On December 6, 2012, TTM Technologies, Inc. (the “Company”) appointed Thomas T. Edman as President of the Company, effective January 7, 2013. Mr. Edman will report to Kent Alder, the Company’s Chief Executive Officer.

Mr. Edman joins the Company from Applied Materials, Inc., where he most recently served as Group Vice President and General Manager of the AKT Display Group. Prior to joining Applied Materials, Mr. Edman was with Applied Films Corporation from 1996 to 2006, and served as President and Chief Executive Officer of Applied Films from 1998 to 2006. From 1993 to 1996, he was General Manager of the High Performance Materials Division of Marubeni Specialty Chemicals Inc., a subsidiary of a major Japanese trading corporation. Mr. Edman serves on the Governing Board of the FlexTech Alliance, an electronics supply chain association. He holds a Bachelor of Arts degree in East Asian Studies from Yale University and a Master’s degree in Business Administration from the Wharton School of Business at the University of Pennsylvania. Mr. Edman will continue to serve as a director of the Company, in which capacity he has served since September 2004, but will no longer serve as a member of the Compensation Committee (the “Committee”) of the Board of Directors.

Mr. Edman and the Company have not entered into an employment agreement. There was no arrangement or understanding pursuant to which Mr. Edman was elected as President of the Company, and since the beginning of the Company’s last fiscal year, there have been no related party transactions between Mr. Edman and the Company that are reportable pursuant to Item 404(a) of Regulation S-K. Mr. Edman is not related to any executive officer or director of the Company.

Mr. Edman will receive a base salary of $550,000, which may be increased from time to time at the discretion of the Committee. On the effective date of his appointment as President, Mr. Edman will receive an initial grant of restricted stock units with a value of $405,000 based upon the 6-month trailing average of the closing trading price of the Company’s common stock. These restricted stock units will vest in three equal annual installments. Mr. Edman will be eligible to participate in the Company’s previously disclosed annual incentive compensation plan with a target amount equal to 85% of his annual base salary subject to the satisfaction of performance criteria to be established by the Committee. In addition, consistent with the Company’s previously disclosed performance-based restricted stock units (“PRUs”) program, Mr. Edman will receive, upon approval of the Committee in accordance with its customary annual compensation cycle, PRUs with a target value of $495,000 based upon the 6-month trailing average of the closing trading price of the Company’s common stock. Consistent with the PRU program, these PRUs will be subject to a three-year performance period. The number of shares of the Company’s common stock released at the end of the performance period will be based upon the satisfaction of performance targets to be established by the Committee and an overall total stock return “modifier.”

On December 6, 2012, the Company issued a press release announcing the appointment of Mr. Edman as President of the Company. A copy of this press release is attached hereto as Exhibit 99.1 and is hereby incorporated by reference in this Item 5.02.
