Aixtron makes and sells CVD equipment, including that for growth of graphene. Its shares are listed on NASDAQ under the symbol AIXG. The stock has had its ups and downs in the past few years and has been steady since the fall of 2011. Many graphene-producing companies and research groups use Aixtron machines and graphene-related sales seem to be picking up for Aixtron, however at the end of Q3 of 2012 the company announced EUR 51.5m of inventory write-downs, due to lower-than-expected overall sales. The revenues dropped 68% compared to the same 9-month period of 2011. I wouldn’t invest in the stock right now.
