For the purpose of corporate governance, integration of procurement resources and the implementation of Walsin Lihwa's procurement culture (sunshine, sustainable, professional, efficient), the company established a procurement center in October 2022 with the goal of establishing a standardized and transparent procurement process. We use information system tools for procurement management, select long-term strategic partners, and work with them to establish a sustainable supply chain, and guide suppliers to develop the common value of corporate social responsibility.

In order to implement effective supplier management, Walsin Lihwa identified 173 key suppliers based on important raw materials, equipment and construction contracts, and waste disposal projects according to the principles of procurement amount, importance, influence, and uniqueness. This is an increase of 8 companies from 2021, accounting for 62.66% of total purchases. These suppliers will be partners in the joint promotion of a resilient supply chain and corporate social responsibility.

We work together with our suppliers in the pursuit of corporate sustainability and growth. We continue to engage in local procurement and to promote local economy and reduce energy consumption in transportation. 16.31% of procurements made by our key suppliers in Taiwan are sourced from local suppliers (key metals and minerals in Taiwan are mostly imported from abroad); 37.51% of procurements made by our key suppliers in mainland China are sourced from local suppliers; and 41.44% of procurements made by our key suppliers in Malaysia are sourced from local suppliers. Overall, 29.58% of our key suppliers are local suppliers, a decrease of 2.04% compared to 2021.

In order to reduce the impact of our products on the environment, we are committed to green procurement. The Wire and Cable Business recycles old wood, iron shafts, and seal plated for reuse to reduce the number of new products procured. The Stainless Steel Business actively uses recycled raw materials such as scrap steel, scrap copper, and nickel/chromium crude iron. In 2022, Taiwan plants invested NT$10.37 billion in green procurement, accounting for approximately 12.80% of the overall procurement ratio in Taiwan.

To strengthen and implement sustainability of suppliers and to work with partners to build up the strength of the company, Walsin Lihwa not only evaluates suppliers' quality, completion/ delivery time, pricing, service/communication, and coordination to ensure that suppliers can meet the requirements, but we also strengthen the supplier management mechanism by requiring suppliers to fill out the "Supplier's Undertaking" to enhance supplier awareness. In 2022, a total of 161 key suppliers in the Wire and Cable Business, Stainless Steel Business, and Real Estate Business were the targets for evaluation. These suppliers would evaluate their own management status and fill out a new version of the "Corporate Social Responsibility (CSR) Sustainability Self-Assessment Form". The assessment items include economic (sustainability management, supplier management, trade secret protection), social (human rights, health and safety), and environmental (management systems, greenhouse gases, air pollution, waste management) aspects. The sustainability management of suppliers is analyzed based on results of the self-evaluation form, and then the probability, level of impact, and warning mechanisms for incidents that will threaten its sustainability are assessed, identifying the threat and impact of incidents that threaten the sustainability of key suppliers on Walsin Lihwa's operations.

1. Regularly hold communication and discussion meetings to support suppliers' growth and improve their business quality.
2. Continue to carry out 100% pre-work safety education and training for existing contractors.
3. Onsite checking of suppliers' practices in management, social and environmental aspects, and continue to improve the assessment and checking of deficiencies.
4. Establish risk identification mechanisms

Sustainable Supply Chain Management Courses have been held since July 2022, so that we can improve sustainable supply chain management. We will also establish a supply chain sustainability onsite review mechanism and supply chain sustainability risk assessment mechanism, in order to improve the plant and procurement unit employees' sustainable supply chain promotion and management abilities.

We also strengthened the cross-type product knowledge of our sales staff so that customers can purchase different types of products through one single sales window, which improves the problem of having to deal with multiple windows in the past and enhancing customers' trust in sales staff.
