This summary is not complete and does not contain all of the information that you should consider before deciding whether to invest in our common stock. For a more complete understanding of our company and this offering, we encourage you to read and consider carefully the more detailed information contained in or incorporated by reference in this prospectus, including the information contained under the heading “Risk Factors” beginning on page 21 of this prospectus, and the information included in any free writing prospectus that we have authorized for use in connection with this offering.

Business Overview

We develop, manufacture and sell optoelectronic products that transmit, receive and switch high speed digital optical signals for communications networks. The percentage of our total revenue derived from our high speed products (100G and beyond) increased to 45% in the three months ended September 30, 2014, from 4% in the three months ended September 30, 2011, reaching $37.1 million of revenue in the three months ended September 30, 2014. We have recently agreed to acquire EMCORE Corporation’s ultra narrow line width laser product lines to add to our 100G product offerings. We also produce active and passive optoelectronic products for lower speed networks, including Access and 10G networks.

Our 100G and beyond products require our Advanced Hybrid Photonic Integration technology. We produce photonic integrated circuits (PICs) that comprise both arrayed and individual photonic functional elements using optimized materials systems and processes from our in-house Silicon, Indium Phosphide and Gallium Arsenide wafer fabrication. These individual PICs from different materials are then combined using our hybrid integration technology to make complete products, such as our Integrated Coherent Receiver (ICR) for 100G coherent transport applications.

According to Infonetics Research, Inc. (Infonetics), 100G networks are among the highest growth segments of the optical communications market, supporting the rapid expansion of backbone networks and accommodating increased mobile traffic. The high speed 100G and beyond market, which requires advanced photonic integration technology, is the core focus of our strategy.

Our Advanced Hybrid Photonic Integration technology progressively increases performance, reduces cost and reduces size of our products. These cost reductions and performance increases are required for the growth of network capacity.

As we penetrate the rapidly growing 100G market, we are reducing our product offerings for slower speeds that do not meet our profitability standards. We continually seek to drive down our cost of goods, and are implementing initiatives designed to reduce our infrastructure and operating expenses and to strengthen our balance sheet.

We sell our products to the world’s leading network equipment manufacturers, including Alcatel-Lucent SA, Ciena Corporation, Cisco Systems, Inc., and Huawei Technologies Co., Ltd. These four companies are among our largest customers and a focus of our strategy due to their leading market positions. According to Infonetics, these four companies supplied 70% of the 2013 world market for 100G coherent communications ports. These four companies accounted for 67% of our revenue in the nine months ended September 30, 2014.

We have research and development and wafer fabrication facilities in San Jose and Fremont, California and in Tokyo, Japan that coordinate with our research and development and manufacturing facilities in Dongguan, Shenzhen and Wuhan, China and Ottawa, Canada. We use proprietary design tools and design-for-manufacturing

techniques to align our design process with our precision nanoscale, vertically integrated manufacturing and testing. We believe we are one of the highest volume PIC manufacturers in the world and that we can further expand our manufacturing capacity to meet market needs.

In October 2011, we acquired Santur Corporation (Santur), a leading producer of tunable lasers and of 100G transceiver modules. Santur’s capabilities included array DFB (distributed feedback) lasers, silicon photonics and photonic integration of such active elements as lasers, modulators and photodiodes.

In March 2013, we acquired the optical component business unit of LAPIS Semiconductor Co., Ltd., located in Japan, now known as NeoPhotonics Semiconductor, which is a leading producer of high performance communications lasers, photodiodes and optical control electronic devices. NeoPhotonics Semiconductor was built over 30 years as part of OKI Electric, and earned a reputation as a leading developer and supplier of the highest speed optoelectronic devices. This business produces high speed EML lasers and photodiodes from Indium Phosphide, and semiconductor drivers and high sensitivity amplifiers from Gallium Arsenide.

In October 2014, we entered into an agreement with EMCORE Corporation (EMCORE) to acquire certain assets and assume certain liabilities of EMCORE’s tunable laser and transceiver product lines. We expect to complete this transaction by early January 2015, subject to customary closing conditions. We anticipate strong complementarity between EMCORE’s leading ultra narrow linewidth tunable lasers for the industry’s highest speed applications and our highest speed and most sensitive receiver products at speeds of 400G and beyond.

We believe our technology is well positioned to serve the highest speed and most demanding applications. These three acquisitions, together with other internal developments, and acquisitions conducted prior to 2011, continue our path spanning more than ten years to develop complete Advanced Hybrid Photonic Integration capabilities.

Industry Background

The realm of communications, having become almost entirely digital, has moved from electronic signals over copper wire to optical signals over thin glass fibers, which achieves the speed and capacity necessary for the current and future communications market.

Increasingly, the most ubiquitous data link to users is via mobile devices through broadband wireless access. Smartphones now incorporate the most sophisticated and powerful applications which were developed at great cost over the last four decades for consumer electronics. Originally priced in the $100s, or $1,000s or $10,000s for earlier computing platforms, these applications, when migrated onto smartphones, are usually priced at cents to a few dollars per application. As cost performance has improved for applications by many orders of magnitude over the four decades since the introduction of the personal computer, so too has end user hardware advanced many orders of magnitude in cost performance, while network data rates have also increased a comparable magnitude.

The new era of connectedness is increasingly universal and demands that the capacity of the digital communications networks must increase exponentially. Smartphones have emerged as the vehicle connecting the entire digital world, with more than one billion current smartphone users. Not only are more people connected to the mobile web, they are connecting at increasingly higher data rates requiring higher bandwidths. Wireless network deployments have progressed from second generation (2G) to third generation (3G) to fourth generation (4G/LTE) and can now provide end-user download speeds approaching 50 megabits per second. Fiber to the Home (FTTH) connections have also continued apace, with more than 100 million homes receiving such service, according to the FTTH Council, and with download speeds reaching as high as 1 Gbps.

Industry Growth Dynamics

The revolution in the power of low cost computing devices is associated with Moore’s Law, referring to an observation made by Intel co-founder Gordon Moore in 1965 that the number of transistors per square inch on integrated circuits had doubled every two years since their invention and a prediction that this trend would continue. In the domain of optical communications, a similar revolution, progressing at a similar rate, is driven by the increased speed, smaller size and lower cost achieved by photonic integration.

Bandwidth capacity of communications networks continues to expand at a rapid rate. According to Infonetics, total deployed telecom bandwidth capacity will grow at a compound annual growth rate of 32% from 2013 to 2018, reaching more than 50 petabytes per second in 2018. According to Infonetics, total deployed datacenter bandwidth capacity is expected to grow even faster, at a compound annual growth rate of 44% from 2013 to 2018 and reaching more than 900 petabytes per second in 2018.

According to Infonetics, datacom 100G transceiver revenue is projected to grow at a 29% compound annual growth rate from 2013 to 2018, reaching $1 billion in 2018. In contrast, revenue from slower speed products such as 10G datacom transceivers is forecast to grow at only a 2% compound annual growth rate from 2013 to 2018.

Revenue for 100G related telecom deployments in 2013 was approximately $1.9 billion representing 20% of all Wavelength Division Multiplexing (WDM) systems spending, according to Infonetics. The WDM 100G segment grew 207% in 2013 versus 2012. Slower speed segments such as 10G WDM declined 6.9% in 2013 versus 2012. According to Infonetics, overall optical network equipment spending in 2013 was approximately $12 billion.

Digital Optical Communications Market Structure

The digital optical communications market has two main sectors, telecom and datacom. The telecom sector includes the global backbone of Long Haul and Metro communications. It also includes local access links to end users. Telecom, with its historical background as a public utility, is driven by reliability, telecom communications protocols and standards, and the long life of its infrastructure capital investment. The service life objective for products used in telecom infrastructure historically has been 20 years.

