Aachen, Germany, April 9, 2013 - The Supervisory Board for AIXTRON SE (Frankfurt Stock Exchange: AIXA; NASDAQ: AIXG), a leading global manufacturer of deposition equipment for the semiconductor industry, proposes Dr. Andreas Biagosch and Dr. Martin Komischke as candidates for election to the AIXTRON Supervisory Board at the 2013 Annual General Meeting.

Dr. Biagosch worked for 28 years as an engineer for the international consulting firm McKinsey & Co. on various international projects for high-tech and other industries and was part of McKinsey's global Shareholder Council. Dr. Biagosch currently works as an independent entrepreneur.

Dr. Komischke, who is also an engineer, is currently Chairman of the Executive Board at Hoerbiger Holding AG, a manufacturer of performance-defining components for mechanical engineering in Switzerland.

The wealth of experience demonstrated by both candidates in sectors relevant to AIXTRON, as well as their international professional experience in consultancy and industry, alongside the knowledge and vocations of the full Supervisory Board, were important factors in the Nomination Committee's decision to select and recommend these individuals. The Supervisory Board is following the recommendation of the Nomination Committee and proposes both candidates to its shareholders for election at the Annual General Meeting to be held in Aachen on May 23, 2013.
