PART I

Overview

We provide advanced optical packaging and precision optical, electro-mechanical and electronic manufacturing services to original equipment manufacturers (“OEMs”) of complex products such as optical communication components, modules andsub-systems, industrial lasers, automotive components, medical devices and sensors. We offer a broad range of advanced optical and electro-mechanical capabilities across the entire manufacturing process, including process design and engineering, supply chain management, manufacturing, complex printed circuit board assembly, advanced packaging, integration, final assembly and test.testing. Although we focus primarily onlow-volume production of a wide variety of high complexity products, which we refer to as“low-volume,high-mix,” we also have the capability to accommodate high-volume production. Based on our experience with and positive feedback we have received from our customers, we believe we are a global leader in providing these services to the optical communications, industrial lasers and automotive markets.

Our customer base includes companies in complex industries that require advanced precision manufacturing capabilities, such as optical communications, industrial lasers, automotive and sensors. Our customers in these industries support a growing number ofend-markets, including automotive, biotechnology, communications, materials processing, medical devices, metrology and semiconductor processing. Our total revenues for the year ended June 28, 2019 (“fiscal year 2019”) increased by $212.4 million, or 15.5%, from $1.37 billion for the year ended June 29, 2018 (“fiscal year 2018”) decreased by $48.6 million, or 3.4%, from $1.42 billion for the year ended June 30, 2017 (“fiscal year 2017”) to $1.37$1.58 billion for fiscal year 2018.2019. Our revenues from lasers, sensors and other markets as a percentage of total revenues increaseddecreased from 22.0% for27.1% in fiscal year 20172018 to 27.1% for25.2% in fiscal year 2018,2019, while our revenues from optical communications products as a percentage of total revenues have decreasedincreased from 78.0% for72.9% in fiscal year 20172018 to 72.9% for74.8% in fiscal year 2018.2019.

In many cases, we are the sole outsourced manufacturing partner used by our customers for the products that we produce for them. The products that we manufacture for our OEM customers include:

We also design and fabricate application-specific crystals, lenses, prisms, mirrors, laser components and substrates (collectively referred to as “customized optics”) and other custom and standard borosilicate, clear

fused quartz, and synthetic fused silica glass products (collectively referred to as “customized glass”). We incorporate our customized optics and glass into many of the products we manufacture for our OEM customers, and we also sell customized optics and glass in the merchant market.

We believe we offer differentiated manufacturing services through our optical and electro-mechanical process technologies and our strategic alignment with our customers. Our dedicated process and design engineers, who have a deep knowledge in materials sciences and physics, are able to tailor our service offerings to accommodate our customers’ complex engineering assignments. Our range of capabilities, from the design of customized optics and glass through process engineering and testing of finished assemblies, provides us with a knowledge base that we believe often leads to improvements in our customers’ product development cycles, manufacturing cycle times, quality and reliability, manufacturing yields and end product costs. We offer an efficient, technologically advanced and flexible manufacturing infrastructure designed to enable the scale production oflow-volume,high-mix products, as well as high-volume products. We specialize in complex prototype and new product introduction services, with specialized resources to meet customers’ quick-turn printed circuit board assembly (“PCBA”) and early stage manufacturing requirements. We have a dedicated engineering team to support the advanced optical packaging needs of our customers’ cutting edge products, which allows them to accelerate development andtime-to-market for such products. We often provide a“factory-within-a-factory” manufacturing environment to safeguard our customers’ intellectual property by physically segregating certain key employees and manufacturing space from the resources we use for other customers. We also provide our customers with a customized software platform to monitor all aspects of the manufacturing process, enabling our customers to remotely access our databases to monitor yields, inventory positions,work-in-progress status and vendor quality data in real time. We believe there is no other manufacturing services provider with a similar breadth and depth of optical and electro-mechanical engineering and process technology capabilities that does not directly compete with its customers in theirend-markets. As a result, we believe we are more closely aligned and better able to develop long-term relationships with our customers than our competitors.

We are organized and operate in a single segment. See Note 20, Business segments and geographic information of Notes to Consolidated Financial Statements in Part II, Item 8 of this Annual Report onForm 10-K, which is incorporated herein by reference.

As of June 29, 2018,28, 2019, our facilities comprised approximately 2.0 million total square feet, including approximately 0.2 million square feet of office space and approximately 1.8 million square feet devoted to manufacturing and related activities, of which approximately 0.8 million square feet are clean room facilities. Of the aggregate square footage of our facilities, approximately 1.5 million square feet are located in Thailand and the remaining balance is located in the People’s Republic of China (“PRC” or “China”), the United Kingdom, the United States and the Cayman Islands. See Part I, Item 2. Properties of this Annual Report on Form10-K.

Industry Background

Optical Communications

Many optical communications OEMs have reduced internal manufacturing capacity and transitioned to alow-cost and more efficient manufacturing base. By outsourcing production to third parties, OEMs are better able to concentrate their efforts and resources on what they believe are their core strengths, such as research and development, and sales and marketing. Additionally, outsourcing production often allows OEMs to reduce product costs, improve quality, access advanced process design and manufacturing technologies and achieve acceleratedtime-to-market andtime-to-volume production. The principal barrier to the trend towards outsourcing in the optics industry has been the shortage of third-party manufacturing partners with the necessary optical process capabilities and robust intellectual property protection.

Demand for optical communications components and modules is influenced by the level and rate of development of optical communications infrastructure and carrier and enterprise network expansion, as well as

Industrial Lasers, Sensors and Others

The optical and electro-mechanical process technologies used in the optical communications market also have applications in other similarly complexend-markets that require advanced precision manufacturing capabilities, such as automotive, industrial lasers, medical devices, and sensors. These markets are substantially larger than the optical communications components and modules market. Growth in the industrial lasers, medical, and sensors markets is expected to be driven by demand for:

Outsourcing of production by industrial laser and sensor OEMs has historically been limited. We believe industrial laser and sensor OEMs are increasingly recognizing the benefits of outsourcing that OEMs in other industries, such as optical communications, have been able to achieve.

Our Competitive Strengths

We believe we have succeeded in providing differentiated services to the optical communications, industrial lasers, medical, and sensors industries due to our long-term focus on optical and electro-mechanical process technologies, strategic alignment with our customers and our commitment to total customer satisfaction. More specifically, our key competitive strengths include:

Our Growth Strategy

The key elements of our growth strategy are to:

In March 2018, we began laying the groundwork for a new NPI facility in Israel, where we expect to continue our proven model of providing local NPI services, helping our customers with design for manufacturability, and then transferring those programs to Thailand for volume manufacturing.

Service Offerings

We offer integrated precision optical, electro-mechanical, and electronic manufacturing services and customized optics and glass fabrication services for our OEM customers.

Precision Optical, Electro-Mechanical, and Electronic Manufacturing Services

Process Design and Engineering

We continuously analyze our customers’ product designs for cost and manufacturability improvements. We perform detailed design for manufacturability studies and design of experiments to assist in optimizing a product’s design for the lowest cost possible without compromising the quality specifications of form, fit and function. In the case of a new product design, we may assist in assembling one or more prototype products using the same production line and the same engineering and manufacturing teams that would be used for product qualification and volume production. We often transfer production from a customer’s internal prototype or production lines to our own facilities, requiring a copy-exact: the setup of a production process identical to the one used by our customer to minimize the number of variables and expedite qualification.