The Long Haul telecom sector is the first adopter of the highest speed and most advanced communication links, which migrate over time into the Metro sector as costs are reduced such that they are economical in the shorter Metro network links, with its commensurate lower traffic densities prior to aggregation for Long Haul transport.

The datacom market can be described primarily as an “enterprise” market, in contrast to the historical public utility nature of the telecom market. In addition to the broad enterprise market, datacom also includes data centers and infrastructure for cloud based services. Companies, including Amazon, Apple, Facebook, Google and Microsoft, are increasing investments in very large datacenters as they implement cloud-based “big data” services that can be crowd-sourced and crowd-distributed, and that utilize machine-to-machine and inter-datacenter transactions to power the mobile web. Such very large datacenters are an emerging high growth market for “big pipes” using dedicated 100G and beyond digital optical connections from datacenter to datacenter, datacenter to telecommunications carrier and within datacenters.

Generations of hardware installations for datacom, such as server farms and “big data” network storage facilities, have relatively short lives, typically about five years, as computing and storage technology advances rapidly. Therefore, the datacom market for optoelectronic devices generates more rapid changes in form factors, energy efficiency and compactness than the telecom market.

The datacom market is often the most cost sensitive sector of digital optical communications, and therefore it begins to adopt leading edge speeds after those speeds penetrate the Metro sector of the telecom market segment.

From this market structure, it can be concluded that a technology leader must achieve a leadership position in the Long Haul telecom sector as the basis for commercializing the most advanced technology.

Digital Optical Communications Network Equipment

The structure of the industry that supplies the network equipment for the telecom digital optical communications network has largely concentrated down to nine leading vendors: Alcatel-Lucent, Ciena, Cisco, Coriant (including Tellabs, which was acquired by Coriant in 2013), Fujitsu Limited, Huawei, Infinera, NEC and ZTE. These nine companies together in 2013 comprised approximately 84.5% of the digital optical communications equipment market, according to Infonetics.

Major suppliers of network equipment to the datacom market include Alcatel-Lucent, Brocade, Cisco, Huawei and Juniper. At the optical module and component level, Avago, Finisar and Sumitomo Device Innovations are leading suppliers. Some of the largest investors in datacenters, for example, Google, are beginning to design and source their own generic optical network equipment from Asia-based OEMs. While the speeds for most of the datacom market today are at 10G, a fast growing 100G module market is emerging that provides “big pipes” for datacenters.

A single optical fiber can carry nearly 100 individual wavelengths (colors), each of which can now support 100 gigabits per second of capacity. Each of these wavelengths requires a 100G transmitter and receiver, which can be tuned to any of the 100 separate channels. Thus, using 100G coherent technology and industry standard compression (MPEG-2), a single fiber can carry approximately 500,000 individual high definition full motion movies simultaneously over one fiber.

The main photonic modules required for digital optical communications are transmitters, receivers and, where the network is branched, optical switches. Transmitters and receivers are often combined into single modules which are called transceivers. At the high end, such as Long Haul, a transmitter and receiver can be paired and combined with signal processing electronics to error correct and restore degradation which affects the signal after traveling long distances, in which case the unit is referred to as a transponder. According to Infonetics, the market in 2014 for 100G coherent transponders, and for shorter distance client 100G transceivers, was approximately $600 million. For high speeds each of these product types requires photonic integration at the most advanced and complete level.

Switching products, which switch different colors, or signal channels, down different branches of the network, have thus far been Reconfigurable Optical Add/Drop Multiplexers (ROADMs) consisting of Wavelength Selective Switches (WSSs). For 100G coherent networks, a new type of optical switch, the Multi-Cast Switch (MCS), has been developed and introduced to eliminate contention in 100G coherent switching. This type of switch is Colorless, Directionless, Contentionless (CDC), and its function is optimized for 100G coherent networks.

Digital Optical Communications Technology Background

Advances in cost performance in photonic integration have followed a path that has been similar to electronic integrated circuits.

The main objectives for technology advances in electronic digital integrated circuits and in integrated optical digital devices are similar, and are based on the drive towards lower cost and higher performance. In integrated optics these main objectives also include higher speed, lower power, smaller or denser form factor, and lower cost.

In both electronics and optics these objectives require ever increasing integration and miniaturization. In optics, however, advanced hybrid integration is required for the highest performance products. Hybrid integration for digital optical devices incorporates multiple types of materials substrates, rather than just one, as in silicon, for an electronic integrated circuit.

Complete advanced photonics integration capability requires at least three materials substrate systems: Indium Phosphide for active devices such as lasers, photodiode detectors, modulators, and amplifiers; Silicon or planar doped silicon dioxide (silica) for wave guides, filters, interferometers and other passive devices; and Gallium Arsenide or Silicon Germanium for drivers and control functions at the speeds necessary for 100G. The integration of more than one material substrate is called hybrid integration, and Advanced Hybrid Photonic Integration enables products in the 100G and beyond domain.

Advent of Coherent Transmission

The recent advent of coherent digital optical transmission has increased the native capacity of a fiber optic link tenfold, versus a transmission modulation of simple on/off such as in 10G WDM networks. Coherent transmission modulation encodes information via phase and polarization, and the permutations of these variables are many times greater than on/off.

To create a detectable error-free signal in the coherent modality requires that each color (wavelength) transmitted be much purer than for lower speed protocols. The primary enabler of ultra-narrow line width (NLW), that is, ultra pure color, is a new generation of the most advanced lasers. These NLW lasers must be paired with a new generation of receivers that decode phase and polarization through comparison with another NLW laser in a PIC-interferometer. Ultra-narrow line width lasers are built on Indium Phosphide substrates while the receivers utilize a Silicon or Indium Phosphide interferometer and Indium Phosphide photo detectors.

These 100G coherent optical transmission devices require tighter tolerances of material thickness and other critical dimensions than do components operating at 10G. For 100G, a new generation of technologies, including faster Gallium Arsenide drivers, is required to suitably process transmission signals in both the laser transmitter or the detector and receiver. We believe we have well established and characterized the full range of laser and detector technologies required for implementing 100G coherent, a capability that we believe is held by only a few companies.

Our Advanced Hybrid Photonic Integration Platform

We believe we have developed or acquired all necessary capabilities required for producing high performance Advanced Hybrid Photonic Integrated optoelectronic devices for the most stringent performance requirements and operating conditions. Our multi-material platform leverages:

Indium Phosphide (InP): Indium Phosphide is used to produce efficient lasers, sensitive photo detectors and modulators in the wavelength window typically used for telecommunications, i.e. 1.55 micron wavelengths, as it is a direct bandgap III-V compound semiconductor material. InP is the most important material for the generation of laser signals and the detection and conversion of those signals back to electronic form.

Silicon (Silicon Photonics or Planar Lightwave Circuits): Silicon is a very inefficient in generating or detecting light in the telecom wavelength window as it is an indirect bandgap semiconductor material. Consequently, waveguides of Silicon or doped silicon dioxide (silica) exhibit very low optical loss and are ideal for switching, filtering or interferometric applications. Modulators using Silicon waveguides are now being developed.

Gallium Arsenide (GaAs): Gallium Arsenide can operate at very high speeds and is well suited to make analog integrated circuit drivers for high speed lasers and modulators due to its high electron mobility. GaAs is a direct bandgap III-V compound semiconductor material, but unlike InP, GaAs does not lase in the telecom wavelength window.

Silicon Germanium (SiGe): Silicon Germanium is an alloy of Silicon and Germanium that is used to manufacture mixed signal and analog integrated circuits and is well suited for high speed amplifiers used in 100G systems. SiGe devices are made using standard silicon processing techniques in commercial foundries.

We have developed design, integration and manufacturing approaches and techniques to produce advanced, high speed integrated solutions leveraging each of these in-house materials technology platforms.

