Management Guideline on Hazardous Substances and Sustainable Raw Materials Edition: 2026-07 I. General Provisions 1. Purpose The guideline applies to the manufacturing facilities of all ASE Holdings’ (ASEH) subsidiaries worldwide. Each subsidiary is required to establish a comprehensive management systems for hazardous substance and raw material management at their respective manufacturing facilities. This will encompass a systematic process of identification, evaluation, control and disclosure of all substances used in products, raw materials, and the manufacturing processes to ensure compliance with international trends/laws/standards and customer/stakeholder requirements. At ASEH, we are deeply committed to sustainability development and the mitigation of negative impacts on the environment and human health. To that end, we continue to focus on identifying alternative substances and phasing out hazardous substances through internal mechanisms for risk assessment, alternative or sustainable materials, and continuous improvement as well as external partnerships with industry associations through research and funding. 2. Scope The guideline applies to the manufacturing facilities of all ASE Holdings’ (ASEH) subsidiaries worldwide, and cover substances and materials (including direct materials, indirect materials, and chemicals) intended for use in the manufacturing process, with the exception of prototypes or those subject to special conditions (including but not limited to military specifications) . As the type of substances and materials used vary across each manufacturing facility, detailed records of controlled substances and materials should be maintained in the internal management regulations or the standard operating procedures (SOP) of each facility. II. Terms and Definitions 1. Substance Chemical elements, compounds, or polymers. 2. Material Direct materials, indirect materials, and chemicals. 3. Hazardous Substance Products, raw materials, processes or services containing any substance that poses potential risks or adverse impact on health, the environment or product compliance; and those substances that are subject to restrictions, prohibition and regulatory control according to international regulations, industry standards or customer requirements. 4. Prohibited Substance For any substance that has been banned by international bodies or stakeholder groups, third-party testing should confirm that no traces of the substance is detected in products or manufacturing processes. 5. Restricted Substance For any substance that has been restricted for use by international bodies or stakeholder groups, third-party testing should confirm that the amount used is within the permissible concentration limit for products or manufacturing processes. 6. Controlled Substance Any substance on the list requiring monitoring and control, or being phased out in accordance with the regulations and standards of international bodies or stakeholder groups. 7. Sustainable Raw Material Sustainable raw material that reduce environmental impact, promote circularity and comply with social, environmental and regulatory requirements throughout their life cycle (including extraction, manufacturing, use and end-of-life disposal) . Their characteristics may include but are not limited to the following: (1) minimal environmental and ecological impact. (2) can be recycled, recyclable or reusable, and biodegradable, ensuring resource efficiency and circularity. (3) sustainably and responsibly sourced to prevent deforestation, damage to biodiversity-sensitive areas, and the use of conflict minerals. (4) human-and eco-friendly, containing zero or reduced amounts of hazardous substances. III. Substance Management: Guideline Requirements 1. Establish a robust SOP. All manufacturing sites must establish SOPs for substance identification including but not limited to hazardous, prohibited, restricted, and c
