SK Hynix achieved its highest-ever quarterly performance, driven by expanding demand for AI memory. Profitability improved significantly as sales of high value-added products increased and prices rose, and cumulative sales for the first half of the year exceeded 100 trillion won for the first time in history.

SK Hynix announced its second-quarter 2026 business results on the 29th.

The company recorded sales of 79.3187 trillion won, an operating profit of 60.5426 trillion won (operating profit margin of 76%), and a net profit of 93.9226 trillion won (net profit margin of 118%). Compared to the same period last year, sales increased by 257% and operating profit by 557%. Compared to the previous quarter (Q1 2026), sales increased by 51% and operating profit by 61%.

The company announced that both DRAM and NAND flash recorded significant price increases, following the previous quarter.

The explanation is that profitability was boosted by increasing sales of high-value-added products, such as HBM, DRAM for AI servers, and eSSDs.

At the end of the second quarter, cash equivalents recorded 88 trillion won, an increase of 33.6 trillion won from the previous quarter, and borrowings decreased to 18.6 trillion won, expanding net cash to 69.4 trillion won.

The company stated that HBM4 has secured power efficiency and cost competitiveness while implementing the operating speeds required by customers.

Mass production shipments began in the second quarter, and there are plans to significantly expand production in the second half of the year.

HBM4E, for which sample supply was completed in the first half of the year, utilizes a process equipped with technological maturity and mass production stability.

SOCAMM2 sales increased significantly in the second quarter, and supply of products using the 10-nanometer class 6th generation (1c) process also began.

SK Hynix announced that it has concluded negotiations for Long Term Agreements (LTAs) with about 10 customers, including key customers, and is continuing additional discussions.

In the NAND sector, 321-layer products accounted for the largest share of total production...., and plans to expand to 50% of domestic production capacity by the end of the year.

We are accelerating the mass production schedule for the M15X and simultaneously investing to rapidly expand production capacity after the opening of the Yongin Phase 1 fab cleanroom in early 2027.

Mid-to-long-term investments, such as the advanced packaging plant P&T7, the NAND production base M17, and the establishment of a new semiconductor cluster, are planned to be implemented in stages, taking into account customer demand and investment efficiency.
