New Air Separation Plant to Be Built in Las Vegas, Nevada, USA

Nippon Sanso Holdings Corporation (“NSHD”, President CEO: Toshihiko Hamada) today announced that its U.S. operating company, Matheson Tri-Gas, Inc. (“MATHESON”, headquartered in Irving, Texas), will build, own, and operate a new air separation plant in Las Vegas, Nevada, which is scheduled for completion in 2027. This new plant will strategically strengthen MATHESON’s national network of air separation plants, particularly in the rapidly growing U.S. Sunbelt region.

The new plant will produce oxygen, nitrogen, and argon to meet increasing demand for liquid gases in the medical, fabrication, construction, and food processing industries across Nevada, California, Utah, and Arizona. The addition of this new plant will further enhance our U.S. capabilities in packaged gases, specialty gases, nitrous oxide, dry ice, helium, and HyCO (hydrogen and carbon monoxide) supply.

NSHD and MATHESON remain committed to supporting the growth and development of key industries in the region by providing a stable and reliable supply of essential industrial gases.
