Process of Materiality Analysis

Each year, Wistron conducts its double materiality assessment in accordance with GRI 3: Material Topics 2021 under the GRI Universal Standards 2021, while also taking into consideration the concept of Double Materiality as set out in the European Sustainability Reporting Standards (ESRS). Drawing on the impact assessment methodologies for economic, environmental, and social dimensions developed by the Value Balancing Alliance (VBA), the Harvard Business School's Impact-Weighted Accounts research project, and the Business for Social Impact (B4SI) framework, Wistron integrates the Company's sustainability context to identify sustainability issues with material impact. Financial materiality covers sustainability issues where sustainability-related risks and opportunities have a significant impact on its operations and financial position. Based on these international frameworks, Wistron has established a four-step process grounded in double materiality: identifying sustainability issues; distributing and analyzing questionnaires (covering impact and financial materiality assessments); determining material issues; and confirming material issues. After review by senior executives and internal and external experts, the assessment process and results are signed off by the Board of Directors. Fifteen sustainability issues were confirmed as material for disclosure in the 2025 Sustainability Report. These are further integrated with the Company's Enterprise Risk Management (ERM) process to identify risk types, severity, and frequency, and to develop mitigation measures. The results of the materiality analysis were verified by a third-party to confirm the disclosure boundaries and scope of information. The materiality analysis process is listed below:

Materiality analysis

Considering both “dynamic materiality” and “double materiality” simultaneously, Wistron conducted its materiality analysis from 3 perspectives: internal/external stakeholder concerns, impact to the organization’s operation and sustainable development impact. Regarding sustainable development impact, Wistron integrated both monetary and non-monetary valuation methods for impact assessment. Wistron applies the monetary valuation methods for its periodic sustainability impact evaluations; non-monetary valuation methods are implemented in the annual materiality analysis.
 
Questionnaire 1: Internal and External Stakeholder Concerns
Questionnaire 2: Sustainability Impacts, Outward Impact
Questionnaire 3: Impact on Operations, Inward Impact
Questionnaire: Financial Impact of Sustainability Risks and Opportunities, Inward Impact

Internal and External Stakeholder Concerns

Wistron invited subsidiaries to participate in a questionnaire survey to collect the level of concern regarding various sustainability issues among internal and external stakeholders. A total of 1,491 valid responses were collected, including:
  • customers (35)
  • employees (977)
  • suppliers/contractors (395)
  • shareholders/investors (31)
  • government/industry associations (6)
  • non-profit organizations/communities (44)
  • media (3)

Sustainability Impacts, Outward Impact

Wistron uses Impact Valuation, applied from both monetary and non-monetary perspectives, to measure the positive and negative external sustainability impacts arising from upstream activities, Wistron's own operations, and downstream products and services. Drawing on methodologies from the Value Balancing Alliance (VBA), the Harvard Business School Impact-Weighted Accounts research project, and the London Benchmarking Group (LBG), and taking into account Wistron's strategies and operational practices, the Company defined 21 external sustainability impacts relevant to its business, covering economic, environmental, and human/human rights dimensions. Twenty-four managers and colleagues from the core internal ESG teams were invited to help assess likelihood, severity, and remediability, with 16 sustainability impacts ultimately identified as having significant relevance to Wistron.
 
  • Wistron Sustainability Impact Analysis – Non-monetary
  • Wistron Sustainability Impact Analysis – Monetary
Wistron aims to create long-term value for stakeholders by establishing an Impact Measurement and Valuation (IMV) framework grounded in a profit and loss. This framework incorporates the Triple Bottom Line (TBL) management approach, encompassing economic, environmental, and social dimensions, and adopts an outside-in perspective to systematically assess the positive and negative impacts of its value chain activities on human well-being, society, and the economy. Wistron adopts a biennial cycle for its in-depth impact identification process, undertaking a systematic inventory and comprehensive assessment of the environmental and social externalities generated at each stage of the value chain. Wistron also supplements this approach with an Annual Dynamic Review mechanism, through which it continuously monitors international trends, regulatory developments, operational changes, and key stakeholder concerns on an annual basis. Based on actual circumstances, the boundaries and scope of impact assessments are updated and adjusted as necessary to ensure the completeness and timeliness of disclosed information, while also optimizing the allocation of management resources. This approach is aligned with the principles set forth in international sustainability disclosure standards, including the GRI Standards and ESRS, which call for the ongoing review and timely updating of impact materiality assessments. In 2024, Wistron's value chain activities generated NT$1.18 trillion in positive impact on human well being, alongside NT$13.4 billion in negative impacts. These impacts primarily stemmed from the management of sustainability issues such as sustainable supply chain management, customer relations, green products, circular economy, climate strategy and energy management, talent cultivation & development, talent attraction and retention, and product R&D and innovation.

Impact on Operations, Inward Impact

Wistron integrates sustainability with financial impact, connecting overall corporate development with financial strategy, and assesses each sustainability issue's effect on operations from a financial materiality perspective. Twelve senior-level executives were invited to participate in the survey, assessing each
issue's impact on revenue, employee engagement, customer satisfaction, operational risk, and brand image.

Financial Impact of Sustainability Risks and Opportunities, Inward Impac

Wistron is committed to embedding sustainability into daily business operations, and assesses the financial impact of sustainability initiatives on the Company from an operational perspective. To this end, Wistron invited 21 managers and employees responsible for sustainability initiatives to participate in the assessment, identifying the sustainability risks and opportunities associated with each department's day-to-day operations and sustainability-related activities. Cases disclosed by international peers were also reviewed to build Wistron's list of sustainability risks and opportunities. During the assessment, analysis was conducted based on probability and the degree to which financial impact is increased or reduced. This was used to define significant sustainability risks and opportunities and to map them to the relevant ESG issues.