Our Strategy

•

Continue innovating to develop industry-leading comprehensive technology for Advanced Hybrid Photonic Integration. Over the past three years, we have strengthened our technology platforms for comprehensive advanced photonic integration, in part from acquisitions and in part from internally funded development. We expect to continue to combine our mixed platform approach to design and produce the highest performance optical signal processing solutions.

•

Capture major customer share for the most advanced modules and components at the top suppliers of state of the art network equipment. We intend to deepen our relationships with our strategic customers by increasing design wins in their systems, including Alcatel-Lucent, Ciena and Huawei Technologies and certain others, which are market leaders in 100G coherent systems.

•

Offer a complete optoelectronic product line for 100G and beyond for leading edge telecom and datacom market segments. We expect to continue to introduce Coherent Transmitter products that are optimized for the highest speeds and introduce Multi-Cast Switches so that our product line will include each of the major types of the most advanced products.

•

Attain sustained profitability as a leading supplier of advanced optoelectronic products. We intend to provide state of the art products to industry leading customers to advance our goal of achieving continuous improvement in operating performance, profitability and growth.

•

Focus on high growth segments that leverage our leadership in Advanced Hybrid Photonic Integration and that contribute to our profitable growth. We plan to continue to develop our products and solutions to capture new opportunities, such as emerging 100G connections in both carrier networks and within and between large datacenters.

•

Extend our product line into additional segments of the network that will benefit from ultra-high speed performance. We intend to penetrate the emerging market for 100G connections both within and between mega-datacenters. In this segment we are targeting major users and builders of datacenters and datacenter equipment, such as Amazon, Apple, Facebook, Google and Microsoft, as they develop some of their own network equipment. We believe our technology and product line is well positioned to penetrate this market.

•

Pursue acquisitions that extend our leadership position in advanced optoelectronic integration. We may opportunistically pursue acquisitions that we believe provide complementary technology and that can accelerate our growth and strengthen our market position.

Our Technology

We have developed expertise in the design, large-scale fabrication, high-volume module manufacturing and commercial deployment of our Advanced Hybrid Photonic Integration products and technologies. The process of designing and manufacturing advanced optoelectronic integrated devices in high volume with predictable, well-characterized performance and low manufacturing costs is complex and multi-faceted. We have developed the technologies, using multiple materials platforms for photonic integration, that are required to design and manufacture complex, high-performance optoelectronic components, modules and subsystems for fiber optic networks. The basic elements of our technology are as follows:

Mixed-material platform and optoelectronic integration technology. We utilize a set of proprietary integration platforms that provide optoelectronic functionality on silicon and other integrated compound semiconductor substrates including Indium Phosphide, Gallium Arsenide and Silicon Germanium and integrated combinations of these platforms. We utilize micron and sub-micron scale structures of multiple silicon dioxide and Indium Phosphide waveguides to fabricate optoelectronic functional elements such as lasers, detectors, modulators, interferometers, integrated optical filters, switches and variable attenuators. We integrate these functional design elements into optoelectronic devices to achieve a desired functionality and specification that is incorporated into our products. Similarly, we use Gallium Arsenide and Silicon Germanium integration platforms for drivers, amplifiers and related high-speed electronic control functions for our integrated optoelectronic devices.

Advanced Hybrid Photonic Integration. Through precise fabrication and positioning of physical features, we can integrate numerous different optoelectronic devices, which are fabricated on separate wafers from different semiconductor and related materials, matching the material to the function to create improved performance by using the highest performance elements of each type. For example, our hybrid integration allows us to integrate active devices, such as photodiodes or lasers fabricated using Indium Phosphide, with high-performance passive devices, such as interferometers, switches, routers and filters, fabricated on silicon, and to mate electronic amplifiers made with Silicon Germanium or drivers made with Gallium Arsenide directly to optical elements made with Silicon or Indium Phosphide.

This ability to combine specific functional elements out of optimized materials not only allows for very compact and low power components, but also through the intimate coupling of different elements, makes possible completely new functions. An example of this multi-platform architecture is found in the coherent optical communications domain where we intimately couple a passive interferometer with separate quadrature components carrying information and with photo detectors to turn a high speed optical signal into data-rich electrical signals for processing.

Hardware and firmware integration. We also sell our products as modules and subsystems which contain electronic hardware and firmware controls that interface directly with our customers’ systems. We design the electronic hardware and develop the firmware for our optical products to meet customer specifications.

Fabrication and manufacturing processes. We have developed expertise in the technology domains relevant to high-volume fabrication and manufacturing of our optoelectronic integrated circuit products using wafer-scale processes and including the complex interaction of electro-optic, thermal-optic and mechanical micro-thermal features. Our complex manufacturing steps are analogous to many processes used in the semiconductor industry. Each integrated element is tested and characterized using our proprietary test equipment before incorporation into our products.

Circuit design and design-for-manufacturing tools. We use a comprehensive set of proprietary as well as industry standard software design tools, to model relevant geometries, dimensions and thermal management for a broad range of photonic devices. With these tools, we develop products with minimal design iterations and manage precision manufacturing to a narrow range of high performance specifications.

Our Products

We develop and manufacture Transmitter Products, Receiver Products and Switch Products that are used in ultra-high speed digital optical communications, high speed switching and provisioning, and access connections for wireless and fiber-to-the-home communications networks. We combine our transmitter and receiver products into Transceiver modules. Our Switching Products, such as Multi-Cast Switches, are used primarily in ROADM nodes that dynamically and efficiently allocate bandwidth to adjust for fast changing traffic patterns and for provisioning software defined networks. Our products can be categorized into groups, including high speed products for ultra high speed 100G and beyond applications, including in coherent networks, and network products and solutions, for lower speed networks including Access, 10G networks and other telecom products.

High Speed Products: We produce transmitter and receiver products as well as switching products for 100G optical transmission applications over distances of 2 to 2,000 kilometers. All of our high speed 100G and beyond products are based on our Advanced Hybrid Photonic Integration technology. This technology supports encoding 100 gigabits or more per second of information for transmitting over a single channel and decoding the information at the receiver.

For long distance transport of 100 to 2,000 kilometers, we design and manufacture optical components for coherent systems, which manipulate light to encode ten times or more the amount of information in the same wavelength channel than is possible with traditional methods. This manipulation can only be accomplished using advanced photonic integration to intimately couple functional elements together. Our Coherent Products include Narrow Linewidth Tunable transmit and local oscillator lasers (NLW-ITLA), which generate the ultra-pure wavelength, or color, necessary for coherent transmission, and Integrated Coherent Receivers (ICRs), which decode the phase and polarization encoded coherent signal. We are developing new generations of Coherent Transmitters which combine the NLW-ITLA with an Indium Phosphide-based coherent modulator, with Gallium Arsenide drivers for the modulator.

For distances under 100 kilometers, we produce Externally Modulated Lasers (EMLs), Gallium Arsenide drivers for the EMLs, and Indium Phosphide receivers. In addition, we integrate these individual PICs to offer complete 100G optoelectronic transceiver modules.

We provide a proprietary switching solution for 100G coherent systems such as our Multi-Cast Switch (MCS) product line, which efficiently allocates bandwidth and signal routing. The Multi-Cast Switch provides scalable contentionless operation to achieve the highest traffic management efficiency, optimizing traffic flows in 100G coherent systems. Our MCS uses our PLC photonic integration platform and consists of a complex array of switches, waveguides, taps, crossings and other functional elements manufactured on Silicon wafers using standard semiconductor processing equipment.

Network Products and Solutions: We design and manufacture a broad range of products for optical communications networks and a variety of other applications, where the networks operate at speeds less than 100G. Many of these products provide high-bandwidth connections to base station antennas for mobile devices and to people and machines over fixed and wireless networks. As consumer connectivity speeds have increased through the transitions from 2G to 3G to 4G/LTE, the bandwidths necessary to aggregate and connect wireless traffic into the backbone network, including Mobile Backhaul, have also increased. We offer 10G EML lasers, laser drivers, modulator drivers, photodiode receivers, as well as complete transceiver modules, SFP+ modules and bidirectional transceiver modules designed with the necessary bandwidth for connecting 4G/LTE wireless base station antennas. Similarly, for wired connections, we design and manufacture Optical Line Terminal (OLT) transceivers for Fiber to the Home and Business in PON networks up to 10G data rates.

