SK Hynix reported third-quarter revenue of about $78.8 billion, up 327.9% year over year, beating analyst estimates of roughly $74.07 billion. Operating profit surged 632.1% to approximately $62.76 billion, also above the expected $57.78 billion, according to CNBC.
Compared with the previous quarter, revenue climbed 31.9% and operating profit rose 37.6%. The South Korean chipmaker posted record quarterly revenue and operating profit, with sales exceeding 100 trillion won for the first time. The results underscore how high-bandwidth memory (HBM) has become the bottleneck of the AI boom.
