Sustainable Supply Chain Management
With the vision of becoming "the most trusted leader in sustainable resource circulation," ECOVE designates the Board of Directors as the highest decision-making body for sustainable supply chain matters. The Company's supply chain management is implemented in accordance with group policies, and material matters are reported to the Board of Directors on an ad hoc basis, including the setting of medium- and long-term goals and action plans for sustainable supply chain development. As Taiwan's largest environmental resource management company, ECOVE plays an important role in helping supply chain vendors to move towards sustainability by promoting sustainable supply chain management, so as to cope with future risks and opportunities, and enhance their sustainability.
Overview of Supply Chain
In order to provide better service quality, our supply chain vendors are primarily classified into three major categories: equipment suppliers, engineering contractors, and labor contractors. These major categories of vendors provide the necessary equipment, materials, maintenance assistance, improvement project implementation, and manpower support for ECOVE's operational facilities and stations. This includes various equipment parts, consumables (including chemicals and disposable supplies), and service providers for major maintenance, emergency repairs, equipment inspections, and labor workforce. By collaborating with various suppliers and contractors, we ensure stable operation of ECOVE's daily maintenance and successful completion of various project works. The number of manufacturers and the annual procurement amount indicate that, in addition to routine equipment maintenance materials and operational consumables, ECOVE's major procurement expenses are primarily focused on maintenance, updates, and repairs to keep the equipment running smoothly and on project contracts.

To ensure eective management, we further classify suppliers by tier. Suppliers whose annual cumulative transaction amounts fall within the top 80% and exceed US $300,000, as well as suppliers of 7 specific chemicals identified as material to scope 3 emissions, including quicklime, sodium bicarbonate, activated carbon, cement, chelating agents, urea, and ammonia water, are defined as tier 1 suppliers. Among them, suppliers with annual cumulative transaction amounts of US $2 million or more are regarded as First-Tier Key Suppliers. Suppliers that score below 50 in the SAQ assessment and fall within the bottom 5% of all suppliers are classified as high-risk suppliers, for whom onsite audits and control measures will be initiated.

Supply Chain Sustainable Development Strategy
In accordance with the sustainable development strategy of the supply chain of the Group's parent company, CTCI, COVE has invited suppliers to join us in our sustainable development strategy in the five aspects of "zero tolerance for unethical conduct", "full protection of employee rights", "safety first", "local procurement" and "biodiversity". We manage vendors' information through the supplier and subcontractor section of CTCI and also provide a whistleblowing platform, thereby establishing a comprehensive communication mechanism:

Strengthening the Culture of Sustainable Supply Chain Management
To implement sustainable supply chain management, the Company actively conducts training for procurement personnel to ensure that employees possess the professional knowledge and capabilities needed to respond to climate change and decarbonization trends. The 2025 training courses covered core topics such as greenhouse gas inventory (ISO 14064-1) and net-zero pathways, with total training hours reaching 108 hours. We not only enhanced employees' professional capabilities, but also translated sustainability criteria into concrete procurement practices.

Enhancing Sustainable Risk Management
Supplier Code of Conduct
ECOVE is actively committed to promoting corporate social responsibility and developing partnerships. We adhere to the principles outlined in the United Nations Global Compact, Universal Declaration of Human Rights, and the UN Framework and Guiding Principles on Business and Human Rights. In line with these standards on human rights, labor practices, environment, and anti-corruption, we have established the "ECOVE Supplier Code of Conduct." It is applicable to all suppliers, their subsidiaries, aliates and contractors, and ECOVE continuously requires suppliers and contractors to comply with sustainable standards related to labor and human rights, health and safety, environment, ethical practices and management system. The code applies to all suppliers, including their subsidiaries, aliated companies, and contractors, who provide goods or services to ECOVE. It mandates that all their business activities, including those of their subsidiaries, aliated companies, and contractors, fully comply with the provisions of the code as well as with the applicable laws and regulations in their respective jurisdictions.
Environmental and Social Criteria Screening Mechanism for New Suppliers
ECOVE recognizes that a sustainable supply chain is central to corporate resilience. We have established a rigorous screening mechanism for new supplier admission to ensure that our partners remain aligned with the Company's ESG values
○ Comprehensive Admission Review Tools
All new vendors are required to complete and provide the "Vendor Registration ESG Self-Assessment Form" and the "Supplier and Contractor Social Responsibility Consent Form" during the registration stage. These two documents cover key indicators related to environmental protection, such as pollution prevention and control and resource conservation, as well as social responsibility, including human rights protection, labor conditions, and occupational safety. They serve as the primary basis for assessing whether suppliers meet the Company's sustainability standards.
○ Vendor's Commitments to Corporate Sustainable Management and Net Zero
To address global climate change and align with the net-zero pathway, ECOVE has further required all new vendors to sign the "Vendor's Commitments to Corporate Sustainable Management and Net Zero" since 2023. This measure not only safeguards the long-term interests of shareholders and stakeholders, but also positions the pursuit of net-zero emissions as a shared responsibility. It aims to work hand in hand with suppliers to mitigate global warming and jointly build a living environment grounded in fairness, justice, sustainability, and resilience.
○ Binding Contractual Clauses
ECOVE translates its sustainability commitments into concrete management practices by explicitly incorporating "termination clauses" into all formal contracts. If Party B, the supplier, violates its corporate social responsibility policy and causes significant environmental or social impacts, the Company may terminate or rescind the contract at any time. Through this mechanism, we effectively strengthen suppliers' implementation of their social and environmental responsibilities, ensuring that sustainability management is not merely a formality.

