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 testing. We are capable of producing a wide variety of high complexity products in any mix and any volume. Based on our extensive experience and the positive feedback we have received from our customers, we believe we are a global leader in providing these services to the optical communications, automotive, and industrial lasers markets. Our customer base includes companies in complex industries that require advanced precision manufacturing capabilities such as optical communications, automotive, industrial lasers, medical, and sensors. In many cases, we are the sole outsourced manufacturing partner used by our customers for the products that we manufacture for them. The products that we manufacture for our OEM customers include: •optical communications devices, such as: •selective switching products, such as reconfigurable optical add-drop multiplexers (“ROADMs”), optical amplifiers, modulators and other optical components and modules that collectively enable network managers to route voice, video and data communications traffic through fiber optic cables at various wavelengths, speeds, and over various distances; •tunable lasers, transceivers, and transponders that eliminate, at a significant cost savings to the service provider, the need to stock individual fixed wavelength optical transceivers and transponders used in voice and data communications networks; and •active optical cables providing high-speed interconnect capabilities for data centers and computing clusters, as well as Infiniband, Ethernet, fiber channel and optical backplane connectivity; •solid state, diode-pumped, gas and fiber lasers (collectively referred to as “industrial lasers”) used across a broad array of industries, including semiconductor processing (wafer inspection, wafer dicing, wafer scribing), biotechnology and medical device (DNA sequencing, flow cytometry, hematology, antibody detection), metrology (instrumentation, calibration, inspection), and material processing (metal, polymer, textile drilling and cutting, annealing, marking, engraving, and welding); and •sensors, including differential pressure, micro-gyro, fuel and other sensors that are used in automobiles, and non-contact temperature measurement sensors for the medical industry. 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. Our revenues for the year ended June 26, 2026 (“fiscal year 2026”) increased by $1.22 billion, or 35.7%, from $3.42 billion for the year ended June 27, 2025 (“fiscal year 2025”) to $4.64 billion for fiscal year 2026. To better reflect our current business profile, beginning in the fourth quarter of fiscal year 2026, we updated our revenue category presentation from two categories (optical communications and non-optical communications) to three categories: (1) data center, (2) communications infrastructure, and (3) automotive, industrial and other markets. Prior periods have been recast to conform to the current presentation. See Note 3 of the Notes to Consolidated Financial Statements. Our percentage of revenues from data center products increased from 46.2% in fiscal year 2025 to 47.9% in fiscal year 2026, our percentage of revenues from communications infrastructure products increased from 30.7% in fiscal year 2025 to 33.3% in fiscal year 2026, and our percentage of revenues from automotive, industrial and other markets decreased from 23.1% in fiscal year 2025 to 18.8% in fiscal year 2026. 4 Table of Contents 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 of a wide variety of high complexity products in any mix and any volume. 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 and time-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 their end-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 are. Industry Background Optical Communications Many optical communications OEMs have reduced internal manufacturing capacity and transitioned to a low-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 accelerated time-to-market and time-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 rapid expansion of data center infrastructures. Carrier demand for optical communications network equipment has increased as a direct result of higher network utilization and increased demand for bandwidth capacity. The increase in network traffic volumes has been driven by increasing demand for voice, data and video services delivered over wired and wireless Internet protocol, or IP, networks. The bandwidth demands for data center access have been largely driven by social media applications and cloud services and continue to increase very rapidly. Automotive, Industrial Lasers, and Others The optical and electro-mechanical process technologies used in the optical communications market also have applications in other similarly complex end-markets that require advanced precision manufacturing capabilities, such as automotive, industrial lasers, medical, and sensors. These markets are substantially larger than the optical communications components and modules market. We expect growth in the automotive, industrial lasers, medical, and sensors markets will be driven by demand for: •industrial laser applications across a growing number of end-markets, particularly in semiconductor processing, biotechnology, metrology and materials processing; •precision, non-contact and low power requirement sensors, particularly in automotive, medical and industrial end-markets; and •lower cost products used on both enterprise and consumer levels. 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. 5 Table of Contents Our Competitive Strengths We believe we have succeeded in providing differentiated services to the optical communications, automotive, 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 commitment to total customer satisfaction.

