SK Hynix reported Q2 2026 revenue of KRW 79.32 trillion (~$56.5 billion)** , up 257% YoY, with operating profit of KRW 60.54 trillion, net profit of KRW 93.92 trillion, and a staggering **net margin of 118%** – the highest in its history. H1 2026 total revenue surpassed **KRW 100 trillion (~$71 billion) .

The explosive growth is driven by AI-driven memory pricing and a shift toward high-value products: HBM, server DRAM, and enterprise SSDs. HBM4 entered volume production in Q2, with HBM4E samples already delivered. Cash and equivalents rose to KRW 88 trillion, with net cash of KRW 69.4 trillion.

Samsung Electronics posted Q2 revenue of ~KRW 171 trillion (+129% YoY) and operating profit of ~KRW 89.4 trillion (+1810% YoY). Micron reported Q3 FY2026 revenue of $41.46 billion (+346% YoY), gross margin of 84.6%, and net income of $28.24 billion, with HBM4 samples already in customer testing.

All three memory giants are riding the AI supercycle, with HBM products becoming the key growth engine. SK Hynix plans to expand HBM4 capacity in H2, while its Cheongju M15X fab is already in production, and the Yongin campus is on track for 2027.

From ICgoodFind: 118% net margin – that's not a chip company, that's a money printer. The AI memory supercycle is rewriting the scoreboard, and HBM is the new oil.
