Carefully vetting and partnering with like-minded suppliers
WT aims for long-term partnerships with General Affairs suppliers who share our core values. To this end, our management has established a “General Affairs Supplier Code of Conduct” for these suppliers. All General Affairs suppliers are required to sign the “Supplier Corporate Social Responsibility Commitment Letter” and complete an online “Supplier Self-Assessment Form.” Our procurement team evaluates the results of these self-assessments to identify potential risks in areas such as human rights, labor practices, consumer protection, ethical business conduct, environmental protection, and health and safety. We ensure that 100% of new GA suppliers are screened and selected based on environmental and social standards. In addition, we are committed to strengthening sustainability awareness among our GA suppliers to prevent major deficiencies or legal violations.
In 2024, WT Group has completed the signing of Corporate Social Responsibility Commitment Letters with existing General Affairs suppliers in Taiwan and China, achieving a 100% signing rate. Following the merger of Future Electronics into the group, the overall signing rate for target General Affairs suppliers across the entire group is 33.9%. Going forward, we will continue to integrate global General Affairs suppliers into a unified management system, strengthening our commitment and oversight on environmental, labor, and human rights issues to ensure the supply chain complies with the group’s responsible procurement policy.
In alignment with global environmental protection trends, WT revised the General Affairs Supplier Code of Conduct in 2024. New environmental requirements were added to ensure that suppliers comply with international, national, and local biodiversity regulations when conducting their operations and business activities. These requirements include avoiding deforestation and preventing harm to endangered or protected species, while also supporting forest and land conservation.
To maintain procurement quality, annual assessments are conducted for General Affairs suppliers with annual transaction amounts exceeding NT$1 million or with more than 12 transactions per year. The assessment scope includes supplier performance in delivery quality, delivery timeliness, service capability, ESG implementation, environmental protection, and occupational health and safety.
Assessment results are categorized into four levels: A, B, C, and D, we also track and facilitate improvements for suppliers rated C and D. In 2023, two suppliers received a C rating; one was replaced in 2024, while the other improved to a B rating after guidance and assistance, thus maintaining our partnership.
In 2024, the qualification rate (C-level and above) for suppliers in Taiwan and China reached 100%, with Class A suppliers accounting for 80.0%. Four suppliers received a C rating; while we provide guidance and support for improvement, we are also actively seeking alternative suppliers to enhance supply chain resilience and maintain supply levels and quality standards. We plan to integrate these assessment guidelines into our overseas operational sites in the future.
Due to the expanded scope of operations in 2024, the assessment of General Affairs suppliers this year still focused on WT’s existing suppliers, with an assessment rate of 100%. After the inclusion of Future Electronics, the overall assessment rate for target General Affairs suppliers across the entire group is 33.9%. Going forward, we will gradually expand the scope of assessments as planned and continue to improve the assessment processes and indicators to strengthen the sustainable risk management of the global supply chain.

General affairs supplier meeting: Sharing experiences and fostering growth with partners 
To promote the exchange of sustainability knowledge and practices across our supply chain, WT held a General Affairs Supplier Meeting in Taiwan in 2024. The event focused on three core themes: occupational health and safety, greenhouse gas (GHG) emissions, and green procurement, aiming to promote sustainability values among general affairs suppliers. Key topics included the importance of occupational accident prevention, reinforced through real-world incident case studies and an overview of relevant occupational safety regulations; an introduction to Taiwan’s GHG-related regulations and practical procedures for GHG inventory; WT’s energy-saving and carbon reduction strategies, along with short-, medium-, and long-term targets; and the standards used to assess suppliers’ sustainability performance during the procurement process. Through this educational initiative, WT and our suppliers jointly enhanced the quality of green procurement and enabled suppliers to better align their practices with future sustainability goals. The supplier meeting will continue to be held annually, with plans to extend the initiative to other overseas sites, maximizing the impact of sustainable development across the supply chain through top-down collaboration.
 
Continuous monitoring of Environmental and Social management by major suppliers 
WT is committed to promoting sustainable development in the supply chain. We encourage our major suppliers to provide high-quality products and services while complying with national regulations and policies. They must ensure that their products and manufacturing processes adhere to environmental and social responsibility standards. Suppliers are required to prohibit the use of hazardous substances (such as those restricted by the EU RoHS directive), ensure that raw materials do not contain conflict minerals, and sign a Conflict-Free Minerals Declaration, In 2024, there were no incidents of non-compliance with health and safety regulations related to products and services.
Additionally, WT encourages suppliers to adopt ISO certifications to enhance quality management. Suppliers are also urged to implement occupational safety measures, labor rights protections, and environmental protection initiatives, working together to establish a responsible and sustainable supply chain.
WT considers suppliers as long-term partners and maintains close communication with them. Through continuous engagement, we promote the implementation of environmental sustainability, social responsibility, and ethical standards. We also emphasize compliance and corporate responsibility in operations, ensuring that suppliers commit to ethical business practices, human rights principles, and corporate ethics.

PFASPFAS (Per- and Polyfluoroalkyl Substances) Management
In 2023, the EU introduced a proposal to ban PFAS, a broad class of synthetic chemicals known for their persistence, long-range transport potential, and bioaccumulation risks. These substances pose significant environmental and health hazards, including water pollution.
In industries such as semiconductors, no viable alternatives currently exist, and immediate production cessation is not feasible. Therefore, a transition period of 13-15 years will be implemented upon enforcement of the regulations.
WT continues to investigate PFAS usage in supplier products and discloses this information to customers, aiming to mitigate environmental and health risks.
Carbon Footprint and Net-Zero Emission Goals
In response to global carbon reduction initiatives, WT is dedicated to carbon footprint assessments, aiming to reduce, capture, and reuse greenhouse gas emissions. The long-term goal is to achieve Net Zero Emissions by 2050, transforming carbon reduction efforts into competitive advantages and steadily implementing sustainability initiatives.

The customer requests products with conflict minerals traceability, 100% sourced from qualified smelters
Conflict Minerals Sourcing and Traceability Mechanisms 
Referencing international concerns about conflict minerals originating from regions with human rights issues, and in support of universal humanitarian values in supply chain practices, WT published its Conflict Minerals Policy on the company website in 2023. The policy mandates that all major suppliers comply with the U.S. Securities and Exchange Commission’s (SEC) conflict minerals regulation – Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (DFCMA). Vendors are required to fully disclose the sources of conflict minerals used in their manufacturing processes, including gold (Au), tantalum (Ta), tin (Sn), and tungsten (W) – collectively referred to as 3TG – and indicate whether these materials originate from high-risk mines in the Democratic Republic of the Congo (DRC) and neighboring countries.
To ensure conflict-free sourcing, WT regularly reviews major suppliers’ conflict minerals policies and traces the origins of materials in distributed products. The company actively monitors smelter assessment updates published by the Responsible Minerals Initiative (RMI), and requests vendors to submit the latest Conflict Minerals Reporting Template (CMRT), Extended Minerals Reporting Template (EMRT), or Additional Minerals Reporting Template (AMRT), in alignment with customer requirements.
