Material Topics and Management Approach

Process of Materiality Analysis

Wistron conducts its materiality analysis annually. The Company follows GRI Universal Standard 2021’s GRI3: Material Topics 2021 while integrating the evaluation methodology of the impact on the economy, environment and society developed by Value Balancing Alliance (VBA), Harvard Business School’s Impact-Weighted Accounts project and London Benchmarking Group (LBG) and incorporating European Financial Reporting Advisory Group (EFRAG)’s Double Materiality principles to build its impact-based materiality analysis process to identify material topics. The analysis result was passed by the board’s resolution, which determined 17 sustainable issues as the material topics for the Company’s 2024 Sustainability Report. These material topics were further integrated into the Wistron's Enterprise Risk Management (ERM) process to identify risk factors, frequency, and severity, and to develop risk mitigation measures. The results of the materiality analysis were verified by a third-party to confirm the disclosure boundaries and scope of information, which were based on the foundation for setting long-term sustainability targets. 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.
 
Survey 1
Internal/external stakeholder concerns
Survey 2
Impact to the organization’s operations (inward impact)
Survey 3
Sustainable development impact
(outward impact)

Internal/external stakeholder concerns

Wistron conducted questionnaires to survey 7 types of internal/external stakeholders regarding their concerns towards ESG topics. Totaling 406 stakeholders that have participated in this questionnaire survey. 
  • Customers (30 participants)
  • Employees (168 participants)
  • Suppliers (257 participants)/ Contractors (29 participants)
  • Shareholders/investors (19 participants)
  • Government/Competent authorities (6 participants)
  • Non-profit organizations/Communities (20 participants)
  • Media (3 participants)

Impact to the organization’s operations (inward impact)

When driving business sustainability, Wistron believes in linking ESG promotion with the core of Wistron’s business development. A total of 6 executives participated in the survey. Impact of each sustainable issue on the Company’s operations was assessed from the perspective of financial materiality, with the topics’ materiality being ranked accordingly.
  • Revenue
  • Employee cohesion
  • Customer satisfaction
  • Operational risk
  • Brand image

Sustainable development impact (outward impact)

Wistron invited its internal core teams responsible for its ESG promotion - a total of 27 supervisors and employees to participate in its sustainable development impact evaluation, using Impact Valuation to evaluate the positive/negative and potential/actual impacts and their extent (such as scale, scope or irremediability), likeliness and other factors. They also established a threshold for the impact severity and likeliness. Any impact that meets that threshold will be categorized as a significant impact caused or contributed to by Wistron and ranked ESG issues based on these impacts; meanwhile, Wistron also integrated the result of their regular impact monetization analysis result and selected influential and material topics based on the monetization values.

  • Wistron Sustainability Impact Analysis – Monetary
 
1.    IRIS (Impact Reporting & Investment Standards) is a generally accepted impact accounting system developed by the Global Impact Investing Network (GIIN) for measuring the social, environmental, and economic performance of enterprises. Use of IRIS also facilitates the comparison of impact information.
2.    Externalities refer to the positive or negative impacts of Wistron’s operations and our interactions with various forms of capital on human well-being, where the company does not directly reap the benefits or bear the costs. Wistron evaluates these impacts using frameworks such as the Natural Capital Protocol, Social & Human Capital Protocol, and ISO 14008:2019 for environmental impacts and related considerations. These are integrated with methodologies from Harvard Business School’s Impact-Weighted Accounts (IWA) and the Value Balancing Alliance (VBA) to convert various environmental and social externalities into a standardized monetary value.
3.    Gross Value Added (GVA) measures the difference between intermediate inputs and final outputs throughout operations. It reflects the benefits generated for various stakeholders by accounting for both original inputs and public expenditures.
4.    To calculate the output value of our supply chain, Wistron adopted an Input-Output Model, which captures the economic impacts driven by procurement demands across the industrial chain, as well as associated environmental issues, job creation, and wage income. Data sources include the Input-Output Statistics Report (DGBAS, 2025), Green National Income Accounts (DGBAS, 2021), Energy Balance Sheet (Bureau of Energy, 2021), and the EXIOBASE 2 database. Analyses for previous years were retrospectively adjusted to align with updated input-output data published by DGBAS.
5.    Environmental externality impact factors include GHG emissions, air pollution, wastewater, waste, and water consumption. These factors are monetized based on the social cost of carbon, human health impact, and ecosystem damage, with reference to US EPA (2016) and OECD (2012) guidelines.
6.    The social cost of occupational accidents is calculated using the employees’ willingness to pay to avoid incidents and the medical resources consumed due to such events, referencing methodologies from UK HSE (2017), Jiune-Jye Ho (2005), and the Institute of Labor, Occupational Safety and Health (2013).
7.    Health risk management involves early identification of individuals at risk of high blood pressure, high cholesterol, high blood sugar, and obesity through regular health screenings, followed by customized interventions to reduce the risk of cardiovascular diseases. Coefficients are drawn from WHO (2008) and Chieh-Hsien Lee (2009).
8.    Employability and future earnings evaluate the impact of internal training programs that enhance employees’ professional skills and knowledge, which improves productivity and career development. The reference source is VBA (2021). Since productivity improvements from training are already reflected in financial statements, this indicator isolates the gains in well-being from increased income following job transitions.
9.    Social engagement value is calculated using the London Benchmarking Group (LBG) framework for community investment, which quantifies the benefits of philanthropic activities by accounting for cash donations, resource donations, time, and management costs.
10.    Products and services focus on notebooks, desktop computers, monitors, and VoIP phones. The indirect economic value created is assessed by analyzing the supply-demand relationship between product sales and client industry output, along with environmental benefits and external costs arising from eco-friendly product design, usage, and end-of-life disposal.
11.    To account for differences in economic conditions across countries, valuation coefficients are adjusted based on regional Purchasing Power Parity (PPP)-adjusted Gross National Income (GNI). Adjustments are also made for inflation and exchange rates to normalize all monetary values to 2018 as the base year, following methodologies outlined by OECD (2012) and PwC UK (2015).
12.    The "social" dimension of impact refers to interpersonal networks that foster collaboration within and between groups. These networks share norms, values, and consensus (Social & Human Capital Protocol, 2019). The "environmental" dimension encompasses the stocks of renewable and non-renewable natural resources (e.g., plants, animals, air, water, soil, minerals) and the flow of benefits or services they provide (Natural Capital Protocol, 2016). External employees refer to workers employed by suppliers or contractors, while internal employees refer to Wistron employees.

Prioritizing material topics

Based on the screening principles outlined in Step 3 above, each issue was evaluated and ranked according to its level and breadth of impact. Ultimately, 17 material topics were identified and signed off by the Board of Directors.
