BUSINESS

Overview

We are a leading designer and manufacturer of photonic integrated circuit, or PIC, -based modules and subsystems for bandwidth-intensive,
high-speed communications networks.

Our products are designed to enable cost-effective, high-speed data transmission and
efficient allocation of bandwidth over communications networks. We have a portfolio of over 300 products, including products that enable data transmission at 10 gigabits per second, or Gbps, 40Gbps and 100Gbps, agility products such as ROADMs, or
reconfigurable add/drop multiplexers, that dynamically allocate bandwidth to adjust for traffic patterns, and access products that provide high-bandwidth connections to more devices and people over fixed and wireless networks.

Our PIC technology utilizes proprietary design elements that provide optical functionality on a silicon chip. PIC devices can integrate
many more functional elements than discretely packaged components, enabling increased functionality in a small form factor while reducing packaging and interconnection costs. In addition, the cost advantages of PIC-based components are similar to
the economics of semiconductor wafer mass manufacturing, where the marginal cost of producing an incremental chip is much less than that of a discrete component.

We have research and development and wafer fabrication facilities in San Jose, California which coordinate with our research and development and manufacturing facilities in Shenzhen, China. We utilize
proprietary design tools and design-for-manufacturing techniques to align our design process with our precision nanoscale, vertically integrated manufacturing and testing capabilities. We sell our products to the leading network equipment vendors
globally, including ADVA AG Optical Networking Ltd., Alcatel-Lucent SA, Ciena

Technology

We have developed expertise in the design, large-scale fabrication, high-volume module manufacturing and commercial deployment of our PIC products and technologies. The process of designing and
manufacturing PICs in high volume with predictable, well-characterized performance and low manufacturing costs is complex and multi-faceted. We believe we have been able to develop the technologies that address and solve a range of interrelated
problems that enable the efficient design and manufacture of complex, high-performance components, modules and subsystems for fiber optic networks. The basic elements of our technology are as follows:

Photonic integrated circuits (PICs).We have developed a set of proprietary design elements that provide optical functionality on a
silicon chip. We utilize micron and sub-micron scale structures of multiple precision-doped silica planar waveguides to fabricate functional elements such as integrated optical filters, switches and

variable attenuators. By increasing the level of material doping in our planar waveguides, we decrease the size of our functional elements, thereby creating a path for larger scale integration of
multiple elements in the same chip area. We integrate these functional design elements into optical circuits to achieve a desired functionality and specification that is incorporated in our products.

Hybrid PIC integration.Through precise fabrication and positioning of physical features, we can integrate PIC devices fabricated
on separate wafers out of different materials, matching the material to the function to improve performance attributes and reduce production costs. Our hybrid integration allows us to integrate active devices, such as photodiodes, with
high-performance passive devices, such as switches, routers and filters, to provide the desired network functions on a single PIC.

Hardware and firmware integration. We also sell our products as modules and subsystems which contain electronic hardware and firmware control that can be interfaced directly with customer systems.
We design the electronic hardware and develop the firmware to integrate these with 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 PIC products with wafer-scale processes,
including the complex interaction of electro-optic, thermal-optic and mechanical micro-thermal features. We have developed and characterized our complex manufacturing steps, which are analogous to those used in the semiconductor industry. Each PIC
element is tested and characterized using our proprietary equipment before incorporation into our products.

Circuit design
and design-for-manufacturing tools.We utilize a comprehensive set of proprietary as well as industry standard software design tools, which permit us to model relevant geometries, dimensions and thermal management for a broad range of photonic
devices, which then allows us to develop products with minimal design iterations and to manufacture to a range of specifications.

Products

We have a broad portfolio of over 300 products, including high-speed products that enable data transmission at 10Gbps,
40Gbps and 100Gbps, agility products such as ROADMs that dynamically allocate bandwidth to adjust for volatile traffic patterns, and access products that provide high-bandwidth connections to more devices and people over fixed and wireless networks.
As of December 31, 2010, we categorized our products into 35 product families.

Speed

Speed refers to the ability to transmit data at high data rates. A key limitation of network capacity is the amount of data that can be
transmitted through a single fiber from one point to another. To address this limitation, we have a portfolio of products enabling data transmission at speeds of 2.5Gbps, 10Gbps, 40Gbps and 100Gbps, shown below.

manufacturing teams. Our sales and marketing organizations support our strategy of increasing product penetration with our Tier 1 customers while also serving our broader customer base. 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. The length of our sales cycle, from initial request to design win, is typically 6 to 12 months for an existing product and 18 months or longer
for a new product.

Our sales process involves collaboration and regular discussion with our customers early in their design
cycles to implement new product development programs. Our sales organization facilitates these activities by working with our product engineering managers and design teams to conduct periodic engineering reviews and program reviews with
counterparts at our customers. We believe that these collaborative engineering activities provide us insight into our customers broader and longer term needs.

We use a direct sales force based in the United States, China, Canada, Israel, Japan, Russia and the European Union. These individuals work with our product engineers, and product marketing and sales
operations teams, in an integrated approach to address our customers current and future needs. We believe we are well positioned to capitalize on the migration of our customers operations to China, where our Shenzhen-based sales and
engineering staff is able to support our customers. We also engage independent commissioned representatives and distributors to extend our global reach. We expect to continue to add sales and related support personnel as we grow our
business.

Our marketing team focuses on product strategy, product development, roadmap development, new product introduction
processes, program management, product demand stimulation and assessment, and competitive analysis. Our marketing team also seeks to educate the market about our products by communicating the value proposition and product differentiation in direct
customer interactions and presentations and at industry tradeshows and at technical conferences.

Research and development

We have new product development and product sustaining engineering teams in San Jose, California and Shenzhen, China. In our San Jose
facilities, we conduct PIC research, development and product roadmap

definitions. In our Shenzhen facilities, we conduct new product development, manufacturing and process engineering, quality control and continuous improvement and cost reduction relating to
product manufacturing, assembly and test. We have invested and expect to continue to invest significant time and capital into our research and development operations. Research and development expenses were $21.5 million, $17.3 million and $21.5
million in 2010, 2009 and 2008, respectively.

Intellectual property

Our success as a company depends in part upon our ability to obtain and maintain proprietary protections for our technology and
intellectual property and prevent others from infringing these proprietary rights. To accomplish this objective, we rely on a combination of intellectual property rights, including patent, trademark, copyright, trade secret, and unfair competition
laws, as well as license agreements and other contractual protections.

We have filed applications for patents to protect
certain of our intellectual property in the United States and in other countries, including Australia, Japan, Korea, China, Taiwan and certain countries in the European Union. Our patents will expire between 2013 and 2028.

Because our U.S. patents do not afford any intellectual property protection in China, where we have substantial operations, we also seek
to secure, to the extent possible, intellectual property protections in China. While we have issued patents and pending patent applications in China, portions of our intellectual property portfolio are not yet protected by patents in China.
Moreover, the level of protection afforded by patent and other laws in China may not be comparable to that afforded in the United States. See Risk factorsRisks related to our businessIf we fail to protect, or incur significant
costs in defending, our intellectual property and other proprietary rights, our business and results of operation could be materially harmed.

Our portfolio of patents and patent applications covers a range of intellectual property, including without limitation PIC fabrication and design, hybrid PIC integration, large scale integration for
optical circuit designs, and methods and apparatus for assembly and packaging.

We seek to protect our intellectual property
rights by having our employees and independent consultants enter into a confidentiality and inventions assignment agreements when they join us. Additionally, we enter into non-disclosure agreements with other third parties who may have access to our
proprietary technologies and information.

In addition, we have registered the trademark NeoPhotonics in the
United States.

Manufacturing, assembly and test

We have manufacturing operations in the United States and China. Our wafer fabrication operations are located in our San Jose, California facilities and include chip design, clean room fabrication,
integration and related facilities for PICs. Our manufacturing, assembly and test operations are located in our Shenzhen, China facilities, and include clean room fabrication, general manufacturing and assembly and test operations utilizing
production expertise and cost-effective volume capabilities. Our operations in Shenzhen have primary responsibility for dicing, testing, volume packaging and assembly of PIC-based products. We have quality control processes and quality management
methods in our internal manufacturing operations. Certain of our products are designed and qualified to meet applicable Telcordia Technologies, Inc., TÜV SÜD America Inc. and Underwriters Laboratories Inc. standards. Our manufacturing
facilities in Shenzhen are third-party certified to TL 9000, ISO 9001, ISO 14001 and OHSAS 18000 standards and our facilities in San Jose are certified to ISO 9001 standards.

We use suppliers from the United States, China, Japan and other locations. Although there are multiple sources for most of the component parts of our products, some components are sourced from single or,
in some

##### Table of Contents

cases, limited sources. For example, various types of adhesives are sourced from various manufacturers which presently are sole sources for these particular adhesives. We typically do not have
written agreements with any of these component manufacturers to guarantee the supply of the key components used in our products.

Backlog

Sales of our products generally are made pursuant to purchase orders, often with short lead times. These purchase orders
are typically made without deposits and are often subject to revision or cancellation. The quantities actually purchased by our customers, as well as the shipment schedules, are frequently revised to reflect changes in our customers needs and
in our supply of products. Because of the possibility of changes in delivery or acceptance schedules, cancellations, modifications or price reductions with limited or no penalties, we do not believe that backlog is a reliable indicator of our future
revenue and do not rely on backlog to manage our business or evaluate our performance. Changes in the amount of our backlog do not necessarily reflect a corresponding change in the level of actual or potential sales.

Geographic Areas

We
calculate the percentage of our total revenue to specific regions based on sales to a customer location as follows:

Competition

The market for optical communications systems is highly competitive. While no company competes against us in all of our product areas, our
competitors range from large international companies offering a wide range of products to smaller companies specializing in narrow markets. We believe the principal competitive factors in this market are:



| |  |  | ability to design and manufacture high quality, reliable products;
| | - |  | ------------------------------------------------------------------



| |  |  | breadth of product solutions;
| | - |  | -----------------------------



11



---

##### Table of Contents

| |  |  | price to performance characteristics;
| | - |  | -------------------------------------



| |  |  | financial stability;
| | - |  | --------------------



| |  |  | ability to quickly and consistently produce in high volume and high quality;
| | - |  | ----------------------------------------------------------------------------



| |  |  | ability to meet customers specific requirements;
| | - |  | -------------------------------------------------



| |  |  | ability to meet customer lead time demands; and
| | - |  | -----------------------------------------------



| |  |  | depth of relationships with and proximity to key customers globally.
| | - |  | --------------------------------------------------------------------

We believe we compete favorably with respect to these factors. We believe our principal competitors include Finisar Corporation, JDS
Uniphase Corporation, NTT Electronics Corporation, Source Photonics, Inc. and Sumitomo Electric Device Innovations, Inc. We also compete with various other companies.

Our competitors may have substantially greater name recognition and technical, financial and marketing resources than we do. Many of our competitors have greater resources to develop products or pursue
acquisitions, and more experience in developing or acquiring new products and technologies and in creating market awareness for these products and technologies than we do. In addition, a number of our competitors have the financial resources to
offer competitive products at below market pricing levels that could prevent us from competing effectively and which could adversely affect our financial performance.

We also face competition from some of our customers who evaluate our capabilities against the merits of manufacturing products internally. These customers may have the ability to manufacture competitive
products at a lower cost than we would charge as a result of their higher levels of integration. As a result, these customers may purchase less of our products and there would be additional pressure to lower our selling prices which, accordingly,
would negatively impact our revenue and gross margin.

Employees

As of December 31, 2010, we had 3,112 employees, of which 166 employees were based in our corporate headquarters in San Jose,
California and 2,946 were based in Shenzhen, China. As of that date, we had 110 employees in sales and marketing, 321 employees in research and development, 2,543 employees in manufacturing and operations and 138 employees in general and
administrative functions.

None of our employees are covered by a collective bargaining agreement. Chinese law requires that
all employees be members of a union that is overseen by the Peoples Republic of China. We have never experienced employment-related work stoppages and we consider our employee relations to be good.

Environmental, health and safety matters

Our research and development and manufacturing operations and our products are subject to a variety of environmental, health and safety laws and regulations in the jurisdictions in which we operate. These
regulations govern, among other things, the discharge of pollutants to air, water, and soil; the remediation of soil and groundwater contamination; the use, handling and disposal of hazardous materials; employee health and safety; and the hazardous
material content and recycling of our products. We use, store and dispose of hazardous materials in our manufacturing operations and as components in our products. We incur costs to comply with existing environmental, health and safety requirements,
and any failure to comply, or the identification of contamination for which we are found liable, could cause us to incur additional costs, including cleanup costs, monetary fines, or civil or criminal penalties, or result in the curtailment of our
operations. In addition, environmental, health and safety requirements have become more stringent over time, and changes to existing requirements could restrict our ability to expand our facilities, require us to acquire costly pollution control
equipment, or cause us to incur other significant expenses or to modify our manufacturing processes or the contents of our products. Some jurisdictions in which we operate or sell our products have enacted requirements



12



---

##### Table of Contents

regarding the recycling of waste electronic equipment, and/or the packaging and hazardous material content of certain products. For example, jurisdictions including China and the European Union,
among a growing number of jurisdictions, have placed restrictions on the use of lead, among other chemicals, in electronic products, which affects the composition and packaging of our products. The passage of such requirements in additional
jurisdictions, or the tightening of standards or elimination of certain exemptions in jurisdictions where our products are already subject to such requirements, could cause us to incur significant expenditures to make our products compliant with new
requirements, or could limit the markets into which we may sell our products.

Additionally, increasing efforts to control
emissions of greenhouse gases, or GHG, may also impact us. For example, our semiconductor manufacturing operations in California use perfluorocarbons, which are classified as a high global warming potential greenhouse gas. Californias recently
enacted Global Warming Solutions Act will require us to design and install additional pollution control equipment at our San Jose, California, manufacturing plant to reduce our perfluorocarbon emissions beginning in 2012. In the United States, the
Environmental Protection Agency has announced a finding relating to GHG emissions that may result in promulgation of federal GHG air quality standards. The U.S. Congress has considered various options, including a cap and trade system which would
impose a limit and a price on GHG emissions and establish a market for trading GHG credits. China has recently agreed to join the Copenhagen Climate Accord, a voluntary (and non-binding) GHG agreement. Globally, negotiations for a treaty to succeed
the 1997 Kyoto Protocol Treaty are ongoing, and it is not yet known whether (or on what terms) agreement will be reached on a successor treaty. Additional restrictions, limits, taxes, or other controls on GHG emissions could significantly increase
our operating costs and, while it is not possible to estimate the specific impact any final GHG regulations will have on our operations, there can be no assurance that these measures will not have significant additional impact on us. In addition,
some of our operations might be affected by the physical impacts of climate change. For example, some of our facilities are located in coastal areas that might be vulnerable to changes in sea level.

Corporate Information

We were incorporated in the State of Delaware in October 1996 as NanoGram Corporation, and we changed our name to NeoPhotonics Corporation
in 2002. During 2002 and 2003, we spun out two new companies, NanoGram Devices Corporation, a medical device battery company, and NanoGram Corporation, a nanomaterials applications company. NanoGram Devices was subsequently acquired by Greatbatch
Inc. NanoGram Corporation was acquired by Teijin Limited in July 2010. In November 2003, we filed a petition for relief under Chapter 11 of the federal bankruptcy laws in the United States Bankruptcy Court for the Northern District of California.
Our plan of reorganization was substantially consummated in March 2004, at which point we emerged from bankruptcy. In addition, we have completed several acquisitions as follows:



| |  |  | In March 2003, we acquired Lightwave Microsystems Corporation, a developer and fabricator of photonic integrated circuits;
| | - |  | --------------------------------------------------------------------------------------------------------------------------



| |  |  | In March 2006, we completed the acquisition of Photon Technology Co., Ltd. (now named NeoPhotonics (China) Co., Ltd.), a manufacturer of active
optoelectronics, transceivers and modules;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In June 2006, we acquired Lightconnect, Inc., which expanded our product portfolio by adding a line of micro-electromechanical systems based optical
components and modules;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | In June 2006, we acquired OpTun, Inc., a developer of ROADM technology;

|ITEM 1A. | RISK FACTORS
|-------- | ------------

Risks related to our business

We
have a history of losses which may continue in the future.

We have a history of losses and we may incur additional
losses in future periods. As of December 31, 2010, our accumulated deficit was $215.8 million. We also expect to continue to make significant expenditures related to the development of our business. These include expenditures to hire additional
personnel related to the sales, marketing and development of our products and to maintain and expand our manufacturing facilities and research and development operations.

We are subject to the cyclical nature of the markets in which we compete and any future downturn may reduce demand for our products and revenue.

The markets in which we compete are tied to the aggregate capital expenditures of service providers as they build out and upgrade their
network infrastructure. These markets are highly cyclical and characterized by constant and rapid technological change, price erosion, evolving standards and wide fluctuations in product supply and demand. In the past, these markets have experienced
significant downturns, often connected with, or in anticipation of, the maturation of product cyclesfor both manufacturers and their customers productsand with declining general economic conditions. These downturns have been
characterized by diminished product demand, production overcapacity, high inventory levels and accelerated erosion of average selling prices.

Our historical results of operations have been subject to substantial fluctuations, and we may experience substantial period-to-period fluctuations in future results of operations. Any future downturn in
the markets in which we compete could significantly reduce the demand for our products and therefore may result in a significant reduction in revenue. It may also increase the volatility of the price of our common stock. Our revenue and results
of operations may be materially and adversely affected in the future due to changes in demand from individual customers or cyclical changes in the markets utilizing our products.

In addition, the communications networks industry from time to time has experienced and may again experience a pronounced downturn. To
respond to a downturn, many service providers may slow their capital expenditures, cancel or delay new developments, reduce their workforces and inventories and take a cautious approach to acquiring new equipment and technologies from original
equipment manufacturers, which would have a negative impact on our business. Weakness in the global economy or a future downturn in the communications networks industry may cause our results of operations to fluctuate from quarter-to-quarter and
year-to-year, harm our business, and may increase the volatility of the price of our common stock.

If spending for communications
networks does not continue to grow as expected, our business may suffer.

Our future success as a provider of modules
and subsystems to leading network equipment vendors depends on their continued capital spending on global communications networks. Network traffic has experienced rapid



14



---

##### Table of Contents

growth driven primarily by bandwidth-intensive content, including HD and 3D video, music, social networking, video conferencing and other multimedia. This growth is intensified by the
proliferation of fixed and wireless network-attached devices, including smartphones, laptops, netbooks, tablet computers, PCs, e-readers, televisions and gaming devices, that are enabling consumers to access content at increasing data rates anytime
and anywhere. Our future success depends on continued demand for high-bandwidth, high-speed communications networks and the ability of network equipment vendors to meet this demand. Growth in demand for communications networks is limited by several
factors, including an evolving regulatory environment and uncertainty regarding long-term sustainable business models. We cannot be certain that demand for bandwidth-intensive content will continue to grow in the future. If expectations for growth
of communications networks and bandwidth consumption are not realized and investment in communications networks does not grow as anticipated, our business could be harmed.

We are dependent on Huawei Technologies and our key customers for a significant portion of our revenue and the loss of, or a significant reduction in orders from, Huawei Technologies or any of our
other key customers may reduce our revenue and adversely impact our results of operations.

Historically, we have
generated most of our revenue from a limited number of customers. In 2010, our largest customer, Huawei Technologies, represented 48.3% of our total revenue and our top ten customers represented 88.6% of our total revenue. As a result, the loss of,
or a significant reduction in orders from, Huawei Technologies or any of our other key customers would materially and adversely affect our revenue and results of operations. Adverse events affecting our customers could also adversely affect our
revenue and results of operations (for instance, in 2009, the filing of a voluntary petition for bankruptcy protection by one of our customers, Nortel Networks Limited, has prevented us from timely collection of our accounts receivable from that
customer). In addition, network equipment vendors serving the communications networks industry may continue to consolidate, and we may not be able to offset any potential decline in revenue arising from consolidation of our existing customers with
revenue from new customers.

Customer demand is difficult to accurately forecast and, as a result, we may be unable to optimally match
production with customer demand.

We make planning and spending decisions, including determining the levels of business
that we will seek and accept, production schedules, component procurement commitments, personnel needs and other resource requirements, based on our estimates of customer requirements. The short-term nature of commitments by many of our customers
and the possibility of unexpected changes in demand for their products reduce our ability to accurately estimate future customer requirements. On occasion, customers may require rapid increases in production, which can strain our resources, cause
our manufacturing to be negatively impacted by materials shortages, necessitate higher or more restrictive procurement commitments and reduce our gross margin. We may not have sufficient capacity at any given time to meet the volume demands of our
customers, or one or more of our suppliers may not have sufficient capacity at any given time to meet our volume demands. Conversely, a downturn in the markets in which our customers compete can cause, and in the past have caused, our customers to
significantly reduce or delay the amount of products ordered from us or to cancel existing orders, leading to lower utilization of our facilities. Because many of our costs and operating expenses are relatively fixed, reduction in customer demand
would have a material adverse effect on our gross margin, operating income and cash flow. During an industry downturn, there is also a higher risk that our trade receivables would be uncollectible.

Our products are typically sold pursuant to individual purchase orders or by use of a vendor-managed inventory, or VMI, model, which is a
process by which we ship agreed quantities of products to a customer-designated location and those products remain our inventory and we retain the title and risk of loss for those products until the customer takes possession of the products. While
our customers generally provide us with their demand forecasts and may give us a promised market share award, they are typically not contractually committed to buy any quantity of products beyond firm purchase orders. Many of our customers may
increase, decrease,



15



---

##### Table of Contents

cancel or delay purchase orders already in place. If any of our major customers decrease, stop or delay purchasing our products for any reason, our business and results of operations would be
harmed. Cancellation or delays of such orders may cause us to fail to achieve our short and long-term financial and operating goals.

We
are under continuous pressure to reduce the prices of our products.

The communications networks industry has been
characterized by declining product prices over time. We have reduced the prices of many of our products in the past and we expect to experience pricing pressure for our products in the future. When seeking to maintain or increase their market share,
our competitors may also reduce the prices of their products. In addition, our customers may have the ability to internally develop and manufacture competing products at a lower cost than we would otherwise charge, which would add additional
pressure on us to lower our selling prices. If we are unable to offset any future reductions in our average selling prices by increasing our sales volume, reducing our costs and expenses or introducing new products, our gross margin would suffer.

It could be discovered that our products contain defects that may cause us to incur significant costs, divert our attention, result in
a loss of customers and result in product liability claims.

Our products are complex and undergo quality testing as
well as formal qualification by our customers and us. However, defects may occur from time to time. Our customers testing procedures are limited to evaluating our products under likely and foreseeable failure scenarios and over varying amounts
of time. For various reasons, such as the occurrence of performance problems that are unforeseeable in testing or that are detected only when products age or are operated under peak stress conditions, our products may fail to perform as expected
long after customer acceptance. Failures could result from faulty components or design, problems in manufacturing or other unforeseen reasons. As a result, we could incur significant costs to repair or replace defective products under warranty,
particularly when such failures occur in installed systems. We have experienced such failures in the past and will continue to face this risk going forward, as our products are widely deployed throughout the world in multiple demanding environments
and applications. In addition, we may in certain circumstances honor warranty claims after the warranty has expired or for problems not covered by warranty in order to maintain customer relationships. Any significant product failure could result in
lost future sales of the affected product and other products, as well as customer relations problems, litigation and damage to our reputation.

In addition, our products are typically embedded in, or deployed in conjunction with, our customers products, which incorporate a variety of components, modules and subsystems and may be expected to
interoperate with modules produced by third parties. As a result, not all defects are immediately detectable and when problems occur, it may be difficult to identify the source of the problem. These problems may cause us to incur significant damages
or warranty and repair costs, divert the attention of our engineering personnel from our product development efforts and cause significant customer relations problems or loss of customers, all of which would harm our business.

The occurrence of any defects in our products could give rise to liability for damages caused by such defects. They could, moreover,
impair our customers acceptance of our products. Both could have a material adverse effect on our business and financial condition. Although we carry product liability insurance which covers this risk, this insurance may not adequately cover
our costs arising from defects in our products or otherwise.

Manufacturing problems could result in delays in product shipments to
customers and could adversely affect our revenue, competitive position and reputation.

We may experience delays,
disruptions or quality control problems in our manufacturing operations. For instance, we could experience a disruption in our fabrication facility for our PIC products due to any number of



16



---

##### Table of Contents

reasons, such as equipment failure, contaminated materials or process deviations, which could adversely impact manufacturing yields or delay product shipments. As a result, we could incur
additional costs that would adversely affect our gross margin, and product shipments to our customers could be delayed beyond the shipment schedules requested by our customers, which would negatively affect our revenue, competitive position and
reputation.

Additionally, manufacturing yields depend on a number of factors, including the stability and manufacturability
of the product design, manufacturing improvements gained over cumulative production volumes, the quality and consistency of component parts and the nature and extent of customization requirements by customers. Capacity constraints, raw materials
shortages, logistics issues, labor shortages, the introduction of new product lines and changes in customer requirements, manufacturing facilities or processes, or those of some third party contract manufacturers and suppliers of raw materials and
components have historically caused, and may in the future cause, reduced manufacturing yields, negatively impacting the gross margin on, and our production capacity for, those products. Moreover, an increase in the rejection and rework rate of
products during the quality control process before, during or after manufacture would result in our experiencing lower yields, gross margin and production capacity.

Our ability to maintain sufficient manufacturing yields is particularly challenging with respect to PICs due to the complexity and required precision of a large number of unique manufacturing process
steps. Manufacturing yields for PICs can also suffer if contaminated materials or materials that do not meet highly precise composition requirements are inadvertently utilized. Because a large portion of our PIC manufacturing costs are fixed, PIC
manufacturing yields have a substantial effect on our gross margin. Lower than expected manufacturing yields could also delay product shipments and decrease our revenue.

Natural disasters, terrorist attacks or other catastrophic events could harm our operations.

Our worldwide operations could be subject to natural disasters and other business disruptions, which could harm our future revenue and financial condition and increase our costs and expenses. For example,
the March 2011 earthquake and tsunami in Japan may adversely impact our revenues from customers located in Japan and/or our ability to source parts from companies located in Japan. In addition, our corporate headquarters and wafer fabrication
facility in San Jose, California are located near major earthquake fault lines, and our manufacturing facilities are located in Shenzhen, China, an area that is susceptible to typhoons. Further, a terrorist attack, including one aimed at energy or
communications infrastructure suppliers, could hinder or delay the development and sale of our products. In the event that an earthquake, tsunami, typhoon, terrorist attack or other natural or manmade catastrophe were to destroy any part of our
facilities, destroy or disrupt vital infrastructure systems or interrupt our operations or the facilities or operations of our suppliers or customers for any extended period of time, our business, financial condition and results of operations would
be materially adversely affected. We are not insured against several natural disasters, including earthquakes.

We have a limited
history operating on a global basis, making it difficult to predict our future results of operations.

We have a
limited history operating on a global basis, which makes it difficult to evaluate our business and financial prospects. While our operations began in 1996, we did not begin commercial shipments of our PIC products until the second quarter of 2003
and we did not acquire our subsidiaries in China until 2005. Since then, our revenue, gross margin and results of operations have varied significantly and are likely to continue to vary from quarter to quarter due to a number of factors, many of
which are not within our control. For instance, changes in gross margin may result from various factors, such as changes in pricing, changes in our fixed costs, changes in the cost of labor, changes in the mix of our products sold, changes in the
amount of product manufactured versus the amount of product sold over time, and charges for excess and obsolete inventory. In making an investment decision relating to our common stock, you should evaluate our business in light of the risks,
expenses and difficulties frequently encountered by companies operating on a global platform, particularly

companies in the rapidly changing communications networks industry. It is difficult for us to accurately forecast our future revenue and gross margin and plan expenses accordingly and, therefore,
it is difficult for us to predict our future results of operations.

