Koo Bon-neung is a South Korean businessman tied to the LG and Heesung groups. He began at LG in 1976 as a manager in the company’s Chicago branch. Over time, he held posts in overseas operations and then moved into senior roles at Goldstar, Heesung Metals, and Sangnong Enterprise, now Heesung Electronics. In 1996, when Heesung Group split from LG, he became the head of the business and built his profile through electronics manufacturing.
His wealth is linked to electronics, especially through Heesung Electronics. The company makes display components used in TVs, computers, tablets, and smartphones. That puts the business inside a wide range of consumer devices rather than one single product line. Outside the factory floor, he also had a public role in sports. He served as commissioner of the Korea Baseball Organization from 2011 to 2017 and was previously an advisor to the LG Twins.
How Koo Bon-neung built his fortune
Koo Bon-neung’s money comes from electronics. He runs Heesung Electronics, a company that makes display parts for TVs, computers, tablets, and smartphones. Those components place the business in the supply chain for several big device categories. His career started at LG in 1976, and he later took on leadership jobs across related companies. By 1996, after Heesung Group split off from LG, he was leading that business.
His path shows a long move through management rather than a startup story. He worked in LG’s Chicago branch and overseas headquarters, then became director of Goldstar in 1987. After that, he served as auditor of Heesung Metals in 1988, vice president of Sangnong Enterprise in 1990, and president of Heesung Metals in 1992. By 2018, he owned 3.45% of LG Corporation stock, adding another clear tie to the wider LG business network.
What Forbes says about his wealth
Forbes has tracked Koo Bon-neung’s fortune for years. It put him at $1.3 billion in 2015 and again at $1.3 billion in 2018. The estimate then moved to $1 billion in 2019, rose to $1.2 billion in 2021, slipped to $1.1 billion in 2022, and returned to $1 billion in 2023. Those shifts show that billionaire estimates can move up and down over time.
More recently, Forbes estimated him at $1.2 billion in 2024, then $2.6 billion on the 2026 billionaires list. Forbes’ real-time tracker later showed $3.4 billion in Oct 2026, and the current figure is $3.4 billion as of October 20, 2026. Forbes places him in technology, while describing the source behind that wealth as electronics. That lines up with Heesung Electronics and its display-component business.
