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

3


RF receivers and RF receiver SoCs have high levels of functional integration and performance, small silicon die size and low power consumption. Moreover, our proprietary CMOS-based radio system architecture provides to our customers the benefits of superior RF system performance, shorter design cycles, significant design flexibility and low system cost across a wide range of broadband communications applications. It is our intention to drive future optical interconnect products to CMOS versus existing Silicon Germanium BiCMOS and Indium Phosphide process technology designs.
We sell our products to original equipment manufacturers, or OEMs, module makers and original design manufacturers, or ODMs. During 2015, we sold our products to more than 179 end customers. For the year ended December 31, 2015, our net revenue was $300.4 million as compared to $133.1 million in the year ended December 31, 2014.
Recent Developments
On April 30, 2015, we completed its acquisition of Entropic Communications, Inc., or Entropic. Pursuant to the terms of the merger agreement dated as of February 3, 2015, by and among the Company, Entropic, and two wholly-owned subsidiaries of the Company, all of the Entropic outstanding shares were converted into the right to receive consideration consisting of cash and shares of our Class A common stock. We paid an aggregate of $111.1 million and issued an aggregate of 20.4 million shares of our Class A common stock to the stockholders of Entropic. In addition, we assumed all outstanding Entropic stock options and unvested restricted stock units that were held by continuing service providers (as defined in the merger agreement). We used Entropic’s cash and cash equivalents to fund a significant portion of the cash portion of the merger consideration and, to a lesser extent, our own cash and cash equivalents.
As a result of the acquisition, we believe we have benefited from the economies of scale across engineering and supply chain operations, as well as from elimination of redundancy across engineering, sales, and general and administrative functions. Entropic had been recognized for pioneering the MoCA® (Multimedia over Coax Alliance) home networking standard and inventing Direct Broadcast Satellite outdoor unit, or DBS ODU, solutions which consist of band translation switch, or BTS, and channel stacking switch, or CSS, products which simplify the installation required to support simultaneous reception of multiple channels from multiple satellites over a single cable. We believe the acquisition of Entropic added significant scale to our analog/mixed-signal business and expanded our addressable market and enhanced the strategic value of the Company’s offerings to broadband and access partners, OEM customers, and service providers. For a discussion of specific risks and uncertainties that could affect our ability to achieve these and other strategic objectives of the acquisition, please refer to Part I, Item 1A, “Risk Factors” under the subsection captioned “Risks Relating to the Proposed Acquisition of Entropic.”
Industry Background
Technological advances in the broadband data, broadcast TV, voice, and wired and wireless data markets are driving dramatic changes in the way consumers access the internet and experience multimedia content. These advances include the ongoing worldwide conversion from analog to digital television broadcasting; the increasing availability of high-speed broadband and wireless data connectivity; the resolution transitions from standard-definition, to high-definition to ultra-high-definition/4K video television; the proliferation of multi-channel digital video recording, or DVR; the proliferation of multimedia content being both accessible and stored in the cloud through cable, satellite and telecommunications carrier services. As a result, system designers are adding enhanced multimedia functionality to set-top boxes and digital televisions, and expanding voice, video and data access functions and capabilities to home broadband gateways and mobile devices, which in turn is creating demand for higher speed optical interconnects in data center, metro, and long-haul transport network applications. We believe that several trends, across multiple target markets, are creating revenue opportunities for providers of RF and analog/mixed-signal solutions. These trends include the following:
Service Provider/Operator: Competing cable, satellite, and other broadband service providers differentiate their services by providing consumers with bundled video, voice, and broadband data access, referred to as triple-play services. These services include advanced features such as; channel guide information, video-on-demand, multi-channel digital video recording, or DVR, and picture-in-picture viewing. Many set-top boxes, including those used for triple-play services, now enable consumers to simultaneously access, and manage multimedia content from multiple locations in the same house. These advanced features require either a home gateway or a set-top box to simultaneously receive, demodulate, and decode multiple signals spread across several channels of frequency bandwidth. Traditional architectures would require that each simultaneously accessed signal require a dedicated RF receiver. In these emerging home gateway or media servers, where content may be delivered using internet protocol or IP, there may be “thin or remote clients” that may not have traditional TV tuners, but necessarily include a broadband RF receiver such as MoCA or WiFi. This greatly increases the number of RF receivers required to be deployed in each set-top box. In addition, in order to deliver increasing data bandwidth to

4


the home, cable MSOs have deployed DOCSIS 3.0 equipment and services, which enable channel bonding, or the concurrent reception of multiple channels, resulting in higher aggregate “sum of the channels” bandwidth available to DOCSIS 3.0 cable subscribers.
Infrastructure and Non-Operator Terrestrial: Growth in data traffic generated from smartphones and tablets, over-the-top, or OTT, streaming video, cloud computing and data analytics in hyper-scale data centers is creating demand for higher speed interconnect products addressing enterprise and telecommunications infrastructure market applications. These solutions provide the interconnect function between the top-of-rack to the core-router within a datacenter, and the metro and long haul connections within a service provider network. Datacenter links are consistently increasing in performance/speed and are currently changing from 1Gbps to 10Gbps on the servers and from 10/40Gbps to 100Gbps on the routers and switches, and we believe that over the next several years they will likely migrate to 400Gbps. In the markets for non-operator terrestrial solutions, consumers are utilizing a broad array of consumer electronic devices beyond the television, such as personal computers, netbooks, tablets, and mobile phones to access broadcast television and other multimedia content. Specifically, with the increased popularity of accessing multimedia content over-the-top, or OTT, via broadband-enabled streaming services, consumers are increasingly augmenting these OTT multimedia content services with local free-to-air broadcast programming. Consumers can access these terrestrial broadcasts through set-top boxes containing terrestrial RF receiver solutions.
As a result of these trends, RF and analog/mixed signal receiver technology is being deployed in a variety of devices for the terrestrial, cable, satellite, datacenter, and metro and long-haul telecom transport network markets. The proliferation of applications with advanced features has led to an increase in the number of devices with multiple RF receivers and RF receiver SoCs. RF receivers incorporate RF, digital and analog signal processing functions.
Challenges Faced by Providers of Systems and RF Receivers and Optical Interconnects
The stringent performance requirements of broadband communications and optical interconnect applications and the distinct technological challenges associated with the terrestrial, cable, satellite, datacenter, and metro and long-haul telecom transport markets present significant obstacles to service providers and system designers. In particular, designing and implementing RF receivers to capture broadcast digital television signals is extremely challenging due in part to the wide frequency band across which broadcast digital television signals are transmitted. As compared to other digital radio technologies, such as those found in cellular, WiFi and Bluetooth applications, television signals that are broadcast over air, on cable, and by satellite are acquired over a much wider frequency band and encounter many more sources of interference. As a result, traditionally, design and implementation of these RF receivers have been accomplished using conventional radio system architectures that employ multiple discrete components and are fabricated using expensive special purpose semiconductor manufacturing processes, such as silicon germanium, gallium arsenide, and special purpose CMOS-based RF process technologies.
The core challenges of capturing and processing high quality broadband communications signals are common to the terrestrial, cable, and satellite markets. These challenges include:
Design Challenges of Receiving Multiple RF Signals. System designers and service providers across various markets seek to enhance consumer appeal through the addition of new features in their products. Incorporating more than one channel of RF reception in an electronic device enables many of these features and advanced applications that are rapidly becoming a part of the standard offering from device makers and service providers. For example, in the cable set-top box market, it is necessary to support the simultaneous reception of multiple channels for voice, video and data applications in many system designs. In order to meet such requirements, OEMs must employ either multiple narrow or wideband RF receivers or Full Spectrum Capture (FSCTM) receiver SoCs in their system design. Each additional RF receiver poses new challenges to the system designer, such as increased design complexity, overall cost, circuit board space, power consumption and heat dissipation. In addition, a high level of integration in multiple-receiver designs is necessary to combat the reliability and signal interference issues arising from the close proximity of sensitive RF elements.
Signal Clarity Performance Requirements. Television reception requires a robust and clear signal to provide an adequate user experience. One of the core attributes of system performance is signal clarity, often measured by the signal-to-noise ratio parameter, which measures the strength of the desired signal relative to the combined noise and undesired signal strength in the same channel. Television reception requires an RF receiver that has a wide dynamic range and the ability to isolate the desired signal from the undesired signals, which include the noise

5


generated by extraneous radio waves and interferers produced by home networking systems such as wireless local area network, or WLAN, and Bluetooth. Traditional RF receiver implementations utilized expensive discrete components, such as band-pass filters, resonance elements and varactor diodes to meet the stringent requirements imposed by broadband television reception. In high speed mobile environments, a method known as diversity combining of radio signals, in which the desired signal is captured using multiple RF receivers and reconstructed into a single signal, has been employed to improve the signal-to-noise ratio. Diversity combining of radio signals requires substantial RF, digital signal processing and software expertise. Both the traditional broadband reception and diversity combining of RF signals in mobile environments are difficult to implement and pose challenges to RF receiver providers.
Multiple Standards. Worldwide, there are several regional standards for the transmission and reception of broadband analog and digital TV signals. Technical performance, feature requirements and the predominance of a particular means of TV transmission vary regionally. Further, each major geographic region has adopted its own TV standard for cable, terrestrial, and satellite transmissions, such as DVB-T/T2/C/C2/S/S2, ATSC, NTSC, ISDB-T, PAL, SECAM, DTMB, CMMB, etc. As a result of these multiple standards, there are region-specific RF receiver requirements and implementations, which make global standards compliance extremely challenging. Many system designers prefer a multiple standards and protocol compliant solution that was previously not possible. Providers of RF receivers face the design challenge of providing this flexibility to the system designer without any increase in power consumption, or any loss of performance quality or competitiveness.
Power Consumption. Power consumption is an important consideration for consumers and a critical design specification for system designers. For example, in battery-operated devices such as netbooks and notebooks, and voice-enabled cable modems, long battery life is a differentiating device attribute. In addition, government sponsored programs, such as Energy Star in the U.S., induce consumers to purchase more energy efficient products. For example, in September 2009, the U.S. Environmental Protection Agency announced that Energy Star compliant televisions would be required to be 40% more energy efficient than their noncompliant counterparts. The addition of one or more RF receivers to a system in order to enable digital TV functionality significantly increases the overall power consumption imposing severe platform level design constraints on multiple channel receiver systems. In fact, in some multiple receiver system designs, a majority of the system’s overall power consumption is attributable to the RF receiver and related components. Providers of RF receivers and RF receiver SoCs are confronted with the design challenge of lowering power consumption while maintaining or improving device performance.
Size. The size of electronic components, such as RF receivers, is a key consideration for system designers and service providers. Given the proliferation of the number of RF receivers in broadband service provider video and data gateways market, size can be a determining factor for whether or not a particular component, such as an RF receiver is designed into the product. In the television market, as system designers create thinner flat-screen displays, the size of RF receivers is becoming a significant consideration, especially when multiple RF receivers are incorporated in a single system.
The challenges of processing high-speed optical interconnect signals for datacenter, metro and long-haul telecommunications transport markets include:
Optical Fiber Channel Impairments. The optical properties of the fiber material results in impairments to the optical signal that is being propagated across the fiber. These impairments include loss of light intensity, modal, chromatic and polarization dispersion as the light propagates through the fiber. These impairments result in degradation of signal integrity which contributes to effective reduction in data throughput.
Optical Device Technology. The state-of-art in optical device technology today lags the speeds contemplated for data traffic within cloud data centers and transport links between telecom data centers. So, there are severe physical limits to the conversion of electrical signals to optical signals and vice versa at extremely high speeds. These limitations arise from bandwidth, nonlinearities, and noise properties in lasers, modulators, and photo detectors.
Form Factor. The form factor of the face plates in server, storage, switch, and networking racks in data centers limits the capacity to dissipate heat generated by electrical and optical devices inside the transceivers to which optical fibers are connected. As data rates increase dramatically, the physical form of the face plates and connectors does not scale to cope with accompanying increase in power density.

Our RF Receiver Solution
We are a provider of integrated, radio-frequency and mixed-signal integrated circuits for broadband communications and data center, metro, and long-haul transport network applications. Our products enable the display of broadband video and data content in a wide range of electronic devices, including cable and terrestrial and satellite set-top boxes, DOCSIS data and voice gateways, hybrid analog and digital televisions, satellite low-noise blocker transponders or outdoor units and optical modules for data center, metro, and long-haul transport network applications.
We combine our high performance analog and mixed-signal semiconductor design skills with our expertise in digital communications systems, software and embedded systems to develop RF receivers and RF receiver SoCs. We integrate our RF receivers with digital demodulation and other communications functions in standard CMOS process technology. Our solutions have the following key features:
Proprietary Radio Architecture. Digital signal processing is at the core of our RF receivers and RF receiver SoCs. Using our proprietary CMOS-based radio architecture, we leverage both analog and digital signal processing to improve system performance across multiple products. The partitioning of the signal processing in the chip between analog and digital domains is designed to deliver high performance, small die size and low power for a given application. Moreover, our architecture is implemented in standard CMOS process technology, which enables us to realize the integration benefits of analog and digital circuits on the same integrated circuit. This allows us to predictably scale the on-chip digital circuits in successive advanced CMOS process technology nodes. Our solutions have been designed into products in markets with extremely stringent specifications for quality, performance and reliability, such as the television and automotive markets. We believe that our success in these markets demonstrates that our solution can be implemented successfully across multiple markets and applications.
High Signal Clarity Performance. We design our RF receivers and RF receiver SoCs to provide high signal clarity performance regardless of the application in which they are employed. For example, in the set-top box market, we deploy our core RF and mixed-signal CMOS process technology platform and radio system architecture to overcome the interference from in-home networks that can degrade cable broadband signals. We believe that signal clarity is more critical in television compared to other communications applications such as voice and data, because signal loss and interference have a more adverse impact on the end user experience.
Highly Integrated. Our products integrate on a single chip the functionality associated with traditional analog and digital integrated circuits and other expensive discrete components. This high level of integration has the cost benefits associated with smaller silicon die area, fewer external components and lower power. Our CMOS-based RF receiver SoC eliminates analog interface circuit blocks and external components situated at the interface between discrete analog and digital demodulator chips and reduces the cost associated with multiple integrated circuit packages and related test costs. We are also able to integrate multiple RF receivers along with a demodulator onto a single die to create application-specific configurations for our customers. Thus, our highly integrated solution reduces the technical difficulties associated with overcoming the undesired interactions between multiple discrete analog and digital integrated circuits comprising a single system. Our solutions reduce the technical burden on system designers in deploying enhanced television functionality in their products.
Low Power. Our products enable our customers to reduce power consumption in consumer electronic devices without compromising the stringent performance requirements of applications such as broadcast television. In addition, our products enable our customers to decrease overall system costs by reducing the power consumption and heat dissipation requirements in their systems. For example, in cable boxes supporting voice applications, low power consumption may enable a reduction in the number of batteries or battery capacity required to support standby and lifeline telephony. In certain set-top boxes, reduced overall power consumption may allow system designers to eliminate one or more cooling fans required to dissipate the heat generated by high power consumption. The benefits of low power consumption increase with the number of RF receivers included in a system.
Scalable Platform. Our product families share a highly modular, core radio system architecture, which enables us to offer RF receiver and RF receiver SoC solutions that meet the requirements of a wide variety of geographies, broadcast standards and applications. This is in contrast to legacy solutions that require significant customization to conform to regional standards, technical performance and feature requirements. Moreover, by leveraging our flexible core architecture platform, our integrated circuit solutions can be deployed across multiple device

7


categories. As a result, our customers can minimize the design resources required to develop applications for multiple target markets. In addition, our engineering resources can be deployed more efficiently to design products for larger addressable markets. We believe that our core technology platform also can be applied to other communications markets with similar performance requirements.
Space Efficient Solution. Our highly integrated CMOS-based RF receivers and RF receiver SoCs have an extremely small silicon die size, require minimal external components and consume very little power. Our unique radio architecture, more specifically our Full-Spectrum Capture™ technology, not only enables us to integrate multiple RF receivers in a chip, but also results in a reduction in the incremental power and die area required per each additional channel of reception. This enables our customers to design multi-receiver applications, such as cable modems and set-top boxes, in an extremely small form factor. In addition, our products are easily adapted to space-constrained devices such as flat screen televisions, netbooks, and laptops.
Our Strategy

Products
Our products are integrated into a wide range of electronic devices, including cable and terrestrial and satellite set-top boxes, DOCSIS data and voice gateways, hybrid analog and digital televisions, satellite low-noise blocker transponders or outdoor units and physical medium devices that go into optical modules for data center, metro, and long-haul transport network applications.
We provide our customers with guidelines, known as reference designs, so that they can efficiently use our products in their product designs. We currently provide the following types of semiconductors:
RF Receivers. These semiconductor products combine RF receiver technology that traditionally required multiple external discrete components, such as very high frequency, or VHF, and ultra-high frequency, or UHF, tracking filters, surface acoustic wave, or SAW, filters, intermediate-frequency, or IF, amplifiers, low noise amplifiers and transformers. All of these external components have been either eliminated or integrated into a single semiconductor produced entirely in standard CMOS process technology.
RF Receiver SoCs. These semiconductor products combine the functionality of RF receivers, and demodulators in a single chip. In some configurations, these products may incorporate multiple RF receivers and single or multiple demodulators in a single chip to provide application or market specific solutions to customers.
Laser Modulator Drivers. These semiconductor products reside in optical modules and provide a constant current source that delivers exactly the current to the laser diode that it needs to operate for a particular application
Transimpedance Amplifiers. These semiconductor products reside in optical modules and provide current-to-voltage conversion, converting the low-level current of a sensor to a voltage.
Clock and Data Recovery Circuits. These semiconductor products generate a clock from an approximate frequency reference, and then phase-aligns to the transitions in the data stream with a phase-locked loop, or PLL.
Customers
We sell our products, directly and indirectly, to original equipment manufacturers, or OEMs, module makers and original design manufacturers, or ODMs, and refer to these as our end customers. By providing a highly integrated reference design solution that our customers can incorporate in their products with minimal modifications, we enable our customers to design cost-effective high performance digital RF receiver and RF receiver SoC solutions rapidly. In the year ended December 31, 2015, we sold our products to more than 179 end customers. A significant but declining portion of our sales to these and other customers are through distributors based in Asia, and we do not consider distributors as our end customers, despite selling the products to and being paid by the distributors.
A significant portion of our net revenue has historically been generated by a limited number of customers. In the years ended December 31, 2015, 2014 and 2013, ten customers accounted for approximately 76%, 67% and 72% of our net revenue, respectively. In the years ended December 31, 2015, 2014 and 2013, Arris Group, Inc., or Arris, represented 28%, 31% and 28% of revenue. Sales to Arris as a percentage of revenue include sales to Motorola Home, which was acquired by Arris in April 2013, for the years ended December 31, 2015, 2014 and 2013. In the year ended December 31, 2015, Cisco Systems, Inc., or Cisco, represented 13% of revenue. In November 2015, Technicolor completed its purchase of Cisco’s connected devices business. The revenue percentage did not include the 1% revenue percentage for Technicolor.
Products shipped to Asia accounted for 91%, 94% and 93% of our net revenue in the years ended December 31, 2015, 2014 and 2013, respectively. Products shipped to Japan accounted for 1%, 7% and 9% of our net revenue in the years ended December 31, 2015, 2014 and 2013, respectively. Products shipped to China and Taiwan accounted for 77% and 8%, respectively, of our net revenue in the year ended December 31, 2015. Products shipped to China and Taiwan accounted for 71% and 6%, respectively, of our net revenue in the year ended December 31, 2014. Products shipped to China and Taiwan accounted for 68% and 8%, respectively, of our net revenue in the year ended December 31, 2013. 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 during the years ended December 31, 2015, 2014 and 2013 related principally to sales to Asian set-top box manufacturers delivering products into Europe, Middle East, and Africa, or EMEA, markets. Similarly, revenue generated from sales of our cable modem products during the years ended December 31, 2015, 2014 and 2013 related principally to sales to Asian ODM’s and contract manufacturers delivering products into European and North American

