SK Hynix Lines up $8B EUV Order with ASML

Why It Matters

The investment secures critical EUV capacity for SK Hynix, bolstering its ability to supply AI‑driven data‑center workloads and strengthening its competitive position against Samsung and Micron.

Key Takeaways

• SK Hynix orders up to 20 EUV scanners from ASML
• Deal worth KRW11.95 trillion (~$8 billion) over two years
• Each scanner costs roughly KRW500bn (~$385m)
• SK Hynix capex likely to rise, mid‑30% revenue ratio
• Samsung’s 2026 capex projected at KRW110tn (~$85bn)

Pulse Analysis

The EUV lithography wave is reshaping the memory market, and SK Hynix’s latest commitment signals a decisive shift toward advanced node production. By locking in up to 20 EUV scanners, the Korean chipmaker can transition from legacy deep‑ultraviolet tools to the finer patterning required for high‑bandwidth DRAM and next‑generation NAND. This move not only accelerates its roadmap but also aligns with the broader industry push to support AI workloads, where memory bandwidth and density are paramount. The procurement, valued at roughly $8 billion, reflects SK Hynix’s willingness to invest heavily in cutting‑edge equipment to stay ahead of demand cycles.

ASML, the sole supplier of EUV machines, is experiencing an unprecedented order backlog, with EUV systems now accounting for 65% of its projected sales. The SK Hynix order adds to a pipeline already buoyed by data‑center expansion and AI‑driven compute growth, which are driving memory manufacturers to scale capacity quickly. While the contract does not include ASML’s latest high‑NA tools, it still represents a substantial infusion of high‑precision lithography capacity that will be operational by 2027, reinforcing the symbiotic relationship between equipment makers and memory producers.

Competitive dynamics intensify as Samsung announces a 22% rise in 2026 capex to KRW110 trillion (~$85 billion), earmarking the majority for its Device Solutions division. SK Hynix’s mid‑30% capex‑to‑revenue target suggests a similarly aggressive spend, positioning both firms to capture a larger share of the memory market’s growth. For investors, these capital commitments signal confidence in sustained demand from cloud providers, AI developers, and consumer electronics, while also highlighting the capital‑intensive nature of staying at the technological frontier in semiconductor manufacturing.