We call this concept of segregating production by customer a “factory-within-a-factory.” We believe our approach maximizes intellectual property protection and provides greater opportunities to reduce cost and improve time to market for our customers’ products. •Vertical Integration Targeting Customized Optics and Glass: We believe our capabilities in the design and fabrication of high-value customized optics and glass are complementary to our manufacturing services. Specifically, these capabilities enable us to strategically align our business to our customers’ needs by streamlining our customers’ product development process and reducing the number of suppliers in our customers’ manufacturing supply chains. Also, we use these customized optics and glass products in certain of the components, modules and subsystems we manufacture, which enables us to shorten time to market and reduce the cost for our customers. We believe this level of vertical integration positions us to capitalize on further opportunities to cross-sell our design and fabrication capabilities. •Turn-Key Supply Chain Management: We have created a proprietary set of automated manufacturing resource planning tools designed specifically to address the unique inventory management demands of the production of a wide variety of high complexity products in any mix and any volume. Over the years, we have developed strong relationships with thousands of suppliers and implemented inventory management strategies with many of them, which enables us to obtain inventory on an as-needed basis and provide on-site stocking programs. We believe our deep expertise, relationships and capabilities in supply chain and materials management often allows us to further reduce costs and cycle times for our customers. 6 Table of Contents Our Growth Strategy The key elements of our growth strategy are to: •Strengthen Our Presence in the Optical Communications Market: We believe we are a leader in manufacturing products for the optical communications market. The optical communications market is growing rapidly, driven by the growth in demand for increased network bandwidth and penetration from core to metro networks and data center infrastructures. We believe this trend will continue to increase the demand for the products that we manufacture and the services we provide. We continue to invest resources in advanced manufacturing process and optical packaging technologies to support the manufacture of the next generation of complex optical products. •Leverage Our Technology and Manufacturing Capabilities to Continue to Diversify Our End-Markets: We intend to use our technological strengths in precision optical and electro-mechanical manufacturing, advanced packaging and process design engineering to continue our diversification into industrial lasers, medical, sensors, and other select markets that require similar capabilities. •Continue to Extend Our Customized Optics and Glass Vertical Integration: We will continue to extend our vertical integration into customized optics and glass in order to gain greater access to key components used in the complex products we manufacture as well as to continue our diversification into new markets. We believe our customized optics and glass capabilities are highly complementary to our optical and electro-mechanical manufacturing services, and we intend to continue to market these products to our existing manufacturing services customers. In addition, we intend to continue our focus on customized optics and glass through further investment into research and development, as well as through potential acquisitions in what remains a highly fragmented market. •Evaluate Potential Strategic Alternatives such as Acquisitions and Joint Ventures: We will continue to evaluate opportunities to further expand our manufacturing capabilities and diversify our end-markets through the evaluation of various acquisition and joint venture opportunities around the globe. •Broaden Our Client Base Geographically: Our manufacturing services are incorporated into products that are distributed in markets worldwide, but we intend to further build out our client base in strategic regions. We intend to continue our focus on expanding our client base in Europe, Asia-Pacific, the Middle East and the United States. We believe these regions have a large and robust optics market, as well as a need for advanced manufacturing services in other growth markets, and would benefit from our precision optical and electromechanical manufacturing services. •Establish New Product Introduction (“NPI”) Centers to Generate and Transfer New Business to Thailand: We established Fabrinet West, Inc. as an NPI center in the heart of Silicon Valley and Fabrinet Israel as an NPI center in Israel’s “Startup Village.” These NPI centers serve as business development arms with an emphasis on new business generation, helping our customers with design for manufacturability and then transferring those programs to Thailand for volume manufacturing. Equipped with state-of-the-art surface mount and advanced optical packaging technologies and infrastructure, and with close proximity to a large portion of our customer base, these centers help to accelerate customer NPI and provide seamless access and future transfer to the low-cost manufacturing base in Thailand. 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. 