COSTA MESA, CA -- TTM Technologies reported net profits of $7.7 million for the third quarter, up from a loss of $7.7 million from a year ago.

The printed circuit board maker posted revenue of $345.3 million in the period ended Sept. 29, up 2% from last year.

TTM guided for fourth-quarter sales of $370 million to $390 million for the fiscal fourth quarter.

 "We experienced solid demand across all of our end-markets, led by a strong revenue ramp in cellular phones and better than expected sales in our networking/communications end market," said Tom Edman, CEO. "Our operating margins short of goal due primarily to an unanticipated five day power outage at our advanced technology facility in Asia Pacific, which interrupted our ramp for new products and contributed to our yield shortfall early in the quarter. By the end of the quarter, our productivity and yield levels were back on plan. We anticipate continued improvement in yields and operating performance in the fourth quarter."

Edman said the company's definitive agreement to acquire Viasystems, announced Sept. 22, has been well received. TTM expects the acquisition to help diversify its business and reduce the impact of seasonality inherent in the cellular phone end-market.