We must continually achieve new design wins and enhance existing
products or our business may be harmed.

The markets for our products are characterized by frequent new product
introductions, changes in customer requirements and evolving industry standards, all with an underlying pressure to reduce cost and meet stringent reliability and qualification requirements. Our future performance will depend on our successful
development, introduction and market acceptance of new and enhanced products that address these challenges. The anticipated or actual introduction of new and enhanced products by us and by our competitors may cause our customers to defer or cancel
orders for our existing products. In addition, the introduction of new products by us or our competitors could result, and in the past, has resulted, in a slowdown in demand for our existing products and could result, and in the past, has resulted,
in a write-down in the value of inventory. We have both recently and in the past experienced a slowdown in demand for existing products and delays in new product development, and such delays may occur in the future. To the extent customers defer or
cancel orders for our products for any reason or we fail to achieve new design wins, our competitive position would be adversely affected and our ability to grow revenue would be impaired.

Product development delays may result from numerous factors, including:



| |  |  | changing product specifications and customer requirements;
| | - |  | ----------------------------------------------------------



| |  |  | unanticipated engineering complexities
| | - |  | --------------------------------------



| |  |  | difficulties in reallocating engineering resources and overcoming resource limitations; and
| | - |  | -------------------------------------------------------------------------------------------



| |  |  | changing market or competitive product requirements.
| | - |  | ----------------------------------------------------

Furthermore, fast time-to-market with new products can be critical to success in our markets. It is difficult to displace an existing supplier for a particular type of product once a network equipment
vendor has chosen a supplier, even if a later-to-market product provides superior performance or cost efficiency. If we are unable to make our new or enhanced products commercially available on a timely basis, we may lose existing and potential
customers and our financial results would suffer.

The development of new, technologically-advanced products is a complex and
uncertain process requiring frequent innovation, highly-skilled engineering and development personnel and significant capital, as well as the accurate anticipation of technological and market trends. We cannot assure you that we will be able to
identify, develop, manufacture, market or support new or enhanced products successfully, if at all, or on a timely basis. Further, we cannot assure you that our new products will gain market acceptance or that we will be able to respond effectively
to product introductions by competitors, technological changes or emerging industry standards. We also may not be able to develop the underlying core technologies necessary to create new products and enhancements, license these technologies from
third parties, or remain competitive in our markets.

Our success will depend on our ability to anticipate and quickly respond to
evolving technologies and customer requirements.

The communications networks industry is characterized by substantial
investment in new technology and the development of diverse and changing technologies and industry standards. For example, new technologies are required to satisfy the emerging standards for 40Gbps and 100Gbps data transmission in communications
networks.

Our ability to anticipate and respond to evolving technology, industry standards, customer requirements and product
offerings, and to develop and introduce new and enhanced products and technologies, will be critical

##### Table of Contents

factors in our ability to succeed. If we are unable to anticipate and respond to such changes in the future, our competitive position could be adversely affected. In addition, the introduction of
new products by other companies embodying new technologies, or the emergence of new industry standards, could render our existing products uncompetitive from a pricing standpoint, obsolete or otherwise unmarketable.

If our customers do not qualify our products for use, then our results of operations may suffer.

Prior to placing volume purchase orders with us, most of our customers require us to obtain their approvalcalled qualification in
our industryof our new and existing products, and our customers often audit our manufacturing facilities and perform other vendor evaluations during this process. The qualification process involves product sampling and reliability testing and
collaboration with our product management and engineering teams in the design and manufacturing stages. If we are unable to qualify our products with customers, then our revenue would be lower than expected and we may not be able to recover the
costs associated with the qualification process which would have an adverse effect on our results of operations.

In addition,
due to evolving technological changes in our markets, a customer may cancel or modify a design project before we have qualified our product or begun volume manufacturing of a qualified product. It is unlikely that we would be able to recover the
expenses for cancelled or unutilized custom design projects. It is difficult to predict with any certainty whether our customers will delay or terminate product qualification or the frequency with which customers will cancel or modify their
projects, but any such delay, cancellation or modification would have a negative effect on our results of operations.

In
particular, we have developed new technologies and products that we believe are key components in our customers systems for 40Gbps and 100Gbps data transmission. While we are shipping certain products for 40Gbps and 100Gbps system designs
today, many of our products for these systems are currently being qualified for use by our customers. Our ability to successfully qualify and scale capacity for these new technologies and products is important to our ability to grow our business and
market presence. If we are unable to qualify and sell any of these products in volume on time, or at all, our results of operations may be adversely affected.

We face intense competition which could negatively impact our results of operations and market share.

The communications networks industry is highly competitive. Our competitors range from large, international companies offering a wide range of products to smaller companies specializing in niche markets.
In addition, we believe that a number of companies have developed or are developing planar lightwave or MEMS-based, PIC devices and other products that compete directly with our products. Current and potential competitors may have substantially
greater financial, marketing, research and manufacturing resources than we possess, and there can be no assurance that our current and future competitors will not be more successful than us in specific product lines or as a whole.

Some of our competitors have substantially greater name recognition, technical, financial, and marketing resources, and greater
manufacturing capacity, as well as better-established relationships with customers, than we do. Some of our competitors have more resources to develop or acquire, and more experience in developing or acquiring, new products and technologies and in
creating market awareness for these products and technologies. Some of our competitors may be able to develop new products more quickly than us and may be able to develop products that are more reliable or which provide more functionality than ours.
In addition, some of our competitors have the financial resources to offer competitive products at below-market pricing levels that could prevent us from competing effectively and result in a loss of sales or market share or cause us to lower prices
for our products.

We also face competition from some of our customers who evaluate our capabilities against the merits of
manufacturing products internally. Due to the fact that such customers are not seeking to make a profit directly from the manufacture of these products, they may have the ability to manufacture competitive products at a lower



19



---

##### Table of Contents

cost than we would charge such customers. As a result, these customers may purchase less of our products and there would be additional pressure to lower our selling prices which, accordingly,
would negatively impact our revenue and gross margin.

In particular we have developed new technologies and products that are
key components in our customers system designs for 40Gbps and 100Gbps data transmission. The emergence of technologies and products from our competitors and their success in competing against our technologies and products for 40Gbps and
100Gbps data transmission could render our existing products uncompetitive from a pricing standpoint, obsolete or otherwise unmarketable.

Intense competition in our markets could result in aggressive business tactics by our competitors, including aggressively pricing their products or selling older inventory at a discount. If our current or
future competitors utilize aggressive business tactics, including those described above, demand for our products could decline, we could experience delays or cancellations of customer orders, or we could be required to reduce our sales prices.

If we fail to retain our key personnel or if we fail to attract additional qualified personnel, we may not be able to achieve our
anticipated level of growth and our business could suffer.

Our success and ability to implement our business strategy
depends upon the continued contributions of our senior management team and others, including our technical and operations employees. Our future success depends, in part, on our ability to attract and retain key personnel, including our senior
management and others, and on the continued contributions of members of our senior management team and key technical and operations personnel, each of whom would be difficult to replace. The loss of services of members of our senior management team
or key personnel or the inability to continue to attract and retain qualified personnel could have a material adverse effect on our business. Competition for highly skilled technical and operations people, both in the United States and China, is
extremely intense, and we continue to face challenges identifying, hiring and retaining qualified personnel in many areas of our business. If we fail to retain our senior management and other key personnel or if we fail to attract additional
qualified personnel, our business could suffer.

The communications networks industry has long product development cycles requiring us
to incur product development costs without assurances of an acceptable investment return.

The communications networks
industry is highly capital-intensive. Large volumes of equipment and support structures are installed with considerable expenditures of funds and other resources, and long investment return period expectations. At the component supplier level, this
reluctance creates considerable, typically multi-year, gaps between the commencement of new product development and volume purchases. Accordingly, we and our competitors often incur significant research and development and sales and marketing costs
for products that, at the earliest, will be purchased by our customers long after much of the cost is incurred and, in some cases, may never be purchased due to changes in industry or customer requirements in the interim.

Due to changing industry and customer requirements, we are constantly developing new products, including seeking to further integrate
functions on PICs and developing and using new technologies in our products. These development activities can and are expected to necessitate significant investment of capital. Our new products often require a long time to develop because of their
complexity and rigorous testing and qualification requirements. Additionally, developing a manufacturing approach with an acceptable cost structure and yield for new products can be expensive and time-consuming. Due to the costs and length of
research and development and manufacturing process cycles, we may not recognize revenue from new products until long after such expenditures are incurred, if at all, and our gross margin may decrease if our costs are higher than expected.

While we rely on many suppliers, there are a few which, if they stopped, decreased or delayed shipments to us, it could have an adverse
effect on our business.

We depend on a limited number of suppliers for certain components and materials we have
qualified to use in the manufacture of certain of our products. Some of these suppliers could disrupt our business if they stop,



20



---

##### Table of Contents

decrease or delay shipments or if the components they ship have quality, business continuity such as if there is a disruption relating to the earthquake and tsunami in Japan or consistency
issues. Some of these components and materials are available only from a sole source, or have been qualified only from a single source, although other sources may exist. For example, we use various types of adhesives that are sourced from various
manufacturers, which presently are sole sources for these particular adhesives. Furthermore, there are a limited number of entities from which we could obtain certain other components and materials. We may also face component shortages if we
experience increased demand for components beyond what our qualified suppliers can deliver. We have experienced component shortages from certain key suppliers, which has resulted and, if this occurs in the future, may result in an inability to meet
customer demand, higher purchasing costs, or both. Although we engage in various actions to mitigate the impact of these shortages, any inability on our part to obtain sufficient quantities of critical components at reasonable costs could adversely
affect our ability to meet demand for our products, which could cause our revenue, results of operations, or both to suffer.

Our customers generally restrict our ability to change the component parts in our modules without their approval. For more critical
components, such as PICs, lasers and photodetectors, any changes may require repeating the entire qualification process. We typically have not entered into long-term or written agreements with our suppliers to guarantee the supply of the key
components used in our products, and, therefore, our suppliers could stop supplying materials and equipment at any time or fail to supply adequate quantities of component parts on a timely basis. It is difficult, costly, time consuming and, on short
notice, sometimes impossible for us to identify and qualify new component suppliers. The reliance on a sole supplier, single qualified vendor or limited number of suppliers could result in delivery and quality problems, reduced control over product
pricing, reliability and performance and an inability to identify and qualify another supplier in a timely manner. We have in the past had to change suppliers, which has, in some instances, resulted in delays in product development and manufacturing
and loss of revenue. Any such delays in the future may limit our ability to respond to changes in customer and market demands. Any supply deficiencies relating to the quality, quantities or timeliness of delivery of components that we use to
manufacture our products could adversely affect our ability to fulfill our customer orders and our results of operations.

If we fail to
protect, or incur significant costs in defending, our intellectual property and other proprietary rights, our business and results of operations could be materially harmed.

Our success depends to a significant degree on our ability to protect our intellectual property and other proprietary rights. We rely on a
combination of patent, trademark, copyright, trade secret and unfair competition laws, as well as license agreements and other contractual provisions, to establish and protect our intellectual property and other proprietary rights. We have applied
for patent registrations in the United States and in other foreign countries, some of which have been issued. In addition, we have registered the trademark NeoPhotonics in the United States. We cannot guarantee that our pending
applications will be approved by the applicable governmental authorities. Moreover, our existing and future patents and trademarks may not be sufficiently broad to protect our proprietary rights or may be held invalid or unenforceable in
court. A failure to obtain patents or trademark registrations or a successful challenge to our registrations in the United States or other foreign countries may limit our ability to protect the intellectual property rights that these applications
and registrations intended to cover.

Policing unauthorized use of our technology is difficult and we cannot be certain that
the steps we have taken will prevent the misappropriation, unauthorized use or other infringement of our intellectual property rights. Further, we may not be able to effectively protect our intellectual property rights from misappropriation or other
infringement in foreign countries where we have not applied for patent protections, and where effective patent, trademark, trade secret and other intellectual property laws may be unavailable, or may not protect our proprietary rights as fully
as U.S. law. Particularly, our U.S. patents do not afford any intellectual property protection in China, where we have substantial operations. We seek to secure, to the extent possible, comparable intellectual property protections in China. However,
while we have issued patents and pending patent applications in China, portions of our intellectual property portfolio are not yet protected by patents in China. Moreover, the level of protection afforded by patent and other laws in China may not be
comparable to that afforded in the United States.

##### Table of Contents

We attempt to protect our intellectual property, including our trade secrets and know-how,
through the use of trade secret and other intellectual property laws, and contractual provisions. We enter into confidentiality and invention assignment agreements with our employees and independent consultants. We also use non-disclosure agreements
with other third parties who may have access to our proprietary technologies and information. Such measures, however, provide only limited protection, and there can be no assurance that our confidentiality and non-disclosure agreements will not be
breached, especially after our employees or those of our third-party contract manufacturers end their employment or engagement, and that our trade secrets will not otherwise become known by competitors or that we will have adequate remedies in the
event of unauthorized use or disclosure of proprietary information. Unauthorized third parties may try to copy or reverse engineer our products or portions of our products, otherwise obtain and use our intellectual property, or may independently
develop similar or equivalent trade secrets or know-how. If we fail to protect our intellectual property and other proprietary rights, or if such intellectual property and proprietary rights are infringed or misappropriated, our business, results of
operations or financial condition could be materially harmed.

In the future, we may need to take legal actions to prevent
third parties from infringing upon or misappropriating our intellectual property or from otherwise gaining access to our technology. Protecting and enforcing our intellectual property rights and determining their validity and scope could result in
significant litigation costs and require significant time and attention from our technical and management personnel, which could significantly harm our business. In addition, we may not prevail in such proceedings. An adverse outcome of such
proceedings may reduce our competitive advantage or otherwise harm our financial condition and our business.

We may be involved in
intellectual property disputes in the future, which could divert managements attention, cause us to incur significant costs and prevent us from selling or using the challenged technology.

Participants in the markets in which we sell our products have experienced frequent litigation regarding patent and other intellectual
property rights. Numerous patents in these industries are held by others, including our competitors. In addition, from time to time, we have been notified that we may be infringing certain patents or other intellectual property rights of others.
Regardless of their merit, responding to such claims can be time consuming, divert managements attention and resources and may cause us to incur significant expenses. In addition, there can be no assurance that third parties will not assert
infringement claims against us. While we believe that our products do not infringe in any material respect upon intellectual property rights of other parties and/or meritorious defense would exist with respect to any assertions to the contrary, we
cannot be certain that our products would not be found infringing the intellectual property rights of others. Intellectual property claims against us could invalidate our proprietary rights and force us to do one or more of the following:



| |  |  | obtain from a third party claiming infringement a license to sell or use the relevant technology, which may not be available on reasonable terms, or at
all;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | stop manufacturing, selling, incorporating or using our products that use the challenged intellectual property;
| | - |  | ---------------------------------------------------------------------------------------------------------------



| |  |  | pay substantial monetary damages; or
| | - |  | ------------------------------------



| |  |  | expend significant resources to redesign the products that use the technology and to develop non-infringing technology.
| | - |  | -----------------------------------------------------------------------------------------------------------------------

Any of these actions could result in a substantial reduction in our revenue and could result in losses over an extended period of time.

On January 5, 2010, Finisar Corporation, or Finisar, filed a complaint in the United States District Court for the
Northern District of California against Source Photonics, Inc., MRV Communications, Inc., Oplink Communications, Inc. and us, or collectively, the co-defendants. In the complaint, Finisar alleged infringement of certain of its U.S. patents arising
from the co-defendants respective manufacture, importation, use, sale of or



22

##### Table of Contents

offer to sell certain optical transceiver products in the United States. Finisar sought to recover unspecified damages, up to treble the amount of actual damages, together with attorneys
fees, interest and costs. Finisar alleged that at least some of the patents asserted are a part of certain digital diagnostic standards for optoelectronics transceivers and, therefore, are being utilized in such digital diagnostic standards. On
March 23, 2010, we filed an answer to the complaint and counterclaims, asserting two claims of patent infringement and additional claims asserting that Finisar has violated state and federal competition laws and violated its obligations to
license on reasonable and non-discriminatory terms. On May 5, 2010, the court dismissed without prejudice all co-defendants (including us) except Source Photonics, Inc., on grounds that such claims should have been asserted in four separate
lawsuits, one against each co-defendant. This dismissal without prejudice does not prevent Finisar from bringing a new similar lawsuit against us. We and Finisar had agreed to a 90 day tolling of our respective claims and not to refile any claims
against each other until one or more specified events occur resulting in the partial or complete resolution of the litigation between Source Photonics and Finisar. On September 10, 2010, Source Photonics and Finisar settled their lawsuit,
commencing the tolling period, which expired in early December 2010.

On January 18, 2011, we and Finisar again agreed to
toll our respective claims and not to refile the originally asserted claims against each other until at least 90 days after on or more specified events occur resulting in the partial or complete resolution of litigation involving the same Finisar
patents between Oplink Communications, Inc. and Finisar. At that time, Finisar will be permitted to bring a new lawsuit against us if they choose to do so. If we are unsuccessful in our defense of the Finisar patent infringement claims, a license to
use the allegedly infringing technology may not be available to us at all, and if it is, it may not be available on commercially reasonable terms and therefore may limit or preclude us from competing in the market for optical transceivers in the
United States, which may have a material adverse effect on our results of operations and financial condition, and otherwise materially harm our business.

Although we believe that we would have meritorious defenses to the infringement allegations and intend to defend any new similar lawsuit vigorously, there can be no assurance that we will be successful in
our defense. Even if we are successful, we may incur substantial legal fees and other costs in defending the lawsuit. Further, a new lawsuit, if brought, would be likely to divert the efforts and attention of our management and technical personnel,
which could harm our business.

If we fail to obtain the right to use the intellectual property rights of others which are necessary to
operate our business, and to protect their intellectual property, our ability to succeed will be adversely affected.

From time to time we may choose to or be required to license technology or intellectual property from third parties in connection with the
development of our products. We cannot assure you that third-party licenses will be available to us on commercially reasonable terms, if at all. Generally, a license, if granted, would include payments of up-front fees, ongoing royalties or both.
These payments or other terms could have a significant adverse impact on our results of operations. The inability to obtain a necessary third-party license required for our product offerings or to develop new products and product enhancements could
require us to substitute technology of lower quality or performance standards, or of greater cost, either of which could adversely affect our business. If we are not able to obtain licenses from third parties, if necessary, then we may also be
subject to litigation to defend against infringement claims from these third parties. Our competitors may be able to obtain licenses or cross-license their technology on better terms than we can, which could put us at a competitive disadvantage.
Also, we typically enter into confidentiality agreements with such third parties in which we agree to protect and maintain their proprietary and confidential information, including requiring our employees to enter into agreements protecting such
information. There can be no assurance that the confidentiality agreements will not be breached by any of our employees or that such third parties will not make claims that their proprietary information has been disclosed.

Any potential dispute involving our patents or other intellectual property could also include our
customers using our products, which could trigger our indemnification obligations to them and result in substantial expenses to us.

In any potential dispute involving our patents or other intellectual property, our customers could also become the target of litigation. Because we often indemnify our customers for intellectual property
claims made against them for products incorporating our technology, any claims against our customers could trigger indemnification obligations in some of our supply agreements, which could result in substantial expenses such as increased legal
expenses, damages for past infringement or royalties for future use. While we have not incurred any indemnification expenses to date, any future indemnity claim could adversely affect our relationships with our customers and result in substantial
costs to us. Our insurance does not cover intellectual property infringement.

If we fail to adequately manage our long-term growth and
expansion requirements, our business will suffer.

In recent years, we have experienced significant growth through,
among other things, internal expansion programs, product development and acquisitions of other companies. We expect to continue to grow, which could require us to expand our manufacturing operations, including hiring new personnel, purchasing
additional equipment, leasing or purchasing additional facilities, developing the management infrastructure and developing our suppliers to manage any such expansion. If we fail to secure these expansion requirements or manage our future growth
effectively, our business could suffer.

Rapidly changing standards and regulations could make our products obsolete, which would cause
our revenue and results of operations to suffer.

We design our products to conform to regulations established by
governments and to standards set by industry standards bodies worldwide, such as The American National Standards Institute, the European Telecommunications Standards Institute, the International Telecommunications Union and the Institute of
Electrical and Electronics Engineers, Inc. Various industry organizations are currently considering whether and to what extent to create standards for elements used in 100Gbps systems. Because certain of our products are designed to
conform to current specific industry standards, if competing or new standards emerge that are preferred by our customers, we would have to make significant expenditures to develop new products. If our customers adopt new or competing industry
standards with which our products are not compatible, or the industry groups adopt standards or governments issue regulations with which our products are not compatible, our existing products would become less desirable to our customers and our
revenue and results of operations would suffer.

Potential future acquisitions could be difficult to integrate, divert the attention of
key personnel, disrupt our business, dilute stockholder value and impair our financial results.

As part of our
business strategy, we have pursued and intend to continue to pursue acquisitions of complementary businesses, products, services or technologies that we believe could accelerate our ability to compete in our existing markets or allow us to enter new
markets.

Acquisitions involve numerous risks, any of which could harm our business, including:



| |  |  | difficulties in integrating the operations, technologies, products, existing contracts, accounting and personnel of the target company and realizing
the anticipated synergies of the combined businesses;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | difficulties in supporting and transitioning customers, if any, of the target company;
| | - |  | --------------------------------------------------------------------------------------



| |  |  | diversion of financial and management resources from existing operations;
| | - |  | -------------------------------------------------------------------------



| |  |  | the price we pay or other resources that we devote may exceed the value we realize, or the value we could have realized if we had allocated the
purchase price or other resources to another opportunity;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

##### Table of Contents

| |  |  | risks of entering new markets in which we have limited or no experience;
| | - |  | ------------------------------------------------------------------------



| |  |  | potential loss of key employees, customers and strategic alliances from either our current business or the target companys business;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------



| |  |  | assumption of unanticipated problems or latent liabilities, such as problems with the quality of the target companys products;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------



| |  |  | inability to generate sufficient revenue to offset acquisition costs;
| | - |  | ---------------------------------------------------------------------



| |  |  | dilutive effect on our stock as a result of any equity-based acquisitions; and
| | - |  | ------------------------------------------------------------------------------



| |  |  | in the event of international acquisitions, risks associated with accounting and business practices that are different from applicable U.S. practices
and requirements.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------

Acquisitions also frequently result in the recording of goodwill and other intangible
assets which are subject to potential impairments which have occurred in the past and which, were they to occur in the future, could harm our financial results. As a result, if we fail to properly evaluate acquisitions or investments, we may not
achieve the anticipated benefits of any such acquisitions, and we may incur costs in excess of what we anticipate. The failure to successfully evaluate and execute acquisitions or investments or otherwise adequately address these risks could
materially harm our business and financial results.

Potential changes in our effective tax rate could harm our future results.

We are subject to income taxes in China and the United States and various foreign jurisdictions, and our domestic and
international tax liabilities are subject to the allocation of expenses in differing jurisdictions. Our tax rate is affected by changes in the mix of earnings and losses in countries with differing statutory tax rates, certain non-deductible
expenses arising from the requirement to expense stock options and the valuation of deferred tax assets and liabilities, including our ability to utilize our net operating losses. Increases in our effective tax rate could harm our results of
operations.

Our future results of operations may be subject to volatility as a result of exposure to fluctuations in foreign exchange
rates, primarily the RMB/U.S. dollar exchange rate.

We are exposed to foreign exchange risks. Foreign currency
fluctuations may adversely affect our revenue and our costs and expenses, and hence our results of operations. A substantial portion of our business is conducted through our subsidiaries based in China, whose functional currency is the RMB. The
value of the RMB against the U.S. dollar and other currencies may fluctuate and is affected by, among other things, changes in political and economic conditions. Since July 21, 2005, the RMB has no longer been pegged solely to the value of the
U.S. dollar. Instead, the RMB is now pegged against a basket of currencies, determined by the Peoples Bank of China, against which it can rise or fall by as much as 0.5% each day. This change in policy has resulted in approximately 20%
appreciation of the RMB against the U.S. dollar between July 21, 2005 and December 31, 2010. While the international reaction to the RMB revaluation has generally been positive, there remains significant international pressure on the
Chinese government to adopt an even more flexible currency policy, which may result in a further and more significant appreciation of the RMB against the U.S. dollar. In the long term, the RMB may appreciate or depreciate significantly in value
against the U.S. dollar, depending upon the fluctuation of the basket of currencies against which it is currently valued, or it may be permitted to enter into a full float, which may also result in a significant appreciation or depreciation of the
RMB against the U.S. dollar.

Foreign currency exchange rates are subject to fluctuation and may cause us to recognize
transaction gains and losses in our statements of operations. To the extent that transactions by our subsidiaries in China are denominated in currencies other than the RMB, we bear the risk that fluctuations in the exchange rates of the RMB in
relation to other currencies could decrease our revenue or increase our costs and expenses, therefore having an adverse effect on our future results of operations.

##### Table of Contents

While we generate the majority of our revenue in RMB, conversely, a majority of our
operating expenses are in U.S. dollars. Therefore, depreciation in the RMB against the U.S. dollar would adversely impact our revenue upon translation to U.S. dollars, but the positive impact on operating expenses would be less. This would result in
an overall adverse effect on our results of operations and financial position. For example, for the year ended December 31, 2010, a 10% appreciation in RMB against the U.S. dollar would have resulted in a $13.0 million decrease in our revenue
and a $1.5 million decrease in our net income for the period.

To date, we have not entered into any hedging transactions
in an effort to reduce our exposure to foreign currency exchange risk. While we may decide to enter into hedging transactions in the future, the availability and effectiveness of these hedging transactions may be limited and we may not be able to
successfully hedge our exposure. In addition, our currency exchange variations may be magnified by Chinese exchange control regulations that restrict our ability to convert RMB into foreign currency.

We face a variety of risks associated with international sales and operations.

We currently derive, and expect to continue to derive, a significant portion of our revenue from international sales in various markets.
In addition, a major portion of our operations is based in Shenzhen, China. Our international revenue and operations are subject to a number of material risks, including, but not limited to:



| |  |  | difficulties in staffing, managing and supporting operations in more than one country;
| | - |  | --------------------------------------------------------------------------------------



| |  |  | difficulties in enforcing agreements and collecting receivables through foreign legal systems;
| | - |  | ----------------------------------------------------------------------------------------------



| |  |  | fewer legal protections for intellectual property in foreign jurisdictions;

Negative developments in any of these areas in China or other countries could result in a reduction in
demand for our products, the cancellation or delay of orders already placed, difficulties in producing and delivering our products, threats to our intellectual property, difficulty in collecting receivables, and a higher cost of doing business. In
addition, although we maintain an anti-corruption compliance program throughout the company, violations of our compliance program may result in criminal or civil sanctions, including material monetary fines, penalties and other costs against us or
our employees, and may have a material adverse effect on our business.

We are subject to governmental export and import controls that could subject us to liability or impair
our ability to compete in international markets.

We are subject to export control laws, regulations and requirements
that limit which products we sell and where and to whom we sell our products, especially laser-dependent products. In some cases, it is possible that export licenses would be required from U.S. government agencies for some of our products in
accordance with various statutory authorities, including but not limited to the International Traffic in Arms Regulations, the Export Administration Act of 1979, the International Emergency Economic Powers Act of 1977, the Trading with the Enemy Act
of 1917 and the Arms Export Control Act of 1976 and various country-specific trade sanctions legislation. In addition, various countries regulate the import of certain technologies and have enacted laws that could limit our ability to
distribute our products. We may not be successful in obtaining the necessary export and import licenses. Failure to comply with these and similar laws on a timely basis, or at all, or any limitation on our ability to export or sell our
products would adversely affect our business, financial condition and results of operations.

