Governance for Sustainability

Sustainable Development Committee Organizational Chart

Edison Opto places strong emphasis on corporate social responsibility and has continuously advanced its sustainability practices since 2017. To strengthen sustainability governance, the Board of Directors serves as the highest decision-making body. On June 5, 2025, the Board approved the establishment of the Sustainability Development Committee, under which a Sustainability Working Group was formed.

The Working Group is responsible for proposing and implementing sustainability policies, systems, and specific action plans. It reports execution results and future plans to the Board at least twice a year. For major issues, proposals must first be reviewed by the Sustainability Development Committee and then submitted to the Board for approval before implementation.

The Sustainability Development Committee consists of five members, including two directors, with the Chairman serving as the convener and chairperson. The Committee convenes at least once annually and is responsible for reviewing Edison Opto’s sustainability policies, systems, and implementation targets, as well as overseeing related management guidelines and action plans. It also supervises sustainability information disclosure and reviews the Sustainability Report.

In 2025, the Company held a total of two Sustainability Development Committee meetings, and all resolutions passed by the Committee were subsequently submitted to the Board of Directors for discussion and approval. In addition, to strengthen corporate governance, the Company reported on the progress of sustainability initiatives to the Board twice in 2025.

The Sustainability Working Group serves as the dedicated unit for sustainability development, responsible for formulating and implementing sustainability policies, systems, management guidelines, and specific action plans. It is convened by the (Deputy) General Manager, Plant Manager, and Chief Sustainability Officer.

The group is structured into four functional divisions: Business Management, Social Engagement, Environmental Sustainability, and Green Products. In accordance with the Sustainability Practices Code, risk management regulations, and related policies, the group identifies, evaluates, manages, and monitors risks associated with environmental, social, and governance (ESG) issues that may impact the Company’s operations. Preventive measures are also implemented to minimize potential losses arising from such risks.

An Executive Secretary supports the Sustainability Working Group in daily operations, including data collection and consolidation, progress tracking, and cross-functional communication.

The following outlines the roles and responsibilities of the four divisions: Business Management, Social Engagement, Environmental Sustainability, and Green Products.