Advanced Optical Packaging

We have a dedicated team of experienced engineers supporting our advanced optical packaging development capabilities. These highly qualified engineers work closely with our customers to understand the

variety of mounting and assembly technologies, including SMT, PTH and ACT,press-fit, and other connection processes that are focused on miniaturization and increasing the density of component placement on printed circuit boards. These technologies, which support the needs of our customers to provide greater functionality in smaller products, include chip-scale packaging, ball grid array, direct chip attach and high density interconnect. We performin-circuit, functional and environmental testing of printed circuit board assemblies to verify all components are properly inserted, attached and the electrical circuits are complete, and that the board or assembly operates in accordance with its final design and manufacturing specifications.

Dedicated New Product Introduction

We are committed to providing NPI capabilities designed to ensure that our customers’ products get to market as quickly as possible.Co-locating strong engineering services in process design, prototyping, design for manufacturability (“DFM”) and test at these locations gives customers asa full suite of NPI services for quick-turn PCBA tobox-build to full system assembly. Stringent IP protection protocols are strictly enforced throughout the entire process, safeguarding our customers’ intellectual property. Our NPI sites are outfitted withstate-of-the-art production equipment that mirrors the equipment used in ourlow-cost manufacturing facilities, ensuring a fast, smooth transition to alow-cost production environment once the product is qualified.

Qualifications

Production line and environmental qualifications require a variety of process engineering and technical skills, and the use of specialized equipment. Many of the products that we produce for our customers require extensive environmental and reliability qualification involving, in some cases, a three to six months or longer duration prior to volume production. The qualification phase may include a customer’s certification of a production line or process and one or a series of qualification tests for mechanical integrity and environmental endurance as specified by an industry standards organization, such as Telcordia for telecommunication equipment. We have extensive expertise in the planning, executing, troubleshooting and ultimate success of these qualifications and testing environments, which provides our customers a higher likelihood of completing these qualifications in a timely fashion.

Continuous Improvement and Optimization

Once we have completed the qualification phase and stabilized production yields, we shift our focus to cost and quality optimization. This requires a close working relationship with our customer to optimize processes and identify alternative sources for materials to improve efficiency, yields and cost. Design and process improvements may include reducing the number of parts, simplifying the assembly process, eliminatingnon-value add operations, using standard materials and optimizing manufacturing lines.

Supply Chain and Inventory Management

Our expertise in supply chain and materials management often allows us to further reduce costs and cycle times for our customers. Our procurement and materials management services include planning, purchasing,

directly integrated with our test system and enterprise resource planning (“ERP”) database allowing us to respond to any process deviations in real time. We work with customers to develop product-specific test strategies. We also provide a variety of test management services, including material and process testing and reliability testing. In addition to providing yield, manufacturing data tracking and other information, our data tracking system also performs process route checking to ensure that the products follow correct process steps, and the test results meet all specified criteria. Our test capabilities include traditional PCBA testing, mechanical testing and optical testing, which includes parametric testing, such as insertion loss, return loss and extinction ratio, and functional testing (e.g., bit error ratio).

Customized Glass and Crystal Optics Fabrication

We design and fabricate our own customized glass and crystal optics, which are core components of the higher level assemblies that we manufacture for our customers. Our fabrication facilities are located in Fuzhou, China and Mountain Lakes, New Jersey. Our customized glass and crystal optics products include the following:

Technology

Based on our experience with customers and our qualitative assessment of our capabilities, we believe we provide a broader array of process technologies to the optics industry than any other manufacturing services provider. We also continue to invest in customized optics and glass technology including in the areas of crystal growth, crystal and glass processing, optical coating, polishing and lapping, optical assemblies and precision glass drawing. We intend to continue to increase our process engineering capabilities and manufacturing

2019 and 2018, and fiscal year 2017, we had one customer, Lumentum Operations LLC, that contributed 10% or more of our total revenues. This customer accounted for 16% and 17%revenues, with 20% of our total revenues during the respectivein fiscal years.year 2019 and 16% in fiscal year 2018.

The production of optical devices is characterized by a lengthy qualification process. In particular, the qualification and field testing of the products that we produce for our customers may take three to six months or longer to complete. Generally, we must qualify our production process with our customers, and the products that we manufacture must also meet the product quality requirements of our customers’ customers. While most of our customers do not purchase our services until they qualify the services and satisfactorily complete factory audits and vendor evaluations, we typically produce a test run of their products to demonstrate that the products we produce will meet their qualification standards in advance of receiving an order. As part of this process, our engineers work closely with the customer’s design and procurement teams. We believe that the rigorous product transfer and qualification processes, and the close relationships that we develop with our customers during those processes, results in greater visibility into product life cycles and longer-term customer engagements.

Backlog

We are substantially dependent on orders we receive and fill on a short-term basis. Although we often receive a12-month forecast from our customers, our customer contracts do not provide any assurance of future sales, and sales are typically made pursuant to individual purchase orders that have short lead times and are subject to revision or cancellation. Because of the possibility of changes in delivery or acceptance schedules, cancellations of orders, returns or price reductions, we do not believe that backlog is a reliable indicator of our future revenues.

Suppliers of Raw Materials

Our manufacturing operations use a wide variety of optical, semiconductor, mechanical and electronic components, assemblies and raw materials. We generally purchase materials from our suppliers through standard purchase orders, as opposed to long-term supply agreements. We rely on sole-source suppliers for a number of critical materials. Some of these sole-source suppliers are small businesses, which presents risks to us based on their financial health and reliability, which we continually monitor. We have historically experienced supply shortages resulting from various causes, including reduced yields by our suppliers, which have prevented us from manufacturing products for our customers in a timely manner. While we continually undertake programs to strengthen our supply chain, we are experiencing, and expect for the foreseeable future to continue to experience, strain on our supply chain, as well as periodic supplier problems. We have incurred, and expect to continue to incur for the foreseeable future, costs to address these problems.

Quality

We have an extensive quality management system that focuses on continual process improvement and achieving high levels of customer satisfaction. We employ a variety of enhanced statistical engineering

Additionally, we are required to register with the FDA and other regulatory bodies and are subject to continual review and periodic inspection for compliance with various regulations, including testing, quality control and documentation procedures. We hold the following additional certifications: ANSI ESD S20.20 for facilities and manufacturing process control, in compliance with ESD standard; Transported Asset Protection Association, or TAPA, for Logistic Security Management System; andCSR-DIW for Corporate Social Responsibility in Thailand. In the European Union, we are required to maintain certain ISO certifications in order to sell our precision optical, electro-mechanical and electronic manufacturing services and we must undergo periodic inspections by regulatory bodies to obtain and maintain these certifications.

In addition to these standards, we are committed to the deployment of sustainable manufacturing, lean initiatives, and continuous improvement throughout our operations. The implementation of lean manufacturing initiatives helps improve efficiency and reduce waste in the manufacturing process in areas such as inventory on hand, set up times, and floor space and the number of people required for production, while Kaizen and Six Sigma ensures continuous improvement by reducing process variation.

Competition

Although the manufacturing services market is highly competitive, we believe that there are significant barriers to entry in our existing and target markets, including lengthy sales cycles, the need to demonstrate complex precision optical and electro-mechanical engineering and manufacturing capabilities to a prospective customer and the ability to protect a customer’s intellectual property.

Our overall competitive position depends upon a number of factors, including:

these licenses is limited to the duration of the underlying supply or manufacturing agreement. To meet the demands of certain customers, we created afactory-within-a-factory manufacturing environment that physically separates the manufacturing sites from one another. Some customers, for example, demand anonymity at our facilities while other customers require additional security measures such as biometric devices to safeguard their segregated manufacturing areas.