Changes in our products or
changes in export and import laws and implementing regulations may create delays in the introduction of new products in international markets, prevent our customers from deploying our products internationally or, in some cases, prevent the export or
import of our products to certain countries altogether. Any change in export or import regulations or related legislation, shift in approach to the enforcement or scope of existing regulations, or change in the countries, persons or
technologies targeted by such regulations, could result in decreased use of our products by, or in our decreased ability to export or sell our products to, existing or potential customers with international operations. In such event, our
business and results of operations could be adversely affected.

If we fail to maintain effective internal control over financial
reporting in the future, the accuracy and timing of our financial reporting may be adversely affected.

Preparing our
consolidated financial statements involves a number of complex manual and automated processes, which are dependent upon individual data input or review and require significant management judgment. One or more of these elements may result in errors
that may not be detected and could result in a material misstatement of our consolidated financial statements. In 2007, we implemented Oracle eBusiness suite software to automate certain business operations and internal reporting activities. While
automation is intended to decrease the likelihood for error and enhance our ability to detect errors that could arise, we expect that for the foreseeable future we will have procedures that are manually intensive.

If a material misstatement occurs in the future, we may fail to meet our future reporting obligations, we may need to restate our
financial results and the price of our common stock may decline. Any failure of our internal controls could also adversely affect the results of the periodic management evaluations and annual independent registered public accounting firm attestation
reports regarding the effectiveness of our internal control over financial reporting that will be required when the rules of the Securities and Exchange Commission, or the SEC, under Section 404 of the Sarbanes-Oxley Act, become applicable to
us beginning with the filing of our Annual Report on Form 10-K for the year ending December 31, 2011. Effective internal controls are necessary for us to produce reliable financial reports and are important to helping prevent financial fraud.
If we cannot provide reliable financial reports or prevent fraud, our business and results of operations could be harmed, investors could lose confidence in our reported financial information, and the trading price of our stock could drop
significantly.

Covenants in our credit facilities may limit our flexibility in responding to business opportunities and competitive
developments and increase our vulnerability to adverse economic or industry conditions.

We have lending arrangements
with several financial institutions, including a loan and security agreement with Comerica Bank in the United States, and our subsidiaries in China have several line of credit arrangements. Our U.S. loan and security agreement requires us to
maintain certain financial covenants, including a liquidity



27

##### Table of Contents

ratio, and restricts our ability to take certain actions such as incurring additional debt, paying dividends, or engaging in certain transactions like mergers and acquisitions, investments and
asset sales. These restrictions may limit our flexibility in responding to business opportunities, competitive developments and adverse economic or industry conditions. In addition, our obligations under our U.S. loan and security agreement with
Comerica Bank are secured by substantially all of our U.S. assets other than intellectual property assets, which limits our ability to provide collateral for additional financing. A breach of any of these covenants, or a failure to pay interest or
indebtedness when due under any of our credit facilities, could result in a variety of adverse consequences, including the acceleration of our indebtedness.

We may be unable to utilize our net operating loss carryforwards to reduce our income taxes.

As of December 31, 2010, we had net operating loss, or NOL, carryforwards for U.S. federal and state tax purposes of $138.4 million and $47.3 million, respectively. If not utilized, these NOL
carryforwards expire, beginning in 2011. The utilization of the NOL and tax credit carryfowards are subject to a substantial limitation imposed by Section 382 of the Internal Revenue Code of 1986, as amended, or the Code, and similar state
provisions. We recorded deferred tax assets, net of valuation allowance, for the NOL carryforwards currently available after considering the existing Section 382 limitation. If we incur an additional limitation under Section 382, then the
NOL carryforwards, as disclosed, could be reduced by the impact of any future limitation that would result in existing NOL carryforwards and tax credit carryforwards expiring unutilized.

We incur increased costs as a result of operating as a public company, and our management is required to devote substantial time to new compliance initiatives.

We became a public reporting company in February 2011. As a public company, we incur legal, accounting and other expenses that we did not
incur as a private company. In addition, the Sarbanes-Oxley Act, as well as rules subsequently implemented by the SEC and the New York Stock Exchange, imposes additional requirements on public companies, including specific corporate governance
practices. For example, the listing requirements of the New York Stock Exchange require that we satisfy certain corporate governance requirements relating to independent directors, audit and compensation committees, distribution of annual and
interim reports, stockholder meetings, stockholder approvals, solicitation of proxies, conflicts of interest, stockholder voting rights and codes of conduct. Our management and other personnel need to devote a substantial amount of time to these
compliance initiatives. Moreover, these rules and regulations increase our legal and financial compliance costs and make some activities more time-consuming and costly. For example, these rules and regulations may make it more difficult and more
expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced policy limits and coverage or incur substantial additional costs to maintain the same or similar coverage. These rules and regulations
could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board committees or as executive officers.

We are subject to government regulations that could adversely impact our business.

The Federal Communications Commission, or FCC, has jurisdiction over the entire U.S. telecommunications industry and, as a result, our products and our U.S. customers are subject to FCC rules and
regulations. Current and future FCC regulations affecting communications services, our products or our customers businesses could negatively affect our business. In addition, international regulatory standards could impair our ability to
develop products for international customers in the future. Delays caused by our compliance with regulatory requirements could result in postponements or cancellations of product orders. Further, we may not be successful in obtaining or maintaining
any regulatory approvals that may, in the future, be required to operate our business. Any failure to obtain such approvals could harm our business and results of operations.

In some instances, we rely on third-party sales representatives and distributors to assist in selling
our products, and the failure of these representatives and distributors to perform as expected could reduce our future revenue.

Although we primarily sell our products through direct sales to systems vendors, we also sell our products to some of our customers through third-party sales representatives and distributors. Many of our
third-party sales representatives and distributors also market and sell competing products from our competitors. Our third-party sales representatives and distributors may terminate their relationships with us at any time, or with short notice.
Our future performance will also depend, in part, on our ability to attract additional third-party sales representatives and distributors that will be able to market and support our products effectively, especially in markets in which we have not
previously distributed our products. If our current third-party sales representatives and distributors fail to perform as expected, our revenue and results of operations could be harmed.

We are subject to environmental, health and safety laws and regulations, which could subject us to liabilities, increase our costs, or restrict our business or operations in the future.

Our manufacturing operations and our products are subject to a variety of federal, state, local and international
environmental, health and safety laws and regulations in each of the jurisdictions in which we operate or sell our products. These laws and regulations govern, among other things, air emissions, wastewater discharges, the handling and disposal of
hazardous substances and wastes, soil and groundwater contamination, employee health and safety, and the use of hazardous materials in, and the recycling of, our products. Our failure to comply with present and future environmental, health or safety
requirements, or the identification of contamination, could cause us to incur substantial costs, including cleanup costs, monetary fines, civil or criminal penalties, or curtailment of operations. In addition, these laws and regulations have
increasingly become more stringent over time. The identification of presently unidentified environmental conditions, more vigorous enforcement of current environmental, health and safety requirements by regulatory agencies, the enactment of more
stringent laws and regulations, or other unanticipated events could restrict our ability to expand our facilities, require us to install costly pollution control equipment or incur other additional expenses, or require us to modify our manufacturing
processes or the contents of our products, which could have a material adverse effect on our business, financial condition and results of operations.

Our manufacturing facilities use, store and dispose of hazardous substances in connection with their processes. In addition, our operations have grown through acquisitions, and it is possible that
businesses that we have acquired may expose us to environmental liabilities that have not yet been discovered associated with historical site conditions or offsite locations. Some environmental laws impose liability for contamination on current and
former owners and operators of affected sites, or on parties that generated wastes disposed of at off-site locations, regardless of fault. In the event we are found liable for any such contamination in the future, there can be no assurance that
remediation costs, or potential claims for personal injury or property or natural resource damages resulting from contamination, will not be material.

Additionally, increasing efforts to control emissions of greenhouse gases, or GHG, may also impact us. For example Californias recently enacted Global Warming Solutions Act will require us to design
and install additional pollution control equipment at our San Jose, California, manufacturing plant. Additional climate change or GHG control requirements are under consideration at the federal level in the United States and in China. Additional
restrictions, limits, taxes, or other controls on GHG emissions could increase our operating costs and, while it is not possible to estimate the specific impact any final GHG regulations will have on our operations, there can be no assurance that
these measures will not have significant additional impact on us.

We may not be able to obtain capital when desired on favorable terms,
if at all, or without dilution to our stockholders.

We believe that our existing cash and cash equivalents, and cash
flows from our operating activities, will be sufficient to meet our anticipated cash needs for at least the next 12 months. We operate in an industry, however,

##### Table of Contents

that makes our prospects difficult to evaluate. It is possible that we may not generate sufficient cash flow from operations or otherwise have the capital resources to meet our future capital
needs. If this occurs, we may need additional financing to execute on our current or future business strategies, including to:



| |  |  | invest in our research and development efforts by hiring additional technical and other personnel;
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | expand our operating or manufacturing infrastructure;
| | - |  | -----------------------------------------------------



| |  |  | acquire complementary businesses, products, services or technologies; or
| | - |  | ------------------------------------------------------------------------



| |  |  | otherwise pursue our strategic plans and respond to competitive pressures.
| | - |  | --------------------------------------------------------------------------

If we raise additional funds through the issuance of equity or convertible debt securities, the percentage ownership of our stockholders
could be significantly diluted, and these newly-issued securities may have rights, preferences or privileges senior to those of existing stockholders, including those acquiring shares in our initial public offering. We cannot assure you that
additional financing will be available on terms favorable to us, or at all. If adequate funds are not available or are not available on acceptable terms, if and when needed, our ability to fund our operations, take advantage of unanticipated
opportunities, develop or enhance our products, or otherwise respond to competitive pressures could be significantly limited.

Risks
related to our operations in China

Our business operations conducted in China are critical to our success. A total of
$107.3 million, or 58%, of our revenue in 2010 was recognized from customers located in China. Additionally, a substantial portion of our property, plant and equipment, 74% as of December 31, 2010, is located in China. We expect to make further
investments in China in the foreseeable future. Therefore, our business, financial condition, results of operations and prospects are to a significant degree subject to economic, political, legal, and social events and developments in China.

Adverse changes in economic and political policies in China, or Chinese laws or regulations could have a material adverse effect on
business conditions and the overall economic growth of China, which could adversely affect our business.

The Chinese
economy differs from the economies of most developed countries in many respects, including the level of government involvement, level of development, growth rate, control of foreign exchange and allocation of resources. The Chinese economy has been
transitioning from a planned economy to a more market-oriented economy. Despite reforms, the government continues to exercise significant control over Chinas economic growth by way of the allocation of resources, control over foreign
currency-denominated obligations and monetary policy and provision of preferential treatment to particular industries or companies. Moreover, the laws, regulations and legal requirements in China, including the laws that apply to foreign-invested
enterprises are relatively new and are subject to frequent changes. The interpretation and enforcement of such laws is uncertain. Any adverse changes to these laws, regulations and legal requirements, including tax laws, or their interpretation or
enforcement could have a material adverse effect on our business.

Furthermore, while Chinas economy has experienced
rapid growth in the past 20 years, growth has been uneven across different regions, among various economic sectors and over time. China has also in the past and may in the future experience economic downturns due to, for example, government
austerity measures, changes in government policies relating to capital spending, limitations placed on the ability of commercial banks to make loans, reduced levels of exports and international trade, inflation, lack of financial liquidity, stock
market volatility and global economic conditions. Any of these developments could contribute to a decline in business and consumer spending in addition to other adverse market conditions, which could adversely affect our business.

The termination and expiration or unavailability of our preferential income tax treatments in China
may have a material adverse effect on our operating results.

Prior to January 1, 2008, entities established in
China were generally subject to a 30% state and 3% local enterprise income tax rate. In accordance with the China Income Tax Law for Enterprises with Foreign Investment and Foreign Enterprises, effective through December 31, 2007, our
subsidiaries in China enjoyed preferential income tax rates. Effective January 1, 2008, the China Enterprise Income Tax Law, or the EIT law, imposes a single uniform income tax rate of 25% on all Chinese enterprises, including foreign-invested
enterprises, and eliminates or modifies most of the tax exemptions, reductions and preferential treatment available under the previous tax laws and regulations. As a result, our subsidiaries in China may be subject to the uniform income tax rate of
25% unless we are able to qualify for preferential status. Currently, we have qualified for a preferential 15% tax rate that is available for new and high technology enterprises. The preferential rate applies to 2010, 2009 and 2008. We realized
benefits from this 10% reduction in tax rate of $1.7 million, $1.0 million and $0.2 million for 2010, 2009, and 2008, respectively. We intend to reapply for the preferential rate for 2011. If approved, the income tax rate will remain at 15%,
otherwise, we anticipate that our income tax rate in China will be 24% for 2011 and 25% thereafter.

Our subsidiaries in China are
subject to restrictions on dividend payments, on making other payments to us or any other affiliated company, and on borrowing or allocating tax losses among our subsidiaries.

Current Chinese regulations permit our subsidiaries in China to pay dividends only out of their accumulated profits, if any, determined in
accordance with Chinese accounting standards and regulations, which are different than U.S. accounting standards and regulations. In addition, our subsidiaries in China are required to set aside at least 10% of their respective accumulated profits
each year, if any, to fund their statutory common reserves until such reserves have reached at least 50% of their respective registered capital. As of December 31, 2010, our Chinese subsidiaries common reserves had not reached this
threshold and, accordingly, these entities are required to continue funding such reserves with accumulated net profits. The statutory common reserves are not distributable as cash dividends except in the event of liquidation. In addition, current
Chinese regulations prohibit inter-company borrowings or allocation of tax losses among subsidiaries in China. Further, if our subsidiaries in China incur debt on their own behalf in the future, the instruments governing the debt may restrict their
ability to pay dividends or make other payments to us. Accordingly, we may not be able to move our capital easily, which could harm our business.

Restrictions on currency exchange may limit our ability to receive and use our revenue and cash effectively.

Because a substantial portion of our revenue is denominated in RMB, any restrictions on currency exchange may limit our ability to use revenue generated in RMB to fund any business activities we may have
outside China or to make dividend payments in U.S. dollars. Under relevant Chinese rules and regulations, the RMB is currently convertible under the current account, which includes dividends, trade and service-related foreign exchange
transactions, but not under the capital account, which includes foreign direct investment and loans, without the prior approval of the State Administration of Foreign Exchange, or SAFE. Currently, our subsidiaries in China may purchase
foreign exchange for settlement of current account transactions, including the payment of dividends to us, without the approval of SAFE. Although Chinese government regulations now allow greater convertibility of the RMB for current
account transactions, significant restrictions remain. For example, foreign exchange transactions under our primary Chinese subsidiarys capital account, including principal payments in respect of foreign currency-denominated obligations,
remain subject to significant foreign exchange controls and the approval of SAFE. These limitations could affect the ability of our subsidiaries in China to obtain foreign exchange for capital expenditures through debt or equity financing, including
by means of loans or capital contributions from us. We cannot be certain that Chinese regulatory authorities will not impose more stringent restrictions on the convertibility of the RMB, especially with respect to foreign exchange transactions. If
such restrictions are imposed, our ability to adjust our capital structure or engage in foreign exchange transactions may be limited.

##### Table of Contents

In August 2008, SAFE promulgated the Circular on the Relevant Operating Issues Concerning
the Improvement of the Administration of Payment and Settlement of Foreign Currency Capital of Foreign-invested Enterprises, or Circular 142, a notice regulating the conversion by foreign-invested enterprises of foreign currency into RMB by
restricting how the converted RMB may be used. Circular 142 requires that RMB converted from the foreign currency-dominated capital of a FIE may only be used for purposes within the business scope approved by the applicable government authority and
may not be used for equity investments within China unless specifically provided for otherwise. In addition, SAFE strengthened its oversight over the flow and use of RMB funds converted from the foreign currency-dominated capital of a FIE. The use
of such RMB may not be changed without approval from SAFE. As a result of Circular 142, our subsidiaries in China that are considered foreign-invested enterprises may not be able to convert our capital contributions to them into RMB for equity
investments or acquisitions in China.

Uncertainties with respect to Chinas legal system could adversely affect the legal
protection available to us.

Our operations in China are governed by Chinese laws and regulations. Our subsidiaries in
China are generally subject to laws and regulations applicable to foreign investments in China and, in particular, laws applicable to wholly foreign-owned enterprises. Chinas legal system is a civil law system based on written statutes. Unlike
common law systems, it is a legal system where decided legal cases have limited value as precedents. Since 1979, Chinese legislation and regulations have significantly enhanced the protections afforded to various forms of foreign investments in
China. However, China has not developed a fully-integrated legal system, and recently-enacted laws and regulations may not sufficiently cover all aspects of economic activities in China. In particular, because these laws and regulations are
relatively new, the interpretation and enforcement of these laws and regulations involve uncertainties. For example, we may have to resort to administrative and court proceedings to enforce the legal protection under contracts or law. However, since
Chinese administrative and court authorities have significant discretion in interpreting and implementing statutory and contract terms, it may be more difficult to evaluate the outcome of administrative and court proceedings and the level of legal
protection we would receive compared to more developed legal systems. In addition, protections of intellectual property rights and confidentiality in China may not be as effective as in the United States or other countries or regions with more
developed legal systems. Furthermore, the legal system in China is based in part on government policies and internal rules (some of which are not published on a timely basis or at all) that may have a retroactive effect. As a result, we may not be
aware of our violation of these policies and rules until sometime after the violation. In addition, any litigation in China may be protracted and result in substantial costs and diversion of resources and management attention. All the uncertainties
described above could limit the legal protections available to us.

Chinese regulations relating to offshore investment activities by
Chinese residents and employee stock options granted by overseas-listed companies may increase our administrative burden, restrict our overseas and cross-border investment activity or otherwise adversely affect the implementation of our acquisition
strategy. If our stockholders who are Chinese residents, or our Chinese employees who are granted or exercise stock options, fail to make any required registrations or filings under such regulations, we may be unable to distribute profits and may
become subject to liability under Chinese laws.

Chinese foreign exchange regulations require Chinese residents and
corporate entities to register with local branches of SAFE in connection with their direct or indirect offshore investment activities. These regulations apply to our stockholders who are Chinese residents and may apply to any offshore acquisitions
that we make in the future. Pursuant to these foreign exchange regulations, Chinese residents who make, or have previously made, direct or indirect investments in offshore companies, will be required to register those investments. In addition, any
Chinese resident who is a direct or indirect stockholder of an offshore company is required to file or update the registration with the local branch of SAFE, with respect to that offshore company, any material change involving its round-trip
investment, capital variation, such as an increase or decrease in capital, transfer or swap of shares, merger, division, long-term equity or debt investment or creation of any security interest. If any Chinese stockholder fails to make the required
SAFE registration or file or update the registration, subsidiaries in China of that offshore parent company may be prohibited from distributing their profits and the



32



---

##### Table of Contents

proceeds from any reduction in capital, share transfer or liquidation, to their offshore parent company, and the offshore parent company may also be prohibited from injecting additional capital
into their subsidiaries in China. Moreover, failure to comply with the various foreign exchange registration requirements described above could result in liability under Chinese laws for evasion of applicable foreign exchange restrictions. We cannot
provide any assurances that all of our stockholders who are Chinese residents have made or obtained, or will make or obtain, any applicable registrations or approvals required by these foreign exchange regulations. The failure or inability of our
stockholders in China to comply with the required registration procedures may subject us to fines and legal sanctions, restrict our cross-border investment activities, or limit our Chinese subsidiaries ability to distribute dividends or obtain
foreign-exchange-dominated loans. Moreover, because of the uncertainties in the interpretation and implementation of these foreign exchange regulations, we cannot predict how they will affect our business operations or future strategy. For example,
we may be subject to a more stringent review and approval process with respect to our foreign exchange activities, such as remittance of dividends and foreign-currency-denominated borrowings, which may adversely affect our results of operations and
financial condition. In addition, if we decide to acquire a domestic company in China, we cannot assure you that we or the owners of such company, as the case may be, will be able to obtain the necessary approvals or complete the necessary filings
and registrations required by these foreign exchange regulations. This may restrict our ability to implement our acquisition strategy and could adversely affect our business and prospects.

On March 28, 2007, SAFE promulgated the Application Procedure of Foreign Exchange Administration for Domestic Individuals
Participating in Employee Stock Holding Plan or Stock Option Plan of Overseas-Listed Company, or the Stock Option Rule. Under the Stock Option Rule, Chinese residents who are granted stock options by an overseas publicly-listed company are
required, through a Chinese agent or Chinese subsidiary of such overseas publicly-listed company, to register with SAFE and complete certain other procedures. We and our Chinese employees who have been granted stock options are subject to the Stock
Option Rule. We are currently in the process of registering our stock option and appreciation plans with SAFE. If we or our optionees in China fail to comply with these regulations, we or our optionees in China may be subject to fines and legal
sanctions. Several of our employees in China have exercised their stock options prior to our becoming an overseas publicly-listed company. Since there is not yet a clear regulation on how and whether Chinese employees can exercise their stock
options granted by overseas private companies, it is unclear whether such exercises are permissible by Chinese laws and it is uncertain how SAFE or other government authorities will interpret or administer such regulations. Therefore, we cannot
predict how such exercises will affect our business or operations. For example, we may be subject to more stringent review and approval processes with respect to our foreign exchange activities, such as remittance of dividends and
foreign-currency-denominated borrowings, which may affect our results of operations and financial condition.

We may be obligated to
withhold and pay individual income tax in China on behalf of our employees who are subject to individual income tax in China arising from the exercise of stock options. If we fail to withhold or pay such individual income tax in accordance with
applicable Chinese regulations, we may be subject to certain sanctions and other penalties and may become subject to liability under Chinese laws.

The State Administration of Taxation has issued several circulars concerning employee stock options. Under these circulars, our Chinese employees (which could include both employees in China and
expatriate employees subject to individual income tax in China) who exercise stock options will be subject to individual income tax in China. Our subsidiaries in China have obligations to file documents related to employee stock options with
relevant tax authorities and withhold and pay individual income taxes for those employees who exercise their stock options. However, since there is not yet a clear regulation on how and whether Chinese employees can exercise stock options granted by
overseas private companies and how Chinese employers shall withhold and pay individual taxes, the relevant tax authority has verbally advised us that due to the difficulty in determining the fair market value of our shares as a private company, we
did not withhold and pay the individual income tax for the exercises until after we completed our initial public offering in February 2011. Thus, we have not withheld and paid the individual income tax for the option exercises through the date of
our initial public offering. However, we cannot assure you that the Chinese tax authorities will not act otherwise and request us to withhold and pay the individual income tax immediately and impose sanctions on us.

##### Table of Contents

If the Chinese government determines that we failed to obtain approvals of, or registrations with, the
requisite Chinese government with respect to our current and past import and export of technologies, we could be subject to sanctions.

China imposes controls on technology import and export. The term technology import and export is broadly defined to include, without limitation, the transfer or license of patents, software
and know-how, and the provision of services in relation to technology. Depending on the nature of the relevant technology, the import and export of technology to or from China requires either approval by, or registration with, the relevant Chinese
governmental authorities.

If we are found to be, or to have been, in violation of Chinese laws or regulations, the relevant
regulatory authorities have broad discretion in dealing with such violation, including, but not limited to, issuing a warning, levying fines, restricting us from benefiting from these technologies inside or outside of China, confiscating our
earnings generated from the import or export of such technology or even restricting our future export and import of any technology. If the Chinese government determines that our past import and export of technology were inconsistent with, or
insufficient for, the proper operation of our business, we could be subject to similar sanctions. Any of these or similar sanctions could cause significant disruption to our business operations or render us unable to conduct a substantial portion of
our business operations and may adversely affect our business and result of operations.

China regulation of loans and direct investment
by offshore holding companies to China entities may delay or prevent us from using the proceeds we received from our initial public offering to make loans or additional capital contributions to our China subsidiaries.

In utilizing the proceeds we received from our initial public offering, we may make loans or additional capital contributions to our China
subsidiaries. Any loans to our China subsidiaries are subject to China regulations and approvals. For example, any loans to our China subsidiaries to finance their activities cannot exceed statutory limits, must be registered with SAFE, or its local
counterpart, and must be approved by the relevant government authorities. Any capital contributions to our China subsidiaries must be approved by the Ministry of Commerce or its local counterpart. In addition, under Circular 142, our China
subsidiaries, as foreign-invested enterprises, may not be able to convert our capital contributions to them into RMB for equity investments or acquisitions in China.

We cannot assure you that we will be able to obtain these government registrations or approvals on a timely basis, if at all, with respect to our future loans or capital contributions to our China
subsidiaries. If we fail to receive such registrations or approvals, our ability to use the proceeds of our initial public offering and to capitalize our China subsidiaries may be negatively affected, which could materially and adversely affect our
liquidity and ability to fund and expand our business.

Dividends paid to us by our Chinese subsidiaries may be subject to Chinese
withholding tax.

The EIT Law and the implementation regulations provide that a 10% withholding tax may apply to
dividends payable to investors that are non-resident enterprises, to the extent such dividends are derived from sources within China. The comprehensive Double Taxation Arrangement between China and Hong Kong generally reduces the
withholding tax on dividends paid from a Chinese company to a Hong Kong company to 5%. Dividends paid to us by our Chinese subsidiaries will be subject to Chinese withholding tax if, as expected, we are considered a non-resident
enterprise under the EIT Law. If dividends from our Chinese subsidiaries are subject to Chinese withholding tax, our financial condition may be adversely impacted to the extent of such tax.

Our worldwide income may be subject to Chinese tax under the EIT Law.

The EIT Law provides that enterprises established outside of China whose de facto management bodies are located in China are
considered resident enterprises and are generally subject to the uniform 25% enterprise



34

##### Table of Contents

income tax on their worldwide income. Under the implementation regulations for the EIT Law issued by the State Council, a de facto management body is defined as a body that has
material and overall management and control over the manufacturing and business operations, personnel and human resources, finances and treasury, and acquisition and disposition of properties and other assets of an enterprise. If we are deemed to be
a resident enterprise for Chinese tax purposes, we will be subject to Chinese tax on our worldwide income at the 25% uniform tax rate, which could have an impact on our effective tax rate and an adverse effect on our net income (loss), however,
dividends paid to us by our Chinese subsidiaries may not be subject to withholding if we are deemed to be a resident enterprise.

Dividends payable by us to our investors and gains on the sale of our common stock by our foreign investors may be subject to tax under Chinese
law.

Under the EIT Law and implementation regulations issued by the State Council, a 10% withholding tax is applicable
to dividends payable to investors that are non-resident enterprises. Similarly, any gain realized on the transfer of common stock by such investors is also subject to a 10% withholding tax if such gain is regarded as income derived from
sources within China. If we are determined to be a resident enterprise, dividends we pay on our common stock, or the gain you may realize from the transfer of our common stock, would be treated as income derived from sources within
China. If we are required under the EIT Law to withhold tax from dividends payable to investors that are non-resident enterprises, or if a gain realized on the transfer of our common stock is subject to withholding, the value of your
investment in our common stock may be materially and adversely affected.

Because a substantial portion of our business is located in
China, we may have difficulty establishing adequate management, legal and financial controls, which we are required to do in order to comply with Section 404 of the Sarbanes-Oxley Act and securities laws, and which could cause a material
adverse impact on our consolidated financial statements, the trading price of our common stock and our business.

