New Initiative

TowerJazz announces signing a binding MOU with a leading Indian infrastructure conglomerate, to build and operate a 300mm facility in India. This will enable the company a roadmap to long term 300mm wafer size, 90nm analog technology and companion chips in deep submicron technologies (65-45nm). The Company presented to empowered government committee as 3-way consortia with a leading Indian infrastructure conglomerate, TowerJazz and a worldwide leading technology provider. The Company believes that we are in the best position, as (1) the consortia is very strong and (2) TowerJazz has an impeccable reputation in India based on a previous successful government fab project win and execution. However, the Company cannot predict the outcome of government selection, and hence neither has nor can give assurance it will win this bid.

CEO and Chairman Perspective

Russell Ellwanger, Chief Executive Officer, commented: “From both strategic and business standpoints, 2011 was a very strong year in performance and a catalyst for the future. Fueled by a long term business relationship with a new customer, Micron Technologies, we were able to achieve 20% year over year growth, multiples above our peer group. In addition, we doubled our wafer capacity as compared to 2010, in a most cost effective manner. Driven by performance and an ability to provide capacity commitments, we have strong engagements with market leaders in all of our business segments. We are operationally preparing for a strong second half, having received such indications from lead customers.”

Mr. Ellwanger added, “We have a most capable and impassioned worldwide employee base, who are excited with the opportunities in front of us, as we implement our 2012 mantra ‘the pursuit of excellence’.”

Mr. Amir Elstein, Chairman of the Board, in commenting on the corporate performance and the future, stated: “In only a few years, the Company has cemented a substantial lead as the specialty foundry market leader, with strategic tier one customers in high growth, high margin analog segments. The recently signed India MOU is a tremendous opportunity for TowerJazz to utilize its manufacturing knowhow and technical expertise to gain a low cost entrance into an emerging market at a 300mm wafer size level. Should this proposal not be accepted, we remain active in pursuing such models where we add benefit to our partners and customers through our expertise and execution and benefit to the shareholders through profitable upside growth.”