9


markets. To date, all of our sales have been denominated in United States dollars. See Note 11 to our consolidated financial statements, included in Part IV, Item 15 of this Report for a discussion of total revenue by geographical region for 2015, 2014 and 2013.
Sales and Marketing
We sell our products worldwide through multiple channels, using our direct sales force, third party sales representatives, and a network of domestic and international distributors. We have direct sales personnel covering the United States, Europe and Asia, and operate customer engineering support offices in Carlsbad, Irvine, and San Jose in California; Atlanta in Georgia; Tokyo in Japan; Shanghai and Shenzhen in China; Hsinchu in Taiwan; Seoul in South Korea; and Bangalore, India. We also employ a staff of field applications engineers to provide direct engineering support locally to some of our customers.
Our distributors are independent entities that assist us in identifying and servicing customers in a particular territory, usually on a non-exclusive basis. Sales through distributors accounted for approximately 13%, 28% and 29% of our net revenue in the years ended December 31, 2015, 2014 and 2013, respectively.
Our sales cycles typically require a significant amount of time and a substantial expenditure of resources before we can realize revenue from the sale of products, if any. Our typical sales cycle consists of a multi-month sales and development process involving our customers’ system designers and management. 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 to 24 months for the cable and satellite markets. If successful, this process culminates in a customer’s decision to use our products in its system, which we refer to as a design-win. Volume production may begin within three to nine months after a design-win, depending on the complexity of our customer’s product and other factors upon which we may have little or no influence. Once our products have been incorporated into a customer’s design, they are likely to be used for the life cycle of the customer’s product. Thus, a design-win may result in an extended period of revenue generation. Conversely, a design-loss to our competitors, may adversely impact our financial results for an extended period of time.
We generally receive purchase orders from our customers approximately six to twenty-four weeks prior to the scheduled product delivery date. These purchase orders may be cancelled without charge upon notification, so long as notification is received within an agreed period of time in advance of the delivery date. Because of the scheduling requirements of our foundries and assembly and test contractors, we generally provide our contractors production forecasts and place firm orders for products with our suppliers, up to twenty-four weeks prior to the anticipated delivery date, often without a purchase order from our own customers. Our standard warranty provides that products containing defects in materials, workmanship or product performance may be returned for a refund of the purchase price or for replacement, at our discretion.
Manufacturing
We use third-party foundries and assembly and test contractors to manufacture, assemble and test our semiconductor products. This outsourced manufacturing approach allows us to focus our resources on the design, sale and marketing of our products. Our engineers work closely with our foundries and other contractors to increase yield, lower manufacturing costs and improve product quality.
Wafer Fabrication. We utilize an increasing range of process technologies to manufacture our products, from standard CMOS to more exotic processes including SiGe and GaAs. Within this range of processes, we use a variety of process technology nodes ranging from 0.18µ down to 28 nanometer. We depend on independent silicon foundry manufacturers to support our wafer fabrication requirements. Our key foundry partners include United Microelectronics Corporation or UMC in Taiwan and Singapore, Taiwan Semiconductor Manufacturing Corporation or TSMC in Taiwan, Semiconductor Manufacturing International Corporation or SMIC in China, Global Foundries Inc. in Singapore, Silterra Malaysia Sdn. Bhd. in Malaysia, Tower-Jazz in Newport Beach California, and WIN Semiconductor in Taiwan.
Assembly/packaging and Test. Upon completion of the silicon processing at the foundry, we forward the finished silicon wafers to independent assembly/packaging and test service subcontractors. The majority of our assembly/packaging and test requirements are supported by the following independent subcontractors: Advanced Semiconductor Engineering or ASE in Taiwan (assembly/packaging and test), Giga Solution Technology Co. Ltd. in Taiwan (test only), Amkor Technology in Korea, Philippines, and China (assembly/packaging and test), United Test and Assembly Center or UTAC Holdings Ltd. in Singapore and China (assembly/packaging and test), King Yuan Electronics Co. Ltd. or KYEC in Taiwan (test only), SIGURD Microelectronics Corp. in Taiwan (test only), Siliconware Precision Industries Co. Ltd. or SPIL in Taiwan (assembly/packaging only) and Unisem (M) Berhad in China (assembly/packaging only).

Quality Assurance. We have implemented significant quality assurance procedures to assure high levels of product quality for our customers. We closely monitor the work-in-progress information and production records maintained by our suppliers, and communicate with our third-party contractors to assure high levels of product quality and an efficient manufacturing time cycle. Upon successful completion of the quality assurance procedures, all of our products are stored and shipped to our customers or distributors directly from our third-party contractors in accordance with our shipping instructions.
Research and Development
We believe that our future success depends on our ability to both improve our existing products and to develop new products for both existing and new markets. We direct our research and development efforts largely to the development of new high performance, mixed-signal semiconductor solutions for broadband communications, datacenter, and metro and long-haul telecommunications transport market applications. We target applications that require stringent overall system performance and low power consumption. As new and challenging communication applications proliferate, we believe that many of these applications may benefit from our SoC solutions combining analog and mixed-signal processing with digital signal processing functions. We have assembled a team of highly skilled semiconductor and embedded software design engineers with expertise in broadband RF and mixed-signal integrated circuit design, digital signal processing, communications systems and SoC design. As of December 31, 2015, we had approximately 345 employees in our research and development group. Our engineering design teams are located in Carlsbad, Irvine, Camarillo and San Jose in California; Atlanta in Georgia; Shenzhen in China; and Bangalore in India. Our research and development expense was $85.4 million, $56.6 million and $53.1 million in 2015, 2014 and 2013, respectively.
Competition
We compete with both established and development-stage semiconductor companies that design, manufacture and market analog and mixed-signal broadband RF receiver and optical interconnect products. Our competitors include companies with much longer operating histories, greater name recognition, access to larger customer bases and substantially greater financial, technical and operational resources. In addition, our industry is experiencing substantial consolidation. As a result, our competitors are increasingly large multi-national semi-conductor companies with substantial market influence. Our competitors may develop products that are similar or superior to ours. We consider our primary competitors to be companies with a proven track record of supporting market leaders and the technical capability to develop and bring to market competing broadband RF receiver and RF receiver SoC and optical interconnect products. Our primary competitors include NXP B.V. in cable and terrestrial TV markets, Silicon Laboratories in terrestrial TV markets, RDA Microelectronics and Rafael Microelectronics, Inc. in TV and terrestrial set-top-box markets, Broadcom Corporation in terrestrial, cable, and satellite markets. Competitors we face in our development initiatives targeting datacenter, and metro and long-haul telecommunications transport applications include Inphi, M/A-COM, Semtech, Qorvo, Broadcom, and Microsemi amongst others. In addition, it is quite likely that a number of other public and private companies, including some of our customers and semiconductor platform partners, could be developing competing products for broadband communications, datacenter, and metro and long-haul telecommunications transport applications.
The market for analog and mixed-signal semiconductor products is highly competitive, and we believe that it will grow more competitive as a result of continued technological advances. We believe that the principal competitive factors in our markets include the following:
product performance;
features and functionality;
energy efficiency;
size;
ease of system design;
customer support;
product roadmap;
reputation;
reliability; and

11


price.
We believe that we compete favorably as measured against each of these criteria. However, our ability to compete in the future will depend upon the successful design, development and marketing of compelling RF and mixed-signal semiconductor integrated solutions for high growth communications markets. In addition, our competitive position will depend on our ability to continue to attract and retain talent while protecting our intellectual property.
Intellectual Property Rights
Our success and ability to compete depend, in part, upon our ability to establish and adequately protect our proprietary technology and confidential information. To protect our technology and confidential information, we rely on a combination of intellectual property rights, including patents, trade secrets, copyrights and trademarks. We also protect our proprietary technology and confidential information through the use of internal and external controls, including contractual protections with employees, contractors, business partners, consultants and advisors. Protecting mask works, or the “topography” or semiconductor material designs, of our integrated circuit products is of particular importance to our business and we seek to prevent or limit the ability of others to copy, reproduce or distribute our mask works.
We have 662 issued patents and 327 patent applications pending in the United States. We also have 262 issued foreign patents and 147 other pending foreign patent applications, based on our issued patents and pending patent applications in the United States. Of the total 924 domestic and foreign issued patents, 753 are related to Entropic and 171 are related to Maxlinear. Of the total 474 domestic and foreign pending patents, 204 are related to Entropic and 270 are related to Maxlinear.

We are the owner of twelve trademarks (“MxL,” “MxLWare,” “Full-Spectrum Capture, “FSC,” “Full Spectrum Transceiver,” “Full-Spectrum Transceiver,” “FST,” “C.LINK,” “ENTROPIC,” “ENTROPIC and Design,” ENTROPIC BUILT-IN and Design,” and “ENTROPIC COMMUNICATIONS and Design”) that have been registered and/or published for opposition in the United States.  We also own foreign counterparts (including eight foreign registrations) of certain of these registered trademarks in Argentina, Brazil, Chile, China, the EU, Israel, India, Japan, Korea and Taiwan. We also claim common law rights in certain other trademarks that are not registered.
We may not gain any competitive advantages from our patents and other intellectual property rights. Our existing and future patents may be circumvented, designed around, blocked or challenged as to inventorship, ownership, scope, validity or enforceability. It is possible that we may be provided with information in the future that could negatively affect the scope or enforceability of either our present or future patents. Furthermore, our pending and future patent applications may or may not be granted under the scope of the claims originally submitted in our patent applications. The scope of the claims submitted or granted may or may not be sufficiently broad to protect our proprietary technologies. Moreover, we have adopted a strategy of seeking limited patent protection with respect to the technologies used in or relating to our products.
We are a party to a number of license agreements for various technologies, such as a license agreement with Intel Corporation relating to demodulator technologies that are licensed specifically for use in our products for cable set-top boxes. The agreement was originally entered into with Texas Instruments but was subsequently assigned to Intel Corporation as part of Intel Corporation’s acquisition of Texas Instruments’ cable modem product line in 2010. The license agreement with Intel Corporation has a perpetual term, but Intel Corporation may terminate the agreement for any uncured material breach or in the event of bankruptcy. If the agreement is terminated, we would not be able to manufacture or sell products that contain the demodulator technology licensed from Intel Corporation, and there would be a delay in the shipment of our products containing the technology until we found a replacement for the demodulator technology in the marketplace on commercially reasonable terms or we developed the demodulator technology itself. We believe we could find a substitute for the currently licensed demodulator technology in the marketplace on commercially reasonable terms or develop the demodulator technology ourselves. In either case, obtaining new licenses or replacing existing technology could have a material adverse effect on our business, as described in “Risk Factors—Risks Related to Our Business—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.”
The semiconductor industry is characterized by frequent litigation and other vigorous offensive and protective enforcement actions over rights to intellectual property. Moreover, there are numerous patents in the semiconductor industry, and new patents are being granted rapidly worldwide. Our competitors may obtain patents that block or limit our ability to develop new technology and/or improve our existing products. If our products were found to infringe any patents or other intellectual property rights held by third parties, we could be prevented from selling our products or be subject to litigation fees, statutory fines and/or other significant expenses. We may be required to initiate litigation in order to enforce any patents issued to us, or to determine the scope or validity of a third-party’s patent or other proprietary rights. We may in the future be

12


contacted by third parties suggesting that we seek a license to intellectual property rights that they may believe we are infringing. In addition, in the future, we may be subject to lawsuits by third parties seeking to enforce their own intellectual property rights, as described in “Risk Factors—Risks Related to Our Business—We recently settled and are currently a party to intellectual property litigation and may face additional claims of intellectual property infringement. Current litigation and any future litigation could be time-consuming, costly to defend or settle and result in the loss of significant rights” and in “Item 3—Legal Proceedings.”
Employees
As of December 31, 2015, we had approximately 500 employees, including 345 in research and development, 69 in sales and marketing, 19 in operations and semiconductor technology and 67 in administration. None of our employees is represented by a labor organization or under any collective bargaining arrangement, and we have never had a work stoppage. We consider our employee relations to be good.
Backlog
Our sales are made primarily pursuant to standard purchase orders. Because industry practice allows customers to reschedule, or in some cases, cancel orders on relatively short notice, we do not believe that backlog is a good indicator of our future sales.
Geographic Information
During our last three years, substantially all of our revenue was generated from products shipped to China, Japan and Taiwan, and substantially all of our long-lived assets are located within the United States.
Seasonality
The semiconductor industry is highly cyclical and is characterized by constant and rapid technological change, rapid product obsolescence and price erosion, evolving technical standards, short product life cycles and wide fluctuations in product supply and demand. From time to time, these and other factors, together with changes in general economic conditions, cause significant upturns and downturns in the industry, and in our business in particular.
In addition, our operating results are subject to substantial quarterly and annual fluctuations due to a number of factors, such as the demand for semiconductor solutions for broadband communications applications, the timing of receipt, reduction or cancellation of significant orders, the gain or loss of significant customers, market acceptance of our products and our customers’ products, our ability to timely develop, introduce and market new products and technologies, the availability and cost of products from our suppliers, new product and technology introductions by competitors, intellectual property disputes and the timing and extent of product development costs.

The following discussion provides information concerning the material risks and uncertainties that we have identified and believe may adversely affect our business, our

13


financial condition and our results of operations. Before you decide whether to invest in our securities, you should carefully consider these risks and uncertainties, together with all of the other information included in this Form 10-K and in our other public filings.
On April 30, 2015, we completed our acquisition of Entropic Communications, Inc., or Entropic, and promptly following such acquisition, Entropic merged with and into Excalibur Subsidiary, LLC, with Excalibur Subsidiary, LLC continuing as the surviving entity and changing its name to Entropic Communications, LLC. For the risks relating to our acquisition of Entropic, please refer to the section of these risk factors captioned “Risks Relating to Our Recent Acquisition of Entropic.”
Risks Related to Our Business
We face intense competition and expect competition to increase in the future, which could have an adverse effect on our revenue, revenue growth rate, if any, and market share.
The global semiconductor market in general, and the RF receiver market in particular, are highly competitive. We compete in different target markets to various degrees on the basis of a number of principal competitive factors, including our products’ performance, features and functionality, energy efficiency, size, ease of system design, customer support, product roadmap, reputation, reliability and price, as well as on the basis of our customer support, the quality of our product roadmap and our reputation. We expect competition to increase and intensify as a result of industry consolidation and the resulting creation of larger semiconductor companies. 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 electronic devices, we compete with suppliers of both can tuners and traditional silicon RF receivers, and with providers of physical medium devices for optical interconnect markets. Our competitors range from large, international companies offering a wide range of semiconductor products to smaller companies specializing in narrow markets and internal engineering groups within television, set-top box, data modems and gateway, satellite low-noise blocker, and optical module manufacturers, some of which may be our customers. Our primary competitors include Silicon Labs, NXP B.V., RDA Microelectronics, Inc., Broadcom Ltd (recently created through the merger of Broadcom Corporation and Avago Technologies Limited), and Rafael Microelectronics, Inc. Inphi Corporation, M/A-COM Technology Solutions Holdings, Inc., Semtech Corporation, Qorvo Inc., and Microsemi Corporation (which recently acquired PMC-Sierra) are competitors. It is quite likely that competition in the markets in which we participate will increase in the future as existing competitors improve or expand their product offerings. In addition, it is quite likely that a number of other public and private companies are in the process of developing competing products for digital television and other broadband communication applications. Because our products often are building block semiconductors which provide functions that in some cases can be integrated into more complex integrated circuits, we also face competition from manufacturers of integrated circuits, some of which may be existing customers 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 tuner/demodulator/video processing products, we may lose significant market share to our competitors. Certain of our competitors have fully integrated tuner/demodulator/video processing solutions targeting high performance cable, satellite, or DTV applications, and thereby potentially provide customers with smaller and cheaper solutions. Some of our targeted customers for our optical interconnect solutions are module makers who are vertically integrated, where we compete with internally supplied components.
Our ability to compete successfully depends on 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 consolidation within our industry as some of our competitors have merged with or been acquired by other competitors, and other competitors have begun to collaborate with each other. These developments may materially and adversely affect our current and future target markets and our ability to compete successfully in those markets.
We depend on a limited number of customers, that have undergone or are subject to pending consolidation and who themselves are dependent on a consolidating set of service provider customers, for a substantial portion of our revenue, and the loss of, or a significant reduction in orders from one or more of our major customers could have a material adverse effect on our revenue and operating results.

