Novatek confirms the establishment of supplier management system through the three major dimensions of economy, society (including human rights) and environment, evaluating the risks that the suppliers may face in carrying out sustainable development, so that appropriate countermeasures can be adopted. After the suppliers have obtained ESG system certification, they will be assessed based on the weighting and classified into three risk levels: low, medium and high. Suppliers with low risks (≧60%) will be selected as the candidate for priority procurement. On the contrary, for suppliers with high risks (≧30%), Novatek will provide guidance or assistance through arranging on-site audits or expert consultation. If the target is still not achieved, the procurement will be reduced or terminated. Assessment of supplier ESG management system is divided into three dimensions with a total of 100%. In 2025, the results of the ESG management system assessment for suppliers were in compliance with the low-risk supplier standard (≧60%), and there were no economic, social and environmental risks. In the future, the status of the suppliers in obtaining ESG system certification will be continuously monitored to ensure that the process can meet ESG management standards.

Note：Novatek has completed environmental and society (including human rights) impact assessments and identification for a total of 44 suppliers, and no significant potential negative environmental impacts were identified among them.

To gain a deeper understanding of the supplier situation, Novatek not only adheres to the “Responsible Business Alliance (RBA) Code of Conduct” but also actively implements RBA-related management systems and training programs within the Company. Additionally, Novatek requires its supply chain partners to conduct the "Self-assessment Questionnaire for Sustainable Development Management" covering five major areas: labor rights protection, occupational safety, environmental protection, compliance with ethical requirements, and management systems. This process helps Novatek identify supplier adherence to the “Responsible Business Alliance (RBA) Code of Conduct” and assesses sustainability risks. In 2025, a total of 44 suppliers responded to the sustainable development management questionnaire, representing a response rate of 100%, and the suppliers’ average scores on the “Self-assessment Questionnaire for Sustainable Development Management” were all above 97 points. In addition to the self-assessment scores, Novatek also reviewed the suppliers’ responses. If the responses to individual items were incomplete or if documents required additional supporting evidence, the suppliers were requested to provide explanations during regular meetings with Novatek so both parties could grasp the risks of suppliers. A total of 17 suppliers have accepted the RBA-verified audit process (VAP) and have corrected the deficiencies during the audit process. In its 2026 Sustainability Management self-assessment, Novatek incorporated Human Rights Due Diligence (HRDD) into its risk assessment framework by integrating human rights considerations into supply chain risk evaluations. The Company reviews and monitors supply chain human rights risk factors, including labor rights, child labor, and forced labor, to ensure that suppliers’ management mechanisms, preventive measures, and mitigation actions are effectively implemented and continuously improved. These efforts are intended to align the supply chain with the Company’s sustainability policies, thereby enhancing competitiveness, operational stability, and productivity, while supporting the steady expansion of international markets.

Adopting a sustainable development management approach, Novatek selected 10 key suppliersNoteto participate in assessments based on the Responsible Business Alliance (RBA) Code of Conduct. The Supply Chain Management Department, together with the ESG Committee, conducted social responsibility audits through both document reviews and on-site inspections. Audit results were classified into four rating levels: A, B, C, and D. In 2025, social responsibility audits were completed for all key suppliers, achieving a 100% completion rate, with all suppliers receiving an A rating, surpassing the original audit target of 90%. For improvement items identified during the audits, Novatek will continue to communicate with and provide guidance to suppliers while requiring corrective actions to be completed within designated timelines to ensure effective implementation of improvement measures. In addition to conducting social responsibility audits, Novatek also communicates its sustainable development management objectives through regular meetings and reviews supplier performance in areas such as energy saving and carbon reduction, renewable energy adoption, and carbon data governance. These efforts ensure that suppliers’ sustainability objectives remain aligned with those of Novatek, thereby strengthening the overall resilience of the supply chain.
