SK Hynix posts record 2025 profits — 97T KRW revenue, $33B profit, focuses on AI

SK Hynix said 2025 was its best year ever, reporting 97 trillion KRW in revenue (about $67 billion) and $33 billion in profits, with operating margins of 49%, according to the company’s latest financial results. The firm highlighted progress on high-bandwidth memory, saying it had "successfully completed the preparation stages to mass produce HBM4 – for the first time in the industry – in September last year," and that large-scale production of the next-generation HBM is underway to meet customer requests.

On conventional DRAM, SK Hynix said it intends to accelerate the transition to the 1 cnm process and expand its AI memory portfolio with solutions like SOCAMM2 and GDDR7 — a message the report frames as largely aimed at AI and enterprise customers (the piece also notes Nvidia uses GDDR7 for gaming graphics cards).

For NAND flash, SK Hynix said it "plans to maximize product competitiveness by transitioning to 321-layer technology, while actively addressing AI data center storage demand by leveraging Solidigm’s QLC eSSD," underscoring the company’s focus on AI-related storage and memory markets.

The company announced a roughly $700 million special dividend (about $1 per share), and said that combined with the regular quarterly dividend the year-end payout amounts to $1.45 billion (about $1.30 per share).
