of our equity securities. Our indebtedness will continue to adversely affect our operating expenses through interest payment obligations and will

78

continue to adversely affect our ability to use cash generated from operations as we repay interest and principal under the term loans. In addition, although the term loan provisions do not include financial covenants, they do include operational covenants that may adversely affect our ability to engage in certain activities, including certain financing and acquisition transactions, stock repurchases, guarantees, and similar transactions, without obtaining the consent of the lenders, which may or may not be forthcoming. Accordingly, outstanding indebtedness could adversely affect our operational freedom or ability to pursue strategic transactions that we would otherwise consider to be in the best interests of stockholders.

Specifically, our indebtedness could have important consequences to investors in our common stock, including the following:

• our ability to obtain any necessary financing in the future for working capital, capital expenditures, debt service requirements, or other purposes may be limited or financing may be unavailable;

• a substantial portion of our cash flows must be dedicated to the payment of principal and interest on our indebtedness and other obligations and will not be available for use in our business;

• our level of indebtedness could limit our flexibility in planning for, or reacting to, changes in our business and the markets in which we operate;

• our high degree of indebtedness will make us more vulnerable to changes in general economic conditions and/or a downturn in our business, thereby making it more difficult for us to satisfy our obligations;

• we are subject to a fixed rate of interest as a result of entering into a fixed-for-floating interest rate swap agreement in November 2017 to hedge against the potential that the interest rates applicable to our term loan will increase. Our interest rate under the term loan varies based on a fixed margin over either an adjusted LIBOR or an adjusted base rate. Interest rates, including LIBOR, have recently increased and may continue to increase in future periods. However, interest rate trends are inherently difficult to predict and interest rates may significantly increase or decrease over a short period of time. If interest rates were to decrease substantially, we would pay higher interest expense than market and, as a result, could seek to terminate or modify the terms of the swap prior to its maturity which could result in termination or other fees and the fair value of our interest rate swap may also decrease substantially; and

• we are also still subject to variable interest rate risk on the principal balance in excess of the notional amount of the interest rate swap because our interest rate under the term loan varies based on a fixed margin over either an adjusted LIBOR or an adjusted base rate. Interest rates, including LIBOR, have recently increased and may continue to increase in future periods. If we are unable to make anticipated prepayments of our indebtedness causing the unhedged portion of our indebtedness to subtantially increase at the same time that interest rates were to increase substantially, it would adversely affect our operating results and could affect our ability to service the term loan indebtedness.

If we fail to make required debt payments, or if we fail to comply with other covenants in our debt service agreements, we would be in default under the terms of these agreements. Subject to customary cure rights, any default would permit the holders of the indebtedness to accelerate repayment of this debt and could cause defaults under other indebtedness that we have, any of which could have a material adverse effect on the trading price of our common stock.

Servicing our indebtedness will require a significant amount of cash, and we may not have sufficient cash flow from our business to pay our substantial indebtedness.

In connection with the term loan facility, we incurred $425.0 million in aggregate principal amount of senior indebtedness, of which approximately $277.0 million remained outstanding at September 30, 2018. Our substantial indebtedness may increase our vulnerability to any generally adverse economic and industry conditions.

Our ability to make scheduled payments of the principal and interest when due, or to refinance our borrowings under the term loan facility, will depend on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not continue to generate cash flow from operations in the future sufficient to satisfy our obligations under our indebtedness, and any future indebtedness we may incur and to make necessary capital expenditures. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as reducing or delaying

79

investments or capital expenditures, selling assets, refinancing or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance the term loans or existing or future indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on the loan facility or future indebtedness.

We may still incur substantially more debt or take other actions, which would intensify the risks discussed immediately above.

We and our subsidiaries may, subject to any limitations in the terms of the term loan facility, incur additional debt, secure existing or future debt, recapitalize our debt or take a number of other actions that are not limited by the terms of our term loans that could have the effect of diminishing our ability to make payments under the indebtedness when due. If we incur any additional debt, the related risks that we and our subsidiaries face could intensify.

As part of a business unit divestiture, Exar agreed to indemnify the buyer of the business unit for an amount that could be up to the full purchase price received for breaches of representations and warranties, covenants and other matters under the applicable purchase agreement. If Exar were required to make payments in satisfaction of these indemnification obligations, it could have a material adverse effect on our operating results and financial condition.

Under the terms of the purchase agreement relating to the divested business unit, Exar agreed to indemnify the purchaser of the business unit for breaches of representations and warranties and covenants and for certain other matters. Exar also agreed to place $5.0 million of the total purchase price into an escrow account for a period of 18 months to partially secure its indemnification obligations under the purchase agreement; of this amount, $0.8 million remains in escrow as of September 30, 2018; $1.3 million has been released to the purchaser of iML and $2.9 million has been released to Exar through September 30, 2018. Exar’s indemnification obligations for breaches of representations and warranties survived for 12 months from the closing of the sale transaction, except for breaches of representations and warranties covering intellectual property, which survived for 18 months, and breaches of representations and warranties of certain fundamental representations, which survive until the expiration of the applicable statute of limitations. Exar’s maximum indemnification obligation for breaches of representations and warranties, other than intellectual property and fundamental representations, was $13.6 million, its maximum indemnification obligation for breaches of intellectual property representations was $34.0 million, and its maximum indemnity obligation for breaches of fundamental representations is the full purchase price amount (approximately $136.0 million). The aggregate amount recovered by the purchaser in accordance with the indemnification provisions with respect to matters that are subject to the intellectual property representations, together with the aggregate amount recovered by the purchaser in accordance with the indemnification provisions with respect to matters that are subject to the general representations and warranties (other than fundamental representations), will in no event exceed $34.0 million. The Company believes it does not have a material indemnification obligation as of September 30, 2018; however, if the Company were required to make payments in satisfaction of these indemnification obligations related to breaches of representations and warranties of certain fundamental obligations which have not yet expired, it could have a material adverse effect on the Company's business, financial condition, results of operations, and cash flows.

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

Our business acquisitions are accounted for under the acquisition method of accounting by MaxLinear in accordance with accounting principles generally accepted in the United States. Under the acquisition method of accounting, the assets and liabilities of acquired businesses are 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 acquired businesses' balances and results but are not restated retroactively to reflect the historical financial position or results of operations of acquired businesses 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 net tangible assets and identifiable intangible assets of acquired businesses 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. Our acquisitions have resulted in the creation of goodwill based upon the application of the acquisition method of accounting. To the extent the value of goodwill or other intangible assets become impaired, we may be required to incur material charges relating to such impairment. We conduct our annual goodwill impairment analysis on October 31 each year, or more frequently if we believe indicators of impairment exist. In addition, there can be no guarantee that acquired intangible assets, particularly in-process research and development, will generate revenues or profits that we include in our forecast that is the basis for their fair values as of the acquisition date. Any

80

such impairment charges relating to goodwill or other intangible assets 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 common stock. For example, in the nine months endedSeptember 30, 2018 and in the year ended December 31, 2017, we recognized impairment losses of $2.2 million and $2.0 million, respectively, related principally to acquired Exar assets, in the year ended December 31, 2016, we recognized IPR&D impairment losses of $1.3 million related principally to acquired wireless infrastructure access assets, and in the year ended December 31, 2015, we recognized IPR&D impairment losses of $21.6 million related principally to acquired Entropic assets. As of September 30, 2018, our balance sheet reflected goodwill of $238.3 million and other intangible assets of $261.8 million, including IPR&D intangible assets of $4.4 million, and we could recognize impairment charges in the future.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Organization and Summary of Significant Accounting Policies

Organization and Summary of Significant Accounting Policies

Description of Business

MaxLinear, Inc. was incorporated in Delaware in September 2003. MaxLinear, Inc., together with its wholly owned subsidiaries, collectively referred to as MaxLinear, or the Company, is a provider of radio-frequency, or RF, high-performance analog, and mixed-signal communications system-on-chip solutions for the connected home, wired and wireless infrastructure, and industrial and multi-market applications. MaxLinear's customers include electronics distributors, 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 DOCSIS broadband modems and gateways, wireline connectivity devices for in-home networking applications, RF transceivers and modems for wireless carrier access and backhaul infrastructure, fiber-optic modules for data center, metro, and long-haul transport networks, video set-top boxes and gateways, hybrid analog and digital televisions, direct broadcast satellite outdoor and indoor units, and power management and interface products used in these and a range of other markets. The Company is a fabless integrated circuit design company whose products integrate all or a substantial portion of a broadband communication system.

Basis of Presentation and Principles of Consolidation

The accompanying unaudited consolidated financial statements include the accounts of MaxLinear, Inc. and its wholly owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP, 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 GAAP for complete financial statements. All intercompany transactions and investments have been eliminated in consolidation. In the opinion of management, the Company’s unaudited consolidated interim financial statements contain adjustments, including normal recurring accruals necessary to present fairly the Company’s consolidated financial position, results of operations, comprehensive income (loss) and cash flows.

The consolidated balance sheet as of December 31, 2017 was derived from the Company’s audited consolidated financial statements at that date. The accompanying unaudited consolidated interim financial statements should be read in conjunction with the audited consolidated financial statements and related notes thereto for the year ended December 31, 2017 included in the Company’s Annual Report on Form 10-K filed by the Company with the Securities and Exchange Commission, or the SEC, on February 20, 2018, or the Annual Report. Interim results for the three and nine months ended September 30, 2018 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2018.

