SK hynix reported record-breaking financial results for fiscal year 2025, driven by strong AI memory demand and the rapid expansion of high value-added products such as HBM.
The company posted FY2025 revenue of KRW 97.15 trillion, operating profit of KRW 47.21 trillion, and net profit of KRW 42.95 trillion, marking the highest annual performance in its history. Revenue rose by more than KRW 30 trillion year on year, while operating profit nearly doubled, supported by a sharp improvement in margins to 49%.
Momentum accelerated in the fourth quarter, with revenue rising 34% quarter on quarter to KRW 32.83 trillion and operating profit surging 68% to KRW 19.17 trillion. Operating margin reached 58%, reflecting strong pricing and product mix, particularly in HBM and server memory.
HBM revenue more than doubled year on year, while SK hynix strengthened its leadership in advanced DRAM with mass production of the 1cnm process and the launch of high-capacity 256GB DDR5 server modules. In NAND, the company completed development of 321-layer QLC products and achieved record annual revenue, supported by strong eSSD demand in the second half.
Looking ahead, SK hynix expects sustained growth as AI workloads expand from training to inference, increasing demand not only for HBM but also for server DRAM and NAND. The company plans to maintain leadership in HBM4, expand custom HBM offerings, and scale production capacity through new fabs and advanced packaging facilities in Korea and the US.
Reflecting its strong cash generation, SK hynix announced enhanced shareholder returns, including an additional KRW 1 trillion dividend and the cancellation of 15.3 million treasury shares. Management emphasized a continued focus on balancing long-term investment, financial stability, and shareholder value while positioning the company as a core infrastructure partner in the AI era.
