Item 2.02 Results of Operations and Financial Condition

On August 5, 2015, Superior Industries International, Inc. (“Superior,” “we,” “us” or “our”) issued a press release announcing the results of our operations for the second quarter of 2015 and providing information relating to our webcast being held to discuss such results. The information contained in Exhibit 99.1 hereto shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section or incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such a filing.

This Current Report on Form 8-K contains statements that are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements include all statements that do not relate solely to historical or current facts and can generally be identified by the use of future dates or words such as “may,” “should,” “could,” “will,” “expects,” “seeks to,” “anticipates,” “plans,” “believes,” “estimates,” “intends,” “predicts,” “projects,” “potential” or “continue” or the negative of such terms and other comparable terminology. These statements also include, but are not limited to, the 2015 outlook and projections for reported net sales, value-added sales, EBITDA margin, capital expenditures and the change in working capital, and improving cost performance and operational efficiencies, and are based on current expectations, estimates and projections about the company’s business based, in part, on assumptions made by management. These statements are not guarantees of future performance and involve risks, uncertainties and assumptions that are difficult to predict. Therefore, actual outcomes and results may differ materially from what is expressed or forecasted in such forward-looking statements due to numerous factors, risks and uncertainties discussed in the company’s Securities and Exchange Commission filings and reports, including the company’s 2014 Annual Report on Form 10-K and our reports from time to time filed with the Securities and Exchange Commission. You are cautioned not to unduly rely on such forward looking statements when evaluating the information presented in this report. Such forward-looking statements speak only as of the date on which they are made and Superior does not undertake any obligation to update any forward-looking statement to reflect events or circumstances after the date of this report.
