1. Life and Education
Choi Tae-won was born in Seoul in 1960, graduated from Kyunggi High School, and entered Korea University's Business Administration program. He later earned an MBA from the University of Chicago Graduate School of Business. He began his management training by joining SK Chemicals (then Sunkyong Fibers) in 1987, and became chairman of SK Group at the age of 38 in 1998 following his father's sudden death.
2. Growth and Innovation of SK Group
Immediately after taking office, Chairman Choi fostered the information and communications business centered on SK Telecom amid the foreign exchange crisis, and in 2012 acquired Hynix Semiconductor (now SK hynix), propelling it to become a key player in the global semiconductor market. He also expanded the oil refining, chemical, and battery businesses through SK Innovation, and entered the bio and pharmaceutical sectors via SK Biopharm and SK Bioscience. Recently, he has focused on hydrogen and energy solution businesses through SK E&S, and SK Telecom's AI, data center, and cloud businesses as future growth engines.
3. Management Philosophy: 'Deep Change' and 'Social Value'
Choi Tae-won has proposed 'Deep Change' as the group's core management policy, emphasizing fundamental innovation of existing businesses and discovery of new ventures. In particular, he introduced a unique management system that measures and manages 'Social Value' on par with financial performance. Since 2018, SK Group has published a 'Social Value Measurement Report,' quantifying environmental (E), social (S), and governance (G) performance. This is the first such attempt by a domestic company and is evaluated as a leading model for ESG management.
4. Major Business Portfolio
- Semiconductors: SK hynix ranks second globally in the DRAM and NAND flash markets and leads the AI semiconductor (HBM) market.
- Energy and Batteries: SK Innovation has grown its electric vehicle battery business to a global top-five level, while SK E&S is pursuing liquefied natural gas (LNG) and hydrogen businesses.
- Information and Communications and AI: SK Telecom has developed the AI semiconductor 'Sapeon' and is expanding new businesses such as AI data centers, cloud, and metaverse (ifland).
- Bio and Pharmaceuticals: SK Biopharm launched the epilepsy drug 'Cenobamate' in the U.S. market, and SK Bioscience focuses on contract manufacturing of COVID-19 vaccines and developing influenza vaccines.
5. Personal Life and Controversies
As of 2024, Choi Tae-won is in divorce proceedings with Roh So-young, director of the Art Center Nabi, and a Supreme Court ruling finalized a property division of approximately 1.38 trillion won, drawing social attention. He was also indicted and detained in 2003 on charges of fraudulent bond issuance, receiving a special pardon and restoration of rights in 2008. Despite these controversies, his management skills and investments in future industries continue to earn him high regard as a businessman.
Latest Trends
As of 2024–2025, Chairman Choi is focusing on SK Group's 'rebalancing' (business restructuring). In response to SK On's (battery) continued losses and the EV chasm (temporary demand slowdown), he has initiated battery business restructuring and profitability improvement. Additionally, SK hynix is exclusively supplying HBM3E (high-bandwidth memory) to Nvidia, maintaining a super-gap in the AI semiconductor market. In January 2025, Chairman Choi announced a vision combining 'AI and Energy' at CES 2025, declaring the transformation of SK Group into a 'global AI and energy solution company.' In particular, he emphasized the 'AI Total Solution' strategy of integrating power solutions and semiconductors for AI data centers through collaboration among SK Telecom, SK hynix, and SK E&S. Meanwhile, the property division issue related to the divorce lawsuit remains a topic of interest in the business community and among the public.
