Supalai Strengthens Cross-Functional Collaboration to Advance ESG Data Management and Sustainable Value Creation

“Sustainability is not the responsibility of any single department. It begins with the work we do every day and our collective efforts to transform operational data into meaningful insights that create value for the organization.”

Supalai Public Company Limited continues to strengthen the engagement of executives and department heads in advancing its Environmental, Social and Governance (ESG) initiatives. As part of its third-quarter management review, the Company presented an agenda item entitled “Sustainability Progress and Collaborative ESG Data Management for Organizational Value Creation” on 4 November 2026.

The session aimed to foster a shared understanding of the importance of sustainability and strengthen cross-functional collaboration in ESG data collection, performance monitoring, and continuous improvement.

Leadership Commitment: Translating Sustainability Policies into Action

Mr. Tritecha Tangmatitham, Managing Director, Chairman of the Sustainability Working Group, and Member of the Corporate Governance and Sustainable Development Committee, places strong emphasis on integrating sustainability into the Company's management practices. He encourages all departments to incorporate ESG considerations into their respective responsibilities and day-to-day operations.

To ensure continuity and systematic monitoring of sustainability initiatives, Mr. Tritecha has established a requirement for quarterly sustainability performance reporting. This reporting mechanism enables senior management to review progress, performance, challenges, and opportunities for improvement, while using the information to support management decisions, monitor implementation, and continuously enhance operations in alignment with the Company's sustainability objectives.

This approach demonstrates Senior Management Commitment to strengthening ESG Oversight and fostering Cross-Functional Accountability, ensuring that sustainability extends beyond corporate policies and is translated into practical actions and continuous organizational improvement.

Transforming Everyday Operations into Meaningful ESG Data

Supalai recognizes the importance of ESG Data Management and utilizes its corporate ESG Data Platform to systematically collect and maintain data from operational activities across departments.

The platform covers a range of sustainability-related activities, including community and social initiatives, innovation development, supplier capacity building, waste management, and Biodiversity Monitoring and Data Collection.

These data provide an important foundation for ESG Performance Monitoring, identifying opportunities for operational improvement, and supporting Sustainability Disclosure through the Company's Annual Registration Statement / Annual Report (Form 56-1 One Report), taking into consideration relevant topics under the FTSE Russell ESG Scores framework.

Strengthening Cross-Functional Collaboration in ESG Data Collection

As of 20 October 2026, 76% of the Company's functional divisions had participated in ESG data recording through the corporate ESG Data Platform. Key data collection activities included:

• 56 records of social and environmental initiatives submitted through the Company's Good Deeds application.
• 13 reported sustainable innovation initiatives, supporting data collection related to Sustainable Innovation.
• 1,024 waste management records, contributing to Waste Management data monitoring.
• 6 records of plant and animal species observations, supporting Biodiversity Monitoring and Data Collection.

These figures reflect progress in cross-functional participation and ESG data collection, providing a foundation for future monitoring, analysis, and improvement of sustainability-related activities. The number of records represents data collection progress and should not be interpreted as a direct measure of environmental or social outcomes.

Promoting Responsible Business Practices Across the Supply Chain

Another key focus of the meeting was the promotion of Responsible Supply Chain Management by encouraging relevant departments to engage with suppliers and business partners in acknowledging, signing, and complying with the Company's Supplier Code of Conduct.

This initiative forms part of Supalai's ongoing efforts to strengthen Supplier Engagement and promote Responsible Business Conduct, supporting continued collaboration and the development of responsible business practices across the supply chain.

Building a Culture of Sustainability through Collective Engagement

Supalai encourages executives and department heads to communicate ESG priorities and raise sustainability awareness among employees within their respective departments.

By fostering a deeper understanding of how individual roles and responsibilities relate to the Company's sustainability objectives, Supalai aims to integrate sustainability considerations into everyday business practices.

From efficient resource utilization and waste reduction and management to innovation development, community and environmental stewardship, and supplier collaboration, these activities provide opportunities for systematic data collection, monitoring, and analysis to identify areas for further operational improvement.

At Supalai, we believe that sustainability begins with the collective efforts of every department. When employees recognize the value of their contributions and work together to transform operational data into meaningful insights and opportunities for organizational improvement, sustainability becomes more than a corporate objective. It becomes an integral part of our organizational culture, growing alongside our business.
