Dear Valued Customers

Subject: Business Combination between TTM Technologies, Inc. and Meadville Group PCB

I am pleased to inform you that TTM has announced a definitive agreement that will result in the business combination of TTM Technologies, Inc. and the printed circuit board business of Meadville Holdings Limited. This transaction will fulfill a long-stated TTM M&A objective to develop a complementary offering of high volume, low-cost commercial printed circuit board manufacturing capabilities.

Meadville is headquartered in Hong Kong and operates seven facilities in mainland China and one in Hong Kong. It is one of the leading PCB manufacturers in China, posting 2008 revenue of US $669 million. The company focuses on the production of higher technology commercial PCBs, flexible and rigid-flex circuits and chip carrier substrates. You can learn more about Meadville by accessing its website at www.meadvillegroup.com.

The combination of TTM and Meadville will be a transformational event, creating one of the world’s leading PCB products and backplane assembly companies with state of the art production capabilities in both the North America and Asia/Pacific regions. The resulting integrated sales force and manufacturing operations will provide our commercial customers with a true global one-stop solution, capable of cost effectively supporting a broad range of PCB and backplane product technologies throughout the entire product life cycle. Furthermore, by strengthening our ability to compete and grow in commercial markets, this transaction will reinforce TTM’s ability to invest in its technology leadership positions and to continue to grow as the leading supplier of custom aerospace & defense PCB products in North America.

This is very exciting news for TTM, Meadville and our respective customers. The transaction is subject to various regulatory and government approvals, and the approval of both companies’ shareholders. As such, it is currently anticipated that the deal will close during the first quarter of 2010. Until closure, both companies must continue to operate independently. I want to assure you that during this transition period, our customers can count on TTM to remain fully focused on successfully executing to fulfill your product development, production and delivery requirements. In addition, we will endeavor to keep you apprised of progress as we work to close this transaction.

In closing, I want to advise you that TTM and Meadville are conducting a conference call and presentation on November 16, 2009 at 5:00 am PST / 8:00 am EST to provide greater detail about this deal. If you cannot join the call you will be able to access a recorded version for the next seven days. A link will be available on our website at www.ttmtech.com.

Sincerely,

Douglas L. Soder
Executive Vice President
