Jazz US Holdings

Jazz US Holdings, Inc. is based in Newport Beach, California and through its direct and indirect wholly-owned subsidiaries Jazz Semiconductor, Inc. and Newport Fab, LLC, is an independent semiconductor foundry focused on specialty process technologies for the manufacture of analog intensive mixed-signal semiconductor devices. In November 2015, as part of a corporate restructure, Jazz Technologies, Inc. transferred all of its liabilities and all of its assets, including its ownership of all of the shares of Jazz Semiconductor, Inc., to Jazz US Holdings, Inc., a newly established company registered under the laws of Delaware and fully owned by Jazz Technologies, Inc. (now known as Tower US Holdings, Inc.) which is wholly owned by Tower. The transaction established Jazz US Holdings as an intermediate holding company, holding all of the shares of Jazz Semiconductor. As a result of the restructure which involved companies under common control, the financial statements of Jazz US Holdings, Inc. and subsidiaries are presented as if the restructure had occurred on the first day of earliest year presented. In December 2015, pursuant to a supplemental indenture entered into among Tower US Holdings, Inc., Jazz US Holdings, Inc. and the trustee for the notes due December 2018, Jazz US Holdings, Inc. replaced Jazz Technologies, Inc. as obligor under these notes.
