The Board of Directors of DEPO consists of ten directors. Candidates for directors are nominated by the Board of Directors. After the Board of Directors reviews the qualifications of independent director candidates, the Board of Directors submits them to the shareholders' meeting for selection. Diversity, independence, and professionalism are used as the criteria for evaluation. In order to achieve the ideal goal of corporate governance, all directors arrange continuing education courses each year. In 2023, all directors reached the required continuing education hours. The functional committees are the Audit Committee, Remuneration Committee, and Sustainable Development Committee, which assist the Board of Directors in fulfilling their supervisory duties and the Company's sustainable development policy. Each committee is required to hold regular meetings and report to the Board of Directors on their activities and resolutions.

The Board of Directors is the highest governing body of DEPO. The Chairperson chairs and leads the Board of Directors in executing and supervising the Company's various businesses. The General Manager formulates various business plans based on the market conditions and industry situations. To avoid a conflict of interest, the Chairperson and the General Manager must be different persons; the Board of Directors does not vote on a proposal involving a conflict of interest that may affect the interests of the Company and shareholders. A total of five board meetings were held in 2023. Please refer to the Company's annual report for the relevant agenda .

Starting from 2024, DEPO will issue a sustainability report annually in accordance with the Rules Governing the Preparation and Filing of Sustainability Reports by TWSE Listed Companies. The Execution Office under the Sustainable Development Committee collects and aggregates information relating to the aspects of environment, social, and corporate governance to be disclosed in the Sustainability Report. After the report is completed, it will be delivered to a third-party unit for assurance and submitted to the Board of Directors for publication after resolution adopted by the Board of Directors.

In the "Corporate Governance Best Practice Principles,” DEPO has stipulated that the composition of the Board of Directors shall consider diversity, and there is no restrictions based on gender, race, and nationality. In addition to possessing the knowledge, skills, and accomplishments necessary for the performance of duties, the composition of the Board of Directors must also comply with independence standards. The Board of Directors has four independent directors. Except for Chairperson Hsieh, Hsiu-Chi and Director Hsu, Shu-Ming, who are spouses to each other, all other directors are not spouses or relatives within secondary kinship, so they are sufficiently independent.

DEPO has established the "Rules for Performance Evaluation of Board of Directors" to conduct a performance evaluation of the Board of Directors once a year. The evaluation scope includes the entire Board of Directors, individual Board members, and functional committees. The corresponding evaluations are adjusted for different evaluation scopes, and the internal self-evaluation is the primary method used for the evaluation. The 2023 performance evaluation of the Board of Directors and functional committees has been completed and submitted to the Board of Directors on March 14, 2024. The performance evaluation results are used as a reference for individual directors' remuneration and nomination for re-election.

Risk management plays a crucial role in operations. Only by effectively responding to various risks, the sustainability of operations can be ensured.
