API Technologies Closes Nanotechnology Research and Development Subsidiary: Allows Company to Focus Resources and Capital on Profitable Defense Businesses

NEW YORK, NY – (PRNEWSWIRE) – February 22, 2010 – API Technologies Corp. (ATNY.OB) ("API" or the "Company"), a prime contractor in sophisticated electronics, highly engineered systems, secure communications and electronic components and subsystems to the global defense and aerospace industries, today announced that it is closing its nanotechnology research and development subsidiary. Founded in 2000 and acquired by API in 2007, the NanoOpto subsidiary is located in Somerset, New Jersey. The Company expects the shut down process to be completed within the next 90 days and will contribute in excess of $4 million to operating earnings.

“This decision, while difficult, will significantly improve API’s operating results and allow us to deploy our capital and management resources on our expanding profitable defense business,” said Stephen B. Pudles, Chief Executive Officer of API Technologies Corp. “Together with our two recent successful acquisitions, API will now become a dedicated value-added subcontractor to the defense business and will be better able to serve the needs of our blue chip global customers.”
