Of the aggregate square footage of our facilities, approximately 3.3 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 States, Israel and the Cayman Islands. See Part I, Item 2. Properties of this Annual Report on Form 10-K.

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.

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.

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:

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.

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 2025 and 2024, we had two customers that each contributed 10% or more of our revenues. During fiscal year 2025, NVIDIA Corporation and Cisco Systems, Inc. contributed 27.6% and 18.2%, respectively, of our revenues. During fiscal year 2024, NVIDIA Corporation and Cisco Systems, Inc. contributed 35.1% and 13.4%, 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.

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; and ISO/IEC 27001 for Information Security 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 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 and Venture Corporation Limited, 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 2025 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.

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

12

Table of Contents

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 27, 2025, 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, and there was no material impact to our tax provision for the year ended June 27, 2025. In future years, the Pillar Two framework for the global minimum tax may increase the level of income tax in both Thailand and other foreign jurisdictions where we operate or have a presence.

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.
