Samsung Electronics co-CEO Han Jong-Hee has died at the age of 63 from cardiac arrest, the South Korean tech giant confirmed on Tuesday.

Han, who joined Samsung in 1988, dedicated over 37 years to the company, playing a pivotal role in establishing its TV business as a global leader. He was appointed vice chairman and co-CEO in 2022, overseeing the company’s consumer electronics and mobile devices divisions, while co-CEO Jun Young-Hyun managed its semiconductor business.

In an internal message, Samsung paid tribute to Han, stating, "He contributed immensely to the company’s growth amid a challenging business environment." The company extended its condolences to his family and loved ones. No announcement has been made regarding his successor.

Han’s passing comes at a critical time for Samsung, which has been facing increasing competition in the semiconductor industry. The company lags behind Taiwan Semiconductor Manufacturing Company (TSMC) in producing advanced chips and securing key customers.

Just last week, Han chaired Samsung’s annual investor meeting, where he apologized for the company’s stock performance and cautioned about a tough 2025 due to economic uncertainties. He also outlined plans for "meaningful mergers and acquisitions" to drive growth. "There are challenges in semiconductor M&As due to regulatory and geopolitical factors, but we are determined to achieve tangible results this year," he stated.

Han, an alumnus of Inha University with a degree in electrical engineering, was instrumental in launching Samsung’s LED TVs and other groundbreaking innovations. Samsung described him as "central" to the company’s technological leadership, leaving behind a legacy of innovation and strategic growth.
