Stakeholders

01Communication with Stakeholders:

The Company follows the AA1000 SES Stakeholder Engagement Standard, using the five principles of "dependency, responsibility, influence, diverse perspectives and tension" as its assessment basis for the annual stakeholder identification exercise. In 2025, 46 stakeholder identification questionnaires were distributed and returned, completed by the Chairman, advisors and senior managers from every department. The results were consolidated by the project execution team, discussed and confirmed with each department at the monthly ESG working group meeting, and finally submitted to the Sustainability Development Committee for review and approval.

Based on the 2025 annual stakeholder identification results, JET Optoelectronics identified seven major stakeholder groups: employees, customers, suppliers, financial institutions, external verification bodies, shareholders and government agencies.

Compared with 2024, external verification bodies and financial institutions were newly added as major stakeholders this year. Because the Company is subject to regular audits of its quality and management systems, verification results directly affect quality management and customer trust, making external verification bodies highly influential for the Company. In addition, the Company maintains close dealings with financial institutions, which play an important role in working capital management and financial stability, and they were therefore included as major stakeholders.

Conversely, the Company's collaboration with academic and research institutions declined significantly in 2025 compared with 2024. Following identification and assessment, their level of influence was assessed as lower, and they were therefore removed from the list of major stakeholders.
