North American Stainless

What North American Stainless does

North American Stainless (NAS) is the largest fully integrated stainless steel producer in the United States, founded in 1990 and headquartered on a 1,600-acre site in Ghent, Kentucky, on the Ohio River. The company operates a single integrated facility encompassing melt shop, hot rolling, cold rolling (including Sendzimir mills), and finishing operations, producing flat products (cold rolled coil/sheet, hot rolled coil/sheet, hot rolled plate, floor plate) and long products (angles, reinforcement bars, round bars, wire rod coils, black bar, hexagonal bars) across austenitic, ferritic, duplex, and martensitic grade families. NAS is a wholly-owned subsidiary of Acerinox Group, a Spanish multinational with 13 factories across five continents, and is governed by the laws of the Commonwealth of Kentucky. Cumulative capex across 13 expansion phases has reached $3 billion and the workforce stands at over 1,700 employees as of October 2025.

The company's revenue model is industrial hardware sales: base product pricing plus alloy surcharges (chrome, nickel) and a dynamic fuel surcharge (currently 49% for flat and long products as of June 1, 2026). Distribution runs through direct enterprise sales via regional sales representatives covering defined U.S., Canada, and Mexico territories, supplemented by five in-house service centers in Georgia, Illinois, Pennsylvania, Apodaca (Mexico), and Guelph (Canada) that provide blanking, slitting, and other processing. End markets are diversified across transportation (automotive, railway, aerospace, maritime), industrial equipment and engineering, ABC and infrastructure, food processing, household appliances, and environmental technology, with certifications spanning AS9100D aerospace, ISO 9001, ISO 14001, ISO 17025, ISO 45001, and ISO 50001 supporting qualification for safety-critical applications. ESG positioning includes EcoVadis Platinum, CDP B grades for Climate and Water, and 2030 targets of 20% reductions in Scope 1+2 carbon intensity and specific water withdrawal plus 90% reduction in landfill waste.

NAS is currently mid-execution on a major capacity expansion and modernization program announced in 2024 that includes a new cold rolling mill, roll grinders, annealing and pickling line upgrade, temper mill, and Melt Shop expansion. Its parent, Acerinox, completed the November 2024 acquisition of Haynes International to extend into high-performance alloys and aerospace, and in April 2025 Clive Grannum succeeded Cristobal Fuentes as CEO after Fuentes' 44-year tenure.

Both companies compete in flat-rolled stainless and specialty steel serving automotive, construction, and industrial customers in the US market.

Others

• Olympic Steel: Olympic Steel is a US-based metal service center that processes and distributes stainless, carbon, and aluminum flat products. While not a mill peer, Olympic competes with NAS's service center network in downstream processing and distribution, and is a relevant comparable for the value-added service center economics embedded in NAS's warehouse operations.
• Acerinox Group: Acerinox Group is the Spanish parent company of NAS and one of the world's largest stainless steel producers with 13 factories across five continents including Columbus Stainless (South Africa), Bahru Stainless (Malaysia), and VDM Metals.
