REDMOND, WA - May 1, 2003 - TTM Technologies, Inc. (Nasdaq: TTMI), a leading manufacturer of time-critical, technologically advanced printed circuit boards, today reported results for the first quarter ended March 31, 2003.

First-Quarter Results
First quarter 2003 revenue increased 67 percent to $39.6 million, compared to $23.7 million for the first quarter of 2002. The increase was due to the acquisition of Advanced Circuits, Inc. (ACI) in the fourth quarter of 2002.

For the first quarter of 2003, quick-turn business decreased to 28 percent of total revenues, compared to 44 percent for the first quarter of 2002, because of the addition of ACI, with its focus on high technology, standard lead time PCBs.

Gross profit increased 74 percent to $4.5 million, as gross margins increased to 11.4 percent in the first quarter of 2003, compared to 10.9 percent for the same period in 2002.

General and administrative expenses increased from $825,000 to $2.8 million. This increase was due to the inclusion of ACI in TTM's results, higher bad debt expense and directors and officers insurance expense, and the cost of integrating ACI into its operations. TTM also incurred a restructuring charge associated with the previously announced headcount reductions at its Redmond, Washington facility.

TTM had an operating loss of $1.3 million for the first quarter of 2003, compared to an operating loss of $185,000 for the first quarter of 2002.

For the first quarter of 2003, TTM reported a net loss of $150,000, or breakeven on a per share basis, including an extraordinary gain of $824,000, or $0.02 per share, associated with the acquisition of ACI. The net loss before extraordinary item for the first quarter of 2003 was $974,000, or ($0.02) per diluted share. This compared with a net loss of $278,000, or ($0.01) per diluted share, for the first quarter of 2002.

Earnings before interest, taxes, depreciation and amortization (EBITDA) for the first quarter of 2003 were $897,000, down from $2.4 million for the same period in 2002.

"We are encouraged by the results of our recent ACI acquisition," said Kent Alder, President and CEO of TTM Technologies. "The integration has progressed well. ACI generated positive cash flow and its performance exceeded our expectations for the quarter. In addition, ACI is creating cross-selling opportunities with our existing operations that should enable us to gain market share. However, we continue to battle the weak business conditions in the electronics industry, and we experienced the typical first-quarter, seasonal weakness in our quick-turn segment."

Cost Cutting Update
The production realignment and the subsequent closure of the Burlington, Washington facility in 2002 has generated substantial cost savings. In addition, TTM implemented cost-cutting measures with a reduction in force at its Redmond facility in the first quarter, which should yield additional cost savings in the second quarter.

Financial Strength
"Our balance sheet continues to strengthen," said Alder. At the end of the first quarter, TTM had cash of $26.1 million and debt of $10 million, compared with cash of $18.9 million and debt of $10 million at year-end 2002. TTM's cash increased due to a tax refund of $5.7 million and positive cash flow from operations. In addition, the company continued to maintain a revolving credit facility of $25 million, which was undrawn at the end of the quarter.

Outlook
With the challenging global events from Iraq to SARS, TTM does not see a recovery in the electronics market in the near term. However, the company anticipates growth in the form of market share gains.

For the second quarter of 2003, TTM anticipates revenues ranging from $39 to $41 million and breakeven earnings per share.

"Among our major U.S. competitors, we believe we are the low-cost producer with the benefit of a very strong balance sheet," concluded Alder. "While we have aggressively cut costs to maximize performance during the downturn, we continue to expand our product offerings, grow our customer base, and invest in our time and technology strategy."