We regard our own manufacturing process technologies and customized optics and glass designs as proprietary intellectual property. We own any process engineering technology independently developedin-house by our technical staff. As part of our manufacturing services, to the extent we utilize our own manufacturing process technologies in the manufacture of our customers’ products, we grant our customers a royalty-free license to these process engineering technologies for the purpose of allowing our customers to make their products. Any process engineering or other improvements that we develop in connection with the improvement or optimization of a process for the manufacturing of a customer’s products are immediately assigned to that customer. To protect our proprietary rights, we rely largely upon a combination of trade secrets,non-disclosure agreements and internal security systems. Historically, patents have not played a significant role in the protection of our proprietary rights. Nevertheless, we currently have a relatively small number of solely-owned andjointly-held PRC patents in various customized optic technologies with expiration dates between 2022 and 2034. We believe that both our evolving business practices and industry trends may result in the continued growth of our patent portfolio and its importance to us, particularly as we expand our business.

Environmental Regulation

We are subject to a variety of international and U.S. laws and other legal requirements relating to the use, disposal, cleanup of and human exposure to hazardous materials. To date, such laws and regulations have not materially affected our business. We do not anticipate any material capital expenditures for environmental control facilities for the foreseeable future. While to date we are not aware of any material exposures, there can be no assurance that environmental matters will not arise in the future or that costs will not be incurred with respect to sites as to which no problem is currently known.

Social Responsibility

Our corporate social responsibility practices focus on creating better social, economic and environmental outcomes for all stakeholders in the global electronics supply chain. These outcomes include: improved conditions for workers, increased efficiency and productivity for customers and suppliers, economic development, and a clean environment for our communities. We are committed to implementing programs that focus on driving continuous improvements in social, ethical, and environmental compliance throughout all of our global operating units in accordance with our Code of Business Conduct. As a guide to achieve this end, we look at principles, policies and standards as prescribed by the Responsible Business Alliance (“RBA”), formerly the Electronics Industry Citizenship Coalition, (“EICC”), an association of global electronics companies whose mission is to enable companies to improve the social and environmental conditions in the global supply chain. Fabrinet is a full member of the EICC.RBA.

Employees

As of June 29, 2018,28, 2019, we employed approximately 10,57911,670 full-time employees worldwide, including approximately 10,27111,372 employees in manufacturing operations and 308298 employees in business development and general and administrative functions. None of our employees are represented by a labor union. We have not experienced any work stoppages, slowdowns, or strikes. We consider our relations with our employees to be positive.

Investing in our ordinary shares involves a high degree of risk. You should carefully consider the following risks as well as the other information contained in this Annual Report on Form10-K, including our consolidated financial statements and the related notes, before investing in our ordinary shares. The risks and uncertainties described below are not the only ones that we may face. Additional risks and uncertainties of which we are unaware, or that we currently deem immaterial, also may become important factors that affect us or our ordinary shares. If any of the following risks actually occur, they may harm our business, financial condition and operating results. In this event, the market price of our ordinary shares could decline and you could lose some or all of your investment.

Risks Related to Our Business

Our sales depend on a small number of customers. A reduction in orders from any of these customers, the loss of any of these customers, or a customer exerting significant pricing and margin pressures on us could harm our business, financial condition and operating results.

We have depended, and will continue to depend, upon a small number of customers for a significant percentage of our total revenues. During fiscal yearyears 2019 and 2018, and fiscal year 2017, we had one customer, Lumentum Operations LLC, that contributed 10% or more of our total revenues. This customer accounted for 16% and 17%revenues, with 20% of our total revenues during the respectivein fiscal years.year 2019 and 16% in fiscal year 2018. Dependence on a small number of customers means that a reduction in orders from, a loss of, or other adverse actions by any one of these customers would reduce our revenues and could have a material adverse effect on our business, financial condition and operating results.

Further, our customer concentration increases the concentration of our accounts receivable and our exposure to payment default by any of our key customers. Many of our existing and potential customers have substantial debt burdens, have experienced financial distress, or have static or declining revenues, all of which may be exacerbated by adverse conditions in the credit markets, continual uncertainty in global economies, the impact of the U.S.-China trade dispute, and the impactsimpact of Brexit. Certain of our customers have gone out of business, declared bankruptcy, been acquired, or announced their withdrawal from segments of the optics market. We generate significant accounts payable and inventory for the services that we provide to our customers, which could expose us to substantial and potentially unrecoverable costs if we do not receive payment from our customers.

RelianceOur reliance on a small number of customers gives thoseour customers substantial purchasing power and leverage in negotiating contracts with us. In addition, although we enter into master supply agreements with our customers, the level of business to be transacted under those agreements is not guaranteed. Instead, we are awarded business under those agreements on aproject-by-project basis. Some of our customers have at times significantly reduced or delayed the volume of manufacturing services that they order from us. If we are unable to maintain our relationships with our existing significant customers, our business, financial condition and operating results could be harmed.

Consolidation in the markets we serve could harm our business, financial condition and operating results.

Consolidation in the markets we serve has resulted in a reduction in the number of potential customers for our services. For example, in March 2018, Lumentum Holdings Inc. and Oclaro, Inc., both of which are our customers,Cisco entered into an agreement for Lumentumin July 2019 to acquire Oclaro.Acacia Communications, Lumentum Holdings Inc. completed its acquisition of Oclaro, Inc. in December 2018, andII-VI Incorporated entered into an agreement in November 2018 to acquire Finisar Corporation. In some cases, consolidation among our customers has led to a reduction in demand for our services as customers acquired the capacity to manufacture productsin-house.

Consolidation among our customers and their customers maywill continue and mayto adversely affect our business, financial condition and operating results in several ways. Consolidation among our customers and their

customers may result in a smaller number of large customers whose size and purchasing power give them increased leverage that may result in, among other things, decreases in our average selling prices. In addition to pricing pressures, this consolidation may also reduce overall demand for our manufacturing services if customers obtain new capacity to manufacture productsin-house or discontinue duplicate or competing product lines in order to streamline operations. If demand for our manufacturing services decreases, our business, financial condition and operating results could be harmed.

If the optical communications market does not expand as we expect, our business may not grow as fast as we expect, which could adversely impact our business, financial condition and operating results.

Revenues from optical communications products represented 74.8% and 72.9% of our total revenues for fiscal year 2019 and fiscal year 2018, respectively. Our future success as a provider of precision optical, electro-mechanical and electronic manufacturing services for the optical communications market depends on the continued growth of the optics industry and, in particular, the continued expansion of global information networks, particularly those directly or indirectly dependent upon a fiber optic infrastructure. As part of that growth, we anticipate that demand for voice, video, and other data services delivered over high-speed connections (both wired and wireless) will continue to increase. Without network and bandwidth growth, the need for enhanced communications products would be jeopardized. Currently, demand for network services and for high-speed broadband access, in particular, is increasing but growth may be limited by several factors, including, among others: (1) relative strength or weakness of the global economy or certain countries or regions, (2) an uncertain regulatory environment, and (3) uncertainty regarding long-term sustainable business models as multiple industries, such as the cable, traditional telecommunications, wireless and satellite industries, offer competing content delivery solutions. The optical communications market also has experienced periods of overcapacity, some of which have occurred even during periods of relatively high network usage and bandwidth demands. If the factors described above were to slow, stop or reverse the expansion in the optical communications market, our business, financial condition and operating results would be negatively affected.

Our quarterly revenues, gross profit margins and operating results have fluctuated significantly and may continue to do so in the future, which may cause the market price of our ordinary shares to decline or be volatile.