14


For fiscal 2015, two customers accounted for 41% of our net revenue, and our ten largest customers accounted for 76% of our net revenue. For fiscal 2014, one customer accounted for approximately 31% of our net revenue, and our ten largest customers collectively accounted for approximately 67% of our net revenue. For fiscal 2013, one customer accounted for approximately 28% of our net revenue, and our ten largest customers collectively accounted for approximately 72% of our net revenue. We expect that our operating results for the foreseeable future will continue to depend on sales to a relatively small number of customers and on the ability of these customers to sell products that incorporate our RF receivers or RF receiver SoCs, digital STB video SoCs, DBS ODU, and MoCA® connectivity solutions. In the future, these customers may decide not to purchase our products at all, may purchase fewer products than they did in the past, or may defer or cancel purchases or otherwise alter their purchasing patterns. Factors that could affect our revenue from these large customers include the following:
substantially all of our sales to date have been made on a purchase order basis, which permits our customers to cancel, change or delay product purchase commitments with little or no notice to us and without penalty;
some of our customers have sought or are seeking relationships with current or potential competitors which may affect their purchasing decisions; and
service provider and OEM consolidation across cable, satellite, and fiber markets could result in significant changes to our customers’ technology development and deployment priorities and roadmaps, which could affect our ability to forecast demand accurately and could lead to increased volatility in our business.
In addition, delays in development could impair our relationships with our strategic customers and negatively impact sales of the products under development. Moreover, it is possible that our customers may develop their own product or adopt a competitor’s solution for products that they currently buy from us. If that happens, our sales would decline and our business, financial condition and results of operations could be materially and adversely affected.
Our relationships with some customers may deter other potential customers who compete with these customers from buying our products. To attract new customers or retain existing customers, we may offer these customers favorable prices on our products. In that event, our average selling prices and gross margins would decline. The loss of a key customer, a reduction in sales to any key customer or our inability to attract new significant customers could seriously impact our revenue and materially and adversely affect our results of operations.
A significant portion of our revenue is attributable to demand for our products in markets for broadband and pay-TV operator applications, and consolidation among cable and satellite television operators could adversely affect our future revenues and operating results.
For fiscal 2015, revenue directly attributable to operator applications accounted for approximately 75% of our net revenue. For fiscal 2014, revenue directly attributable to these applications accounted for approximately 76% of our net revenue. For fiscal 2013, revenue directly attributable to cable and satellite operator applications accounted for approximately 77% of our net revenue. Delays in the development of, or unexpected developments in the operator applications markets could have an adverse effect on order activity by manufacturers in these markets and, as a result, on our business, revenue, operating results and financial condition. In addition, consolidation trends among television operators may continue, which could have a material adverse effect on our future operating results and financial condition.
If we fail to penetrate new markets, specifically the market for satellite set-top and gateway boxes and outdoor units, our revenue, revenue growth rate, if any, and financial condition could be materially and adversely affected.
Currently, we sell most of our products to manufacturers of applications for television, to Chinese manufacturers of terrestrial set-top boxes for sale in various markets worldwide, broadband voice and data modems and gateways, and pay-TV set-top boxes and gateways, to manufacturers of satellite outdoor units or LNB’s, and to manufacturers of optical modules for long-haul and metro telecommunications markets. Our future revenue growth, if any, will depend in part on our ability to expand beyond these markets with analog and mixed-signal solutions targeting the markets for high-speed optical interconnects for datacenter, metro, and long-haul optical modules, telecommunications wireless infrastructure, and cable infrastructure products supporting future Cable operator deployments of DOCSIS 3.1. Each of these markets presents distinct and substantial risks. If any of these markets do not develop as we currently anticipate, or if we are unable to penetrate them successfully, it could materially and adversely affect our revenue and revenue growth rate, if any.
We expect broadband data modems/gateways and pay-TV and satellite set-top boxes and video gateways to represent our largest North American and European target market. The North American and European pay-TV set-top box market is

15


dominated by only a few OEMs, including Cisco Systems, Inc. (whose connected devices business was acquired by Technicolor in November 2015), Arris Group, Inc., Pace plc, Humax Co., Ltd., Samsung Electronics Co., Ltd., and Technicolor S.A. These OEMs are large multinational corporations with substantial negotiating power relative to us 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, Time Warner Cable Inc., DIRECTV, and EchoStar Corporation. In addition, our products will need to be compatible with other components in our customers’ designs, including components produced by our competitors or potential competitors. There can be no assurance that these other companies will support or continue to support our products.
If we fail to penetrate these or other new markets upon which we target our resources, our revenue and revenue growth rate, if any, likely will decrease over time and our financial condition could suffer.
We may be unable to make the substantial and productive research and development investments which are required to remain competitive in our business.

The semiconductor industry requires substantial investment in research and development in order to develop and bring to market new and enhanced technologies and products. Many of our products originated with our research and development efforts and we believe have provided us with a significant competitive advantage. For fiscal 2015, our research and development expense was $85.4 million. For fiscal 2014, our research and development expense was $56.6 million. For fiscal 2013, our research and development expense was $53.1 million. For fiscal 2014 and 2015, we continued to increase our research and development expenditures as part of our strategy of devoting focused research and development efforts on the development of innovative and sustainable product platforms. We are committed to investing in new product development internally in order to stay competitive in our markets and plan to maintain research and development and design capabilities for new solutions in advanced semiconductor process nodes such as 40nm and 28nm and beyond. We do not know whether we will have sufficient resources to maintain the level of investment in research and development required to remain competitive as semiconductor process nodes continue to shrink and become increasingly complex. In addition, we cannot assure you that the technologies which are the focus of our research and development expenditures will become commercially successful.
The complexity of our products could result in unforeseen delays or expenses caused by undetected defects or bugs, which could reduce the market acceptance of our new products, damage our reputation with current or prospective customers and adversely affect our operating costs.
Highly complex products like our RF receivers and RF receiver SoCs and physical medium devices for optical modules may contain defects and bugs when they are first introduced or as new versions are released. We have previously experienced, and may in the future experience, defects and bugs and, in particular, have identified liabilities of several million dollars arising from warranty claims related to legacy Entropic products. Where any of our products, including legacy Entropic products, contain defects or bugs, or have reliability, quality or compatibility problems, we may not be able to successfully correct these problems. Consequently, our reputation may be damaged and customers may be reluctant to buy our products, which could materially and adversely affect our ability to retain existing customers and attract new customers, and our financial results. In addition, these defects or bugs could interrupt or delay sales to our customers. If any of these problems are not found until after we have commenced commercial production of a new product (as in the case of the legacy Entropic products experiencing warranty claims), we may be required to incur additional development costs and product recall, repair or replacement costs, and our operating costs could be adversely affected. These problems may also result in warranty or product liability claims against us by our customers or others that may require us to make significant expenditures to defend these claims or pay damage awards. In the event of a warranty claim, we may also incur costs if we compensate the affected customer. We maintain product liability insurance, but this insurance is limited in amount and subject to significant deductibles. There is no guarantee that our insurance will be available or adequate to protect against all claims. We also may incur costs and expenses relating to a recall of one of our customers’ products containing one of our devices. The process of identifying a recalled product in devices that have been widely distributed may be lengthy and require significant resources, and we may incur significant replacement costs, contract damage claims from our customers and reputational harm. Costs or payments made in connection with warranty and product liability claims and product recalls could materially affect our financial condition and results of operations.
Average selling prices of our products could decrease rapidly, which could have a material adverse effect on our revenue and gross margins.
We may experience substantial period-to-period fluctuations in future operating results due to the erosion of our average selling prices. From time to time, we have reduced the average unit price of our products due to competitive pricing pressures,

16


new product introductions by us or our competitors, and for other reasons, and we expect that we will have to do so again in the future. If we are unable to offset any reductions in our average selling prices by increasing our sales volumes or introducing new products with higher margins, our revenue and gross margins will suffer. To support our gross margins, we must develop and introduce new products and product enhancements on a timely basis and continually reduce our and our customers’ costs. Our inability to do so would cause our revenue and gross margins to decline.
If we fail to develop and introduce new or enhanced products on a timely basis, our ability to attract and retain customers could be impaired and our competitive position could be harmed.
We operate in a dynamic environment characterized by rapidly changing technologies and industry standards and technological obsolescence. To compete successfully, we must design, develop, market and sell new or enhanced products that provide increasingly higher levels of performance and reliability and meet the cost expectations of our customers. The introduction of new products by our competitors, the market acceptance of products based on new or alternative technologies, or the emergence of new industry standards could render our existing or future products obsolete. Our failure to anticipate or timely develop new or enhanced products or technologies in response to technological shifts could result in decreased revenue and our competitors winning more competitive bid processes, known as “design wins.” In particular, we may experience difficulties with product design, manufacturing, marketing or certification that could delay or prevent our development, introduction or marketing of new or enhanced products. If we fail to introduce new or enhanced products that meet the needs of our customers or penetrate new markets in a timely fashion, we will lose market share and our operating results will be adversely affected.
In particular, we believe that we will need to develop new products in part to respond to changing dynamics and trends in our end user markets, including (among other trends) consolidation among cable and satellite operators, potential industry shifts away from the hardware devices and other technologies that incorporate our products, and changes in consumer television viewing habits and how consumers access and receive broadcast content and digital broadband services. We cannot predict how these trends will continue to develop or how or to what extent they may affect our future revenues and operating results. We believe that we will need to continue to make substantial investments in research and development in an attempt to ensure a product roadmap that anticipates these types of changes; however, we cannot provide any assurances that we will accurately predict the direction in which our markets will evolve or that we will be able to develop, market, or sell new products that respond to such changes successfully or in a timely manner, if at all.
We recently settled and are currently a party to intellectual property litigation and may face additional claims of intellectual property infringement. Current litigation and any future litigation could be time-consuming, costly to defend or settle and result in the loss of significant rights.
The semiconductor industry is characterized by companies that hold large numbers of patents and other intellectual property rights and that vigorously pursue, protect and enforce intellectual property rights. Third parties have in the past and may in the future assert against us and our customers and distributors their patent and other intellectual property rights to technologies that are important to our business. In particular, from time to time, we receive correspondence from competitors seeking to engage us in discussions concerning potential claims against us, and we receive correspondence from customers seeking indemnification for potential claims related to infringement claims asserted against down-stream users of our products. We investigate these requests as received and could be required to enter license agreements with respect to third party intellectual property rights or indemnify third parties, either of which could have an adverse effect on our future operating results.
On January 21, 2014, CrestaTech Technology Corporation, or CrestaTech, filed a complaint for patent infringement against us in the United States District Court of Delaware (the “District Court Litigation”). In its complaint, CrestaTech alleges that we infringe U.S. Patent Nos. 7,075,585 (the “’585 Patent”) and 7,265,792. In addition to asking for compensatory damages, CrestaTech alleges willful infringement and seeks a permanent injunction. CrestaTech also names Sharp Corporation, Sharp Electronics Corp. and VIZIO, Inc. as defendants based upon their alleged use of our television tuners. On January 28, 2014, CrestaTech filed a complaint with the U.S. International Trade Commission, or ITC, again naming, among others, us, Sharp, Sharp Electronics, and VIZIO (the “ITC Investigation”).
On December 1-5, 2014, the ITC held a trial in the ITC Investigation. On February 27, 2015, the Administrative Law Judge issued a written Initial Determination (“ID”), ruling that the Company Respondents do not violate Section 1337 in connection with CrestaTech’s asserted patents because CrestaTech failed to satisfy the economic prong of the domestic industry requirement pursuant to Section 1337(a)(2). In addition, the ID stated that certain of our television tuners and televisions incorporating those tuners manufactured and sold by certain customers infringe three claims of the ‘585 Patent, and these three

17


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 requested additional briefing from the parties on certain issues under review by the Commission. The ITC subsequently issued its opinion, which terminated its investigation. The opinion affirmed the findings of the administrative law judge that no violation of Section 1337 had occurred because CrestaTech had failed to establish the economic prong of the domestic industry requirement. The ITC also affirmed the administrative law judge's finding of infringement with respect to the three claims of the '585 Patent that were not held to be invalid. On November 30, 2015, CrestaTech filed an appeal of the ITC decision with the United States Court of Appeals for the Federal Circuit (the "Federal Circuit").
In addition, we have filed four petitions for inter partes review ("IPR") by the US Patent Office of the two CrestaTech patents asserted against us. The Patent Trial and Appeal Board (“PTAB”) did not institute two of these IPRs as being redundant to IPRs filed by another party that are already underway for the same CrestaTech patent.  The remaining two petitions were instituted or instituted-in-part and, together with the IPRs filed by third parties, there are currently six IPR proceedings filed involving the two CrestaTech patents asserted against us.  In October 2015, the PTAB issued final decisions in two of the six IPR proceedings, holding that all of the reviewed claims are unpatentable. Included in these decisions was one of the three claims mentioned above. CrestaTech is appealing the PTAB’s decisions at the Federal Circuit.
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 and operating results.
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:

18


any of our present or future patents or patent claims will not lapse or be invalidated, circumvented, challenged or abandoned;
our intellectual property rights will provide competitive advantages to us;
our ability to assert our intellectual property rights against potential competitors or to settle current or future disputes will not be limited by our agreements with third parties;
any of our pending or future patent applications will be issued or have the coverage originally sought;
our intellectual property rights will be enforced in jurisdictions where competition may be intense or where legal protection may be weak;
any of the trademarks, copyrights, trade secrets or other intellectual property rights that we presently employ in our business will not lapse or be invalidated, circumvented, challenged or abandoned; or
we will not lose the ability to assert our intellectual property rights against or to license our technology to others and collect royalties or other payments.
In addition, our competitors or others may design around our protected patents or technologies. Effective intellectual property protection may be unavailable or more limited in one or more relevant jurisdictions relative to those protections available in the United States, or may not be applied for in one or more relevant jurisdictions. If we pursue litigation to assert our intellectual property rights, an adverse decision in any of these legal actions could limit our ability to assert our intellectual property rights, limit the value of our technology or otherwise negatively impact our business, financial condition and results of operations.
Monitoring unauthorized use of our intellectual property is difficult and costly. Unauthorized use of our intellectual property may have occurred or may occur in the future. Although we have taken steps to minimize the risk of this occurring, any such failure to identify unauthorized use and otherwise adequately protect our intellectual property would adversely affect our business. Moreover, if we are required to commence litigation, whether as a plaintiff or defendant as has occurred with CrestaTech, not only will this be time-consuming, but we will also be forced to incur significant costs and divert our attention and efforts of our employees, which could, in turn, result in lower revenue and higher expenses.
We also rely on customary contractual protections with our customers, suppliers, distributors, employees and consultants, and we implement security measures to protect our trade secrets. We cannot assure you that these contractual protections and security measures will not be breached, that we will have adequate remedies for any such breach or that our suppliers, employees or consultants will not assert rights to intellectual property arising out of such contracts.
In addition, we have a number of third-party patent and intellectual property license agreements. Some of these license agreements require us to make one-time payments or ongoing royalty payments. Also, a few of our license agreements contain most-favored nation clauses or other price restriction clauses which may affect the amount we may charge for our products, processes or technology. We cannot guarantee that the third-party patents and technology we license will not be licensed to our competitors or others in the semiconductor industry. In the future, we may need to obtain additional licenses, renew existing license agreements or otherwise replace existing technology. We are unable to predict whether these license agreements can be obtained or renewed or the technology can be replaced on acceptable terms, or at all.
When we settled a trademark dispute with Linear Technology Corporation, we agreed not to register the “MAXLINEAR” mark or any other marks containing the term “LINEAR”. We may continue to use “MAXLINEAR” as a corporate identifier, including to advertise our products and services, but may not use that mark on our products. The agreement does not affect our ability to use our registered trademark “MxL”, which we use on our products. Due to our agreement not to register the “MAXLINEAR” mark, our ability to effectively prevent third parties from using the “MAXLINEAR” mark in connection with similar products or technology may be affected. If we are unable to protect our trademarks, we may experience difficulties in achieving and maintaining brand recognition and customer loyalty.
Our business, revenue and revenue growth, if any, will depend in part on the timing and development of the global transition from analog to digital television, which is subject to numerous regulatory and business risks outside our control.
In the year ended December 31, 2015, sales of our RF receiver products used in digital terrestrial television applications, or DTT, including digital televisions, terrestrial set-top boxes, and terrestrial receivers in satellite video gateways represented a declining, but not insignificant, portion of our revenues. We expect a declining but not insignificant portion of our revenue in

19


future periods to continue to depend on the demand for DTT applications. In contrast to the United States, where the transition from analog to digital television occurred on a national basis in June 2009, in Europe and other parts of the world, the digital transition is being phased in on a local and regional basis and is expected to occur over many years. Many countries in Eastern Europe and Latin America are expected to convert to digital television by the end of 2018, with other countries targeting dates as late as 2024. As a result, our future revenue will depend in part on government mandates requiring conversion from analog to digital television and on the timing and implementation of those mandates. If the ongoing global transition to digital TV standards does not continue to progress or experiences significant delays, our business, revenue, operating results and financial condition would be materially and adversely affected. If during the transition to digital TV standards, consumers disproportionately purchase TV’s with digital or hybrid tuning capabilities, this could diminish the size of the market for our digital-to-analog converter set-top box solutions, and as result our business, revenue, operating results and financial condition would be materially and adversely affected.
Global economic conditions, including factors that adversely affect consumer spending for the products that incorporate our integrated circuits, could adversely affect our revenues, margins, and operating results.
Our products are incorporated in numerous consumer devices, and demand for our products will ultimately be driven by consumer demand for products such as televisions, automobiles, cable modems, and set-top boxes. Many of these purchases are discretionary. Global economic volatility and economic volatility in the specific markets in which the devices that incorporate our products are ultimately sold can cause extreme difficulties for our customers and third-party vendors in accurately forecasting and planning future business activities. This unpredictability could cause our customers to reduce spending on our products, which would delay and lengthen sales cycles. Furthermore, during challenging economic times our customers may face challenges in gaining timely access to sufficient credit, which could impact their ability to make timely payments to us. These events, together with economic volatility that may face the broader economy and, in particular, the semiconductor and communications industries, may adversely affect, our business, particularly to the extent that consumers decrease their discretionary spending for devices deploying our products.
We rely on a limited number of third parties to manufacture, assemble and test our products, and the failure to manage our relationships with our third-party contractors successfully could adversely affect our ability to market and sell our products.
We do not have our own manufacturing facilities. We operate an outsourced manufacturing business model that utilizes third-party foundry and assembly and test capabilities. As a result, we rely on third-party foundry wafer fabrication and assembly and test capacity, including sole sourcing for many components or products. Currently, all of our products are manufactured by United Microelectronics Corporation, or UMC, Silterra Malaysia Sdn Bhd, Global Foundries, Semiconductor Manufacturing International Corporation, or SMIC, Taiwan Semiconductor Manufacturing Corp, or TSMC, Jazz Semiconductor, and WIN Semiconductor at foundries in Taiwan, Singapore, Malaysia, China, and the United States. We also use third-party contractors for all of our assembly and test operations.
Relying on third party manufacturing, assembly and testing presents significant risks to us, including the following:
failure by us, our customers, or their end customers to qualify a selected supplier;
capacity shortages during periods of high demand;
reduced control over delivery schedules and quality;
shortages of materials;
misappropriation of our intellectual property;
limited warranties on wafers or products supplied to us; and
potential increases in prices.
The ability and willingness of our third-party contractors to perform is largely outside our control. If one or more of our contract manufacturers or other outsourcers fails to perform its obligations in a timely manner or at satisfactory quality levels, our ability to bring products to market and our reputation could suffer. For example, in the event that manufacturing capacity is reduced or eliminated at one or more facilities, including as a response to the recent worldwide decline in the semiconductor industry, manufacturing could be disrupted, we could have difficulties fulfilling our customer orders and our net revenue could decline. In addition, if these third parties fail to deliver quality products and components on time and at reasonable prices, we