7 Table of Contents 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 development requirements of their new products and assist them to build prototypes, as well as source materials, optimize manufacturing processes and develop schedules to bring these products to volume production. We maintain a real-time roadmap for the packaging requirements of our customers and the industry in general. Our advanced packaging team develops and maintains generic recipes that are readily available to be tailored and refined for the specific new applications of our customers, which helps to further accelerate prototype development and product delivery time. Printed Circuit Board Assembly and Test Printed circuit board assembly involves attaching electronic components, such as integrated circuits, capacitors, receivers, transceivers and other components and modules to printed circuit boards. We employ a 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 perform in-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 a full suite of NPI services for quick-turn PCBA to box-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 with state-of-the-art production equipment that mirrors the equipment used in our low-cost manufacturing facilities, ensuring a fast, smooth transition to a low-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, eliminating non-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, expediting, warehousing and financing materials from thousands of suppliers. We have created a proprietary set of automated manufacturing resource planning tools to manage our inventory. We have also implemented inventory management strategies with certain suppliers that enable us to use inventory on an as-needed basis and provide on-site stocking programs. 8 Table of Contents Quality Control We believe the integration of our manufacturing and test controls, quality systems, and software platforms contribute significantly to our ability to deliver high-quality products on a consistent basis and reduce the risk that we will be required to repair or replace defective products. Our manufacturing execution system (“MES”) is 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 products follow the correct process steps and that 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: •Fiber Optic Ferrules and Alignment Sleeves; Fiber Optic Substrates; Precision Glass Tubing, Precision Capillaries and Rods: These single bore and multi-bore products, in various shapes and dimensions, are used principally in optical communications, medical and industrial applications. •Laser Optics: Includes crystals (such as YVO4, Nd: YVO4, Cr: YAG, and BBO), optics, high reflectivity mirrors, lenses, prisms and windows used in laser applications. •Medical Optics: Includes mirrors, lenses, filters, wave plates, windows, and prisms incorporated into various medical equipment products. •Storage Optics: Includes mirrors, polarizing beam splitters or PBS, and wave plates incorporated into optical storage products. •Surveying Optics: Includes penta prisms, corner cubes, and T-Windows incorporated into precision surveying products. •Telecom Optics: Includes lenses (such as spherical, a-spherical, C-lens, and cylindrical), wave plates, mirrors, prisms, filters and YVO4 crystals used for telecommunications applications. •Telecommunication Subassemblies: Includes fiber pigtails (both single and dual), assemblies and collimators used in many fiber optic components such as isolators, circulators, optical switches and three-port filters. 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 technologies to extend our product portfolio and continue to gain market share in the optics industry. Our internally developed and licensed technologies include the following: •Advanced Optical Packaging: We have extensive experience in developing manufacturing processes and performing value engineering to improve our customers’ product performance, quality, reliability and manufacturing yields. In many cases, we partner with our customers to develop custom manufacturing solutions for their optics products. •Reliability Testing: Our reliability laboratory enables us to test the degree to which our results and specifications conform to our customers’ requirements. Through the reliability laboratory, we are able to perform most of the tests required by industry standards, including damp heat, thermal aging, thermal shock, temperature cycling, shock and vibration, accelerated life testing and stress screening. The reliability laboratory is critical to verification of root cause failure analysis. •Optical and Mechanical Material and Process Analysis: Our in-house material and process laboratory analyzes materials to support incoming inspection, process development, process monitoring, failure analysis and verification of compliance with the applicable environmental standards. 9 Table of Contents •Precision Optical Fiber and Electro-Mechanical Assembly: We have extensive experience in precision optical and electro-mechanical assemblies in clean room environments, clean room control discipline, cleaning technologies and electro-static discharge (“ESD”) protection. •Fiber Metallization and Lensing: We use our fiber metallization and fiber lensing capabilities to assist our customers in packaging their products. Many optical component package designs require metallized fiber and some designs also require lensing at the tip of the fiber. We have in-house capabilities that enable us to produce these products at a low cost, with short lead times and high quality. •Fiber Handling and Fiber Alignment: The technique with which optical fiber is handled can have a significant impact on the functionality and reliability of optics products due to the risk of damage or flaws introduced to the fiber surface or micro-cracks to the core of the fiber, which may impact alignment or signal quality, among other things. We have implemented a number of processes, techniques, and best practices to avoid stressing or otherwise damaging fiber during stripping, cleaving and connectorization. Such techniques are also designed to achieve optimal alignment of fiber in the shortest period of time during these processes. •Optical Testing: We have the capability to perform parametric and functional tests for a wide variety of optical devices. In many cases, we are also able to help our customers develop their own proprietary software and test fixtures. •Crystal Growth and Processing: Our crystal growth technology produces non-linear optical crystals and crystals used in laser applications. Our