First, in terms of talent development, employees participated in an average of 47 hours of education and training per year, reflecting the Company’s commitment to enhancing employees’ professional knowledge and career capabilities and to strengthening organizational competitiveness through systematic training mechanisms.

In the areas of environmental protection and occupational safety, all production sites in Taiwan and worldwide have obtained ISO 14001 Environmental Management System and ISO 45001 Occupational Health and Safety Management System certifications. This indicates that the Company has established a comprehensive EHS management framework, continuously improving process efficiency, reducing environmental impacts, and ensuring that all employees work in a safe and healthy environment. Consistent implementation across the global supply chain and manufacturing sites further demonstrates the Company’s commitment to unified management in its international operations.

At the same time, the Company has long invested in social welfare. From 2018 to 2025, the “Inspirational Care Activity” reached a cumulative total of 13,750 households, providing companionship and support to disadvantaged families through concrete actions. This sustained social engagement not only reflects the spirit of corporate citizenship, but also extends the Company’s positive impact into communities, creating broader and lasting value.
