Microsemi Keeping Irish Plant

Microsemi Corp., the Irvine-based maker of chips that power satellites, military aircraft, medical equipment and other things, has opted not to close an Ireland plant previously marked for job cuts.

The company decided to keep open its plant in Ennis in western Ireland to meet increased demand from its defense and aerospace customers, Microsemi said in a filing Wednesday with the Securities and Exchange Commission.

Defense and aerospace makes up about half of Microsemi’s $370 million in yearly sales. The Ennis plant now generates less than 5% of Microsemi’s yearly sales. It spans 62,500 square feet and has about 60 workers.

Earlier, Microsemi said it planned to close the Irish plant as part of a three-phase cost cutting program.

The company announced the cuts in spring 2005. It planned to close and sell off the Ennis plant and about eight others for a yearly savings of about $10 million.
