NEENAH, WI – Plexus Corp. reported first-quarter revenue of $381 million, in line with previous estimates. The company warned that previously expected military program ramps were not materializing as expected.

Plexus revised its full fiscal year revenue growth target to 8% to 12% over fiscal 2006, from 15 to 18% previously.

In a press release, president and CEO Dean Foate said, “As we look to Q2, we are experiencing softness with a number of customers across all of our market sectors. We continue to have poor visibility into the decision-making process concerning potential follow-on orders for a large defense contract.

“We expect revenue growth to resume in the second half of our fiscal year,” he said.

The firm expects a new facility in Malaysia to be operational in the March quarter, and an expansion in China to be completed by September. It is also upgrading manufacturing equipment in Mexico and at some sites in the U.S.
