AMKOR TECHNOLOGY Business Summary

Amkor Technology, Inc. (AMKR) is a premier provider of outsourced semiconductor assembly and test (OSAT) services, generating revenue through high-volume packaging and testing of integrated circuits for the communications, automotive, and computing industries. The company’s revenue model is driven by service fees across two primary segments: Advanced Products, which includes flip-chip, wafer-level packaging, and System-in-Package (SiP) technologies (representing approximately 83% of net sales), and Mainstream Products, focused on traditional wirebond interconnects. Amkor is currently executing a $2.5–$3.0 billion capital expenditure strategy for 2026 to scale high-density fan-out (HDFO) capacity and complete its advanced packaging facility in Arizona to support AI and high-performance computing demand. As the world’s second-largest OSAT provider by market share, Amkor maintains a critical position in the global supply chain, competing directly with industry leader ASE Technology Holding Co., Ltd. (ASEH), as well as JCET Group and Powertech Technology Inc. (PTI). Founded in 1968 by James J. Kim, who now serves as Chairman Emeritus, Amkor is led by President and CEO Kevin Engel, who took the helm in January 2026 after two decades in executive roles, including Chief Operating Officer. The leadership team includes Executive Vice President and CFO Megan Faust and Chairman of the Board Susan Y. Kim, who succeeded the founder in late 2024. The company’s governance is supported by a board of directors featuring Lead Independent Director Winston J. Churchill and John Liu, a veteran finance executive appointed in December 2024. Amkor is a publicly traded entity with significant institutional ownership from major investors including The Vanguard Group, BlackRock, and Dimensional Fund Advisors, reinforcing its standing as the largest U.S.-headquartered provider in the semiconductor packaging sector.