Chinese companies have historically not adopted a western style of management and financial reporting concepts and practices, which
includes strong corporate governance, internal controls and computer, financial and other control systems. Most of our middle and top management staff in China are not educated and trained in the western system, and we may have difficulty hiring new
employees in China with experience and expertise relating to accounting principles generally accepted in the United States and U.S. public-company reporting requirements. As a result of these factors, we may experience difficulty in
establishing management, legal and financial controls, collecting financial data and preparing financial statements, books of account and corporate records and instituting business practices that meet U.S. public-company reporting requirements. We
may, in turn, experience difficulties in implementing and maintaining adequate internal controls as required under Section 404 of the Sarbanes-Oxley Act. This may result in material weaknesses in our internal controls which could impact the
reliability of our consolidated financial statements and prevent us from complying with SEC rules and regulations and the requirements of the Sarbanes-Oxley Act. Any such material weaknesses or lack of compliance with SEC rules and regulations could
result in restatements of our historical consolidated financial statements, cause investors to lose confidence in our reported financial information, have an adverse impact on the trading price of our common stock, adversely affect our ability to
access the capital markets and our ability to recruit personnel, lead to the delisting of our securities from the stock exchange on which they are traded. This could lead to litigation claims, thereby diverting managements attention and
resources, and which may lead to the payment of damages to the extent such claims are not resolved in our favor, lead to regulatory proceedings, which may result in sanctions, monetary or otherwise, and have a material adverse effect on our
reputation and business.

internal control over financial reporting in the future, the accuracy and timing of our financial reporting may be adversely affected.

Our subsidiaries in China are subject to Chinese labor laws and regulations. Recently enacted Chinese
labor laws may increase our operation costs in China.

China Labor Contract Law, effective January 1, 2008,
together with its implementing rules, effective September 18, 2008, provides more protection to Chinese employees. Previously, an employer had discretionary power in deciding the probation period, not to exceed six months. Additionally, the
employment contract could only be terminated for cause. Under the new rules, the probation period varies depending on contract terms and the employment contract can only be terminated during the probation period for cause upon three days notice.
Additionally, an employer may not be able to terminate a contract during the probation period on the grounds of a material change of circumstances or a mass layoff. The new law also has specific provisions on conditions when an employer has to sign
an employment contract with open-ended terms. If an employer fails to enter into an open-ended contract in certain circumstances, the employer must pay the employee twice their monthly wage beginning from the time the employer should have executed
an open-ended contract. Additionally an employer must pay severance for nearly all terminations, including when an employer decides not to renew a fixed-term contract.

On January 1, 2008, the Regulations on Paid Annual Leaves of Staff and Workers also took effect, followed by its implementing measures effective September 18, 2008. These regulations provide
that employees who have worked consecutively for one year or more are entitled to paid annual leave. An employer must guarantee that employees receive the same wage income during the annual leave period as that for the normal working period. Where
an employer cannot arrange annual leave for an employee due to production needs, upon agreement with the employee, the employer must pay daily wages equal to 300% of the employees daily salary for each day of annual leave forfeited by
such employee.

The Shenzhen municipal government, effective December 2010, issued a measure to require all government
agencies, public institutions, and enterprises in Shenzhen to pay a monthly housing fund. The housing fund is designed to enhance the welfare and increase the funds available to Shenzhen employees when buying, building, renovating, or overhauling
owner-occupied houses. Employee and employers are required to make equal contributions to the housing fund, which can range between 5% and 20% and we commenced making these contributions in the fourth quarter of 2010.

From time to time, the Chinese government has implemented requirements to increase the minimum wage for employees in China. These
requirements have resulted in the past, and may result in the future, in higher employee costs for our personnel in China. For example, we expect that the minimum wage in Shenzhen, China will increase by 20% in April 2011. We will be required to
increase wages to comply with these requirements and, potentially, more than the minimum wage adjustment requires, due to market conditions or additional government mandates. If labor costs in China continue to increase, our gross margins and
results of operations may be adversely affected. In addition, our competitive advantage against competitors with personnel costs or manufacturing in traditionally higher cost countries may be diminished. These newly introduced laws and regulations
may materially increase the costs of our operations in China.

The turnover of direct labor in manufacturing industries in China is
high, which could adversely affect our production, shipments, and results of operations.

Employee turnover of direct
labor in the manufacturing sector in China is high and retention of such personnel is a challenge to companies located in or with operations in China. Although direct labor cost does not represent a high proportion of our overall manufacturing
costs, direct labor is required for the manufacture of our products. If our direct labor turnover rates are higher than we expect, or we otherwise fail to adequately manage our direct labor turnover rates, then our results of operations could be
adversely affected.

##### Table of Contents

Adoption of international labor standards may increase our direct labor costs.

International standards of corporate social responsibility include strict requirements on labor work practices and overtime. As global
service providers and their network equipment vendors adopt these standards, we have in the past incurred and may be required in the future to incur additional direct labor costs associated with our compliance with these standards.

If any of our subsidiaries in China becomes the subject of a bankruptcy or liquidation procedures, we may lose the ability to use its assets.

Because a substantial portion of our business and revenue are derived from China, if any of our subsidiaries in China
goes bankrupt and all or part of its assets become subject to liens or rights of third-party creditors, we may be unable to continue some or all of our operations in China. Any delay, interruption or cessation of all or a part of our operations in
China would negatively impact our ability to generate revenue and otherwise adversely affect our business.

We face risks related to
health epidemics and outbreaks of contagious diseases.

Over the past several years, there have been recent reports of
outbreaks of avian flu, SARS and H1N1 swine flu in Asia. Since a large portion of our operations and our customers and suppliers operations are currently based in Asia (mainly China), an outbreak of avian flu, SARS, H1N1 swine flu or
other contagious diseases in Asia or elsewhere, or the perception that such outbreak could occur, and the measures taken by the governments of countries affected, including China, may result in material disruptions in our operations.

Risks related to ownership of our common stock

Our financial results may vary significantly from quarter-to-quarter due to a number of factors, which may lead to volatility in our stock price.

Our quarterly revenue and results of operations have varied in the past and may continue to vary significantly from quarter to quarter.
This variability may lead to volatility in our stock price as research analysts and investors respond to these quarterly fluctuations. These fluctuations are due to numerous factors, including:



| |  |  | fluctuations in demand for our products;
| | - |  | ----------------------------------------



| |  |  | the timing, size and product mix of sales of our products;
| | - |  | ----------------------------------------------------------



| |  |  | changes in our pricing and sales policies or the pricing and sales policies of our competitors;
| | - |  | -----------------------------------------------------------------------------------------------



| |  |  | our ability to design, manufacture and deliver products to our customers in a timely and cost-effective manner and that meet customer requirements;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | quality control or yield problems in our manufacturing operations;
| | - |  | ------------------------------------------------------------------



| |  |  | our ability to timely obtain adequate quantities of the components used in our products;
| | - |  | ----------------------------------------------------------------------------------------



| |  |  | length and variability of the sales cycles of our products;
| | - |  | -----------------------------------------------------------



| |  |  | unanticipated increases in costs or expenses; and
| | - |  | -------------------------------------------------



| |  |  | fluctuations in foreign currency exchange rates.
| | - |  | ------------------------------------------------

The foregoing factors are difficult to forecast, and these, as well as other factors, could materially adversely affect our quarterly and annual results of operations. In addition, a significant amount of
our operating expenses is relatively fixed in nature due to our internal manufacturing, research and development, sales and general administrative efforts. Any failure to adjust spending quickly enough to compensate for a revenue shortfall could
magnify the adverse impact of such revenue shortfall on our results of operations. Moreover, our results of

##### Table of Contents

operations may not meet our announced guidance or the expectations of research analysts or investors, in which case the price of our common stock could decrease significantly. There can be no
assurance that we will be able to successfully address these risks.

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 Annual Report on Form 10-K, 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, 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.

If research analysts do not publish research about our business or if they issue unfavorable commentary or downgrade our common stock, our stock
price and trading volume could decline.

The trading market for our common stock depends in part on the research and
reports that research analysts publish about us and our business. The price of our common stock could decline if one or more research analysts downgrade our stock or if those analysts issue other unfavorable commentary or cease publishing reports
about us or our business. If one or more of the research analysts ceases coverage of our company or fails to publish reports on us regularly, demand for our common stock could decrease, which could cause our stock price or trading volume to decline.

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

As of February 28, 2011, our
executive officers and directors, and entities that are affiliated with them, beneficially own an aggregate of approximately 59% 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, may 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.

Future sales of shares of our common stock by stockholders could depress the price of our common stock.

As of February 28, 2011, we had an aggregate of 24,626,001 shares of common stock outstanding. Of this amount,
8,625,000 shares sold pursuant to the initial public offering completed in February 2011 are currently tradable without restriction. Of the remaining shares:



| |  |  | 800,938 shares will be eligible for sale in May 2011;
| | - |  | -----------------------------------------------------

##### Table of Contents

| |  |  | 15,193,398 shares will be eligible for sale in August 2011 upon the expiration of lock-up agreements entered into with substantially all of our
stockholders in connection with our initial public offering, subject in some cases to volume and other restrictions of Rule 144 and Rule 701 under the Securities Act of 1933, as amended, or the Securities Act; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 6,665 shares will be eligible for sale in the public market from time to time thereafter upon the lapse of our right of repurchase with respect to any
unvested shares.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------

The lock-up agreements expire on July 31, 2011, subject to potential extension in the
event we release earning results or material news or a material event relating to us occurs near the end of the lock-up period. Merrill Lynch, Pierce, Fenner & Smith Incorporated, as a representative of the underwriters, may, in its
discretion and at any time without notice, release all or any portion of the securities subject to lock-up agreements. Merrill Lynch, Pierce, Fenner & Smith Incorporated has agreed not to release any of the lock-up agreements with our
directors and executive officers and substantially all of our stockholders without the prior written consent of Deutsche Bank Securities Inc.

In addition, we have registered 3,211,778 shares of our common stock that have been issued or reserved for future issuance under our stock incentive plans.

Sales of substantial amounts of our common stock in the public market, or the perception that these sales could occur, could cause the
market price of our common stock to decline. These sales could also make it more difficult for us to sell equity or equity-related securities in the future at a time and price that we deem appropriate.

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 loan and security agreement with Comerica Bank restrict our ability to pay dividends. See Dividend policy for more information. 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 initial
public offering will ever exceed the price that you pay.

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 Delaware General Corporate Law 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, 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. See Description of capital stockPreferred stock and Description of capital stockAnti-takeover effects of provisions of our amended and restated certificate of incorporation, our bylaws
and Delaware law.

In
addition, we lease a number of smaller offices in China for warehouse, manufacturing and other functions.



|ITEM 3. | LEGAL PROCEEDINGS
|------- | -----------------

From time to time, we are involved in litigation that we believe is of the type common to companies engaged in our line of business, including commercial disputes and employment issues. As of the date of
this Annual Report on Form 10-K, other than as described below, we are not involved in any pending legal proceedings that we believe could have a material adverse effect on our financial condition, results of operations or cash flows. However, as
described below, a certain pending dispute involves a claim by a third party that our activities infringe their intellectual property rights. This and other types of intellectual property rights claims generally involve the demand by a third party
that we cease the manufacture, use or sale of the allegedly infringing products, processes or technologies and/or pay substantial damages or royalties for past, present and future use of the allegedly infringing intellectual property. Claims that
our products or processes infringe or misappropriate any third-party intellectual property rights (including claims arising through our contractual indemnification of our customers) often involve highly complex, technical issues, the outcome of
which is inherently uncertain. Moreover, from time to time, we may pursue litigation to assert our intellectual property rights. Regardless of the merit or resolution of any such litigation, complex intellectual property litigation is generally
costly and diverts the efforts and attention of our management and technical personnel which could adversely affect our business.

Finisar
Corporation v. Source Photonics, Inc., et al.

On January 5, 2010, Finisar Corporation, or Finisar, filed a complaint
in the United States District Court for the Northern District of California against Source Photonics, Inc., MRV Communications, Inc., Oplink



40

##### Table of Contents

Communications, Inc. and us, or collectively, the co-defendants. In the complaint, Finisar alleged infringement of certain of its U.S. patents arising from the co-defendants respective
manufacture, importation, use, sale or offer to sell certain optical transceiver products in the United States. Finisar sought to recover unspecified damages, up to treble the amount of actual damages, together with attorneys fees, interest
and costs. Finisar alleged that at least some of the patents asserted are a part of certain digital diagnostic standards for optoelectronics transceivers, and, therefore, are being utilized in such digital diagnostic standards. On March 23,
2010, we filed an answer to the complaint and counterclaims, asserting two claims of patent infringement and additional claims asserting that Finisar has violated state and federal competition laws and violated its obligations to license on
reasonable and non-discriminatory terms. On May 5, 2010, the court dismissed without prejudice all co-defendants (including us) except Source Photonics, Inc., on grounds that such claims should have been asserted in four separate lawsuits, one
against each co-defendant. This dismissal without prejudice does not prevent Finisar from bringing a new similar lawsuit against us. We and Finisar had agreed to a 90 day tolling of our respective claims and not to refile any claims against each
other until one or more specified events occur resulting in the partial or complete resolution of the litigation between Source Photonics and Finisar. On September 10, 2010, Source Photonics and Finisar settled their lawsuit, commencing the
tolling period, which expired in early December 2010.

On January 18, 2011, we and Finisar again agreed to toll our
respective claims and not to refile the originally asserted claims against each other until at least 90 days after one or more specified events occur resulting in the partial or complete resolution of litigation involving the same Finisar patents
between Oplink Communications, Inc. and Finisar. At that time, Finisar will be permitted to bring a new lawsuit against us if they choose to do so. If we are unsuccessful in our defense of the Finisar patent infringement claims, a license to use the
allegedly infringing technology may not be available to us at all, and if it is, it may not be available on commercially reasonable terms and therefore may limit or preclude us from competing in the market for optical transceivers in the United
States, which may have a material adverse effect on our results of operations and financial condition, and otherwise materially harm our business.

Although we believe that we would have meritorious defenses to the infringement allegations and intend to defend any new similar lawsuit vigorously, there can be no assurance that we will be successful in
our defense. Even if we are successful, we may incur substantial legal fees and other costs in defending the lawsuit. Further, a new lawsuit, if brought, would be likely to divert the efforts and attention of our management and technical personnel,
which could harm our business.

On February 2, 2011, the effective date of our Registration Statement on Form S-1 (File No. 333-166096), our common stock began
to trade on the New York Stock Exchange under the symbol NPTN. As of February 28, 2011, the closing price of our common stock as reported on the New York Stock Exchange was $18.35 and there were approximately 301 holders of record
of our common stock. We have not paid cash dividends on our common stock since our inception, and we do not anticipate paying any in the foreseeable future. Any future determination as to the declaration and payment of dividends, if any, will be at
the discretion of our board of directors and will depend on then existing conditions, including our financial condition, operating results, contractual restrictions, capital requirements, business prospects and other factors our board of directors
may deem relevant.

For equity compensation plan information refer to Item 12 of this Annual Report on Form 10-K.

In January 2010, we issued 2,401 shares of Series X preferred stock for $2,500.00 per share and received cash proceeds of
$6.0 million. Proceeds from the sale of Series X preferred stock were utilized for working capital, continued expansion of our existing business and general corporate purposes. Shares of Series X preferred stock were convertible into shares of our
common stock pursuant to our Amended and Restated Certificate of Incorporation. In connection with the closing of our initial public offering in February 2011, all of the shares of Series X preferred stock outstanding automatically converted into
shares of common stock on a 400-for-1 basis. The shares of Series X preferred stock were sold to certain of our existing investors, and no underwriters were involved in this transaction. In connection with the issuance of Series X preferred, we
filed a Form D, Notice of Exempt Offering of Securities with the Securities and Exchange Commission pursuant to Rule 506 of Section 4(2) of the Securities Act of 1933, as amended, and in the States of California, Colorado, Georgia, Illinois and
Virginia. For further information, see Note 10 of Item 8, Notes to Consolidated Financial Statements.

On
February 2, 2011, our registration statement on Form S-1 (File No. 333-166096) was declared effective for our initial public offering, pursuant to which we registered the offering and sale of 8,625,000 shares of common stock,
including the full underwriters over-allotment option, at a public offering price of $11.00 per share. Merrill Lynch, Pierce, Fenner & Smith Incorporated and Deutsche Bank Securities Inc. acted as the managing underwriters for our
initial public offering. The offering was completed February 7, 2011. As a result of our initial public offering, we received net proceeds of $88.2 million before offering expenses. None of such payments were a direct or indirect payment
to any of our directors or officers or their associates, to persons owning ten percent or more of our common stock or any of our other affiliates.

There has been no material change in the planned use of proceeds from our initial public offering as described in our final prospectus filed with the SEC pursuant to Rule 424(b).

acquired the remaining 0.4% of outstanding shares. Also in 2005, we invested in 7.7% of the outstanding shares of BeamExpress, Inc. and, in 2006, we acquired BeamExpress, Inc. by purchasing the remaining shares. In 2006, we acquired Optun, Inc.,
Lightconnect, Inc. and the assets and liabilities of Paxera Corporation. These acquisitions were accounted for using the purchase method of accounting. Consideration was allocated to the assets acquired and liabilities assumed based on their fair
values, including intangible assets and in-process research and development, and the residual was recorded to goodwill. In-process research and development was expensed at the date of acquisition and the intangible assets are being amortized in cost
of goods sold and in operating expenses

|(3) | In 2007, we recorded asset impairment charges relating to goodwill of $5.9 million and intangible assets of $0.2 million, both relating to our acquisition of
BeamExpress Inc. in 2006. In 2008, we recorded asset impairment charges relating to intangible assets of $3.3 million and property and equipment of $0.7 million, both triggered by our decision to discontinue development of a product
relating to our acquisition of Paxera Corporation in 2006. In 2009, we entered into an agreement to sell our ownership interest in Shenzhen Archcom Technology Co., Ltd, or Archcom, for less than our share of the net assets of Archcom and, as a
result, we recognized an impairment charge of $0.8 million. In 2009, we also recorded an asset impairment charge of $0.4 million resulting from the write-off of machinery and equipment no longer in use. For further information, see Note 5 of Notes
to Consolidated Financial Statements.

consolidated financial statements and the accompanying notes. The following discussion contains forward-looking statements that involve risks and uncertainties, such as statements of our plans, objectives, expectations and intentions. Our actual
results could differ materially from those discussed in the forward-looking statements. Please also see the cautionary language at the beginning of Part I of this Annual Report on Form 10-K regarding forward-looking statements. Factors that could
cause or contribute to such differences include, but are not limited to, those discussed in Risk Factors.

Business
overview

We are a leading designer and manufacturer of PIC-based modules and subsystems for bandwidth-intensive,
high-speed communications networks.

Our products are designed to enable high-speed transmission rates and efficient
allocation of bandwidth over optical networks with high quality and low costs. Our PIC technology utilizes proprietary design elements that provide optical functionality on a silicon chip. PIC devices can integrate many more functional elements than
discretely packaged components, enabling increased functionality in a small form factor while reducing packaging and interconnection costs. In addition, the cost advantages of PIC-based components are similar to the economics of semiconductor wafer
mass manufacturing, where the marginal cost of producing an incremental chip is much less than that of a discrete component.

We have research and development and wafer fabrication facilities in San Jose, California which coordinate with our research and
development and manufacturing facilities in Shenzhen, China. We utilize proprietary design tools and design-for-manufacturing techniques to align our design process with our precision nanoscale, vertically integrated manufacturing and testing
capabilities. We sell our products to the leading network equipment vendors globally, including ADVA AG Optical Networking Ltd., Alcatel-Lucent SA, Ciena Corporation (including its recent acquisition of Nortels Metro Ethernet Networks
business), Cisco Systems, Inc., FiberHome Technologies Group, ECI Telecom Ltd., Telefonaktiebolaget LM Ericsson, Fujitsu Limited, Harmonic, Inc., Huawei Technologies Co., Ltd., Mitsubishi Electric Corporation, NEC Corporation, Nokia Siemens Networks
B.V. and ZTE Corporation. We refer to these companies as our Tier 1 customers.

We operate a sales model that focuses on
direct alignment with our customers through coordination of our sales, product engineering and manufacturing teams. Our sales and marketing organizations support our strategy of increasing product penetration with our Tier 1 customers while also
serving our broader customer base. We use a direct sales force in the United States, China, Canada, Israel, Japan, Russia and the European Union. These individuals work with our product engineers, and product marketing and sales operations
teams, in an integrated approach to address our customers current and future needs. We also engage independent commissioned representatives and distributors worldwide to extend our global reach.

We changed our name to NeoPhotonics Corporation in 2002 after having been incorporated as NanoGram Corporation in October 1996 in the
State of Delaware. During 2002 and 2003, we spun out two new companies, NanoGram Devices Corporation, a medical device battery company, and NanoGram Corporation, a nanomaterials applications company. NanoGram Devices was subsequently acquired by
Greatbatch Inc. NanoGram Corporation was acquired by Teijin Limited in July 2010. In November 2003, we filed a petition for relief under Chapter 11 of the federal bankruptcy laws in the United States Bankruptcy Court for the Northern District of
California. Our plan of reorganization was substantially consummated in March 2004, at which point we emerged from bankruptcy. In addition, we have completed several acquisitions as follows:

| |  |  | In February 2008, we acquired certain assets and intellectual property from Mitsubishi Electric Corporation relating to the manufacture of high-speed
transceivers.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------

The amortization of intangible assets relative to these acquisitions is expected to be
$0.8 million, $0.3 million and $0.1 million for the years ending December 31, 2011, 2012 and 2013, respectively, and will continue to decline until fully amortized.

In February 2011, we completed our initial public offering of 8,625,000 shares of common stock, including the full underwriters over-allotment option, at a public offering price of $11.00 per
share. Our initial public offering generated net proceeds of $88.2 million before offering expenses. In connection with the closing of the initial public offering, all of the shares of our Series 1, Series 2 and Series 3 preferred stock then
outstanding automatically converted into 6,639,513 shares of common stock on a 1-for-1 basis and all of the shares of our Series X preferred stock then outstanding automatically converted into 7,398,976 shares of common stock on a 400-for-1 basis.

Critical accounting policies and estimates

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. These
principles require us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, expenses and cash flow, and related disclosure of contingent assets and liabilities. Our estimates include those related to
revenue recognition, stock-based compensation expense, impairment analysis of goodwill and long-lived assets, valuation of inventory, warranty liabilities and accounting for income taxes. We base our estimates on historical experience and on various
other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates. To the extent that there are material differences between these estimates and our actual results, our future financial
statements will be affected.

We believe that of our significant accounting policies, which are described in Note 2 of
Notes to Consolidated Financial Statements, the following accounting policies involve a greater degree of judgment and complexity. Accordingly, we believe these are the most critical to fully understand and evaluate our financial condition and
results of operations.

Revenue recognition

We recognize revenue from the sale of our products provided that persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable and collectability is reasonably
assured. Contracts and/or customer purchase orders are used to determine the existence of an arrangement. Shipping documents and customer acceptance, when applicable, are used to verify delivery. We assess whether the fee is fixed or determinable
based on the payment terms associated with the transaction and whether the sales price is subject to refund or adjustment. We assess collectability based primarily on the creditworthiness of the customer as determined by credit checks and the
customers payment history.

##### Table of Contents

Revenue is recognized when the product is shipped and title has transferred to the buyer. We
bear all costs and risks of loss or damage to the goods up to that point. On most orders, our terms of sale provide that title passes to the buyer upon shipment by us. In certain cases, our terms of sale may provide that title passes to the buyer
upon delivery of the goods to the buyer. We determine payments made to third-party sales representatives are appropriately recorded to sales and marketing expense and not a reduction of revenue as the sales agent services they provide have an
identifiable benefit and are made at similar rates of other sales agent service providers. Shipping and handling costs are included in the cost of goods sold. We present revenue net of sales taxes and any similar assessments.

We recognize revenue on sales to distributors, using the sell in method (i.e., when product is sold to the distributor) at
the time of shipment or delivery, as our distributors do not have extended rights of return or subsequent price discounts or price protections.

Stock-based compensation expense

Our stock-based compensation expense was recorded as follows:

Effective January 1, 2006, we adopted new authoritative accounting guidance for stock-based
compensation expense, which requires enterprises to measure the cost of employee services received in exchange for an award of equity instruments, including stock options, based on the grant date fair value of the award. We adopted the new guidance
using the prospective transition method. Under this transition method, beginning January 1, 2006, employee stock-based compensation expense includes: (1) compensation cost for all stock-based awards granted prior to, but not yet vested as
of December 31, 2005, based on the intrinsic value method and (2) compensation cost for all stock-based awards granted or modified subsequent to December 31, 2005, based on the grant date fair value estimated in accordance with the
new guidance.

Our determination of the fair value of stock-based payment awards on the measurement date utilizes the
Black-Scholes option pricing model, and is impacted by our common stock price as well as changes in assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to, expected common stock
price volatility over the term of the option awards, projected employee option exercise behaviors (expected period between stock option vesting date and stock option exercise date), risk-free interest rates and expected dividends.

The fair value is recognized over the period during which an employee is required to provide services in exchange for the award, known as
the requisite service period (usually the vesting period) on a straight-line basis. Stock-based compensation expense includes the impact of estimated forfeitures. We estimate future forfeitures at the date of grant and revise the estimates, if
necessary, in subsequent periods if actual forfeitures differ from those estimates.

The Black-Scholes pricing model was
developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable, characteristics not present in our option grants. Existing valuation models, including the Black-Scholes model, may not
provide reliable measures of the fair value of our

stock-based awards. Consequently, there is a risk that our estimates of the fair value of our stock-based awards on the grant dates may bear little resemblance to the actual values realized upon
exercise. Stock options may expire or otherwise result in zero intrinsic value as compared to the fair values originally estimated on the grant date and reported in our consolidated financial statements. Alternatively, value may be realized from
these instruments that are significantly higher than the fair values originally estimated on the grant date and reported in our consolidated financial statements.

For the years ended December 31, 2010, 2009 and 2008, we calculated the fair value of stock options granted to employees using the Black-Scholes pricing model with the following assumptions:



|                                       |  |                          |  |               |  |              
|-------------------------------------- |  | ------------------------ |  | ------------- |  | -------------
|                                       |  | Years ended December 31,
|                                       |  | 2010                     |  | 2009          |  | 2008         
|Weighted-average expected term (years) |  | 6.59                     |  | 6.00          |  | 5.84         
|Weighted-average volatility            |  | 73%                      |  | 79%           |  | 77%          
|Risk-free interest rate                |  | 2.51%  3.19%            |  | 2.15%  3.12% |  | 2.81%  3.45%
|Expected dividends                     |  | 0%                       |  | 0%            |  | 0%           

In addition to the
assumptions used to calculate the fair value of our options, we are required to estimate the expected forfeiture rate of all stock-based awards and only recognize expense for those awards we expect to vest. Accordingly, the stock-based compensation
expense recognized in our consolidated statement of operations for the year ended December 31, 2010 has been reduced for estimated forfeitures. If we were to change our estimate of forfeiture rates, the amount of stock-based compensation
expense could differ, materially under certain circumstances, from the amount recognized in our consolidated financial statements. For example, if we had decreased our estimate of expected forfeitures by 50%, our stock-based compensation expense for
the year ended December 31, 2010, net of expected forfeitures, would have increased by $263,000. This decrease in our estimate of expected forfeitures would increase the amount of expense for all unvested awards that have not yet been
recognized by $430,000 as of December 31, 2010, which would be amortized over a weighted-average period of 3.0 years. In addition, if our stock-based compensation expense increases in the future, the impact of a change in the estimated
forfeiture rate could be more significant.

