Material Issues


Material Issues

CT assesses the significance of the impacts of material topics on the economy, the environment, and people (human rights) through various communication and engagement channels and in accordance with the GRI Universal Standards 2021; these assessments provide the basis for sustainability planning and form the foundation for the disclosures in this report.

 

Identification and Classification of Material Issues

To enhance management policies and strengthen information disclosure, and taking into account regulatory trends and public attention to various sustainability issues, the CT ESG Verification Team resolved to continue the 15 sustainability issues from 2023. On January 9, 2026, it conducted an electronic survey of stakeholders on their level of concern regarding these issues. The questionnaire was posted on the Company website for investors and other stakeholders to fill out. To ensure that the information disclosed in the report genuinely addresses stakeholder expectations regarding the issues of concern, a total of 68 stakeholder questionnaires had been collected by January 30, 2026.

 

Through the materiality analysis assessment process, the material topics for 2025 were identified. It was found that the issues stakeholders focus on are largely the same as the material topics in 2024, namely: operational performance, ethical management, occupational environment safety and health, product quality, and personnel structure.

The score for ethical management increased. This change indicates that, influenced by issues in the overall industry environment, stakeholders are more focused on the legitimacy of corporate operations and regulatory compliance in sustainable operations. At the same time, with respect to climate issues, we will continue to strengthen risk assessment to ensure that environmental strategies are more aligned with the expectations of the public.


Century has also always upheld a business attitude of legality and compliance. In the future, it will continue to broadly solicit opinions from all parties, deepen communication and exchanges with all sectors, build two-way transparent dialogue channels, and repay stakeholders’ trust with substantive operating results, achieving stable growth in the Company’s long-term value.

Value Chain and Impact Assessment of Material Issues

 

Through internal discussions held by the CT ESG Verification Team, the affected parties and boundaries inside and outside the organization were defined and aligned with GRI topics; these definitions were confirmed by the Sustainable Development Committee and senior executives, and the direct and indirect impacts under the governance, environmental, and people (human rights) dimensions were identified for each material topic to respond effectively to stakeholders.

To enable stakeholders to better understand the impacts of each sustainability issue on the Company’s overall value chain, the environment, and society, five major sustainability issues of Century were identified, and the response strategies and positive and negative impacts of the material issues are explained.

Anti-competitive behavior


ž Compliance with regulations is the baseline for   enterprises, and through the effective implementation of regulations, the   Company continues to grow while maintaining a good reputation.

Custom Topic

ž By testing the Company’s products against   international standards, foreign manufacturers can cooperate with the Company   with confidence, and Taiwan’s technology will also gain recognition.

ž If the quality of steel structure welding and   offshore wind substructure equipment is abnormal, the Company’s reputation   will suffer, foreign clients will lose confidence in Taiwanese suppliers, and   natural calamities such as earthquakes could indirectly cause social   disasters.

Regarding labor safety issues,   the Company continuously improves through its occupational safety and health   management system, hazard identification, risk assessment, and occupational   health services, firmly believing that only in a sound environment can   employee health and safety be ensured.

ž If the workplace is unsafe, employees may suffer   injury or illness from health and safety hazards requiring treatment and   possible sick leave, or the impact may extend to the surrounding environment   and endanger the personal safety of local residents.
