Company Description
Superior Industries International, Inc. (historically traded on the New York Stock Exchange under the symbol SUP) is an automotive manufacturing company focused on aluminum wheels. According to company disclosures and public filings, Superior is described as one of the world’s leading aluminum wheel suppliers. The company’s team works with customers to design, engineer, and manufacture aluminum wheel products using light weighting and finishing technologies for the automotive sector.
Superior is headquartered in Southfield, Michigan. In regulatory filings and news releases, the company is associated with the Manufacturing sector and the motor vehicle gasoline engine and engine parts manufacturing industry classification. Its business centers on aluminum wheels for vehicle manufacturers and on aftermarket brands in Europe.
Business focus and products
Across multiple earnings releases and NYSE-related notices, Superior states that it collaborates with customers to design, engineer, and manufacture a variety of aluminum wheel products. These products are positioned for major vehicle platforms and are tied to what the company describes as a portfolio of high-quality wheel technologies. The company also notes that it utilizes light weighting and finishing technologies in its wheel manufacturing processes.
Superior serves the European aftermarket through the brands ATS®, RIAL®, ALUTEC®, and ANZIO®. These brands are repeatedly cited in the company’s news releases and form a key part of its aftermarket presence in Europe.
Geographic and market presence
Superior’s public communications emphasize its role as an aluminum wheel supplier to the automotive industry and its aftermarket activities in Europe. While earlier descriptions reference operations in the United States and Mexico, more recent news focuses on the company’s global customer relationships and its European aftermarket brands. The company has also discussed a localized manufacturing footprint in regions such as Mexico and Poland in the context of industry trends and supply chain localization, but detailed plant-level information is not provided in the excerpts here.
Capital markets and trading status
Superior’s common stock was listed on the New York Stock Exchange under the symbol SUP. On June 24, 2025, the NYSE notified the company that it would immediately suspend trading in the common stock and commence delisting proceedings after Superior fell below the NYSE’s continued listing standard requiring an average global market capitalization of at least $15 million over a consecutive 30 trading day period, as disclosed in the company’s Form 8-K dated June 25, 2025. The company stated that it did not intend to appeal the NYSE’s determination.
On June 25, 2025, the NYSE filed a Form 25 (Form 25-NSE) with the SEC to remove Superior’s common stock from listing and registration on the NYSE. According to the company’s filings, the delisting became effective ten days after the Form 25 was filed. The same filings state that the common stock began trading on the OTC Pink Market on June 25, 2025 under the ticker symbol SSUP. The deregistration of the common stock under Section 12(b) of the Securities Exchange Act of 1934 is expected to become effective 90 days after the filing of the Form 25, or such shorter period as the SEC may determine.
Planned merger and ownership structure
On July 8, 2025, Superior entered into an Agreement and Plan of Merger with SUP Parent Holdings, LLC (Parent) and SUP Merger Sub, Inc., as disclosed in the company’s Form 8-K and subsequent Form 8-K/A. Under this agreement, Merger Sub will merge with and into Superior, with the company surviving as a direct wholly owned subsidiary of Parent, which is affiliated with lenders under Superior’s existing term loan agreement.
At the effective time of the merger, each outstanding share of common stock (other than excluded and dissenting shares) is to be converted into the right to receive $0.09 per share in cash,> as described in the merger filings. Each outstanding Series A Preferred Share is to receive a specified cash amount and units of Parent such that former holders of all Series A Preferred Shares would hold, in the aggregate, 3.5% of Parent’s common equity, subject to the terms of the Merger Agreement. The merger remains subject to customary conditions, including stockholder approval and regulatory consents, and the filings note that the transaction could be terminated under specified circumstances.
Financial reporting and non-GAAP measures
Superior continues to file periodic reports with the SEC. In its earnings releases, the company presents both GAAP results and several non-GAAP financial measures. These include Adjusted EBITDA, Value-Added Sales, Value-Added Sales Adjusted for Foreign Exchange, Free Cash Flow, Unlevered Free Cash Flow, and Net Debt. The company provides definitions and reconciliations for these measures in its earnings materials and states that management uses them for planning, forecasting, and analysis of financial performance.
For example, Value-Added Sales is defined as net sales less the value of aluminum and certain other costs included in net sales, while Adjusted EBITDA is defined as earnings before interest, taxes, depreciation, amortization, and specified additional items such as restructuring charges, certain transaction-related costs, and changes in fair value of certain derivatives. These non-GAAP metrics are presented alongside GAAP measures to give additional perspective on operating performance and cash generation, according to the company’s disclosures.
Recent strategic and capital structure developments
Superior’s recent news releases describe efforts to address its capital structure and liquidity. In 2024, the company announced the refinancing of its existing senior secured term loan and the planned redemption of its senior notes, extending term loan maturities to December 2028 and attracting capital from several institutional lenders. The company has also reported on a broader transformation of its European operations and initiatives to reduce overhead and capital intensity, as summarized in its 2024 and 2025 earnings releases.
In its first quarter 2025 results, Superior disclosed that certain larger North American OEM customers notified the company of their intent to resource outstanding purchase orders to another supplier, which the company stated would create short-term liquidity constraints and affect its ability to meet certain financial covenants. In response, Superior reported entering into a commitment letter with its term loan lenders for access to additional term loans and covenant relief, subject to conditions, and engaging in advanced discussions regarding a recapitalization transaction designed to significantly reduce outstanding debt by exchanging debt for common stock and address preferred equity, as described in the company’s May 12, 2025 earnings release.
Status of SUP ticker and historical context
For investors researching the historical NYSE-listed security SUP, it is important to note that the ticker was delisted from the NYSE following the Form 25 filing on June 25, 2025, and trading transitioned to the OTC Pink Market under the symbol SSUP. The company’s SEC filings describe ongoing plans for a merger that would result in Superior becoming a wholly owned subsidiary of SUP Parent Holdings, LLC, with public common stockholders receiving cash consideration per share if the merger is completed as outlined.
As a result, the SUP symbol primarily represents the company’s historical listing on the NYSE and its legacy as a publicly traded aluminum wheel manufacturer. Current trading activity and corporate actions are associated with the OTC symbol SSUP and with the proposed merger structure described in the company’s 8-K and 8-K/A filings.
