Nvidia supplier SK Hynix achieves record third quarter profit and meets expectations

Strong Financial Performance in Q3 2025

SK Hynix, the major Nvidia supplier, reported its highest-ever third-quarter profit, reflecting surging demand for high-bandwidth memory (HBM) widely used in Chatgpt and other artificial intelligence applications. The South Korean chipmaker's revenue and operating profit exceeded industry expectations, highlighting its leadership position amid a global boom in AI-driven data center investments.

  • Q3 2025 revenue: KRW 22.2 trillion (26% quarter-on-quarter and 35% year-on-year increase)[1]
  • Operating profit: KRW 9.2 trillion (24% Q-o-Q, 68% Y-o-Y increase)[1]
  • Operating profit margin: 41%[1]
  • Net income: KRW 7 trillion (net profit margin of 31%)[1]
  • EBITDA: KRW 12.6 trillion (EBITDA margin at 57%)[1]

Growth Driven by Artificial Intelligence

The company attributed its profitability to robust market demand for memory chips powering servers that run advanced Chatgpt-like generative AI platforms. The proliferation of AI workloads has boosted shipments of SK Hynix’s HBM products, which are considered essential for training and deploying large AI models. DRAM shipments especially outperformed internal guidance, registering mid-20% sequential growth. NAND shipments also surged over 70% quarter-on-quarter, though average selling prices for NAND slipped by a high single-digit percentage[1].

Strategic Investments and Outlook

SK Hynix reaffirmed its commitment to expanding HBM production and investing in next-generation memory technologies. The company’s strong cash position, with KRW 17 trillion in reserves (up KRW 2.7 trillion from the previous quarter), underpins its aggressive growth strategy. Interest-bearing debt also declined by KRW 1.5 trillion to KRW 21.8 trillion[1].

Market Context

As global tech giants ramp up investment in AI infrastructure, suppliers like SK Hynix are poised to benefit from persistent demand for cutting-edge memory. The company expects sustained revenue growth as AI adoption accelerates worldwide. Its performance in Q3 2025 cements SK Hynix’s pivotal role in the rapidly evolving semiconductor ecosystem, particularly as a critical supplier for Nvidia and emerging AI applications.
