Company Description
Superior Industries International, Inc. (SSUP) is an auto parts company focused on the design, engineering, and manufacturing of aluminum wheels for the automotive industry. The company is described in its public communications as one of the world’s leading aluminum wheel suppliers, emphasizing collaboration with customers and the production of high-quality, cost-competitive wheels. Superior operates within the consumer cyclical sector and auto parts industry.
According to company disclosures, Superior’s team works with customers to design, engineer, and manufacture a wide variety of aluminum wheel products that use light weighting and finishing technologies. These technologies are highlighted in the company’s descriptions as important to its product offering. Superior also serves the European aftermarket through the brands ATS®, RIAL®, ALUTEC®, and ANZIO®.
Superior is headquartered in Southfield, Michigan. The company’s common stock was previously listed on the New York Stock Exchange under the symbol SUP. On June 24, 2025, the New York Stock Exchange determined that Superior no longer met its continued listing standard relating to average global market capitalization. A Form 25 was filed on June 25, 2025 in connection with the delisting of the common stock from the NYSE. Ten days after that filing, the delisting became effective, and the deregistration of the common stock under Section 12(b) of the Securities Exchange Act of 1934 became effective after the applicable period.
Following the NYSE suspension and delisting proceedings, Superior’s common stock began trading on the OTC Pink Market (often referred to as the pink sheets) on June 25, 2025 under the ticker symbol SSUP. Company communications state that Superior is listed on the OTC Pink Limited Exchange.
Superior has also undergone a significant corporate transaction affecting its public company status. On July 8, 2025, Superior Industries International, Inc., SUP Parent Holdings, LLC (referred to as Parent), and SUP Merger Sub, Inc. entered into an Agreement and Plan of Merger. Under this agreement, Merger Sub merged with and into Superior, with Superior continuing as the surviving corporation and becoming a direct, wholly owned subsidiary of Parent. The merger was completed on December 8, 2025, as disclosed in a Form 8-K filed by the company.
At the effective time of the merger, each share of Superior’s common stock and each Series A preferred share that was issued and outstanding immediately prior to the effective time (subject to specified exceptions) was converted into the right to receive cash consideration as described in the merger agreement and the company’s Form 8-K. As a result of the merger, a change of control occurred and Superior became a direct, wholly owned subsidiary of Parent. Holders of such shares ceased to have rights as stockholders of Superior, other than the right to receive the applicable merger consideration.
In connection with the completion of the merger, Superior disclosed that it intended to file a certification on Form 15 with the U.S. Securities and Exchange Commission to terminate the registration of its common stock under Section 12(g) of the Securities Exchange Act of 1934 and to suspend its reporting obligations under Sections 13 and 15(d) of the Exchange Act. On December 19, 2025, Superior filed a Form 15 certifying the termination of registration of its common stock and the suspension of its duty to file periodic reports under the Exchange Act. The Form 15 notes that, as of the certification date, there was one holder of record of the covered class of securities.
These regulatory filings and transaction disclosures indicate that Superior Industries International, Inc. transitioned from a publicly traded company with common stock listed on the NYSE to a privately held company that is a wholly owned subsidiary of SUP Parent Holdings, LLC. The Form 15 filing confirms the termination of registration and the suspension of periodic reporting obligations for its common stock.
In its public descriptions, Superior emphasizes its role in the global wheel industry and its work with customers and suppliers. The company has referenced a broad portfolio in the industry and a strategically advantaged footprint in its communications about its capital structure and merger transaction. It has also highlighted demand for high-quality, cost-competitive, in-region manufacturing capacity and the importance of responding to supply chain and tariff dynamics, as described in its transaction-related press releases.
Business focus and industry role
Superior’s core business focus, as described in its own materials, is supplying aluminum wheels to automotive customers. The company’s communications highlight collaboration with customers on wheel design and engineering, as well as manufacturing capabilities that use light weighting and finishing technologies. These attributes are presented as central to its position in the wheel industry.
In the European aftermarket, Superior’s presence is associated with the brands ATS®, RIAL®, ALUTEC®, and ANZIO®. These brands are specifically mentioned in company descriptions as part of its aftermarket offering.
Public company history and trading status
Superior’s common stock was previously traded on the New York Stock Exchange under the symbol SUP. On June 24, 2025, the NYSE determined that Superior had fallen below its continued listing standard requiring an average global market capitalization over a consecutive 30 trading day period of at least a specified threshold. As a result, the NYSE suspended trading in Superior’s common stock and initiated delisting proceedings. The company stated that it did not intend to appeal the NYSE’s delisting determination.
Upon suspension of trading on the NYSE, Superior stated that it expected its common stock to trade publicly on the OTC Pink Market operated by OTC Markets Group, Inc. under the ticker symbol SSUP beginning on June 25, 2025. Company disclosures confirm that the common stock began trading on the OTC Pink Market on that date under the symbol SSUP.
Merger and transition to private ownership
The Agreement and Plan of Merger dated July 8, 2025, between Superior, SUP Parent Holdings, LLC, and SUP Merger Sub, Inc. provided for the merger of Merger Sub with and into Superior, with Superior surviving as a wholly owned subsidiary of Parent. A Form 8-K filed on December 8, 2025 states that the merger was consummated on that date. Immediately prior to the effective time of the merger, Parent held common shares representing approximately 17.6% of the total voting power of the company.
At the effective time of the merger, each outstanding common share and each Series A preferred share (subject to specified exceptions) was converted into the right to receive cash consideration as set forth in the merger agreement. Following the merger, Superior became a direct, wholly owned subsidiary of Parent, and a change of control of Superior occurred. The company also entered into amendments to its term loan and revolving credit agreements and an exchange and contribution agreement in connection with the transaction, as described in the same Form 8-K.
Subsequently, on December 19, 2025, Superior filed a Form 15 with the SEC to terminate the registration of its common stock under Section 12(g) of the Exchange Act and to suspend its reporting obligations under Sections 13 and 15(d). The Form 15 notes that the merger had been completed on December 8, 2025 and that Superior was a direct, wholly owned subsidiary of SUP Parent Holdings, LLC.
Company status for investors and researchers
For investors and researchers reviewing the historical SSUP stock, it is important to recognize that Superior Industries International, Inc. has been acquired and is no longer an independent, exchange-listed public company. Its common stock was delisted from the NYSE following the Form 25 filing and later deregistered under the Exchange Act following the Form 15 filing. The merger transaction and subsequent deregistration mean that historical trading in SSUP relates to a company that has since become privately held.
Historical descriptions of Superior’s business as an aluminum wheel supplier, its headquarters in Southfield, Michigan, and its European aftermarket brands remain relevant for understanding the company’s operations prior to its transition to private ownership. However, ongoing financial reporting to the SEC has been suspended as a result of the Form 15 filing, and the company’s common stock is no longer registered under Section 12(g) of the Exchange Act.