Our quarterly revenues, gross profit margins, and operating results have fluctuated significantly and may continue to fluctuate significantly in the future. For example, any of the risks described in this “Risk Factors” section and, in particular, the following factors, could cause our quarterly and annual revenues, gross profit margins, and operating results to fluctuate from period to period:

Therefore, we believe thatquarter-to-quarter comparisons of our operating results may not be useful in predicting our future operating results. You should not rely on our results for one quarter as any indication of our future performance. Quarterly variations in our operations could result in significant volatility in the market price of our ordinary shares.

If we are unable to continue diversifying our precision optical and electro-mechanical manufacturing services across other markets within the optics industry, such as the semiconductor processing, biotechnology, metrology and material processing markets, or if these markets do not grow as fast as we expect, our business may not grow as fast as we expect, which could adversely impact our business, financial condition and operating results.

We intend to continue diversifying across other markets within the optics industry, such as the semiconductor processing, biotechnology, metrology, and material processing markets, to reduce our dependence on the optical communications market and to grow our business. Currently, the optical communications market contributes the significant majority of our revenues. There can be no assurance that our efforts to further expand and diversify into other markets within the optics industry will prove successful or that these markets will continue to grow as fast as we expect. In the event that the opportunities presented by these markets prove to be less than anticipated, if we are less successful than expected in diversifying into these markets, or if our margins in these markets prove to be less than expected, our growth may slow or stall, and we may incur costs that are not offset by revenues in these markets, all of which could harm our business, financial condition and operating results.

We face significant competition in our business. If we are unable to compete successfully against our current and future competitors, our business, financial condition and operating results could be harmed.

Our current and prospective customers tend to evaluate our capabilities against the merits of their internal manufacturing as well as the capabilities of other third-party manufacturers. We believe the internal manufacturing capabilities of current and prospective customers are our primary competition. This competition is particularly strong when our customers have excess manufacturing capacity, as was the case when the markets that we serve experienced a significant downturn in 2008 and 2009 that resulted in underutilized capacity. Should our existing and potential customers have excess manufacturing capacity at their facilities, it could adversely affect our business. In addition, as a result of the 2011 flooding in Thailand, some of our customers began manufacturing products internally or using other third-party manufacturers that were not affected by the flooding. If our customers choose to manufacture products internally rather than to outsource production to us, or choose to outsource to a third-party manufacturer, our business, financial condition and operating results could be harmed.

Competitors in the market for optical manufacturing services include Benchmark Electronics, Inc., Celestica Inc.,Sanmina-SCI Corporation, Jabil Circuit, Inc., and Venture Corporation Limited. Our customized optics and glass operations face competition from companies such as Browave Corporation, Fujian Castech Crystals, Inc., Photop Technologies, Inc., and Research Electro-Optic, Inc. Our UK competitors for printed circuit board assemblies include STI Limited and Axiom Manufacturing Services Limited. Other existing contract manufacturing companies, original design manufacturers or outsourced semiconductor assembly and test companies could also enter our target markets. In addition, we may face more competitors as we attempt to penetrate new markets.

Many of our customers and potential competitors have longer operating histories, greater name recognition, larger customer bases and significantly greater resources than we have. These advantages may allow them to devote greater resources than we can to the development and promotion of service offerings that are similar or superior to our service offerings. These competitors may also engage in more extensive research and development, undertake morefar-reaching marketing campaigns, adopt more aggressive pricing policies or offer services that achieve greater market acceptance than ours. These competitors may also compete with us by making more attractive offers to our existing and potential employees, suppliers, and strategic partners. Further, consolidation in the optics industry could lead to larger and more geographically diverse competitors. New and increased competition could result in price reductions for our services, reduced gross profit margins or loss of market share. We may not be able to compete successfully against our current and future competitors, and the competitive pressures we face may harm our business, financial condition and operating results.

Cancellations, delays or reductions of customer orders and the relatively short-term nature of the commitments of our customers could harm our business, financial condition and operating results.

We do not typically obtain firm purchase orders or commitments from our customers that extend beyond 13 weeks. While we work closely with our customers to develop forecasts for periods of up to one year, these forecasts are not binding and may be unreliable. Customers may cancel their orders, change production quantities from forecasted volumes or delay production for a number of reasons beyond our control. Any material delay, cancellation or reduction of orders could cause our revenues to decline significantly and could cause us to hold excess materials. Many of our costs and operating expenses are fixed. As a result, a reduction in customer demand could decrease our gross profit and harm our business, financial condition and operating results.

In addition, we make significant decisions, including production schedules, material procurement commitments, personnel needs and other resource requirements, based on our estimate of our customers’ requirements. The short-term nature of our customers’ commitments and the possibility of rapid changes in demand for their products reduce our ability to accurately estimate the future requirements of our customers. Inability to forecast the level of customer orders with certainty makes it difficult to allocate resources to specific customers, order appropriate levels of materials and maximize the use of our manufacturing capacity. This could also lead to an inability to meet a spike in production demand, all of which could harm our business, financial condition and operating results.

Our exposure to financially troubled customers or suppliers could harm our business, financial condition and operating results.

We provide manufacturing services to companies, and rely on suppliers, that have in the past and may in the future experience financial difficulty, particularly in light of uncertainty in the credit markets and the overall economy that affected access to capital and liquidity. As a result, we devote significant resources to monitor receivables and inventory balances with certain of our customers. If our customers experience financial difficulty, we could have difficulty recovering amounts owed to us from these customers, or demand for our services from these customers could decline. For example, in July 2014, one of our customers filed for bankruptcy protection under the Local Trade Court in France; although the bankruptcy of this customer did not have a significant effect on our consolidated financial statements, the same may not be the case if a significant customer were to file for bankruptcy protection in the future. As another example, another customer temporarily ceased operations in December 2018 and is currently on a payment plan with us. We have not recorded any impairment charges related to this customer but are continuing to monitor its situation. If our suppliers experience financial difficulty, we could have trouble sourcing materials necessary to fulfill production requirements and meet scheduled shipments. Any such financial difficulty could adversely affect our operating results and financial condition by resulting in a reduction in our revenues, a charge for inventory write-offs, a provision for doubtful accounts, and an increase inlarger working capital requirements due to increases inincreased days in inventory and in days in accounts receivable. For example, in July 2014, one of our customers filed for bankruptcy protection under the Local Trade Court in France; however, the potential losses from this particular customer did not have a significant effect on our consolidated financial statements.

Natural disasters (like the 2011 flooding in Thailand), epidemics, acts of terrorism and other political and economic developments could harm our business, financial condition, and operating results.

Natural disasters, such as the 2011 flooding in Thailand, where most of our manufacturing operations are located, could severely disrupt our manufacturing operations and increase our supply chain costs. These events, over which we have little or no control, could cause a decrease in demand for our services, make it difficult or impossible for us to manufacture and deliver products and for our suppliers to deliver components allowing us to manufacture those products, require large expenditures to repair or replace our facilities, or create delays and inefficiencies in our supply chain. For example, the 2011 flooding in Thailand forced us to temporarily shut down all of our manufacturing facilities in Thailand and cease production permanently at our Chokchai facility in Thailand, which adversely affected our ability to meet our customers’ demands during fiscal year 2012. In some countries in which we operate, including the PRC and Thailand, potential outbreaks of infectious diseases such as the H1N1 influenza virus, severe acute respiratory syndrome (“SARS”) or bird flu could disrupt our manufacturing operations, reduce demand for our customers’ products and increase our supply chain costs. In addition, increased international political instability, evidenced by the threat or occurrence of terrorist attacks,

significant exposure to changes in the exchange rate between the Thai baht and the U.S. dollar, and our operating results are adversely impacted when the U.S. dollar depreciates relative to the Thai baht and other currencies. We have experienced such depreciation in the U.S. dollar as compared with the Thai baht, and our results have been adversely impacted by this fluctuation in exchange rates. As of June 29, 2018,28, 2019, the U.S. dollar had depreciated approximately 2%9.5% against the Thai baht since June 30, 2017. Further, while we attempt to hedge against certain exchange rate risks, we typically enter into hedging contracts with maturities of up to 12 months, leaving us exposed to longer term changes in exchange rates.

