Social Co-prosperity

To safeguard employees' financial security after retirement, the Company contributes retirement funds in accordance with the law and administers retirement systems and contributions in line with the relevant laws and regulations of each place of operation, ensuring that employees' rights and interests are properly protected.

In Taiwan, the retirement system is administered in accordance with the Labor Standards Act and the Labor Pension Act. All current employees have elected the new pension scheme, under which the Company contributes 6% of employee salary each month, as required by law, to individual labor pension accounts at the Bureau of Labor Insurance to accumulate employees' personal retirement funds. For the small number of employees who still retain seniority under the old pension scheme, the Company continues to contribute 2% of employee salary each month, as required by law, to the Labor Retirement Reserve Account at the Bank of Taiwan, from which retirement payments are made when retirement conditions are met.

Overseas operating sites establish retirement protection systems in accordance with local laws and regulations. For example, in China, employees are enrolled in pension insurance and related social insurance contributions are made in full in accordance with the law. Other operating sites also contribute retirement funds or social security payments in accordance with local requirements to ensure that employees' retirement rights and interests comply with local regulatory requirements.

In addition, when employees reach retirement age, the Company not only handles retirement applications and related payments in accordance with the law, but also expresses appreciation for their long-term dedication and contributions, reflecting the Company's respect and care for employees' career journeys.

To share the long-term results of the Company's operations with employees and strengthen talent retention and cohesion, the Company has implemented an "Employee Stock Ownership Trust Plan" that encourages employees to participate in the Company's growth as shareholders. The plan is voluntary. Employees may contribute a fixed amount from their monthly salary based on personal preference, and the Company contributes an equal amount, with both contributions deposited into a stock ownership trust account. The trust account is managed by a professional financial institution, which regularly purchases Company shares in the name of the trust, helping employees build longterm shareholding in the Company.

Through this co-contribution mechanism between the Company and employees, the plan not only enhances employees' willingness to hold shares over the long term, but also enables them to participate meaningfully in the results of the Company's operations, accumulate personal assets, and build a partnership with the Company based on shared value and mutual benefit. Going forward, the Company will continue to optimize the design of the plan in light of operating performance and market conditions, strengthen its effectiveness in attracting and retaining talent, and further consolidate the foundation for sustainable corporate development.

Under a comprehensive institutional framework, the Company continues to support employees through important stages of life by investing tangible resources. In 2025, marriage- and parenting-related subsidies and support measures benefited nearly 200 employee participations, with total investment exceeding NT$460 thousand. The use of related leave and flexible working hour arrangements also exceeded 70 thousand hours in total, demonstrating employees' strong demand for and trust in these family-friendly measures.

We firmly believe that a company's warmth is reflected in its understanding of and support for employees' life needs. Through concrete actions and ongoing investment, the Company not only shares in the joy of employees building families and careers, but also serves as a strong and dependable source of support at different stages of life through stable and long-term support mechanisms, jointly creating a more secure and mutually supportive workplace environment.

Sunon's operating sites establish childcare-related systems and leave arrangements in accordance with local laws and regulations, and eligible employees may apply based on their individual needs.

In Taiwan, the Company provides 8 weeks of paid maternity leave, 8 days of paternity leave and paternity check-up leave, as well as a flexible parental leave without pay system. Employees may apply before or after childbirth based on their personal needs. During parental leave without pay, relevant subsidies and allowances may be claimed for the first six months, and both parents are eligible to apply. The Company also proactively follows up with employees 30 days before the end of parental leave without pay to inquire about their intention to return to work. Going beyond legal requirements, the Company provides employees with children under three years old with one hour of paid childcare leave per day to help them balance work and family caregiving responsibilities, demonstrating the Company's long-term commitment to a family-friendly workplace and childcare support.

In China, the Company implements childcare leave systems in accordance with local regulations and provides employees with children under three years old with 10 days of paid childcare leave per year in response to policy requirements in different regions and to support employees' family care needs.

In the Philippines, the Company provides a total of 17 weeks of maternity and childcare leave in accordance with local regulations, safeguarding the rights of female employees during pregnancy and childbirth and supporting them in balancing family and career development.

In 2025, the return-to-work rate for employees in Taiwan who applied for parental leave without pay was 100%, and the retention rate one year after returning to work was also 100%.

The Company conducts health risk assessments based on the working environment and operational characteristics of each plant, identifies noise, organic solvents, and other potential hazard factors, and adopts engineering improvements and personal protective measures to reduce the risk of employees being exposed to hazards during operations. For employees working in special operating environments, dedicated health examinations are arranged in accordance with regulations and operational risks, and designated personnel regularly track examination results, implement graded management and follow-up care for abnormal findings, and help employees prevent and treat occupational-related diseases at an early stage.

The Company also works with external medical institutions and professional organizations to provide employees with occupational disease testing, physician consultation, and treatment services. Certain operating sites have medical rooms or health centers staffed by professional medical personnel to provide emergency treatment for injuries and illnesses, health consultations, and assistance with medical care, thereby strengthening timely health support mechanisms.

With respect to personal health promotion, the Company provides pre-employment health examinations for employees in Taiwan and regularly arranges general health examinations at a frequency exceeding legal requirements. By comprehensively evaluating employee age structure, historical health examination data, and common chronic disease risks, the Company identifies physical and mental risk factors such as prolonged sitting, lack of exercise, unbalanced diet, and psychological stress. To address these issues, the Company organizes health seminars, specialist physician consultations, and fitness promotion activities to help employees establish sound health concepts and healthy lifestyle habits, and integrates health management into daily workplace culture through diversified communication efforts.

The Company conducts comprehensive annual health examinations to help employees proactively understand their personal health conditions. Health examination teams from medical centers travel to various office locations to provide convenient nearby services, lowering participation barriers and improving accessibility. In 2025, a total of 542 employees in Taiwan participated in health examinations, representing a participation rate of 98.7%, demonstrating employees' strong commitment to health management.

Each site plans examination items based on working environment and job characteristics. In addition to complying with regulatory requirements, the Company provides examination frequency and item subsidies exceeding legal requirements and includes screening for common chronic diseases and major illnesses to strengthen preventive medical benefits. The Company also enhances employee participation rates and health awareness through diversified communication mechanisms.

After annual health examinations are completed, health management personnel at each plant arrange follow-up consultation services and professional physicians provide one-on-one explanations of examination reports. For employees whose results show major abnormalities or high risk, the Company provides assistance with medical treatment and ongoing follow-up care, together with appropriate medical advice and health guidance, to ensure that employees can take action early and receive proper care.

To enhance employees' health awareness and cultivate healthy lifestyle habits, the Company continues to promote diversified health promotion activities, including health awareness campaigns, health seminars, on-site physician consultations, and public welfare blood donation drives, encouraging employees to proactively care for their own health, reduce potential health risks, and foster a positive and caring workplace culture.

Health seminar topics over the years have covered stress adjustment, nutrition and diet, chronic disease prevention, and first-aid knowledge. Professional physicians are also arranged to provide one-on-one consultation services so employees can receive professional advice and guidance on personal health issues. Through regular health awareness campaigns and health education communication, the Company strengthens employees' understanding of common health issues and enhances their self-care capabilities.

In addition, the Company organizes public welfare blood donation activities, encouraging employees to give back to society through concrete action. While caring for the health of others, these activities also deepen corporate social responsibility and team cohesion. Through diversified and ongoing health promotion measures, the Company integrates health concepts into daily work and life and builds a working environment that is safe, caring, and conducive to physical and mental balance.
