SK Hynix Reaps 62 Trillion Won (42.7 Billion USD) from Kioxia Stake Exceeding Q2 Memory Operating Profit

Summary: SK Hynix recorded 62.166 trillion Korean won in Q2 non-operating revenue, exceeding its core memory operating profit of 60.5 trillion won for the same period. The windfall stems from partial stake sales and a massive valuation increase in Kioxia, the Japanese NAND manufacturer where SK Hynix originally invested around 4 trillion won in 2018. Following its December 2024 stock listing, Kioxia’s market value rose sharply from 860 billion yen to over 45 trillion yen, fueled by strong AI data center demand for high performance enterprise SSDs. SK Hynix secured 7 to 10 trillion won from recent share sales and holds convertible bonds valued at an additional 50 to 55 trillion won in gains, making it Kioxia’s effective second largest shareholder at a 14.17 percent potential stake. Industry analysts expect the Kioxia holding to remain a valuable asset alongside ongoing AI expansion, though the investment remains subject to memory market cycles and shifting tech spending.
