PROXY STATEMENT

FOR

SPECIAL MEETING OF STOCKHOLDERS

to be held on February 15, 2007

The date of this Supplement is February 8, 2007.

On January 29, 2007, Acquicor Technology Inc. (" Acquicor ") filed a definitive proxy statement (the " Proxy Statement ") relating to the proposed merger of its wholly-owned subsidiary with and into Jazz Semiconductor, Inc. (" Jazz "). Acquicor has set February 15, 2007 as the date for the Special Meeting of Stockholders at which the acquisition of Jazz and certain other proposals will be voted upon. The meeting will be held at 1:00 PM at the offices of Latham & Watkins LLP in Costa Mesa, California. As previously disclosed, the record date for determining Acquicor stockholders entitled to vote at the Special Meeting of Stockholders has been fixed as the close of business on January 16, 2007. This Supplement supplements and amends the Proxy Statement in order to add information regarding an amendment to the Company’s 2006 Equity Incentive Plan.

On February 8, 2007, Acquicor Technology Inc. announced that its Board of Directors has approved an amendment to its 2006 Equity Incentive Plan, to reduce the annual increase in the number of shares subject to the plan from a maximum of 700,000 to 250,000. The impact of this change is to reduce the total number of shares that could potentially be issued under the plan, thereby reducing the potential dilutive impact of the plan on other stockholders. One of the proposals being voted on at the Special Meeting of Stockholders is the approval of 2006 Equity Incentive Plan. Acquicor’s board of directors recommends that you vote, or give instruction to vote, " FOR " the adoption of 2006 Equity Incentive Plan as so amended.