Use of Estimates

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

Summary of Significant Accounting Policies

Refer to the Company’s Annual Report for a summary of significant accounting policies. On January 1, 2018, the Company adopted Financial Accounting Standards Board, or FASB, Accounting Standards Codification Topic 606, Revenue from Contracts with Customers, or ASC 606, and accordingly, modified its policy on revenue recognition as stated below. The primary impact of adopting ASC 606 for the Company was to accelerate the timing of the Company’s revenue and related cost recognition on products sold via some of its distributors, which changed from recognition upon the sale to the distributors' end customers, or the sell-through method, to recognition upon the Company's sale to the distributor, or the sell-in method. The Company is now also required to estimate the effects of pricing credits to its distributors from contractual price protection and unit rebate provisions, as well as stock rotation rights and record such estimated credits upon the Company's sale to the distributor.

There have been no other material changes to our significant accounting policies during the nine months endedSeptember 30, 2018.

Revenue Recognition

Substantially all of the Company's revenue is generated from sales of the Company’s integrated circuits to electronics distributors, module makers, OEMs, and ODMs under individual customer purchase orders, some of which have underlying master sales agreements that specify terms governing the product sales. Effective January 1, 2018, the Company adopted ASC 606 and recognizes revenue at the point in time when control of the products is transferred to the customer at the estimated net consideration for which collection is probable, taking into account the customer's rights to price protection, other pricing credits, unit rebates, and rights to return unsold product. Transfer of control occurs either when products are shipped to or received by the distributor or direct customer, based on the terms of the specific agreement with the customer, if the Company has a present right to payment and transfer of legal title and the risks and rewards of ownership to the customer has occurred. For most of the Company's product sales, transfer of control occurs upon shipment to the distributor or direct customer. In assessing whether collection of consideration from a customer is probable, the Company considers the customer's ability and intention to pay that amount of consideration when it is due. Payment of invoices is due as specified in the underlying customer agreement, typically 30 days from the invoice date, which occurs on the date of transfer of control of the products to the customer. Since payment terms are less than a year, the Company has elected the practical expedient and does not assess whether a customer contract has a significant financing component.

A five-step approach is applied in the recognition of revenue under ASC 606: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when the Company satisfies a performance obligation. The Company applied ASC 606 to its customer contracts that were not completed before the January 1, 2018 adoption date. Customer purchase orders plus the underlying master sales agreements are considered to be contracts with the customer for purposes of applying the five-step approach under ASC 606.

Pricing adjustments and estimates of returns under contractual stock rotation rights are treated as variable consideration for purposes of determining the transaction price, and are estimated at the time control transfers using the expected value method based on the Company's analysis of actual price adjustment claims by distributors and historical product return rates, and then reassessed at the end of each reporting period. The Company also considers whether any variable consideration is constrained, since such amounts for which it is probable that a significant reversal will occur when the contingency is subsequently resolved are required to be excluded from revenues. Price adjustments are finalized at the time the products are sold through to the end customer and the distributor or end customer submits a claim to reduce the sale price to a pre-approved net price. Stock rotation allowances are capped at a fixed percentage of the Company's sales to a distributor for a period of time, up to six months, as specified in the individual distributor contract. If the Company's current estimates of such credits and rights are materially inaccurate, it may result in adjustments that affect future revenues and gross profits. Returns under the Company's general assurance warranty of products for a period of one to three years have not been material and warranty-related services are not considered a separate performance obligation under the customer contracts. Most of the Company's customers resell our product as part of their product and thus are tax-exempt; however, to the extent the Company collects and remits taxes on product sales from customers, it has elected to exclude from the measurement of transaction price such taxes.

Each distinct promise to transfer products is considered to be an identified performance obligation for which revenue is recognized upon transfer of control of the products to the customer. Although customers may place orders for products to be delivered on multiple dates that may be in different quarterly reporting periods, all of the orders are scheduled within 1 year from the order date. The Company has opted to not disclose the portion of revenues allocated to partially unsatisfied performance obligations, which represent products to be shipped within 12 months under open customer purchase orders, at the end of the current reporting period as allowed under ASC 606. The Company has also elected to record sales commissions when incurred, pursuant to the practical expedient under ASC 340, as the period over which the sales commission asset that would have been recognized is less than one year.

Customer contract liabilities consist of obligations to deliver rebates to customers in the form of units of products which are included in accrued expenses and other current liabilities in the consolidated balance sheets. Other obligations to customers consist of estimates of price protection rights offered to the Company's end customers, which are included in accrued price protection liability in the consolidated balance sheets, as well as price adjustments expected to be claimed by the distributor upon sell-through of the products to their customers, and amounts expected to be returned by distributors under stock rotation rights, which are included in accrued expenses and other current liabilities in the consolidated balance sheets. The Company also records a right of return asset, consisting of amounts representing the products the Company expects to receive from customers in returns, which is included in inventory in the consolidated balance sheets, and is typically settled within six months of transfer of control to the customer, or the period over which stock rotation rights are based. Upon lapse of the time period for stock rotations, or the contractual end to price protection and rebate programs, which is approximately one to two years, and when the Company believes unclaimed amounts are no longer subject to payment and will not be paid, any remaining asset or liability is derecognized by an offsetting entry to cost of net revenue and net revenue. For additional disclosures regarding contract liabilities and other obligations to customers, see Note 12.

The Company assesses customer accounts receivable and contract assets for impairment in accordance with ASC 310-10-35.

The impacts of adopting ASC 606 as shown above were primarily related to the acceleration of the timing of the Company’s revenue and related cost recognition on products sold via some of its distributors, which changed from sale to the distributors' end customers, or the sell-through method, to recognition upon the Company's sale to the distributor, or the sell-in method.

Revenues from sales through the Company’s distributors accounted for 46% and 41% of net revenue for the three months ended September 30, 2018 and 2017, respectively. Revenues from sales through the Company’s distributors accounted for 41% and 31% of net revenue for the nine months ended September 30, 2018 and 2017, respectively.

Recently Adopted Accounting Pronouncements

In May 2014, the FASB, issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which provides for new accounting guidance related to revenue recognition. This new standard replaced all prior U.S. GAAP guidance on this topic and eliminated 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 became effective for the Company on January 1, 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 applied the guidance prospectively with an adjustment to accumulated deficit for the cumulative effect of adoption. Adoption of the amendments in this guidance accelerated the timing of the Company’s revenue and related cost recognition on products sold via some distributors, which changed from the sell-through method to the sell-in method under this guidance. The Company is also required to estimate the effects of pricing credits to its distributors from contractual price protection and unit rebate provisions, as well as stock rotation rights. The Company has performed an assessment of the impact of adopting this new accounting standard on its consolidated financial position and results of operations. The impact of adoption of this new accounting standard for the year ending December 31, 2018 will vary depending on the level of inventory remaining at December 31, 2018 at distributors for which the Company previously recognized revenue on a sell-through basis, and therefore could have a material impact on the Company's revenues for the year ending December 31, 2018. The impact to accumulated deficit as of January 1, 2018 was not material. As a result of applying the guidance prospectively with an adjustment to accumulated deficit in the Company's consolidated financial statements for the cumulative effect of adoption, revenues that would have been recognized on a sell-through basis for the amount of deferred revenue and profit remaining as of the adoption date will not be recognized in earnings for any period.

In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this update include, among other things, a requirement to (1) measure equity investments (except equity method investments) at fair value with changes in fair value recognized in net income, with an option to measure equity investments that do not have readily determinable fair values at cost minus any impairment plus or minus any changes resulting from observable price changes; previously changes in fair value were recognized in other comprehensive income, and (2) separately present financial assets and liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statement. The amendments in this update were effective for the Company beginning in the first quarter of fiscal year 2018. The adoption of the amendments in this update did not have a material impact on the Company's consolidated financial position and results of operations for the three and nine months ended September 30, 2018.

In March 2016, the FASB issued ASU No. 2016-08, Principal versus Agent Considerations (Reporting Revenue Gross versus Net) to clarify the revenue recognition implementation guidance on principal versus agent considerations. The amendments in this update clarify that when another party is involved in providing goods or services to a customer, an entity that is the principal has obtained control of a good or service before it is transferred to a customer, and provides indicators to assist an entity in determining whether it controls a specified good or service prior to the transfer to the customer. An entity that is the principal recognizes revenue in the gross amount of consideration to which it expects to be entitled in exchange for the specified good or service transferred to the customer, whereas an agent recognizes revenue in the amount of any fee or commission to which it expects to be entitled in exchange for arranging for the specified good or service to be provided by the other party. The amendments in this update were effective for the Company beginning in the first quarter of fiscal year 2018, concurrent with and applied on the same basis as the new revenue recognition standard. The adoption of the amendments in this update did not have a material impact on the Company's consolidated financial position and results of operations for the three and nine months ended September 30, 2018.

In August 2016, the FASB issued ASU No. 2016-15, Classification of Certain Cash Receipts and Cash Payments to eliminate the diversity in practice regarding the presentation and classification of certain cash receipts and cash payments, including, among other things, contingent consideration payments made following a business combination, proceeds from the settlement of insurance claims in the statement of cash flows, and debt prepayment or debt extinguishment costs. Cash payments not made soon after the acquisition date up to the amount of the contingent consideration liability recognized at the acquisition date should be classified as financing activities and any excess payments should be classified as operating activities, whereas cash payments made soon after the acquisition date to settle the contingent consideration should be classified as investing activities and cash payments for debt prepayment or debt extinguishment costs should be classified as financing activities. Cash proceeds received from settlement of insurance claims should be classified on the basis of the nature of the related losses. The amendments in this update should be applied using a retrospective transition method to each period presented, unless impracticable, and if impracticable, would be applied prospectively as of the earliest date practicable. The amendments in this update were effective for the Company beginning in the first quarter of fiscal year 2018. The adoption of the amendments in this update did not have a material impact on the Company's consolidated statements of cash flows for the three and nine months ended September 30, 2018.

