Sustainable Supply Chain
Winbond anchored its sustainable supply chain program in "Practicing Responsible Procurement," and a "People-oriented", integrating ecosystem thinking into governance and day-to-day supply chain operations. Through the dual transformation pillars of digitalization and decarbonization, Winbond strengthened controls, data collection, and collaboration mechanisms to support measurable progress.
In a volatile operating environment, maintaining business continuity requires innovation and agile response. Winbond worked with suppliers through audits, training, and digital data systems to strengthen operational resilience and manage ESG risks across the supply base.
Winbond strengthened supplier engagement and expanded value-chain collaboration. In 2025, Winbond received an A rating in the CDP Supplier Engagement Assessment (SEA), achieving Leadership level recognition.
Through value-chain climate collaboration, Winbond supported partners’ low-carbon transition and co-developed a climate-resilient sustainable supply chain ecosystem.

Sustainable Raw Material Policy
Policy
The company aims to decrease sustainable impact (eg. the water usage, energy consumptions and waste generation) through preferentially adopts primary and secondary raw materials which affect environment and society with minimum influences during research and development, procurement, production, operation and services.
In order to innovate and develop more friendlier product, the company promotes the best practice of sustainable material usage through the cooperation with customer, suppliers and other business partners.
The Company ensures sustainability and verifiability by increasing the sourcing and use of sustainable raw materials, including recycled raw materials and third-party-verified inputs.
The company aims to protect habitat, decrease the pollutions and overexploitation on natural resources through avoiding operating in important biodiversity areas and using the materials from biodiversity areas during the process of product design and procurement.
Execution and Monitoring
The Company will regularly review and update the sustainable raw material policy to ensure it meets the latest environmental and social standards and continuously improves.
The Company will provide relevant training for employees to improve their understanding and practical ability of the sustainable raw material policy, to ensure that each employee can contribute to the realization of the company's sustainable development goals.
The Policy will be effective upon Chairman’s approval, and the same shall apply to any amendment thereto.

Sustainable Raw Material Management Process
Winbond’s sustainable raw material management process includes rigorous supplier selection and ongoing monitoring to ensure supply chain security and raw material quality. The process prioritizes supplier qualification reviews. During the selection stage, suppliers are evaluated based on quality system assessments (covering quality, delivery, service, technology, and supplier quality systems), the RBA Code of Conduct, and corporate sustainability development standards. Additionally, Winbond is a member of the Ministry of Economic Affairs' International Trade Administration's Internal Compliance Program (ICP), and during the traceability stage, it closely monitors the sanction lists updated by the United Nations Security Council and Taiwan's Ministry of Justice to effectively maintain supply chain security and safety. Suppliers that comply with the previously noted stages must subsequently provide third-party quality system certification, Process/Product Change Notice (PCN) management principles, and complete the hazardous substance management questionnaire. Outsourcing suppliers of safety products must also provide international safety certification and complete the "Safety Product outsourcing Safety Control Measures Audit Questionnaire.
A clause on ecological resource protection has been added to the "Winbond Supplier Code of Conduct," explicitly requiring suppliers to minimize their impact on society and the environment.
Winbond's Supply Chain Biodiversity Conservation
The environmental section of Winbond's Supplier Code of Conduct adds a new clause on the natural resources protection (including biodiversity, no deforestation, and land conservation) and explicitly requires suppliers to:
- Assess and manage the impacts of their production processes on the surrounding land, forests, water resources, and other ecological and environmental conditions. Ensure that their activities do not cause irreversible impacts on local communities, the environment, and natural ecosystems, and shall conduct continuous monitoring.
- Comply with biodiversity conservation laws and regulations, avoid operations that affect critical habitats, and participate in actions to conserve natural ecosystems.
- Commit to refraining from future operations in or near areas of significant biodiversity.
- If current operations are located near a biodiversity area, suppliers must commit to implementing mitigation measures, including avoidance, mitigation, restoration, and compensation.
- If current operations or the products and services provided involve deforestation, suppliers should commit to compensatory reforestation efforts and cease any future development activities.
Biodiversity impact analysis and supplier support
In 2025, Winbond evaluated biodiversity impacts across global supplier sites and will continue to provide necessary support to suppliers located in hotspots. For details, please refer to the Winbond TNFD Report.
Raw Material Program
In 2025, Winbond launched comprehensive traceability management for raw materials to minimize procurement impacts on primary environments. For key materials such as wafers, process chemicals, gases, and targets, Winbond established a sustainable raw materials evaluation system integrating five dimensions: quality, technology, commercial feasibility, environmental friendliness, and humanitarian considerations. Winbond continued to prioritize “wafer regeneration and circular utilization” as the primary initiative before 2027. Looking ahead, Winbond will introduce third-party verified sustainable raw materials while ensuring process quality, increase procurement ratios year by year, and strengthen professional training to empower front-line procurement personnel to embed sustainability capabilities into daily supply chain operations.
Sustainable raw materials training
To effectively enhance front-line procurement personnel’s understanding of sustainable raw materials and expand upstream traceability, Winbond introduced diversified sustainable raw materials training programs in 2025, totaling 470 person-hours.
In 2025, metal raw materials usage and recycled material usage ratios were as follows. Winbond will continue exploring circularity for metal raw materials and, in 2026, will further strengthen traceability for circular regeneration of metal raw materials and require raw materials suppliers, OSAT suppliers, and outsourced manufacturers to advance circular remanufacturing and product R&D, minimizing primary extraction and maximizing environmental friendliness.
