Meadville Announces PCB Business Combination With

TTM Technologies, Inc.

* * *

To create one of the world’s largest PCB companies

HONG KONG, November 16, 2009 — Meadville Holdings Limited (“Meadville”) (HKSE: 3313.HK), a leading printed circuit board (“PCB”) manufacturer, announced today that it has signed a definitive agreement to sell its PCB business to TTM Technologies, Inc. (Nasdaq: TTMI, “TTM”), North America’s largest PCB manufacturer by revenue. Following the completion of the proposed transaction (expected to complete in the first quarter of 2010), the combined PCB business will be one of the world’s leading PCB business with strong PCB production and R&D capabilities in both North America and the Asia Pacific region with broader market exposure worldwide.

Meadville entered into a conditional stock purchase agreement to sell its PCB business to TTM for a consideration of approximately US$521.3 million (equivalent to approximately HK$4,040.5 million), of which TTM will pay cash of approximately US$114.0 million (equivalent to approximately HK$883.8 million) and issue approximately 36.3 million new TTM shares, representing an aggregate value of approximately US$407.3 million (equivalent to approximately HK$3,156.7 million), based on the US$11.21 (equivalent to approximately HK$86.88) closing price of TTM shares as at November 13, 2009.

TTM is North America’s largest PCB manufacturer and a leading supplier of PCB and backplane assemblies and specializes in the high-end commercial and aerospace / defense markets, including networking and communications infrastructure, computing, industrial and medical markets. Its customers include original equipment manufacturers and international electronic manufacturing services companies. Currently, TTM has eight manufacturing operations, seven of which are in the U.S. and one in the PRC.

Upon completion of the transactions, Meadville’s largest shareholder, Mr. Tang Hsiang Chien (“Mr. HC Tang”) through his company, will own approximately 26.2 million TTM

shares, representing approximately 33.0% of the enlarged issued share capital of TTM. Mr. HC Tang or his representatives will continue to manage the PCB business in Asia, and to provide continuity to the business and stability to the workforce.

On the same day, Meadville has also entered into a conditional sale and purchase agreement to sell its laminate business for a total consideration of approximately HK$2,783.8 million to Top Mix Investments Limited, a company wholly-owned by Mr. HC Tang. Meadville’s laminate business currently owns approximately 22.2% of Guangdong Shengyi Sci. Tech Co., Ltd. (SHSE: 600183), 25.0% of Suzhou Shengyi Sci. Tech. Co., Ltd. and a majority stake of other laminate operations in Hong Kong and China.

Commenting on the proposed PCB transaction, Mr. Tom Tang, Executive Chairman and Group Managing Director of Meadville, said, “The combination of the PCB businesses of Meadville and TTM will create a leading global player in the international PCB industry with a “Global Presence, Local Knowledge” strategy. The proposed transaction enables us to further capture growing worldwide potential by sharpening our market competitiveness and extending our global presence. The joint efforts will further expand the platform of the Meadville PCB business in the growing Asia region while complementing TTM’ existing U.S. footprint in the PCB industry.”

“The combined scale, complementary product capabilities, and market breadth of these two great companies will create significant competitive advantages in the increasingly dynamic PCB industry,” said Mr. Kent Alder, President and CEO of TTM.

The above two transactions are to be approved by the shareholders of Meadville and TTM and completion of the two transactions are conditional on each other. Upon completion of the two transactions and subject to satisfaction of certain closing conditions, Meadville proposes to delist from Hong Kong Stock Exchange and will declare a dividend of approximately HK$3.47 per Meadville share to its shareholders, comprising of cash and TTM shares equivalent to the aggregate amount of the sale proceeds received from the laminate sale and the PCB sale. The said dividend is comprised of approximately HK$1.867 in cash and 0.0185 TTM share for every Meadville share, which represents a premium of approximately 61.4% over the closing price of HK$2.15 per Meadville share as quoted on the last trading date before Meadville’s formal announcement.

Commenting on the two proposed transaction, Ms. Mai Tang, Vice Chairman of Meadville said, “This is an attractive opportunity for all Meadville’s shareholders to realize the value of their shareholding in Meadville and at the same time retain an interest in the PCB business which will be combined with TTM”.

Merrill Lynch (Asia Pacific) Limited acted as exclusive financial advisor to Meadville and UBS AG, Hong Kong Branch acted as the exclusive financial advisor to TTM on the relevant transaction.