Also, we have significant exposure to changes in the exchange rate between the Chinese Renminbi (“RMB”) and pound sterling (“GBP”) and the U.S. dollar. The expenses of our subsidiaries located in the PRC and the United Kingdom are denominated in RMB and GBP, respectively. Currently, RMB are convertible in connection with trade- and service-related foreign exchange transactions, foreign debt service, and payment of dividends. The PRC government may at its discretion restrict access in the future to foreign currencies for current account transactions. If this occurs, our PRC subsidiary may not be able to pay us dividends in U.S. dollars without prior approval from the PRC State Administration of Foreign Exchange. In addition, conversion of RMB for most capital account items, including direct investments, is still subject to government approval in the PRC. This restriction may limit our ability to invest the earnings of our PRC subsidiary. As of June 29, 2018,28, 2019, the U.S. dollar had depreciated approximately 10%0.6% against the RMB since June 30, 2017. There remains significant international pressure on the PRC government to adopt a substantially more liberalized currency policy. GBP are convertible in

customers to manufacture products for any of our other customers. Additionally, we could experience reduced or delayed product shipments or incur additional inventory write-downs and cancellation charges or penalties, which would increase costs and could harm our business, financial condition and operating results. While our agreements with customers are structured to mitigate our risks related to excess or obsolete inventory, enforcement of these provisions may result in material expense, and delay in payment for inventory. If any of our significant customers becomes unable or unwilling to purchase inventory or does not agree to such contractual provisions in the future, our business, financial condition and operating results may be harmed.

We conduct operations in a number of countries, which creates logistical and communications challenges for us and exposes us to other risks and challenges that could harm our business, financial condition and operating results.

The vast majority of our operations, including manufacturing and customer support, are located primarily in the Asia-Pacific region. The distances between Thailand, the PRC and our customers and suppliers globally, create a number of logistical and communications challenges for us, including managing operations across multiple time zones, directing the manufacture and delivery of products across significant distances, coordinating the procurement of raw materials and their delivery to multiple locations and coordinating the activities and decisions of our management team, the members of which are based in different countries.

we manufacture and (2) our customers’ ability to export or sell products that we manufacture for them. The majorityexport of our assetscertain technologies from the United States, the United Kingdom and manufacturing operations are located in Thailand. Therefore, political, social, businessother nations to the PRC is barred by applicable export controls, and economic conditions insimilar prohibitions could be extended to Thailand, have a significant effect on our business. In March 2018, Thailand was assessed as a medium-high overall risk by AON Political Risk, a risk management, insurance and consulting firm. Any changes to tax regimes, laws, exchange controls or political action in Thailand may harm our business, financial condition and operating results.

Thailand has a history of political unrest that includes the involvement of the military as an active participant in the ruling government. In recent years, political unrest in the country has sparked political demonstrations and, in some instances, violence. In May 2014, the Thai military took over the government in a coup, and it continues to rule the country today. It is unknown how long it may take for the current political situation to be resolved and for democracy to be restored, or what effects the current political situation may have on Thailand and the surrounding region. In October 2016, Thailand’s King Bhumibol Adulyadej died at the age of 88, and was recently succeeded by his son King Maha Vajiralongkorn. While this was a peaceful succession, any future succession crisis or political instability in the Kingdom of Thailand could prevent shipments from entering or leaving the country, disruptthereby limiting our ability to manufacture productscertain products. Any change in Thailand, and force usexport or import regulations or related legislation, shift in approach to transferthe enforcement of existing regulations, or change in the countries, persons or technologies targeted by such regulations, could limit our operationsability to more stable, and potentially more costly, regions.

Further, the Thai government may raise the minimum wage standards for labor and could repeal certain promotional certificates that we have receivedoffer our manufacturing services to existing or tax holidays for certain export and value added taxes that we enjoy, either preventing us from engaging in our current or anticipated activities or subjecting us to higher tax rates. A new regime could nationalize our business or otherwise seize our assets and any other future political instabilitypotential customers, which could harm our business, financial condition and operating results.

For example, in May 2019, the U.S. Commerce Department’s Bureau of Industry and Security (BIS) added Huawei and certain affiliates to the BIS Entity List. This action denied Huawei the ability to purchase products, software and technology that are subject to U.S. Export Administration Regulations (EAR). Although we do not sell directly to Huawei, some of our customers do sell to Huawei directly. To ensure compliance, some of our customers immediately suspended shipments to Huawei in order to begin assessments of the products they sold to Huawei (and its affiliates), to determine whether these products were subject to the restrictions resulting from the ban. This had an immediate impact on our customer orders in the fourth quarter of fiscal 2019, which affected our revenue for the quarter. We expect this ban to continue to invest inadversely affect orders from our manufacturing operations incustomers for the PRC, which will continue to expose usforeseeable future.

We are subject to risks inherentrelated to the ongoing U.S.-China trade dispute, including increased tariffs on materials that we use in doing business in the PRC, any ofmanufacturing, which risks could harmadversely affect our business, financial condition and operating results.result.

We anticipateThe U.S. Presidential Administration recently imposed tariffs on a wide-range of products and goods manufactured in China that are directly or indirectly imported into the Unites States, and it has announced plans to impose additional tariffs on products and goods manufactured in China. In response, various countries and economic regions have announced plans or intentions to impose retaliatory tariffs on a wide-range of products they import from the United States. These newly imposed, announced and threatened U.S. tariffs and retaliatory tariffs could have the effect of increasing the cost of materials we will continueuse to investmanufacture certain products, which could result in lower margins. The tariffs could also result in disruptions to our supply chain, as suppliers struggle to fill orders from companies trying to purchase goods in bulk ahead of announced tariffs. The institution of trade tariffs both globally and between the U.S. and China specifically could also cause a decrease in the sales of our customers’ products to end users located in China, which could directly impact our revenues in the form of reduced orders. If existing tariffs are raised further or if new tariffs are imposed on additional categories of components used in our customized optics manufacturing facilities located in Fuzhou, China. Because these operationsactivities, and if we are located in the PRC, they are subjectunable to greater political, legal and economic risks than the geographies in which the facilities of many of our competitors and customers are located. In particular, the political and economic climate in the PRC (both at national and regional levels) is fluid and unpredictable. In March 2018, AON Political Risk assessed the PRC as a medium overall risk. A large part of the PRC’s economy is still being operated under varying degrees of control by the PRC government. By imposing industrial policies and other economic measures, such as control of foreign exchange, taxation, import and export tariffs, environmental regulations, land use rights, intellectual property and restrictions on foreign participation in the domestic market of various industries, the PRC government exerts considerable direct and indirect influencepass on the developmentcosts of the PRC economy. Many of the economic reforms carried out by the PRC government are unprecedented or experimental and are expectedsuch tariffs to change further. Any changes to the political, legal or economic climate in the PRC could harm our business, financial condition andcustomers, our operating results.

Our PRC subsidiary is a “wholly foreign-owned enterprise” and is therefore subject to laws and regulations applicable to foreign investment in the PRC, in general, and laws and regulations applicable to wholly

If we fail to adequately expand our manufacturing capacity, we will not be able to grow our business, which would harm our business, financial condition and operating results. Conversely, if we expand too much or too rapidly, we may experience excess capacity, which would harm our business, financial condition and operating results.

