South Korea’s SK Hynix posted on Thursday a record quarterly profit, driven by strong demand for advanced chips used in generative artificial intelligence chipsets and as some customers stockpiled semiconductors ahead of potential U.S. tariffs. The Nvidia supplier reported a 9.2 trillion won ($6.69 billion) operating profit for the April-June period versus 5.5 trillion won a year earlier. That compared with a 9.0 trillion won average forecast by LSEG SmartEstimate, which is weighted toward analysts who are more consistently accurate.