In May 2017, the FASB issued ASU No. 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting to provide clarity and reduce both (1) diversity in practice and (2) cost and complexity when applying the guidance in Topic 718, Compensation—Stock Compensation, to a change to the terms or conditions of a share-based payment award. The amendments in this update require the Company to account for the effects of a modification in a stock-based award unless the fair value, vesting conditions and classification of the modified award is the same as those of the original award immediately before the original award is modified. If the modification does not affect any of the inputs to the valuation technique that the entity uses to value the award, the entity is not required to estimate the value immediately before and after the modification. The amendments in this update were effective for the Company for fiscal years beginning with fiscal year 2018, including interim periods within those years, with early adoption permitted in any interim period. The amendments in this update are applied prospectively to an award modified on or after the adoption date. Since the Company has not had any modifications to stock-based awards that do not affect the inputs into the Black Scholes fair value calculation, the adoption of this guidance did not have a material impact on the Company's consolidated financial position and results of operations for the three and nine months ended September 30, 2018.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act, or the Tax Act. The Tax Act makes broad and complex changes to the U.S. tax code. On December 22, 2017, the U.S. Securities and Exchange Commission Staff, or SEC Staff, issued guidance in Staff Accounting Bulletin No. 118, or SAB 118, to address certain fact patterns where the accounting for changes in tax laws or tax rates under ASC Topic 740 is incomplete upon issuance of an entity's financial statements for the reporting period in which the Tax Act is enacted. As permitted in SAB 118, in 2017, the Company took a measurement period approach and reported certain provisional amounts, based on reasonable estimates, for certain tax effects in which the accounting under ASC 740 is incomplete. Such provisional amounts are subject to adjustment during a limited measurement period, not to extend one year beyond the tax law enactment date, until the accounting under ASC 740 is complete. The Company also made required supplemental disclosures in the notes to the 2017 consolidated financial statements to accompany the provisional amounts, including the reasons for the incomplete accounting, the additional information or analysis that is needed, and other information relevant to why the Company was not able to complete the accounting required under ASC 740 in a timely manner. For adjustments to previously reported provisional amounts made in the three and nine months ended September 30, 2018, refer to Note 10. Additional adjustments to such reported provisional amounts could result in a material adverse impact to the Company's consolidated financial position and results of operations in 2018.

In February 2018, the FASB issued ASU No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The amendments in this update allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Act. The amendments in this update are effective for the Company beginning in fiscal 2019, including interim periods. Early adoption is permitted. The amendments should be applied either in the period of adoption or retrospectively to each period or periods in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Act is recognized. The Company elected to early adopt this guidance in the three months ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's consolidated financial position and results of operations for the three and nine months ended September 30, 2018.

In March 2018, the FASB issued ASU No. 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118. The amendments in this update amend the SEC paragraphs included in Topic 740 to be consistent with the guidance in SAB 118, which the Company adopted in the three months ended December 31, 2017, as described above.

In June 2018, the FASB issued ASU No. 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, to expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. As a result, the accounting for share-based payment awards to nonemployees and employees will be substantially aligned by eliminating the need to measure nonemployee share-based awards at fair value on the earlier of performance commitment date or date performance is complete. Both employee and nonemployee share-based awards are now measured at grant-date fair value. The amendments in this update are effective for the Company beginning with fiscal year 2019, including interim periods, with early adoption permitted, but no earlier than the Company's adoption of Topic 606. The Company elected to early adopt the amendments in this update as of July 1, 2018, with the cumulative effect of the change recorded against accumulated deficit as of July 1, 2018. As the Company's nonemployee share-based awards are not significant, such adoption did not have a material impact on the Company's consolidated accumulated deficit as of July 1, 2018.

Recently Issued Accounting Pronouncements

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The amendments in this update require a lessee to recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term for all leases with terms greater than twelve months. For leases less than twelve months, an entity is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognize lease expense for such leases generally on a straight-line basis over the lease term. The Company intends to make this election. Also, in July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements, to provide an additional transition method. An entity can now elect not to present comparative financial information under Topic 842 if it recognizes a cumulative-effect adjustment to retained earnings upon adoption. The Company also intends to make this election. The amendments in these update are effective for the Company for fiscal years beginning with fiscal year 2019, including interim periods within those years, with early adoption permitted. The Company has performed a preliminary assessment of the impact of the adoption of the amendments in these updates on the Company's consolidated financial position and results of operations for the Company's leases, which primarily consist of facility leases. Based on that assessment, the Company has determined that the right-of-use asset and lease liability, which is measured at the present value of future lease payments, are expected to have a material impact on the Company's consolidated financial position. In addition, through the adoption date, the Company will complete its inventory of its leases and finalize its assessment of the impact of the adoption of Topic 842.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, to simplify the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. An entity no longer will determine goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if the reporting unit had been acquired in a business combination. Instead, under the amendments in this update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. The Board also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. The amendments in this update are effective for the Company beginning with fiscal year 2020, including interim periods, with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of the amendments in this update is not expected to have a material impact on the Company's consolidated financial position and results of operations.

In July 2018, the FASB issued ASU No. 2018-09, Codification Improvements, to clarify the Codification and prevent unintended application of the guidance. An amendment to ASC 718-740, Compensation—Stock Compensation—Income Taxes, clarifies that excess tax benefits should be recognized in the period in which the amount of the deduction is determined. The transition and effective date guidance is based on the facts and circumstances of each amendment. The amendment identified above will be effective for the Company beginning with fiscal year 2019. The adoption of the amendments in this update is not expected to have a material impact on the Company's consolidated financial position and results of operations.

In July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842, Leases, to clarify on how to apply certain aspects of the new lease accounting standard. The amendments in this update, among other things, better articulates the requirement for a lessee's reassessment of lease classification as of the effective date of a modification, clarifies that a change to an index or rate for variable lease payments does not constitute a resolution of a contingency that would result in the remeasurement of lease payments, and requires entities that apply Topic 842 retrospectively to each reporting period and do not adopt the practical expedients to write off any prior unamortized initial direct costs that do not meet the definition under Topic 842 to equity. The amendments in this update have the same effective date and transition requirements as the new lease standard summarized above. The Company is currently in the process of evaluating the impact of adoption of Topic 842 on the Company’s consolidated financial position and results of operations as stated above.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework— Changes to the Disclosure Requirements for Fair Value Measurement,to improve the fair value measurement reporting of financial instruments. The amendments in this update require, among other things, added disclosure of the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The amendments in this update eliminate, among other things, disclosure of the reasons for and amounts of transfers between Level 1 and Level 2 for assets and liabilities that are measured at fair value on a recurring basis and an entity's valuation processes for Level 3 fair value measurements. The amendments in this update will be effective for the Company beginning with fiscal year 2020, with early adoption permitted. Retrospective application is required for all amendments in this update except the added disclosures, which should be applied prospectively. The adoption of the amendments in this update is not expected to have a material impact on the Company's consolidated financial position and results of operations.

In August 2018, the FASB issued ASU No. 2018-15, Intangibles- Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract, to provide additional guidance on the accounting for costs of implementing cloud computing arrangements that are service contracts. The amendments in this update require the capitalization of implementation costs during the application development stage of such hosting arrangements and amortization of the expense over the term of the arrangement including any option to extend reasonably certain to be exercised or option to terminate reasonably certain not to be exercised. Capitalized implementation costs and amortization thereof are also required to be classified in the same line item in the statements of financial position, operations and cash flows associated with the hosting service fees. The amendments in this update will be effective for the Company beginning with fiscal year 2020, with early adoption permitted. Entities may select retrospective or prospective application to all implementation costs incurred after the adoption date. The adoption of the amendments in this update is not expected to have a material impact on the Company's consolidated financial position and results of operations.

Earnings Per Share [Abstract]

Net Income (Loss) Per Share

Net Income (Loss) Per Share

Basic earnings per share, or 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 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. In periods in which the Company has a net loss, dilutive common stock equivalents are excluded from the calculation of diluted EPS.

The table below presents the computation of basic and diluted EPS:

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

Diluted	$	(0.20	)	$	(0.14	)	$	(0.39	)	$	0.15

For the three months endedSeptember 30, 2018 and 2017, the Company incurred a net loss and accordingly excluded common stock equivalents for outstanding stock-based awards, which represented all potentially dilutive securities, of 3.8 million and 4.5 million, respectively, from the calculation of diluted net loss per share due to their anti-dilutive nature.

For the nine months endedSeptember 30, 2018, the Company also incurred a net loss and accordingly excluded 3.7 million common stock equivalents for outstanding stock-based awards, which represented all potentially dilutive securities, from the calculation of diluted net loss per share as the impact was anti-dilutive. For the nine months ended September 30, 2017, the Company excluded 1.1 million of common stock equivalents for outstanding stock-based awards from the calculation of diluted net income per share due to their anti-dilutive nature.

Under this Agreement and Plan of Merger, the Company agreed to acquire all of Exar's outstanding common stock for $13.00 per share in cash. MaxLinear also assumed certain of Exar's stock-based awards in the merger. MaxLinear paid aggregate cash consideration of $688.1 million including $12.7 million of cash paid to settle certain stock-based awards that were not assumed by MaxLinear in the merger. The Company funded the transaction with cash from the balance sheet of the combined companies, including $235.8 million of cash from Exar, and the net proceeds of approximately $416.8 million from $425.0 million of new transaction debt (Note 8). The Company also assumed a purchase agreement that includes an indemnification obligation from Exar related to a November 9, 2016 business unit divestiture by Exar (Note 13).

