(ticker: CTAM) is a global distributor of specialty metals and provider of supply chain solutions, principally serving OEMs in the aerospace, industrial, oil and gas, medical, defense, and heavy equipment sectors. Founded in 1890 and headquartered in Oak Brook, Illinois, the company offers a broad portfolio of high-performance metals including alloy steels, stainless steels, nickel alloys, aluminum, carbon steels, titanium, and cobalt alloys in formats such as bars, plates, sheets, tubes, and extruded shapes; it provides value-added processing services encompassing precision cutting, sawing, slitting, grinding, machining, heat treating, trepanning, boring, surface finishing, testing, and just-in-time delivery. Operating through trusted brands and divisions like Castle Metals Aerospace, Castle Metals Industrial, Supra Alloys, Banner Commercial, Banner P&M Supply, Banner Medical Innovations, National Kwikmetal Service (NKS), and Edge International, A.M. Castle maintains an extensive network of over 30 service centers and sales offices across North America (USA, Canada, Mexico), Europe, the Middle East, Africa, and Asia-Pacific, with a focus on quality certifications such as ISO and Nadcap. In a major strategic development, MiddleGround Capital acquired A.M.