We may not be able to pursue many large customer orders or sustain our historical growth rates if we do not have sufficient manufacturing capacity to enable us to commit to provide customers with specified quantities of products. If our customers do not believe that we have sufficient manufacturing capacity, they may: (1) outsource all of their production to another source that they believe can fulfill all of their production requirements; (2) look to a second source for the manufacture of additional quantities of the products that we currently manufacture for them; (3) manufacture the products themselves; or (4) otherwise decide against using our services for their new products.

MostWe most recently we expanded our manufacturing capacity by building a new facility in Chonburi, Thailand, which was completed in March 2017. We may continue to devote significant resources to the expansion of our manufacturing capacity, and any such expansion will be expensive, will require management’s time and may disrupt our operations. In the event we are unsuccessful in our attempts to expand our manufacturing capacity, our business, financial condition and operating results could be harmed.

However, if we expand our manufacturing capacity and are unable to promptly utilize the additional space due to reduced demand for our services, an inability to win new projects, new customers or penetrate new markets, or if the optics industry does not grow as we expect, we may experience periods of excess capacity, which could harm our business, financial condition and operating results.

Political unrest and demonstrations, as well as changes in the political, social, business or economic conditions in Thailand, could harm our business, financial condition and operating results.

The majority of our assets and manufacturing operations are located in Thailand. Therefore, political, social, business and economic conditions in Thailand have a significant effect on our business. In March 2019, Thailand was assessed as a medium-high overall risk by AON Political Risk, a risk management, insurance and consulting firm. Any changes to tax regimes, laws, exchange controls or political action in Thailand may harm our business, financial condition and operating results.

Thailand has a history of political unrest that includes the involvement of the military as an active participant in the ruling government. In recent years, political unrest in the country has sparked political demonstrations and, in some instances, violence. In March 2019, Thailand held its first general election since the Thai military took over the government in a coup in May 2014. In June 2019, General PrayutChan-o-cha was elected as Prime Minister, and in July 2019, the new Prime Minister’s nominees for cabinet ministers were appointed. Any future political instability in the Kingdom of Thailand could prevent shipments from entering or leaving the country, disrupt our ability to manufacture products in Thailand, and force us to transfer our operations to more stable, and potentially more costly, regions.

Further, the Thai government may raise the minimum wage standards for labor and could repeal certain promotional certificates that we have received or tax holidays for certain export and value added taxes that we enjoy, either preventing us from engaging in our current or anticipated activities or subjecting us to higher tax rates. A new regime could nationalize our business or otherwise seize our assets and any other future political instability could harm our business, financial condition and operating results.

We expect to continue to invest in our manufacturing operations in the PRC, which will continue to expose us to risks inherent in doing business in the PRC, any of which risks could harm our business, financial condition and operating results.

We anticipate that we will continue to invest in our customized optics manufacturing facilities located in Fuzhou, China. Because these operations are located in the PRC, they are subject to greater political, legal and economic risks than the geographies in which the facilities of many of our competitors and customers are located. In particular, the political and economic climate in the PRC (both at national and regional levels) is fluid and unpredictable. In March 2019, AON Political Risk assessed the PRC as a medium overall risk. A large part of the PRC’s economy is still being operated under varying degrees of control by the PRC government. By imposing industrial policies and other economic measures, such as control of foreign exchange, taxation, import and export tariffs, environmental regulations, land use rights, intellectual property and restrictions on foreign participation in the domestic market of various industries, the PRC government exerts considerable direct and indirect influence on the development of the PRC economy. Many of the economic reforms carried out by the PRC government are unprecedented or experimental and are expected to change further. Any changes to the political, legal or economic climate in the PRC could harm our business, financial condition and operating results.

Our PRC subsidiary is a “wholly foreign-owned enterprise” and is therefore subject to laws and regulations applicable to foreign investment in the PRC, in general, and laws and regulations applicable to wholly foreign-owned enterprises, in particular. The PRC has made significant progress in the promulgation of laws and regulations pertaining to economic matters such as corporate organization and governance, foreign investment, commerce, taxation and trade. However, the promulgation of new laws, changes in existing laws and abrogation of local regulations by national laws may have a negative impact on our business and prospects. In addition, these laws and regulations are relatively new, and published cases are limited in volume andnon-binding. Therefore, the interpretation and enforcement of these laws and regulations involve significant uncertainties. Laws may be changed with little or no prior notice, for political or other reasons. These uncertainties could limit the legal protections available to foreign investors. Furthermore, any litigation in the PRC may be protracted and result in substantial costs and diversion of resources and management’s attention.

Natural disasters (like the 2011 flooding in Thailand), epidemics, acts of terrorism and other political and economic developments could harm our business, financial condition, and operating results.

Natural disasters, such as the 2011 flooding in Thailand, where most of our manufacturing operations are located, could severely disrupt our manufacturing operations and increase our supply chain costs. These events, over which we have little or no control, could cause a decrease in demand for our services, make it difficult or impossible for us to manufacture and deliver products and for our suppliers to deliver components allowing us to manufacture those products, require large expenditures to repair or replace our facilities, or create delays and inefficiencies in our supply chain. For example, the 2011 flooding in Thailand forced us to temporarily shut down all of our manufacturing facilities in Thailand and cease production permanently at our Chokchai facility in Thailand, which adversely affected our ability to meet our customers’ demands during fiscal year 2012. In some countries in which we operate, including the PRC and Thailand, potential outbreaks of infectious diseases such as the H1N1 influenza virus, severe acute respiratory syndrome (“SARS”) or bird flu could disrupt our manufacturing operations, reduce demand for our customers’ products and increase our supply chain costs. In addition, increased international political instability, evidenced by the threat or occurrence of terrorist attacks, enhanced national security measures, conflicts in the Middle East and Asia, strained international relations arising from these conflicts and the related decline in consumer confidence and economic weakness, may hinder our ability to do business. Any escalation in these events or similar future events may disrupt our operations and the operations of our customers and suppliers, and may affect the availability of materials needed for our manufacturing services. Such events may also disrupt the transportation of materials to our manufacturing facilities and finished products to our customers. These events have had, and may continue to have, an adverse impact on the U.S. and world economy in general, and customer confidence and spending in particular, which in turn could adversely affect our total revenues and operating results. The impact of these events on the volatility

of the U.S. and world financial markets also could increase the volatility of the market price of our ordinary shares and may limit the capital resources available to us, our customers and our suppliers.

We are not fully insured against all potential losses. Natural disasters or other catastrophes could adversely affect our business, financial condition and operating results.

Our current property and casualty insurance covers loss or damage to our property and third-party property over which we have custody and control, as well as losses associated with business interruption, subject to specified exclusions and limitations such as coinsurance, facilities locationsub-limits and other policy limitations and covenants. Even with insurance coverage, natural disasters or other catastrophic events, including acts of war, could cause us to suffer substantial losses in our operational capacity and could also lead to a loss of opportunity and to a potential adverse impact on our relationships with our existing customers resulting from our inability to produce products for them, for which we might not be compensated by existing insurance. This in turn could have a material adverse effect on our business, financial condition and operating results.

Unfavorable worldwide economic conditions may negatively affect our business, operating results and financial condition.

Volatility and disruption in the capital and credit markets, depressed consumer confidence, and negative global economic conditions have affected levels of business and consumer spending. Concerns about the potential default of various national bonds and debt backed by individual countries as well as the politics impacting these, could negatively impact the U.S. and global economies and adversely affect our financial results. In particular, Brexit and economic uncertainty in Europe has led to reduced demand in some of our customers’ optical communications product portfolios. Brexit could also lead to economic and legal uncertainty, including significant volatility in global stock markets and currency exchange rates, and increasingly divergent laws and regulations as the United Kingdom determines which European Union laws to replace or replicate. Any of these effects of Brexit, among others, could adversely affect our financial results.

