SK Hynix (SKHY) shares climbed 12.35% to $163.31, a gain of $17.95, as strong buying followed the South Korean memory maker's record third-quarter results. The rally came on the back of all-time-high quarterly revenue and operating profit, fueled by rising demand for artificial intelligence memory. Alongside the earnings report, the chipmaker unveiled substantial shareholder return plans and a roadmap to expand production capacity.

Record Revenue and Operating Profit

SK Hynix posted third-quarter revenue of 104.62 trillion won, marking its first quarterly result above the 100 trillion won threshold. Revenue increased 32% from the previous quarter and surged 328% compared with the same period a year earlier.

Operating profit reached 83.33 trillion won, climbing 38% quarter over quarter and 632% year over year. The company's operating margin came in at 80%, up from 76% in the second quarter and 47% a year ago — a margin that stands out even by the standards of past memory-industry booms, underscoring how far pricing and product mix have shifted toward high-value segments. Net income, however, fell 58% quarter over quarter to 39.78 trillion won, though it was still up 216% annually.

The results reflect robust demand for advanced memory products used in AI servers and data centers. SK Hynix attributed its performance to higher prices for key products and growing sales of high-value memory. Server DDR5 shipments underpinned DRAM revenue, while HBM4 — high-bandwidth memory, the premium stacked-chip format widely used in AI server builds — began ramping during the quarter. Demand for 321-layer triple-level cell enterprise solid-state drives also supported NAND sales.

AI Memory Shortage Underpins Expansion Plans

SK Hynix expects memory demand to outpace supply through 2030 as AI infrastructure investment expands. The company identified enterprise AI, personal AI, autonomous driving, and robotics as important sources of future memory demand. At the same time, it cautioned that advanced manufacturing requirements and lengthy factory construction timelines could limit the industry's ability to increase supply quickly — a structural tension that explains why the company's capacity roadmap and customer commitments carry weight beyond a single earnings cycle.

To address rising demand, SK Hynix plans to increase production using its sixth-generation 10-nanometer-class process technology. The company also intends to expand sales of DDR5 and LPDDR5 SOCAMM modules for AI servers and to bring its M15X facility to maximum capacity by year-end to boost HBM4 output.

SK Hynix expects HBM4 to overtake HBM3E in both shipment volume and revenue during the fourth quarter. It also plans to raise the share of 321-layer NAND to more than half of its domestic production capacity. These measures are designed to strengthen the company's position in high-performance memory and enterprise storage markets.

Long-Term Contracts and Shareholder Returns Anchor Growth Strategy

Memory markets have historically swung between shortages and gluts, making forward visibility one of the industry's scarcest resources. Against that backdrop, SK Hynix has signed long-term agreements with 14 major customers, including leading global cloud service providers. The contracts cover more than 50% of the company's total production capacity for 2027 and 2028, improving demand visibility and allowing production to be planned around customer requirements.

The company also expects to increase investment significantly next year as the first phase of its Yongin facility advances. Management said it will adjust investment levels according to demand, profitability, product competitiveness, and capital efficiency, linking capacity expansion decisions to market conditions.

For fiscal 2026, SK Hynix announced approximately 100 trillion won in total shareholder returns — a sum roughly on par with the company's record quarterly revenue — comprising at least 30 trillion won in cash dividends and at least 60 trillion won in share repurchases and cancellations. The board also approved a third-quarter dividend of 20,000 won per share, including a special dividend reflecting gains from its Kioxia investment.

The company completed a previously announced 40 trillion won share repurchase and plans to cancel those shares shortly. It additionally approved another 20 trillion won buyback, with 10 trillion won allocated for cancellation and the remainder designated for employee compensation.

Record earnings, expanding AI memory demand, and substantial shareholder returns together form the central drivers behind SK Hynix's latest stock rally. The company's own outlook supplies the near-term markers to watch: whether HBM4 overtakes HBM3E in shipment volume and revenue in the fourth quarter, whether the M15X facility reaches maximum capacity by year-end, and how next year's investment is calibrated as the Yongin first phase progresses.
