SUPERIOR INDUSTRIES INTERNATIONAL URGES SHAREHOLDERS TO VOTE THE WHITE PROXY CARD IN CONNECTION WITH AUGUST 15 ANNUAL MEETING OF SHAREHOLDERS Company Issues Letter Urging Shareholders to Vote for Board's Qualified, Experienced Slate of Nominees VAN NUYS, Calif., July 28, 2014 - Superior Industries International, Inc. (NYSE: SUP), the largest manufacturer of aluminum wheels for passenger cars and light-duty vehicles in North America, today issued the following letter to shareholders in connection with its Annual Meeting of Shareholders to be held August 15, 2014:

July 28, 2014

YOUR VOTE IS IMPORTANT VOTE THE ENCLOSED WHITE PROXY CARD TODAY!

Dear Fellow Shareholder:

The Board of Directors of Superior Industries International, Inc. urges all shareholders to sign and return the enclosed WHITEproxy card TODAY and vote FOR ALLfour of your Board's highly qualified and very experienced nominees - Paul J. Humphries, James S. McElya, Donald J. Stebbins and Francisco S. Uranga - standing for election at the Annual Meeting of Shareholders to be held on Friday, August 15, 2014.

You may also vote by phone or Internet by following the instructions on the enclosed WHITEproxy card. We also urge you to discard any blue proxy card or voting instruction card you receive 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 you previously signed a blue proxy card sent to you by GAMCO, you can revoke that proxy card and vote for your Board's recommended nominees by voting a new WHITEproxy card. Only your latest-dated proxy will count.

DB1/ 80102853.2

PLEASE VOTE THE WHITE PROXY CARD TODAY!

We remain very disappointed that GAMCO is forcing upon Superior a costly and distracting proxy contest that seeks to replace three highly qualified and valued members of your Board with its own candidates, who have no executive-level manufacturing or relevant automotive industry experience whatsoever. In fact, GAMCO has not provided any arguments as to why its candidates are more qualified than Superior's nominees to address the issues facing Superior, nor has GAMCO stated any specific concerns it has with the directors that its proxy contest would seek to replace. GAMCO has not even indicated which of the four nominees recommended by your Board it is seeking to prevent from being elected.

THE GAMCO NOMINEES HAVE LITTLE RELEVANT EXPERIENCE

We do not believe that any of the GAMCO nominees would bring to Superior's Board any relevant experience, skills or competencies not already present among the current Board members and its newest nominee. Aside from GAMCO's nominees not having any experience working in the automobile industry, none has served as a director of a public company that is comparable in size to Superior, whether measured by market capitalization, revenues or any other measure. All three of GAMCO's nominees have been previously proposed by GAMCO as director nominees at one or more other public companies, none of which is in the automobile industry and none of which is comparable in size to Superior.
In stark contrast to GAMCO'S nominees, we believe that our four highly qualified and experienced nominees, Paul J. Humphries, James S. McElya, Donald J. Stebbins and Francisco S. Uranga, have the integrity, knowledge, breadth of relevant and diverse experience and commitment necessary to navigate Superior through the highly competitive global business environment in which we operate and to deliver value to our shareholders. Each of these nominees was recommended to your Board by the Nominating and Governance Committee and was approved unanimously by your Board.
The recommendations of your Board are based on its carefully considered judgment that the experience, record and qualifications of each of its nominees make them the best candidates to serve on Superior's Board. Each of these nominees, with the exception of our CEO, would qualify as an independent director under the NYSE's independence standards. Of the four nominees being recommended by your Board, only Mr. Uranga was a member of your Board at the time of last year's Annual Meeting, and, if elected, Messrs. Humphries and McElya would be the newest independent Board members. The nomination of these four candidates shows your Board's commitment to enhancing its composition with highly qualified, experienced, business leaders who have deep, relevant experience and fresh perspectives that enhance the breadth and depth of your Board for the benefit of all shareholders.
