Samsung Electronics, SK Hynix DRAM operating margin nears 80 percent as memory boom holds firm

Samsung Electronics and SK Hynix are expected to post record quarterly results as their combined second-quarter operating profit nears 150 trillion won. Samsung reported preliminary operating profit of 89.4 trillion won, while SK Hynix is seen earning in the 60 trillion won range. Analysts estimate most of Samsung’s profit came from memory despite losses in non-memory units and large bonus provisions. Brokers expect memory supply tightness, HBM demand and AI-driven growth to support results.