In the nine months ended September 30, 2018, the Company made updates to estimates of certain tax-related assets acquired and liabilities assumed with a corresponding net increase to goodwill of $0.3 million related to this acquisition (Note 5). The Company has completed its purchase price allocation accounting associated with this acquisition.

Goodwill and Intangible Assets

Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and Intangible Assets

Goodwill and Intangible Assets

Goodwill

Goodwill arises from the acquisition method of accounting for business combinations and represents the excess of the purchase price over the fair value of the net assets and other identifiable intangible assets acquired. The fair values of net tangible assets and intangible assets acquired are based upon preliminary valuations and the Company's estimates and assumptions are subject to change within the measurement period (potentially up to one year from the acquisition date). During the nine months endedSeptember 30, 2018, the Company adjusted its allocation of purchase price for the acquisition of Exar related to updates to estimates of certain tax-related assets acquired and liabilities assumed with a corresponding net increase in goodwill of $0.3 million.

The following table presents the changes in the carrying amount of goodwill:

	Carrying Amount
	(in thousands)
Balance as of December 31, 2017	$	237,992
Adjustments	338
Balance as of September 30, 2018	$	238,330

The Company performs an annual goodwill impairment assessment on October 31st each year, using a two-step quantitative assessment. 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.

In addition to its annual review, the Company performs a test of impairment when indicators of impairment are present. During the nine months endedSeptember 30, 2018 and 2017, no indications of impairment of the Company's goodwill balances were identified and, as a result, no goodwill impairment was recognized.

Amortization of finite-lived intangible assets in cost of net revenue in the consolidated statements of operations results primarily from acquired developed technology.

The following table sets forth the activity during the nine months endedSeptember 30, 2018 related to finite-lived intangible assets resulting from amortization and impairment losses:

Amortization	(51,034		)
Impairment losses	(2,198		)
Balance as of September 30, 2018	$	257,413

The Company regularly reviews the carrying amount of its long-lived assets subject to depreciation and amortization, as well as the related useful lives, to determine whether indicators of impairment may exist that warrant adjustments to carrying values or estimated useful lives. An impairment loss is 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 is measured based on the excess of the carrying amount of the asset over the asset’s fair value. Impairment losses related to finite-lived intangible assets for the three and nine months endedSeptember 30, 2018 were $2.2 million and related to developed technology acquired from Exar.

The following table presents future amortization of the Company’s finite-lived intangible assets at September 30, 2018:

	Amount

Indefinite-lived Intangible Assets

As of September 30, 2018 and December 31, 2017, total indefinite-lived intangible assets, which consist of acquired in-process research and development, were $4.4 million.

The Company performs its annual assessment of indefinite-lived intangible assets on October 31 each year or more frequently if events or changes in circumstances indicate that the asset might be impaired utilizing a qualitative test as a precursor to the quantitative test comparing the fair value of the assets with their carrying amount. Based on the qualitative test, if it is more likely than not that indicators of impairment exists, the Company proceeds to perform a quantitative analysis. During the nine months endedSeptember 30, 2018, no indicators of impairment were identified and, as a result, no IPR&D impairment losses were recorded. In the nine months endedSeptember 30, 2017, the Company recognized IPR&D impairment losses of $2.0 million related to a single IPR&D project of Exar, which was abandoned.

The composition of financial instruments is as follows:

	September 30, 2018		December 31, 2017
	(in thousands)
Assets
Interest rate swap	$	2,452	$	734

The fair value of the Company’s financial instrument is the amount that would be received in an asset sale or paid to transfer a liability in an orderly transaction between unaffiliated market participants and is recorded using a hierarchical 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 instrument within Level 2 of the fair value hierarchy on the basis of models utilizing market observable inputs. The interest rate swap has been valued on the basis of valuations provided by third-party pricing services, as derived from standard valuation or pricing models. The pricing services may use market-based observable inputs for the interest rate swap over the term of the swap, including one month LIBOR-based yield curves 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. The Company also considers the risk of nonperformance by assessing the swap counterparty's credit risk in the estimate of fair value of the interest rate swap. As of September 30, 2018 and December 31, 2017, the Company has not made any adjustments to the valuations obtained from its third-party pricing providers. 

The following table presents a summary of the Company’s financial instruments that were measured at fair value on a recurring basis and the related level of the fair value hierarchy:

Financial Instruments Not Recorded at Fair Value on a Recurring Basis

Some of the Company’s financial instruments are not measured at fair value on a recurring basis but are recorded at amounts that approximate fair value due to their liquid or short-term nature. Such financial assets and financial liabilities include: cash and cash equivalents, restricted cash, net receivables, certain other assets, accounts payable, accrued price protection liability, accrued expenses, accrued compensation costs, and other current liabilities.

The Company’s long-term debt is not recorded at fair value on a recurring basis, but is measured at fair value for disclosure purposes (Note 8).

On May 12, 2017, the Company entered into a credit agreement with certain lenders and a collateral agent in connection with the acquisition of Exar (Note 3). The credit agreement provides for an initial secured term B loan facility, or the “Initial Term Loan,” in an aggregate principal amount of $425.0 million. The credit agreement permits the Company to request incremental loans in an aggregate principal amount not to exceed the sum of $160.0 million (subject to adjustments for any voluntary prepayments), plus an unlimited amount that is subject to pro forma compliance with certain secured leverage ratio and total leverage ratio tests. Incremental loans are subject to certain additional conditions, including obtaining additional commitments from the lenders then party to the credit agreement or new lenders.

Loans under the credit agreement bear interest, at the Company’s option, at a rate equal to either (i) a base rate equal to the highest of (x) the federal funds rate, plus 0.50%, (y) the prime rate then in effect and (z) an adjusted LIBOR rate determined on the basis of a one- three- or six-month interest period, plus 1.0% or (ii) an adjusted LIBOR rate, subject to a floor of 0.75%, in each case, plus an applicable margin of 2.50% in the case of LIBOR rate loans and 1.50% in the case of base rate loans. Commencing on September 30, 2017, the Initial Term Loan will amortize in equal quarterly installments equal to 0.25% of the original principal amount of the Initial Term Loan, with the balance payable on the maturity date. The Initial Term Loan has a term of seven years and will mature on May 12, 2024, at which time all outstanding principal and accrued and unpaid interest on the Initial Term Loan must be repaid. The Company is also required to pay fees customary for a credit facility of this size and type.

The Company is required to make mandatory prepayments of the outstanding principal amount of term loans under the credit agreement with the net cash proceeds from the disposition of certain assets and the receipt of insurance proceeds upon certain casualty and condemnation events, in each case, to the extent not reinvested within a specified time period, from excess cash flow beyond stated threshold amounts, and from the incurrence of certain indebtedness. The Company has the right to prepay its term loans under the credit agreement, in whole or in part, at any time without premium or penalty, subject to certain limitations and a 1.0% soft call premium applicable during the first six months of the loan term. The Company exercised its right to prepay and made aggregate prepayments of principal of $148.0 million from origination through September 30, 2018.

The Company’s obligations under the credit agreement are required to be guaranteed by certain of its domestic subsidiaries meeting materiality thresholds set forth in the credit agreement. Such obligations, including the guaranties, are secured by substantially all of the assets of the Company and the subsidiary guarantors pursuant to a security agreement with the collateral agent.

The credit agreement contains customary affirmative and negative covenants, including covenants limiting the ability of the Company and its restricted subsidiaries to, among other things, incur debt, grant liens, undergo certain fundamental changes, make investments, make certain restricted payments, and sell assets, in each case, subject to limitations and exceptions. As of September 30, 2018, the Company was in compliance with such covenants. The credit agreement also contains customary events of default that include, among other things, certain payment defaults, cross defaults to other indebtedness, covenant defaults, change in control defaults, judgment defaults, and bankruptcy and insolvency defaults. If an event of default exists, the lenders may require immediate payment of all obligations under the credit agreement, and may exercise certain other rights and remedies provided for under the credit agreement, the other loan documents and applicable law.

As of September 30, 2018 and December 31, 2017, the weighted average effective interest rate payable on the long-term debt was approximately 4.6% and 4.1%, respectively.

The debt is carried at its principal amount, net of unamortized debt discount and issuance costs, and is not adjusted to fair value each period. The issuance date fair value of the liability component of the debt in the amount of $398.5 million was determined using a discounted cash flow analysis, in which the projected interest and principal payments were discounted back to the issuance date of the term loan at a market interest rate for nonconvertible debt of 4.6%, which represents a Level 3 fair value measurement. The debt discount of $2.1 million and debt issuance costs of $6.0 million are being amortized to interest expense using the effective interest method from the issuance date through the contractual maturity date of the term loan of May 12, 2024.

During the three and nine months endedSeptember 30, 2018, the Company recognized total amortization of debt discount and debt issuance costs of $0.3 million and $0.9 million, respectively, to interest expense. During the three and nine months endedSeptember 30, 2017, the Company recognized total amortization of debt discount and debt issuance costs of $0.3 million and $0.5 million, respectively, to interest expense.

The approximate fair value of the term loan as of September 30, 2018 and December 31, 2017was $265.8 million and $360.0 million, respectively, which was estimated on the basis of inputs that are observable in the market and which is considered a Level 2 measurement method in the fair value hierarchy.

As of September 30, 2018 and December 31, 2017, the remaining principal balance on the term loan was $277.0 million and $355.0 million, respectively. The remaining principal balance is due on May 12, 2024 at the maturity date on the term loan.

