CEO and Chairman Perspectives

Russell Ellwanger, Chief Executive Officer, commented: “2010 began strongly for TowerJazz and our momentum continues to grow.  To our best visibility, we foresee continued best ever revenue and EBIDTA throughout this year and into 2011.  We have now surpassed a revenue run rate that would achieve $500 annual revenue, which we consider as a major milestone achievement. This quarter was by far the best in TowerJazz’ history, nicely surpassing the combined, best single pro-forma revenue quarters ever achieved by either Tower or Jazz, and as a result of our value add product platforms, service offerings and operational efficiencies the EBIDTA is about 2X of the previously mentioned best pro-forma quarters.  Our bullish optimism for the future is based upon accelerated design-win momentum, which have been realized within a large group of diversified, global customers, many of which being market share and technology platform leaders for their respective markets. We have also taken significant strides to increase our manufacturing capacity so we can service more business, and as we move into the second half of the year, these efforts will bear fruit.” 

Ellwanger further added, “Concurrently, we are taking advantage of our strong business trajectory and cash generation to improve our balance sheet and restructure our debt repayment and credit line terms. The agreements signed this past couple of months with our bondholders and lending banks demonstrate the confidence the financial community has in our company and its long-term strategy.”

Amir Elstein, Chairman of the Board of Directors of TowerJazz, stated: “I am pleased with the continued excellent execution of TowerJazz.  The present quarter record revenue and record EBITDA is important as is our solid growth forecast for the next quarters. What I find remarkable is the continued record growth in design wins which promises a long term best in class performance.”
