Key Facts

1Air Liquide plans to invest nearly EUR 200M in South Korea to support the production of next-generation High Bandwidth Memory (HBM) chips.

Amid the intensifying global race to secure advanced semiconductor supply chains, Air Liquide has announced a strategic expansion in South Korea. The company plans to invest nearly EUR 200 million to support the production of next-generation High Bandwidth Memory (HBM) chips. This investment is structured under a long-term agreement with SK hynix to provide industrial gases essential for the scaling of AI infrastructure.

This partnership strengthens Air Liquide's position in the industrial gas sector, where it competes with peers like Linde and Air Products to capture AI-driven demand. Per market data, this expansion aligns with SK hynix's roadmap to ramp up HBM3E production to meet surging requirements from AI leaders like Nvidia, which recently reported record-breaking data center revenue in its latest quarterly earnings (per Nvidia investor relations).

Regarding market performance, AIQUY shares closed at $38.51 (close June 11, 2026), after reaching a session high of $38.56. Investors are now looking toward upcoming Eurozone economic indicators, such as industrial production data, to gauge the sustainability of capital expenditure among industrial majors in the current interest rate environment.
