SK Hynix commits KRW40T capex for AI memory but delays US, Japan plant plans

SK Hynix announced it is advancing a capital expenditure plan in the high-KRW40s trillion range for 2026, with the primary goal of expanding AI memory capacity. However, the company has not yet decided whether to build new production facilities in the US or Japan—two regions that have attracted substantial semiconductor investment in recent years. Instead, SK Hynix said its approach to overseas expansion will be flexible and driven by multiple factors. The company will evaluate business feasibility, the availability of supporting infrastructure, the strength of the local semiconductor ecosystem, and the specific needs of its customers before committing to new manufacturing locations. This strategy allows SK Hynix to maintain optionality as market conditions and geopolitical circumstances evolve, while still signaling its intent to invest heavily in expanding global AI memory capacity.

SK Hynix's announcement reflects a strategic pause in committing to specific overseas manufacturing locations even as it ramps up overall investment in AI memory production. The company's stated criteria—business feasibility, infrastructure, semiconductor ecosystem strength, and customer demand—suggest it is waiting for clearer signals from customers and host governments before choosing between the US, Japan, and potentially other regions. This measured approach is common among memory chip makers, which must balance the enormous cost of new fabs (semiconductor factories) against uncertain demand cycles and geopolitical factors. By keeping its options open while increasing its capex commitment, SK Hynix is positioning itself to deploy capacity where conditions are most favorable, rather than locking into locations prematurely.
