TTM TECHNOLOGIES, INC. ANNOUNCES CLOSURE
OF HAYWARD AND LOS ANGELES FACILITIES

SANTA ANA, CA – September 1, 2009 – TTM Technologies, Inc. (Nasdaq: TTMI) today announced that it will close its Hayward, California and Los Angeles, California facilities due to continued weak demand in North America for commercial printed circuit boards and backplane products.

“This is a very unfortunate but necessary decision based on the prospects of long-term weaker demand for these products,” said Kent Alder, CEO of TTM Technologies. “We will do all that we can to assist the employees impacted by this decision through this difficult process.”

The company expects to record between $11 million and $14 million in separation, asset impairment and disposal costs related to this restructuring, primarily in the third quarter of 2009. The actual expense will vary, depending on utilization of inventory and transfer of fixed assets. In addition to transferring assets to other sites, the company plans to sell some of the property, plant and equipment. As a result of today’s actions, the company expects to achieve annual cost savings of approximately $14 million.

Excluding asset impairment charges and closure costs, the company remains on track to achieve its earnings and revenue guidance for the third quarter with revenue in a range of $134 million to $142 million and GAAP earnings in a range from $0.09 to $0.15 per diluted share.

TTM will transfer PCB production from the Los Angeles facility to other company sites in California, Utah and Wisconsin, providing an uninterrupted supply of PCBs to customers of the Los Angeles facility.

Backplane assembly services provided by the Hayward plant will be transferred to the company’s other backplane assembly plants in Shanghai, China and Stafford Springs, Connecticut depending on the nature of the business. The company will continue to support Hayward’s customers with local sales and technical service teams.

The Los Angeles operation, which primarily produces commercial printed circuit boards, employs 263 full-time employees. The Hayward operation, which produces commercial backplane assemblies and system integration products, employs 84 full-time employees. The combined reduction in force represents approximately 11 percent of TTM’s work force. TTM will offer separation and other benefits to the affected employees.

“The actions we are announcing today are the result of a methodical and strategic evaluation process regarding our manufacturing capacity and cost structure in the context of ongoing demand challenges,” Alder said. “These actions position TTM with a more cost effective manufacturing solution for today’s market. Importantly, this restructuring will allow us to improve capacity utilization and to maintain appropriate upside capacity to grow with our customers as the market eventually recovers.”
