August 14 is shaping up as a pivotal day for South Korea's corporate sector, bringing together nuclear energy diplomacy, AI manufacturing talks, a closely watched chaebol divorce case and potential shareholder return announcements. Bill Gates is due in South Korea to discuss small modular reactors, or SMRs (small-scale nuclear reactors), with Prime Minister Han Sung-sook, National Assembly Speaker Cho Jung-sik and business leaders including SK Group and HD Hyundai, as TerraPower pushes ahead with its Natrium project in the United States and South Korean suppliers expand their roles. The visit comes as Seoul steps up support for SMR development to meet rising electricity demand tied to AI data centers. On the same day, the appeal deadline arrives in the divorce dispute between SK Group Chairman Chey Tae-won and Art Center Nabi Director Noh So-young after a Seoul High Court ruling ordered Chey to pay ₩944 billion in property division and ₩2 billion in alimony. Market attention is also on LG Group Chairman Koo Kwang-mo's expected meeting with Nvidia CEO Jensen Huang in California to discuss "physical AI," or the use of AI in factories and robotics. Investors are additionally watching whether Samsung Electronics and SK Hynix unveil new shareholder return measures as they file semi-annual reports that will also disclose high-level compensation data.
