API Technologies Reports Fiscal Fourth Quarter and Full Year 2011 Results

ORLANDO, FL – August 26, 2011 – API Technologies Corp. (NASDAQ:ATNY) (“API” or the “Company”), a provider of electronic systems, subsystems, RF, and secure solutions for the defense, aerospace, and commercial industries, today announced results for the fiscal fourth quarter and twelve months ended May 31, 2011. The fourth quarter results reflect the inclusion of three months of SenDEC Corp., acquired January 24, 2011, but do not include any results of Spectrum Control, acquired after the fiscal year end, on June 1, 2011.

Recent Corporate Highlights

“We are well-positioned with both programs and customers who will continue to demand our high technology products and services in the years to come,” said Bel Lazar, President and Chief Operating Officer of API Technologies. “The new API Technologies, incorporating API Defense, SenDEC, and Spectrum Control, brings together scale, momentum, and a strong portfolio of sole-sourced and proprietary electronic products and solutions to better serve the defense, aerospace, and industrial markets. Moreover, with pro-forma annualized revenues in excess of $350 million, we are implementing strategies to grow our business while also expanding margins and cash flow. We have already identified and begun implementation of over $10 million in anticipated annualized cost savings and synergies, while at the same time positioning API Technologies for a continuous path of improvement and increased shareholder value.”

Financial Results for the Fourth Quarter Ended May 31, 2011

API Technologies reported revenue of $28.7 million for the fiscal fourth quarter of 2011, as compared to $30.1 million for the same period in fiscal 2010, primarily due to the completion of a major program at the Company’s Windber operations during the third quarter of fiscal 2011, partially offset by additional revenue from the acquisition of SenDEC. Gross profit was $2.2 million compared to $7.9 million in the previous year’s fiscal fourth quarter; gross margin, as a percent of sales, decreased to 7.5% in the period ended May 31, 2011, versus 26.2% in the comparable period in the prior year, reflecting a change in product mix due to the inclusion of SenDEC and the impact of the transfer of certain operations to Windber.

The Company posted a net loss of $14.7 million for the fiscal fourth quarter of 2011, as compared to net income of $0.3 million in the fiscal fourth quarter of 2010. The quarter ended May 31, 2011 includes $10 million in charges related to restructuring expenses and transaction-related costs.

Financial Highlights for the Twelve Months Ended May 31, 2011

Revenue for the twelve months ended May 31, 2011 was $108.3 million, an increase of 58% versus $68.6 million reported in the prior fiscal year period. This primarily reflects the inclusion of approximately four months of SenDEC revenues and increased sales related to a full year of operations from the Company’s Windber operations, compared to approximately four months in the prior fiscal year following the asset acquisition in January, 2010. Gross profit increased to $20.2 million from $17.3 million in fiscal 2010, while gross margin, as a percent of sales, declined to 18.6% from 25.3% in the fiscal year ended May 31, 2010. The lower gross margin reflects a change in product mix and the impact of the transfer of certain operations to Windber.

The Company posted a net loss of $26.2 million for the twelve months ended May 31, 2011 versus a net loss of $9.0 million in the prior fiscal year. The 2011 fiscal year includes $18.8 million in charges related to restructuring expenses and transaction-related costs.
