To implement the Company's sustainable development initiatives and enhance governance effectiveness, HLC's President is responsible for approving ESG-related policies and execution plans, while tracking progress and results through monthly regular meetings to promote sustainable development. Any critical material issues may be reported to the Board of Directors as deemed necessary; however, there were no material sustainabilityrelated matters required to be reported in 2024. Subsequently, in June 2025, the Board of Directors approved the establishment of the "Sustainable Development Committee" and formulated the "Sustainable Development Committee Charter" as its basis for operation. This committee is responsible for formulating the Company's overall sustainability direction, overseeing execution plans, reviewing sustainability reports and information disclosure, and ensuring that the Company's ESG goals are achieved and aligned with the core corporate strategy.

The Sustainable Development Committee is convened by the Chairman, with members including the President, one Executive Vice President, one Vice President, and one Assistant Vice President, totaling five members. The committee has dedicated (or concurrent) promotional units that practically advance relevant tasks through three functional teams and a team coordinator, including:

Sustainable Environment Team (E): Focuses on climate change response, resource efficiency improvement, and environmental legal compliance to promote environmental sustainability management.

Social Welfare Team (S): Strengthens human rights protection, community engagement, and social investment, to foster a corporate culture of social inclusion.

Corporate Governance Team (G): Covers legal compliance, employee performance, education and training, and stakeholder communication, to promote governance transparency and responsible operations.

Sustainability matters are promoted through an inter-departmental collaborative mechanism, with the Management Department serving as the overall coordinator for the teams. It coordinates and integrates internal resources from departments, such as the Inspection and Maintenance Operations Department, Customer Service Department, Planning Department, Information Technology Department, Finance Department, Occupational Safety and Health Office, and Audit Office. It is also responsible for compiling sustainability information and ensuring the completeness and transparency of information disclosure, presenting data relevant to stakeholders in accordance with international standards. Each team engages with stakeholders based on their functions to keep abreast of external expectations and risk opportunities. All sustainability operations are regularly reported to the Sustainable Development Committee to ensure that sustainability efforts are closely aligned with the Company's overall development strategy, facilitating achievement of sustainability goals.
