Overview

Air Liquide S.A. is a global industrial gases group spanning Large Industries on-site/pipeline supply, Industrial Merchant distribution, Healthcare, Electronics, Engineering & Construction, and Global Markets & Technologies. The core moat in Large Industries is asset- and contract-driven: long-term supply contracts and dense pipeline/on-site networks create localized barriers and stable cash flows. In Electronics, fab qualification requirements and on-site supply infrastructure raise switching costs and support premium positioning. Healthcare benefits from a large field/service footprint serving hospitals and homecare patients, reinforced by regulated quality requirements. Key risks include contract rebid pressure, energy and volume cycles, and policy/technology shifts affecting decarbonized hydrogen and semiconductors.