Interest Rate Swap

In November 2017, the Company entered into a fixed-for-floating interest rate swap with an amortizing notional amount to swap a substantial portion of variable rate LIBOR interest payments under its term loans for fixed interest payments bearing an interest rate of 1.74685%. The Company's outstanding debt is still subject to a 2.5% fixed applicable margin during the term of the loan. The interest rate swap is designated as a cash flow hedge of a portion of floating rate interest payments on long-term debt and effectively fixes the interest rate on a substantial portion of the Company’s long-term debt at approximately 4.25%. Accordingly, the Company applies cash flow hedge accounting to the interest rate swap and it is recorded at fair value as an asset or liability and the effective portion of changes in the fair value of the interest rate swap, as measured quarterly, are reported in other comprehensive income (loss). As of September 30, 2018 and December 31, 2017, the fair value of the interest rate swap asset was $2.5 million and $0.7 million (Note 6), respectively, and is included in other long-term assets in the consolidated balance sheets. The increase in fair value related to the interest rate swap asset included in other comprehensive income for the nine months endedSeptember 30, 2018 was $1.7 million. The decrease in fair value for the three months endedSeptember 30, 2018 included in other comprehensive income was $0.01 million. The interest rate swap expires in October 2020 and the total $1.7 million of unrealized gain recorded in accumulated other comprehensive income at September 30, 2018 is not expected to be recorded against interest expense over the next twelve months.

The total unrecognized compensation cost related to unvested stock options as of September 30, 2018 was $5.5 million, and the weighted average period over which these equity awards are expected to vest is 2.92 years.

Restricted Stock Units and Restricted Stock Awards

The Company calculates the fair value of restricted stock units based on the fair market value of the Company's common stock on the grant date. Stock based compensation is recognized over the vesting period using the straight-line method.

A summary of the Company’s restricted stock unit and restricted stock award activity is as follows:

	Number of Shares (in thousands)		Weighted-Average Grant-Date Fair Value per Share
Outstanding at December 31, 2017	3,183		$	20.13
Granted	2,362		19.42

Canceled	(488	)	20.71
Outstanding at September 30, 2018	3,715		20.18

Employee Stock Purchase Rights and Stock Options

The Company uses the Black-Scholes valuation model to calculate the grant-date fair value of employee stock purchase rights and stock options. Stock based compensation expense is recognized over the vesting period using the straight-line method.

Employee Stock Purchase Rights

During the nine months endedSeptember 30, 2018, there were 151,840 shares of common stock purchased under the ESPP at a weighted average price of $16.14.

The fair values of employee stock purchase rights were estimated using the Black-Scholes option pricing model at their respective grant date using the following assumptions:

	Nine Months Ended
	September 30, 2018
Weighted-average grant date fair value per share	$	5.37
Risk-free interest rate	2.09		%
Dividend yield	—		%
Expected life (in years)	0.50
Volatility	46.00		%

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 expected term is the duration of the offering period for each grant date. In addition, the estimated volatility incorporates the historical volatility over the expected term based on the Company's daily closing stock prices.

Stock Options

A summary of the Company’s stock options activity is as follows:

	Number of Options (in thousands)		Weighted-Average Exercise Price		Weighted-Average Contractual Term (in years)	Aggregate Intrinsic Value (in thousands)
Outstanding at December 31, 2017	3,069		$	8.95

Vested and expected to vest at September 30, 2018	2,998		$	9.79	2.26	$	30,896
Exercisable at September 30, 2018	2,506		$	8.32	1.52	$	29,502

The fair values of stock options were estimated using the Black-Scholes option pricing model on the grant date using the following assumptions:

	Nine Months Ended
	September 30, 2018
Weighted-average grant date fair value per share	$	8.14
Risk-free interest rate	2.76		%
Dividend yield	—		%
Expected life (in years)	5.51
Volatility	44.30		%

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, the estimated volatility incorporates the historical volatility of the Company.

The intrinsic value of stock options exercised was $0.1 million and $0.9 million in the three months endedSeptember 30, 2018 and 2017, respectively. The intrinsic value of stock options exercised was $4.0 million and $15.2 million in the nine months endedSeptember 30, 2018 and 2017, respectively.

Cash received from exercise of stock options was $0.1 million and $1.1 million during the three months endedSeptember 30, 2018 and 2017, respectively. Cash received from exercise of stock options was $1.3 million and $7.1 million during the nine months endedSeptember 30, 2018 and 2017, respectively.

The tax benefit from stock options exercised was $1.2 million and $0.9 million during the three months endedSeptember 30, 2018 and 2017, respectively. The tax benefit from stock options exercised was $3.7 million and $11.2 million during the nine months endedSeptember 30, 2018 and 2017, respectively.

Employee Incentive Bonus

The Company settles a majority of bonus awards for its employees, including executives, in shares of common stock under the 2010 Equity Incentive Plan. When bonus awards are settled in common stock issued under the 2010 Equity Incentive Plan, the number of shares issuable to plan participants is determined based on the closing price of the Company's common stock as determined in trading on the New York Stock Exchange on a date approved by the Board of Directors. In connection with the Company's bonus programs, in February 2018, the Company issued 0.3 million freely-tradable shares of the Company's common stock in settlement of bonus awards to employees, including executives, for the 2017 performance period. At September 30, 2018, the Company has an accrual of $6.5 million for bonus awards for employees for year-to-date achievement in the 2018 performance period. The Company's compensation committee retains discretion to effect payment in cash, stock, or a combination of cash and stock.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

The provision for income taxes primarily relates to projected federal, state, and foreign income taxes. To determine the quarterly provision for income taxes, the Company uses an estimated annual effective tax rate, which is generally based on expected annual income and statutory tax rates in the various jurisdictions in which the Company operates. In addition, the tax effects of certain significant or unusual items are recognized discretely in the quarter during which they occur and can be a source of variability in the effective tax rates from quarter to quarter.

The Company utilizes the asset and liability method of accounting for income taxes, under which deferred taxes are determined based on temporary differences between the financial statement and tax basis of assets and liabilities using tax rates expected to be in effect during the years in which the temporary differences reverse. The Company records a valuation allowance to reduce its deferred taxes to the amount it believes is more likely than not to be realized. In making such determination, the Company considers all available positive and negative evidence quarterly, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and recent financial performance.  Forming a conclusion that a valuation allowance is not required is difficult when there is negative evidence such as cumulative losses in recent years. Based upon the Company's review of all positive and negative evidence, the Company released the valuation allowance against certain of its federal deferred tax assets during the three months ended June 30, 2017. The Company continues to have a valuation allowance on its state deferred taxes, certain of its federal deferred tax assets, and certain foreign deferred tax assets in jurisdictions where the Company has cumulative losses or otherwise is not expected to utilize certain tax attributes. The Company does not incur expense or benefit in certain tax free jurisdictions in which it operates.

The Company recorded an income tax benefit of $2.1 million in the three months endedSeptember 30, 2018 and an income tax benefit of $6.3 million for the three months endedSeptember 30, 2017. The Company recorded an income tax provision of $7.3 million for the nine months endedSeptember 30, 2018 and an income tax benefit of $33.8 million for the nine months endedSeptember 30, 2017.

The income tax provision in the nine months endedSeptember 30, 2018 primarily relates to the mix of pre-tax income among jurisdictions (including the effects of certain intercompany royalty payments), excess tax benefits related to stock-based compensation, and release of uncertain tax positions under ASC 740-10.

The income tax benefit in the nine months endedSeptember 30, 2017 primarily relates to the release of the federal valuation allowance during the three months ended June 30, 2017.

Income tax positions must meet a more-likely-than-not threshold to be recognized. Income tax positions that previously failed to meet the more-likely-than-not threshold are recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not threshold are derecognized in the first financial reporting period in which that threshold is no longer met. The Company records potential penalties and interest accrued related to unrecognized tax benefits within the consolidated statements of income as income tax expense.

During the nine months endedSeptember 30, 2018, the Company’s unrecognized tax benefits increased by $0.5 million. The Company does not expect its unrecognized tax benefits to change significantly over the next 12 months. Accrued interest and penalties associated with uncertain tax positions as of September 30, 2018 were approximately $0.8 million and $0.2 million, respectively.

The Company is subject to federal and state income tax in the United States and is also subject to income tax in various states and foreign tax jurisdictions. At September 30, 2018, the Company’s tax years for 2013, 2012, and 2009 and forward are subject to examination by federal, state, and foreign tax authorities, respectively. The Company is under a routine compliance review by the Inland Revenue Authority of Singapore for its 2016 and 2017 tax years. In addition, the Company is currently under examination by the California Franchise Tax Board for the 2014 and 2015 tax years. The Company does not expect these examinations or reviews to have a material effect on the Company's consolidated financial position or results of operations.  However, certain of the Company's state tax attribute carryforwards, which currently have a full valuation allowance, could be reduced.

In April 2017, the Company's subsidiary in Singapore began operating under certain tax incentives in Singapore, which are generally effective through March 2022, and are conditional upon meeting certain employment and investment thresholds in Singapore. Under the incentives, qualifying income derived from certain sales of the Company's integrated circuits is taxed at a concessionary rate over the incentive period, and there are reduced Singapore withholding taxes on certain intercompany royalties during the incentive period. Primarily because of the Company's Singapore net operating losses and a full valuation allowance in Singapore, the incentives did not have a material impact on the Company's income tax provision in the nine months ended September 30, 2018.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act, or the Tax Act. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning in 2018, the transition of U.S international taxation from a worldwide tax system to a territorial system, which includes a new federal tax on global intangible low-taxed income (Global Minimum Tax or GMT), and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017. In its 2017 consolidated financial statements, the Company calculated its best estimate of the impact of the Tax Act in its 2017 income tax benefit in accordance with its understanding of the Tax Act and guidance available as of the date of the filing of the Annual Report.

In addition, the SEC Staff issued SAB 118, which provides guidance on accounting for the tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act.