20


could have difficulties fulfilling our customer orders, our net revenue could decline and our business, financial condition and results of operations would be adversely affected.
Additionally, our manufacturing capacity may be similarly reduced or eliminated at one or more facilities due to the fact that our fabrication and assembly and test contractors are all located in the Pacific Rim region, principally in China, Taiwan, Singapore and Malaysia. The risk of earthquakes in these geographies is significant due to the proximity of major earthquake fault lines, and Taiwan in particular is also subject to typhoons and other Pacific storms. Earthquakes, fire, flooding, or other natural disasters in Taiwan or the Pacific Rim region, or political unrest, war, labor strikes, work stoppages or public health crises, such as outbreaks of H1N1 flu, in countries where our contractors’ facilities are located could result in the disruption of our foundry, assembly or test capacity. Any disruption resulting from these events could cause significant delays in shipments of our products until we are able to shift our manufacturing, assembly or test from the affected contractor to another third-party vendor. There can be no assurance that alternative capacity could be obtained on favorable terms, if at all.
We do not have any long-term supply contracts with our contract manufacturers or suppliers, and any disruption in our supply of products or materials could have a material adverse effect on our business, revenue and operating results.
We currently do not have long-term supply contracts with any of our third-party vendors, including UMC, Silterra Malaysia Sdn Bhd, Global Foundries, SMIC, TSMC, Jazz Semiconductor, and WIN Semiconductor. We make substantially all of our purchases on a purchase order basis, and neither UMC nor our other contract manufacturers are required to supply us products for any specific period or in any specific quantity. Foundry capacity may not be available when we need it or at reasonable prices. Availability of foundry capacity has in the past been reduced from time to time due to strong demand. Foundries can allocate capacity to the production of other companies’ products and reduce deliveries to us on short notice. It is possible that foundry customers that are larger and better financed than we are, or that have long-term agreements with our foundry, may induce our foundry to reallocate capacity to them. This reallocation could impair our ability to secure the supply of components that we need. We expect that it would take approximately nine to twelve months to transition performance of our foundry or assembly services to new providers. Such a transition would likely require a qualification process by our customers or their end customers. We generally place orders for products with some of our suppliers approximately four to five months prior to the anticipated delivery date, with order volumes based on our forecasts of demand from our customers. Accordingly, if we inaccurately forecast demand for our products, we may be unable to obtain adequate and cost-effective foundry or assembly capacity from our third-party contractors to meet our customers’ delivery requirements, or we may accumulate excess inventories. On occasion, we have been unable to adequately respond to unexpected increases in customer purchase orders and therefore were unable to benefit from this incremental demand. None of our third-party contractors has provided any assurance to us that adequate capacity will be available to us within the time required to meet additional demand for our products.
To address capacity considerations, we are in the process of qualifying additional semiconductor fabricators. Qualification will not occur if we identify a defect in a fabricator’s manufacturing process or if our customers choose not to invest the time and expense required to qualify the proposed fabricator. If full qualification of a fabricator does not occur, we may not be able to sell all of the materials produced by this fabricator or to fulfill demand for our products, which would adversely affect our business, revenue and operating results. In addition, the resulting write-off of unusable inventories would have an adverse effect on our operating results.
We may have difficulty accurately predicting our future revenue and appropriately budgeting our expenses particularly as we seek to enter new markets where we may not have prior experience.
Our recent operating history has focused on developing integrated circuits for specific terrestrial, 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 have recently expanded into the market for and physical medium devices for the optical interconnect markets, and are attempting to enter the markets for telecommunications wireless infrastructure and cable infrastructure. Our limited operating experience in new markets or potential markets we may enter, combined with the rapidly evolving nature of our markets in general, substantial uncertainty concerning how these markets may develop and other factors beyond our control, reduces our ability to accurately forecast quarterly or annual revenue. We are currently expanding our staffing and increasing our expense levels in anticipation of future revenue growth. If our revenue does not increase as anticipated, we could incur significant losses due to our higher expense levels if we are not able to decrease our expenses in a timely manner to offset any shortfall in future revenue.

21


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 $97.7 million in 2012, to $119.6 million in 2013, to $133.1 million in 2014 and $300.4 million in 2015. We may not achieve similar growth rates in future periods. You should not rely on our operating results for any prior quarterly or annual periods as an indication of our future operating performance. If we are unable to maintain adequate revenue growth, our financial results could suffer and our stock price could decline.
To manage our growth successfully and handle the responsibilities of being a public company, we believe we must effectively, among other things:
recruit, hire, train and manage additional qualified engineers for our research and development activities, especially in the positions of design engineering, product and test engineering and applications engineering;
add sales personnel and expand customer engineering support offices;
implement and improve our administrative, financial and operational systems, procedures and controls; and
enhance our information technology support for enterprise resource planning and design engineering by adapting and expanding our systems and tool capabilities, and properly training new hires as to their use.
If we are unable to manage our growth effectively, we may not be able to take advantage of market opportunities or develop new products and we may fail to satisfy customer requirements, maintain product quality, execute our business plan or respond to competitive pressures.
If we are unable to attract, train and retain qualified personnel, especially our design and technical personnel, we may not be able to execute our business strategy effectively.
Our future success depends on our ability to retain, attract and motivate qualified personnel, including our management, sales and marketing and finance, and especially our design and technical personnel. We do not know whether we will be able to retain all of these personnel as we continue to pursue our business strategy. Historically, we have encountered difficulties in hiring and retaining qualified engineers because there is a limited pool of engineers with the expertise required in our field. Competition for these personnel is intense in the semiconductor industry. As the source of our technological and product innovations, our design and technical personnel represent a significant asset. The loss of the services of one or more of our key employees, especially our key design and technical personnel, or our inability to retain, attract and motivate qualified design and technical personnel, could have a material adverse effect on our business, financial condition and results of operations.
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. The loss of any member of our senior management team could harm our ability to implement our business strategy and respond to the rapidly changing market conditions in which we operate.
Our customers require our products and our third-party contractors to undergo a lengthy and expensive qualification process which does not assure product sales.
Prior to purchasing our products, our customers require that both our products and our third-party contractors undergo extensive qualification processes, which involve testing of the products in the customer’s system and rigorous reliability testing. This qualification process may continue for six months or more. However, qualification of a product by a customer does not assure any sales of the product to that customer. Even after successful qualification and sales of a product to a customer, a subsequent revision to the RF receiver or RF receiver SoC and physical medium devices for optical modules, changes in our customer’s manufacturing process or our selection of a new supplier may require a new qualification process, which may result in delays and in us holding excess or obsolete inventory. After our products are qualified, it can take six months or more before the customer commences volume production of components or devices that incorporate our products. Despite these uncertainties, we devote substantial resources, including design, engineering, sales, marketing and management efforts, to qualifying our products with customers in anticipation of sales. If we are unsuccessful or delayed in qualifying any of our products with a customer, sales of this product to the customer may be precluded or delayed, which may impede our growth and cause our business to suffer.

22


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

We currently sell a significant but declining portion of our products to customers through our distributors, who maintain their own inventories of our products.
For fiscal 2015, sales through distributors accounted for 13% of our net revenue. For fiscal 2014, sales through distributors accounted for 28% of our net revenue. For fiscal 2013, sales through distributors accounted for 29% of our net revenue. For these distributor transactions, revenue is not recognized until product is shipped to the end customer and the amount that will ultimately be collected is fixed or determinable. Upon shipment of product to these distributors, title to the inventory transfers to the distributor and the distributor is invoiced, generally with 30 day terms. On shipments to our distributors where revenue is not recognized, we record a trade receivable for the selling price as there is a legally enforceable right to payment, relieving the inventory for the carrying value of goods shipped since legal title has passed to the distributor, and record the corresponding gross profit in the consolidated balance sheet as a component of deferred revenue and deferred profit, representing the difference between the receivable recorded and the cost of inventory shipped. Future pricing credits and/or stock rotation rights from our distributors may result in the realization of a different amount of profit included our future consolidated statements of operations than the amount recorded as deferred profit in our consolidated balance sheets.
If our distributors are unable to sell an adequate amount of their inventories of our products in a given quarter to manufacturers and end users or if they decide to decrease their inventories of our products for any reason, our sales through these distributors and our revenue may decline. In addition, if some distributors decide to purchase more of our products than are required to satisfy end customer demand in any particular quarter, inventories at these distributors would grow in that quarter. These distributors likely would reduce future orders until inventory levels realign with end customer demand, which could adversely affect our product revenue in a subsequent quarter.
Our reserve estimates with respect to the products stocked by our distributors are based principally on reports provided to us by our distributors, typically on a weekly basis. To the extent that this resale and channel inventory data is inaccurate or not received in a timely manner, we may not be able to make reserve estimates for future periods accurately or at all.
We are subject to order and shipment uncertainties, and differences between our estimates of customer demand and product mix and our actual results could negatively affect our inventory levels, sales and operating results.
Our revenue is generated on the basis of purchase orders with our customers rather than long-term purchase commitments. In addition, our customers can cancel purchase orders or defer the shipments of our products under certain circumstances. Our products are manufactured using a silicon foundry according to our estimates of customer demand, which requires us to make separate demand forecast assumptions for every customer, each of which may introduce significant variability into our aggregate estimate. We have limited visibility into future customer demand and the product mix that our customers will require, which could adversely affect our revenue forecasts and operating margins. Moreover, because our target markets are relatively new, many of our customers have difficulty accurately forecasting their product requirements and estimating the timing of their new product introductions, which ultimately affects their demand for our products. Historically, because of this limited visibility, actual results have been different from our forecasts of customer demand. Some of these differences have been material, leading to excess inventory or product shortages and revenue and margin forecasts above those we were actually able to achieve. These differences may occur in the future, and the adverse impact of these differences between forecasts and actual results could grow if we are successful in selling more products to some customers. In addition, the rapid pace of innovation in our industry could render significant portions of our inventory obsolete. Excess or obsolete inventory levels could result in unexpected expenses or increases in our reserves that could adversely affect our business, operating results and financial condition. Conversely, if we were to underestimate customer demand or if sufficient manufacturing capacity were unavailable, we could forego revenue opportunities, potentially lose market share and damage our customer relationships. In addition, any significant future cancellations or deferrals of product orders or the return of previously sold products due to manufacturing defects could materially and adversely impact our profit margins, increase our write-offs due to product obsolescence and restrict our ability to fund our operations.
Winning business is subject to lengthy competitive selection processes that require us to incur significant expenditures. Even if we begin a product design, customers may decide to cancel or change their product plans, which could cause us to generate no revenue from a product and adversely affect our results of operations.
We are focused on securing design wins to develop RF receivers and RF receiver SoCs, MoCA SoCs, DBS-ODU SoCs, physical medium devices for optical modules, and SoC solutions targeting infrastructure opportunities within the

23


telecommunications, wireless, and cable 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 36 months for the cable operator market. The delays inherent in these lengthy sales cycles increase the risk that a customer will decide to cancel, curtail, reduce or delay its product plans, causing us to lose anticipated sales. In addition, any delay or cancellation of a customer’s plans could materially and adversely affect our financial results, as we may have incurred significant expense and generated no revenue. Finally, our customers’ failure to successfully market and sell their products could reduce demand for our products and materially and adversely affect our business, financial condition and results of operations. If we were unable to generate revenue after incurring substantial expenses to develop any of our products, our business would suffer.
Our operating results are subject to substantial quarterly and annual fluctuations and may fluctuate significantly due to a number of factors that could adversely affect our business and our stock price.
Our revenue and operating results have fluctuated in the past and are likely to fluctuate in the future. These fluctuations may occur on a quarterly and on an annual basis and are due to a number of factors, many of which are beyond our control. These factors include, among others:
changes in end-user demand for the products manufactured and sold by our customers;
the receipt, reduction or cancellation of significant orders by customers;
fluctuations in the levels of component inventories held by our customers;
the gain or loss of significant customers;
market acceptance of our products and our customers’ products;
our ability to develop, introduce and market new products and technologies on a timely basis;
the timing and extent of product development costs;
new product announcements and introductions by us or our competitors;
incurrence of research and development and related new product expenditures;
seasonality or cyclical fluctuations in our markets;
currency fluctuations;
fluctuations in IC manufacturing yields;
significant warranty claims, including those not covered by our suppliers;
changes in our product mix or customer mix;
intellectual property disputes;
loss of key personnel or the shortage of available skilled workers;
impairment of long-lived assets, including masks and production equipment; and
the effects of competitive pricing pressures, including decreases in average selling prices of our products.

24


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 our 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.
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

25


not within our control. There can be no assurance that these third parties will continue to make their technology, or improvements to the technology, available to us, or that they will continue to support and maintain their technology. Further, due to the limited number of vendors of some types of technology, it may be difficult to obtain new licenses or replace existing technology. Any impairment of the technology or our relationship with these third parties could have a material adverse effect on our business.
Unanticipated changes in our tax rates or unanticipated tax obligations could affect our future results.

Since we operate in different countries and are subject to taxation in different jurisdictions, our future effective tax rates could be impacted by changes in such countries’ tax laws or their interpretations. Both domestic and international tax laws are subject to change as a result of changes in fiscal policy, changes in legislation, evolution of regulation and court rulings. The application of these tax laws and related regulations is subject to legal and factual interpretation, judgment and uncertainty. We cannot determine whether any legislative proposals may be enacted into law or what, if any, changes may be made to such proposals prior to their being enacted into law. If U.S. or international tax laws change in a manner that increases our tax obligation, it could result in a material adverse impact on our net income and our financial position.

The Federal examination by the Internal Revenue Service for the years 2010 and 2011 was completed during the three months ended March 31, 2014. The Company is still subject to examination for 2012 through 2015. In the event we are determined to have any unaccrued tax obligation arising from future audits, our operating results would be adversely affected.

Our future effective tax rate could be unfavorably affected by unanticipated changes in the valuation of our deferred tax assets and liabilities. Changes in our effective tax rate could have a material adverse impact on our results of operations. We record a valuation allowance to reduce our net deferred tax assets to the amount that we believe is more likely than not to be realized. In assessing the need for a valuation allowance, we consider historical levels of income, expectations and risks associated with estimates of future taxable income and ongoing prudent and practical tax planning strategies. On a periodic basis we evaluate our deferred tax asset balance for realizability. To the extent we believe it is more likely than not that some portion of our deferred tax assets will not be realized, we will recognize a valuation allowance against the deferred tax asset. Realization of our deferred tax assets is dependent primarily upon future U.S. taxable income. During the year ended December 31, 2015, we maintained a full valuation allowance on our net federal and state deferred tax assets net of deferred tax liabilities related to indefinite-lived intangibles for which no future realization can be expected.
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 91% of our net revenue in the year ended December 31, 2015. In addition, approximately 33% of our employees are located outside of the United States. All of our products are manufactured, assembled and tested in Asia, and all of our major distributors are located in Asia. Multiple factors relating to our international operations and to particular countries in which we operate could have a material adverse effect on our business, financial condition and results of operations. These factors include:
changes in political, regulatory, legal or economic conditions;
restrictive governmental actions, such as restrictions on the transfer or repatriation of funds and foreign investments and trade protection measures, including export duties and quotas and customs duties and tariffs;
disruptions of capital and trading markets;
changes in import or export licensing requirements;
transportation delays;
civil disturbances or political instability;
geopolitical turmoil, including terrorism, war or political or military coups;
public health emergencies;
differing employment practices and labor standards;
limitations on our ability under local laws to protect our intellectual property;

