Supply Chain Management

• The Company integrates the Procurement Plus digital platform as an enabler for ESG supplier screening from supplier onboarding. New suppliers complete 100% online sustainability self-assessments together with technical, innovation, financial stability, safety, occupational health, and environmental prequalification, particularly for suppliers in business development and construction of shopping centers and other buildings.

• The Company conducts supplier selection transparently, fairly, and without monopoly through three channels: (1) sealed-bid tendering and e-Auction for high-value work; (2) comparison of at least three suppliers, with technical capability and price value considered separately and clearly; and (3) an e-Catalog database of pre-registered products that have passed annual performance evaluation to improve operational speed.
• ESG decision criteria and scoring weights are based on the principles of good quality, good price, good service, correct terms, correct quantity, correct timing, correct source, and correct delivery location, together with limits on work volume per supplier to diversify risk. The Company has integrated ESG Self-Assessment as a core decision criterion, with scoring weights ranging from 30% to 100% depending on the type of goods and services. Additional scores are given to suppliers using construction materials with environmental product declarations (EPD) to support embodied carbon reduction in new construction projects.

• All suppliers that pass the screening and selection process must sign and comply with the Supplier Code of Conduct in writing to acknowledge the Company's sustainability agreements and criteria before formal registration.
• The Company uses this step to build sustainability alliances with critical suppliers and promote carbon disclosure collaboration and green procurement through environmental product declaration (EPD) or product carbon footprint data. This helps the organization better track and plan reductions in Scope 3 greenhouse gas emissions based on actual data without compromising supply chain agility.

For management efficiency, the Company classifies strategically important suppliers under the GRI and IFRS frameworks into two main categories:

• Critical Tier 1 Suppliers: assessed based on suppliers with high procurement value from spend analysis, strong financial stability, products or services that require strategic dependency because there are few market players, or a significant role in business continuity and crisis response.
• Critical Non-Tier 1 Suppliers: suppliers in the secondary supply chain (Tier 2+) that do not contract directly with the Company but provide raw materials or services to Tier 1 suppliers. The Company selects and identifies this group from suppliers with high significance to ESG risks or opportunities to expand governance coverage across the value chain.

The Company brings Critical Tier 1 Suppliers through an additional sustainability risk assessment process to screen and identify High Potential ESG Risk Suppliers based on three key risk factors:

1. Sector & Operational Risk, assessed based on suppliers whose operations are likely to create high negative environmental, social, and governance impacts according to business characteristics, such as labor-intensive construction site work or upstream raw material sourcing processes with high carbon emissions.
2. Contractual & Dependency Risk, assessed based on suppliers with contractual commitments longer than one year, where disruption or misconduct would have a high continuing impact on the business.
3. Transition Readiness, assessed based on suppliers that still lack sustainability policies or clear environmental management and circular economy systems.

For Critical Non-Tier 1 / Tier 2+ suppliers, or the secondary supply chain, the Company uses supply chain mapping for upstream raw materials with high embodied carbon, together with cascading requirements for critical suppliers to help oversee their own suppliers.

• The Company assesses goods and services from all suppliers every time goods and services are received by the purchasing or hiring unit. QR codes are scanned for every item ordered through the Company's procurement system for centrally purchased items to record statistics and conduct preliminary performance assessment.
• Critical Tier 1 Suppliers and Critical Non-Tier 1 Suppliers must undergo desk assessment or disclose selected sustainability information upon request from the central procurement unit and/or relevant units.
• Critical Tier 1 Suppliers assessed as high risk are subject to on-site assessments weekly or at intervals defined by the directly responsible unit, as well as random site inspections by senior executives of relevant functions. The assessments cover construction, production, service delivery, and supplier practices in fairness, safety, and human rights. Assessments follow laws, the Company's rules and regulations, the Supplier Code of Conduct, and sustainability delivery requirements, including health and safety, human rights, construction waste management, and grievance management.
• Specific groups of Critical Tier 1 Suppliers receive specialized assessments by external expert units, such as safety, traffic, negative environmental and biodiversity impacts, and green building standards, based on international standards and the Company's Supplier Code of Conduct.
• Certain Critical Tier 1 Suppliers receive in-depth assessment using primary data at supplier facilities to reduce risks in goods or service delivery and to consider potential for further collaboration and readiness for supplier development.

• The Company requires suppliers to prepare a Corrective Action Plan to improve issues that do not meet assessment criteria within the defined timeline and to continue corrective actions until the results are verified and confirmed. Failure to comply affects the supplier's evaluation score for maintaining supplier status with the Company in the following year.
• The Company defines clear disciplinary measures if suppliers neglect or violate agreements, particularly in safety. These measures follow the practices and score deduction criteria specified in the Performance Evaluation and Safety Rules form.

• Critical Tier 1 Suppliers that pass desk assessments or on-site assessments are benchmarked against other suppliers in the same goods and services category to further collaboration and elevate them from suppliers to long-term business partners. The objective is to reduce systemic risks in the supply chain while increasing capability, expanding potential, and promoting co-creation of innovation based on each supplier's needs and readiness in a tangible way.

• Suppliers that violate the Company's Supplier Code of Conduct, fail to comply with conditions, or do not pass assessments will enter the vendor and contractor blacklist consideration process. The status remains until the supplier successfully completes the corrective action plan, passes verification by the responsible unit, and receives approval for blacklist removal from the committee in accordance with the Company's procedures.
• The Company reviews supplier registers and accounts according to each function's defined cycle, together with annual consideration of supplier status in accordance with the corporate procurement policy.
