Samsung Electronics Chief Jay Y. Lee is facing a potential 5-year prison sentence and a 500 million KRW fine, equivalent to $375,000, as South Korean prosecutors presented their case in an appeals court on Monday. This development comes 10 months after Lee and 13 former Samsung executives were originally acquitted of manipulating stock prices and committing accounting fraud in connection with the merger of Samsung subsidiaries in 2015.

The merger, which increased Lee's control over the tech giant, has been at the center of the controversy. Prosecutors claim that Lee and the other executives engaged in unlawful activities to solidify his control over the company. The appeals case is expected to deliver a decision between January and February 2025, according to local media outlets.

The hearing holds significant implications for Samsung, which is currently navigating slowing profits as the leading maker of memory chips. Moreover, the outcome of the case will have far-reaching consequences for the country's efforts to reform its corporate structure, affecting not only Samsung but also the broader technology ecosystem in Korea, including startups.

Prosecutors emphasized the importance of the case, stating that "the defendant damaged the capital market's foundation for the group's succession… The ruling in this case will serve as a reference point for restructuring chaebol companies, [which is a large, family-controlled business conglomerate in South Korea], and accounting in the future." They warned that if the defendants are granted leniency, the merger would be carried out in a manner that prioritizes their interests by resorting to unlawful and expedient means without hesitation.

This is not the first time Lee has faced legal scrutiny. In November 2023, prosecutors called for Lee to be sentenced to five years in jail and fined 500 million KRW over charges of violating the Capital Market Act related to the same $8 billion merger of Samsung affiliates in 2015. Lee refuted the misconduct allegations during the November 2023 hearing, asserting that the merger process was within the scope of standard operational procedures for the company.

The legal battle dates back to September 2020, when Lee, then the vice-chair of Samsung Electronics, along with other former Samsung executives were indicted for advocating the merging of Cheil Industries, Samsung's textile affiliate, with Samsung C&T, its construction unit, to take over the tech giant's management controls in 2015. They were also accused of inflating the stock price of Cheil and Samsung C&T and fraudulent accounting at Samsung Biologics, in which Cheil held a significant stake, as part of the same case.

The prosecution claimed that Samsung had a strategy to merge that helped Lee solidify his control and take over management rights. As the appeals court deliberates on the case, the tech industry will be watching closely for a decision that could have significant implications for corporate governance and accountability in South Korea.