As of December 31, 2010, we had 301,594 stock appreciation units issued and
outstanding, respectively. These stock appreciation units are not exercisable by any recipient until the earliest to occur of the following: (i) the expiration of the period of time agreed to between our underwriters and certain of our
stockholders selected by the underwriters in connection with a public offering of the stock, or (ii) upon the consummation of a change in control, which means a sale of all or substantially all of our assets, or a merger, consolidation or other
capital reorganization or business combination transaction with or into another corporation or entity. Because neither of these events has occurred and therefore recipients are not able to exercise their units, no compensation expense has been
recognized to date relative to these awards. Upon the occurrence of either of the two events, we would recognize compensation expense and corresponding liability equal to the number of vested and outstanding stock appreciation units multiplied by
the fair value, calculated using the Black-Scholes option pricing model, on that date.

Stock-based compensation expense
subsequent to December 31, 2010 will include an estimate of a catch-up expense for stock appreciation units previously granted to certain employees as well as the ongoing expense relating to the portion of these awards vesting after our initial
public offering in February 2011. Prior to our initial public offering, no expense was recognized for these awards given their contingent nature. The expense will be calculated using the Black-Scholes option pricing model and will include the value
of our common stock, which could vary significantly.

In addition, we plan to issue stock purchase rights under our 2010
Employee Stock Purchase Plan, and we may also issue additional stock-based equity awards under our 2010 Equity Incentive Plan, which will result in additional stock-based compensation expense.

Goodwill and long-lived assets

Goodwill is evaluated, at a minimum, on an annual basis and whenever events and changes in circumstances suggest that the carrying amount
may not be recoverable. Our annual goodwill impairment testing is performed on December 31 of each year. Goodwill is reviewed for impairment utilizing a two-step process. First, impairment of goodwill is tested at the reporting unit level by
comparing the reporting units carrying amount, including goodwill, to the fair value of the reporting unit. The fair value of the reporting unit is estimated using a discounted cash flow approach. If the carrying amount of the reporting unit
exceeds its fair value, a second step is performed to measure the amount of impairment loss, if any. In step two, the implied fair value of goodwill is calculated as the excess of the fair value of a reporting unit over the fair values assigned to
its assets and liabilities. If the implied fair value of goodwill is less than the carrying value of the reporting units goodwill, the difference is recognized as an impairment loss. We did not recognize any goodwill impairment charges during
the years ended December 31, 2010, 2009 or 2008.

Depreciation and amortization of the intangible assets and other
long-lived assets is provided using the straight-line method over their respective estimated useful lives, reflecting the pattern of economic benefits associated with these assets. Changes in circumstances such as technological advances, changes to
our business model, or changes in our capital strategy could cause the actual useful lives of intangible assets or other long-lived assets to differ from initial estimates. In those cases where we determine that the useful life of an asset
should be revised, we depreciate the remaining net book value over the new estimated useful life.

These assets are evaluated
for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable based on their future cash flows. The estimated future cash flows are based upon, among other things, assumptions
about expected future operating performance and may differ from actual cash flows. The assets evaluated for impairment are grouped, based on our judgment, with other assets at the lowest level for which identifiable cash flows are largely
independent of the cash flows of other groups of assets and liabilities. If the sum of the projected undiscounted cash flows (excluding interest) is less than the carrying value of the assets, the assets will be written down to the estimated fair
value. We did not record any asset impairment charges related to finite-lived assets during the year ended December 31, 2010. During the years ended December 31, 2009 and 2008, we recorded asset impairment charges of $1.2 million and
$4.0 million, respectively.

Valuation of inventories

Inventories are recorded at the lower of cost (using the first-in, first-out method) or market, after we give appropriate consideration to obsolescence and inventories in excess of anticipated future
demand. In assessing the ultimate recoverability of inventories, we are required to make estimates regarding future customer demand, the timing of new product introductions, economic trends and market conditions. If the actual product demand is
significantly lower than forecasted, we could be required to record additional inventory write-downs which would be charged to cost of goods sold. Any write-downs would have an adverse impact on our gross margin. During the years ended
December 31, 2010, 2009 and 2008, we recorded excess and obsolete inventory charges of $1.2 million, $1.1 million and $0.0 million, respectively.

Warranty liabilities

We provide warranties to cover defects in
workmanship, materials and manufacturing of our products for a period of one to two years to meet stated functionality specifications. From time to time, we have agreed, and may agree, to warranty provisions providing for extended terms or with a
greater scope. Products are tested against specified functionality requirements prior to delivery, but we nevertheless from time to time experience claims under our warranty guarantees. We accrue for estimated warranty costs under those guarantees
based upon historical experience, and for specific items at the time their existence is known and the amounts are determinable. A provision for estimated future costs related to warranty activities is charged to cost of goods sold based upon
historical product failure rates and historical costs incurred in correcting product failures. If we

experience an increase in warranty claims compared with our historical experience, or if the cost of servicing warranty claims is greater than expected, our gross margin and profitability would
be adversely affected. During the years ended December 31, 2010, 2009 and 2008, we recorded warranty expense of $0.4 million, $0.4 million and $0.5 million, respectively.

Accounting for income taxes

We record income taxes using the asset and
liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in our consolidated financial statements or tax returns. In estimating future tax
consequences, generally all expected future events, other than enactments or changes in tax law or rates, are considered. Valuation allowances are provided when necessary to reduce deferred tax assets to the amount expected to be realized.

We operate in various tax jurisdictions and are subject to audit by various tax authorities. We provide for tax contingencies
whenever it is deemed probable that a tax asset has been impaired or a tax liability has been incurred for events such as tax claims or changes in tax laws. Tax contingencies are based upon their technical merits, relevant tax law and the specific
facts and circumstances as of each reporting period. Changes in facts and circumstances could result in material changes to the amounts recorded for such tax contingencies.

Tax effects of a position are recognized only if it is more likely than not to be sustained based solely on its technical merits as of the reporting date. At December 31, 2010, we had
$5.1 million of unrecognized tax benefits, $169,000 of which would affect our effective tax rate if recognized.

As part of
the process of preparing our consolidated financial statements, we are required to estimate our taxes in each of the jurisdictions in which we operate. We estimate actual current tax exposure together with assessing temporary differences resulting
from differing treatment of items, such as accruals and allowances not currently deductible for tax purposes. These differences result in deferred tax assets.

At December 31, 2010, we had total net deferred tax assets of $56.9 million, primarily comprised of U.S. federal and state NOL carryforwards, and a related valuation allowance of $56.4 million,
primarily against our U.S. net deferred tax assets, as we believe that sufficient uncertainty exists regarding the realizability of these deferred tax assets. Our net deferred tax assets consist primarily of NOL carryforwards generated in the United
States. Realizability of deferred tax assets is deemed appropriate when realization of such assets is more likely than not. Based upon the weight of available evidence, which includes our historical operating performance and the recorded U.S.
cumulative net losses, we have provided a full valuation allowance against our U.S. deferred tax assets. We intend to maintain valuation allowances until sufficient evidence exists to support the reversal of the valuation allowances. Under
certain conditions related to our future profitability and other business factors, we believe it is possible our results will yield sufficient positive evidence to support the conclusion that it is more likely than not that we will realize the tax
benefit of our NOL carryforwards. If that is the case, subject to review of other qualitative factors and uncertainties, we would reverse the remaining deferred tax asset valuation allowance as a reduction of tax expense. For the periods following
the recognition of this tax benefit and to the extent we are profitable, we will record a tax provision for which the actual payment may be offset against our accumulated NOL carryforwards. However, our tax rate may significantly increase in future
periods.

We make estimates and judgments about our future taxable income that are based on assumptions that are consistent
with our plans and estimates. Should the actual amounts differ from our estimates, the amount of our valuation allowance could be materially impacted. Any adjustment to the deferred tax asset valuation allowance would be recorded in the consolidated
statement of operations in the period that the adjustment is determined to be required.

We pay withholding taxes on royalty
income from foreign sources. In 2010, these payments were offset by a refund from a favorable tax ruling in China and resulted in net impact of zero to our income tax expense. Although there is a U.S. foreign tax credit for foreign income taxes
paid, we do not record a benefit from these foreign tax credits, due to our full valuation allowance on our U.S. deferred tax assets.

Results of operations

Revenue

We sell substantially all of our products to original equipment
manufacturers, or OEMs. Revenue is recognized upon delivery of our product to the OEM. We price our products based on market and competitive conditions and may periodically reduce the price of our products as market and competitive conditions change
and as manufacturing costs are reduced. Our sales transactions to customers are denominated primarily in RMB or U.S. dollars. For the year ended December 31, 2010, 58% of our sales were derived from our China-based subsidiaries, the majority of
which were denominated in RMB. Revenue is driven by the volume of shipments and may be impacted by pricing pressures. We have generated most of our revenue from a limited number of customers. Given the high concentration of network equipment vendors
in our industry, our top ten customers represented 89%, 83% and 71% of our revenue in 2010, 2009 and 2008, respectively.

Total revenue
increased by $29.1 million in 2010 compared to 2009, representing a 19% increase. The increase in revenue was primarily attributable to an increase in demand for our speed and agility products, as customers began to deploy more sophisticated product
offerings, plus additional design wins and overall market expansion. Although sales increased on a global basis, the increase was primarily realized in China and the United States.

Total revenue increased by $21.1 million in 2009 compared to 2008, representing a 16% increase. The increase in revenue was primarily
attributable to a $33.5 million increase in revenue from our customers in China. The increase in revenue from customers in China was primarily due to increased demand for our speed, agility and access products resulting from the 3G wireless
buildout, partially relating to the economic stimulus program in China, as well as our launch of new products in 2009. The increase in revenue from customers in China was partially offset by lower revenue from other regions of the world, primarily
due to a decrease in revenue in the United States and Japan of $7.9 million from 2008 to 2009. The lower demand in the United States and Japan was primarily driven by lower capital spending by service providers given recessionary economic
conditions in 2009.

We expect that our revenue for 2011 will be higher than our revenue for 2010. We also expect that a
significant portion of our revenue will continue to be derived from a limited number of customers, as a result of growth in purchases by our key China, U.S. and European customers. We expect a significant portion of our sales to be denominated in
foreign currencies in the future, and therefore may be effected by changes in foreign exchange rates.

Cost of goods sold and gross margin

Our cost of goods sold consists primarily of the cost to produce wafers and to manufacture and test our products. We have
a global set of suppliers to help balance considerations related to product availability, quality and cost. Components of our cost of goods sold are denominated primarily in RMB. Our manufacturing process extends from wafer fabrication through final
module and subsystem assembly and test. The cost of our manufacturing, assembly and test processes includes the cost of personnel and the cost of our manufacturing equipment and facilities. Our cost of goods sold is impacted by manufacturing
variances such as assembly and test yields and production volume. We typically experience lower yields and higher associated costs on new products. In general, our cost of goods sold associated with a particular product declines over time as a
result of decreases in wafer costs associated with the increase in the volume of wafers produced, as well as yield improvements and assembly and test enhancements. Additionally, our cost of goods sold includes reserves for excess and obsolete
inventory, royalty payments, amortization of certain purchased intangible assets, warranty, shipping and allocated facilities costs.

Gross profit as a percentage of total revenue, or gross margin, has been and is expected to
continue to be affected by a variety of factors, including the introduction of new products, production volume, production volume compared to sales over time, the mix of products sold, changes in the cost and volumes of materials purchased from our
suppliers, changes in labor costs, changes in overhead costs or requirements, any reserves for excess and obsolete inventories and changes in the average selling prices of our products. Our newer and more advanced products typically have higher
average selling prices and higher gross margins. Average selling prices by product typically decline as a result of periodic negotiations with our customers and competitive pressures. We strive to increase our gross margin as we seek to manage the
costs of our supply chain and increase productivity in our manufacturing processes.

Cost of goods sold
increased by $13.6 million in 2010 compared to 2009, representing a 12% increase. Cost of goods sold increased primarily from higher sales volumes and additional direct labor and overhead costs, offset by lower material costs and improved
manufacturing utilization in 2010, and a decrease in amortization of purchased intangible assets, as these assets became fully amortized. Gross margin was 30% for 2010, compared to 26% for 2009. The improvement in gross margin primarily resulted
from the increase in sales of our higher-margin agility products in 2010, combined with higher cost leveraging and lower material costs resulting from manufacturing cost reductions.

Cost of goods sold increased by $5.1 million in 2009 compared to 2008, representing a 5% increase. Cost of goods sold increased primarily
due to an increase in sales volumes and higher sales of our higher cost PIC products, offset by efficiencies obtained in the manufacturing process, including higher wafer yields due to design improvements, reduced testing needed for more mature
product offerings and improved manufacturing utilization. In addition, expense related to excess and obsolete inventories increased by $1.1 million in 2009 compared to 2008, primarily as a result of integrating our cable television portfolio during
2009. Similarly, the improvement in gross margin is primarily attributable to these impacts.

We expect that our gross margins
are likely to continue to fluctuate as our revenues change over time due to a number of factors, including those mentioned above. In addition, we periodically negotiate pricing with certain customers which can cause our gross margins to fluctuate
particularly in the quarter in which the negotiations occurred. Also, effective December 2010, our China subsidiaries incurred an additional 5% increase in payroll taxes in accordance with the new housing fund requirement issued by Shenzhen
municipal government. Subsequent to our initial public offering in February 2011, the stock-based compensation expense estimate will include an estimate of a catch-up expense for stock appreciation units previously granted to certain employees as
well as the ongoing expense relating to the portion of these awards vesting after our initial public offering in February 2011. This expense will be based in part on our stock price at the relevant period end and thus can vary materially from
estimates. Due to the fact that the compensation costs for many of our China-based employees are included in cost of goods sold, the added housing fund payroll tax and higher stock-based compensation expense as a result of vesting of stock
appreciation rights is expected to adversely affect gross margin in future periods.

Operating expenses

Our operating expenses consist of research and development, sales and marketing, general and administrative, amortization of purchased
intangible assets, asset impairment charges and restructuring charges.

Personnel costs are the most significant component of operating expenses and consist of costs such as salaries, benefits, bonuses, stock-based compensation and, with regard to sales and marketing
expense, sales commissions. Although our operating expenses are denominated primarily in RMB and U.S. dollars, most are denominated in U.S. dollars.

Research and development

Research and development expense consists of personnel costs, including stock-based compensation, for our research and development personnel, and product development costs, including engineering services,
development software and hardware tools, depreciation of capital equipment and facility costs. We record all research and development expense as incurred.

Research and development expense increased by $4.3 million in 2010 compared to 2009, representing a 25% increase. This increase was primarily due to a $2.5 million increase in additional payroll and
employee-related cost in conjunction with increased number of research and development professionals in 2010 and a $2.1 million increase in material usage, project management and design services, and prototype expenses in 2010 as we invested in
additional resources to support future anticipated demand, partially offset by a $0.3 million decrease in depreciation as part of our assets were fully depreciated and new assets were placed into service later in 2010.

Research and development expense decreased by $4.2 million in 2009 compared to 2008, representing a 20% decrease. This was primarily due
to several factors, such as strategic reductions in spending, including a $2.0 million reduction in employee costs. This reduction in employee costs resulted from our reduction in workforce implemented at the end of 2008. In addition, the decrease
was due to a reduction in development and prototype expenses of $1.3 million, redeployment of resources from research and development to manufacturing of $0.5 million and lower depreciation charges of $0.4 million during 2009.

We expect research and development expense to increase as we enhance and expand our product offerings and higher stock-based compensation
expense as a result of vesting and remeasurement of stock appreciation rights. As a percentage of total revenues, our research and development expense may vary as our revenue changes over time.

Sales and marketing

Sales and marketing expense consists primarily of personnel costs, including stock-based compensation and sales commissions, costs related
to sales and marketing programs and services and facility costs.

Sales and marketing expense increased by $0.6 million in
2010 compared to 2009, representing a 6% increase. The increase was primarily due to a $1.0 million increase in employee-related costs and sales commissions, partially offset by a $0.3 million decrease in bad debt expense as a result of improved
collections.

---

##### Table of Contents

Sales and marketing expense decreased by $0.8 million in 2009 compared to 2008, representing
an 8% decrease. This decrease was primarily due to $0.6 million in lower external sales commissions expense and a $0.3 million reduction in employee costs resulting from our reduction in workforce implemented at the end of 2008, partially offset by
an increase in bad debt expense of $0.2 million due to higher defaults of regional foreign cable TV customers in 2009.

We
expect sales and marketing expense to increase as we expand our marketing activities, increase the number of sales and marketing professionals and incur higher stock-based compensation expense and employee-related costs accordingly. As a percentage
of total revenues, our sales and marketing expense may vary as our revenue changes over time.

General and administrative

General and administrative expense consists primarily of personnel costs, including stock-based compensation, for our finance, human
resources and information technology personnel and certain executive officers, as well as professional services costs related to accounting, tax, banking, legal and information technology services, depreciation of capital equipment and facility
costs.

General and administrative expense increased by $1.5 million in 2010 compared to 2009, representing a 10% increase.
This increase was primarily due to increases in legal costs of $1.0 million, personnel costs of $0.4 million, and increases in accounting and tax related costs of $0.5 million, partially offset by lower facilities-related costs of $0.2 million.

General and administrative expense increased by $0.9 million in 2009 compared to 2008, representing a 6% increase. This was
primarily due to an increase in accounting, consulting and advisory costs of $0.4 million and an increase in employee expenses of $0.3 million, due to an increase in incentive-based compensation expense, partially offset by reduced salary-related
expense resulting from our reduction in workforce implemented at the end of 2008.

We expect general and administrative
expense to increase in the short term, as we develop infrastructure necessary to operate as a public company, including increased accounting and legal fees, costs to comply with the Sarbanes-Oxley Act and the rules and regulations applicable to
companies listed on a national stock exchange, as well as investor relations expense and higher insurance premiums. As a percentage of total revenue, our general and administrative expense may vary as our revenue changes over time.

Amortization of purchased intangible assets

We completed a series of business acquisitions in 2005 and 2006, which included the acquisition of intangible assets. These intangible assets are being amortized over their estimated useful lives.

Amortization of purchased intangible assets remained flat in 2010 compared to 2009, as we continue to amortize intangible
assets associated with business acquisitions made prior to 2007.

Amortization of purchased intangible assets decreased by
$0.5 million in 2009 compared to 2008 due to the impairment of intangible assets recognized in 2008 as a result of our decision to discontinue development of a product relating to our acquisition of Paxera Corporation. The impairment resulted in
lower amortization of purchased intangible assets in 2009.

We expect amortization of purchased intangible assets to decrease
as some of our purchased intangible assets were fully amortized in 2010.

Asset impairment charges

We record asset impairment charges when it is determined that the carrying value of our assets is not recoverable.

##### Table of Contents

We did not incur any asset impairment charges in 2010 compared to $1.2 million in 2009 and
$4.0 million in 2008.

In 2009, we entered into an agreement to sell our 55% ownership interest in Shenzhen Archcom Technology
Co., Ltd., or Archcom, for $1.1 million, which was less than our share of the value in the net assets of Archcom. This transaction was completed as of March 31, 2010. As a result, we recognized an impairment charge of $0.8 million in the year
ended December 31, 2009, of which $0.2 million was related to tangible fixed assets and the remaining $0.6 million was recorded as an accrual for the expected loss on sale. In addition, in 2009, we recorded an impairment charge of $0.4 million
resulting from the write-off of machinery and equipment no longer in use.

In 2008, we discontinued the development of a
tunable laser product based on recognized operating losses and the projection of future losses relative to that product. As a result of the discontinuance, we concluded that certain asset groups associated with the product were impaired and an asset
impairment charge of $4.0 million was recognized in the year ended December 31, 2008, of which $3.3 million was related to purchased intangible assets and $0.7 million was related to tangible fixed assets.

Asset impairment charges are based on individual facts and circumstances and are not otherwise considered a recurring expense. Although
we have recognized impairment charges in 2009 and 2008, this is not necessarily indicative of future periods.

Restructuring charges

We did not incur any restructuring charges in 2010 and 2009.

During the third quarter of 2008, we initiated a restructuring plan as part of a companywide cost saving initiative aimed to reduce
operating costs by moving manufacturing operations from the United States to our primary subsidiary in China. We recorded $1.3 million of expense for severance costs resulting from involuntary termination of employees located in the United States
and China and $0.1 million of expense related to a facility closure.

The cost savings resulting from our restructuring plans
have been fully reflected in the financial statements presented and we do not anticipate any incremental cost savings in the future as a result of the restructuring plan implemented in 2008.

Interest and other income (expense), net

Interest income consists of
income earned on our cash, cash equivalents and short-term investments. Interest expense consists of amounts paid for interest on our short-term and long-term debt borrowings. Other income (expense), net is primarily made up of government subsidies,
share of loss of unconsolidated investee and foreign currency transaction gains and losses. The functional currency of our subsidiaries in China is the RMB and the foreign currency transaction gains and losses of our subsidiaries in China primarily
result from their transactions in U.S. dollars.

Total interest and other income (expense), net decreased by $0.2 million in 2010 compared to 2009,
representing a 24% decrease. The decrease was primarily related to a reduction in interest expense associated with lower outstanding debt in 2010 and lower foreign exchange loss. The decrease was partially offset by a

##### Table of Contents

reduction in interest income, primarily due to lower cash balances. Other income (expense), net remained flat in 2010 compared to 2009 primarily due to a $0.6 million share of loss of
unconsolidated investee, partially offset by a $0.3 million increase in government subsidies received by our China subsidiaries and a $0.2 million decrease in other non-operating material sales in 2010.

Total interest and other income (expense), net remained flat in 2009 compared to 2008. Interest income decreased by $0.1 million in 2009
compared to 2008. While we maintained higher cash balances in 2009, our cash was invested in money market funds with lower interest rates in 2009, but was invested in higher yielding short-term investments for part of 2008. Interest expense
decreased by $0.6 million in 2009 compared to 2008 primarily as a result of paying off one of our term loans in 2008, amortization of debt issuance costs on our U.S. term loans and a lower average balance outstanding under our lines of credit in
China in 2009, as compared to 2008. Other income (expense), net changed by $0.5 million in 2009 compared to 2008 primarily due to our subsidiaries in China realizing more foreign currency transaction gains on transactions denominated in U.S. dollars
in 2008 when the RMB appreciated against the U.S. dollar.

In the future, interest income will depend on our average cash
balances and our investment decisions. We expect interest income to increase in 2011 as a result of proceeds from our initial public offering completed in February 2011. We expect interest expense to vary based on outstanding debt obligations.

Income taxes

We conduct our business globally. However, our operating income is subject to varying rates of tax in the United States and China.
Consequently, our effective tax rate is dependent upon the geographic distribution of our earnings or losses and the tax laws and regulations in each geographical region. We expect that our income taxes will vary in relation to our profitability and
the geographic distribution of our profits. Historically, we have experienced net losses in the United States and in the short term, we expect this trend to continue. In China, one of our subsidiaries has qualified for a preferential 15% tax rate
available for high technology enterprises. The preferential rate applies to 2010, 2009 and 2008. We realized benefits from this 10% reduction in tax rate of $1.7 million, $1.0 million, and $0.2 million for 2010, 2009 and 2008, respectively. We
intend to reapply for the preferential rate for 2011. If approved, the rate will remain at 15% for 2011, 2012 and 2013, otherwise, the rate will be 24% for 2011 and 25% thereafter. In 2009, our cash tax liability in China was partially offset by the
utilization of NOL carryforwards. In future periods, we expect that our operations in China will not have sufficient NOL carryforwards to offset any future cash tax obligation in China.

Our effective tax rate was
41% in 2010, compared with an effective tax rate of negative 39% in 2009. Our operating income is subject to varying rates of tax in the United States and foreign subsidiaries. Consequently, our effective tax rate is dependent upon the geographic
distribution of our earnings or losses and the tax laws and regulations in each geographical region. In 2010, our tax expense incurred was primarily related to the earnings generated by our foreign subsidiaries. Our withholding taxes on royalty
income from foreign sources were offset by a refund from a favorable tax ruling in China and resulted in net impact of zero to our income tax expense in 2010. In 2009, we incurred tax expense despite a consolidated loss before income taxes,
primarily due to foreign income taxes paid based on earnings generated by our foreign subsidiaries of $1.2 million and withholding taxes on royalties received from our foreign subsidiaries of $0.8 million.

The effective tax rate was negative 39% in 2009, compared with an effective tax rate of 6% in 2008. The income tax benefit for 2008
primarily resulted from amortization of a deferred tax liability of $1.3 million relating to intangible assets in a foreign subsidiary and the recognition of refundable U.S. research and development credits of $0.2 million.

Liquidity and capital resources

Until the consummation of our initial public offering in February 2011, we financed our operations through private sales of equity
securities and cash generated from operations and from various lending arrangements. At December 31, 2010, our cash and cash equivalents totaled $25.5 million. Cash and cash equivalents were held for working capital purposes and were invested
primarily in money market funds. We do not enter into investments for trading or speculative purposes. We believe that our existing cash and cash equivalents, and cash flows from our operating activities, will be sufficient to meet our anticipated
cash needs for at least the next 12 months. Our future capital requirements will depend on many factors including our growth rate, the timing and extent of spending to support development efforts, the expansion of sales and marketing activities, the
introduction of new and enhanced products, the costs to increase our manufacturing capacity and the continuing market acceptance of our products. In the event that additional financing is required from outside sources, we may not be able to raise it
on terms acceptable to us or at all. If we are unable to raise additional capital when desired, our business, operating results and financial condition would be adversely affected.

A customary business practice in China is for customers to exchange our accounts receivable with notes receivable issued by their bank.
From time to time we accept notes receivable from certain of our customers in China. These notes receivable are non-interest bearing and are generally due within six months, and such notes receivable may be redeemed with the issuing bank prior to
maturity at a discount. Historically, we have collected on the notes receivable in full at the time of maturity.

Frequently,
we also direct our banking partners to issue notes payable to our suppliers in China in exchange for accounts payable. Our Chinese subsidiaries banks issue the notes to vendors and issue payment to the vendors upon redemption. We owe the
payable balance to the issuing bank. The notes payable are non-interest bearing and are generally due within six months of issuance. As a condition of the notes payable lending arrangements, we are required to keep a compensating balance at the
issuing banks that is a percentage of the total notes payable balance until the notes payable are paid by our subsidiaries in China. These balances are classified as restricted cash on our consolidated balance sheets. As of December 31, 2010,
our restricted cash totaled $3.0 million.

We have lending arrangements with several financial institutions, including a loan
and security agreement with Comerica Bank in the United States, which was amended in December 2009, and several line of credit arrangements for our subsidiaries in China.

As of December 31, 2010, our loan and security agreement in the United States included the following:



| |  |  | An $8.0 million revolving line of credit. Amounts available under the revolving line of credit are reduced by any commercial or stand-by letters of
credit issued under the facility. As of December 31, 2010, we had outstanding $3.0 million under the revolving line of credit and a $5.0 million letter of credit supporting our China line of credit facility. The $3.0 million outstanding under
the line of credit is due in December 2011. As of December 31, 2010, $0.0 million was available under the revolving line of credit.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | A $9.5 million facility under which we can draw down amounts in multiple six month tranches based on our capital expenditures in the United States.
Each drawdown is due and payable in up to 30 equal monthly payments such that all amounts are repaid by June 2013. As of December 31, 2010, $5.8 million was outstanding and is due and payable in equal monthly payments of principal and interest
through June 2013. The capacity for future borrowing is limited by specified maximum amounts. As of December 31, 2010, $3.5 million was available under this facility.
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Our loan and security agreement requires us to maintain certain financial covenants, including a liquidity ratio, and restricts our
ability to incur additional debt or to engage in certain transactions and is secured by substantially all of our U.S. assets, other than intellectual property assets. As of December 31, 2010, we were in compliance with all covenants contained
in this agreement.

##### Table of Contents

Our primary subsidiary in China has a $5.0 million line of credit facility with a Hong Kong
bank. This line of credit agreement is supported by letters of credit issued pursuant to our U.S. loan and security agreement, as referenced above. As of December 31, 2010, we had repaid the $5.0 million line of credit in full, and $5.0 million
was available under the line of credit.