The Company was able to make reasonable estimates of certain effects and, therefore, recorded certain provisional adjustments in the 2017 income tax benefit. Refer to Note 10 to the Company's consolidated financial statements included in the Annual Report for further details. During the nine months ended September 30, 2018, the Company recognized no adjustments to the provisional amounts recorded at December 31, 2017. Additionally, the Company has provided provisional amounts for the legislative provisions that are effective as of January 1, 2018, including, but not limited to, the creation of the base erosion anti-abuse tax (BEAT), a new global minimum tax, GMT, a new limitation on deductible interest expense, and limitations on the use of net operating losses.

At September 30, 2018, the Company's accounting for certain elements of the Tax Act is incomplete. The provisional amounts recorded are subject to revisions as the Company completes its analysis of the Tax Act, collects and prepares necessary data, and interprets any additional guidance issued by the U.S. Treasury Department, Internal Revenue Service, or IRS, FASB, and other standard-setting and regulatory bodies. Adjustments to the provisional amounts may materially impact the Company's consolidated income tax provision (benefit) and effective tax rates in the period(s) in which such adjustments are made. In all cases, the Company will continue to make and refine calculations as additional analysis is completed. The Company's accounting for the tax effects of the Tax Act will be completed during the one-year measurement period.

Under U.S. GAAP, the Company is allowed to make an accounting policy choice with respect to the GMT of either (1) treating taxes due on future U.S. inclusions in taxable income related to GMT as a current-period expense when incurred or (2) as a component of deferred income taxes. The Company will make its accounting policy election for this item when its analysis is complete, during the measurement period. At September 30, 2018, because the Company is still evaluating the GMT provisions and an analysis of future taxable income that is subject to GMT, the Company has included GMT related to current year operations only in the estimated annual effective tax rate and has not provided additional GMT on deferred items.

⁽¹⁾ Due to the adoption of ASC 606 using the modified retrospective method, prior period amounts have not been adjusted to reflect the change to recognize certain distributor sales upon sale to the distributor, or the sell-in method, from recognition upon the Company's sale to the distributors' end customers, or the sell-through method, which required the deferral of revenue and profit on such distributor sales.

Contract Liabilities

As of September 30, 2018, customer contract liabilities consist of estimates of obligations to deliver rebates to customers in the form of units of products and were approximately $0.2 million. Revenue recognized in the three and nine months endedSeptember 30, 2018 that was included in the contract liability balance as of January 1, 2018 was immaterial.

There were no material changes in the contract liabilities balance during the three and nine months endedSeptember 30, 2018.

Obligations to Customers for Price Adjustments and Returns and Assets for Right-of-Returns

As of September 30, 2018, obligations to customers consisting of estimates of price protection rights offered to the Company's end customers totaled $14.4 million and are included in accrued price protection liability in the consolidated balance sheets.

Exar iML Divestiture Indemnification

Under the terms of the purchase agreement relating to the November 9, 2016 divestiture of Integrated Memory Logic Limited, or iML, by Exar, Exar agreed to indemnify the purchaser of the business unit for breaches of representations and warranties and covenants and for certain other matters. Exar also agreed to place $5.0 million of the total purchase price into an escrow account for a period of 18 months to partially secure its indemnification obligations under the purchase agreement; of this amount, $0.8 million remains in escrow as of September 30, 2018; $1.3 million has been released to the purchaser of iML and $2.9 million has been released to Exar through September 30, 2018. Exar’s indemnification obligations for breaches of representations and warranties survived for 12 months from the closing of the sale transaction, except for breaches of representations and warranties covering intellectual property, which survived for 18 months, and breaches of representations and warranties of certain fundamental representations, which survive until the expiration of the applicable statute of limitations. Exar’s maximum indemnification obligation for breaches of representations and warranties, other than intellectual property and fundamental representations, was $13.6 million, its maximum indemnification obligation for breaches of intellectual property representations was $34.0 million, and is maximum indemnity obligation for breaches of fundamental representations is the full purchase price amount (approximately $136.0 million). The aggregate amount recovered by the purchaser in accordance with the indemnification provisions with respect to matters that are subject to the intellectual property representations, together with the aggregate amount recovered by the Buyer in accordance with the indemnification provisions with respect to matters that are subject to the general representations and warranties (other than fundamental representations), will in no event exceed $34.0 million. The Company believes it does not have a material indemnification obligation as of September 30, 2018; however, if the Company were required to make payments in satisfaction of these indemnification obligations related to breaches of representations and warranties of certain fundamental obligations which have not yet expired, it could have a material adverse effect on the Company's business, financial condition, results of operations, and cash flows.

CrestaTech Litigation

On January 21, 2014, CrestaTech Technology Corporation, or CrestaTech, filed a complaint for patent infringement against the Company in the United States District Court of Delaware, or the District Court Litigation. In its complaint, CrestaTech alleged that the Company infringed U.S. Patent Nos. 7,075,585, or the ‘585 Patent and 7,265,792, or the ‘792 Patent. In addition to asking for compensatory damages, CrestaTech alleged willful infringement and sought a permanent injunction. CrestaTech also named Sharp Corporation, Sharp Electronics Corp. and VIZIO, Inc. as defendants based upon their alleged use of the Company's television tuners.

On January 28, 2014, CrestaTech filed a complaint with the U.S. International Trade Commission, or ITC, again naming, among others, MaxLinear, Sharp, Sharp Electronics, and VIZIO, or 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. which are collectively referred to with MaxLinear, Sharp and VIZIO as the Company Respondents. CrestaTech’s ITC complaint alleged 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 MaxLinear's accused products that CrestaTech alleged infringe the same two patents asserted in the Delaware action. Through its ITC complaint, CrestaTech sought an exclusion order preventing entry into the United States of certain of the Company's television tuners and televisions containing such tuners from Sharp, Sharp Electronics, and VIZIO. CrestaTech also sought 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 March 10, 2014, the court stayed the District Court Litigation pending resolution of the ITC Investigation.

On December 15, 2014, the ITC held a trial in the ITC Investigation. On February 27, 2015, the Administrative Law Judge, or the ALJ, issued a written Initial Determination, or 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 Company's television tuners and televisions incorporating those tuners manufactured and sold by certain customers infringe three claims of the ‘585 Patent (claims 10, 12 and 13), 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 ITC subsequently issued its opinion, which terminated its investigation. The opinion affirmed the findings of the ALJ 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 ALJ's finding of infringement with respect to the three claims of the '585 Patent that were not held to be invalid.

On November 30, 2015, CrestaTech filed an appeal of the ITC decision with the United States Court of Appeals for the Federal Circuit, or the Federal Circuit. On March 7, 2016, CrestaTech voluntarily dismissed its appeal, resulting in a final determination of the ITC Investigation in the Company's favor.

In addition, the Company has filed four petitions for inter partes review, or IPR, by the US Patent Office, two for each of the CrestaTech patents asserted against the Company. The Patent Trial and Appeal Board, or the PTAB, did not institute two of these IPRs as being redundant to IPRs filed by another party that were already underway for the same CrestaTech patent.  The remaining two petitions were instituted or instituted-in-part meaning, together with the IPRs filed by third parties, there were currently six IPR proceedings instituted involving the two CrestaTech patents asserted against the Company. 

In October 2015, the PTAB issued final decisions in two of the six pending IPR proceedings (one for each of the two asserted patents), holding that all of the reviewed claims are unpatentable. Included in these decisions was one of the three claims of the ‘585 Patent (claim 10) mentioned above in connection with the ITC’s final decision. CrestaTech appealed the PTAB’s decisions at the Federal Circuit. On November 8, 2016, the Federal Circuit issued an opinion affirming the PTAB’s finding of unpatentability.

In August 2016, the PTAB issued final written decisions in the remaining four pending IPR proceedings (two for each of the asserted patents), holding that many of the reviewed claims - including the two remaining claims of the ‘585 Patent which the ITC held were infringed - are unpatentable. The parties have appealed the two decisions related to the ‘585 Patent; however, no appeals were filed as to the PTAB's rulings for the ‘792 Patent. The Federal Circuit heard oral argument on these appeals on December 4, 2017. On December 7, the Federal Circuit issued a Rule 36 affirmance in one of the '585 appeals, affirming that the two remaining claims that the ITC had ruled were valid and infringed (claims 12 and 13) are unpatentable. On January 25, 2018, the Federal Circuit issued its ruling in the other ‘585 appeal, vacating the PTAB's ruling that certain claims were not unpatentable and remanding to the PTAB for further analysis of whether CrestaTech is estopped from arguing and/or has waived the right to argue whether six dependent claims are patentable.

As a result of these IPR decisions, all 13 claims that CrestaTech asserted against the Company in the ITC Investigation have been found to be unpatentable by the PTAB and the Federal Circuit.

On March 18, 2016, CrestaTech filed a petition for Chapter 7 bankruptcy in the Northern District of California. As a result of this proceeding, all rights in the CrestaTech asserted patents, including the right to control the pending litigation, were assigned to CF Crespe LLC, or CF Crespe. CF Crespe became the named party in the then-pending IPRs, Federal Circuit appeal and District Court Litigation.

In April 2017, the Delaware court continued the stay of the District Court Litigation per the parties’ request, pending resolution of the Federal Circuit appeals in the IPRs. On April 3, 2018, the District Court dismissed the District Court Litigation. While Crespe has subsequently suggested that this dismissal may have been in error, Crespe has taken no action to date to re-instate the case. Indeed, in its bankruptcy proceeding Crespe has stated that it “no longer has any valid patent claims that it is asserting in any of the proceedings purchased through the Sale Agreement,” which includes the District Court Litigation against the Company. In re Cresta Technology Corporation, Case No. 16-50808 (N.D. Cal. Bank. 2016) at Dkt. No. 270.

