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 2025 (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, 2025 (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 the Company’s 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.

Item 1.02 Exhibit

Information concerning Conflict Minerals required by the Conflict Minerals Regulations is included in Exhibit 1.01 to this Form SD.
