Annual performance

The Company has continued to demonstrate long-term achievements across three key areas—employee development, environmental and occupational safety management, and social care—building a sustainable enterprise characterized by both resilience and responsibility. 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. By fostering a culture of continuous learning, employees are able to remain agile and innovative in a rapidly changing industry environment.

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. Overall, the Company has achieved balanced and tangible sustainability outcomes across talent development, environmental protection, safety, and social contribution, working together with society to build a better future.

We value the safety and hygiene of the working environment for our employees.

Occupational safety and health education, training, and communication are an important foundation for strengthening safety culture. All Company employees are required to receive general in-service occupational safety and health training every year, and new employees are also required to complete general occupational safety and health courses upon onboarding so that they fully understand the Company's safety requirements, management systems, and their own rights and obligations.


The Company plans multi-dimensional professional training courses for different scenarios to enhance employees' ability to identify potential hazards and respond appropriately. For positions involving higher risk, advanced professional training and on-site drills are additionally arranged to strengthen practical operating skills and emergency response capabilities.


Education and training are delivered through various formats, including in-person classes, online learning, external professional training, and scenario-based drills. Multilingual learning materials are also provided as needed to help employees of different nationalities understand the content. After each course, learning effectiveness is evaluated through tests and questionnaires, which serve as the basis for rolling revisions and optimization of training content to ensure training quality and practical effectiveness.


In addition, contractors and other external workers are required to complete safety and health education and hazard notification before entering the plant, and they receive necessary safety supervision and reminders during operations to ensure that all personnel entering the workplace possess basic safety knowledge and risk awareness, thereby jointly preventing occupational accidents.


In 2025, a total of 53,165 participations completed occupational safety and health education and training, with total training hours reaching 282,198 hours. We will continue to deepen safety awareness among all employees and foster a safety-first corporate culture through systematic and diversified education and training mechanisms.

Supplier Occupational Safety and Health Audits


In addition to requiring all major operating sites within the Company to strictly comply with local occupational safety and health regulations, Sunon also requires suppliers to follow the Company's Supplier Code of Conduct, which explicitly sets out occupational safety and health requirements. Each year, the Company continues to conduct occupational safety and health audits of key suppliers to confirm whether any non-compliance exists and to investigate the number of occupational injuries and occupational disease cases occurring during the year, thereby assessing deficiencies in suppliers' occupational safety and health management. For non-major deficiencies, the Company proposes improvement items and recommended measures and grants suppliers a one-month improvement period, after which a re-audit is conducted to ensure that workplace risks have been effectively controlled. All suppliers successfully passed the Company's occupational safety and health audits during the reporting year.
