❯ SK hynix tops 100 trillion won in quarterly revenue as HBM4 ramps

Record sales and operating profitSK hynix’s October 28 results show third-quarter revenue of 104.62 trillion won, up 328%, and operating profit of 83.33 trillion won, up 632%, for an operating margin near 80%. Net profit was 39.78 trillion won. Reporting in won avoids differences between media outlets’ dollar conversions.

More than HBM is growingAI servers need high-bandwidth memory beside accelerators, conventional server DRAM and enterprise SSDs for storage. SK hynix says HBM4 shipments accelerated, server DDR5 sales rose sharply and 321-layer TLC enterprise SSD sales expanded. A richer product mix and higher prices for major memory products supported revenue and profit.

HBM4 is nextThe company plans to maximize M15X capacity by year-end and expects HBM4 to exceed HBM3E in shipments and revenue in the fourth quarter. It also aims to raise 321-layer technology above half of domestic NAND capacity to increase high-performance enterprise SSD supply. These are forward operating targets, not completed sales results.

Cash supports the next expansionQuarter-end cash and equivalents reached 114.5 trillion won, with debt of 15.8 trillion won and net cash of 98.7 trillion won. That supports investment and shareholder distributions. Continued growth will depend on capacity delivery, product transitions and customer consumption. The immediate development is that AI demand is appearing across several memory businesses’ earnings.

▮ SIGNALAI memory growth is spreading from HBM into server DRAM and enterprise storage, with product upgrades amplifying the conversion of revenue into profit.
