Identification of Stakeholders
MediaTek adopts the five major principles under the AA1000 Stakeholder Engagement Standard (SES), namely Dependency, Responsibility, Influence, Diverse Perspectives, and Tension, to measure the connection and level of impact between each stakeholder and MediaTek. Six major stakeholders have been identified as communication targets, including customers, industry/government/academia/research, employees, shareholders and investors, suppliers, as well as the general public/end consumers/media.
Analytical Flow for Materiality
| Benchmark analysis | Benchmarking analysis: Analyze and compile information on sustainability trends within the industry, major international sustainability rating agencies (such as S&P CSA, Sustainalytics, and CSR Hub), and international standards (GRI, SASB). |
| Issue identification | MediaTek has identified 23 ESG issues based on the results of the benchmarking analysis, combined with the ESG issues of concern to stakeholders. These remain consistent with the previous year. |
| Criteria for Material Topics Selection |
In 2025, MediaTek conducted a materiality assessment, identifying key topics through three dimensions: “assessment of impact on sustainability,” “assessment of impact on organizational operations,” and “stakeholder concerns.” These served as the criteria for selecting material topics. 【A】Assessment of impact on Sustainability: The ESG Committee’s working groups first conduct the assessment, with final confirmation by senior management. 【B】Assessment of impact on organizational operations: Ten internal senior managers evaluate the level of impact each sustainability issue would have on the Company’s operations and rank their importance accordingly. 【C】Stakeholder concerns: We survey key stakeholders to understand their concern for each sustainability issue. In principle, these surveys are conducted every two years. However, if a significant event or a major change in circumstances occurs, we will re-conduct the material topics screening during that year. The most recent screening was in 2024, and the next will be conducted in 2026. We approach these findings with careful consideration, using the latest results to confirm the outcomes of past measures and to set short-, medium-, and long-term goals, while proactively responding to stakeholders by establishing diverse engagement channels under the routine operation framework. |
| Sustainability Impact Assessment | After completing the survey, the ESG Committee further assesses how the Company’s operations, through these ESG issues, impact the economy, environment, and people / human rights. This includes evaluating the level of positive / negative impact and the actual / potential likelihood of occurrence, after which these issues are ranked based on their impact levels. |
| Confirming of Material Topics | The ESG Committee established the matrix of material topics using A) “Sustainability Impact Assessment” and B) “Organizational Operation Impact” as foundations, then finetuned the materiality ranking by considering C) “Stakeholder Concern Level.” Based on the communication and survey results, the ESG Committee’s working groups analyze root causes and develop corresponding improvement measures, which are presented to the CEO for final confirmation during the work meeting for the first half of the year. In line with the GRI 3- 3 reporting requirements for managing material topics, the corresponding measures, short-, medium-, and long-term goals, annual achievements, and management approaches for each material topic are outlined in the report. In 2025, MediaTek has 12 material topics in total. |
Material Topic Value Chain and Scope
MediaTek is an IC design company without large-scale production lines. It is situated at the forefront of the overall value chain, engaged in main business lines including R&D, design and sales of products, or customization commissioned by customers. Before the end product is completed, the back-end raw material procurement, manufacturing, packaging, and testing are executed by suppliers independently. The following table reviews the scope of impacts posed by each material topic on the value chain:
Assessing and Ranking the Impact of Material Issues
After material issues are finalized, each working group of the Sustainability Committee would evaluate the impact of 11 major issues on the economy, environment and people/human rights, including positive/negative impact and actual/potential likelihood. Impact is then ranked based on the results of evaluation, while the responding measures, short-, mid- and long-term goals, annual results and management guidelines are presented in the report, in accordance with the requirements of GRI 3-3 Management of material topics.
Impact Assessment
The materials issues are scored from low, moderate to high based on their impact on the economy, environment, people/human rights. Likelihood of occurrence is categorized into low, moderate, high and existing The results of assessment and summary done by each working group are as follows:
