Superior Industries Addresses NYSE Continued Listing Standards

SOUTHFIELD, MICHIGAN –June9, 2020 –Superior Industries International, Inc. (NYSE:SUP), one of the world’s leading aluminum wheel suppliers for OEMs and the European aftermarket, announced today that on June 5, 2020, it received notice (the “Notice”) from the New York Stock Exchange (“NYSE”) that it currently is not in compliance with the continued listing standards set forth in Section 802.01B of the NYSE’s Listed Company Manual due to the fact that the Company’s average global market capitalization over a consecutive 30trading-day period was less than $50 million and, at the same time, its shareholders’ equity was less than $50 million.

The Notice has no immediate impact on the listing of the Company’s common stock, does not affect the Company’s ongoing business operations or its reporting obligations with the Securities and Exchange Commission, and does not conflict with or cause an event of default under any of the Company’s debt or other agreements.

As a result of the Notice, the Company became subject to the procedures set forth in Rule 802.02 of the NYSE Listed Company Manual and in accordance with such procedures, the Company intends to submit a business plan within 45 days of receipt of the Notice that demonstrates the Company’s ability to resume compliance with the continued listing standards. Upon receipt of this plan, the NYSE will have up to 45 days to review and determine whether the Company has made a reasonable demonstration of its ability to come into conformity with the listing standards. If the plan is accepted by the NYSE, the Company would be subject to ongoing quarterly monitoring for compliance with the plan and have up to 18 months from July 1, 2020 to demonstrate compliance. If the plan is not accepted, or if the Company fails to maintain compliance with the plan, the Company would be subject to delisting proceedings.

The Company remains confident in its business prospects and liquidity position and believes that it will successfully resume compliance with the NYSE’s continued listing standards. For reference, the market capitalization of the Company was above $50 million prior to the stock market decline triggered by the COVID-19 pandemic and as of the close of business on June 8, 2020, Superior’s market capitalization was $54 million.