26


local business and cultural factors that differ from our customary standards and practices;
nationalization and expropriation;
changes in tax laws;
currency fluctuations relating to our international operating activities; and
difficulty in obtaining distribution and support.
In addition to a significant portion of our wafer supply coming from Singapore, China and Malaysia, substantially all of our products undergo packaging and final testing in Taiwan. Any conflict or uncertainty in this country, including due to natural disaster or public health or safety concerns, could have a material adverse effect on our business, financial condition and results of operations. In addition, if the government of any country in which our products are manufactured or sold sets technical standards for products manufactured in or imported into their country that are not widely shared, it may lead some of our customers to suspend imports of their products into that country, require manufacturers in that country to manufacture products with different technical standards and disrupt cross-border manufacturing relationships which, in each case, could have a material adverse effect on our business, financial condition and results of operations. We also are subject to risks associated with international political conflicts involving the U.S. government. For example, in 2008 we were instructed by the U.S. Department of Homeland Security to cease using Polar Star International Company Limited, a distributor based in Hong Kong, that delivered third-party products, to a political group that the U.S. government did not believe should have been provided with the products in question. As a result, we immediately ceased all business operations with that distributor. The loss of Polar Star as a distributor did not materially delay shipment of our products because Polar Star was a non-exclusive distributor and we had in place alternative distribution arrangements. However, we cannot provide assurances that similar disruptions of distribution arrangements in the future will not result in delayed shipments until we are able to identify alternative distribution channels, which could include a requirement to increase our direct sales efforts. Loss of a key distributor under similar circumstances could have an adverse effect on our business, revenues and operating results.
If we suffer losses to our facilities or distribution system due to catastrophe, our operations could be seriously harmed.
Our facilities and distribution system, and those of our third-party contractors, are subject to risk of catastrophic loss due to fire, flood or other natural or man-made disasters. A number of our facilities and those of our contract manufacturers are located in areas with above average seismic activity. The foundries that manufacture all of our wafers are located in Taiwan, Singapore, Malaysia, Southern California and China, and all of the third-party contractors who assemble and test our products also are located in Asia. In addition, our headquarters are located in Southern California. The risk of an earthquake in the Pacific Rim region or Southern California is significant due to the proximity of major earthquake fault lines. For example, in 2002 and 2003, major earthquakes occurred in Taiwan. Any catastrophic loss to any of these facilities would likely disrupt our operations, delay production, shipments and revenue and result in significant expenses to repair or replace the facility.
Our business is subject to various governmental regulations, and compliance with these regulations may cause us to incur significant expenses. If we fail to maintain compliance with applicable regulations, we may be forced to recall products and cease their manufacture and distribution, and we could be subject to civil or criminal penalties.
Our business is subject to various international and U.S. laws and other legal requirements, including packaging, product content, labor, import/export control regulations, and the Foreign Corrupt Practices Act. These regulations are complex, change frequently and have generally become more stringent over time. We may be required to incur significant costs to comply with these regulations or to remedy violations. Any failure by us to comply with applicable government regulations could result in cessation of our operations or portions of our operations, product recalls or impositions of fines and restrictions on our ability to conduct our operations. In addition, because many of our products are regulated or sold into regulated industries, we must comply with additional regulations in marketing our products.
Our products and operations are also subject to the rules of industrial standards bodies, like the International Standards Organization, as well as regulation by other agencies, such as the U.S. Federal Communications Commission. If we fail to adequately address any of these rules or regulations, our business could be harmed.
For example, the SEC adopted a final rule to implement Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act, which requires new disclosures concerning the use of conflict minerals, generally tantalum, tin, gold, or tungsten that originated in the Democratic Republic of the Congo or an adjoining country. These disclosures are required whether or not these products containing conflict minerals are manufactured by us or third parties. Verifying the source of any

27


conflict minerals in our products has created and will continue to create additional costs in order to comply with the new disclosure requirements and we may not be able to certify that the metals in our products are conflict free, which may create issues with our customers. In addition, the new rule may affect the pricing, sourcing and availability of minerals used in the manufacture of our products.
We must conform the manufacture and distribution of our semiconductors to various laws and adapt to regulatory requirements in all countries as these requirements change. If we fail to comply with these requirements in the manufacture or distribution of our products, we could be required to pay civil penalties, face criminal prosecution and, in some cases, be prohibited from distributing our products in commerce until the products or component substances are brought into compliance.
In addition to our acquisitions of Entropic and Physpeed, we may, from time to time, make additional business acquisitions or investments, which involve significant risks.
In addition to the acquisitions of Entropic, which we completed in the second quarter of fiscal 2015, and Physpeed, which we completed in the fourth quarter of fiscal 2014, we may, from time to time, make acquisitions, enter into alliances or make investments in other businesses to complement our existing product offerings, augment our market coverage or enhance our technological capabilities. However, any such transactions could result in:
issuances of equity securities dilutive to our existing stockholders;
substantial cash payments;
the incurrence of substantial debt and assumption of unknown liabilities;
large one-time write-offs;
amortization expenses related to intangible assets;
a limitation on our ability to use our net operating loss carryforwards;
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
the potential loss of key employees, customers and suppliers of the acquired business.
Additionally, in periods subsequent to an acquisition, we must evaluate goodwill and acquisition-related intangible assets for impairment. If such assets are found to be impaired, they will be written down to estimated fair value, with a charge against earnings.
Integrating acquired organizations and their products and services, including the integration of Entropic and Physpeed following completion of the acquisitions, may be expensive, time-consuming and a strain on our resources and our relationships with employees, customers and suppliers, and ultimately may not be successful. The benefits or synergies we may expect from the acquisition of complementary or supplementary businesses may not be realized to the extent or in the time frame we initially anticipate. Some of the risks that may affect our ability to successfully integrate acquired companies, including Entropic and Physpeed, include those associated with:
failure to successfully further develop the acquired products or technology;
conforming the acquired company’s standards, policies, processes, procedures and controls with our operations;
coordinating new product and process development, especially with respect to highly complex technologies;
loss of key employees or customers of the acquired company;
hiring additional management and other critical personnel;
in the case of foreign acquisitions, the need to integrate operations across different cultures and languages and to address the particular economic, currency, political and regulatory risks associated with specific countries;

28


increasing the scope, geographic diversity and complexity of our operations;
consolidation of facilities, integration of the acquired company’s accounting, human resource and other administrative functions and coordination of product, engineering and sales and marketing functions;
the geographic distance between the companies;
liability for activities of the acquired company before the acquisition, including patent and trademark infringement claims, violations of laws, commercial disputes, tax liabilities and other known and unknown liabilities; and
litigation or other claims in connection with the acquired company, including claims for terminated employees, customers, former stockholders or other third parties.
We may be subject to information technology failures, including data protection breaches and cyber-attacks, that could disrupt our operations, damage our reputation and adversely affect our business, operations, and financial results.
We rely on our information technology systems for the effective operation of our business and for the secure maintenance and storage of confidential data relating to our business and third party businesses. Although we have implemented security controls to protect our information technology systems, experienced programmers or hackers may be able to penetrate our security controls, and develop and deploy viruses, worms and other malicious software programs that compromise our confidential information or that of third parties and cause a disruption or failure of our information technology systems. Any such compromise of our information technology systems could result in the unauthorized publication of our confidential business or proprietary information, result in the unauthorized release of customer, supplier or employee data, result in a violation of privacy or other laws, expose us to a risk of litigation, or damage our reputation. The cost and operational consequences of implementing further data protection measures either as a response to specific breaches or as a result of evolving risks, could be significant. In addition, our inability to use or access our information systems at critical points in time could adversely affect the timely and efficient operation of our business. Any delayed sales, significant costs or lost customers resulting from these technology failures could adversely affect our business, operations and financial results.
Third parties with which we conduct business, such as foundries, assembly and test contractors, and distributors, have access to certain portions of our sensitive data. In the event that these third parties do not properly safeguard our data that they hold, security breaches could result and negatively impact our business, operations and financial results.
Investor confidence may be adversely impacted if we are unable to comply with Section 404 of the Sarbanes-Oxley Act of 2002, and as a result, our stock price could decline.
We are subject to rules adopted by the Securities Exchange Commission, or SEC, pursuant to Section 404 of the Sarbanes-Oxley Act of 2002, or Sarbanes-Oxley Act, which require us to include in our Annual Report on Form 10-K our management’s report on, and assessment of the effectiveness of, our internal controls over financial reporting.
If we fail to maintain the adequacy of our internal controls, there is a risk that we will not comply with all of the requirements imposed by Section 404. Moreover, effective internal controls, particularly those related to revenue recognition, are necessary for us to produce reliable financial reports and are important to helping prevent financial fraud. Any of these possible outcomes could result in an adverse reaction in the financial marketplace due to a loss of investor confidence in the reliability of our consolidated financial statements and could result in investigations or sanctions by the SEC, the New York Stock Exchange, or NYSE, or other regulatory authorities or in stockholder litigation. Any of these factors ultimately could harm our business and could negatively impact the market price of our securities. Ineffective control over financial reporting could also cause investors to lose confidence in our reported financial information, which could adversely affect the trading price of our common stock.
Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives. However, our management, including our principal executive officer and principal financial officer, does not expect that our disclosure controls and procedures will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected.

29


Our products must conform to industry standards in order to be accepted by end users in our markets.
Generally, our products comprise only a part of a communications device. All components of these devices must uniformly comply with industry standards in order to operate efficiently together. We depend on companies that provide other components of the devices to support prevailing industry standards. Many of these companies are significantly larger and more influential in driving industry standards than we are. Some industry standards may not be widely adopted or implemented uniformly, and competing standards may emerge that may be preferred by our customers or end users. If larger companies do not support the same industry standards that we do, or if competing standards emerge, market acceptance of our products could be adversely affected, which would harm our business.
Products for communications applications are based on industry standards that are continually evolving. Our ability to compete in the future will depend on our ability to identify and ensure compliance with these evolving industry standards. The emergence of new industry standards could render our products incompatible with products developed by other suppliers. As a result, we could be required to invest significant time and effort and to incur significant expense to redesign our products to ensure compliance with relevant standards. If our products are not in compliance with prevailing industry standards for a significant period of time, we could miss opportunities to achieve crucial design wins. We may not be successful in developing or using new technologies or in developing new products or product enhancements that achieve market acceptance. Our pursuit of necessary technological advances may require substantial time and expense.
Risks Relating to Our Class A Common Stock
The dual class structure of our common stock as contained in our charter documents will have the effect of allowing our founders, executive officers, employees and directors and their affiliates to limit your ability to influence corporate matters that you may consider unfavorable.
We sold Class A common stock in our initial public offering. Our founders, executive officers, directors and their affiliates and employees hold shares of our Class B common stock, which is not publicly traded. Until March 29, 2017, the dual class structure of our common stock will have the following effects with respect to the holders of our Class A common stock:
allows the holders of our Class B common stock to have the sole right to elect two management directors to the Board of Directors;
with respect to change of control matters, allows the holders of our Class B common stock to have ten votes per share compared to the holders of our Class A common stock who will have one vote per share on these matters; and
with respect to the adoption of or amendments to our equity incentive plans, allows the holders of our Class B common stock to have ten votes per share compared to the holders of our Class A common stock who will have one vote per share on these matters, subject to certain limitations.
Thus, our dual class structure will limit your ability to influence corporate matters, including with respect to transactions involving a change of control, and, as a result, we may take actions that our stockholders do not view as beneficial, which may adversely affect the market price of our Class A common stock. In addition to the additional voting rights granted to holders of our Class B common stock, which is held principally by certain of our executive officers and founders, we have entered change of control agreements with our executive officers, which could have an adverse effect on a third party’s willingness to consider acquiring us, either because it may be more difficult to retain key employees with change of control benefits or because of the incremental cost associated with these benefits.
The concentration of our capital stock ownership with our founders will limit your ability to influence corporate matters and their interests may differ from other stockholders.
As of December 31, 2015, our founders who are existing employees of the Company, including our Chairman, President and Chief Executive Officer, Dr. Seendripu, together control approximately 10% of our outstanding capital stock, representing approximately 49% of the voting power of our outstanding capital stock with respect to change of control matters and the adoption of or amendment to our equity incentive plans. Dr. Seendripu and the other founders therefore have significant influence over our management and affairs and over all matters requiring stockholder approval, including the election of two Class B directors and significant corporate transactions, such as a merger or other sale of MaxLinear or its assets, for the foreseeable future.

Our management team may use our available cash, cash equivalents, and liquid investment assets in ways with which you may not agree or in ways which may not yield a return.
We use our cash, cash equivalents, and liquid investment assets for general corporate purposes, including working capital. We may also use a portion of these assets to acquire complementary businesses, products, services or technologies. Our management has considerable discretion in the application of our cash, cash equivalents, and investment resources, and you will not have the opportunity to assess whether these liquid assets are being used in a manner that you deem best to maximize your return. We may use our available resources for corporate purposes that do not increase our operating results or market value. In addition, our cash, cash equivalents, and liquid investment resources may be placed in investments that do not produce significant income or that may lose value
Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us more difficult, limit attempts by our stockholders to replace or remove our current management and limit the market price of our Class A common stock.
Provisions in our certificate of incorporation and bylaws, as amended and restated, may have the effect of delaying or preventing a change of control or changes in our management. These provisions provide for the following:
authorize our Board of Directors to issue, without further action by the stockholders, up to 25,000,000 shares of undesignated preferred stock;
require that any action to be taken by our stockholders be effected at a duly called annual or special meeting and not by written consent;
specify that special meetings of our stockholders can be called only by our Board of Directors, our Chairman of the Board of Directors, our President or by unanimous written consent of our directors appointed by the holders of Class B common stock;
establish an advance notice procedure for stockholder approvals to be brought before an annual meeting of our stockholders, including proposed nominations of persons for election to our Board of Directors;
establish that our Board of Directors is divided into three classes, Class I, Class II and Class III, with each class serving staggered terms and with one Class B director being elected to each of Classes II and III;
provide for a dual class common stock structure, which provides our founders, current investors, executives and employees with significant influence over all matters requiring stockholder approval, including the election of directors and significant corporate transactions, such as a merger or other sale of our Company or its assets;
provide that our directors may be removed only for cause;
provide that vacancies on our Board of Directors may be filled only by a majority of directors then in office, even though less than a quorum, other than any vacancy in the two directorships reserved for the designees of the holders of Class B common stock, which may be filled only by the affirmative vote of the holders of a majority of the outstanding Class B common stock or by the remaining director elected by the Class B common stock (with the consent of founders holding a majority in interest of the Class B common stock over which the founders then exercise voting control);
specify that no stockholder is permitted to cumulate votes at any election of directors; and
require supermajority votes of the holders of our common stock to amend specified provisions of our charter documents.
These provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our Board of Directors, which is responsible for appointing the members of our management. In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which generally prohibits a Delaware corporation from engaging in any of a broad range of business combinations with any “interested” stockholder for a period of three years following the date on which the stockholder became an “interested” stockholder.

31


Our share price may be volatile as a result of limited trading volume and other factors.
Our shares of Class A common stock began trading on the New York Stock Exchange in March 2010. An active public market for our shares on the New York Stock Exchange may not be sustained. In particular, limited trading volumes and liquidity may limit the ability of stockholders to purchase or sell our common stock in the amounts and at the times they wish. Trading volume in our Class A common stock tends to be modest relative to our total outstanding shares, and the price of our Class A common stock may fluctuate substantially (particularly in percentage terms) without regard to news about us or general trends in the stock market. An inactive market may also impair our ability to raise capital to continue to fund operations by selling shares and may impair our ability to acquire other companies or technologies by using our shares as consideration.
In addition, the trading price of our Class A common stock could become highly volatile and could be subject to wide fluctuations in response to various factors, some of which are beyond our control. These factors include those discussed in this “Risk Factors” section of this Annual Report on Form 10-K and others such as:
actual or anticipated fluctuations in our financial condition and operating results;
overall conditions in the semiconductor market;
addition or loss of significant customers;
changes in laws or regulations applicable to our products;
actual or anticipated changes in our growth rate relative to our competitors;
announcements of technological innovations by us or our competitors;
announcements by us or our competitors of significant acquisitions, strategic partnerships, joint ventures or capital commitments;
additions or departures of key personnel;
competition from existing products or new products that may emerge;
issuance of new or updated research or reports by securities analysts;
fluctuations in the valuation of companies perceived by investors to be comparable to us;
disputes or other developments related to proprietary rights, including patents, litigation matters and our ability to obtain intellectual property protection for our technologies;
the recently completed acquisition of Entropic may not be accretive and may cause dilution to our earnings per shares;
announcement or expectation of additional financing efforts;
sales of our Class A or Class B common stock by us or our stockholders;
share price and volume fluctuations attributable to inconsistent trading volume levels of our shares; and
general economic and market conditions.
Furthermore, the stock markets recently have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equity securities of many companies. These fluctuations often have been unrelated or disproportionate to the operating performance of those companies. These broad market and industry fluctuations, as well as general economic, political and market conditions such as recessions, interest rate changes or international currency fluctuations, may negatively impact the market price of our Class A common stock. In the past, companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. We may be the target of this type of litigation in the future. Securities litigation against us could result in substantial costs and divert our management’s attention from other business concerns, which could seriously harm our business.
If securities or industry analysts do not publish research or reports about our business, or publish negative reports about our business, especially due to our dual-class voting structure, our share price and trading volume could decline.

