Key Human Rights Issues

The Company places importance on and manages key human rights issues, including anti-discrimination, anti-harassment, freedom of association, prohibition of child labor, protection of young workers, and prohibition of forced labor. These requirements apply to Board members and all employees. The Chairman serves as the highest level responsible for the formulation of the human rights policy and related issues, while the Global Human Resources Division and the management departments at each operating site are responsible for oversight and implementation to ensure consistency between corporate governance and operational practices.

We have established comprehensive policies and management mechanisms to ensure that all personnel enjoy equal opportunities at every stage of recruitment, hiring, training, promotion, and compensation, and to provide a safe, respectful, non-discriminatory, and harassment-free working environment. At the same time, the Company respects employees' legal rights to organize unions and participate in collective bargaining, and has established effective communication and grievance channels to safeguard the lawful rights and interests of both labor and management.

In labor practices, the Company strictly prohibits the employment of child labor and any form of forced or coercive labor, and manages the work content, working hours, and health protection measures for young workers in accordance with the law to ensure their rights and safety. In 2025, the Company did not experience any human rights violations involving discrimination, child labor, or forced labor. To continue maintaining a sound human rights environment, the Company will keep improving relevant training and supporting management measures.

To implement its human rights policies and ensure that employees, workers, and suppliers fully understand them, the Company regularly reviews the relevant policies and announces them to relevant personnel, while also promoting awareness through public events, training courses, and seminars. In addition, procedure documents related to the human rights policy have been translated into Simplified Chinese and English for reference by overseas employees and suppliers, so as to ensure that the policy is implemented across operating sites and throughout the value chain.

The above policies and measures also extend to supply chain management. Through measures such as signed commitment letters and audits, the Company requires business partners to jointly comply with human rights standards in order to implement responsible business conduct and reduce human rights risks.

Human Rights Training and Awareness Promotion

To ensure the full implementation of human rights principles, we have incorporated human rights-related courses into new employee training across all sites, ensuring that 100% of new personnel complete the training and develop proper human rights and ethical awareness from the time of onboarding. At the same time, for incumbent employees, the Company regularly provides annual human rights-related education and training courses to continuously strengthen employees' awareness of human rights issues, labor rights, and responsible business conduct, as well as their practical capabilities.

Grievance Channels

To uphold its philosophy of transparent communication, the Company encourages all internal employees to report issues through grievance channels and accepts anonymous or unnamed reports. The Company has established an employee opinion mailbox and a dedicated email mailbox (0800employee@sunon.com) as channels for employee grievances. For cases involving violations of Company rules, the Global Human Resources Division serves as the primary receiving unit and, depending on the nature of the case, establishes a cross-departmental investigation team responsible for investigating the case, reviewing grievance content, and formulating improvement measures. At the same time, the Company compiles employee grievance cases and handling results each year and reports them to the Board, while the Internal Audit Office is responsible for overseeing the investigation and handling procedures for grievance cases.

External workers and business partners may submit reports or grievances through the hotline (+886-7-8135888 #1195), the email mailbox (0800employee@sunon.com), or the relevant responsible personnel of the primary corresponding unit, in order to ensure smooth communication and timely handling of human rights-related matters for all workers and suppliers.

Sunon fully implements energy saving, environmental protection, resource reuse, cost reduction, and reduction of carbon dioxide and other greenhouse gas emissions. Sunon will base its actions on ISO 14001 standards to effectively reduce industrial waste and promote resource recycling, while also controlling the generation and emission of waste gas, noise, and waste to mitigate the impact on the ecological environment.

To strengthen the management and transparency of greenhouse gas emissions, we have introduced and obtained certification for the ISO 14064-1 international greenhouse gas inventory standard, establishing a systematic emission inventory and internal verification process to accurately grasp the current emission situation. In the future, we will continue to plan and promote concrete and feasible carbon reduction solutions based on the inventory results, moving towards the long-term goals of low-carbon operations and net-zero emissions.

Sunon, in order to ensure that products fully comply with the EU RoHS Directive (2011/65/EU) and the REACH (Registration, Evaluation and Authorization of Chemicals System-Regulation (EC) No 1907/2006) new chemical policy's green environmental protection regulations, has established a dedicated green supply chain system for the Sunon Group. It has fully implemented a green procurement process, requiring material suppliers not to use or contain prohibited controlled substances (lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium (Cr6+), polybrominated biphenyls (PBBs), polybrominated diphenyl ethers (PBDEs)) in production and products, and to provide relevant certification documents proving the non-use of harmful substances for review. Sunon strictly controls this process, demonstrating the environmental commitment guaranteed by Sunon's products. Sunon is very concerned about the social and environmental issues arising from the raw materials and processes used in manufacturing products. The Democratic Republic of the Congo has rich mineral resources, including gold (Au), tantalum (Ta), tin (Sn), and tungsten (W) (collectively referred to as 3TG), which are essential metals used in electronic devices. However, in these areas, the mining development process has led to many incidents of violence funded by the illegal trade of mineral products for profit, resulting in massacres and rampant human rights violations in conflict-affected areas. As a global citizen, Sunon respects international human rights and commits to not accepting metals sourced from conflict zones to ensure a safe working environment in the supply chain, where workers are respected and treated with dignity. We expect our suppliers, based on their responsibility to the environment and society, to avoid using conflict minerals, conduct reasonable investigations of their supply chains, and ensure that the materials provided to Sunon do not contain "conflict minerals," fulfilling their corporate citizenship responsibilities.
