Air Liquide
Foreign listing — not directly tradable in a US brokerage. Editorial detail only.

Owns CryoConcept (mid-tier dilution-fridge maker). Manages industrial gases including strategic helium reserves.

What they do

French industrial gas major. Owns CryoConcept , a mid-tier dilution refrigerator maker, and manages strategic helium reserves — the cryogen that feeds everything in quantum. Lower-purity exposure to the quantum picks-and-shovels thesis through a diversified industrial gas business. Lower beta, lower upside, but a real (if buried) call option on helium-3 economics over the next decade.
