Stakeholder Communication
Given that stakeholder identification and communication are fundamental to implementing corporate sustainability, Taiwan Numerical Powers adopts five principles of “dependency, responsibility, influence, diverse perspectives, and tension” under the AA1000 Stakeholder Engagement Standard (SES) for identification. Referring to the GRI Standards and other industry peers, the Company's potential stakeholders include shareholders, banking institutions, government organizations, employees, customers, business partners, suppliers, community/local groups, non-governmental organizations (NGOs), social welfare organizations, and academic/industry–academia collaboration units. Through reviewing the results of interactions with relevant stakeholders from 2023 to 2025, as well as discussions with external experts and internal company members, these entities were confirmed as the Company's important stakeholders for 2025.
Through the kick-off meeting, the Company discussed with external experts and referenced the identification results per the GRI Standards. After the President decided on the stakeholder categories, the final identification results were reported to the Board of Directors. The five identified stakeholder groups are customers, employees and other workers, shareholders/other investors, suppliers/contractors, and the government.
