Why is SK Hynix stock sliding today?

SK Hynix shares dropped 7.2% to 296,000 won on Thursday due to a broader sell-off in South Korean semiconductor stocks. The decline was driven by concerns over U.S. AI regulations and delayed chip equipment export licenses for China. Weak earnings from Arm and Qualcomm also contributed to the downturn. Investors sold off AI-exposed chipmakers, including SK Hynix, on fears of reduced demand for high-bandwidth memory.

US export restrictions on China threaten SK Hynix's plans to build $45 billion worth of chip plants in New York

The US Commerce Department is delaying export licenses for SK Hynix to ship chipmaking equipment to its Dalian, China plant, complicating its $45B plan to build memory plants in New York. SK Hynix argues increased Dalian production would fund the US project, but Commerce opposes licensing equipment for Chinese plant expansion. Solidigm, SK Hynix's US subsidiary, is negotiating licenses and exploring alternative funding, including a potential IPO.
