Materiality Analysis
Materiality analysis is the fundamental and most important process for both risk identification and the quality of sustainability reporting. In 2025, WNC conducted materiality analysis using a double materiality approach, in compliance with the disclosure principles in the latest GRI 3: Material Topics 2021 and under the European Sustainability Reporting Standards (ESRS) structure announced by the EU’s Corporate Sustainability Reporting Directive (CSRD) and European Financial Reporting Advisory Group (EFRAG). This evaluation assesses impact materiality: the external effects of WNC’s business operations on the economy, environment, and human rights; and financial materiality: how sustainability issues influence WNC’s financial position, business performance, and future development.
Regarding assessment methodologies, WNC complies with GRI standards and the AA1000 Stakeholder Engagement Standard (SES). In addition, it leverages the economic, environmental, and social impact evaluation models developed by the Value Balancing Alliance (VBA), the Harvard Business School’s Impact-Weighted Accounts project, and the London Benchmarking Group (LBG). These frameworks form the basis for analyzing the impact of sustainability issues on external society and natural ecosystems.

Materiality Analysis Process
Building on the dual-track assessment approach, WNC has established a four-step process for identifying materiality:

Step 1
Sustainability issues list and impact on external factors
- 22 sustainability topics
- 21 external factors that impact
- New topics: Ethical Management and Legal Compliance, Risk and Crisis Management, and Human Rights Management
Step 2
Stakeholder identification and materiality assessment
- 5 key stakeholder groups: Employees, shareholders/investors, suppliers/contractors, customers, and communities
- 3 key questionnaires on stakeholders’ level of concern, financial materiality, and impact materiality were sent out; 2,565 questionnaires were collected
Step 3
Double materiality analysis
- Develop a materiality matrix based on materiality analysis results of the 3 key questionnaires
- After the CSO reviews the 16 material topics, the topics are submitted to the Sustainable Development Committee and the Board for review and approval
Step 4
Management of material topics
- Compile information on impact of material topics on the value chain
- Formulate annual sustainability management goals

16 material topics
WNC selected the 16 material topics for its 2025 Sustainability Report based on the following two principles:
Principle 1: Results from the three key materiality questionnaires
- Stakeholders’ level of concern
- Financial Materiality
- Impact Materiality
Principle 2: Topics related to long-term sustainability goals set by WNC for the year 2030
Priority is given to sustainability topics that already have defined:
- strategic directions
- targets
- action plans
WNC identified 16 material topics, which were confirmed by senior management and subsequently submitted to the Board for approval and confirmation. These topics served as the foundation of the 2025 Sustainability Report and the advancement of sustainability initiatives.
The 16 material sustainability topics and the differences compared with the topics from the previous year are summarized in the table below:

- Ethical Management and Regulatory Compliance (Newly added)
- Operational and financial performance
