CEO and Chairman Perspective

Russell Ellwanger, Chief Executive Officer, commented: “As pointed out in IC Insights, we moved into the #5 overall foundry position and the #1 position for specialty analog foundries. The #1 position was a movement from #3 in 2009 and #12 back in 2005, when we redirected ourselves to focus on specialty analog. I am thrilled with the many strong partnerships that we have built with our trusted and growing customer base propelling us into the #1 position among our peer group. There is great excitement among our multi-national employee base to take on new significant challenges."

Amir Elstein, Chairman of the Board of Directors of TowerJazz, stated: “I would like to congratulate the management team led by Russell, as well as all the employees of TowerJazz for a record and quite a remarkable year. In only a few years, the company has successfully transformed itself into the specialty market leader. This leadership team is now well positioned to exceed the next big challenge of increasing our revenue to beyond a billion dollars, with the accompanying bottom-line performance.”