32


The trading market for our Class A common stock depends in part on the research and reports that securities or industry analysts publish about us or our business, especially with respect to our unique dual-class voting structure as to the election of directors, change of control matters and matters related to our equity incentive plans. We do not have any control over these analysts. If one or more of the analysts who cover us downgrade our shares or change their opinion of our shares, our share price would likely decline. If one or more of these analysts cease coverage of our Company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which could cause our share price or trading volume to decline.
Future sales of our Class A common stock in the public market could cause our share price to decline.
Sales of a substantial number of shares of our Class A common stock in the public market, or the perception that these sales might occur, could depress the market price of our Class A common stock and could impair our ability to raise capital through the sale of additional equity securities. As of December 31, 2015, we had 55.7 million shares of Class A common stock and 6.7 million shares of Class B common stock outstanding.
All shares of Class A common stock are freely tradable without restrictions or further registration under the Securities Act of 1933, as amended, or the Securities Act, except for any shares held by our affiliates as defined in Rule 144 under the Securities Act.
We have filed registration statements on Form S-8 under the Securities Act to register 18.9 million shares of our Class A common stock for issuance under our 2010 Equity Incentive Plan and 2010 Employee Stock Purchase Plan in addition to 3.2 million awards that were assumed and remain outstanding in connection with the Entropic acquisition. These shares may be freely sold in the public market upon issuance and once vested, subject to other restrictions provided under the terms of the applicable plan and/or the option agreements entered into with option holder.
Our Executive Incentive Bonus Plan permits the settlement of awards under the plan in the form of shares of its Class A common stock. For the 2013 performance period, actual awards under the Executive Incentive Bonus Plan were settled in Class A common stock issued under our 2010 Equity Incentive Plan, as amended, with the number of shares issuable to plan participants determined based on the closing sales price of our Class A common stock as determined in trading on the New York Stock Exchange on May 9, 2014. Additionally, we settled all bonus awards for all other employees for the 2013 performance period in shares of its Class A common stock. We issued 0.6 million shares of our Class A common stock for the 2013 performance period upon settlement of the bonus awards on May 9, 2014. We issued 0.2 million shares of our Class A common stock for the 2014 performance period upon settlement of the bonus awards on May 14, 2015. We issued 0.3 million shares of our Class A common stock for the January 1, 2015 to June 30, 2015 performance period upon settlement of the bonus awards on August 20, 2015. We expect to issue shares of our Class A common stock for the July 1, 2015 to December 31, 2015 performance period upon settlement of the bonus awards in May 2016.These shares may be freely sold in the public market immediately following the issuance of such shares and the issuance of such shares may have an adverse effect on our share price once they are issued.
We do not intend to pay dividends for the foreseeable future.
We have never declared or paid any cash dividends on our common stock and do not intend to pay any cash dividends in the foreseeable future. We anticipate that we will retain all of our future earnings for use in the development of our business and for general corporate purposes. Any determination to pay dividends in the future will be at the discretion of our Board of Directors. Accordingly, investors must rely on sales of their Class A common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investments.
Risks Relating to Our Acquisition of Entropic
Actual financial and operating results could differ materially from any expectations or guidance provided by us concerning future results, including (without limitation) expectations or guidance with respect to the financial impact of any cost savings and other potential synergies resulting from our acquisition of Entropic.
We currently expect to continue realizing material cost savings and other synergies as a result of our acquisition of Entropic, and as a result, we currently believe that the acquisition will continue to be accretive to our earnings per share, excluding upfront non-recurring charges, transaction related expenses, and the amortization of purchased intangible assets. The expectations and guidance we have provided with respect to the potential financial impact of the acquisition are subject to numerous assumptions, however, including assumptions derived from our diligence efforts concerning the status of and prospects for Entropic’s business, and assumptions relating to the near-term prospects for the semiconductor industry generally

33


and the markets for the legacy Entropic products in particular. Additional assumptions we have made relate to numerous matters, including (without limitation) the following:
projections of future revenues in the legacy Entropic businesses;
the anticipated financial performance of legacy Entropic products and products currently in development;
anticipated cost savings and other synergies associated with the acquisition, including potential revenue synergies;
the amount of goodwill and intangibles that will result from the acquisition;
certain other purchase accounting adjustments that we have recorded in our financial statements in connection with the acquisition;
acquisition costs, including restructuring charges and transactions costs payable to our financial, legal, and accounting advisors; and
our ability to maintain, develop, and deepen relationships with customers of the legacy Entropic business.
We cannot provide any assurances with respect to the accuracy of our assumptions, including our assumptions with respect to future revenues or revenue growth rates, if any, of the legacy Entropic business, and we cannot provide assurances with respect to our ability to realize further cost savings. Risks and uncertainties that could cause our actual results to differ materially from currently anticipated results include, but are not limited to, risks relating to our ability to integrate the legacy Entropic business successfully; currently unanticipated additional incremental costs that we may incur in connection with integrating the two companies; risks relating to our ability to continue to realize incremental revenues from the acquisition in the amounts that we currently anticipate; risks relating to the willingness of legacy Entropic customers and other partners to continue to conduct business with MaxLinear; and numerous risks and uncertainties that affect the semiconductor industry generally and the markets for our products and those of the legacy Entropic business specifically. Any failure to integrate the legacy Entropic business successfully and to continue to realize the financial benefits we currently anticipate from the acquisition would have a material adverse impact on our future operating results and financial condition and could materially and adversely affect the trading price or trading volume of our Class A common stock.
Failure to integrate our business and operations successfully with those of Entropic in the expected time-frame or otherwise may adversely affect our operating results and financial condition.
We do not have a substantial history of acquiring other companies and had never pursued an acquisition of the size and complexity of Entropic. The success of the acquisition of Entropic depends, in substantial part, on our ability to integrate Entropic’s business and operations successfully with those of MaxLinear and to realize fully the anticipated benefits and potential synergies from combining our companies, including, among others, cost savings from eliminating duplicative functions; operational efficiencies in our respective supply chains and in research and development investments; and revenue growth resulting from the addition of Entropic’s product portfolio. If we are unable to achieve these objectives, the anticipated benefits and potential synergies from the acquisition may not be realized fully, or may take longer to realize than expected. Any failure to timely realize these anticipated benefits would have a material adverse effect on our business, operating results, and financial condition.
We completed our acquisition of Entropic in April 2015. While we believe the integration process is substantially complete, we cannot ensure that remaining 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 acquisition and have a material adverse effect on our business, operating results, and financial condition.
Our business relationships, including customer relationships, and those of Entropic may be subject to disruption due to uncertainty associated with the acquisition.
In response to the completion of the acquisition, customers, vendors, licensors, and other third parties with whom we do business or Entropic did business or otherwise have relationships may experience uncertainty associated with the acquisition, and this uncertainty could materially affect their decisions with respect to existing or future business relationships with us. Moreover, with respect to Entropic’s prior acquisition of certain television and set-top box assets from Trident Microsystems, Inc., or Trident, we were unable to conduct substantial diligence with respect to certain licenses and intellectual property rights

34


because Entropic acquired these assets through Trident’s bankruptcy proceedings. As a result, we are in many instances unable to evaluate the impact of the acquisition on certain assumed contract rights and obligations, including intellectual property rights.
These business relationships may be subject to disruption as customers and others may elect to delay or defer purchase or design-win decisions or switch to other suppliers due to the uncertainty about the direction of our offerings, any perceived unwillingness on our part to support existing legacy Entropic products, or any general perceptions by customers or other third parties that impute operational or business challenges to us arising from the acquisition. In addition, customers or other third parties may attempt to negotiate changes in existing business relationships, which may result in additional obligations imposed on us. These disruptions could have a material adverse effect on our business, operating results, and financial condition. Any loss of customers, customer products, design win opportunities, or other important strategic relationships could have a material adverse effect on our business, operating results, and financial condition and could have a material and adverse effect on the trading price or trading volume of our Class A common stock.
We have incurred and expect to continue to incur substantial expenses related to the integration of MaxLinear and Entropic.
We have incurred and expect to continue to incur substantial expenses in connection with integrating the operations, technologies, and business systems of MaxLinear and Entropic. Business systems integration between the two companies requires, and we expect it to continue to require into the foreseeable future, substantial management attention, including integration of information management, purchasing, accounting and finance, sales, and regulatory compliance functions. Numerous factors, many of which, are beyond our control, could affect the total cost or the timing of expected integration expenses. Moreover, many of the expenses that will be incurred are by their nature difficult to estimate accurately at the present time. These expenses could reduce the savings that we expect to achieve from the elimination of duplicative expenses and the realization of economies of scale and cost savings related to the integration of the businesses. These integration expenses have resulted in MaxLinear’s taking significant charges against earnings following the completion of the acquisition.
We have recorded goodwill that could become impaired and adversely affect our future operating results.
The acquisition is accounted for as an acquisition by MaxLinear in accordance with accounting principles generally accepted in the United States. Under the acquisition method of accounting, the assets and liabilities of Entropic have been recorded, as of completion, at their respective fair values and added to our assets and liabilities. Our reported financial condition and results of operations after completion of the acquisition reflect Entropic’s balances and results but are not restated retroactively to reflect the historical financial position or results of operations of Entropic for periods prior to the acquisition. As a result, comparisons of future results against prior period results will be more difficult for investors.
Under the acquisition method of accounting, the total purchase price is allocated to Entropic’s tangible assets and liabilities and identifiable intangible assets based on their fair values as of the date of completion of the acquisition. The excess of the purchase price over those fair values is recorded as goodwill. The acquisition has resulted in the creation of goodwill based upon the application of the acquisition method of accounting. To the extent the value of goodwill or intangibles becomes impaired, we may be required to incur material charges relating to such impairment. Any such impairment charge could have a material impact on our operating results in future periods, and the announcement of a material impairment could have an adverse effect on the trading price and trading volume of our Class A common stock. For example, in the quarter ended December 31, 2015, we recognized IPR&D impairment losses of $21.6 million related principally to acquired Entropic assets. As of December 31, 2015, our balance sheet reflected goodwill of $49.8 million, and we could recognize impairment charges in the future.

ITEM 3.
LEGAL PROCEEDINGS
Entropic Communications Merger Litigation
The Delaware Actions
Beginning on February 9, 2015, eleven stockholder class action complaints (captioned Langholz v. Entropic Communications, Inc., et al., C.A. No. 10631-VCP (filed Feb. 9, 2015); Tomblin v. Entropic Communications, Inc., C.A. No. 10632-VCP (filed Feb. 9, 2015); Crill v. Entropic Communications, Inc., et al., C.A. No. 10640-VCP (filed Feb. 11, 2015); Wohl v. Entropic Communications, Inc., et al., C.A. No. 10644-VCP (filed Feb. 11, 2015); Parshall v. Entropic Communications, Inc., et al., C.A. No. 10652-VCP (filed Feb. 12, 2015); Saggar v. Padval, et al., C.A. No. 10661-VCP (filed Feb. 13, 2015); Iyer v. Tewksbury, et al., C.A. No. 10665-VCP (filed Feb. 13, 2015); Respler v. Entropic Communications, Inc., et al., C.A. No. 10669-VCP (filed Feb. 17, 2015); Gal v. Entropic Communications, Inc., et al., C.A. No. 10671-VCP (filed Feb. 17, 2015); Werbowsky v. Padval, et al., C.A. No. 10673-VCP (filed Feb. 18, 2015); and Agosti v. Entropic Communications, Inc., C.A. No. 10676-VCP (filed Feb. 18, 2015)) were filed in the Court of Chancery of the State of Delaware on behalf of a putative class of Entropic Communications, Inc. stockholders. The complaints name Entropic, the board of directors of Entropic, MaxLinear, Excalibur Acquisition Corporation, and Excalibur Subsidiary, LLC as defendants. The complaints generally allege that, in connection with the proposed acquisition of Entropic by MaxLinear, the individual defendants breached their fiduciary duties to Entropic stockholders by, among other things, purportedly failing to take steps to maximize the value of Entropic to its stockholders and agreeing to allegedly preclusive deal protection devices in the merger agreement. The complaints further allege that Entropic, MaxLinear, and/or the merger subsidiaries aided and abetted the individual defendants in the alleged breaches of their fiduciary duties. The complaints seek, among other things, an order enjoining the defendants from consummating the proposed transaction, an order declaring the merger agreement unlawful and unenforceable, in the event that the proposed transaction is consummated, an order rescinding it and setting it aside or awarding rescissory damages to the class, imposition of a constructive trust, damages, and/or attorneys’ fees and costs.
On March 27, 2015, plaintiffs Ankur Saggar, Jon Werbowsky, and Angelo Agosti filed an amended class action complaint. Also on March 27, 2015, plaintiffs Martin Wohl and Jeffrey Park filed an amended class action complaint. On April 1, 2015, plaintiff Mark Respler filed an amended class action complaint.
On April 16, 2015, the Court entered an order consolidating the Delaware actions, captioned In re Entropic Communications, Inc. Consolidated Stockholders Litigation, C.A. No. 10631-VCP (the “Consolidated Action”). The April 16, 2015 order appointed plaintiffs Rama Iyer and Jon Werbowsky as Co-Lead Plaintiffs and designated the amended complaint filed by plaintiffs Ankur Saggar, Jon Werbowsky, and Angelo Agosti as the operative complaint (the “Amended Complaint”).
The Amended Complaint names as defendants Entropic, the board of directors of Entropic, the Company, Excalibur Acquisition Corporation, and Excalibur Subsidiary, LLC. The Amended Complaint generally alleges that, in connection with the proposed acquisition of Entropic by the Company, the individual defendants breached their fiduciary duties to Entropic stockholders by, among other things, purportedly failing to maximize the value of Entropic to its stockholders, engaging in a purportedly unfair and conflicted sale process, agreeing to allegedly preclusive deal protection devices in the merger agreement, and allegedly misrepresenting and/or failing to disclose all material information in connection with the proposed transaction. The Amended Complaint further alleges that the Company and the merger subsidiaries aided and abetted the individual defendants in the alleged breaches of their fiduciary duties. The Amended Complaint seeks, among other things: an order declaring the merger agreement unlawful and unenforceable, an order rescinding, to the extent already implemented, the merger agreement, an order enjoining defendants from consummating the proposed transaction, imposition of a constructive trust, and attorneys’ and experts’ fees and costs.
On April 24, 2015, the parties to the Consolidated Action entered into a memorandum of understanding regarding a proposed settlement of the Delaware actions. The proposed settlement is subject to negotiation of the settlement papers by the parties and is subject to court approval after notice and an opportunity to object is provided to the proposed settlement class. There can be no assurance that the parties will reach agreement regarding the final terms of the settlement agreement or that the Court of Chancery will approve the settlement.

Based on the above, we have determined that an unfavorable outcome is probable or reasonably possible; or determined that the amount or range of any possible loss is reasonably estimable. The reasonably estimable loss is not material.
CrestaTech Litigation
On January 21, 2014, CrestaTech Technology Corporation, or CrestaTech, filed a complaint for patent infringement against us in the United States District Court of Delaware (the “District Court Litigation”). In its complaint, CrestaTech alleges that we infringe U.S. Patent Nos. 7,075,585 (the “’585 Patent”) and 7,265,792. In addition to asking for compensatory damages, CrestaTech alleges willful infringement and seeks a permanent injunction. CrestaTech also names Sharp Corporation, Sharp Electronics Corp. and VIZIO, Inc. as defendants based upon their alleged use of our television tuners. On January 28, 2014, CrestaTech filed a complaint with the U.S. International Trade Commission, or ITC, again naming, among others, us, Sharp, Sharp Electronics, and VIZIO (“the “ITC Investigation”). On May 16, 2014 the ITC granted CrestaTech’s motion to file an amended complaint adding six OEM Respondents, namely, SIO International, Inc., Hon Hai Precision Industry Co., Ltd., Wistron Corp., Wistron Infocomm Technology (America) Corp., Top Victory Investments Ltd. and TPV International (USA), Inc. (collectively, with us, Sharp and VIZIO, the “Company Respondents”). CrestaTech’s ITC complaint 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 the Company’s accused products that CrestaTech alleges 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 December 1-5, 2014, the ITC held a trial in the ITC Investigation. On February 27, 2015, the Administrative Law Judge issued a written Initial Determination (“ID”), ruling that the Company Respondents do not violate Section 1337 in connection with CrestaTech’s asserted patents because CrestaTech failed to satisfy the economic prong of the domestic industry requirement pursuant to Section 1337(a)(2). In addition, the ID stated that certain of our television tuners and televisions incorporating those tuners manufactured and sold by certain customers infringe three claims of the ‘585 Patent, and these three claims were not determined to be invalid. On April 30, 2015, the ITC issued a notice indicating that it intended to review portions of the ID finding no violation of Section 1337, including the ID’s findings of infringement with respect to, and validity of, the ‘585 Patent, and the ID’s finding that CrestaTech failed to establish the existence of a domestic industry within the meaning of Section 1337.
The ITC has subsequently issued its opinion, which terminated its investigation. The opinion affirmed the findings of the administrative law judge that no violation of Section 1337 had occurred because CrestaTech had failed to establish the economic prong of the domestic industry requirement. The ITC also affirmed the administrative law judge's finding of infringement with respect to the three claims of the '585 Patent that were not held to be invalid. On November 30, 2015, CrestaTech filed an appeal of the ITC decision with the United States Court of Appeals for the Federal Circuit (the "Federal Circuit").
The District Court Litigation remains stayed pending resolution of the appeal to the ITC. In addition, we have filed four petitions for inter partes review ("IPR") by the US Patent Office of the two CrestaTech patents asserted against us. The Patent Trial and Appeal Board (“PTAB”) did not institute two of these IPRs as being redundant to IPRs filed by another party that are already underway for the same CrestaTech patent.  The remaining two petitions were instituted or instituted-in-part and, together with the IPRs filed by third parties, there are currently six IPR proceedings filed involving the two CrestaTech patents asserted against us.  In October 2015, the PTAB issued final decisions in two of the six IPR proceedings, holding that all of the reviewed claims are unpatentable. Included in these decisions was one of the three claims mentioned above. CrestaTech is appealing the PTAB’s decisions at the Federal Circuit.
We cannot predict the outcome of any appeal by CrestaTech, the District Court Litigation, or the IPRs. Any adverse determination in the District Court Litigation could have a material adverse effect on our business and operating results.

37


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

Our Class B common stock is not publicly traded. Each share of Class B common stock is convertible at any time at the option of the holder into one share of Class A common stock and in most instances automatically converts upon sale or other transfer.
Dividend Policy
We have never declared or paid cash dividends on our common stock. We currently intend to retain all available funds and any future earnings for use in the operation of our business and do not anticipate paying any dividends on our common stock in the foreseeable future. Any future determination to declare dividends will be made at the discretion of our Board of Directors and will depend on our financial condition, operating results, capital requirements, general business conditions and other factors that our Board of Directors may deem relevant.
Stock Performance Graph
Notwithstanding any statement to the contrary in any of our previous or future filings with the SEC, the following information relating to the price performance of our common stock shall not be deemed “filed” with the SEC or “Soliciting Material” under the Exchange Act, or subject to Regulation 14A or 14C, or to liabilities of Section 18 of the Exchange Act except to the extent we specifically request that such information be treated as soliciting material or to the extent we specifically incorporate this information by reference.
The graph below compares the cumulative total stockholder return on our Class A common stock with the cumulative total return on The NYSE Composite Index and The Philadelphia Semiconductor Index. The period shown commences on March 23, 2010 and ends on December 31, 2015, the end of our last fiscal year. The graph assumes an investment of $100 on March 23, 2010, and the reinvestment of any dividends. In addition, the graph assumes the value of our common stock on March 23, 2010 was the initial public offering price of $14.00 per share.

