MIGDAL HAEMEK, Israel, December 21, 2009 -- TowerJazz, the global specialty foundry leader, today announced it expects fourth-quarter revenue to exceed the company's previous guidance given on November 9, 2009 due to successful completion of the first milestone in its Asian project announced on November 23, 2009, in which TowerJazz is providing know-how, training and turnkey manufacturing solutions.

The company now expects fourth-quarter revenue to be between $98 million and $102 million, which is higher than the previous guidance of $90 million to $94 million, with a mid-range representing a 26% increase from previous quarter revenues and a 29% increase year over year and representing company record revenue.
