Microsemi Marks 20 Years in Ireland and Names Ennis as its European Headquarters

Microsemi Corporation, a leading provider of semiconductor solutions differentiated by power, security, reliability and performance, today officially named its Ennis, Ireland facility as its European headquarters.

The announcement represents a significant endorsement of the work of the Ennis facility and its contribution to the wider Microsemi global network. Ennis has been a world class facility and a key contributor in the manufacturing processes of the company’s high reliability products, and is well-poised to contribute to Microsemi Corporation’s planned expansion and growth strategy. The Ennis facility has recruited an additional 50 staff so far in 2012, taking headcount at the site to approximately 300. The continued availability of skilled staff in the region will assist the Ennis facility to develop new products and grow key research and development functions.

The announcement was made at a celebration commemorating the company’s 20-year anniversary in Ireland, which was attended by several senior company executives including James J. Peterson, Microsemi’s president and chief executive officer. In conjunction with naming Ennis its European headquarters, Peterson announced the inaugural Microsemi Scholarship in Engineering at the prestigious University of Limerick. In addition, the company funded a high-profile science and aerospace engineering programme in St. Flannan’s school in Ennis.

“We have been impressed at Microsemi with the calibre of engineering graduates in Ireland and we are confident about the future of the skill base in Ireland, hence our decision to make Ennis our European headquarters,” said Peterson. “Naming Ennis our European headquarters is a testament to the hard work and talent of the many employees who have built this facility into a world-class manufacturing, sales and engineering center and gateway for our European operations.”

“As part of our commitment to Ireland, we are proud to sponsor an engineering scholarship at the University of Limerick and a programme at St. Flannan’s to cultivate interest in science and innovation,” continued Peterson. Microsemi works closely with the IDA Ireland, which is responsible for attracting and developing overseas investment in Ireland. According to Peterson, support from IDA Ireland was a key factor in the company’s decision to invest in the region.

“Microsemi is a growing company with ambitious plans and Ennis is well-positioned to contribute to this growth,” said Barry O’Leary, chief executive officer of IDA. “The contribution of the company to the local economy and community is highly significant, and it is gratifying to see the partnership strengthening with the announcement that Ennis is to become its European headquarters.”