For applications under 100G, we also design and produce Switch Products which are manufactured using our Silicon wafer based waveguide integration platform. These products include Drop Modules used in current ROADM nodes.

In addition to products for fiber optic communications, we also sell products for test and measurement, instrumentation, industrial and research applications.

Each of the repriced eligible options or eligible stock appreciation rights is subject to a new vesting schedule as follows: 50% of the shares subject to such repriced eligible option or eligible stock appreciation right shall vest and become exercisable on January 1, 2016, and the remaining 50% shall vest and become exercisable in 12 equal monthly installments on each monthly anniversary thereafter, in each case subject to continued service with us or our subsidiaries on each applicable vesting; provided, however, that alternative vesting applies to certain eligible options or eligible stock appreciation rights if the expiration date of such eligible options or eligible stock appreciation rights is after January 30, 2016, but on or before January 1, 2017, or if the expiration date of such eligible options or eligible stock appreciation rights is prior to January 30, 2016, as described in detail in the offer materials filed with the SEC.

Short-term Borrowing Arrangement

In November 2014, our subsidiary in China entered into a second short-term advance financing agreement, under one of its line of credit facilities, to borrow $5.0 million against export sales to us as its parent company. This financing agreement bears interest at 2.33% per annum and service fees at 1.00% per annum. Interest, service fees and the principal are due in May 2015.

Update on Planned Expansion in the Russian Federation

In April 2012, we entered into a rights agreement with Open Joint Stock Company “RUSNANO”, one of our principal stockholders. Under the rights agreement, we agreed to make a $30.0 million investment commitment (the “Investment Commitment”) toward our Russian operations. The Investment Commitment can be partially satisfied by cash and/or non-cash investment inside or outside of Russia and/or by way of non-cash asset transfers.

We are currently required to satisfy the Investment Commitment by March 31, 2015. We intend to meet the Investment Commitment by March 31, 2015 if we can obtain Rusnano’s approval of our proposed transfer of non-cash assets in a timely manner. If we fail to meet the Investment Commitment by the deadline, including

failure to meet the Investment Commitment because Rusnano does not approve the transfer of non-cash assets or for other reasons, we will be required to pay a $5.0 million penalty as the sole and exclusive remedy for damages and monetary relief available to Rusnano for failure to meet the Investment Commitment.

Separately, on December 18, 2014, we entered into a Commitment to file a Resale Registration Statement and Related Waiver of Registration Rights, whereby Rusnano waived its registration rights in connection with this offering, and we committed to file with the U.S. Securities and Exchange Commission a Resale Registration Statement covering the resale of all shares of the common stock held by Rusnano no later than 100 days following the pricing date of this offering; provided, however, that if the pricing date of this offering has not occurred by February 15, 2015, then we are obligated to file the Resale Registration Statement no later than April 15, 2015. Rusnano also waived its demand registration rights under the original rights agreement and has agreed to enter into a lock up agreement with us whereby it will agree not to sell any shares of our common stock, or engage in certain other transactions relating to our securities, for a period of 60 days from the filing date of the Resale Registration Statement.

We believe that the use of non-GAAP gross profit, non-GAAP total operating expense, non-GAAP (loss) income from operations, non-GAAP net (loss) income from continuing operations and adjusted earnings before interest, taxes, depreciation and amortization, or adjusted EBITDA, is helpful for investors in determining

whether to invest in our common stock. In computing our non-GAAP financial measures, we exclude certain adjustments included under U.S. GAAP. Non-GAAP gross profit excludes the amortization of purchased intangibles, stock-based compensation expense, depreciation of acquisition-related fixed asset step-up, amortization of acquisition-related inventory step-up, acquisition-related costs and restructuring charges. Non-GAAP total operating expenses excludes these same items except for the amortization of acquisition-related inventory step-up. Additionally, it excludes goodwill impairment charges, adjustment to fair value of contingent consideration, gain on sale of shares of unconsolidated investee, net of direct costs and escrow settlement gain. Non-GAAP (loss) income from operations excludes these same items and amortization of acquisition-related inventory step-up. Non-GAAP net (loss) income from continuing operations excludes income from discontinued operations, deemed dividend on beneficial conversion of Series X redeemable convertible preferred stock, accretion of redeemable convertible preferred stock and income tax effect of non-GAAP adjustments from net loss attributable to NeoPhotonics Corporation common stockholders, in addition to the same items excluded from the non-GAAP (loss) income from operations. Adjusted EBITDA excludes interest expense (income), net, provision for (benefit from) income taxes and depreciation expense, in addition to the same items excluded from non-GAAP net (loss) income from continuing operations.

We believe that excluding the above-mentioned adjustments helps investors compare our operating performance with our results in prior periods. We believe that it is appropriate to exclude these items as they are not necessarily indicative of ongoing operating performance and, therefore, limit comparability between periods and between us and similar companies. We believe adjusted EBITDA is useful to investors because it is frequently used by securities analysts, investors and other interested parties in the evaluation of companies in our industry. In addition, we believe that adjusted EBITDA is useful in evaluating our operating performance compared to that of other companies in our industry because the calculation of adjusted EBITDA generally eliminates the effects of financing and income taxes and the accounting effects of capital spending and acquisitions, which items may vary for different companies for reasons unrelated to overall operating performance. We use these non-GAAP financial measures to evaluate the operating performance of our business and aid in the period-to-period comparability. We also use the non-GAAP financial measures for planning and forecasting and measuring results against the forecast and in certain cases for bonus targets for certain of our employees. Using several measures to evaluate the business allows us and investors to (1) assess our relative performance against our competitors and (2) ultimately monitor our capacity to generate returns for our stockholders.

The non-GAAP financial measures above include the non-GAAP adjustments that are summarized in the “Reconciliation of GAAP to non-GAAP Financial Measures” that follows.

Reconciliation of GAAP to non-GAAP Financial Measures

The non-GAAP financial measures in this prospectus are not presented in accordance with, nor are they a substitute for, U.S. generally accepted accounting principles or GAAP. In addition, these measures may be different from non-GAAP measures used by other companies, limiting their usefulness for comparison purposes. The non-GAAP financial measures used in this prospectus should not be considered in isolation from measures of financial performance prepared in accordance with GAAP. Investors are cautioned that there are material limitations associated with the use of non-GAAP financial measures as an analytical tool. In particular, many of the adjustments to our GAAP financial measures reflect the exclusion of items that are recurring and will be reflected in our financial results for the foreseeable future.

The reconciliation between the GAAP and non-GAAP financial measures is as follows:

RISK FACTORS

An investment in our securities involves a high degree of risk. Before you make a decision to invest in our common stock, you should consider carefully the risks described in the section entitled “Risk Factors” contained in our quarterly report on Form 10-Q for the quarterly period ended September 30, 2014, as filed with the SEC on November 10, 2014, which is incorporated herein by reference in its entirety. If any of these risks actually occur, our business, operating results, prospects or financial condition could be materially and adversely affected. This could cause the trading price of our common stock to decline and you may lose part or all of your investment. Moreover, the risks described are not the only ones that we face. Additional risks not presently known to us or that we currently deem immaterial also may affect our business, operating results, prospects or financial condition.

You should also carefully consider the following risk factors related to this offering:

Our stock price may be volatile.

The market price of our common stock could be subject to wide fluctuations in response to, among other things, the risk factors described in this section of our prospectus, and other factors beyond our control, such as fluctuations in the valuation of companies perceived by investors to be comparable to us.