Uncertainty about worldwide economic conditions poses a risk as businesses may further reduce or postpone spending in response to reduced budgets, tight credit, negative financial news and declines in income or asset values, which could adversely affect our business, financial condition and operating results and increase the volatility of our share price. In addition, our ability to access capital markets may be restricted, which could have an impact on our ability to react to changing economic and business conditions and could also adversely affect our business, financial condition and operating results.

We may experience manufacturing yields that are lower than expected, potentially resulting in increased costs, which could harm our business, operating results and customer relations.

Manufacturing yields depend on a number of factors, including the following:

Lower volume production due to continually changing designs generally results in lower yields. Manufacturing yields and margins can also be lower if we receive or inadvertently use defective or contaminated materials from our suppliers. In addition, our customer contracts typically provide that we will supply products at a fixed price each quarter, which assumes specific production yields and quality metrics. If we do not meet the

yield assumptions and quality metrics used in calculating the price of a product, we may not be able to recover the costs associated with our failure to do so. Consequently, our operating results and profitability may be harmed.

If the products that we manufacture contain defects, we could incur significant correction costs, demand for our services may decline and we may be exposed to product liability and product warranty claims, which could harm our business, financial condition, operating results and customer relations.

We manufacture products to our customers’ specifications, and our manufacturing processes and facilities must comply with applicable statutory and regulatory requirements. In addition, our customers’ products and the manufacturing processes that we use to produce them are often complex. As a result, products that we manufacture may at times contain manufacturing or design defects, and our manufacturing processes may be subject to errors or fail to be in compliance with applicable statutory or regulatory requirements. Additionally,

If we are unable to meet regulatory quality standards applicable to our manufacturing and quality processes for the products we manufacture, our business, financial condition or operating results could be harmed.

As a manufacturer of products for the optics industry, we are required to meet certain certification standards, including the following: ISO9001 for Manufacturing Quality Management Systems; ISO14001 for Environmental Management Systems; TL9000 for Telecommunications Industry Quality Certification; IATF16949 for Automotive Industry Quality Certification; ISO13485 for Medical Devices Industry Quality Certification; AS9100 for Aerospace Industry Quality Certification; NADCAP (National Aerospace and Defense Contractors Accreditation Program) for Quality Assurance throughout the Aerospace and Defense Industries; and OHSAS18001 for Occupational Health and Safety Management Systems. We also maintain compliance with various additional standards imposed by the U.S. Food and Drug Administration, or FDA, with respect to the manufacture of medical devices.

limited number of suppliers offering “conflict free” metals that can be used in the products we manufacture for our customers.

Although we do not anticipate any material adverse effects based on the nature of our operations and these laws and regulations, we will need to ensure that we and, in some cases, our suppliers comply with applicable laws and regulations. If we fail to timely comply with such laws and regulations, our customers may cease doing business with us, which would have a material adverse effect on our business, financial condition and operating results. In addition, if we were found to be in violation of these laws, we could be subject to governmental fines, liability to our customers and damage to our reputation, which would also have a material adverse effect on our business, financial condition and operating results.

intercompany agreements in place that provide for our California and Singapore subsidiaries to provide administrative services for the Cayman Islands Parent, and the Cayman Islands Parent has entered into manufacturing agreements with our Thai subsidiary. In general, related party transactions and, in particular, related party financing transactions, are subject to close review by tax authorities. Moreover, several jurisdictions in which we operate have tax laws with detailed transfer pricing rules that require all transactions withnon-resident related parties to be priced using arm’s length pricing principles and require the existence of contemporaneous documentation to support such pricing. Tax authorities in various jurisdictions could challenge the validity of our related party transfer pricing policies. Such a challenge generally involves a complex area of

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.

Any failure to protect our customers’ intellectual property that we use in the products we manufacture for them could harm our customer relationships and subject us to liability.

We focus on manufacturing complex optical products for our customers. These products often contain our customers’ intellectual property, including trade secrets andknow-how. Our success depends, in part, on our ability to protect our customers’ intellectual property. We may maintain separate and secure areas for customer proprietary manufacturing processes and materials and dedicate floor space, equipment, engineers and supply chain management to protect our customers’ proprietary drawings, materials and products. The steps we take to protect our customers’ intellectual property may not adequately prevent its disclosure or misappropriation. If we fail to protect our customers’ intellectual property, our customer relationships could be harmed and we may experience difficulty in establishing new customer relationships. In addition, our customers might pursue legal claims against us for any failure to protect their intellectual property, possibly resulting in harm to our reputation and our business, financial condition and operating results.

We have incurred and will continue to incur significant increased costs as a result of operating as a public company, and our management will be required to continue to devote substantial time to various compliance initiatives.

The Sarbanes-Oxley Act of 2002, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, as well as other rules implemented by the SEC and the New York Stock Exchange (“NYSE”), impose various requirements on public companies, including requiring changes in corporate governance practices. These and proposed corporate governance laws and regulations under consideration may further increase our compliance costs. If compliance with these various legal and regulatory requirements diverts our management’s attention from other business concerns, it could have a material adverse effect on our business, financial condition and operating results. The Sarbanes-Oxley Act requires, among other things, that we assess the effectiveness of our internal control over financial reporting annually and disclosure controls and procedures quarterly. While we are able to assert in this Annual Report on Form10-K that our internal control over financial reporting was effective as of June 29 2018,28, 2019, we cannot predict the outcome of our testing in future periods. If we are unable to assert in any future reporting periods that our internal control over financial reporting is effective (or if our independent registered public accounting firm is unable to express an opinion on the effectiveness of

liabilities and related reserves, revenues, expenses and income. Estimates, judgments and assumptions are inherently subject to change in the future, and any such changes could result in corresponding changes to the amounts of assets, liabilities, revenues, expenses and income. Any such changes could have a material adverse effect on our business, financial condition and operating results.

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

We are subject to governmental export and import controls in Thailand, the PRC, the United Kingdom and the United States that may limit our business opportunities. Various countries regulate the import of certain technologies and have enacted laws that could limit our ability to export or sell the products we manufacture. The export of certain technologies from the United States, the United Kingdom and other nations to the PRC is barred by applicable export controls, and similar prohibitions could be extended to Thailand, thereby limiting our ability to manufacture certain products. Any change in export or import regulations or related legislation, shift in approach to the enforcement of existing regulations, or change in the countries, persons or technologies targeted by such regulations, could limit our ability to offer our manufacturing services to existing or potential customers, which could harm our business, financial condition and operating results.

We are subject to the risk of increased tariffs on products and goods we purchase fromoff-shore sources (including Chinese sources) and directly or indirectly imported into the United States.

The U.S. Presidential Administration has recently implemented or announced plans to impose tariffs on a wide-range of products and goods manufactured in China that directly or indirectly are imported into the Unites States. In response, various countries and economic regions have announced plans or intentions to impose retaliatory tariffs on a wide-range of products they import from the United States. These newly imposed or threatened U.S. tariffs and retaliatory tariffs could have the effect of increasing the cost of materials we use to manufacture certain products, which could result in lower margins. The tariffs could also result in disruptions to our supply chain, as suppliers struggle to fill orders from companies trying to purchase goods in bulk ahead of announced tariffs. Although we currently believe that the incremental costs to us of these tariffs will be

Should financial market conditions worsen, investments in some financial instruments may pose risks arising from market liquidity and credit concerns. In addition, any deterioration of the capital markets could

If securities or industry analysts do not publish research or if they publish misleading or unfavorable research about our business, the market price and trading volume of our ordinary shares could decline.