processing capabilities include dicing, grinding, polishing and inspection with high dimension, tolerance and surface quality. •Precision Glass Drawing: We have developed the specialized capabilities necessary to draw precision structures within tight tolerances using borosilicate, clear fused quartz and synthetic fused silica glass. Using these processes, we produce customized rectangular and circular glass tubes and rods in various configurations and with multiple bores that are accurately drawn in precise locations within the tubing. These tubes can be sliced into thin wafers for use in various applications, such as ultra-filtration of bacteria, micro-organism counting, and identification of organisms and substances. These tubes can also be cut into larger lengths to produce ferrules and sleeves for use in fiber optic communications components. •Optical Coating: We provide a wide variety of coating from simple single layer anti-reflection coatings to complex multi-layer stacks. The types of coating we provide include anti-reflection, partial reflection and high reflection. We continuously invest in new and optimized processes to accommodate the next generation of optical devices, such as optical packaging, anti-reflective coating and complex printed circuit board technologies. We believe many of these manufacturing processes and technologies will be key to developing and commercializing the next generation of optical devices, which may include multi-function passive optics and photonic integrated circuits (which are devices that incorporate various optical components and modules into a packaged chip), receivers integrated with an optical amplifier, and active optical cabling. We also anticipate our customers will continue to desire our vertically integrated capabilities, designing customized optics and glass to be incorporated into optical components, modules and complete network or laser systems. Customers, Sales and Marketing The optical communications market we serve is highly concentrated. Therefore, we expect a significant percentage of our revenues will continue to come from a small number of customers. During fiscal years 2026 and 2025, we had four and two customers, respectively, that each contributed 10% or more of our revenues. During fiscal year 2026, Cisco Systems, Inc., NVIDIA Corporation, Nokia Corporation and Amazon.com, Inc. contributed 19.9%, 16.3%, 10.7% and 10.5%, respectively, of our revenues. During fiscal year 2025, NVIDIA Corporation and Cisco Systems, Inc. contributed 27.6% and 18.2%, respectively, of our revenues. 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, result in greater visibility into product life cycles and longer-term customer engagements. 10 Table of Contents Backlog We are substantially dependent on orders we receive and fill on a short-term basis. Although we often receive a 12-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 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 suppliers, which have prevented us from manufacturing products for our customers in a timely manner. Furthermore, in some cases, our efforts to identify and secure alternative supply chain sources has resulted in our customers or their end customers requiring requalification and validation of components, a process that can often be lengthy and has negatively impacted the timing of our revenue. 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 techniques and other tools to improve product and service quality. In addition, we generally offer a warranty ranging from one to five years on the products that we assemble. Generally, this warranty is limited to our workmanship and our liability is capped at the price of the product. Our quality management systems help to ensure that the products we provide to our customers meet or exceed industry standards. We maintain the following certifications: ISO 9001 for Manufacturing Quality Management Systems; ISO 14001 for Environmental Management Systems; TL 9000 for Telecommunications Industry Quality Certification; IATF 16949 for Automotive Industry Quality Certification; ISO 13485 for Medical Devices Industry Quality Certification; AS 9100 for Aerospace Industry Quality Certification; NADCAP (National Aerospace and Defense Contractors Accreditation Program) for Quality Assurance throughout the Aerospace and Defense Industries; ISO 45001 for Occupational Health and Safety Management Systems; ISO/IEC 17025 for Testing and Calibration Laboratories Certification; ISO 22301 for Business Continuity Management Systems; ISO/IEC 27001 for Information Security Management Systems; and ISO 50001 for Energy Management Systems. We also maintain compliance with various additional standards imposed by the U.S. Food and Drug Administration (“FDA”) with respect to the manufacture of medical devices. 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; Transported Asset Protection Association (“TAPA”) and Customs Trade Partnership Against Terrorism (“CTPAT”) for logistics security and management; and CSR-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. 