SK hynix stock gained 1.20 percent to KRW 1,862,000 on the Korea Exchange on September 23, 2026. The move followed a second-quarter performance in which revenue reached KRW 79.3 trillion, up 257 percent year over year, according to Yahoo Finance.
Profit growth outpaced revenue
The earnings mix was even more striking than the sales figure. SK hynix posted KRW 60.5 trillion in second-quarter operating profit, a 557 percent increase from KRW 9.21 trillion in the same quarter of 2025.
Operating margin reached 76 percent, compared with 41 percent a year earlier. The result shows why memory pricing and product mix matter more than revenue growth alone for the companys earnings power.
AI demand drives memory pricing
Yahoo Finance reported that second-quarter revenue increased 51 percent from the prior quarter, while operating profit rose 61 percent sequentially. Management linked the gains to AI-led demand, higher average selling prices and tight supply across memory products.
DRAM and NAND pricing therefore remain the key variables for the next earnings cycle. A 76 percent operating margin gives SK hynix considerable earnings leverage, but it also raises the importance of sustained pricing and supply discipline.
KRW 1,862,000 marks the latest level
SK hynix stock stood at KRW 1,862,000 on KRX on September 23, 2026, up 1.20 percent for the session. The market reaction aligns with the companys combination of 257 percent revenue growth and 557 percent operating profit growth in Q2 2026.