The comparisons in the graph below are required by the Securities and Exchange Commission and are not intended to forecast or be indicative of possible future performance of our common stock.
Recent Sales of Unregistered Securities
In the year ended December 31, 2015, we issued an aggregate of 0.2 million shares of our Class B common stock to certain employees upon the exercise of options awarded under our 2004 Stock Plan. We received aggregate proceeds of approximately $0.4 million in the year ended December 31, 2015 as a result of the exercise of these options. We believe these transactions were exempt from the registration requirements of the Securities Act in reliance on Rule 701 thereunder as transactions pursuant to compensatory benefit plans and contracts relating to compensation as provided under Rule 701. As of December 31, 2015, options to purchase an aggregate of 1.5 million shares of our Class B common stock remain outstanding. All issuances of shares of our Class B common stock pursuant to the exercise of these options will be made in reliance on Rule 701. All option grants made under the 2004 Stock Plan were made prior to the effectiveness of our initial public offering. No further option grants will be made under our 2004 Stock Plan.
None of the foregoing transactions involved any underwriters, underwriting discounts or commissions, or any public offering.
Each share of our Class B common stock is convertible at any time at the option of the holder into one share of our Class A common stock. In addition, each share of our Class B common stock will convert automatically into one share of Class A common stock upon any transfer, whether or not for value, except for certain transfers described in our certificate of incorporation.

ITEM 7.
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, and mixed-signal integrated circuits for cable and satellite broadband communications, the connected home, and for data center, metro, and long-haul fiber networks. Our high performance RF receiver products capture and process digital and analog broadband signals to be decoded for various applications. These products include both RF receivers and RF receiver systems-on-chip (SoCs), which incorporate our highly integrated radio system architecture and the functionality necessary to receive and demodulate broadband signals, and physical medium devices that provide a constant current source, current-to-voltage regulation, and data alignment and retiming functionality in optical interconnect applications. Through our acquisition of Entropic Communications, Inc., or Entropic, in April of 2015, we provide semiconductor solutions for the connected home, ranging from MoCA® (Multimedia over Coax Alliance) solutions that transform how traditional HDTV broadcast and Internet Protocol- (IP) based streaming video content is seamlessly, reliably, and securely delivered, processed, and distributed into and throughout the home. Our products enable the reception, distribution and display of broadband video and data content in a wide range of electronic devices, including Pay-TV operator set-top boxes and voice and data gateways, hybrid analog and digital televisions and consumer terrestrial set-top boxes, Direct Broadcast Satellite outdoor units, and optical modules for data center, metro, and long-haul transport network applications.
Our net revenue has grown from approximately $0.6 million in fiscal 2006 to $300.4 million in fiscal 2015. In fiscal 2015, our net revenue was derived primarily from sales of RF receivers and RF receiver systems-on-chip and MoCA connectivity solutions into operator voice and data modems and gateways and global analog and digital RF receiver products for analog and digital television applications. These analog and digital television applications include Direct Broadcast Satellite outdoor unit (DBS ODU) solutions, which consist of our translation switch (BTS) and channel stacking switch (CSS) products. These products simplify the installation required to support simultaneous reception of multiple channels from multiple satellites over a single cable. Our ability to achieve revenue growth in the future will depend, among other factors, on our ability to further penetrate existing markets; our ability to expand our target addressable markets by developing new and innovative products; and our ability to obtain design wins with device manufacturers, in particular manufacturers of set-top boxes, data modems, and gateways for the broadband service provider and Pay-TV industries, manufacturers selling into the Cable infrastructure market, and manufacturers of optical module and telecommunications infrastructure equipment.
Products shipped to Asia accounted for 91%, 94% and 93% of net revenue during the years ended December 31, 2015, 2014 and 2013, respectively. A significant but declining portion of these sales in Asia is through distributors. Although a large percentage of our products is shipped to Asia, we believe that a significant number of the systems designed by these customers and incorporating our semiconductor products are then sold outside Asia. For example, we believe revenue generated from sales of our digital terrestrial set-top box products during the years ended December 31, 2015, 2014 and 2013 related principally to sales to Asian set-top box manufacturers delivering products into Europe, Middle East, and Africa, or EMEA markets. Similarly, revenue generated from sales of our cable modem products during the years ended December 31, 2015, 2014 and 2013 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 significant portion of our net revenue has historically been generated by a limited number of customers. In the year ended December 31, 2015, two of our customers, Arris and Cisco, accounted for 41% of our net revenue, and our ten largest customers collectively accounted for 76% of our net revenue. In November 2015, Technicolor completed its purchase of Cisco’s connected devices business.  The revenue percentage did not include the 1% revenue percentage for Technicolor. In the year ended December 31, 2014, one of our customers, Arris, accounted for 31% of our net revenue, and our ten largest customers collectively accounted for 67% of our net revenue. In the year ended December 31, 2013, one of our customers, Arris, accounted for 28% of our net revenue, and our ten largest customers collectively accounted for 72% of our net revenue. For the years ended December 31, 2014 and 2013, sales to Arris as a percentage of revenue include sales to Motorola Home, which was acquired by Arris in April 2013. For certain customers, we sell multiple products into disparate end user applications such as cable modems and both cable and satellite cable 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 satellite operator gateway and DBS ODU sectors, a design-in can have a product life cycle of 24 months to 60 months and beyond.
On April 30, 2015, the Company completed its acquisition of Entropic. Pursuant to the terms of the merger agreement or merger agreements dated as of February 3, 2015, by and among Maxlinear, Entropic, and two wholly-owned subsidiaries of the Company, all of the Entropic outstanding shares were converted into the right to receive consideration consisting of cash and shares of our Class A common stock. We paid an aggregate of $111.1 million in cash and issued an aggregate of 20.4 million shares of our Class A common stock to the stockholders of Entropic. In addition, we assumed all outstanding Entropic stock options and unvested restricted stock units that were held by continuing service providers (as defined in the merger agreement). The Company used Entropic’s cash and cash equivalents to fund a significant portion of the cash portion of the merger consideration and, to a lesser extent, our own cash and cash equivalents.
Critical Accounting Policies and Estimates
Management’s discussion and analysis of our financial condition and results of operations is based upon our financial statements which are prepared in accordance with accounting principles that are generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities, related disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. We continually evaluate our estimates and judgments, the most critical of which are those related to revenue recognition, allowance for doubtful accounts, inventory valuation, income taxes and stock-based compensation. We base our estimates and judgments on historical experience and other factors that we believe to be reasonable under the circumstances. Materially different results can occur as circumstances change and additional information becomes known.
We believe that the following accounting policies 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.
Revenue Recognition
Revenue is generated from sales of our integrated circuits. We recognize revenue when all of the following criteria are met: 1) there is persuasive evidence that an arrangement exists, 2) delivery of goods has occurred, 3) the sales price is fixed or determinable and 4) collectability is reasonably assured. Title to product transfers to customers either when it is shipped to or received by the customer, based on the terms of the specific agreement with the customer.
Revenue is recorded based on the facts at the time of sale. Transactions for which we cannot reliably estimate the amount that will ultimately be collected at the time the product has shipped and title has transferred to the customer are deferred until

43


the amount that is probable of collection can be determined. Items that are considered when determining the amounts that will be ultimately collected are a customer’s overall creditworthiness and payment history, customer rights to return unsold product, customer rights to price protection, customer payment terms conditioned on sale or use of product by the customer, or extended payment terms granted to a customer.
A portion of our revenues are generated from sales made through distributors under agreements allowing for pricing credits and/or stock rotation rights of return. Revenues from sales through our distributors accounted for 13%, 28% and 29% of net revenue during the years ended December 31, 2015, 2014 and 2013, respectively. Pricing credits to our distributors may result from our price protection and unit rebate provisions, among other factors. These pricing credits and/or stock rotation rights prevent us from being able to reliably estimate the final sales price of the inventory sold and the amount of inventory that could be returned pursuant to these agreements. As a result, for sales through distributors, we have determined that it does not meet all of the required revenue recognition criteria at the time we deliver our products to distributors as the final sales price is not fixed or determinable.
For these distributor transactions, revenue is not recognized until product is shipped to the end customer and the amount that will ultimately be collected is fixed or determinable. Upon shipment of product to these distributors, title to the inventory transfers to the distributor and the distributor is invoiced, generally with 30 day terms. On shipments to our distributors where revenue is not recognized, we record a trade receivable for the selling price as there is a legally enforceable right to payment, relieving the inventory for the carrying value of goods shipped since legal title has passed to the distributor, and record the corresponding gross profit in our consolidated balance sheet as a component of deferred revenue and deferred profit, representing the difference between the receivable recorded and the cost of inventory shipped. Future pricing credits and/or stock rotation rights from our distributors may result in the realization of a different amount of profit included in our future consolidated statements of operations than the amount recorded as deferred profit in our consolidated balance sheets.
We record reductions in revenue for estimated pricing adjustments related to price protection agreements with our end customers in the same period that the related revenue is recorded. Price protection pricing adjustments are recorded at the time of sale as a reduction to revenue and an increase in our accrued liabilities. The amount of these reductions is based on specific criteria included in the agreements and other factors known at the time. We accrue 100% of potential price protection adjustments at the time of sale and do not apply a breakage factor. We de-recognize the accrual for unclaimed price protection amounts as specific programs contractually end or when we believe unclaimed amounts are no longer subject to payment and will not be paid. See Note 4 for a summary of our price protection activity.
Allowance for Doubtful Accounts
We perform ongoing credit evaluations of our customers and adjust credit limits based on each customers’ credit worthiness, as determined by our review of current credit information. We monitor collections and payments from our customers and maintain an allowance for doubtful accounts based upon our historical experience, our anticipation of uncollectible accounts receivable and any specific customer collection issues that we have identified. While our credit losses have historically been insignificant, we may experience higher credit loss rates in the future than we have in the past. Our receivables are concentrated in relatively few customers. Therefore, a significant change in the liquidity or financial position of any one significant customer could make collection of our accounts receivable more difficult, require us to increase our allowance for doubtful accounts and negatively affect our working capital.
Inventory Valuation
We assess the recoverability of our inventory based on assumptions about demand and market conditions. Forecasted demand is determined based on historical sales and expected future sales. Inventory is stated at the lower of cost or market. Cost approximates actual cost on a first-in, first-out basis and market reflects current replacement cost (e.g. net replacement value) which cannot exceed net realizable value or fall below net realizable value less an allowance for an approximately normal profit margin. We reduce our inventory to its lower of cost or market on a part-by-part basis to account for its obsolescence or lack of marketability. Reductions are calculated as the difference between the cost of inventory and its market value based upon assumptions about future demand and market conditions. Once established, these adjustments are considered permanent and are not revised until the related inventory is sold or disposed of. If actual market conditions are less favorable than those projected by management, additional inventory write-downs may be required that may adversely affect our operating results. If actual market conditions are more favorable, we may have higher gross profits when products are sold.
Production Masks
Production masks with alternative future uses or discernible future benefits are capitalized and amortized over their estimated useful life of two years. To determine if the production mask has alternative future uses or benefits, we evaluate risks

44


associated with developing new technologies and capabilities, and the related risks associated with entering new markets. Production masks that do not meet the criteria for capitalization are expensed as research and development costs.
Business Combinations
We apply the provisions of ASC 805, Business Combinations, in the accounting for our acquisitions. ASC 805 requires the us to recognize separately from goodwill the assets acquired and the liabilities assumed, at the acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While we use our best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date as well as contingent consideration, where applicable, our estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, we record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the consolidated statements of operations.
Costs to exit or restructure certain activities of an acquired company or our internal operations are accounted for as termination and exit costs pursuant to ASC 420, Exit or Disposal Cost Obligations, and are accounted for separately from the business combination. A liability for costs associated with an exit or disposal activity is recognized and measured at its fair value in the consolidated statement of operations in the period in which the liability is incurred. When estimating the fair value of facility restructuring activities, assumptions are applied regarding estimated sub-lease payments to be received, which can differ materially from actual results. This may require us to revise our initial estimates which may materially affect the results of operations and financial position in the period the revision is made.
For a given acquisition, we may identify certain pre-acquisition contingencies as of the acquisition date and may extend our review and evaluation of these pre-acquisition contingencies throughout the measurement period in order to obtain sufficient information to assess whether we include these contingencies as a part of the fair value estimates of assets acquired and liabilities assumed and, if so, to determine their estimated amounts.
If we cannot reasonably determine the fair value of a pre-acquisition contingency (non-income tax related) by the end of the measurement period, which is generally the case given the nature of such matters, we will recognize an asset or a liability for such pre-acquisition contingency if (i) it is probable that an asset existed or a liability had been incurred at the acquisition date and (ii) the amount of the asset or liability can be reasonably estimated. Subsequent to the measurement period, changes in estimates of such contingencies will affect earnings and could have a material effect on results of operations and financial position.
In addition, uncertain tax positions and tax related valuation allowances assumed in connection with a business combination are initially estimated as of the acquisition date. We reevaluate these items quarterly based upon facts and circumstances that existed as of the acquisition date with any adjustments to the preliminary estimates being recorded to goodwill if identified within the measurement period. Subsequent to the measurement period or final determination of the tax allowance’s or contingency’s estimated value, whichever comes first, changes to these uncertain tax positions and tax related valuation allowances will affect the provision for income taxes in the consolidated statement of operations and could have a material impact on the results of operations and financial position.
Goodwill and Intangible Assets
Goodwill is recorded as the difference, if any, between the aggregate consideration paid for an acquisition and the fair value of the acquired net tangible and intangible assets. Intangible assets represent purchased intangible assets including developed technology and in-process research and development, or IPR&D, and technologies acquired or licensed from other companies. Purchased intangible assets with definitive lives are capitalized and amortized over their estimated useful life. Technologies acquired or licensed from other companies are capitalized and amortized over the greater of the terms of the agreement, or estimated useful life, not to exceed three years. We capitalize IPR&D projects acquired as part of a business combination. On completion of each project, IPR&D assets are reclassified to developed technology and amortized over their estimated useful lives.
Impairment of Goodwill and Long-Lived Assets
Goodwill is the excess of the purchase price over the fair value of identifiable net assets acquired in business combinations accounted for under the purchase method. Goodwill is not amortized but is tested for impairment using a qualitative assessment, and subsequently the two-step method as needed. This involves comparing the fair value of each reporting unit, which we have determined to be the entity itself, with its carrying amount, including goodwill. If the fair value

45


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. We test by reporting unit, goodwill and other indefinite-lived intangible assets for impairment at October 31 or more frequently if we believe indicators of impairment exist.
During development, IPR&D is not subject to amortization and is tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. We review indefinite-lived intangible assets for impairment as of October 31, the date of our annual goodwill impairment review or whenever events or changes in circumstances indicate the carrying value may not be recoverable. Recoverability of indefinite-lived intangible assets is measured by comparing the carrying amount of the asset to the future discounted cash flows that asset is expected to generate. Once an IPR&D project is complete, it becomes a definite lived intangible asset and is evaluated for impairment in accordance with our policy for long-lived assets.
We regularly review the carrying amount of our long-lived assets, as well as the useful lives, to determine whether indicators of impairment may exist which warrant adjustments to carrying values or estimated useful lives. An impairment loss would be recognized when the sum of the expected future undiscounted net cash flows is less than the carrying amount of the asset. Should impairment exist, the impairment loss would be measured based on the excess of the carrying amount of the asset over the asset’s fair value.
Income Taxes
We provide for income taxes utilizing the asset and liability approach of accounting for income taxes. Under this approach, deferred taxes represent the future tax consequences expected to occur when the reported amounts of assets and liabilities are recovered or paid. The provision for income taxes generally represents income taxes paid or payable for the current year plus the change in deferred taxes during the year. Deferred taxes result from the differences between the financial and tax bases of our assets and liabilities and are adjusted for changes in tax rates and tax laws when changes are enacted. Valuation allowances are recorded to reduce deferred tax assets when a judgment is made that is considered more likely than not that a tax benefit will not be realized. A decision to record a valuation allowance results in an increase in income tax expense or a decrease in income tax benefit. If the valuation allowance is released in a future period, income tax expense will be reduced accordingly.
The calculation of tax liabilities involves dealing with uncertainties in the application of complex global tax regulations. The impact of an uncertain income tax position is recognized at the largest amount that is “more likely than not” to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. If the estimate of tax liabilities proves to be less than the ultimate assessment, a further charge to expense would result.
In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. We will continue to assess the need for a valuation allowance on the deferred tax asset by evaluating both positive and negative evidence that may exist. Any adjustment to the net deferred tax asset valuation allowance would be recorded in the income statement for the period that the adjustment is determined to be required.
Stock-Based Compensation
We measure the cost of employee services received in exchange for equity incentive awards, including stock options, employee stock purchase rights, restricted stock units and restricted stock awards based on the grant date fair value of the award. We use the Black-Scholes valuation model to calculate the fair value of stock options and employee stock purchase rights granted to employees. We calculate the fair value of restricted stock units and restricted stock awards based on the fair market value of our Class A common stock on the grant date. Stock-based compensation expense is recognized over the period during which the employee is required to provide services in exchange for the award, which is usually the vesting period. We recognize compensation expense over the vesting period using the straight-line method and classify these amounts in the statements of operations based on the department to which the related employee reports. We calculate the weighted-average expected life of options using the simplified method as prescribed by guidance provided by the Securities and Exchange Commission. This decision was based on the lack of historical data due to our limited number of stock option exercises under the 2010 Equity Incentive Plan. We will continue to assess the appropriateness of the use of the simplified method as we develop a history of option exercises.

