SummaryUpdated Jun 1, 2026
ATI Inc. (NYSE:ATI) is a specialty materials manufacturer that has transformed itself from a diversified metals company into a focused aerospace and defense supplier. Founded in 1960 and formerly known as Allegheny Technologies Incorporated, the company underwent a strategic repositioning following the 2022 Russia-Ukraine conflict, which created significant opportunities in titanium and specialty alloy markets. Headquartered in Dallas, Texas, ATI has evolved into a critical supplier of advanced materials for jet engines, aircraft structures, and defense applications, with aerospace and defense now representing approximately 66% of total revenue as of 2025.
