Amkor Technology, Inc. (Nasdaq: AMKR), a leading provider of semiconductor packaging and test services, announced today that James Kim will be stepping down as Executive Chairman of Amkor and retiring from the company effective October 31, 2024. Susan Kim, Amkor’s Executive Vice Chairman, will become Chairman of the Board at that time.

Mr. Kim founded Amkor in 1968 and has been a pioneer in the outsourced semiconductor assembly and test services industry during his more than 56 years of service to the company. In recognition of his extraordinary contributions, the Board will recognize Mr. Kim with the honorary title of Chairman Emeritus upon his retirement.

“After more than 50 years, I have decided that now is the appropriate time for me to retire,” said Mr. Kim. “Amkor is financially sound, and with our strong technology leadership in advanced packaging, a uniquely diversified global footprint, and partnerships with lead customers, we are well positioned for growth. I have full confidence in our president and chief executive officer, Giel Rutten, my daughter, Susan, as Chairman of the Board, and our other Board members to help lead the company to great success in the future.”

“I congratulate Mr. Kim on his remarkable achievements in this industry, and, on behalf of Amkor’s management team and the company’s employees, I thank him for his guidance and leadership,” said Giel Rutten, Amkor’s president and chief executive officer. “He had an entrepreneur’s vision of what Amkor could become, and he devoted immeasurable efforts to turn that vision into a strategic manufacturing partner for the world’s leading semiconductor companies, foundries and electronics OEMs. We welcome Susan Kim in her new role as Chairman of the Board. With this clear demonstration of continuing support from the Kim family, we will continue to follow Mr. Kim’s example of dedication and commitment as we work to extend Amkor’s position as a global advanced packaging leader.”
