SK Hynix has announced that it will bring forward the commissioning of its upcoming M16 memory chip fabrication facility by three months, shifting the start of operations from May to February 2027. This decision follows sustained strength in global DRAM and NAND markets, where industry-wide utilization rates have climbed above 90%. The M16 plant, located in Icheon, South Korea, will initially add 180,000 12-inch wafer starts per month to SK Hynix’s capacity, representing a roughly 10% boost to the company’s total production capability. Management projects that this acceleration will help capture an additional $1.2 billion in revenue during the 2027 fiscal year compared to the original schedule.

In addition to the early M16 startup, SK Hynix confirmed that a second greenfield facility—dedicated primarily to advanced high-bandwidth memory (HBM) modules for AI applications—will commence production in February 2026. This HBM-focused site in Yongin is expected to ramp to full capacity by late 2026, adding another 100,000 wafer starts per month. Executives anticipate that the plant will contribute approximately 20% of the company’s total HBM output by the end of next year, positioning SK Hynix to meet surging demand from cloud providers and data-center operators.

SK Hynix has earmarked $13 billion in capital expenditure for the combined development of these two facilities, reflecting one of the largest one-time investments in the memory sector over the past decade. Roughly $7.5 billion of this budget will fund M16, while the remaining $5.5 billion covers the HBM plant. The allocation includes advanced EUV lithography equipment, next-generation etch and deposition tools, and an expanded in-house R&D center to refine the company’s industry-leading Gate-All-Around (GAA) transistor architecture. Analysts estimate that the incremental capacity and technology upgrades could lift SK Hynix’s gross margin by up to 150 basis points once both fabs reach steady-state utilization.

With these expansions, SK Hynix aims to reinforce its position as the world’s second-largest memory supplier, intensifying competition with Micron Technology in the HBM and AI-optimized memory segments. Industry data indicate that SK Hynix and Micron together control approximately 70% of the global HBM market. By accelerating its schedule, SK Hynix seeks to preempt Micron’s planned capacity increases and potentially capture market share from customers seeking supplies of HBM2E and HBM3 modules. Investors will be watching closely to see whether the faster ramp translates into long-term share gains or prompts a price war that could pressure all major producers’ margins.
