API Technologies Reports Results for the Fiscal First Quarter

Ended February 29, 2012

ORLANDO, FL – April 9, 2012 – API Technologies Corp. (NASDAQ:ATNY) (“API”, “API Technologies”, 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 first quarter ended February 29, 2012.

“API Technologies continues to make solid progress improving its competitive position and long-term growth outlook,” said Bel Lazar, President and Chief Operating Officer of API Technologies. “We are very pleased with the Company’s performance, both from the top line and adjusted EBITDA performances. We are making significant progress with business integration and cost-cutting initiatives and we remain on track to achieve 20% adjusted EBITDA margins in the quarters to come. Moreover, we recently announced two exciting, strategic acquisitions – C-MAC and RTI – which will enhance our technology portfolio and market penetration.”

“We are very pleased with the acquisitions of both C-MAC and RTI and believe they will continue our strategy of building API Technologies into a dominant supplier of RF/Microwave and microelectronics solutions for high-reliability applications,” added Brian Kahn, Chairman and Chief Executive Officer. “With the closing of these acquisitions, we have added additional capabilities that our existing customer base previously sourced elsewhere, and we have added additional customers, which open new channels to our worldwide sales teams.”

“Subsequent to the end of our fiscal first quarter and taking into account the recent acquisitions, we amended our credit agreement to increase the size of API’s term loan by $16 million to a total of $184.7 million along with access to additional capital for opportunistic developments. Furthermore, the amended credit agreement allowed us to reset the financial covenants to appropriate levels given recent acquisitions and our expanded business forecasts without pinpointing a timeframe for CREW DTI contribution.”

Results for the Quarter Ended February 29, 2012

API Technologies reported revenue of $70.7 million for the quarter ended February 29, 2012 compared to $24.6 million for the same period in the prior year, primarily due to the acquisitions of Spectrum Control and SenDEC. Gross profit was $17.6 million compared to $4.6 million in the previous year’s quarter; gross margin was 24.9% for the period, versus 18.9% in the comparable quarter last year. Adjusted EBITDA was $10.8 million for the quarter compared to virtually zero for the three months ended February 28, 2011.

API Technologies posted net income of $0.8 million for the quarter ended February 29, 2012 compared to a net loss of $10.5 million for this period in 2011. At the end of the quarter, the Company had $14.7 million of cash and cash equivalents and $166.9 million of debt obligations, net of a $3.6 million discount on term loan.

Non-GAAP Financial Information

In this press release, API has provided a non-GAAP financial measure for Adjusted EBITDA (Earnings before interest, taxes, depreciation and amortization), excluding discontinued operations, restructuring charges, acquisition charges, stock-based compensation expenses, amortization of note discounts and deferred financing costs, foreign exchange losses, and certain other adjustments. Management believes the supplemental non-GAAP presentations provide investors an additional analytical tool for understanding the Company’s financial performance by excluding the impact of items which may obscure trends in the core operating performance of the business. These are not recognized measures under US GAAP, do not have a standardized meaning, and are unlikely to be comparable to similar measures used by other companies. Accordingly, investors are cautioned that these non-GAAP measures should not be construed as an alternative to net earnings or loss determined in accordance with GAAP as an indicator of the financial performance of the Company or as a measure of the Company’s liquidity and cash flows. We expect our financial statements to continue to be affected by items similar to those excluded in the non-GAAP adjustments described above, and exclusion of these items from our non-GAAP financial measures should not be construed as an inference that all such costs are unusual or infrequent.

All forward-looking statements are subject to certain risks, uncertainties and assumptions which may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements. These risks and uncertainties include but are not limited to, general economic and business conditions, government regulations, our ability to integrate and consolidate our operations, our ability to expand our operations in both new and existing markets, and the effect of growth on our infrastructure. Should one or more of these risks or uncertainties materialize, or should the assumptions prove incorrect, actual results may vary in material aspects from those currently anticipated. The forward-looking statements in this news release should be read in conjunction with the more detailed descriptions of the above factors located in our Transition Report on Form 10-K under Part I, Item 1A “Risk Factors” as well as those additional factors we may describe from time to time in other filings with the Securities and Exchange Commission.

We undertake no duty to update any forward-looking statement to conform the statement to actual results or changes in the Company’s expectations.
