SK Hynix’s Record Results Point to Tight AI Memory Supply

Record quarter reflects AI memory strength

SK Hynix’s record third-quarter performance indicates that AI-related memory demand is translating into revenue, contracts and unusually high profitability. The company reported revenue of 104.6 trillion won, up 328% from a year earlier, and operating profit of 83.3 trillion won, up 632%, producing an 80% operating margin.

The results were also strong despite currency headwinds. SK Hynix earns mostly in dollars, and the won-dollar rate averaged 1,428.4 won in the third quarter, down about 4.9% from 1,501.9 won in the previous quarter. On $10 billion of revenue, that shift alone would reduce the won value by about 735.5 billion won quarter on quarter. Net income was 39.8 trillion won, up 216% year on year but down 58% sequentially, reflecting 32.6 trillion won of net non-operating expenses, including currency and investment valuation losses.

Contracts make demand more visible

Long-term agreements with 14 major customers, including global cloud providers, reserve more than half of SK Hynix’s 2027 and 2028 production capacity. The contracts typically run for five years, allow prices to move within agreed ranges and include deposits. CEO Kwak Noh-jung said customer trust and technological competitiveness were converting into long-term contracts and improved medium- and long-term demand visibility.

DRAM marketing executive vice president Park Jun-deok said revenue at major hyperscalers grew roughly 30% to 80% year on year, while their order backlogs rose two- to fivefold. He projected AI-related revenue growth would remain solid, while SK Hynix intends to maintain a similar proportion of capacity covered by medium- and long-term agreements.

Supply remains the near-term constraint

SK Hynix expects memory demand to exceed supply through 2030, citing the complexity of leading-edge production and the lead time required for new fabrication facilities. The company said its DRAM and HBM volumes through 2029 are effectively sold out when secured long-term agreements are combined with demand under discussion.

Customers’ current volume requirements were reported to be more than twice what SK Hynix can supply. Some customers have also adjusted HBM specifications, which the company interpreted as evidence that they are building more AI accelerators from limited chip availability. The immediate signal is therefore stronger volume visibility for the supplier, although the reports do not establish how much of future demand will convert into deliveries beyond the contracted periods.

Capacity plans raise the execution test

SK Hynix expects investment to rise significantly in 2027 as the first phase of its Yongin complex enters full-scale operation. Its Cheongju fabrication facility is expected to reach peak capacity within the year, DRAM shipments are projected to rise by more than 20%, and HBM4 is planned to become the flagship product in the fourth quarter. These are company projections rather than realized results.

The next test is whether planned capacity additions and product transitions translate into the anticipated shipments while preserving the profitability associated with long-term contracts and an 80% operating margin.
