Samsung Electronics has officially appointed third-generation heir Lee Jae-yong as executive chairman, two months after he secured a pardon of his conviction for bribing a former president in a corruption scandal that toppled a previous South Korean government.

Lee's promotion is partially symbolic as he has helmed the Samsung group in his capacity as the electronics company's vice chairman since 2014, when his late father, former chairman Lee Kun-hee, suffered a heart attack.

Lee's legal troubles had been widely seen as a factor that prevented Samsung Electronics from quickly promoting him as chairman after the death of his father in 2020. The 54-year-old is now navigating one of his toughest stretches as the leader of one of the world's largest makers of computer memory chips and smartphones.

Russia-Ukraine war impact

The economic havoc unleashed by Russia's war on Ukraine and rising interest rates imposed by central banks to counter surging prices have slowed consumer spending on technology devices and deflated chip shipments.

Samsung and other semiconductor makers are also navigating new US restrictions on exports of advanced semiconductors and chipmaking equipment to China, in part of efforts to prevent American technology from advancing China's military.

Samsung Electronics' announcement that Lee is its new chairman came shortly after the company reported a 31 per cent drop in profit for the three months through September, its first year-to-year decline in quarterly profit in nearly three years.

The company said geopolitical uncertainties are likely to dampen demand at least through the first half of 2023. It said demand could recover later next year, driven by chips required for new data centres and computer products, Lee had already been out of prison on parole for a year when President Yoon Suk Yeol pardoned him in August for the corruption conviction, an act of leniency that underscored the tech company's huge influence in the nation.

Legal troubles

Lee was convicted in 2017 of bribing former President Park Geun-hye and her close confidante to win government support for a merger between two Samsung affiliates that tightened Lee's control over the corporate empire.

Park and the confidante were also convicted in the scandal and enraged South Koreans staged massive protests for months demanding an end to the shady ties between business and politics.

The demonstrations eventually led to Park's ouster from office. Lee still faces a separate trial on charges of stock price manipulation and auditing violations related to the 2015 merger.