In addition to the $5.0 million line of credit facility for our primary subsidiary in
China referenced above, our subsidiaries in China also have short-term line of credit facilities with several banking institutions. These short-term loans have an original maturity date of one year or less as of December 31, 2010 and bear
interest at rates ranging from 4.76% to 5.84%. Amounts requested by us are not guaranteed and are subject to the banks funds and currency availability. The short-term loan agreements do not contain financial covenants and one such loan
agreement is secured by our main manufacturing facility in China. As of December 31, 2010, we had an aggregate of $4.5 million of short-term loans outstanding.

The table below sets forth selected cash flow data for the periods presented:

In February 2011, we completed an initial public offering of common stock, raising net proceeds of $88.2
million before offering expenses. In connection with the closing of the initial public offering, all of the shares of Series 1, Series 2 and Series 3 preferred stock outstanding automatically converted into 6,639,513 shares of common stock on a
1-for-1 basis and all of the shares of Series X preferred stock outstanding automatically converted into 7,398,976 shares of common stock on a 400-for-1 basis.

We intend to use our net proceeds from the 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 the offering, and investors will be relying on managements judgment regarding the application of these net proceeds. We also may use a portion of our net proceeds from the offering to acquire
complementary businesses, products, services or technologies, but 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 outstanding indebtedness.

Operating activities

In 2010, net cash provided by operating activities was $11.1 million. Cash provided by operating activities was primarily related to cash receipts from customers in excess of cash payments to our
employees and suppliers. During the year ended December 31, 2010, we recognized net income of $3.3 million. However, that net income incorporated non-cash charges, including depreciation and amortization of $12.1 million, stock-based
compensation expenses of $1.6 million and non-cash increases to our asset reserve accounts of $1.6 million. These amounts were partially offset as we spent an additional $6.0 million to increase our inventories to meet customer demands of seasonally
higher sales volumes in the second and third quarter of the year and for future sales and a $5.6 million increase in prepaid expenses, primarily associated with our initial public offering. However, not all of the inventory purchases were paid for
during the year ended December 31, 2010, due to extended payment terms with certain suppliers, as evidenced by our net increase in accounts payable and accrued liabilities of $4.1 million during the period.

##### Table of Contents

In 2009, net cash provided by operating activities was $11.8 million. Cash provided by
operating activities primarily related to cash receipts from customers in excess of cash payments to our employees and suppliers. During the year ended December 31, 2009, we recognized a net loss of $6.8 million. However, that net loss
incorporated non-cash charges, including depreciation and amortization of $13.6 million, asset impairment charges of $1.2 million and stock-based compensation expense of $1.0 million and we recorded non-cash increases to our asset reserve accounts
of $1.9 million. Furthermore, we experienced increase in revenues and higher collections. Our uses of cash were partially offset by reduced inventories resulting from continued improvement in our inventory turns and extended payment terms to
suppliers as evidenced by an increase in our accounts payable and accrued and other liabilities.

In 2008, net cash used in
operating activities was $15.3 million. Cash used in operating activities primarily related to payments to suppliers and employees in excess of cash received from our customers from the sale of our products. Although we experienced a 39.8% increase
in revenue from 2007 to 2008, our accounts receivables increased by 50.9%, or $15.3 million, primarily due to growth in our international receivables, which typically have longer payment terms. During the year ended December 31, 2008, we
recognized a net loss of $28.0 million. However, that net loss incorporated non-cash charges, including depreciation and amortization of $13.5 million, asset impairment charges of $4.0 million and stock-based compensation expense of $1.1 million.
Our uses of cash were partially offset by reduced inventories resulting from improved inventory turns and extended payment terms to suppliers, as evidenced by an increase in our accounts payable and accrued and other liabilities.

Investing activities

Our investing activities consisted primarily of capital expenditures and in 2010, included purchases of equity securities.

In 2010, net cash used for investing activities was $24.7 million. We purchased $15.8 million of capital equipment and invested $8.1
million in shares of a non-U.S. publicly listed company. In addition, we completed our sale of Archcom and, as a result, received the remaining $0.6 million in cash proceeds, offset by the transfer of the cash of Archcom of $1.7 million to the
buyer.

In 2009, we used $6.0 million of cash for investing activities, comprised of $4.6 million of capital expenditures
associated with the purchase of machinery and equipment and software to enhance and support our manufacturing operations, an increase of $1.8 million in restricted cash associated with our notes payable in China, partially offset by $1.0 million of
cash provided by the sale of property, plant and equipment and the expected sale of Archcom.

In 2008, we used $6.7 million of
cash for investing activities. We used $11.1 million of cash for the purchase of property and equipment, primarily associated with expansion of our manufacturing operations in China, partially offset by $4.1 million of cash provided by the sales and
maturities of short-term investments.

Financing activities

Our financing activities consisted primarily of proceeds from the issuance of preferred stock and activity associated with our various lending arrangements.

In 2010, net cash used for financing activities was $4.9 million. We repaid $9.6 million, net of our bank loans, repaid $1.3 million, net
of our notes payable, and received $6.0 million in cash from the issuance of preferred stock.

In 2009, our financing
activities provided $9.0 million in cash, primarily resulting from $8.9 million of cash proceeds from the issuance of preferred stock and $5.2 million of net proceeds from notes payable. Our proceeds were offset by $5.1 million of net payments on
our outstanding bank loans.

Off-balance sheet arrangements

During the years ended December 31, 2010, 2009 and 2008, we did not have any significant off-balance sheet arrangements, as defined in Item 303(a)(4)(ii) of Regulation S-K.

Recent accounting pronouncements

In September 2009, the Financial Accounting Standards Board, or FASB, reached final consensus on a new revenue recognition guidance regarding revenue arrangements with multiple deliverables. The new
accounting guidance addresses how to determine whether an arrangement involving multiple deliverables contains more than

##### Table of Contents

one unit of accounting, and how the arrangement consideration should be allocated among the separate units of accounting. The new accounting guidance is effective for the Company beginning
January 1, 2011 and may be applied retrospectively or prospectively for new or materially modified arrangements. In addition, early adoption is permitted. We do not expect that the adoption of the guidance will have a material impact on our
financial position, results of operations or cash flows.

In January 2010, the FASB issued amended guidance on fair value
measurements and disclosures. The new guidance requires additional disclosures regarding fair value measurements, amends disclosures about postretirement benefit plan assets, and provides clarification regarding the level of disaggregation of fair
value disclosures by investment class. This guidance is effective for interim and annual reporting periods beginning after December 15, 2009, except for certain Level 3 activity disclosure requirements that will be effective for reporting
periods beginning after December 15, 2010. Accordingly, the Company adopted this amendment for year ended December 31, 2010, except for the additional Level 3 requirements which will be adopted in 2011. Level 3 assets and liabilities are
those whose fair market value inputs are unobservable and reflect managements best estimate of what market participants would use in pricing the asset or liability at the measurement date. We do not expect the adoption of the guidance to have
a material impact on our consolidated financial statements.

In April 2010, the FASB issued an accounting standard update
which provides guidance on the criteria to be followed in recognizing revenue under the milestone method. The milestone method of recognition allows a vendor who is involved with the provision of deliverables to recognize the full amount of a
milestone payment upon achievement, if, at the inception of the revenue arrangement, the milestone is determined to be substantive as defined in the standard. The guidance is effective on a prospective basis for milestones achieved in fiscal years
and interim periods within those fiscal years, beginning on or after June 15, 2010. Early adoption is permitted. We do not expect the adoption of the guidance to have a material impact on our consolidated financial statements.



|ITEM 7A. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|-------- | ----------------------------------------------------------

Interest rate fluctuation risk

Our cash equivalents consisted primarily of
money market funds and interest and non-interest bearing bank deposits. The main objective of these instruments was safety of principal and liquidity while maximizing return, without significantly increasing risk. Given the short-term nature of our
cash equivalents, we do not anticipate any material effect on our portfolio due to fluctuations in interest rates.

We are
exposed to market risk due to the possibility of changing interest rates associated with certain outstanding balances under our debt instruments. As of December 31, 2010, the interest rates on all of our outstanding debt in China were fixed at
the time of drawdown, and were not subject to fluctuations. As of December 31, 2010, a portion of our U.S. debt was based on floating rates of interest and is subject to fluctuations in interest rates. As of December 31, 2010, we had not
hedged our interest rate risk.

As of December 31, 2010, we had $8.8 million outstanding under our U.S. credit
facilities, which was subject to fluctuations in interest rates. As of December 31, 2010, the weighted average interest rate on the $8.8 million of outstanding principal subject to interest rate fluctuations was 4.34%. A hypothetical 10%
increase in the interest rate could result in approximately $38,000 of additional annual interest expense. A hypothetical 10% increase in the interest rate could result in approximately $10,000 of additional annual interest expense. The hypothetical
changes and assumptions made above will be different from what actually occurs in the future. Furthermore, the computations do not anticipate actions that may be taken by our management should the hypothetical market changes actually occur over
time. As a result, actual impacts on our results of operations in the future will differ from those quantified above.

Foreign currency
exchange risk

Foreign currency exchange rates are subject to fluctuation and may cause us to recognize transaction gains
and losses in our statement of operations. A substantial portion of our business is conducted through our

subsidiaries in China whose functional currency is the RMB. To the extent that transactions by our subsidiaries in China are denominated in currencies other than RMB, we bear the risk that
fluctuations in the exchange rates of the RMB in relation to other currencies could decrease our revenue and increase our costs and expenses. During the years ended December 31, 2010 and 2009, we recognized foreign currency transaction losses
of $0.1 million and $0.1 million, respectively. We use the U.S. dollar as the reporting currency for our consolidated financial statements. Any significant revaluation of the RMB may materially and adversely affect our results of operations upon
translation of our Chinese subsidiaries financial statements into U.S. dollars. While we generate a majority of our revenue in RMB, a majority of our operating expenses are in U.S. dollars. Therefore a depreciation in RMB against the U.S.
dollar would negatively impact our revenue upon translation to the U.S. dollars but the impact on operating expenses would be less. For example, for the year ended December 31, 2010, a 10% depreciation in RMB against the U.S. dollar would have
resulted in a $10.6 million decrease in our revenue and a $1.3 million decrease in our net income for the period. Comparatively, for the year ended December 31, 2009, a 10% depreciation in RMB against the U.S. dollar would have resulted in
an $11.8 million decrease in our revenue and a $1.2 million increase in our net loss in 2009.

To date, we have not entered
into any hedging transactions in an effort to reduce our exposure to foreign currency exchange risk. While we may decide to enter into hedging transactions in the future, the availability and effectiveness of these hedging transactions may be
limited and we may not be able to successfully hedge our exposure. In addition, our currency exchange variations may be magnified by any Chinese exchange control regulations that restrict our ability to convert RMB into foreign currency.

Inflation risk

Inflationary factors, such as increases in our cost of goods sold and operating expenses, may adversely affect our results of operations.
Although we do not believe that inflation has had a material impact on our financial position or results of operations to date, an increase in the rate of inflation in the future, particularly in China, may have an adverse affect on our levels of
gross profit and operating expenses as a percentage of revenue if the sales prices for our products do not proportionately increase with these increased expenses.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

NeoPhotonics Corporation

In our opinion, the accompanying consolidated balance
sheets and the related consolidated statements of operations, consolidated statements of redeemable convertible preferred stock, deficit and comprehensive income (loss) and consolidated statements of cash flows present fairly, in all material
respects, the financial position of NeoPhotonics Corporation and its subsidiaries (the Company) at December 31, 2010 and December 31, 2009, and the results of their operations and their cash flows for each of the three years in
the period ended December 31, 2010 in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Companys management. Our responsibility is to express
an opinion on these financial statements based on our audits. We conducted our audits of these statements 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,
assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

As discussed in Note 1 of Notes to Consolidated Financial Statements, the Company changed the manner in which it accounts for
noncontrolling interests effective January 1, 2009.

NEOPHOTONICS CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. The company and basis of presentation

Business and organization

NeoPhotonics Corporation (NeoPhotonics or the Company) is a designer and manufacturer of PIC-based modules and
subsystems for bandwidth-intensive, high-speed communications networks. NeoPhotonics, formerly known as NanoGram Corporation, was incorporated in Delaware on October 31, 1996 to develop nanoparticles for use in industrial applications. In
November 2002, the Company spun out two companies, changed its name to NeoPhotonics Corporation, and focused on the design, development and manufacturing of planar lightwave circuits for optical communication platforms. During the period from
January 2003 through March 2003, NeoPhotonics completed a series of reorganization transactions whereby the Company spun-off part of its business in the form of two subsidiaries, NanoGram Devices Corporation (NDC) and NanoGram
Corporation (NanoGram). In March 2003, the Company acquired Lightwave Microsystems Corporation (LMC) and subsequently began to market standard and semi-custom planar lightwave circuits-based components and modules for
metro access and other advanced optical communications platforms. In March 2004, NDC was acquired by Greatbatch Inc. NanoGram was acquired by Teijin Limited in July 2010.

On November 17, 2003, the Company filed a petition for relief under Chapter 11 of the federal bankruptcy laws in the United States Bankruptcy Court for the Northern District of California. Under
Chapter 11, certain claims against the Company in existence prior to the filing of the petition for relief under the federal bankruptcy laws are stayed while the Company continues business operations as a debtor-in-possession. These claims were
reflected as liabilities subject to compromise in the Companys consolidated financial statements for the year ended December 31, 2003. On February 26, 2004, the Bankruptcy Court confirmed the Companys plan of reorganization.
The Companys plan of reorganization was substantially consummated on March 26, 2004, at which point the Company emerged from bankruptcy and was recapitalized.

Out-of-Period Adjustments

In the three months ended December 31, 2010, the
Company recorded an out-of-period adjustment to reduce deferred tax assets by $215,000. The correction of this error resulted in a reduction to the Companys net income of $215,000 for the year ended December 31, 2010. The resulting error also
reduced net loss for the year ended December 31, 2009 by $215,000. Management has assessed the impact of this adjustment and does not believe that the amounts were material to any prior period financial statements, and the impact of correcting this
error in the three months ended December 31, 2010 is not material to the financial statements for the year ended December 31, 2010.

Consolidation

The
consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) and include the consolidated accounts of the Company and its majority owned
subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. Effective January 1, 2009, the Company adopted Financial Accounting Standards Board (FASB) authoritative guidance requiring that a
noncontrolling interest held by others in a companys majority-owned subsidiaries be part of the equity of the controlling group and reported on the balance sheet within the equity section as a distinct item separate from the companys
equity. In accordance with this guidance, minority interests have been re-captioned to noncontrolling interests and reported separately in deficit for 2010 and prior periods. In addition, net income attributable to noncontrolling interests has been
presented below net income (loss) in arriving at net income (loss) attributable to NeoPhotonics Corporation for 2010 and prior periods.

Reverse stock split

On
November 29, 2010, the Company filed its Amended and Restated Certificate of Incorporation which effected a 1-for-25 reverse stock split of all outstanding shares of the Companys stock, including common stock



71

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



and redeemable convertible preferred stock. Fractional shares of Series X preferred stock were issued. Any fractional shares of common stock and Series 1, 2 and 3 preferred stock resulting from
the reverse stock split were settled in cash equal to the fraction of a share to which the holder was entitled.

Following the
amendment, the Companys authorized capital stock consisted of 21,420,000 shares, comprising: (i) 14,000,000 shares of common stock, par value $0.0025 per share, (ii) 20,000 shares of Series X redeemable convertible preferred stock,
par value $0.0025 per share, and (iii) 7,400,000 shares of Series 1, 2 and 3 redeemable convertible preferred stock, par value $0.0025 per share.

All shares, stock options, warrants to purchase common stock and per share information presented in the consolidated financial statements has been adjusted to reflect the reverse stock split on a
retroactive basis for all periods presented and all share information is rounded down to the nearest whole share after reflecting the reverse stock split.

Initial Public Offering (unaudited)

In February 2011, the Company
completed its initial public offering of 8,625,000 shares of its common stock, including the full underwriters over-allotment option, at a public offering price of $11.00 per share. Net cash proceeds from the initial public offering
were approximately $88.2 million, prior to deducting offering expenses.

In connection with the closing of the initial
public offering, all of the shares of Series 1, Series 2 and Series 3 preferred stock outstanding automatically converted into 6,639,513 shares of common stock on a 1-for-1 basis and all of the shares of Series X preferred stock outstanding
automatically converted into 7,398,976 shares of common stock on a 400-for-1 basis.

On February 10, 2011, the Company
filed its Amended and Restated Certificate of Incorporation in connection with the closing of its initial public offering. Following the amendment, the Companys authorized capital stock consisted of 110,000,000 shares, comprising:
(i) 100,000,000 shares of common stock, par value $0.0025 per share and (ii) 10,000,000 shares of preferred stock, par value $0.0025 per share.

As the IPO was completed in February 2011, these transactions are not reflected in the consolidated financial statements as of December 31, 2010.

Condensed parent company financial data

The Companys subsidiaries in China are required to set aside at least 10% of their respective accumulated profits each year, if any, to fund their statutory common reserves until such reserves have
reached at least 50% of their respective registered capital. As of December 31, 2010, the Companys subsidiaries in China had restricted net assets of approximately $5.3 million as calculated pursuant to paragraph 4-08(e)(3) of Regulation
S-X. The restricted net assets exceeded 25% of the consolidated net assets of the Company as of December 31, 2010 as a result of the Companys redeemable convertible preferred stock being classified as mezzanine capital, rather than as a
component of stockholders deficit. Mezzanine capital is treated as a liability when determining consolidated net assets, which results in consolidated liabilities in excess of consolidated assets as of December 31, 2010. For further
information, see Note 18.

Upon completion of the Companys initial public offering, all of the outstanding shares
of redeemable convertible preferred stock were converted into shares of common stock and are no longer treated as a liability when determining consolidated net assets. As a result, the restricted net assets of the Companys China-based
subsidiaries are not expected to exceed 25% of the consolidated net assets of the Company.

2. Summary of significant accounting policies

Use of estimates

The
preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the
financial statements and the reported revenue and expenses during the reporting period. Significant estimates made by management include: the useful lives of property, plant and equipment and intangible assets as well as future cash flows to be
generated by those assets; allowances for doubtful accounts; valuation allowances for deferred tax assets; reserves for excess and obsolete inventories and fair value of the Companys common stock, stock options and preferred stock, among
others. Actual results could differ from these estimates.

Fair value of financial instruments

The carrying values of cash and cash equivalents, accounts receivable and accounts payable approximate their respective historical fair
values due to their short-term maturities.

Concentration of credit risk and significant customers

Financial instruments that potentially subject the Company to concentrations of credit risk are primarily cash and cash equivalents and
trade accounts receivable. The Companys investment policy requires cash and cash equivalents to be placed with high-credit quality institutions and to limit the amount of credit risk from any one issuer. The Company performs ongoing credit
evaluations of its customers financial condition whenever deemed necessary and generally does not require collateral. The Company maintains an allowance for doubtful accounts based upon the expected collectibility of all accounts receivable,
which takes into consideration an analysis of historical bad debts, specific customer creditworthiness and current economic trends. For the years ended December 31, 2010, 2009 and 2008, the Company provided $0.4 million, $0.7 million and $0.6
million, respectively, for allowance for doubtful accounts. The following table sets forth the Companys significant customers:



|           |  |                                      |    |   |                                            |  |    |      |  |  |      |   |  |      |    |   |  |  |    |

|- | ------------------------------------------------------

Cash and cash equivalents

Highly liquid investments with a maturity of
90 days or less at the date of purchase are considered cash equivalents. Cash equivalents consist principally of investments in money market funds.

Restricted cash

As a condition of the notes payable lending arrangements
of the Companys subsidiaries in China, these subsidiaries are required to keep a compensating balance at the issuing banks that is a percentage of the total notes payable balance until the notes payable are paid. These balances have been
excluded from the Companys cash and cash equivalents balance and are classified as restricted cash on the Companys consolidated balance sheets. As of December 31, 2010 and 2009, the amount of restricted cash was $3.0 million and
$3.3 million, respectively.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



Investments

Equity securities are classified as available-for-sale and are reported at fair market value and unrealized gains and losses are included in accumulated other comprehensive income (loss) as a separate
component of stockholders deficit in the consolidated balance sheets. The Companys investment in equity securities is classified as long-term based on the Companys intent and ability to hold the investment for more than 12 months
from the balance sheet date. The Company does not hold its securities for trading or speculative purposes.

Accounts receivable

Accounts receivable include trade receivables and notes receivables from customers. The Company receives notes receivable
from certain customers in China that are secured by the customers affiliated financial institution. The notes are generally due within 6 months and may be redeemed early by the Company at a discount. Historically, the Company has collected on
the notes receivable in full at the time of maturity. The notes receivable do not meet the true sales criteria as defined by the accounting guidance for accounting for transfers and servicing of financial assets.

An allowance for doubtful accounts is calculated based on the aging of the Companys trade receivables, historical experience, and
management judgment. The Company writes off trade receivables against the allowance when management determines a balance is uncollectible and no longer actively pursues collection of the receivable.

Inventories

Inventories
consist of on-hand raw materials, work-in-progress inventories and finished goods. Raw materials and work-in-progress inventories are stored mainly on the Companys premises. Finished goods are stored on the Companys premises as well as
on consignment at certain customer sites.

Inventories are stated at the lower of standard cost, which approximates actual
cost determined on the weighted average basis, or market value. Inventories are recorded using the first-in, first-out method. The Company routinely evaluates quantities and values of inventories in light of current market conditions and market
trends, and records a write-down for quantities in excess of demand and product obsolescence. The evaluation may take into consideration historic usage, expected demand, anticipated sales price, new product development schedules, the effect new
products might have on the sale of existing products, product obsolescence, customer concentrations, product merchantability and other factors. Market conditions are subject to change and actual consumption of inventory could differ from forecasted
demand. The Company also regularly reviews the cost of inventories against their estimated market value and records a lower of cost or market reserve for inventories that have a cost in excess of estimated market value. Once a reserve for
inventories is recorded, this results in a new cost basis for the related inventories which is not reversed.

Goodwill

Goodwill represents the excess of the purchase price over the fair value of the net tangible assets, identifiable intangible assets and
in-process research and development acquired in a business combination. Goodwill is not subject to amortization, but is subject to at least an annual assessment for impairment.

The Company evaluates goodwill, at a minimum, on an annual basis and whenever events and changes in circumstances suggest that the
carrying amount may not be recoverable. The Company performs its annual goodwill impairment testing as of December 31 of each year. Goodwill is reviewed for impairment utilizing a two-step process. First, impairment of goodwill is
tested at the reporting unit level by comparing the reporting units carrying amount, including goodwill, to the fair value of the reporting unit. The fair value of the reporting



74

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



unit is estimated using a discounted cash flow approach. If the carrying amount of the reporting unit exceeds its fair value, a second step is performed to measure the amount of impairment
loss, if any. In step two, the implied fair value of goodwill is calculated as the excess of the fair value of a reporting unit over the fair values assigned to its assets and liabilities. If the implied fair value of goodwill is less than the
carrying value of the reporting units goodwill, the difference is recognized as an impairment loss. The Company considers that it has only one reporting unit for the purposes of testing goodwill for impairment. A reporting unit is an operating
segment or one level below an operating segment (referred to as a component). A component of an operating segment is a reporting unit if the component constitutes a business for which discrete financial information is available and segment
management regularly reviews the operating results of that component. The Company did not recognize any goodwill impairment charges during the years ended December 31, 2010, 2009 and 2008.

Long-lived assets

Property, plant and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation and amortization is
computed using the straight-line method over the following estimated useful lives:



|                                         |  |                                  
|---------------------------------------- |  | ---------------------------------
|Buildings                                |  | 20-30 years                      
|Machinery and equipment                  |  | 5 years                          
|Furniture, fixtures and office equipment |  | 5 years                          
|Software                                 |  | 5-7 years                        
|Leasehold improvements                   |  | 5 years or lease term, if shorter

Repairs
and maintenance costs are expensed as incurred.

Intangible assets acquired in a business combination are recorded at fair
value. Identifiable finite-lived intangible assets are amortized over the period of estimated benefit using the straight-line method, reflecting the pattern of economic benefits associated with these assets. The estimated useful lives of the
Companys intangible assets generally range from five to seven years, except for acquired land use rights in China, which have an estimated useful life of 45 years.

The carrying value of intangible assets and other long-lived assets is reviewed on a regular basis for the existence of facts or circumstances, both internally and externally, that may suggest impairment.
Some factors which the Company considers to be triggering events for impairment review include a significant decrease in the market value of an asset, a significant change in the extent or manner in which an asset is used, a significant adverse
change in the business climate that could affect the value of an asset, an accumulation of costs for an asset in excess of the amount originally expected, a current period operating loss or cash flow decline combined with a history of operating loss
or cash flow uses or a projection that demonstrates continuing losses and a current expectation that, it is more likely than not, a long-lived asset will be disposed of at a loss before the end of its estimated useful life.

If one or more of such facts or circumstances exist, the Company will evaluate the carrying value of long-lived assets to determine if an
impairment exists, by comparing it to estimated undiscounted future cash flows over the remaining useful life of the assets. If the carrying value of the assets is greater than the estimated future cash flow, the assets are written down to the
estimated fair value. The Companys cash flow estimates contain managements best estimates, using appropriate and customary assumptions and projections at the time. Any write-down would be treated as a permanent reduction in the carrying
amount of the asset and an operating loss would be recognized. During the year ended December 31, 2010, no impairment charges were recognized. During the years ended December 31, 2009 and 2008, impairment charges relating to finite lived
assets of $1.2 million and $4.0 million, respectively, were recognized. See Note 5 for further discussion.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



In those cases where the Company determines that the useful life of an asset should be
revised, the Company depreciates the remaining net book value over the new estimated useful life.

Revenue recognition

Revenue is derived from the sale of the Companys products. The Company recognizes revenue provided that persuasive
evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable and collectability is reasonably assured. Contracts and/or customer purchase orders are used to determine the existence of an arrangement. Delivery is
considered to have occurred when title and risk of loss have transferred to the customer. The price is equal to the amount invoiced to the customer and is not subject to adjustment and customers do not have the right of return. The Company evaluates
the creditworthiness of its customers to determine that appropriate credit limits are established prior to the acceptance of an order.

Revenue is recognized when the product is shipped and title has transferred to the buyer. The Company bears all costs and risks of loss or damage to the goods up to that point. On most orders, the
Companys shipment terms provide that title passes to the buyer upon shipment by the Company. Other shipment terms may provide that title passes to the buyer upon delivery of the goods to the buyer. Shipping and handling costs are included in
the cost of goods sold. The Company presents revenue net of sales taxes and any similar assessments.

The Company recognizes
revenue on sales to distributors at the time of shipment or delivery to the distributors, as the distributors do not have extended rights of return, subsequent price discounts or price protection.

Product warranties

The Company provides warranties to cover defects in workmanship, materials and manufacturing for a period of one to two years to meet the stated functionality as agreed to in each sales arrangement.
Products are tested against specified functionality requirements prior to delivery, but the Company nevertheless from time to time experiences claims under its warranty guarantees. The Company accrues for estimated warranty costs under those
guarantees based upon historical experience, and for specific items, at the time their existence is known and the amounts are determinable.

The table below summarizes the movement in the warranty accrual (in thousands):



|                            |  |                          |      |   |      |   |      |      |  |   |      |

Research and development

Research and development expense consists of personnel costs, including stock-based compensation expense, for the Companys research and development personnel and product development costs, including
engineering services, development software and hardware tools, depreciation of capital equipment and facility costs. Research and development costs are expensed as incurred.

Advertising costs

Advertising costs are expensed as incurred and, to date, have not been significant.