Sustainable Supply Chain Management Mechanisms
○ Sustainability Risk Survey
In order to assess the sustainability risk situation of suppliers and the implementation level of sustainable practices, ECOVE has issued a self-assessment questionnaire (SAQ) on sustainability risk to first-tier suppliers on an annual basis since 2024. Through an investigation across seven dimensions, the potential risks of suppliers are identified. Based on the scoring results, suppliers who score below 50 points and fall within the lowest 5% among all suppliers are classified as high-risk vendors. Subsequently, on-site visits are arranged for these high-risk vendors to help them understand the importance of the survey items and provide improvement suggestions, such as avoiding the placement of clutter near fire safety equipment and promoting the conservation of water resources, in order to further manage risks.

The 2025 SAQ assessment identified 1 high-risk supplier. The assessment dimensions, risk factors, and corresponding response measures are presented in the table below. An on-site supplier audit was conducted in 2026 for the aforementioned supplier, and the supplier was required to implement corrective actions for identified deficiencies. This was undertaken to ensure that risks are eectively identified, controlled, and mitigated, while supporting the supplier in improving and enhancing its sustainability performance. Guidance and improvement recommendations were provided to the 1 high-risk supplier, achieving a completion rate of 100%. No supplier contracts were terminated.

○ Establishment of Supplier Sustainability Capabilities
To implement the management and control of sustainability risks among suppliers, the CTCI Group hosted the "2025 Fifth Taiwan Sustainable Engineering Forum" in November 2025. The theme of the forum is "Engineering Reimagined: Net Zero Carbon × Zero Waste × Zero Distance." Renowned experts and scholars, as well as key engineering and technical service providers, were invited to participate. The forum featured keynote speeches addressing trends related to COP29, ESG, and other topics, as participants explore new international sustainability trends and collaboratively creating value chain impact. To enhance suppliers' performance on ESG issues, ECOVE actively invites suppliers to participate in sustainability-related activities such as the Sustainable Engineering Forum, lectures, and sustainability newsletters. We continue to communicate and engage with suppliers to strengthen their sustainability literacy, promoting and deepening our concept of sustainable net zero throughout the supply chain. In addition, regarding suppliers of equipment and facilities, ECOVE plans to collaborate with external consultants in 2025 through a government guidance program to assist suppliers in conducting greenhouse gas inventories and providing recommendations for energy conservation and carbon reduction. For subcontractors, ECOVE's carbon seed personnel will assist suppliers in conducting greenhouse gas inventories and providing recommendations for energy conservation and carbon reduction, with the aim of significantly enhancing the suppliers' capabilities in sustainable carbon reduction.

