What Superior Industries International, Inc. does

Superior Industries International, Inc. is a US-based automotive components manufacturer recognized as the largest producer of aluminum alloy wheels for passenger cars and light-duty vehicles in North America. Founded in 1957 and headquartered in Southfield, Michigan, the company operated with 5,001-10,000 employees and was previously listed on the NYSE under ticker SUP before being delisted following its December 2025 acquisition. Its core technology centers on aluminum alloy wheel manufacturing with a focus on high recycled content and lightweighting, including proprietary alloy development such as the AlSi7Mg0.3 composition designed to optimize strength, weight, and durability for high-performance wheel applications.

The company supplies aluminum wheels directly to automotive OEMs as a tier-1 supplier, embedding components into vehicle production programs. Notable engagements include participation in Jaguar Land Rover's Project Cornerstone sustainability program, supplying high recycled content wheels for Range Rover vehicles. Its products address three primary OEM pain points: vehicle lightweighting for fuel efficiency and EV range optimization, sustainability mandates requiring reduced carbon footprint in production, and supply chain resilience for luxury vehicle manufacturing. Manufacturing operations utilize 100% renewable energy, and the company participates in multi-component sustainability initiatives achieving over 1 ton of CO2 equivalent savings per demonstration vehicle.

Superior Industries generates revenue primarily through hardware sales of aluminum alloy wheels to automotive OEMs, with a secondary aftermarket/retail segment serving customization and performance upgrade demand. Production facilities are designed for annual capacities of 500,000 to 2 million units, with stated target gross profit margins of 25-35%. However, realized 2024 gross margin was approximately 8.7%, well below target. The company was acquired in December 2025 by a group of its existing term loan investors via a debt-to-equity conversion, ending its public company status following consecutive net losses of approximately $93M (2023) and $78M (2024) and a revenue decline from $1,640M (2022) to $1,267M (2024).