The stock markets have experienced 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, sovereign debt or liquidity issues, interest rate changes or international currency fluctuations, may negatively affect the market price of our common stock.

In the past, many companies that have experienced volatility in the market price of their stock have been subject to securities class action litigation. We may become 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.

The concentration of our capital stock ownership with our executive officers and directors and their affiliates will limit other stockholders’ ability to influence corporate matters.

As of September 30, 2014, our executive officers and directors, and entities that are affiliated with them, beneficially own an aggregate of approximately 35.4% of our outstanding common stock. This significant concentration of share ownership may adversely affect the trading price for our common stock because investors often perceive disadvantages in owning stock in companies with controlling stockholders. Also, as a result, these stockholders, acting together, will be able to control our management and affairs and matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions. Consequently, this concentration of ownership may have the effect of delaying or preventing a change in control, including a merger, consolidation or other business combination involving us, or discouraging a potential acquirer from making a tender offer or otherwise attempting to obtain control, even if such a change in control would benefit our other stockholders.

We currently do not intend to pay dividends on our common stock and, consequently, your only opportunity to achieve a return on your investment is if the price of our common stock appreciates.

We currently do not plan to declare dividends on shares of our common stock in the foreseeable future. In addition, the terms of our revolving credit and term loan agreement with Comerica Bank and East-West Bank restrict our ability to pay dividends. Consequently, your only opportunity to achieve a return on your investment

in our company will be if the market price of our common stock appreciates and you sell your shares at a profit. There is no guarantee that the price of our common stock that will prevail in the market after our public offering will ever exceed the price that you pay.

Because our public offering price is substantially higher than the as adjusted net tangible book value per share of our outstanding common stock, new investors will incur immediate and substantial dilution.

The public offering price is substantially higher than the as adjusted net tangible book value per share of our common stock based on the expected total value of our total assets, less our goodwill and other intangible assets, less our total liabilities immediately following this offering. Therefore, if you purchase shares of our common stock in this offering, you will experience immediate and substantial dilution of $ per share in the price you pay for our common stock as compared to the as adjusted net tangible book value as of September 30, 2014. To the extent outstanding options or warrants to purchase common stock are exercised, there will be further dilution. For a further description of the dilution that you will experience immediately after this offering, see the section titled “Dilution.”

Our management has broad discretion in the use of the net proceeds from this offering and may not use the net proceeds effectively.

Our management will have broad discretion in the application of the net proceeds of this offering. We cannot specify with certainty the uses to which we will apply the net proceeds we will receive from this offering. The failure by our management to apply these funds effectively could adversely affect our ability to continue to maintain and expand our business.

Our charter documents and Delaware law could prevent a takeover that stockholders consider favorable and could also reduce the market price of our stock.

Our amended and restated certificate of incorporation and our amended and restated bylaws contain provisions that could delay or prevent a change in control of our company. These provisions could also make it more difficult for stockholders to elect directors and take other corporate actions. These provisions include:

•

providing for a classified board of directors with staggered, three-year terms;

•

not providing for cumulative voting in the election of directors;

•

authorizing our board of directors to issue, without stockholder approval, preferred stock rights senior to those of common stock;

•

prohibiting stockholder action by written consent;

•

limiting the persons who may call special meetings of stockholders; and

•

requiring advance notification of stockholder nominations and proposals.

In addition, we have been governed by the provisions of Section 203 of the General Corporation Law of the State of Delaware since the completion of our initial public offering. These provisions may prohibit large stockholders, in particular those owning 15% or more of our outstanding common stock, from engaging in certain business combinations without approval of substantially all of our stockholders for a certain period of time.

These and other provisions in our amended and restated certificate of incorporation, in our amended and restated bylaws and under Delaware law could discourage potential takeover attempts, reduce the price that investors might be willing to pay for shares of our common stock in the future and result in the market price being lower than it would be without these provisions.

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus, including the information that we incorporate by reference, contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that involve substantial risks and uncertainties. All statements other than statements of historical facts contained in this prospectus, including statements regarding our future financial condition, business strategy and plans and objectives of management for future operations, are forward-looking statements. Forward-looking statements include statements that are not historical facts and can be identified by terms such as “anticipates,” “believes,” “could,” “seeks,” “estimates,” “expects,” “intends,” “may,” “plans,” “potential,” “predicts, “projects,” “should,” “will,” “would” or similar expressions and the negatives of those terms.

Forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements. Given these uncertainties, you should not place undue reliance on these forward-looking statements. Also, forward-looking statements represent our management’s beliefs and assumptions only as of the date of this prospectus. You should read this prospectus, including the information that we incorporate by reference, and the documents that we have filed as exhibits to the registration statement, of which this prospectus is a part, completely and with the understanding that our actual future results may be materially different from what we expect.

Important factors that could cause actual results to differ materially from our expectations are disclosed under “Risk Factors” and elsewhere in this prospectus and in the information that we incorporate by reference, including, without limitation, in conjunction with the forward-looking statements appearing elsewhere in this prospectus and in the information that we incorporate by reference.

Except as required by law, we assume no obligation to update these forward-looking statements, or to update the reasons actual results could differ materially from those anticipated in these forward-looking statements, even if new information becomes available in the future.

USE OF PROCEEDS

We estimate that the net proceeds from our sale of shares of common stock in this offering at an assumed public offering price of $ per share, the last reported sale price of our common stock on the New York Stock Exchange on , 2015, after deducting the underwriting discount and estimated offering expenses payable by us, will be approximately $ million, or $ million if the underwriters’ option to purchase additional shares is exercised in full.

We intend to use our net proceeds from this offering for working capital, to continue to expand our existing business and general corporate purposes. Accordingly, our management will have broad discretion in the application of our net proceeds from this offering, and investors will be relying on management’s judgment regarding the application of these net proceeds. In connection with the planned closing of our acquisition of EMCORE’s tunable laser and transceiver product lines in January 2015, we will issue a promissory note in the amount of approximately $16 million; such promissory note will have a two-year term and will bear interest of 5% per annum for the first year and 13% per annum for the second year. If the amount of gross proceeds received in this offering is at least $15 million, we are required to prepay the principal of the note in an amount equal to $5.5 million. We also may use a portion of our net proceeds from this offering to acquire other complementary businesses, products, services or technologies, although we currently have no agreements or commitments relating to any material acquisitions. We may also use a portion of our net proceeds to repay a portion of our other outstanding indebtedness, but we currently have no commitments or specific plans to repay any particular indebtedness in advance of its maturity date. As of September 30, 2014, our outstanding short-term loans and long-term debt totaled $46.3 million with interest rates ranging from 1.50% to 7.00% and maturity dates ranging from October 2014 through June 2017. The repayment of our outstanding indebtedness may depend on the availability of future credit and the returns of alternative uses of the net proceeds compared to the interest rate charged by our lenders.

We also may use a portion of our net proceeds from this offering to pay the $5.0 million penalty to Rusnano if we do not meet the Investment Commitment.

Pending their use, we plan to invest the net proceeds to us from this offering in short term, interest bearing obligations, investment grade instruments, certificates of deposit or direct or guaranteed obligations of the U.S. government.

DIVIDEND POLICY

To date, no dividends have been declared, accrued, paid or otherwise earned on our common stock or preferred stock and we do not expect to pay dividends on our common stock or preferred stock in the foreseeable future. Instead, we anticipate that all of our earnings in the foreseeable future will be used for the operation and growth of our business. Any future determination to pay dividends on our common stock or preferred stock would be subject to the discretion of our board of directors and would depend upon various factors, including our results of operations, financial condition, liquidity requirements, restrictions that may be imposed by applicable law and our contracts and other factors deemed relevant by our board of directors. In addition, our revolving credit and term loan agreement with Comerica Bank and East-West Bank limits our ability to pay dividends.

stock options to purchase 3,735,404 shares of common stock with a weighted average exercise price of $5.94 per share;

•

667,525 shares of common stock issuable upon the vesting of restricted stock units;

•

DILUTION

Our net tangible book value as of September 30, 2014, was approximately $147.6 million, or $4.54 per share. Net tangible book value per share is determined by dividing our total tangible assets, less total liabilities, by the number of shares of our common stock outstanding as of September 30, 2014. Dilution with respect to net tangible book value per share represents the difference between the amount per share paid by purchasers of shares of common stock in this offering and the net tangible book value per share of our common stock immediately after this offering.

