Section 1 - Conflict Minerals Disclosure

Item 1.01 Conflict Minerals Disclosure and Report

Conflict Minerals Disclosure

This Specialized Disclosure Report on Securities and Exchange Commission (“SEC”) Form SD (this “Form SD”) is filed pursuant to Section 13(p) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 13p-1 thereunder, which implements Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (Section 13(p) of the Exchange Act, Rule 13p-1 thereunder, and Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act collectively, the “Conflict Minerals Regulations”). Pursuant to the Conflict Minerals Regulations, Amkor Technology, Inc. (the “Company”) conducted a good faith Reasonable Country of Origin Inquiry in 2021 (the “RCOI”) on the sources of its Conflict Minerals (as defined in the Conflict Minerals Regulations) to determine whether the Conflict Minerals used when performing the Company’s semiconductor packaging services originated from the Democratic Republic of the Congo or an adjoining country (the “Covered Countries”) or are from recycled or scrap sources.

The Company conducted the RCOI with its direct suppliers using the Conflict Minerals Reporting Template (“CMRT”), a supply chain survey tool provided by the Responsible Minerals Initiative (“RMI”), an industry group that works to address Conflict Minerals issues within supply chains. The CMRT requests direct suppliers to identify the smelters, refiners, and countries of origin of the Conflict Minerals in their products. The Company relied primarily on responses received from its direct suppliers and information provided by the RMI to identify sources of the Conflict Minerals used by the Company.

Based on the responses to the Company’s RCOI, the Company knows or has reason to believe that a portion of the Conflict Minerals used by the Company originated or may have originated from the Covered Countries or may not be solely from recycled or scrap sources.

In accordance with the Conflict Minerals Regulations, the Company’s Conflict Minerals Report for the year ended December 31, 2021 (the “CMR”) is attached to this Form SD as Exhibit 1.01 and is incorporated into this Form SD by reference. Both reports are available on our website under the heading “Financial Information > SEC Filings” at https://ir.amkor.com. This Form SD and Exhibit 1.01 contain references to the Company’s website. The information on the Company’s website is not incorporated by reference into this Form SD or the CMR, nor are they deemed “filed” with the SEC pursuant to the Exchange Act or the Securities Act of 1933, as amended.

Business Overview

Amkor is one of the world’s leading providers of outsourced semiconductor packaging and test services. 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 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 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 the 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”).

6

Due Diligence Performed

The OECD Framework provides a five-step outline for risk-based due diligence in the mineral supply chain. Using the OECD Framework, we list below the actions taken to exercise due diligence on the source of Conflict Minerals we used when providing packaging services.

Step 1 - Establish Strong Management Systems

• Adopted and revised 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 “Social Responsibility.”

• Maintained 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.

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

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

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

• Continued our existing grievance system where suppliers can raise a question or make a report on ethical or legal issues, including issues relating to Conflict Minerals.

Step 2 - Identify and Assess Risks in the Supply Chain

• 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.

• Compared 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.

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

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

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

7

• Conducted training and communicated periodically with our direct suppliers to increase awareness of our goal to achieve a conformant supply chain and to reduce the risk of inaccurate information received from our suppliers.

• Contacted 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 included in person training and meetings with select smelters and industry associations.

• Reported information on the source and chain of custody of Conflict Minerals in our supply chain to Executive Management.

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

• Maintained 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 a member, we have relied 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

• Published the results of our supply chain due diligence in our Form SD for the year ended December 31, 2021 and this Report, which are available on our website under the heading “Financial Information > SEC Filings” at https://ir.amkor.com.

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 2021. Collectively, their responses identified 235 smelters and refiners within their supply chains as of December 31, 2021. As of December 31, 2021, the RMAP had designated 232 of those smelters and refiners as Conformant and three smelters as Active.

The following tables list the population of smelters, refiners, and origin of Conflict Minerals within our supply chain for 2021. 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.

As Amkor’s direct suppliers generally provide smelter and refiner information at the company level, the aggregate information reported by RMI does not necessarily imply that minerals originating from this country are incorporated in the materials purchased by Amkor.

Due Diligence Improvements

We plan to undertake the following steps in 2022 to build on our efforts to source Conflict Minerals responsibly:

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

• Maintain our efforts to identify the smelters and refiners within our supply chain by evaluating the information received from our direct suppliers and comparing it with updated information published by the RMI.

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

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