Stock-based compensation

Effective January 1, 2006, the Company adopted new authoritative accounting guidance for stock-based compensation, which requires enterprises to measure the cost of employee services received in
exchange for an award of equity instruments, including stock options, based on the grant date fair value of the award. The Company adopted the new guidance using the prospective transition method. Under this transition method, beginning
January 1, 2006, employee stock-based compensation cost recognized includes: (a) compensation cost for all stock-based payments granted prior to, but not yet vested as of December 31, 2005, based on the intrinsic value method, and
(b) compensation cost for all stock-based payments granted or modified subsequent to December 31, 2005, based on the grant date fair value estimated in accordance with the new guidance.

The Companys determination of the fair value of stock options on the date of grant utilizes an option-pricing model, and is
impacted by its common stock price as well as changes in assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to, expected common stock price volatility over the term of the option
awards, as well as the projected employee option exercise behaviors (expected period between stock option vesting date and stock option exercise date), risk-free interest rates and expected dividends.

The fair value is recognized over the period during which an employee is required to provide services in exchange for the option award,
known as the requisite service period (usually the vesting period) on a straight-line basis. Stock-based compensation expense recognized at fair value includes the impact of estimated forfeitures. The Company estimates future forfeitures at the date
of grant and revises the estimates, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

Cash flows resulting from the tax benefits for tax deductions from the exercise of stock options in excess of the compensation expense
recorded for those options (excess tax benefits) are classified as cash flows from financing activities. The Company had no excess tax benefits in the years ended December 31, 2010, 2009 and 2008.

The Company grants stock appreciation rights to certain individuals, including employees, directors or consultants. Upon the exercise of
a stock appreciation right, the Company will pay the participant an amount equal to the product of (a) the excess of the per share fair market value of the Companys common stock on the date of exercise over the strike price, multiplied by
(b) the number of shares of common stock with respect to which the stock appreciation right is exercised. An award under the plan is not exercisable until the earlier of an initial public offering or a change in control in the Company. The
Company has not recognized compensation expense relative to these awards as neither of these events has occurred and therefore the employees were not able to exercise their rights. Upon one of the above events occurring, an expense and an equal
liability for the stock appreciation rights will be recorded, equal to the fair value of the vested portion of the award on the date that the event occurs calculated using the Black-Scholes option pricing model. Each reporting period thereafter,
compensation expense will be recorded, based on the remaining service period and the then fair value of the award until vesting of the award is completed. After vesting is completed, the Company will continue to remeasure the fair value of the
liability until the award is exercised, with changes in the fair value of the liability recorded in the consolidated statements of operations.

For further details of the Companys stock-based compensation arrangements, see Note 12.

Income taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the
future tax consequences attributable to differences between the carrying amounts of existing assets and liabilities in the financial statements and their respective tax bases, and operating loss and tax credit carryforwards. Deferred tax assets
and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities from a change
in tax rates is recognized in the consolidated statement of operations in the period that includes the enactment date.

The
Company operates in various tax jurisdictions and is subject to audit by various tax authorities. In preparing the Companys consolidated financial statements, the Company is required to estimate its taxes in each of the jurisdictions in which
it operates. The Company estimates actual current tax exposure as well as assesses temporary differences resulting from different treatment of items, such as accruals and allowances not currently deductible for tax purposes. These differences result
in deferred tax assets which represent future tax benefits to be received when certain expenses previously recognized in the financial statements become deductible expenses under applicable income tax laws, or loss credit carryforwards are utilized.

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some
portion or all of a deferred tax asset 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. A valuation
allowance is recorded for loss carryforwards and other deferred tax assets where it is more likely than not that such deferred tax assets will not be realized.

Foreign currency translations

Monetary assets and liabilities denominated
in currencies other than the U.S. dollar are translated into U.S. dollars at the rates of exchange at the balance sheet date. Transactions in currencies other than the U.S. dollar during the year are converted into the U.S. dollar at the applicable
rates of exchange prevailing on the day transactions occurred. Transaction gains and losses are recognized in other income (expense), net in the consolidated statements of operations. Exchange gains (losses) recognized were ($0.1) million,
($0.1) million, and $0.8 million for the years ended December 31, 2010, 2009 and 2008, respectively.

The financial
records of certain of the Companys subsidiaries are maintained in local currencies other than the U.S. dollar, such as the Chinese Renminbi (RMB), which are their functional currencies. Assets and liabilities are translated at the
exchange rates at the balance sheet date, equity accounts are translated at historical exchange rates and revenue, expenses, gains and losses are translated using the average exchange rate for the period. Translation adjustments are reported as
foreign currency translation adjustments and are shown as a separate component of other comprehensive income (loss) in the consolidated statements of redeemable convertible preferred stock, deficit and comprehensive income (loss).

Net income (loss) per share attributable to NeoPhotonics Corporation common stockholders

The Company applies the two-class method for calculating and presenting net income (loss) per share attributable to NeoPhotonics
Corporation common stockholders. Under the two-class method, net income is allocated between common shares and other participating securities based on their participating rights. Participating securities are defined as securities that participate in
dividends with common shares according to a predetermined formula. Basic net income (loss) per share attributable to NeoPhotonics Corporation common stockholders is calculated by dividing net income (loss) attributable to NeoPhotonics Corporation
common stockholders by the weighted average number of shares outstanding for the period.

Diluted net income (loss) per share attributable to NeoPhotonics Corporation common
stockholders is calculated by dividing net income (loss) attributable to NeoPhotonics Corporation common stockholders and income allocable to participating securities to the extent they are dilutive, by the weighted average number of common shares
and potential dilutive common share equivalents outstanding during the period if the effect is dilutive. The Companys potential dilutive common share equivalents consist of incremental common shares issuable upon the exercise of options and
warrants to purchase common shares and upon conversion of its redeemable convertible preferred stock.

Effective
January 1, 2009, the Company adopted the new accounting guidance for determining whether instruments granted in share-based payment transactions are participating securities. All prior period net income (loss) per share attributable to
NeoPhotonics Corporation common stockholders data presented has been prepared to conform with the provisions of this accounting guidance. The guidance clarified that share-based payment awards that have not yet vested meet the definition of a
participating security provided the right to receive the dividend is non-forfeitable and non-contingent. These participating securities are therefore included in the computation of basic net income (loss) per share under the two-class method. The
Company has concluded that its non-vested early-exercised stock options meet the definition of a participating security and should be included in the Companys computation of basic net income (loss) per share attributable to NeoPhotonics
Corporation common stockholders. The Company also concluded that for the years ended December 31, 2010, 2009 and 2008, its redeemable convertible preferred stock does not meet the definition of a participating security as the stockholders of
the redeemable convertible preferred stock do not have a contractual obligation to share in the Companys losses.

Comprehensive income (loss)

Comprehensive income (loss) includes all changes in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. Comprehensive income (loss)
consists of net income (loss), foreign currency translation adjustments, unrealized gains or losses on cost method investments and net income attributable to noncontrolling interests. Comprehensive income (loss) is disclosed in the consolidated
statements of redeemable convertible preferred stock, deficit and comprehensive income (loss). The components of accumulated other comprehensive income as of December 31, 2010, include $4.4 million of unrealized gains on cost method investments
and $8.4 million of cumulative foreign currency translation adjustments. The components of accumulated other comprehensive income as of December 31, 2009 and 2008, include only foreign currency translation adjustments.

Recent accounting pronouncements

In September 2009, the Financial Accounting Standards Board, or FASB, reached final consensus on a new revenue recognition guidance regarding revenue arrangements with multiple deliverables. The new
accounting guidance addresses how to determine whether an arrangement involving multiple deliverables contains more than one unit of accounting, and how the arrangement consideration should be allocated among the separate units of accounting. The
new accounting guidance is effective for the Company beginning January 1, 2011 and may be applied retrospectively or prospectively for new or materially modified arrangements. In addition, early adoption is permitted. The Company does not
expect that the adoption of the guidance will have a material impact on its financial position, results of operations or cash flows.

In January 2010, the FASB issued amended guidance on fair value measurements and disclosures. The new guidance requires additional disclosures regarding fair value measurements, amends disclosures
about postretirement benefit plan assets, and provides clarification regarding the level of disaggregation of fair value disclosures by investment class. This guidance is effective for interim and annual reporting periods beginning after
December 15, 2009, except for certain Level 3 activity disclosure requirements that will be effective for

reporting periods beginning after December 15, 2010. Accordingly, the Company adopted this amendment for year ended December 31, 2010, except for the additional Level 3 requirements
which will be adopted in 2011. Level 3 assets and liabilities are those whose fair market value inputs are unobservable and reflect managements best estimate of what market participants would use in pricing the asset or liability at the
measurement date.

In April 2010, the FASB issued an accounting standard update which provides guidance on the criteria to be
followed in recognizing revenue under the milestone method. The milestone method of recognition allows a vendor who is involved with the provision of deliverables to recognize the full amount of a milestone payment upon achievement, if, at the
inception of the revenue arrangement, the milestone is determined to be substantive as defined in the standard. The guidance is effective on a prospective basis for milestones achieved in fiscal years and interim periods within those fiscal years,
beginning on or after June 15, 2010. Early adoption is permitted. The Company does not expect the adoption of the guidance to have a material impact on our consolidated financial statements.

3. Fair value measurements

Fair value is defined as the price at which an asset could be exchanged in a current transaction between knowledgeable, willing parties. A liabilitys fair value is defined as the amount that would
be paid to transfer the liability to a new obligor, not the amount that would be paid to settle the liability with the creditor. Where available, fair value is based on observable market prices or parameters or derived from such prices or
parameters. Where observable prices or inputs are not available, valuation models are applied. These valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the price transparency for the
instruments or market and the instruments complexity. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The authoritative accounting guidance describes
a fair value hierarchy based on three levels of inputs that may be used to measure fair value, of which the first two are considered observable and the last is considered unobservable. These levels of inputs are as follows:

Level 1Observable inputs such as unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement
date.

Level 2Inputs (other than quoted prices included in Level I) are either directly or indirectly observable for the
asset or liability. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.

Level 3Unobservable inputs that reflect managements best estimate of what market participants would use in pricing the asset
or liability at the measurement date. Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.

Assets measured at fair value

The Companys financial instruments are
valued using quoted prices in active markets or based upon other observable inputs. The following table sets forth the fair value of the Companys financial assets as of the date presented (in thousands):

5. Impairment of assets

In 2008, the Company discontinued the production of a tunable laser product based on factors that included an accumulation of costs for the asset group in excess of the amount originally expected, a
current period operating loss and continuing cash flow decline combined with a projection that demonstrated continuing losses and a current expectation that the long-lived asset group will be disposed of at a loss before the end of its estimated
useful life. As a result of the discontinuance, the Company considered that a triggering event for impairment review had occurred, due to the current period operating loss and the projection of future losses.

The Company identified the asset group associated with the tunable laser product to include finite-lived intangible assets which
consisted of acquired core technology, noncompete agreement and assembled workforce and fixed assets, consisting of machinery and equipment and leasehold improvements. Based on the review, the Company concluded that the asset group associated with
tunable laser product was fully impaired and an impairment charge of $4.0 million was recognized in the year ended December 31, 2008. The following is a description of the asset group and impairment charge (in thousands):

In September 2008, the Company changed the estimated remaining useful life of acquired technology, and
patents, related to ROADM products, which were associated with its acquisition of OpTun, Inc., from 57 months to 28 months. The change in estimated remaining useful life was made after review of factors such as adverse changes in the
business climate that affected future projections and a current expectation that warranted the

7. Investment and equity accounting

During the first three quarters of 2010, the Company purchased shares of Ignis ASA (Ignis), a Norwegian company traded on the
Oslo exchange (Norway stock exchange) for total consideration of $8.1 million. After such purchases, the Company had an ownership percentage in Ignis of 9%, 17% and 23% as of March 31, June 30 and September 30, 2010,
respectively. During the fourth quarter of 2010, the Companys ownership percentage in Ignis decreased to 19%, due to new shares issued by Ignis.

For periods in which the Company had less than 20% ownership, the cost method of accounting was used to record its investment in Ignis, which involved recording the investment in other long-term assets
and adjusting unrealized gains or losses due to stock price fluctuation within accumulated other comprehensive income. For periods in which the Company had greater than 20% ownership, and considered it had the ability to exert significant influence
over Ignis, the equity method of accounting was used, which involved recording its share of Igniss net income (loss) in other expense, net.

For 2010, the Company recognized a $0.6 million loss relating to its share of Igniss loss. As December 31, 2010, the Company had an investment balance of $12.1 million, including $4.4 million
in unrealized gains and its ownership percentage of Ignis was 19%.

Notes payable

The Company frequently directs its banking partners to issue notes payable to its suppliers in China in exchange for accounts payable. The Companys Chinese subsidiaries banks issue the notes
to vendors and issue payment to the vendors upon redemption. The Company owes the payable balance to the issuing bank. The Companys subsidiaries in China had trade notes payable of $12.7 million and $13.7 million as of December 31,
2010 and 2009, respectively. These notes are unsecured, noninterest bearing and are due approximately six months after issuance.

Short-term loans

The
Companys subsidiaries in China have short-term line of credit facilities from various banking institutions totaling $4.5 million and $14.6 million as of December 31, 2010 and 2009, respectively. These short-term line of credit facilities
have an original maturity date of one year or less and one such facility agreement is secured by the Companys main manufacturing facility in China. Amounts requested by the Company are not guaranteed and are subject to funds and currency
availability. Interest due on the outstanding balance ranges from 4.76% to 5.84% and is charged based on the interest rate set by the Peoples Bank of China. The rate

charged is fixed on the borrowing date for the term of the loan. The short-term line of credit facilities do not require any specific covenants. The weighted average interest rate for short-term
loans outstanding was 5.23% and 5.31% as of December 31, 2010 and 2009, respectively.

Long-term debt

In 2007, the Company entered into a series of three loan and security agreements with a bank for an available credit facility. The term of
each of these agreements was two years. The loan and security agreements are secured by a building located in China owned by the Companys primary subsidiary in China. Interest due on the outstanding balance ranges from 5% to 7% and is charged
based on the interest rate set by the Peoples Bank of China. The rate charged is fixed on the borrowing date for the term of the loan. In 2009, the Company repaid one of the three loans. The remaining two loan and security agreements were
renewed for a term of one year under the original terms and security conditions. These loan and security agreements do not require any specific covenants. As of December 31, 2008, $7.3 million was outstanding under the loan and security
agreements and classified as short-term. The balance was paid in 2009.

In December 2007, the Company entered into a loan and
security agreement with a bank for an available credit facility. The loan and security agreement is secured by substantially all of the Companys U.S. assets, other than intellectual property assets. In December 2008 and December 2009, the loan
and security agreement was amended, increasing the amount of credit available under the facility and extending the term of the lending arrangement through December 2011. The three components of the available credit facility are as follows:



| |  |  | The original loan and security agreement provided a term loan of $1.4 million payable in 12 equal principal installments plus accrued
interest. The term loan bore interest at the LIBOR rate plus a margin ranging from 2.75% to 3.50%, depending on the Companys liquidity ratio. The term loan was paid in full as of December 31, 2008.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | The original loan and security agreement provided for a $6.5 million revolving line of credit, available through December 2009. The December 2009
amendment to the loan and security agreement increased the revolving line of credit to $8.0 million and extended the term through December 2011. Amounts available under the revolving line of credit are reduced by any commercial or stand-by letters
of credit issued by the bank to guarantee a loan for the Companys subsidiaries in China. The maximum amount for which a letter of credit may be issued is $5.0 million. As of December 31, 2010 and 2009, letters of credit for $5.0 million
were outstanding. As of December 31, 2010 and 2009, $3.0 million and $1.5 million were outstanding under the revolving line of credit, respectively. The total available borrowing capacity under this facility was $0.0 million and $1.5 million as
of December 31, 2010 and 2009, respectively.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Amounts outstanding under the revolving line of credit
prior to the December 2009 amendment bore interest at the LIBOR rate plus a margin ranging from 2.50% to 3.25%, depending on the Companys liquidity ratio. The interest rate as of December 31, 2010 was 4.25%.



| |  |  | The original loan and security agreement provided for an $8.5 million credit facility which could be drawn in tranches based on equipment and
software purchases, with the software component not to exceed $2.0 million. Advances were due and payable in 30 equal monthly installments of principal and interest. Amounts outstanding under this facility prior to the December 2009 amendment
bore interest at the LIBOR rate plus a margin ranging from 2.75% to 3.50%, depending on the Companys liquidity ratio. The December 2009 amendment provided that the outstanding balance of $1.6 million is payable in 24 equal monthly installments
through December 2011. No further amounts may be borrowed under the original loan and security agreement.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In
addition, the December 2009 amendment to the loan and security agreement provided an additional $9.5 million in credit based on capital expenditures in the United States. Advances may be drawn in

four tranches and are due and payable in equal monthly installments of principal and interest for terms ranging from 30 to 18 months such that all amounts will be repaid by June 2013. Borrowings
subsequent to the December 2009 amendment will bear interest at the prime referenced rate, which cannot be lower than the LIBOR rate plus 3.75%. The capacity for future borrowing is limited by specified maximum amounts.

As of December 31, 2010 and 2009, $5.8 million and $1.6 million were outstanding, respectively. As of December 31, 2010, amounts
outstanding bear interest at rates ranging from 3.01% to 4.50%. As of December 31, 2010, $3.5 million was available to borrow under this facility.

In connection with the original loan and security agreement, the Company issued a warrant to the lender to purchase 4,482 shares of common stock at an exercise price of $29.00 per share. The warrant was
fully vested upon issuance and is exercisable for seven years from the date of issuance. The estimated fair value of the warrant was measured at issuance using the Black-Scholes option pricing model with the following assumptions: risk-free interest
rate of 3.7%, expected volatility of 77%, dividend yield of 0% and a term of seven years. The fair value of the warrant at issuance of $8,000 is being amortized over the term of the loan and security agreement. As of December 31, 2010, the
warrant had not been exercised.

The loan and security agreement and supplemental amendments requires the Company to maintain
certain financial covenants, including a liquidity ratio, and restricts the Companys ability to incur additional debt or to engage in certain transactions. At December 31, 2010, the Company was in compliance with all of the financial
covenants contained in this agreement.

In December 2007, the Companys primary subsidiary in China entered into a term
loan agreement with a Chinese bank under which the Companys primary subsidiary in China borrowed $5.0 million, due in December 2008. This loan originally bore interest at the banks cost of funds plus 1.00% and interest was payable
quarterly in arrears. The loan is secured by the standby letter of credit described above issued by a U.S. bank. In September 2008, the term loan agreement was amended to extend the due date of the loan to September 2009, and in 2009 was extended
again through February 2010 and to set the interest rate equal to the rate charged by the Peoples Bank of China. As of December 31, 2009, $5.0 million was outstanding under the term loan. In February 2010, the Company repaid the $5.0
million line of credit in full and reborrowed $2.0 million with an interest rate of 3.89%, which was repaid in December 2010. As of December 31, 2010, $5.0 million was available under the line of credit.

The fair value of the short-term loans, notes payable and debt have been calculated
using an estimate of the interest rate the Company would have had to pay on the issuance of liabilities with a similar maturity and discounting the cash flows at that rate. The fair values do not necessarily give an indication of the amount that the
Company would currently have to pay to extinguish any of this debt.

9. Commitments and contingencies

Leases

The Company
leases various facilities under noncancelable operating leases. In December, 2010, the Company entered into a new lease in China through December 2013, with aggregate lease payments of $304,000. As of December 31, 2010, the future minimum
commitments under all operating leases are as follows (in thousands):



|                         |  |   |       | 
|------------------------ |  | - | ----- | 
|Year ending December 31, |  |   |

|2012                     |  |   | 1,501 | 
|2013                     |  |   | 828   | 
|2014                     |  |   | 718   | 
|2015                     |  |   | 698   | 
|Thereafter               |  |   | 1,948 | 
|                         |  |   |       | 
|                         |  | $ | 7,479 | 
|                         |  |   |       | 

Rent expense under the Companys operating leases was $2.0 million, $1.8 million and
$1.8 million for the years ended December 31, 2010, 2009 and 2008, respectively.

Litigation

From time to time, the Company is subject to various claims and legal proceedings, either asserted or unasserted, that arise in the
ordinary course of business. While the outcome of these proceedings and claims cannot be predicted with certainty, the Companys management does not believe that the outcome of any of these currently existing legal matters will have a material
adverse effect on the Companys consolidated financial position, results of operations or cash flow. If an unfavorable ruling occurs in any of the legal proceedings described below, the Companys financial position and results of
operations and cash flows could be negatively affected. The Company accrues for losses related to the litigation when the Companys management considers a potential loss probable and can reasonably estimate such loss in accordance with FASB
requirements. With respect to each of the matters below, the Companys management has determined a potential loss is not probable at this time and, accordingly, no amount has been accrued at December 31, 2010. As the Companys
management continues to monitor these matters, however, its determination could change and it may decide a different reserve is appropriate in the future.

On January 5, 2010, Finisar Corporation, or Finisar, filed a complaint in the United States District Court for the Northern District of California against Source Photonics, Inc., MRV
Communications, Inc., Oplink Communications, Inc. and the Company, or collectively, the co-defendants. In the complaint, Finisar alleged infringement of certain of its U.S. patents arising from the codefendants respective manufacture,
importation, use, sale of or offer to sell certain optical transceiver products. Finisar sought to recover unspecified damages, up to treble the amount of actual damages, together with attorneys fees, interest and costs. Finisar alleged that
at least some of the patents asserted are a part of certain digital diagnostic standards for optoelectronics

transceivers, and, therefore, are being utilized in such digital diagnostic standards. On March 23, 2010, the Company filed an answer to the complaint and counterclaims, asserting two claims
of patent infringement and additional claims asserting that Finisar has violated state and federal competition laws and violated its obligations to license on reasonable and non-discriminatory terms. On May 5, 2010, the court dismissed without
prejudice all co-defendants (including the Company) except Source Photonics, Inc., on grounds that such claims should have been asserted in four separate lawsuits, one against each defendant. This dismissal without prejudice does not prevent Finisar
from bringing a new similar lawsuit against the Company. The Company and Finisar had agreed to suspend their respective claims for a 90 day period and not to refile the originally asserted claims against each other until one or more specified events
occur resulting in the partial or complete resolution of the litigation between Source Photonics and Finisar. On September 10, 2010, Source Photonics and Finisar settled their lawsuit, commencing the suspension period, which ended in December
2010. On January 18, 2011, the Company and Finisar again agreed to suspend their respective claims and not to refile the originally asserted claims against each other until at least 90 days after one or more specified events occur resulting in
the partial or complete resolution of litigation involving the same Finisar patents between Oplink Communications, Inc. and Finisar. At that time, Finisar will be permitted to bring a new lawsuit against the Company if it chooses to do so.

Indemnifications

In the normal course of business, the Company enters into agreements that contain a variety of representations and warranties and provide for general indemnification. The Companys exposure under
these agreements is unknown because it involves claims that may be made against the Company in the future, but have not yet been made. To date, the Company has not paid any claims or been required to defend any action related to its indemnification
obligations. However, the Company may record charges in the future as a result of these indemnification obligations.

Purchase obligations

The Company has purchase obligations with certain suppliers for the purchase of goods and services entered in the ordinary
course of business. As of December 31, 2010, total outstanding purchase obligations were $25.2 million, primarily due within the next 12 months.

Other contingencies

Under Californias recently enacted Global
Warming Solutions Act, the Company will be required to design and install additional pollution control equipment at the San Jose, California, manufacturing plant to reduce perfluorocarbon emissions beginning in 2012. The Company does not expect the
cost additional equipment will have a material impact on its financial position, results of operations or cash flows.

10. Redeemable
convertible preferred stock

Under the Companys Certificate of Incorporation, as amended and restated on
November 29, 2010, the Companys preferred stock is issuable in series. As of December 31, 2010, the Companys Certificate of Incorporation authorized the Company to issue 7,420,000 shares of preferred stock, of which
1,840,000 shares are designated as Series 1 preferred stock, 1,440,000 shares are designated as Series 2 preferred stock, 4,120,000 shares are designated as Series 3 preferred stock and 20,000 shares are designated
as Series X preferred stock.

In May 2008, the Company issued 12,491 shares of Series X preferred stock for
$2,500.00 per share and received cash proceeds of $31.1 million, net of issuance cost of $137,000. In June 2008, the Company issued

49 shares of Series X preferred stock in exchange for 11,352 shares of common stock. In December 2009, the Company issued 3,556 shares of Series X preferred stock for $2,500.00 per share and
received cash proceeds of $8.9 million, net of issuance costs of $24,000. In January 2010, the Company issued 2,401 shares of Series X preferred stock for $2,500.00 per share and received cash proceeds of $6.0 million.

Prior to 2007 and in connection with the issuance of Series 1, 2 and 3 preferred stock, the Company issued warrants for the purchase of
shares of common stock. During the year ended December 31, 2009, warrants to purchase 10,009 shares were exercised. During the year ended December 3, 2010, the remaining 3,508 shares were exercised. As of December 31, 2010, none of
these warrants remaining outstanding.

The following is the activity of the Companys redeemable convertible preferred
stock for the years ended December 31, 2010, 2009 and 2008 (in thousands, except share amounts):

Dividends

The holders
of shares of Series 3 and Series X preferred stock are entitled to receive dividends at the greater of (a) $2.25 per share for Series 3 preferred stock and $225 per share for Series X preferred stock per annum and
(b) the amount of dividends declared pro rata on the common stock and common stock to be issued assuming conversion of all preferred stock, prior and in preference to any declaration or payment of any dividend on the Series 1 preferred
stock, the Series 2 preferred stock or the common stock.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



dividends, on a pari passu basis, at the rate of $3.03275 per share for Series 2 preferred stock and $2.475 per share for Series 1 preferred stock prior and in preference to any
declaration or payment of any dividend on common stock. After the payment of any dividend to the holders of shares of Series 2 preferred stock and Series 1 preferred stock, any further dividend payable, other than in common stock of the
Company, shall be payable to holders of the preferred and common stock pro rata based on the number of shares of common stock held by each, assuming conversion of all preferred stock. Such dividends are payable when, as and if declared by the Board
of Directors, and are not cumulative. As of December 31, 2010, no dividends had been declared.

No dividends can be paid
on the common stock or any other preferred stock unless the holders of Series X and Series 3 preferred stock first or simultaneously receive the amount of the dividends they are entitled to. In addition, the Companys U.S. loan and
security agreement restricts its ability to pay dividends.

Liquidation

In the event of any liquidation, dissolution, change in control or winding up of the Company, whether voluntary or involuntary, the
holders of the Series X preferred stock are entitled to receive, prior and in preference to any distribution of any of the assets of the Company to the holders of the Series 1 preferred stock, Series 2 preferred stock, Series 3
preferred stock and common stock, an amount equal to: (a) in the case of an acquisition transaction, $5,000.00 per share (as adjusted for any stock split, dividend, combination or other recapitalization) plus all declared but unpaid dividends
on such shares or (b) in the case of any liquidation, dissolution of the Company, $2,500.00 per share (appropriately adjusted for any stock split, dividend, combination or other recapitalization) plus all declared but unpaid dividends on such
shares. In the event that upon liquidation or dissolution, the assets and funds of the Company are insufficient to permit the payment to Series X preferred stockholders of the full preferential amounts, then the entire assets and funds of the
Company legally available for distribution are to be distributed ratably among the holders of the Series X preferred stock in proportion to the full preferential amount that each is otherwise entitled to receive.

