Tessera Receives Initial $20 Million Payment Resulting from Amkor Arbitration

Tessera Technologies, Inc.

(the “Company”) announced today that Tessera, Inc. has received an initial payment of approximately $20 million from Amkor Technology, Inc. related to the interim award the International Court of Arbitration of the International Chamber of Commerce (ICC) issued on July 6, 2012, in favor of Tessera, Inc. in its dispute with Amkor. “As previously announced, we intend to seek an amount in excess of $125 million in connection with the ICC's interim award,” stated Richard Chernicoff, president of Tessera Intellectual Property Corp. “We believe that litigation tactics are driving Amkor's decision to only pay this partial amount at this time, and we will continue to vigorously pursue our right to recover the full amount due.”
