Procurement Management Strategies and System
In 2022, PTG established a sustainable supply chain management strategy with a focus placed on comprehensive supply chain management, covering the selection of potential business partners and ethical business conduct. With the strategy, the Company will be able to adapt to changes that affect sustainability and empower business partners to sustainably conduct their business and grow together in the long run. There are five strategies to be implemented as follows:
The following five strategies are thus executed.
1. Vendor Management Standard Provide a vendor management standard applicable to acquisition, potential assessment, retention, and risk management to ensure that the procurement process is carried out effectively and respond to higher product demands, as well as to reassure that products and services delivered meet the required quality and are in compliance with policies, regulations, operational standards, and the objectives of the company.
2. Accountable vendor procurement and assessment The company works on acquiring and recruiting productive and credible vendors while also adhering to assessment criteria to maintain the Approved Vendor List. In addition to product quality/safety, pricing, and quality of deliverables, the company also places importance on the management of ESG issues of the vendors, which encompasses environmental impact management, good labor practices—such as prohibitions on child labor, fair wages and benefits, preventing forced labor and human trafficking, respecting freedom of association and collective bargaining, and ensuring harassment-free and non-discriminatory practices—as well as compliance with applicable laws and regulations to sustainably enhance the performance of business operations, both of the company and the vendors.
3. ESG Risk Management Outline a vendor ESG risk assessment, of which the criteria will be based on the nature of each business field, and also actively evaluate the vendors and monitor their operations.
4. Cost Optimization Committed to providing an excellent work process by consolidating data management to systematically classify products and vendors through technology usage to enhance each step of the procurement process. Moreover, the company prioritizes transparency, accountability, cost reduction, and minimization of errors.
5. Relationship Development Develop strong and trusting relationships with vendors while also identifying business growth and expansion opportunities, both in terms of innovation and the development of sustainability potential through knowledge exchange between organizations.

Collaborative Development Plan with Suppliers
Following the completion of the ESG assessment for suppliers, PTG has developed a joint corrective action plan with suppliers whose ESG performance does not meet PTG's assessment criteria. Additionally, there is sharing and support of crucial practices for suppliers through the PTG Knowledge Sharing activity: ESG for Sustainability through the Supply Chain. This event is conducted online via video conferencing to facilitate convenient access for all suppliers. The objective is to encourage suppliers to operate in accordance with various sustainability standards that can be benchmarked against competitors in the market. Moreover, there is support for suppliers' promotion and improvement of social, governance, and environmental aspects through both remote processes and on-site interventions. For example, during ESG assessments, PTG provides recommendations and suggestions to enhance suppliers' ESG operational processes.
