Conflict Minerals Report of Amkor Technology, Inc.

All information contained in this Conflict Minerals Report (the “Report”), other than statements of historical fact, constitute forward-looking statements within the meaning of federal securities laws. These forward-looking statements involve a number of risks, uncertainties, assumptions and other factors including, among other things, our customers’ requirements to use certain suppliers, our suppliers’ responsiveness and cooperation with our due diligence efforts, our ability to implement improvements in our conflict minerals program, changes to the sourcing status of smelters and refiners in our supply chain, and our ability to identify and mitigate related risks in our supply chain. For a more complete discussion of these and other risk factors, see our other filings with the Securities and Exchange Commission (“SEC”), including our Annual Report on Form 10-K for the year ended December 31, 2019. We undertake no obligation to review or update any forward-looking statements to reflect events or circumstances occurring after filing this Report with the SEC.

This Conflict Minerals Report (CMR) of Amkor Technology, Inc. (“Amkor”) for calendar year 2019 was prepared in accordance with Rule 13p-1 under the Securities Exchange Act of 1934.

Business Overview

Amkor is one of the world’s leading providers of outsourced semiconductor packaging and test services. Packaging is the processing of bare die, a small block of semiconducting material on which a functional circuit is fabricated, to facilitate electrical connections, heat dissipation and protection of the die. Some of the materials we use when providing packaging services contain tantalum, tin, tungsten, or gold (“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.

1

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 (RMI), an industry group that works to address Conflict Minerals issues within supply chains. One RMI tool we used 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. 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”).

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”.

2

• 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.

• Conducted training and communicated periodically with our direct suppliers to increase awareness of our goal to achieve a conflict free 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.

3

• 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/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/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 within our 2019 Form SD and Conflict Minerals Report, which is located on the “Investors” tab of www.amkor.com under “Financial Information, SEC Filings”.

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 2019. Collectively, their responses listed 224 smelters and refiners within their supply chains as of December 31, 2019, all of which have been designated as Conformant under the RMAP as of December 31, 2019.

The following tables list the population of smelters, refiners, and origin of Conflict Minerals within our supply chain for 2019. 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.

Due Diligence Improvements

We plan to undertake the following steps in 2020 to build on our efforts to source Conflict Minerals responsibly:

• Continue our engagement with our direct suppliers with periodic communications, training and evaluation of smelter and refiner data provided.

• 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.