In the event of any liquidation, dissolution, change in control or winding up of the Company, whether voluntary or involuntary, the
holders of shares of Series 3 preferred stock are entitled to receive, prior and in preference to any distribution of any assets of the Company to the holders of Series 1 preferred stock, Series 2 preferred stock and common stock, an
amount equal to $25.00 per share for each outstanding share of Series 3 preferred stock of the Company (as adjusted for any stock dividends, combinations, or splits) plus any declared but unpaid dividends on such shares. In the event that
upon liquidation or dissolution the assets and funds of the Company are insufficient to permit the payment to Series 3 preferred stockholders of the full preferential amounts, then the entire assets and funds of the Company legally available
for distribution are to be distributed ratably among the holders of the shares of Series 3 preferred stock in proportion to the full preferential amount that each is otherwise entitled to receive. After the foregoing distributions, the
remaining assets will be distributed ratably among the holders of Series 1, 2 and 3 preferred stock and common stock.

In the
event of any liquidation, dissolution, change in control or winding up of the Company, whether voluntary or involuntary, and after the completion of the liquidation preference to Series 3 preferred stockholders, the holders of shares of
Series 1 preferred stock and Series 2 preferred stock are entitled to receive, prior and in preference to any distribution of any assets of the Company to the holders of common stock, an amount equal to $27.50 per share for each
outstanding share of Series 1 preferred stock of the Company (as adjusted for any stock dividends, combinations, or splits) plus any declared but unpaid dividends on such shares and $33.697325 per share for each outstanding share of
Series 2 preferred stock of the Company (as adjusted for any stock dividends, combinations, or splits) plus any declared but unpaid dividends on such shares. In the event that upon liquidation or dissolution the assets and funds of the Company
are insufficient to permit the payment of

Series 1 and Series 2 preferred stockholders of the full preferential amounts, then the entire assets and funds of the Company legally available for distribution are to be distributed
ratably among the holders of the shares of Series 1 preferred stock and Series 2 preferred stock in proportion to the full preferential amount each is otherwise entitled to receive.

The Company has presented Series 1, 2, 3 and X preferred stock outside of deficit in the mezzanine section of the consolidated balance
sheets, as the shares of Series 1, 2, 3 and X preferred stock have a change in control provision which would result in the shares being deemed to be redeemed upon a change in control, which change in control is not solely within the control of the
Company.

The remaining assets, after the above mentioned provisions, will be distributed first, ratably among holders of
preferred stock until (as adjusted for any stock dividends, combinations, or splits): (a) Series 1 preferred stockholders have received an aggregate of $55.00 per share, (b) Series 2 preferred stockholders have received an
aggregate of $67.39465 per share, (c) Series 3 preferred stockholders have received an aggregate of $50.00 per share, and secondly, among the holders of common stock until they have received an aggregate of $51.035 per
share.

Redemption

At any time after May 30, 2011, one or more holders of Series 3 preferred stock or Series X preferred stock that, together with all holders submitting redemption elections, either
(a) own at least 400,000 shares of Series 3 preferred stock in the aggregate at the time of delivery of the redemption notice, (b) owned at least 400,000 shares of Series 3 preferred stock in the aggregate on June 30,
2006, (c) own at least 4,000 shares of Series X preferred stock in the aggregate at the time of delivery of the redemption notice or (d) owned at least 4,000 shares of Series X preferred stock in the aggregate on
June 30, 2008, may redeem up to that number of shares at an amount of $25.00 per share of Series 3 preferred stock and/or $2,500.00 per share of Series X preferred stock (as adjusted for stock splits, stock dividends,
reclassifications or the like) plus all declared but unpaid dividends on the shares in three annual installments of 40%, 40% and 20% of the redemption price, respectively. As a result of the redemption provisions of the Series X and
Series 3 preferred stock, the Company is required to accrete the carrying value of the preferred stock to its redemption value over the period from issuance through redemption date. As a result, during the years ended December 31, 2010,
2009 and 2008, the Company recorded preferred stock accretion of $113,000, $153,000 and $428,000, respectively, as a charge to additional paid-in capital.

On any redemption date, if the funds of the Company are insufficient to redeem the total number of shares of Series 3 preferred stock or Series X preferred stock to be redeemed on such date,
those funds which are legally available will be used to redeem first the maximum possible number of such shares of Series X preferred stock, and second to redeem the maximum possible number of such shares of Series 3 preferred stock. If
shares of more than one redeeming holder are to be redeemed on any redemption date, those funds which are legally available will be used to redeem the maximum possible number of shares, allocated ratably among the holders of such shares to be
redeemed based upon the total redemption price applicable to the shares of Series X preferred stock and Series 3 preferred stock designated to be redeemed by each redeeming holder. The shares of Series X preferred stock and
Series 3 preferred stock not redeemed shall remain outstanding and entitled to all the rights and preferences provided herein. At any time thereafter when additional funds of the Company are legally available for the redemption of shares of
Series X preferred stock and/or Series 3 preferred stock, as applicable, such funds will immediately be used to redeem the balance of the shares which the Company has become obliged to redeem on any redemption date but which it has not
redeemed. Through December 31, 2010, there was no Series X preferred stock or Series 3 preferred stock presented for redemption.

Conversion

Each share of preferred stock, at the option of the holder, is convertible into a number of fully paid shares of common stock as determined by dividing the respective preferred stock issue price by the
conversion price in effect at the time. The initial conversion price of shares of Series 1 preferred stock, Series 2 preferred stock, Series 3 preferred stock and Series X preferred stock is $27.50, $33.697325, $25.00 and $25.00
respectively (as adjusted for any stock dividends, combinations, or splits), and all series are subject to adjustment in accordance with conversion provisions contained in the Companys Certificate of Incorporation. Conversion of the
Series 1, Series 2, Series 3 and Series X preferred stock is automatic immediately upon the earlier of (a) closing of a firm commitment underwritten public offering or (b) the date specified by holders of at least 60%
of the then outstanding shares of preferred stock on an as converted to common stock.

The Series X preferred stock has
additional special conversion features related to a subsequent equity financing and a qualified initial public offering. If the Company issued and sold shares of its equity securities in a single transaction or a series of related transactions
(other than a qualified initial public offering) and received aggregate proceeds from the equity financing of an amount equal to the product of (a) the number of shares of Series X preferred stock then outstanding (adjusted for any stock
split, dividend, combination or other recapitalization with respect to the Series X preferred stock) multiplied by (b) $2,500.00, then the Series X preferred stock would automatically be converted into fully paid and nonassessable
shares of the equity securities issued in the subsequent equity financing. The number of shares of common stock to be issued to holders of Series X preferred stock upon such conversion will be equal to the quotient obtained by dividing
(i) the total number of shares of Series X preferred stock multiplied by $2,500.00 by (ii) 50% of the price per share of the equity securities sold in the subsequent equity financing, rounded to the nearest whole share. The number of
shares of Series X preferred stock, as well as the conversion ratio, is subject to adjustment for any stock split, dividend, combination or other recapitalization with respect to the Series X preferred stock.

If at any time on or before June 30, 2011, the Company issued and sold shares of its common stock in a qualified initial public
offering, the Series X preferred stock will automatically be converted into fully paid and nonassessable shares of common stock upon the completion of the qualified initial public offering. The number of shares of common stock to be issued to
holders of Series X preferred stock upon such conversion shall be equal to the quotient obtained by dividing (a) the total number of shares of Series X preferred stock held by such holders multiplied by $2,500.00 by (b) $6.25,
rounded to the nearest whole share. The number of shares of Series X preferred stock, as well as the conversion ratio, is subject to adjustment for any stock split, dividend, combination or other recapitalization with respect to the
Series X preferred stock.

The Company determined that the modification of the Series X special conversion feature
effected by the amended and restated Articles of Incorporation dated November 29, 2010, did not result in any material incremental value received by the Series X stockholders. As a result, no accounting was deemed necessary upon
modification.

The Company determined that the special conversion feature of the Series X preferred stock providing for
conversion of shares of Series X preferred stock into common stock upon the completion of a qualified initial public offering is a contingent beneficial conversion feature. Upon completion of the initial public offering in the three months end
March 31, 2011, the Company will potentially recognize a charge as a deemed dividend within retained earnings at the time of conversion. In the absence of retained earnings, the Company would record the charge within additional paid-in capital.
As a result, there is no impact on net income (loss) attributable to NeoPhotonics Corporation as the charge is recognized within equity, however, the charge will impact net income (loss) attributable to NeoPhotonics Corporation common stockholders
and basic and diluted net income (loss) per share attributable to NeoPhotonics Corporation common stockholders. For further information, see Note 17.

2004 Stock Option Plan

In March 2004, the Company adopted the 2004 Stock Option Plan (the 2004 Plan) for the benefit of its eligible
employees, consultants and independent directors. The 2004 Plan provides for the issuance of options to purchase common stock. Options granted under the 2004 Plan may be either incentive stock options or nonqualified stock options. Under the terms
of the Plan, awards may be granted at prices not less than 100% of the fair value of the Companys common stock, as determined by the Companys Board of Directors, on the date of grant for an incentive stock option and not less than 85% of
the fair value of the Companys common stock on the date of grant for a non-qualified stock option. Options vest over a period of time as determined by the Board of Directors, generally over a four year period, and expire ten years from date of
grant. Subject to adjustment for certain changes in the Companys capital structure, the maximum aggregate number of shares of common stock that may be issued under the 2004 Plan is 3,010,769.

Stock options granted under the Companys stock option plan provide employee option holders, if approved by the Companys Board
of Directors, the right to elect to exercise unvested options in exchange for restricted common stock, which are subject to a repurchase right held by the Company at the original issuance price in the event the optionees employment is
terminated. Any repurchased shares are not returned to the available share pool for future stock option grants. The shares purchased by the employees pursuant to the early exercise of stock options are deemed to be outstanding. Early exercises of
options are not deemed to be substantive exercises for accounting purposes. Accordingly, amounts received for early exercises are recorded as a liability. These

amounts are reclassified to additional paid-in capital as the underlying options vest. As of December 31, 2010 and 2009, there is a liability related to the issuance of these shares of
$18,000 and $60,000, respectively, which is included in the consolidated balance sheets within accrued and other current liabilities.

The intrinsic value
of options vested and expected to vest and exercisable as of December 31, 2010, is calculated based on the difference between the exercise price and the fair value of the Companys common stock as of December 31, 2010. The intrinsic
value of exercised options during the years ended December 31, 2010, 2009 and 2008 was $144,000, $1,000 and $9,000, respectively, and is calculated based on the difference between the exercise price and the fair value of the Companys
common stock as of the exercise date.

The fair value of all stock options that vested in the year ended December 31,
2010 was $1.2 million.

The weighted-average fair value of options granted was $7.54, $2.94 and $2.87 per share for the years ended
December 31, 2010, 2009 and 2008, respectively.

At December 31, 2010, there was $4.9 million of unrecognized
stock-based compensation expense that will be recognized over the remaining weighted-average period of 3.0 years.

The
Company estimated the fair value of employee stock options using a Black-Scholes valuation model with the following assumptions:



|                                       |  |                          |              |   |      |  |              |      |  |  |              |

|                                       |  | Years Ended December 31, |             
|                                       |  | 2010                     |              |   | 2009 |  |              | 2008 | 
|Weighted-average expected term (years) |  |                          | 6.59         |   |      |  | 6.00         |      |  |  | 5.84         |  
|Weighted-average volatility            |  |                          | 73           | % |      |  | 79           | %    |  |  | 77           | %
|Risk-free interest rate                |  |                          | 2.51%  3.19 | % |      |  | 2.15%  3.12 | %    |  |  | 2.81%  3.45 | %
|Expected dividends                     |  |                          | 0            | % |      |  | 0            | %    |  |  | 0            | %

Expected term.Given the Companys limited historical exercise behavior, the expected term of options granted was determined using the simplified method for years ended December 31, 2009 and 2008. Under this approach, the expected term is
presumed to be the average of the vesting term and the contractual term of the option. The Company granted in-the-money options on January 27, 2010 and March 30, 2010. As a result, the Companys options do not meet the
definition of a plain-vanilla option which is required to estimate expected term using the simplified method. For options granted after December 31, 2009, the expected term was estimated using the Companys
historical exercise behavior and expected future exercise behavior.

Volatility.Since the Companys common stock
is currently not publicly traded and therefore no historical data on volatility of its stock is available, the expected volatility used is based on volatility of similar entities. In evaluating similarity, the Company considered factors such as
industry, stage of life cycle, size, and financial leverage.

Risk-free interest rate. The risk-free rate that the Company uses in the
Black-Scholes option valuation model is based on U.S. Treasury zero-coupon issues with remaining terms similar to the expected term on the options.

Expected dividends.The Company has never declared or paid any cash dividends and does not plan to pay cash dividends in the foreseeable future, and, therefore, used an expected dividend yield of
zero in the valuation model.

The Company is required to estimate forfeitures at the time of grant and revise those estimates
in subsequent periods if actual forfeitures differ from those estimates. The Company uses historical data to estimate pre-vesting option forfeitures and record stock-based compensation expense only for those awards that are expected to vest. All
stock-based payment awards are amortized on a straight-line basis over the requisite service periods of the awards, which are generally the vesting periods. The Companys estimated forfeiture rate was 9.67%, 6.97% and 10.60% for the years ended
December 31, 2010, 2009 and 2008, respectively.

2007 Stock Appreciation Grants Plan

In October 2007, the Company adopted its 2007 Stock Appreciation Grants Plan (the 2007 Plan). The 2007 Plan provides for the
grant of units (stock appreciation units) entitling the holder upon exercise to receive cash in an amount equal to the amount by which the Companys common stock has appreciated in value. Each stock appreciation unit shall entitle a
participant to a cash payment in the amount of the excess of the fair market value of a share of common stock on the exercise date over the fair market value of a share of common stock on the award date.

The total appreciation available to a participant from the exercise of an award is equal to the number of stock appreciation units being
exercised, multiplied by the amount of appreciation per stock appreciation unit. The stock appreciation units granted under this Plan are primarily granted to employees or consultants of the Companys subsidiaries in China.

An award under the plan is not exercisable by any recipient until the earliest to occur of the following: (i) the expiration of the
period of time agreed to between the Companys underwriters and certain stockholders of the Company selected by the underwriters in connection with a public offering of the stock, or (ii) upon the consummation of a change in control, which
means a sale of all or substantially all of the Companys assets, or a merger, consolidation or other capital reorganization or business combination transaction of the Company with or into another corporation or entity. Because neither of these
events have occurred and therefore the employees are not able to exercise their units, no compensation expense has been recognized to date relative to these awards. Upon the occurrence of either of the two events, the Company would recognize
compensation expense and corresponding equal to the number of vested and outstanding stock appreciation units multiplied by the fair value, calculated using the Black-Scholes option pricing model, on that date. In future periods, the Company will
remeasure the fair value (based on the market price of the Companys common stock at the relevant period end) of all vested and outstanding stock appreciation units and adjust compensation expense and corresponding liability accordingly. The
Company will also recognize compensation expense for additional vested stock appreciation units.

The activity of stock
appreciation units is as follows:



|                                                             |  |       |         |

2010 Incentive Plan

The Companys board of directors adopted the 2010 equity incentive plan (the 2010 Incentive Plan) in April 2010, and the Companys stockholders approved this plan in July 2010. The
2010 Incentive Plan will become effective on the next calendar day after the execution and delivery of the underwriting agreement associated with the Companys initial public offering. The 2010 Incentive Plan will terminate on April 13,
2020, unless sooner terminated by the board of directors.

The 2010 Incentive Plan provides for the grant of incentive stock
options, nonstatutory stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance-based stock awards, and other forms of equity compensation, or collectively, stock awards, all of which may be granted
to employees, including officers, and to non-employee directors and consultants. Additionally, the 2010 Incentive Plan provides for the grant of performance cash awards. Incentive stock options may be granted only to employees. All other awards may
be granted to employees, including officers, and to non-employee directors and consultants.

Initially, the aggregate number
of shares of our common stock that may be issued pursuant to stock awards under the 2010 Incentive Plan after the 2010 Incentive Plan becomes effective is 865,420 shares. Then, the number of shares of the Companys common stock reserved for
issuance under the 2010 Incentive Plan will automatically increase on January 1st each year, starting on January 1, 2012 and continuing through January 1, 2020, by 3.5% of the total number of shares of our common stock outstanding on
December 31 of the preceding calendar year, or such lesser number of shares of common stock as determined by the Companys board of directors. The maximum number of shares that may be issued pursuant to the exercise of incentive stock
options under the 2010 Incentive Plan is 8,000,000 shares.

As of December 31, 2010, the 2010 Incentive Plan is not yet
effective and therefore no awards have been granted under this plan.

2010 employee stock purchase plan

The Companys board of directors adopted the 2010 employee stock purchase plan, or ESPP, in April 2010, and the Companys
stockholders approved this plan in July 2010. The ESPP will become effective immediately upon the execution and delivery of the underwriting agreement associated with the Companys initial public offering. The ESPP initially authorizes the
issuance of 342,568 shares of our common stock pursuant to purchase rights granted to employees or to employees of any of our designated affiliates. The number of shares of common stock reserved for issuance will automatically increase on
January 1st each year, starting January 1, 2012 and continuing through January 1, 2020, in an amount equal to the lesser of (1) 3.5% of the total number of shares of common stock outstanding on December 31 of the preceding
calendar year, (2) 600,000 shares of common stock or (3) such lesser number of shares of common stock as determined by the Companys board of directors. The ESPP is intended to qualify as an employee stock purchase plan
within the meaning of Section 423 of the Code.

The ESPP will be implemented through a series of offerings of purchase
rights to eligible employees. Employees may participate through payroll deductions of up to 15% of their earnings. Unless otherwise determined by the Companys board of directors, common stock will be purchased for participating employees at a
price per share equal to the lower of (a) 85% of the fair market value of a share of the Companys common stock on the first date of an offering, or (b) 85% of the fair market value of a share of the Companys common stock on the
date of purchase.

As of December 31, 2010, the ESPP is not yet effective and therefore no rights have been granted and
no shares of common stock have been purchases pursuant to this plan.

The net valuation allowance decreased by $0.2 million during the year ended December 31, 2010,
primarily due to the decrease in state deferred tax assets and expired net operating losses.

As of December 31, 2010,
the Company had net operating loss, or NOL, carryforwards for federal and state tax purposes of $138.4 million and $47.3 million, respectively. If not utilized, the federal and state net operating losses expire starting in 2011. The
Company also had federal and state research credit carryovers of $2.4 million and $5.4 million, respectively. The federal research credits expire beginning in 2018. The state research credit has no expiration. Utilization of the NOL and
tax credit carryforwards are subject to a substantial annual limitation due to the ownership change limitations provided by the Internal Revenue Code of 1986, as amended, and similar state provisions. The annual limitation may result in the
expiration of NOL and tax credit carryforwards before utilization.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS(Continued)



The deferred tax assets listed above do not include NOL carryforwards that are expected
to expire unutilized as a result of existing ownership changes.

The Company has no present intention of remitting
undistributed earnings of foreign subsidiaries, and, accordingly, no deferred tax liability has been established relative to these earnings. Determination of the amount of unrecognized deferred tax liability on these undistributed earnings is not
practicable. As of December 31, 2010, the Companys undistributed earnings of foreign subsidiaries was $11.4 million.

In 2010 and 2009, certain of the Companys subsidiaries benefited from various tax incentives, including tax holidays and reduced
tax rates ranging from 15% to 20%, for operating in special economic zones or for engaging in certain qualifying business activities in China. The Company realized benefits from the reduced tax rate for the years ended December 31, 2010 and
2009 as follows (in thousands):

Prior to January 1, 2008, entities established in China were generally subject to a 30% state and 3%
local enterprise income tax rate. In accordance with the China Income Tax Law for Enterprises with Foreign Investment and Foreign Enterprises, effective through December 31, 2007, the Companys China subsidiaries enjoyed preferential
income tax rates. Effective January 1, 2008, the China Enterprise Income Tax Law, or the EIT law, imposes a single uniform income tax rate of 25% on all China enterprises, including foreign invested enterprises, and eliminates or modifies most
of the tax exemptions, reductions and preferential treatment available under the previous tax laws and regulations. As a result, the Companys China subsidiaries may be subject to the uniform income tax rate of 25% unless they are able to
qualify for preferential status. Currently, they have qualified for a preferential 15% tax rate that is available for new and high technology enterprises. The preferential rate applies to 2010, 2009 and 2008. The Company will reapply for the
preferential rate for 2011. If approved, the rate will remain at 15%, otherwise, the rate will be 24% for 2011 and 25% thereafter.

Tax effects of a position are recognized only if it is more likely than not to be sustained based solely on its technical merits as of the reporting date. At December 31, 2010, the
Company had $5.1 million of unrecognized tax benefits, $169,000, of which would affect its effective tax rate if recognized.

The Company recognizes interest and penalties related to uncertain tax positions, if any, as a component of
its income tax provision. For all years presented, the Company recognized no interest and penalties related to uncertain tax positions, as the uncertain tax position balances offset deferred tax assets, which are subject to a valuation allowance.

Uncertain tax positions relate to potential obligations related to permanent establishment in the Companys global
subsidiaries and to the determination of the research and experimental tax credit. The Company does not consider that it is reasonably possible that there will be a material change in its uncertain tax positions in the next 12 months.

The Company files income tax returns in the U.S federal jurisdiction and various states and foreign jurisdictions. As of
December 31, 2010, the Companys federal returns for the year ended December 31, 2007 through the current period and most state returns for the year ended December 31, 2006 through the current period are still open to
examination. In addition, all of the net operating losses and research and development credit carryforwards that may be utilized in future years are still subject to examination. The Company is not currently subject to U.S. federal, state and local,
or non-U.S. income tax examinations by any tax authorities.

14. Noncontrolling interests

From February 2005 through March 2006, the Company acquired substantially all of the outstanding shares of NeoPhotonics (China) Co., Ltd.
(NeoPhotonics China), a Company based in China that is a manufacturer of active optoelectronics components, optical subassemblies and transceivers. The remaining 0.4% of the outstanding shares were held by a noncontrolling shareholder and therefore
represented a noncontrolling interest in NeoPhotonics China. In April 2010, the Company acquired the remaining 0.4% of outstanding shares of NeoPhotonics China for $0.1 million. After the transaction, the Company owned 100% of NeoPhotonics China. As
of December 31, 2008, NeoPhotonics China owned 90% of the shares of Shenzhen Photon Broadband Technology Co., Ltd. (Broadband), a Company based in China. In March 2009, NeoPhotonics China acquired the remaining 10% of outstanding shares of
Broadband for $0.7 million, which was $0.3 million greater than the carrying value of the noncontrolling interest and therefore, the transaction was recorded as a reduction to NeoPhotonics Chinas noncontrolling interest for the carrying amount
and a reduction to additional paid-in capital for the excess amount paid. After the transaction, NeoPhotonics China owned 100% of Broadband.

As of December 31, 2009, the Company had a joint venture interest in Archcom, whereby the Company owned 55% of the joint venture and Archcom Technology Limited owned 45% of the joint venture. The
joint venture was consolidated, with 45% representing a noncontrolling interest in Archcom. In November 2009, the Company entered into an agreement with Archcom Technology Limited to sell its 55% ownership interest, including certain equipment held
by the joint venture, for $1.1 million. Half of the amount, or $550,000, was paid

to the Company in December 2009. In March 2010, the Company received foreign regulatory approval for completion of the sale of its ownership interest in Archcom. The Company received the
remaining $550,000 of the sale consideration upon completion of the sale on March 31, 2010.

As of December 31,
2010, the Company has no noncontrolling interests in the consolidated balance sheet.

15. Segment reporting

16. Restructuring

During the third quarter of 2008, the Company initiated a restructuring plan as part of a companywide cost saving initiative aimed to reduce operating costs primarily by moving manufacturing operations
from the United States to China to capitalize on synergies and operational efficiencies. The Company recorded $1.3 million of expense for severance costs resulting from involuntary termination of 170 employees located in the United States and China
and $126,000 of expense related to facility closure. The Companys restructuring charges are presented as a separate line within operating expense in the consolidated statement of operations. The following table summarized the restructuring
activity for the periods presented (in thousands):

17. Subsequent events (unaudited)

In February 2011, the Company completed its initial public offering of 8,625,000 shares of its common stock, including the full
underwriters over-allotment option, at a public offering price of $11.00 per share. Cash proceeds from the initial public offering were approximately $88.2 million, prior to deducting offering expenses.

In connection with the closing of the initial public offering, all of the shares of Series 1, Series 2 and Series 3 preferred stock
outstanding automatically converted into 6,639,513 shares of common stock on a 1-for-1 basis and all of the shares of Series X preferred stock outstanding automatically converted into 7,398,976 shares of common stock on a 400-for-1 basis. The Series
X preferred stock contained a special conversion feature which was contingent upon completion of an initial public offering. The beneficial conversion feature is measured as the difference between the offering price of $11 per share and the
conversion amount of $6.25 per share. At the closing of the initial public offering, the beneficial conversion feature was recorded to additional paid-in-capital and will represent a deemed dividend in calculating net income (loss) attributable to
NeoPhotonics Corporation common stockholders, for the first fiscal quarter ending March 31, 2011. For 2010 and 2009, pro forma net income (loss) per share attributable to NeoPhotonics Corporation common stockholders, which assumes all preferred
stock are converted to common stock at the beginning of each year on as converted basis, are as follows:

As of the close of the Companys initial public offering, there were 115,597 fully vested stock
appreciation units outstanding that become exercisable upon the expiration of the lock-up period associated with the Companys initial public offering. Due to the contingent nature of these awards, as of December 31, 2010, no compensation
expense had been recognized. Upon completion of the Companys initial public offering, the Company recognized compensation expense representing the number of vested stock appreciation units at that date, multiplied by the fair value of the
award, using the Black-Scholes option pricing model, which will be included in the results of operations for the first fiscal quarter ending March 31, 2011. Additional compensation expense will be recognized in this quarter and going forward,
based on additional vesting of stock appreciation units and changes in the fair value of the vested stock appreciation units. The fair value of the stock appreciation units is based, in part, on the value of the Companys common stock and
therefore can vary significantly.

In connection with the closing of the Companys initial public offering and executive
of the associated underwriting agreement, the Companys 2010 Equity Incentive Plan and 2010 ESPP Plan became effective and shares authorized for issuance under the 2004 Plan were cancelled (except for those shares reserved for issuance upon
exercise of outstanding stock options).

|(1) | In the three months ended December 31, 2010, the Company recorded out-of-period adjustments to reduce deferred tax assets by $215,000 and to reduce inventory by
$243,000. The correction of these errors resulted in a reduction to the Companys net income of $458,000 for the three months ended December 31, 2010. The resulting errors increased net income for the three months ended September 30, June 30
and March 31, 2010 by $105,000, $118,000 and $20,000, respectively. The resulting errors did not have a material impact to the 2009 quarters.

|ITEM 9A. | CONTROLS AND PROCEDURES
|-------- | -----------------------

Evaluation of Disclosure Controls and Procedures

Our management, with the
participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2010. The term disclosure controls and procedures, as defined in
Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under
the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SECs rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure
that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the companys management, including its principal executive and principal financial
officers, as appropriate to allow timely decisions regarding required disclosure. Based on the evaluation of our disclosure controls and procedures as of December 31, 2010, our chief executive officer and chief financial officer concluded that,
as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Management
recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of
possible controls and procedures.

Managements Annual Report on Internal Control Over Financial Reporting

This Annual Report on Form 10-K does not include a report of managements assessment regarding internal control over financial
reporting or an attestation report of our registered public accounting firm as permitted in this transition period under the rules of the SEC for newly public companies.

Changes in Internal Control over Financial Reporting

There were no changes
in our internal control over financial reporting identified in managements evaluation pursuant to Rules 13a-15(d) or 15d-15(d) of the Exchange Act during the quarter ended December 31, 2010 that materially affected, or are reasonably
likely to materially affect, our internal control over financial reporting.