11 Table of Contents Our overall competitive position depends upon a number of factors, including: •our manufacturing technologies and capacity; •the quality of our manufacturing processes and products; •our supply chain tools and data management systems; •our ability to safeguard and protect our customers’ intellectual property; •our engineering and prototyping capabilities; •our ability to strengthen and broaden our engineering services and know-how to participate in the growth of emerging technologies; •our ability to deliver on-time; •our ability to deliver continuous cost improvements; and •our responsiveness and flexibility. Competitors in the market for optical manufacturing services include Benchmark Electronics, Inc., Celestica Inc., InnoLight Technology (Suzhou) Ltd., Jabil Inc., Sanmina Corporation, Venture Corporation Limited and Eoptolink Technology Inc., Ltd., as well as the internal manufacturing capabilities of our customers. Our customized optics and glass operations face competition from companies such as CASTECH Inc., Excelitas Technologies Corp. and Photop Technologies, Inc. (a subsidiary of Coherent Corp.). Intellectual Property Our success depends, in part, on our ability to protect our customers’ intellectual property. We license various technologies from our customers on a non-exclusive, royalty-free, non-transferable basis for the sole purpose of allowing us to manufacture products for those customers in accordance with their specifications. We have no rights to disclose, use, sublicense or sell this licensed technology for any other purpose. The duration of these licenses is limited to the duration of the underlying supply or manufacturing agreement. To meet the demands of certain customers, we created a factory-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 developed in-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 and jointly-held PRC patents in various customized optic technologies with expiration dates between 2026 and 2040. 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. Government Regulations Environmental Compliance We are subject to a variety of international and U.S. laws and regulations 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. 12 Table of Contents As part of the International Organization for Standardization (“ISO”) 14001 environmental management systems framework, we have established and continue to enforce at our facilities a global environmental policy that includes evaluation and control, compliance obligations, commitment, training, communication, control of documented information, operational control, emergency preparedness and response, and management review. While environmental regulations have not thus far resulted in a material adverse effect on our operations, changes in regulations could necessitate additional capital expenditures, modification of our operations, or other compliance actions. Trade Regulations We and our suppliers and service providers could be affected by tariffs, embargoes, or other trade restrictions, as well as laws and regulations enacted in response to concerns regarding climate change, conflict minerals, responsible sourcing practices, public health crises, contagious disease outbreaks, or other matters, which could limit the supply of our materials and increase their cost. In addition, compliance with trade regulations may result in disruptions in logistics, which could delay our receipt of materials. We have experienced increased lead times and expedite fees for the supply of materials. The disruption of our supply of parts and materials, including where such disruption results in the extension of our lead times, could have a material adverse effect on our business, results of operations, or financial condition. Similarly, if our customers experience disruptions to their supplies or materials, or the extension of their lead times, they may reduce, cancel, or alter the timing of their purchases with us, which could have a material adverse effect on our business, financial condition and operating results. Tax Law Changes We are subject to income taxes in various jurisdictions. Our provision for income taxes and effective tax rate could be affected by numerous factors, including changes in applicable tax laws, interpretations of applicable tax laws, amount and composition of pre-tax income in jurisdictions with differing tax rates, and valuation of deferred tax assets. There have been a number of proposed changes in the tax laws that could increase our tax liability. As part of the Organization for Economic Cooperation and Development’s (“OECD”) Inclusive Framework on Base Erosion and Profit Shifting, over 140 countries have joined a two-pillar plan to reform international taxation rules. The first pillar is focused on the allocation of taxing rights between countries for in-scope multinational enterprises that sell goods and services into countries with little or no local physical presence and is intended to apply to multinational enterprises with global revenues above €20 billion. The second pillar is focused on developing a global minimum tax rate of at least 15% applicable to in-scope multinational enterprises and is intended to apply to multinational enterprises with annual consolidated group revenue in excess of €750 million. The OECD has issued Pillar Two model rules and continues to release guidance on these rules. As of June 26, 2026, these rules are either effective or have been adopted in draft form in various countries. We evaluated the applicable tax law changes resulting from Pillar Two implementation in the countries where we operate. Fabrinet is incorporated in a jurisdiction that has not adopted Pillar Two rules. Certain other jurisdictions in which we operate, including Thailand, have enacted legislation that may impose Undertaxed Profits Rule (UTPR) top-up tax with respect to low-taxed income of other constituent entities within our consolidated group. For the year ended June 26, 2026, we recognized $57.4 million of current income tax expense related to enacted Pillar Two UTPR legislation. The related liability is included within income tax payable in the consolidated balance sheets. We continue to evaluate enacted legislation, administrative guidance, and the application of transitional safe harbors in the jurisdictions in which we operate. Future changes in enacted tax laws and interpretations could materially affect our future effective tax rate and cash tax obligations. 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”), 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 member of the RBA. 13 Table of Contents Corporate Structure Fabrinet was incorporated under the laws of the Cayman Islands in August 1999 and commenced business operations in January 2000.
