Conflict Minerals Report of Amkor Technology, Inc.

This Conflict Minerals Report for the year ended December 31, 2023 (this “Report”) of Amkor Technology, Inc. (the “Company,” “Amkor,” “we,” or “us”) contains forward-looking statements within the meaning of the federal securities laws. You are cautioned not to place undue reliance on forward-looking statements, which are often characterized by terminology such as “may,” “will,” “should,” “expects,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “potential,” “continue,” or “intend,” by the negative of these terms or other comparable terminology, or by discussions of strategy, plans, or intentions. All forward-looking statements in this Report are made based on our current expectations, forecasts, estimates, and assumptions. Because such statements include risks, uncertainties, assumptions, and other factors, actual results may differ materially from those anticipated in such forward-looking statements, including, but not limited to, 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, our ability to identify and mitigate related risks in our supply chain, and other important risk factors discussed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 (the “Form 10-K”) and from time to time in the Company’s other reports filed with or furnished to the Securities and Exchange Commission (“SEC”). You should carefully consider the trends, risks, and uncertainties described in this Report, the Form 10-K, and other reports filed with or furnished to the SEC before making any investment decision with respect to our securities. If any of these trends, risks, or uncertainties continues or occurs, our business, financial condition, or operating results could be materially adversely affected, the trading prices of our securities could decline, and you could lose part or all of your investment. All forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by this cautionary statement. We undertake no obligation to review or update any forward-looking statements to reflect events or circumstances occurring after the date of this Report except as may be required by applicable law.

This Report was prepared in accordance with 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”).

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

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.

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:

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.
