Business Overview

Amkor Technology, Inc. is the world's largest US-headquartered OSAT (outsourced semiconductor assembly and test) service provider. Our packaging and test services are designed to meet application and chip-specific requirements including: the required type of interconnect technology; size; thickness; and electrical, mechanical, and thermal performance. Some of the materials we use when providing packaging services contain tantalum, tin, tungsten, or gold (collectively, “Conflict Minerals”). Test services involve checking that a packaged die meets its design and performance specifications and do not involve the use of Conflict Minerals.

The supply chain that provides us with Conflict Minerals is divided into “upstream” and “downstream” entities. An upstream entity is an entity in our supply chain located between the mine of origin and the smelter or refiner and includes miners, local traders, exporters from the country of mineral origin, international concentrate traders, mineral processors, smelters, and refiners. A downstream entity is an entity in our supply chain located between the smelter or refiner and the retailer and includes metal traders and exchanges, component manufacturers, product manufacturers, original equipment manufacturers, and retailers.

Amkor is a downstream entity and is typically several tiers removed from the smelter or refiner and mineral origin. We have limited visibility beyond our direct suppliers to entities within our supply chain. Therefore, we rely principally on our direct suppliers to provide us with sourcing information.

Due Diligence Overview

We undertook due diligence on the source and chain of custody of the Conflict Minerals we use when providing packaging services using tools and relying on information provided by the Responsible Minerals Initiative (the “RMI”), an industry group that works to address Conflict Minerals issues within supply chains. One RMI tool we used as part of our due diligence was the Conflict Minerals Reporting Template (“CMRT”), which facilitates the collection of information on the source of Conflict Minerals. We also relied on information from the Responsible Minerals Assurance Process (“RMAP”), a voluntary initiative managed by the RMI, in which an independent third party validates the Conflict Minerals management procedures of a smelter or refiner to determine, with reasonable confidence, that the minerals it processes were sourced responsibly. If a smelter or refiner has committed to undergo an RMAP assessment, completed the relevant documents, and scheduled the RMAP assessment, they are designated by the RMI as “Active.” Upon completion of a successful audit, the smelter or refiner is designated by the RMI as “Conformant.”

Due Diligence Design

We designed our due diligence to conform to an internationally recognized due diligence framework, the Organisation for Economic Co-operation and Development (OECD), Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas, Third Edition, and related supplements on Tin, Tantalum and Tungsten and on Gold (collectively, the “OECD Framework”).

2

The OECD Framework provides a five-step outline for risk-based due diligence in the mineral supply chain. Our due diligence framework, which was designed to align with and incorporate the five-step outline from the OECD Framework, is summarized below.

Step 1 - Establish Strong Management Systems

•Adopt and revise, as needed, our Responsible Minerals Sourcing Policy, which states our goal to source Conflict Minerals responsibly and is located on the “About Us” tab of www.amkor.com, under “ESG.”

•Maintain an internal team to implement our Responsible Minerals Sourcing Policy, which includes members from the Procurement, Legal, and Quality Assurance teams, and reported program activities to Executive Management.

•Update processes and procedures, as appropriate, to meet the requirements of our Responsible Minerals Sourcing Policy.

•Enforce the requirement that our direct suppliers undertake due diligence to achieve a conformant supply chain.

•Maintain our record retention practice for records related to the sourcing of Conflict Minerals.

•Continue our existing grievance system where suppliers can submit questions or reports on ethical or legal issues, including issues relating to Conflict Minerals.

Step 2 - Identify and Assess Risks in the Supply Chain

•Conduct a survey of direct suppliers of Conflict Minerals in our supply chain using the CMRT to identify the smelters, refiners, and/or mines of origin of Conflict Minerals.

•Compare smelters, refiners, and/or mines of origin identified by our direct suppliers against the list of smelters, refiners, and mineral sourcing information that have received a “Conformant” designation by the RMAP.

•Perform reviews of select suppliers to evaluate the reasonableness of responses received and alignment with the OECD Framework.

3

Step 3 - Design and Implement a Strategy to Respond to Identified Risks

•Devise and adopt a risk management plan designed to mitigate the risk that our direct suppliers do not meet our expectations to achieve a conformant supply chain.

•Monitor risk management plan periodically by, among other methods, engaging directly with impacted suppliers, smelters, and refiners.

•Contact a portion of smelters and refiners within our supply chain to encourage them to maintain their participation in the RMAP or industry equivalent. Our outreach efforts include in-person training and meetings with select smelters and industry associations.

•Report information on the source and chain of custody of Conflict Minerals in our supply chain to Executive Management and the Audit Committee of the Company’s Board of Directors.

Step 4 - Carry Out Independent Third-party Audits of Smelter’s/Refiner’s Due Diligence Practices

•Maintain our membership in the RMI, an industry group that has implemented the RMAP to carry out independent third-party audits of a smelter’s or refiner’s Conflict Minerals management practices. As an RMI member, we rely on the results of the RMAP to provide smelter, refiner, and mineral sourcing information on the Conflict Minerals we used when providing packaging services.

Step 5 - Report Annually on Supply Chain Due Diligence

•Annually publish the results of our supply chain due diligence in a Specialized Report on Form SD and related Conflict Minerals Report, which are available on our website under the heading “Financial Information > SEC Filings” at https://ir.amkor.com.

Due Diligence Performed

In addition to the measures described above in the “Due Diligence Design” section of this Report, we undertook the following steps during the prior year to source Conflict Minerals responsibly:

•Conducted a supply chain survey of our direct suppliers of Conflict Minerals using the CMRT to identify the smelters, refiners, and/or mines of origin of Conflict Minerals.

•Continued engaging with our direct suppliers through periodic communications and evaluation of the smelter and refiner data provided to us.

•Followed established procedures designed to identify the smelters and refiners within our supply chain, including by evaluating the information received from our direct suppliers and comparing it with updated information published by the RMI.

4

•Contacted a portion of our smelters and refiners directly to encourage them to maintain their participation in the RMAP or industry equivalent.

•Continued our active involvement in the RMI and supported industry efforts to improve the monitoring and reporting of supply chain activities.

Due Diligence Results

The results of our due diligence indicate that the sources of Conflict Minerals are: (1) from recycled or scrap materials; (2) from within the Democratic Republic of the Congo or adjoining countries (the “Covered Countries”); or (3) from outside the Covered Countries. We received responses from all our direct suppliers subject to our supply chain survey for 2023. Collectively, their responses identified 218 smelters and refiners within their supply chains for the reporting year. 216 smelters and refiners had been designated as Conformant and 2 refiners had been designated as Active as of April 4, 2024.

The following tables list the population of smelters, refiners, and origin of Conflict Minerals within our supply chain for 2023. Our efforts to determine this population are described above under the caption “Due Diligence Performed.” The information presented is derived from information provided by our direct suppliers and the RMI.