After giving effect to the sale of shares of our common stock in this offering, assuming a public offering price of $ per share, the last reported sale price of our common stock on the New York Stock Exchange on , 2015, and after deducting the underwriting discount and estimated offering expenses payable by us, our as adjusted net tangible book value as of September 30, 2014, would have been approximately $ million, or $ per share. This represents an immediate increase in net tangible book value of $ per share to existing stockholders and immediate dilution of $ per share to investors purchasing our common stock in this offering. The following table illustrates this dilution on a per share basis:


Assumed public offering price per share			$
Net tangible book value per share as of September 30, 2014, before giving effect to this offering	$	4.54
Increase in net tangible book value per share attributable to investors purchasing shares in this offering

As adjusted net tangible book value per share after this offering

Dilution per share to investors in this offering			$

Each $0.10 increase or decrease in the assumed public offering price of $ per share, the last reported sale price of our common stock on the New York Stock Exchange on , 2015, would increase or decrease, respectively, the as adjusted net tangible book value per share after this offering by approximately $ per share and the dilution per share to investors in this offering by approximately $ per share, assuming the offer and sale by us of shares by us and after deducting the underwriting discount and estimated offering expenses payable by us.

The foregoing discussion and table do not take into account further dilution to investors that could occur upon the exercise of the underwriters’ option to purchase up to an additional shares of our common stock within 30 days of the date of this prospectus. If the underwriters exercise in full their option to purchase additional shares of our common stock, assuming a public offering price of $ per share, the last reported sale price of our common stock on the New York Stock Exchange on , 2015, our net tangible book value on September 30, 2014, after giving effect to this offering, would have been approximately $ million, or approximately $ per share, representing an immediate dilution of $ per share to investors purchasing shares of common stock in this offering.

The above discussion and table do not take into account further dilution to investors purchasing our common stock in this offering that could occur upon the exercise of outstanding options and warrants having a per share exercise price less than the public offering price per share in this offering, or the vesting of outstanding restricted stock units. To the extent that outstanding options or warrants outstanding as of September 30, 2014, are exercised, restricted stock unit awards vest or other shares are issued, investors purchasing our common stock in this offering will experience further dilution. In addition, we may choose to raise additional capital due to market conditions or strategic considerations even if we believe that we have sufficient funds for our current or future operating plans. To the extent that additional capital is raised through the sale of our common stock, including through the sale of securities convertible into or exchangeable or exercisable for common stock, the

issuance of these securities could result in further dilution to our stockholders, including investors purchasing our common stock in this offering.

The foregoing dilution calculations exclude as of September 30, 2014:

•

stock options to purchase 3,735,404 shares of common stock with a weighted average exercise price of $5.94 per share;

•

667,525 shares of common stock issuable upon the vesting of restricted stock units;

•

345,489 shares of common stock reserved for future issuance under our 2011 equity inducement plan; and

•

warrants to purchase 4,482 shares of our common stock with an exercise price of $29.00 per share.

MATERIAL U.S. FEDERAL INCOME AND ESTATE TAX CONSEQUENCES

TO NON-U.S. HOLDERS

The following summary describes the material U.S. federal income and estate tax consequences of the acquisition, ownership and disposition of our common stock acquired in this offering by Non-U.S. Holders (as defined below). This discussion does not address all aspects of U.S. federal income and estate taxes and does not deal with foreign, state and local consequences that may be relevant to Non-U.S. Holders in light of their particular circumstances, nor does it address U.S. federal tax consequences other than income and estate taxes. Special rules different from those described below may apply to certain Non-U.S. Holders that are subject to special treatment under the Internal Revenue Code of 1986, as amended, or the Code, such as financial institutions, insurance companies, tax-exempt organizations, broker-dealers and traders in securities, U.S. expatriates, “controlled foreign corporations,” “passive foreign investment companies,” corporations that accumulate earnings to avoid U.S. federal income tax, persons that hold our common stock as part of a “straddle,” “hedge,” “conversion transaction,” “synthetic security” or integrated investment or other risk reduction strategy, persons subject to the alternative minimum tax or Medicare contribution tax, partnerships and other pass-through entities, and investors in such pass-through entities. Such Non-U.S. Holders are urged to consult their own tax advisors to determine the U.S. federal, state, local and other tax consequences that may be relevant to them. Furthermore, the discussion below is based upon the provisions of the Code, and Treasury regulations, rulings and judicial decisions thereunder as of the date hereof, and such authorities may be repealed, revoked or modified, perhaps retroactively, so as to result in U.S. federal income and estate tax consequences different from those discussed below. We have not requested a ruling from the U.S. Internal Revenue Service, or IRS, with respect to the statements made and the conclusions reached in the following summary, and there can be no assurance that the IRS will agree with such statements and conclusions. This discussion assumes that the Non-U.S. Holder holds our common stock as a “capital asset” within the meaning of Section 1221 of the Code (generally, property held for investment).

Persons considering the purchase of our common stock pursuant to this offering should consult their own tax advisors concerning the U.S. federal income and estate tax consequences of the acquisition, ownership and disposition of our common stock in light of their particular situations as well as any consequences arising under the laws of any other taxing jurisdiction, including any state, local or foreign tax consequences.

For the purposes of this discussion, a “Non-U.S. Holder” is, for U.S. federal income tax purposes, a beneficial owner of common stock that is neither a U.S. Holder, nor a partnership (or other entity treated as a partnership for U.S. federal income tax purposes regardless of its place of organization or formation). A “U.S. Holder” means a beneficial owner of our common stock that is for U.S. federal income tax purposes (a) an individual who is a citizen or resident of the United States, (b) a corporation or other entity treated as a corporation created or organized in or under the laws of the United States, any state thereof or the District of Columbia, (c) an estate the income of which is subject to U.S. federal income taxation regardless of its source or (d) a trust if it (1) is subject to the primary supervision of a court within the United States and one or more U.S. persons have the authority to control all substantial decisions of the trust or (2) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

Distributions

Subject to the discussion below, distributions, if any, made on our common stock to a Non-U.S. Holder of our common stock to the extent made out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles) generally will constitute dividends for U.S. tax purposes and will be subject to withholding tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty. To obtain a reduced rate of withholding under a treaty, a Non-U.S. Holder generally will be required to provide us or our paying agent with a properly executed IRS Form W-8BEN (in the case of an individual), IRS Form W-8BEN-E (in the case of an entity), or other appropriate form, certifying the Non-U.S. Holder’s entitlement to benefits under that treaty. In the case of a Non-U.S. Holder that is an entity, Treasury Regulations

and the relevant tax treaty provide rules to determine whether, for purposes of determining the applicability of a tax treaty, dividends will be treated as paid to the entity or to those holding an interest in that entity. If a Non-U.S. Holder holds stock through a financial institution or other agent acting on the holder’s behalf, the holder will be required to provide appropriate documentation to such agent. The holder’s agent will then be required to provide certification to us or our paying agent, either directly or through other intermediaries. If you are eligible for a reduced rate of U.S. federal withholding tax under an income tax treaty, you may be able to obtain a refund or credit of any excess amounts withheld by timely filing an appropriate claim for a refund with the IRS.

