SUPERIOR INDUSTRIES URGES SHAREHOLDERS TO VOTE THE WHITE PROXY CARD FORALL SUPERIOR'S DIRECTOR NOMINEES AT MAY 5, 2015 ANNUAL MEETING

All Three Leading Independent Proxy Advisory Firms Recommend

That Shareholders Vote FORALL Superior's Board Nominees

SOUTHFIELD, MICHIGAN - May 1, 2015 - Superior Industries International, Inc. (NYSE:SUP), the largest manufacturer of aluminum wheels for passenger cars and light-duty vehicles in North America, is urging its shareholders to vote the WHITEproxy card FORALLseven of its director nominees at the Company's upcoming 2015 Annual Meeting of Shareholders, to be held next week, on Tuesday, May 5,

2015.

As previously announced, all three of the leading independent proxy advisory firms- ISS Proxy Advisory Services, Glass, Lewis & Co., LLC, and Egan-Jones-have recommended that shareholders vote the WHITEproxy card FORALLSuperior's highly qualified and experienced director-nominees - Margaret S. Dano, Jack A. Hockema, Paul J. Humphries, James S. McElya, Timothy C. McQuay, Donald J. Stebbins and Francisco S. Uranga. Commenting on the upcoming 2015 Annual Meeting, Superior issued the following statement: "We are very pleased that ISS, Glass Lewis and Egan-Jones, the three leading independent, third-party proxy advisory firms, have carefully reviewed the voting alternatives and all three have recommended that shareholders should vote for all seven of Superior's director nominees on the WHITEproxy card. As we have stated consistently, we do not believe that any of GAMCO's nominees can be said to have experience comparable to that of any of the three highly qualified and very experienced members of the Superior Board that GAMCO is seeking to replace. As was the case with GAMCO's previous two unsuccessful proxy contests against Superior, not one of GAMCO's nominees has any executive-level manufacturing, automotive industry, supply chain management, global markets or global operations experience, and we do not believe that any of GAMCO's nominees would bring to Superior's Board any relevant insights, perspectives, skills or competencies not already present among the current members of the Superior Board. In addition, none of GAMCO's nominees have any experience navigating a company the size and global reach of Superior through the complex, dynamic and highly competitive global business environment in which we operate." Superior shareholders are reminded that their vote is extremely important, no matter how many or how few shares they own. Shareholders may vote by returning the WHITEproxy card or by phone or Internet by following the instructions on the WHITEproxy card they have received. Shareholders are urged to

discard any blue proxy card or voting instruction card they may have received from GAMCO. Even a WITHHOLD vote with respect to GAMCO's nominees on its blue proxy card will cancel any proxy previously given to Superior. If a shareholder previously signed a blue proxy card sent by GAMCO, that proxy card can be revoked by voting a new WHITEproxy card for the Board's recommended nominees. Only the latest-dated proxy will count.

Superior is being advised in connection with the proxy contest by Winston & Strawn, LLP and Morgan,
Lewis & Bockius LLP. Mackenzie Partners, Inc. is serving as Superior's proxy solicitor.