The Company cannot predict the outcome of the District Court Litigation, or the IPRs. Any adverse determination in the District Court Litigation could have a material adverse effect on the Company's business, financial condition, results of operations and cash flows.

Trango Systems, Inc. Litigation

On or about August 2, 2016, Trango Systems, Inc., or Trango, filed a complaint in the Superior Court of California, County of San Diego, Central Division, against defendants Broadcom Corporation, Inc., or Broadcom, and the Company, collectively, Defendants. Trango is a purchaser that alleges various fraud, breach of contract, and interference with economic relations claims in connection with the discontinuance of a chip line the Company acquired from Broadcom in 2016. Trango seeks unspecified general and special damages, pre-judgment interest, expenses and costs, attorneys’ fees, punitive damages, and unspecified injunctive and equitable relief. On June 23, 2017, the Court sustained the Company's demurrer to each cause of action in the second amended complaint filed on or about December 6, 2016. Trango filed its third amended complaint on or about July 13, 2017. On February 23, 2018, the Court sustained, in part, the Company's demurrer, dismissing with prejudice the cause of action for breach of a written contract, and Trango voluntarily dismissed its cause of action for breach of an implied-in-fact contract. The remaining causes of action have been permitted to proceed. On March 15, 2018, Trango filed its fourth amended complaint. The Company filed its answer on April 17, 2018. Also, on April 17, Broadcom filed a cross-complaint against the Company, alleging causes of action for indemnity, contribution and apportionment, and declaratory relief. Broadcom voluntarily dismissed the cross-complaint on June 8, 2018. The trial date is set for May 10, 2019. The Company intends to vigorously defend against the lawsuit as it proceeds.

The Company cannot predict the outcome of the Trango Systems, Inc. litigation. Any adverse determination in the Trango Systems, Inc. litigation could have a material adverse effect on the Company's business, financial condition, results of operations and cash flows.

Other Matters

In addition, from time to time, the Company is subject to threats of litigation or actual litigation in the ordinary course of business, some of which may be material. Other than the CrestaTech and Trango litigation described above, the Company believes that there are no other currently pending litigation matters that, if determined adversely by the Company, would have a material effect on the Company's business or that would not be covered by the Company's existing liability insurance.

The accompanying unaudited consolidated financial statements include the accounts of MaxLinear, Inc. and its wholly owned subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America, or GAAP, 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 GAAP for complete financial statements. All intercompany transactions and investments have been eliminated in consolidation. In the opinion of management, the Company’s unaudited consolidated interim financial statements contain adjustments, including normal recurring accruals necessary to present fairly the Company’s consolidated financial position, results of operations, comprehensive income (loss) and cash flows.

Use of Estimates

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

Revenue Recognition

Substantially all of the Company's revenue is generated from sales of the Company’s integrated circuits to electronics distributors, module makers, OEMs, and ODMs under individual customer purchase orders, some of which have underlying master sales agreements that specify terms governing the product sales. Effective January 1, 2018, the Company adopted ASC 606 and recognizes revenue at the point in time when control of the products is transferred to the customer at the estimated net consideration for which collection is probable, taking into account the customer's rights to price protection, other pricing credits, unit rebates, and rights to return unsold product. Transfer of control occurs either when products are shipped to or received by the distributor or direct customer, based on the terms of the specific agreement with the customer, if the Company has a present right to payment and transfer of legal title and the risks and rewards of ownership to the customer has occurred. For most of the Company's product sales, transfer of control occurs upon shipment to the distributor or direct customer. In assessing whether collection of consideration from a customer is probable, the Company considers the customer's ability and intention to pay that amount of consideration when it is due. Payment of invoices is due as specified in the underlying customer agreement, typically 30 days from the invoice date, which occurs on the date of transfer of control of the products to the customer. Since payment terms are less than a year, the Company has elected the practical expedient and does not assess whether a customer contract has a significant financing component.

A five-step approach is applied in the recognition of revenue under ASC 606: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when the Company satisfies a performance obligation. The Company applied ASC 606 to its customer contracts that were not completed before the January 1, 2018 adoption date. Customer purchase orders plus the underlying master sales agreements are considered to be contracts with the customer for purposes of applying the five-step approach under ASC 606.

Pricing adjustments and estimates of returns under contractual stock rotation rights are treated as variable consideration for purposes of determining the transaction price, and are estimated at the time control transfers using the expected value method based on the Company's analysis of actual price adjustment claims by distributors and historical product return rates, and then reassessed at the end of each reporting period. The Company also considers whether any variable consideration is constrained, since such amounts for which it is probable that a significant reversal will occur when the contingency is subsequently resolved are required to be excluded from revenues. Price adjustments are finalized at the time the products are sold through to the end customer and the distributor or end customer submits a claim to reduce the sale price to a pre-approved net price. Stock rotation allowances are capped at a fixed percentage of the Company's sales to a distributor for a period of time, up to six months, as specified in the individual distributor contract. If the Company's current estimates of such credits and rights are materially inaccurate, it may result in adjustments that affect future revenues and gross profits. Returns under the Company's general assurance warranty of products for a period of one to three years have not been material and warranty-related services are not considered a separate performance obligation under the customer contracts. Most of the Company's customers resell our product as part of their product and thus are tax-exempt; however, to the extent the Company collects and remits taxes on product sales from customers, it has elected to exclude from the measurement of transaction price such taxes.

Each distinct promise to transfer products is considered to be an identified performance obligation for which revenue is recognized upon transfer of control of the products to the customer. Although customers may place orders for products to be delivered on multiple dates that may be in different quarterly reporting periods, all of the orders are scheduled within 1 year from the order date. The Company has opted to not disclose the portion of revenues allocated to partially unsatisfied performance obligations, which represent products to be shipped within 12 months under open customer purchase orders, at the end of the current reporting period as allowed under ASC 606. The Company has also elected to record sales commissions when incurred, pursuant to the practical expedient under ASC 340, as the period over which the sales commission asset that would have been recognized is less than one year.

Customer contract liabilities consist of obligations to deliver rebates to customers in the form of units of products which are included in accrued expenses and other current liabilities in the consolidated balance sheets. Other obligations to customers consist of estimates of price protection rights offered to the Company's end customers, which are included in accrued price protection liability in the consolidated balance sheets, as well as price adjustments expected to be claimed by the distributor upon sell-through of the products to their customers, and amounts expected to be returned by distributors under stock rotation rights, which are included in accrued expenses and other current liabilities in the consolidated balance sheets. The Company also records a right of return asset, consisting of amounts representing the products the Company expects to receive from customers in returns, which is included in inventory in the consolidated balance sheets, and is typically settled within six months of transfer of control to the customer, or the period over which stock rotation rights are based. Upon lapse of the time period for stock rotations, or the contractual end to price protection and rebate programs, which is approximately one to two years, and when the Company believes unclaimed amounts are no longer subject to payment and will not be paid, any remaining asset or liability is derecognized by an offsetting entry to cost of net revenue and net revenue. For additional disclosures regarding contract liabilities and other obligations to customers, see Note 12.

The Company assesses customer accounts receivable and contract assets for impairment in accordance with ASC 310-10-35.

The impacts of adopting ASC 606 as shown above were primarily related to the acceleration of the timing of the Company’s revenue and related cost recognition on products sold via some of its distributors, which changed from sale to the distributors' end customers, or the sell-through method, to recognition upon the Company's sale to the distributor, or the sell-in method.

Recently Adopted Accounting Pronouncements

In May 2014, the FASB, issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which provides for new accounting guidance related to revenue recognition. This new standard replaced all prior U.S. GAAP guidance on this topic and eliminated 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 became effective for the Company on January 1, 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 applied the guidance prospectively with an adjustment to accumulated deficit for the cumulative effect of adoption. Adoption of the amendments in this guidance accelerated the timing of the Company’s revenue and related cost recognition on products sold via some distributors, which changed from the sell-through method to the sell-in method under this guidance. The Company is also required to estimate the effects of pricing credits to its distributors from contractual price protection and unit rebate provisions, as well as stock rotation rights. The Company has performed an assessment of the impact of adopting this new accounting standard on its consolidated financial position and results of operations. The impact of adoption of this new accounting standard for the year ending December 31, 2018 will vary depending on the level of inventory remaining at December 31, 2018 at distributors for which the Company previously recognized revenue on a sell-through basis, and therefore could have a material impact on the Company's revenues for the year ending December 31, 2018. The impact to accumulated deficit as of January 1, 2018 was not material. As a result of applying the guidance prospectively with an adjustment to accumulated deficit in the Company's consolidated financial statements for the cumulative effect of adoption, revenues that would have been recognized on a sell-through basis for the amount of deferred revenue and profit remaining as of the adoption date will not be recognized in earnings for any period.

In January 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. The amendments in this update include, among other things, a requirement to (1) measure equity investments (except equity method investments) at fair value with changes in fair value recognized in net income, with an option to measure equity investments that do not have readily determinable fair values at cost minus any impairment plus or minus any changes resulting from observable price changes; previously changes in fair value were recognized in other comprehensive income, and (2) separately present financial assets and liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statement. The amendments in this update were effective for the Company beginning in the first quarter of fiscal year 2018. The adoption of the amendments in this update did not have a material impact on the Company's consolidated financial position and results of operations for the three and nine months ended September 30, 2018.

