SK hynix reported second quarter 2026 revenue of 79.3187 trillion won (approximately $55.22 billion), operating profit of 60.5426 trillion won (approximately $42.15 billion), and net profit of 93.9226 trillion won (approximately $65.39 billion), marking an all-time high quarterly performance. Revenue rose 257% year-over-year and operating profit rose 557%, up from 22.232 trillion won (approximately $15.48 billion) in revenue and 9.2129 trillion won (approximately $6.41 billion) in operating profit in the second quarter of 2025.
The company said high-performance products for AI servers led price increases as demand from expanding AI infrastructure investments continued to grow. Cumulative first-half revenue crossed 100 trillion won (approximately $69.61 billion) for the first time in company history. Both DRAM and NAND flash memory prices rose significantly quarter-over-quarter, and SK hynix said it achieved top-tier profitability by expanding sales of high-value-added products, including HBM, DRAM for AI servers, and eSSD.
Cash and cash equivalents reached 88 trillion won (approximately $61.26 billion) at the end of the quarter, an increase of 33.6 trillion won (approximately $23.39 billion) from the prior quarter. Total debt decreased by 0.7 trillion won (approximately $487 million) to 18.6 trillion won (approximately $12.95 billion), expanding the company’s net cash position to 69.4 trillion won (approximately $48.31 billion).
SK hynix said it has finalized long-term agreements with around 10 customers, including key strategic partners, to secure mid-to-long-term supply stability, with further discussions continuing with major industry clients. The company began mass shipments of HBM4 during the quarter and plans to ramp up production in the second half of the year. SK hynix said HBM4 has demonstrated its differentiated technological edge by meeting customer-required operating speeds while delivering industry-leading power efficiency and cost competitiveness, and it completed HBM4E sample shipments during the first half.
Sales of SOCAMM2 grew significantly during the quarter, and shipments of products based on 10-nanometer-class sixth-generation process technology began in earnest. In NAND, SK hynix said 321-layer products already represent the largest share of total production and that it plans to expand that share to approximately 50% of domestic production capacity by the end of the year.
SK hynix said it is accelerating the mass production schedule for its M15X facility and investing to rapidly expand production capacity following the opening of the Yongin Phase 1 cleanroom, expected in early 2027. The company said mid-to-long-term investment plans, including the previously announced P&T7 advanced packaging facility and M17 NAND production base, will be executed in phases based on customer demand and investment efficiency, while it maintains capital expenditure discipline.
