South Korea’s SK Hynix on Thursday posted a record quarterly profit as the Nvidia supplier saw strong sales of its advanced chips such as high bandwidth memory (HBM) ones used in generative AI chipsets. The world’s second-biggest memory chipmaker reported a 7 trillion won ($5.07 billion) operating profit for the July-September quarter versus a 1.8 trillion won loss a year earlier. That compared with a 6.8 trillion won average forecast by LSEG SmartEstimate, which is weighted toward analysts who are more consistently accurate.