In March 2016, the FASB issued ASU No. 2016-08, Principal versus Agent Considerations (Reporting Revenue Gross versus Net) to clarify the revenue recognition implementation guidance on principal versus agent considerations. The amendments in this update clarify that when another party is involved in providing goods or services to a customer, an entity that is the principal has obtained control of a good or service before it is transferred to a customer, and provides indicators to assist an entity in determining whether it controls a specified good or service prior to the transfer to the customer. An entity that is the principal recognizes revenue in the gross amount of consideration to which it expects to be entitled in exchange for the specified good or service transferred to the customer, whereas an agent recognizes revenue in the amount of any fee or commission to which it expects to be entitled in exchange for arranging for the specified good or service to be provided by the other party. The amendments in this update were effective for the Company beginning in the first quarter of fiscal year 2018, concurrent with and applied on the same basis as the new revenue recognition standard. The adoption of the amendments in this update did not have a material impact on the Company's consolidated financial position and results of operations for the three and nine months ended September 30, 2018.

In August 2016, the FASB issued ASU No. 2016-15, Classification of Certain Cash Receipts and Cash Payments to eliminate the diversity in practice regarding the presentation and classification of certain cash receipts and cash payments, including, among other things, contingent consideration payments made following a business combination, proceeds from the settlement of insurance claims in the statement of cash flows, and debt prepayment or debt extinguishment costs. Cash payments not made soon after the acquisition date up to the amount of the contingent consideration liability recognized at the acquisition date should be classified as financing activities and any excess payments should be classified as operating activities, whereas cash payments made soon after the acquisition date to settle the contingent consideration should be classified as investing activities and cash payments for debt prepayment or debt extinguishment costs should be classified as financing activities. Cash proceeds received from settlement of insurance claims should be classified on the basis of the nature of the related losses. The amendments in this update should be applied using a retrospective transition method to each period presented, unless impracticable, and if impracticable, would be applied prospectively as of the earliest date practicable. The amendments in this update were effective for the Company beginning in the first quarter of fiscal year 2018. The adoption of the amendments in this update did not have a material impact on the Company's consolidated statements of cash flows for the three and nine months ended September 30, 2018.

In May 2017, the FASB issued ASU No. 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting to provide clarity and reduce both (1) diversity in practice and (2) cost and complexity when applying the guidance in Topic 718, Compensation—Stock Compensation, to a change to the terms or conditions of a share-based payment award. The amendments in this update require the Company to account for the effects of a modification in a stock-based award unless the fair value, vesting conditions and classification of the modified award is the same as those of the original award immediately before the original award is modified. If the modification does not affect any of the inputs to the valuation technique that the entity uses to value the award, the entity is not required to estimate the value immediately before and after the modification. The amendments in this update were effective for the Company for fiscal years beginning with fiscal year 2018, including interim periods within those years, with early adoption permitted in any interim period. The amendments in this update are applied prospectively to an award modified on or after the adoption date. Since the Company has not had any modifications to stock-based awards that do not affect the inputs into the Black Scholes fair value calculation, the adoption of this guidance did not have a material impact on the Company's consolidated financial position and results of operations for the three and nine months ended September 30, 2018.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act, or the Tax Act. The Tax Act makes broad and complex changes to the U.S. tax code. On December 22, 2017, the U.S. Securities and Exchange Commission Staff, or SEC Staff, issued guidance in Staff Accounting Bulletin No. 118, or SAB 118, to address certain fact patterns where the accounting for changes in tax laws or tax rates under ASC Topic 740 is incomplete upon issuance of an entity's financial statements for the reporting period in which the Tax Act is enacted. As permitted in SAB 118, in 2017, the Company took a measurement period approach and reported certain provisional amounts, based on reasonable estimates, for certain tax effects in which the accounting under ASC 740 is incomplete. Such provisional amounts are subject to adjustment during a limited measurement period, not to extend one year beyond the tax law enactment date, until the accounting under ASC 740 is complete. The Company also made required supplemental disclosures in the notes to the 2017 consolidated financial statements to accompany the provisional amounts, including the reasons for the incomplete accounting, the additional information or analysis that is needed, and other information relevant to why the Company was not able to complete the accounting required under ASC 740 in a timely manner. For adjustments to previously reported provisional amounts made in the three and nine months ended September 30, 2018, refer to Note 10. Additional adjustments to such reported provisional amounts could result in a material adverse impact to the Company's consolidated financial position and results of operations in 2018.

In February 2018, the FASB issued ASU No. 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The amendments in this update allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Act. The amendments in this update are effective for the Company beginning in fiscal 2019, including interim periods. Early adoption is permitted. The amendments should be applied either in the period of adoption or retrospectively to each period or periods in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Act is recognized. The Company elected to early adopt this guidance in the three months ended March 31, 2018. The adoption of this guidance did not have a material impact on the Company's consolidated financial position and results of operations for the three and nine months ended September 30, 2018.

In March 2018, the FASB issued ASU No. 2018-05, Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118. The amendments in this update amend the SEC paragraphs included in Topic 740 to be consistent with the guidance in SAB 118, which the Company adopted in the three months ended December 31, 2017, as described above.

In June 2018, the FASB issued ASU No. 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, to expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. As a result, the accounting for share-based payment awards to nonemployees and employees will be substantially aligned by eliminating the need to measure nonemployee share-based awards at fair value on the earlier of performance commitment date or date performance is complete. Both employee and nonemployee share-based awards are now measured at grant-date fair value. The amendments in this update are effective for the Company beginning with fiscal year 2019, including interim periods, with early adoption permitted, but no earlier than the Company's adoption of Topic 606. The Company elected to early adopt the amendments in this update as of July 1, 2018, with the cumulative effect of the change recorded against accumulated deficit as of July 1, 2018. As the Company's nonemployee share-based awards are not significant, such adoption did not have a material impact on the Company's consolidated accumulated deficit as of July 1, 2018.

Recently Issued Accounting Pronouncements

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The amendments in this update require a lessee to recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term for all leases with terms greater than twelve months. For leases less than twelve months, an entity is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognize lease expense for such leases generally on a straight-line basis over the lease term. The Company intends to make this election. Also, in July 2018, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements, to provide an additional transition method. An entity can now elect not to present comparative financial information under Topic 842 if it recognizes a cumulative-effect adjustment to retained earnings upon adoption. The Company also intends to make this election. The amendments in these update are effective for the Company for fiscal years beginning with fiscal year 2019, including interim periods within those years, with early adoption permitted. The Company has performed a preliminary assessment of the impact of the adoption of the amendments in these updates on the Company's consolidated financial position and results of operations for the Company's leases, which primarily consist of facility leases. Based on that assessment, the Company has determined that the right-of-use asset and lease liability, which is measured at the present value of future lease payments, are expected to have a material impact on the Company's consolidated financial position. In addition, through the adoption date, the Company will complete its inventory of its leases and finalize its assessment of the impact of the adoption of Topic 842.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, to simplify the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. An entity no longer will determine goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if the reporting unit had been acquired in a business combination. Instead, under the amendments in this update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. The Board also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. The amendments in this update are effective for the Company beginning with fiscal year 2020, including interim periods, with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of the amendments in this update is not expected to have a material impact on the Company's consolidated financial position and results of operations.

In July 2018, the FASB issued ASU No. 2018-09, Codification Improvements, to clarify the Codification and prevent unintended application of the guidance. An amendment to ASC 718-740, Compensation—Stock Compensation—Income Taxes, clarifies that excess tax benefits should be recognized in the period in which the amount of the deduction is determined. The transition and effective date guidance is based on the facts and circumstances of each amendment. The amendment identified above will be effective for the Company beginning with fiscal year 2019. The adoption of the amendments in this update is not expected to have a material impact on the Company's consolidated financial position and results of operations.

In July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842, Leases, to clarify on how to apply certain aspects of the new lease accounting standard. The amendments in this update, among other things, better articulates the requirement for a lessee's reassessment of lease classification as of the effective date of a modification, clarifies that a change to an index or rate for variable lease payments does not constitute a resolution of a contingency that would result in the remeasurement of lease payments, and requires entities that apply Topic 842 retrospectively to each reporting period and do not adopt the practical expedients to write off any prior unamortized initial direct costs that do not meet the definition under Topic 842 to equity. The amendments in this update have the same effective date and transition requirements as the new lease standard summarized above. The Company is currently in the process of evaluating the impact of adoption of Topic 842 on the Company’s consolidated financial position and results of operations as stated above.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework— Changes to the Disclosure Requirements for Fair Value Measurement,to improve the fair value measurement reporting of financial instruments. The amendments in this update require, among other things, added disclosure of the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The amendments in this update eliminate, among other things, disclosure of the reasons for and amounts of transfers between Level 1 and Level 2 for assets and liabilities that are measured at fair value on a recurring basis and an entity's valuation processes for Level 3 fair value measurements. The amendments in this update will be effective for the Company beginning with fiscal year 2020, with early adoption permitted. Retrospective application is required for all amendments in this update except the added disclosures, which should be applied prospectively. The adoption of the amendments in this update is not expected to have a material impact on the Company's consolidated financial position and results of operations.

In August 2018, the FASB issued ASU No. 2018-15, Intangibles- Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract, to provide additional guidance on the accounting for costs of implementing cloud computing arrangements that are service contracts. The amendments in this update require the capitalization of implementation costs during the application development stage of such hosting arrangements and amortization of the expense over the term of the arrangement including any option to extend reasonably certain to be exercised or option to terminate reasonably certain not to be exercised. Capitalized implementation costs and amortization thereof are also required to be classified in the same line item in the statements of financial position, operations and cash flows associated with the hosting service fees. The amendments in this update will be effective for the Company beginning with fiscal year 2020, with early adoption permitted. Entities may select retrospective or prospective application to all implementation costs incurred after the adoption date. The adoption of the amendments in this update is not expected to have a material impact on the Company's consolidated financial position and results of operations