Overview

We provide advanced optical packaging and precision optical, electro-mechanical and electronic manufacturing services to original equipment manufacturers (“OEMs”) of complex products such as optical communication components, modules andsub-systems, industrial lasers, automotive components, medical devices and sensors. We offer a broad range of advanced optical and electro-mechanical capabilities across the entire manufacturing process, including process design and engineering, supply chain management, manufacturing, complex printed circuit board assembly, advanced packaging, integration, final assembly and test.testing. Although we focus primarily onlow-volume production of a wide variety of high complexity products, which we refer to as“low-volume,high-mix,” we also have the capability to accommodate high-volume production. Based on our experience with and positive feedback we have received from our customers, we believe we are a global leader in providing these services to the optical communications, industrial lasers and automotive markets.

Our customer base includes companies in complex industries that require advanced precision manufacturing capabilities such as optical communications, industrial lasers, automotive and sensors. The products that we manufacture for our OEM customers include selective switching products; tunable transponders and transceivers; active optical cables; solid state, diode-pumped, gas and fiber lasers; and sensors. In many cases, we are the sole outsourced manufacturing partner used by our customers for the products that we produce for them.

We also design and fabricate application-specific crystals, lenses, prisms, mirrors, laser components, and substrates (collectively referred to as “customized optics”) and other custom and standard borosilicate, clear fused quartz, and synthetic fused silica glass products (collectively referred to as “customized glass”). We incorporate our customized optics and glass into many of the products we manufacture for our OEM customers, and we also sell customized optics and glass in the merchant market.

Fiscal years

We utilize a52-53 week fiscal year ending on the Friday in June closest to June 30. Fiscal year 2019 ended on June 28, 2019 and consisted of 52 weeks. Fiscal year 2018 ended on June 29, 2018 and consisted of 52 weeks. Fiscal year 2017 ended on June 30, 2017 and consisted of 53 weeks. Fiscal year 2016 ended on June 24, 2016 and consisted of 52 weeks.

Revenues

We believe our ability to expand our relationships with existing customers and attract new customers is due to a number of factors, including our broad range of complex engineering and manufacturing service offerings, flexiblelow-cost manufacturing platform, process optimization capabilities, advanced supply chain management, excellent customer service and experienced management team. Although we expect the prices we charge for our manufactured products to decrease over time (partly as a result of competitive market forces), we still believe we will be able to maintain favorable pricing for our services because of our ability to reduce cycle time, adjust our product mix by focusing on more complicated products, improve product quality and yields, and reduce material costs for the products we manufacture. We believe these capabilities will enable us to help our OEM customers reduce their manufacturing costs while maintaining or improving the design, quality, reliability and delivery times of their products.

Revenues, by percentage, from individual customers representing 10% or more of our total revenues in the respective periods were as follows:

Revenues by Geography

We generate revenues from three geographic regions: North America, Asia-Pacific, and Europe. Revenues are attributed to a particular geographic area based on thebill-to-location of our customers, notwithstanding that our customers may ultimately ship their products to end customers in a different geographic region. The substantial majority of our revenues are derived from our manufacturing facilities in Asia-Pacific.

The percentage of our revenues generated from abill-to-location outside of North America decreased from 53.4% in fiscal year 2017 to 53.1% in fiscal year 2018 to 52.3% in fiscal year 2019, which was partially due to a decrease in sales to our customers in Asia-Pacific by 0.2% and in Europe by 0.1%1.4%. Based on the short and medium term indications and forecasts from our customers, we expect that the portion of our future revenues attributable to customers in regions outside of North America will increase as compared with the portion of revenues attributable to such customers during fiscal year 2018.2019.

The following table presents percentages of total revenues by geographic regions:

supplier or in some cases, our own subsidiaries. Shortages from sole-source suppliers due to yield loss, quality concerns and capacity constraints, among other factors, may increase our expenses and negatively impact our gross profit margin or total revenues in a given quarter. Material costs include scrap material. Historically, scrap rate diminishes during a product’s life cycle due to process, fixturing and test improvement and optimization.

A second significant element of our cost of revenues is employee costs, including indirect employee costs related to design, configuration and optimization of manufacturing processes for our customers, quality testing, materials testing and other engineering services; and direct costs related to our manufacturing employees. Direct employee costs include employee salaries, insurance and benefits, merit-based bonuses, recruitment, training and retention. Historically, our employee costs have increased primarily due to increases in the number of employees necessary to support our growth and, to a lesser extent, costs to recruit, train and retain employees. Our cost of revenues is significantly impacted by salary levels in Thailand, the PRC and the United Kingdom, the fluctuation of the Thai baht, Chinese Renminbi (“RMB”) and Pound Sterling (“GBP”) against our functional currency, the U.S. dollar, and our ability to retain our employees. We expect our employee costs to increase as wages continue to increase in Thailand and the PRC. Wage increases may impact our ability to sustain our competitive advantage and may reduce our profit margin. We seek to mitigate these cost increases through improvements in employee productivity, employee retention and asset utilization.

Our infrastructure costs are comprised of depreciation, utilities, facilities management and overhead costs. Most of our facility leases are long-term agreements. Our depreciation costs include buildings and fixed assets, primarily at our Pinehurst and Chonburi campuses in Thailand, and capital equipment located at each of our manufacturing locations.

During fiscal yearyears 2019, 2018 fiscal yearand 2017, and fiscal year 2016, discretionary merit-based bonus awards were made to ournon-executive employees. Charges included in cost of revenues for bonus awards tonon-executive employees were $3.9 million, $3.5 million $3.2 million and $2.8$3.2 million for fiscal yearyears 2019, 2018 fiscal yearand 2017, and fiscal year 2016, respectively.

Share-based compensation expense included in cost of revenues was $5.7 million, $6.8 million $5.3 million and $2.0$5.3 million for fiscal yearyears 2019, 2018 fiscal yearand 2017, and fiscal year 2016, respectively.

Share-based compensation expense included in SG&A expenses was $11.5 million, $15.8 million $21.2 million and $7.9$21.2 million for fiscal yearyears 2019, 2018 fiscal yearand 2017, and fiscal year 2016, respectively.

Additional Financial Disclosures

Foreign Exchange

As a result of our international operations, we are exposed to foreign exchange risk arising from various currency exposures primarily with respect to the Thai baht. Although a majority of our total revenues is denominated in U.S. dollars, a substantial portion of our payroll plus certain other operating expenses are incurred and paid in Thai baht. The exchange rate between the Thai baht and the U.S. dollar has fluctuated substantially in recent years and may continue to fluctuate substantially in the future. We report our financial results in U.S. dollars and our results of operations have been and could in the future be negatively impacted if the Thai baht appreciates against the U.S. dollar. Smaller portions of our expenses are incurred in a variety of other currencies, including RMB, GBP, Canadian dollars, Euros, and Japanese yen, the appreciation of which may also negatively impact our financial results.

In order to manage the risks arising from fluctuations in foreign currency exchange rates, we use derivative instruments. We may enter into foreign currency exchange currency forward or put option contracts to manage foreign currency exposures associated with certain assets and liabilities and other forecasted foreign currency transactions and may designate these instruments as hedging instruments. The forward and put option contracts generally have maturities of up to 12 months. All foreign currency exchange contracts are recognized in the audited consolidated balance sheet as other current assets or other current liabilities and are measuredsheets at fair value. Gain or loss on our forward and put option contracts generally offset the assets, liabilities, and transactions economically hedged.