○ Supplier Performance Evaluation and Audit Guidance
To assess the risks and competitiveness of the supply chain, ECOVE has established a mechanism for supplier evaluation, audit, and guidance. The evaluation, assessment, and audit of supplier and contractor supply and execution quality are conducted by cross-departmental teams comprising the Procurement Center, General Managers, the Occupational Health and Safety Management Department, and onsite team leaders. These teams evaluate and assess the quality of supply and execution by suppliers and contractors. On top of listing the quality of suppliers and contractors, costs, service standards, environmental protection, OSH, and technologies into the evaluation items to ensure their quality standards and safety and health, we also uphold the spirit of PDCA, requiring suppliers and contractors to rectify their deficiencies, and we provide necessary guidance in a timely manner, so that ECOVE's supply chain can maintain the best competitive state and mitigate the risk of operational disruptions. For equipment and material suppliers, a comprehensive evaluation is conducted to assess their commitment to compliance, delivery control, product quality, defect handling, and any disputed matters. This evaluation aims to examine the overall service and quality provided by the suppliers and serves as a basis for incentivizing them and providing improvement recommendations.
Supplier Audit/Evaluation Items

As for contractors, the Occupational Health and Safety Management Department conducts periodic audits and provides guidance at various construction sites. In terms of hazardous substance use, such as chemicals, gas, and fuel use, we require all suppliers to provide information on its components, safety information, and inspection report. Contractors will also be evaluated upon completion of each contract. A total of 205 evaluations were conducted in 2025, targeting vendors whose annual transaction volume exceeded a certain threshold. The "execute-feedback" mechanism was consistently promoted to assess vendors' actual performance and provide valuable insights for future vendor selection. If the evaluation results indicate non-compliance or unsatisfactory performance, the supplier will be coordinated for improvement. In case improvement has not been made, the vendor will be listed as an unqualified vendor. Upon review and confirmation from the responsible manager, it will be included on the "List of Unqualified Vendors" and contract will be terminated. In 2025, no suppliers were subject to contract termination or suspension following evaluation.

○ Contractor Visit and Communication
As the COVID-19 pandemic subsides in 2023, the supply of essential chemical agents for energy-from-waste plants has been properly arranged, and the risks associated with procurement and storage have gradually decreased. In addition to the evaluation of the contractor's construction results conducted by the supervisors from various units, the Company also enhances its positive influence on suppliers through procurement strategies. In 2025, the Company conducted on-site visits and in-depth discussions with key equipment suppliers and subcontractors. Through the process of factory inspection, a total of 27 evaluations and audits of contractors were conducted. The audit content covered aspects such as quality, safety, and compliance with regulations, and further guidance was provided to the vendors to implement corporate social responsibility policies. The evaluation results will serve as an important reference for future procurement and contracting decisions. In the future, the Company will continue to engage in diverse interactive methods to gain a deeper understanding of the internal operations of suppliers and contractors, and to ensure that their quality management meets the established standards. For example, site visit inspections when key equipment is sent out for maintenance, inspection of customized equipment and materials prior to delivery, and on-site operation audit during annual maintenance will be conducted by quality control and safety and health teams. Through on-site inquiries and visits, we propose recommendations and assist in improvements to enhance the management and execution capabilities of our partners. In addition, for the development of new suppliers, the Company conducts a comprehensive evaluation through on-site visits. This evaluation includes assessing contracting and management capabilities, facility conditions, manpower allocation, material management, quality control, and warehouse management. These assessments serve as a reference for trial orders and subsequent collaborations, ensuring supply chain stability and overall operational effciency.

○ Green Procurement and Local Procurement
ECOVE recognizes green procurement and green consumption as essential core values in promoting sustainable development within the Company. In response to the policy on green consumption, the concept of the green living circle has been introduced into the Company. This includes implementing green procurement of environmentally friendly products that are "low-pollution, energy-saving, and recyclable," as well as adopting other green services in daily life, such as green oce environments and green transportation. In both production and daily life, ECOVE aims to achieve energy eciency, carbon reduction, and a love for the Earth as sustainable development goals.
The Green Procurement Amount in the Past Four Years

Since 2014, the cumulative amount of green procurement has exceeded NT$970 million. The major operating bases of ECOVE are all located in Taiwan; ECOVE implements the local procurement policy in compliance with the parent company's sustainable supply chain development strategy. We believe that local procurement is conducive to local economic development and can minimize the negative impact on the environment by reducing carbon emissions from transportation. Except for special machinery components, ECOVE strives to source locally without aecting the stable operations, safety, and fairness of procurement. We screen local vendors with potential for the re-engineering of worn parts and equipment and provide them the opportunities to win trial orders and improve autonomy. The spare part engineering is mostly contracted to local vendors to reduce carbon emissions and waste and to create local employment and business opportunities.
