SK Innovation has established a co-CEO structure with Jang Yong-ho and Choo Hyeong-wook. Jang is expected to focus on reshaping the business portfolio and improving the financial structure, while Choo will concentrate on strengthening the competitiveness of core businesses such as refining, chemicals, and batteries and on developing new businesses.
SK Innovation said in a filing that its board met on the afternoon of the 24th and approved an agenda item to appoint Jang Yong-ho, the overall president, as CEO. Earlier that morning, at the regular shareholders meeting, Jang was appointed as an inside director.
With this board approval, SK Innovation will operate under a co-CEO system in which Jang and Choo Hyeong-wook divide their roles.
Born in 1964, Jang graduated from the economics department at Seoul National University and joined Yukong, the predecessor of SK Innovation. Jang led the group's energy and chemical fields for a long time and also served as CEO of SK Materials and SK Siltron. Since 2024, Jang has concurrently served as CEO of SK Inc.
Born in 1974, Choo received a master's degree in business administration from Sungkyunkwan University. After taking office in 2021 as CEO and president of SK E&S, Choo pursued a growth strategy based on four core businesses—low-carbon LNG, renewable energy, energy solutions, and hydrogen—and was appointed CEO of SK Innovation last year.
An SK Innovation official said, "Jang is a leader who has proven managerial capabilities across various areas, including energy, semiconductors, and materials," adding, "By dividing roles with Choo, they will work to strengthen the competitiveness of core businesses and improve the corporate structure."
