Identification of 7 Major Categories of StakeholdersIn line with the GRI Standards and the AA1000 Stakeholder Engagement Standard (SES), we identified 7 key stakeholder groups through Sustainable Development Work Meetings: employees, shareholders/investors, customers, suppliers, government agencies, society, and the media. In addition, we gathered and analyzed the top 5 topics of concern for each of the 7 stakeholder groups and identified appropriate communication channels to integrate these concerns into the daily tasks and annual planning of our sustainable development efforts.

Selection of 24 ESG TopicsWe identified ESG topics relevant to Nanya Technology's operations from both internal and external perspectives. Our sources include international sustainability regulation standards (GRI Standards, ISSB, SDGs, TCFD, TNFD, SBTi, ESRS), industry-specific topics (RBA, SASB), sustainability ratings (DJBIC, CDP, MSCI ESG Rating, FTSE 4 GOOD Emerging Index), stakeholder communication processes, and internal business goals.