We generally are not required to withhold tax on dividends paid to a Non-U.S. Holder that are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, are attributable to a permanent establishment that such holder maintains in the United States) if a properly executed IRS Form W-8ECI, stating that the dividends are so connected, is furnished to us or our paying agent (or, if stock is held through a financial institution or other agent, to such agent). In general, such effectively connected dividends will be subject to U.S. federal income tax, on a net income basis at the regular graduated rates. A corporate Non-U.S. Holder receiving effectively connected dividends may also be subject to a “branch profits tax,” which is imposed, under certain circumstances, at a rate of 30% (or such lower rate as may be specified by an applicable treaty) on the corporate Non-U.S. Holder’s effectively connected earnings and profits, subject to certain adjustments. To the extent distributions on our common stock, if any, exceed our current and accumulated earnings and profits, they will first reduce the Non-U.S. Holder’s adjusted basis in our common stock, but not below zero, and then will be treated as gain to the extent of any excess, and taxed in the same manner as gain realized from a sale or other disposition of common stock as described in the next section.

Non-U.S. Holders may be required to periodically update their IRS Form W-8.

Gain on Disposition of our Common Stock

Subject to the discussion below regarding backup withholding and foreign accounts, a Non-U.S. Holder generally will not be subject to U.S. federal income tax with respect to gain realized on a sale or other disposition of our common stock unless (a) the gain is effectively connected with a trade or business of such holder in the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment that such holder maintains in the United States), (b) the Non-U.S. Holder is a nonresident alien individual and is present in the U.S. for 183 or more days in the taxable year of the disposition and certain other conditions are met or (c) we are or have been a “U.S. real property holding corporation” within the meaning of Code Section 897(c)(2) at any time within the shorter of the five-year period preceding such disposition or such holder’s holding period. In general, we would be a U.S. real property holding corporation if interests in U.S. real estate comprised (by fair market value) at least half of our business assets. We believe that we are not, and do not anticipate becoming, a U.S. real property holding corporation. Even if we are treated as a U.S. real property holding corporation, gain realized by a Non-U.S. Holder on a disposition of our common stock will not be subject to U.S. federal income tax so long as (1) the Non-U.S. Holder owned, directly, indirectly and constructively, no more than five percent of our common stock at all times within the shorter of (i) the five-year period preceding the disposition or (ii) the holder’s holding period and (2) our common stock is regularly traded on an established securities market. There can be no assurance that our common stock will qualify or will continue to qualify as regularly traded on an established securities market.

If you are a Non-U.S. Holder described in (a) above, you will be required to pay tax on the net gain derived from the sale at regular graduated U.S. federal income tax rates, and corporate Non-U.S. Holders described in (a) above may also be subject to the a branch profits tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty. If you are an individual Non-U.S. Holder described in (b) above, you will be required to pay a flat 30% tax on the gain derived from the sale, which gain may be offset by U.S. source capital losses (even though you are not considered a resident of the United States).

Information Reporting Requirements and Backup Withholding

Generally, we must report information to the IRS with respect to any distributions we make on our common stock (whether or not the distribution represents taxable dividend income) including the amount of any dividends, the name and address of the recipient, and the amount, of any tax withheld. A similar report is sent to the holder to whom any such dividends are paid. Pursuant to tax treaties or certain other agreements, the IRS may make its reports available to tax authorities in the recipient’s country of residence.

Dividends paid by us (or our paying agents) to a Non-U.S. Holder may also be subject to U.S. backup withholding. U.S. backup withholding generally will not apply to a Non-U.S. Holder who provides a properly executed IRS Form W-8BEN or IRS Form W-8BEN-E or otherwise establishes an exemption.

Under current U.S. federal income tax law, U.S. information reporting and backup withholding requirements generally will apply to the proceeds of a disposition of our common stock effected by or through a U.S. office of any broker, U.S. or foreign, except that information reporting and such requirements may be avoided if the holder provides a properly executed IRS Form W-8BEN or IRS Form W-8BEN-E or otherwise meets documentary evidence requirements for establishing Non-U.S. Holder status or otherwise establishes an exemption. Generally, U.S. information reporting and backup withholding requirements will not apply to a payment of disposition proceeds to a Non-U.S. Holder where the transaction is effected outside the United States through a non-U.S. office of a non-U.S. broker provided, however, that no office of the same broker within the U.S. negotiated the sale or received instructions with respect to the sale from the payee. Information reporting and backup withholding requirements may, however, apply to a payment of disposition proceeds if the broker has actual knowledge, or reason to know, that the holder is, in fact, a U.S. person. For information reporting purposes, certain brokers with substantial U.S. ownership or operations will generally be treated in a manner similar to U.S. brokers.

Any amounts of tax withheld under the backup withholding rules may be credited against the tax liability of persons subject to backup withholding, provided that the required information is timely furnished to the IRS.

Foreign Accounts

A U.S. federal withholding tax of 30% may apply on dividends on and the gross proceeds of a disposition of our common stock paid to a foreign financial institution (as specifically defined by applicable rules) unless such institution enters into an agreement with the U.S. government to withhold on certain payments and to collect and provide to the U.S. tax authorities substantial information regarding U.S. account holders of such institution (which includes certain equity holders of such institution, as well as certain account holders that are foreign entities with U.S. owners). This U.S. federal withholding tax of 30% will also apply on dividends on and the gross proceeds of a disposition of our common stock paid to a non-financial foreign entity unless such entity provides the withholding agent with either a certification that it does not have any substantial direct or indirect U.S. owners or provides information regarding substantial direct and indirect U.S. owners of the entity. The withholding tax described above will not apply if the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from the rules. Under certain circumstances, a Non-U.S. Holder might be eligible for refunds or credits of such taxes. An intergovernmental agreement between the United States and an applicable foreign country may modify the requirements described in this paragraph. Holders are encouraged to consult with their own tax advisors regarding the possible implications of these rules for their investment in our common stock.

The withholding provisions described above will generally apply to payments of dividends made on or after July 1, 2014 and to payments of gross proceeds from a sale or other disposition of common stock on or after January 1, 2017.

Federal Estate Tax

An individual who is not a citizen of the United States and is also a nonresident (as specially defined for estate tax purposes) who is treated as the owner of, or has made certain lifetime transfers of, an interest in our common stock will be required to include the value thereof in his or her gross estate for U.S. federal estate tax purposes, and may be subject to U.S. federal estate tax unless an applicable estate tax treaty provides otherwise, even though such individual was not a citizen or resident of the United States at the time of his or her death.

EACH PROSPECTIVE INVESTOR SHOULD CONSULT ITS OWN TAX ADVISOR REGARDING THE TAX CONSEQUENCES OF THE ACQUISITION, OWNERSHIP AND DISPOSITION OF OUR COMMON STOCK, INCLUDING THE CONSEQUENCES OF ANY PROPOSED CHANGE IN APPLICABLE LAW.

UNDERWRITING

We have entered into an underwriting agreement with the underwriters named below. Needham & Company, LLC is acting as representative of the underwriters. The underwriters’ obligations are several, which means that each underwriter is required to purchase a specific number of shares, but is not responsible for the commitment of any other underwriter to purchase shares. Subject to the terms and conditions of the underwriting agreement, each underwriter has severally agreed to purchase from us the number of shares of common stock set forth opposite its name below.


Underwriter		Number of Shares
Needham & Company, LLC
Craig-Hallum Capital Group LLC

Total

The underwriting agreement provides that the underwriters are obligated to purchase all the shares of common stock in the offering if any are purchased, other than those shares covered by the over-allotment option described below.

The underwriting agreement provides that we will indemnify the underwriters against certain liabilities that may be incurred in connection with this offering, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”), or to contribute payments that the underwriters may be required to make in respect thereof.

We have granted an option to the underwriters to purchase up to additional shares of common stock at the public offering price per share, less the underwriting discount, set forth on the cover page of this prospectus. This option is exercisable during the 30-day period after the date of this prospectus. The underwriters may exercise this option only to cover over-allotments made in connection with this offering. If this option is exercised, each of the underwriters will purchase approximately the same percentage of the additional shares as the number of shares of common stock to be purchased by that underwriter, as shown in the table above, bears to the total shown.