46


We account for stock options issued to non-employees in accordance with authoritative guidance for equity based payments to non-employees. Stock options issued to non-employees are accounted for at their estimated fair value determined using the Black-Scholes option-pricing model. The fair value of options granted to non-employees is re-measured as they vest, and the resulting increase in value, if any, is recognized as expense during the period the related services are rendered. We calculate the fair value of restricted stock units issued to non-employees based on the fair market value of our Class A common stock on the grant date and the resulting stock-based compensation expense is recognized over the period during which the non-employee is required to provide services in exchange for the award, which is usually the vesting period.
Results of Operations
The following describes the line items set forth in our consolidated statements of operations.
Net Revenue. Net revenue is generated from sales of integrated radio frequency analog and mixed signal semiconductor solutions for broadband communication applications. A significant but declining portion of our end customers purchases products indirectly from us through distributors. Although we actually sell the products to, and are paid by, the distributors, we refer to these end customers as our customers.
Cost of Net Revenue. Cost of net revenue includes the cost of finished silicon wafers processed by third-party foundries; costs associated with our outsourced packaging and assembly, test and shipping; costs of personnel, including stock-based compensation, and equipment associated with manufacturing support, logistics and quality assurance; amortization of certain production mask costs; cost of production load boards and sockets; and an allocated portion of our occupancy costs.
Research and Development. Research and development expense includes personnel-related expenses, including stock-based compensation, new product engineering mask costs, prototype integrated circuit packaging and test costs, computer-aided design software license costs, intellectual property license costs, reference design development costs, development testing and evaluation costs, depreciation expense and allocated occupancy costs. Research and development activities include the design of new products, refinement of existing products and design of test methodologies to ensure compliance with required specifications. All research and development costs are expensed as incurred.
Selling, General and Administrative. Selling, general and administrative expense includes personnel-related expenses, including stock-based compensation, distributor and other third-party sales commissions, field application engineering support, travel costs, professional and consulting fees, legal fees, depreciation expense and allocated occupancy costs.
Impairment Losses. Impairment losses are attributed to the impairment charges to intangible assets.
Restructuring Charges. Restructuring charges consist of employee severance and stock compensation expenses, and lease and leasehold impairment charges related to our restructuring plan entered into as a result of our acquisition of Entropic, and an adjustment related to restructuring plan implemented by Entropic prior to acquisition.
Interest Income. Interest income consists of interest earned on our cash, cash equivalents and investment balances.
Other Income (Expense). Other income (expense) generally consists of income (expense) generated from non-operating transactions.
Provision (Benefit) for Income Taxes. We make certain estimates and judgments in determining income tax expense for financial statement purposes. These estimates and judgments occur in the calculation of certain tax assets and liabilities, which arise from differences in the timing of recognition of revenue and expenses for tax and financial statement purposes and the realizability of assets in future years.

Our acquisition of Entropic in April 2015 has changed the composition, breadth, and diversity of MaxLinear’s technology portfolio. In particular, MoCA technologies have expanded our technology platform in cable, satellite, and telecommunications applications, and analog channel stacking solutions have expanded our presence in Direct Broadcast Satellite outdoor unit applications. In addition, we increased our investment in new technology development targeting infrastructure markets, while reducing our investment in retail-oriented and legacy technologies such as terrestrial tuners, hybrid TV tuners, and legacy video processing technologies. As a result of these changes, we have realigned our revenue composition to reflect our strategic investment focus and platform presence. We have illustrated these changes with the market terms operator, infrastructure and other, and legacy video SoC.
Within the operator category, the primary revenue contributors are our broadband RF receivers, MoCA connectivity solutions, and analog and digital channel stacking satellite outdoor unit solutions. Within the infrastructure and other category, the primary revenue contributors are hybrid TV tuners and terrestrial set-top box TV tuners for digital television adapters, or DTAs, that are sold through retail channels, high-speed interconnect products for the data center, metro, and long haul markets, and access technologies for last mile high-speed data access and distribution solutions for multi-dwelling units. The legacy video SoC category includes video processing technologies used primarily in cable high definition digital-to-analog converters and other client IP devices; consistent with Entropic’s previously announced plans, MaxLinear is supporting existing product shipments in this market but does not plan to use its resources to expand the legacy SoC technology portfolio.

48


The increase in net revenue in the year ended December 31, 2015, as compared to the year ended December 31, 2014, was primarily due to $123.9 million of growth in operator applications, contributed primarily by analog channel-stacking, or aCSS, and MoCA products related to our Entropic acquisition, as well as organic growth across each of our other operator sub-categories. An increase of $45.5 million in our legacy video SoC products was attributable to our acquisition of Entropic. Declines in infrastructure and other revenues of $2.1 million were primarily driven by hybrid-TV and consumer digital-to-analog terrestrial set-top box applications, which offset growth in retail MoCA products related to our Entropic acquisition and high-speed interconnect products related to our Physpeed acquisition.
The increase in net revenue in the year ended December 31, 2014, as compared to the year ended December 31, 2013, was primarily due to $9.5 million of growth in operator applications, contributed primarily by growth in cable data product revenue and, to a lesser extent, growth in terrestrial set-top box and satellite gateway products, offset by a decline in cable video sales. An increase in infrastructure and other revenue of $4.0 million was driven by roughly equivalent dollar growth in hybrid-TV and consumer digital-to-analog terrestrial set-top box applications.

The decrease in gross profit percentages for the year ended December 31, 2015, as compared to the year ended December 31, 2014, was primarily due to revaluation of inventory amortization of $14.2 million and amortization of intellectual property costs of $4.2 million related to the Entropic acquisition. The gross margin decline was also driven by the significant increase in Entropic-related product revenue, which has historically generated lower gross margin than our previous corporate average.
The increase in gross profit percentages in the year ended December 31, 2014, as compared to the year ended December 31, 2013, was primarily due to the absence of production mask impairments of $1.1 million in the year ended December 31, 2014, which was offset by an increase in sales of lower margin products.
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.

The increase in research and development expense for the year ended December 31, 2015, as compared to the year ended December 31, 2014, was primarily due to an increase in headcount-related items (including stock-based compensation) of $16.6 million, and the combined increases in design tools, prototype, compensation to employees in relation to the Physpeed transaction, amortization, travel, and occupancy expenses of $11.9 million. In 2015, headcount-related items increased primarily due to increases in our average full-time-equivalent headcount compared to prior year. The non-headcount related increases are primarily due to increased project related design tools usage.
The increase in research and development expense for the year ended December 31, 2014, as compared to the year ended December 31, 2013, was primarily due to a $4.4 million increase in headcount-related items (including stock-based compensation) and combined increases in design tools and occupancy expenses of $1.5 million, offset by a decrease in performance based compensation of $1.4 million and prototype expenses of $1.0 million. In 2014, headcount-related items increased primarily due to increases in our average full-time-equivalent headcount compared to prior year. The non-headcount related increases are primarily due to increased project related design tools usage and several facilities relocation and facilities expansions in Bangalore, India and Carlsbad, California.

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

The increase in selling, general and administrative expense in the year ended December 31, 2015, as compared to the year ended December 31, 2014, was primarily due to the amortization of purchased intangible assets of $25.0 million and transaction costs of $5.4 million associated with our Entropic acquisition, an increase in headcount-related items (including stock-based compensation) of $5.1 million, and an increase in commission, outside services, professional fees, occupancy, and other expenses of $10.0 million while legal fees decreased $1.7 million. In 2015, headcount-related items increased primarily due to increases in our average full-time-equivalent headcount compared to prior year. The non-headcount related increases are primarily due our facilities expansion efforts.
The increase in selling, general and administrative expense in the year ended December 31, 2014, as compared to the year ended December 31, 2013, was primarily attributable to a $1.9 million increase in headcount-related items (including stock-based compensation) and combined increases in professional, consulting and outside services, travel-related, and occupancy expenses of $2.0 million, offset by a decrease in performance based compensation of $0.3 million and non-recurring legal expenses of $1.6 million. In 2014, headcount-related items increased primarily due to increases in our average full-time-equivalent headcount compared to prior year. The non-headcount related increases are primarily due to our acquisition of Physpeed and several facilities relocation and facilities expansions in Bangalore, India and Carlsbad, California. Non-recurring legal fees decreased due to the completion of our litigation with Silicon Laboratories in the prior year.
We expect selling, general and administrative expenses to increase in the future as we expand our sales and marketing organization to enable expansion into existing and new markets and continue to build our international administrative infrastructure.

The benefit for income taxes for the year ended December 31, 2015 was $0.6 million or approximately 1% of pre-tax loss compared to a benefit for income taxes of $1.7 million or approximately 19% of pre-tax loss for the year ended December 31, 2014. The provision for income taxes in the year ended December 31, 2013 was $0.4 million or approximately 3% of pre-tax loss.

The benefit for income taxes for the years ended December 31, 2015 and 2014 primarily relates to the release of valuation allowance in connection with the Entropic and Physpeed acquisitions in 2015 and 2014, respectively, partially offset by income taxes in foreign jurisdictions and accruals for tax contingencies. We continue to maintain a valuation allowance to offset the federal and California deferred tax assets as realization of such assets does not meet the more-likely-than-not threshold required under accounting guidelines. We will continue to assess the need for a valuation allowance on the deferred tax assets by evaluating positive and negative evidence that may exist. Until such time that we remove the valuation allowance against our federal and California deferred tax assets, our provision for income taxes will primarily consist of taxes associated with our foreign subsidiaries.Additionally, the Company completed the acquisition of Entropic in the second quarter of 2015. As a result of the acquisition, there was a valuation allowance release resulting in a tax benefit of $1.8 million. Furthermore, we do not incur expense or benefit in certain tax free jurisdictions in which we operate.
Income tax expense in the foreign jurisdictions in which we are subject to tax is expected to remain relatively constant due to the cost plus nature of these entities and the relatively consistent operating expenses in each jurisdiction. Fluctuations in world-wide income occur mostly outside of these jurisdictions and therefore have an insignificant effect on our provision for income taxes. We expect this relationship to continue until the time that we either recognize all or a portion of our federal and California deferred tax assets or implement changes to our global operations.
Liquidity and Capital Resources
As of December 31, 2015, we had cash and cash equivalents of $68.0 million, short- and long-term investments of $62.5 million, and net accounts receivable of $42.4 million.
Our primary uses of cash are to fund operating expenses, purchases of inventory and the acquisition of property and equipment. Cash used to fund operating expenses excludes the impact of non-cash items such as depreciation and stock-based compensation and is impacted by the timing of when we pay these expenses as reflected in the change in our outstanding accounts payable and accrued expenses.
Our primary sources of cash are cash receipts on accounts receivable from our shipment of products to distributors and direct customers. Aside from the growth in 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.

Cash Flows from Operating Activities
Net cash provided by operating activities was $55.0 million for the year ended December 31, 2015. Net cash provided by operating activities primarily consisted of $103.1 million in non-cash operating expenses, partially offset by $5.7 million in changes in operating assets and liabilities and a net loss of $42.3 million. Non-cash items included in net loss for the year ended December 31, 2015 included depreciation and amortization expense of $40.6 million, impairment charges on intangibles assets of $21.6 million, stock-based compensation of $19.3 million, amortization of inventory step-up of $14.2 million, impairment and restructuring on leases of $8.2 million and amortization of net investment premiums of $0.6 million, offset by deferred income taxes of $1.9 million.
Net cash provided by operating activities was $12.2 million for the year ended December 31, 2014. Net cash provided by operating activities consisted of $18.6 million in non-cash operating expenses and $0.7 million in changes in operating assets and liabilities, partially offset by a net loss of $7.0 million. Non-cash items included in net loss for the year ended December 31, 2014 included stock-based compensation of $15.0 million, depreciation and amortization expense of $5.1 million and amortization of net investment premiums of $0.7 million.
Net cash provided by operating activities was $12.9 million for the year ended December 31, 2013.  Net cash provided by operating activities primarily consisted of $6.9 million in changes in operating assets and liabilities and $18.7 million in non-cash operating expenses, partially offset by a net loss of $12.7 million. Non-cash items included in net loss for the year ended December 31, 2013 included depreciation and amortization expense of $3.7 million, amortization of net investment premiums of $1.0 million, stock-based compensation of $13.0 million, and impairment of long-lived assets of $1.2 million.
Cash Flows from Investing Activities
Net cash used in investing activities was $11.1 million for the year ended December 31, 2015. Net cash provided by investing activities consisted of $73.4 million in purchases of securities, $3.6 million used in our acquisition of Entropic, $3.0 million in purchases of property and equipment and $0.1 million used in the purchase of intangibles, offset by $69.0 million in maturities of securities.
Net cash used in investing activities was $17.5 million for the year ended December 31, 2014. Net cash used in investing activities consisted of $56.7 million in purchases of securities, $9.1 million cash used in the acquisition of Physpeed and $8.8 million in purchases of property and equipment, offset by $57.2 million in maturities of securities.

Net cash used in investing activities was $9.5 million for the year ended December 31, 2013. Net cash used in investing activities primarily consisted of $70.6 million in purchases of securities, $3.2 million in purchases of property and equipment and $1.0 million in purchases of intangibles, offset by $65.2 million in maturities of securities.
Cash Flows from Financing Activities
Net cash provided by financing activities was $4.0 million for the year ended December 31, 2015 consisted primarily of $10.0 million in net proceeds from issuance of common stock, offset by $5.1 million in minimum tax withholding paid on behalf of employees for restricted stock units, equity issuance costs of $0.7 million and repurchases of common stock of $0.1 million.
Net cash used in financing activities was $0.5 million for the year ended December 31, 2014 consisted primarily of $3.3 million in net proceeds from issuance of common stock, offset by $3.8 million in minimum tax withholding paid on behalf of employees for restricted stock units.
Net cash provided by financing activities was $1.3 million for the year ended December 31, 2013. Net cash provided by financing activities consisted primarily of proceeds from issuance of common stock of $2.6 million partially offset by $1.4 million in minimum tax withholding paid on behalf of employees for restricted stock units and payments on capital leases.
We believe that our $68.0 million of cash and cash equivalents and $62.5 million in short- and long-term investments at December 31, 2015 will be sufficient to fund our projected operating requirements for at least the next twelve months. Our cash and cash equivalents as of December 31, 2015 have been favorably affected by our implementation of an equity-based bonus program. In connection with that bonus program, in August 2015, we issued 0.3 million freely-tradable shares of our Class A common stock in settlement of bonus awards for the January 1, 2015 to June 30, 2015 performance period under our bonus plan. In May 2015, we issued 0.2 million freely-tradable shares of our Class A common stock in settlement of bonus awards for the fiscal 2014 performance period under our bonus plan. In May 2014, we issued 0.6 million freely-tradable shares of our Class A common stock in settlement of bonus awards for the fiscal 2013 performance period under our bonus plan. We expect to implement a similar equity-based plan for the second half of fiscal 2015, but our compensation committee retains discretion to effect payment in cash, stock, or a combination of cash and stock.
Notwithstanding the foregoing, we may need to raise additional capital or incur additional indebtedness to continue to fund our operations in the future. Our future capital requirements will depend on many factors, including our rate of revenue growth, the expansion of our engineering, sales and marketing activities, the timing and extent of our expansion into new territories, the timing of introductions of new products and enhancements to existing products, the continuing market acceptance of our products and potential material investments in, or acquisitions of, complementary businesses, services or technologies. Additional funds may not be available on terms favorable to us or at all. If we are unable to raise additional funds when needed, we may not be able to sustain our operations.
Warranties and Indemnifications
In connection with the sale of products in the ordinary course of business, we often make representations affirming, among other things, that our products do not infringe on the intellectual property rights of others, and agree to indemnify customers against third-party claims for such infringement. Further, our certificate of incorporation and bylaws require us to indemnify our officers and directors against any action that may arise out of their services in that capacity, and we have also entered into indemnification agreements with respect to all of our directors and certain controlling persons.
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 December 31, 2015, we were not involved in any unconsolidated SPE transactions.

ITEM 7A.
QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Foreign Currency Risk
To date, our international customer and vendor agreements have been denominated mostly in United States dollars. Accordingly, we have limited exposure to foreign currency exchange rates and do not enter into foreign currency hedging transactions. The functional currency of certain foreign subsidiaries is the local currency. Accordingly, the effects of exchange rate fluctuations on the net assets of these foreign subsidiaries’ operations are accounted for as translation gains or losses in accumulated other comprehensive income within stockholders’ equity. We do not believe that a change of 10% in such foreign currency exchange rates would have a material impact on our financial position or results of operations.
Interest Rate Risk
We had cash and cash equivalents of $68.0 million at December 31, 2015 which was held for working capital purposes. We do not enter into investments for trading or speculative purposes. We do not believe that we have any material exposure to changes in the fair value of these investments as a result of changes in interest rates due to their short-term nature. Declines in interest rates, however, will reduce future investment income.
Investments in fixed rate interest earning instruments carry a degree of interest rate risk. Fixed rate securities may have their market value adversely impacted due to rising interest rates. Due in part to these factors, our future investment income may fall short of expectations due to changes in interest rates.
Investments Risk
Our investments, consisting of U.S. Treasury and agency obligations and corporate notes and bonds, are stated at cost, adjusted for amortization of premiums and discounts to maturity. In the event that there are differences between fair value and cost in any of our available-for-sale securities, unrealized gains and losses on these investments are reported as a separate component of accumulated other comprehensive income (loss).

ITEM 9.

ITEM 9A.    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 Form 10-K, 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 Form 10-K. 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 Form 10-K.
Management’s Annual Report on Internal Controls over Financial Reporting
Our management, including our principal executive officer and principal financial officer, is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Our management, including our principal executive officer and principal financial officer, evaluated the effectiveness of our internal control over financial reporting based on criteria established in the Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based upon that evaluation, management concluded that our internal control over financial reporting was effective as of December 31, 2015. The effectiveness of our internal control over financial reporting as of December 31, 2015 has been audited by Ernst & Young LLP, an independent registered public accounting firm, and Ernst & Young LLP has issued a report on our internal control over financial reporting, as stated within their report which is included herein.
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 December 31, 2015 that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting. On April 30, 2015, we acquired Entropic and, as a result, we have been integrating the processes, systems and controls relating to Entropic into our existing system of internal control over financial reporting in accordance with our integration plans through the fiscal quarter ended December 31, 2015. As of December 31, 2015, we have substantially completed integrating the internal controls over financial reporting related to Entropic. There were no changes, except for the integration mentioned above, 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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The Board of Directors and Stockholders of MaxLinear, Inc.
We have audited MaxLinear, Inc.’s internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). MaxLinear, Inc.’s management is responsible for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit.
We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
In our opinion, MaxLinear, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2015, based on the COSO criteria.
    
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of MaxLinear, Inc. as of December 31, 2015 and 2014, and the related consolidated statements of operations, comprehensive loss, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2015 and the financial statement schedule listed in the Index at Item 15(a)(2) of MaxLinear, Inc. and our report dated February 17, 2016 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders of MaxLinear, Inc.
We have audited the accompanying consolidated balance sheets of MaxLinear, Inc. as of December 31, 2015 and 2014, and the related consolidated statements of operations, comprehensive loss, stockholders' equity and cash flows for each of the three years in the period ended December 31, 2015. Our audits also included the financial statement schedule listed in the Index at Item 15(a)(2). These financial statements and schedule are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.
In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of MaxLinear, Inc. at December 31, 2015 and 2014, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2015, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), MaxLinear, Inc.’s internal control over financial reporting as of December 31, 2015, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated February 17, 2016 expressed an unqualified opinion thereon.