The representative has advised us that the underwriters propose to offer the shares of common stock to the public at the public offering price per share set forth on the cover page of this prospectus. The underwriters may offer shares to securities dealers, who may include the underwriters, at that public offering price less a concession of up to $ per share. After the offering to the public, the offering price and other selling terms may be changed by the representative.

The following table shows the per share and total underwriting discount to be paid to the underwriters by us. These amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase additional shares.

No Exercise

Paid by us

We estimate that the total expenses of the offering, excluding the underwriting discount, will be approximately $ . We have also agreed to reimburse the underwriters for up to $ of fees and expenses incurred by them in connection with this offering.

We have agreed not to offer, sell, contract to sell, pledge, grant options to purchase, or otherwise dispose of any shares of our common stock or securities exchangeable for or convertible into our common stock for a period

of 90 days after the date of this prospectus without the prior written consent of Needham & Company, LLC. This agreement does not apply to any existing employee benefit plans. Our directors, officers and other stockholders, who collectively hold in the aggregate shares of common stock, have agreed, subject to certain exceptions, not to, directly or indirectly, sell, hedge, or otherwise dispose of any shares of common stock, options to acquire shares of common stock or securities exchangeable for or convertible into shares of common stock, for a period of 90 days after the date of this prospectus without the prior written consent of Needham & Company, LLC. However, in the event that either (1) during the last 17 days of the “lock-up” period, we release earnings results or material news or a material event relating to us occurs or (2) prior to the expiration of the “lock-up” period, we announce that we will release earnings results during the 16-day period beginning on the last day of the “lock-up” period, then in either case the expiration of the “lock-up” will be extended until the expiration of the 18-day period beginning on the date of the release of the earnings results or the occurrence of the material news or event, as applicable, unless Needham & Company, LLC waives, in writing, such an extension. A transfer of securities to a family member, trust, affiliate, partner or member of such person, or as a bona fide gift, may be made, provided the transferee agrees to be bound in writing by the above restrictions prior to the transfer.

In connection with this offering, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of our common stock. Specifically, the underwriters may over-allot in connection with this offering by selling more shares than are set forth on the cover page of this prospectus. This creates a short position in our common stock for their own account. The short position may be either a covered short position or a naked short position. In a covered short position, the number of shares over-allotted by the underwriters is not greater than the number of shares that they may purchase in the over-allotment option. In a naked short position, the number of shares involved is greater than the number of shares in the over-allotment option. To close out a short position or to stabilize the price of our common stock, the underwriters may bid for, and purchase, common stock in the open market. The underwriters may also elect to reduce any short position by exercising all or part of the over-allotment option. In determining the source of shares to close out the short position, the underwriters will consider, among other things, the price of shares available for purchase in the open market as compared to the price at which they may purchase shares through the over-allotment option. If the underwriters sell more shares than could be covered by the over-allotment option, a naked short position, the position can only be closed out by buying shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there could be downward pressure on the price of the shares in the open market after pricing that could adversely affect investors who purchase in the offering.

The underwriters may also impose a penalty bid. This occurs when a particular underwriter or dealer repays selling concessions allowed to it for distributing our common stock in this offering because the underwriters repurchase that stock in stabilizing or short covering transactions.

These activities may stabilize or maintain the market price of our common stock at a price that is higher than the price that might otherwise exist in the absence of these activities. The underwriters are not required to engage in these activities, and may discontinue any of these activities at any time without notice. These transactions may be effected on the New York Stock Exchange, in the over-the-counter market, or otherwise.

LEGAL MATTERS

The validity of the shares of common stock offered hereby will be passed upon for us by Cooley LLP, Palo Alto, California. Pillsbury Winthrop Shaw Pittman LLP, San Francisco, California, is acting as counsel for the underwriters in connection with certain legal matters relating to the shares of common stock offered by this prospectus.

Item 14. Indemnification of Directors and Officers.

We are incorporated under the General Corporation Law of the State of Delaware (the “Delaware General Corporation Law”). Section 145 of the Delaware General Corporation Law authorizes a court to award, or a corporation’s board of directors to grant, indemnity to directors and officers under certain circumstances and subject to certain limitations. The terms of Section 145 of the Delaware General Corporation Law are sufficiently broad to permit indemnification under certain circumstances for liabilities, including reimbursement of expenses incurred, arising under the Securities Act.

As permitted by the Delaware General Corporation Law, our certificate of incorporation includes a provision that eliminates, to the fullest extent permitted by law, the personal liability of a director for monetary damages resulting from breach of his fiduciary duty as a director.

As permitted by the Delaware General Corporation Law, our bylaws provide that:

•

we are required to indemnify our directors and officers to the fullest extent permitted by the Delaware General Corporation Law;

•

we may indemnify our other employees and agents as provided in indemnification contracts entered into between us and our employees and agents;

•

we are required to advance expenses, as incurred, to our directors and officers in connection with a legal proceeding to the fullest extent permitted by the Delaware General Corporation Law; and

•

the rights conferred in the bylaws are not exclusive.

Our policy is to enter into separate indemnification agreements with each of our directors and officers that provide the maximum indemnity allowed to directors and executive officers by Section 145 of the Delaware General Corporation Law and also provide for certain additional procedural protections. We currently carry liability insurance for our directors and officers. At present, there is no pending litigation or proceeding involving one of our directors or officers regarding which indemnification is sought, nor are we aware of any threatened litigation that may result in claims for indemnification.

II-1

These indemnification provisions and the indemnification agreements entered into between us and our officers and directors may be sufficiently broad to permit indemnification of our officers and directors for liabilities (including reimbursement of expenses incurred) arising under the Securities Act.

The Underwriting Agreement filed as Exhibit 1.1 to this Registration Statement provides for indemnification by the underwriters of us and our directors and officers for certain liabilities under the Securities Act, or otherwise.

Item 15. Recent Sales of Unregistered Securities.

On April 27, 2012, the registrant entered into a share purchase agreement (the “Purchase Agreement”) with Open Joint Stock Company “RUSNANO”, an entity organized under the laws of the Russian Federation (“Rusnano”), pursuant to which the registrant agreed to sell and issue an aggregate of 4,972,905 shares of common stock at a purchase price of $8.00 per share for aggregate gross proceeds of approximately $39.8 million (the “Private Placement”). The closing of the Private Placement occurred on April 27, 2012. Immediately after the closing of the Private Placement, Rusnano owned approximately 16.7% of the issued and outstanding common stock of the registrant. The Purchase Agreement included representations, warranties and covenants customary for a transaction of this type. No underwriting discounts or commissions were paid in this transaction.

The securities sold were not registered under the Securities Act of 1933, as amended (the “Securities Act”), and may not be offered or sold in the United States without registration or an applicable exemption from the registration requirements of the Securities Act. The issuance was made in reliance on Rule 506 promulgated under the Securities Act and was made without general solicitation or advertising. Rusnano represented that it is an accredited investor with access to information about the registrant sufficient to evaluate the investment and that the securities were being acquired without a view to distribution or resale in violation of the Securities Act. A Form D filing was made in accordance with the requirements of Regulation D.

Item 16. Exhibits and Financial Statement Schedules.

(a) Exhibits.

The exhibits to the registration statement are listed in the Exhibit Index attached hereto and incorporated by reference herein.

(b) Financial Statement Schedules.

Financial statement schedules have been omitted, as the information required to be set forth therein is included in the Consolidated Financial Statements or Notes thereto incorporated by reference into the prospectus made part of this registration statement.

Item 17. Undertakings.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

II-2

The undersigned registrant hereby undertakes that:

(1)

For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(2)

For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

II-3

Pursuant to the requirements of the Securities Act of 1933, the registrant has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of San Jose, State of California, on the 19th day of December, 2014.
