Innovative Solutions & Support, Inc. Announces First Quarter Fiscal 2010 Financial Results

Exton, PA. – January 27, 2010 – Innovative Solutions & Support, Inc. (NASDAQ: ISSC) today announced its financial results for the first quarter of fiscal 2010 ending December 31, 2009.

Net revenues for the first quarter of fiscal 2010 were $4.6 million compared to $10.6 million in the first quarter of fiscal 2009. The Company reported a first quarter fiscal 2010 net loss of ($1.1) million, or ($0.07) per fully diluted share, compared to net income of $1.8 million, or $0.11 per fully diluted share, in the same quarter a year ago.

Geoffrey Hedrick, Chairman and Chief Executive Officer of Innovative Solutions & Support, Inc., said, “As anticipated, we continue to work our way through the slowdown in the aviation industry that first began to impact our results in the second half of fiscal 2009. In the near term, lower production volumes brought about by economic uncertainty and more conservative customer order patterns are hurting both the top and bottom line. Fortunately, we have built a strong balance sheet and

customer relationships that enable us to take a longer term view. By preserving our product development resource and efficient manufacturing infrastructure, we are prepared for the expected increase in demand later this year that will be driven by our customer’s planned delivery schedules for existing and new orders. We are also developing products for additional platforms, to enhance our product functionality and to accelerate the expansion of the immediately addressable market. At the very core, we are making significant strides improving our fundamental competitive position through continual innovation and by rapidly adapting to evolving market demands.”

At December 31, 2009, the Company had $36.5 million of cash on hand, no long term-debt, and a backlog of $34.3 million.

Roman Ptakowski, President of the Company added, “The economic turmoil that has forced many operators to delay critical improvements to the safety, reliability and efficiency of their aircraft has been both disappointing and frustrating. This has not deterred us from aggressively pursuing our strategy of introducing new products and improving the performance of our Flat Panel Display systems to broaden and deepen our market penetration. As the market recovers, we will be well positioned to capitalize on demand from the commercial air transport, military and general aviation markets for economical solutions to their need for improved aircraft performance.”

Business Outlook

While the economic uncertainty that deferred customer procurements beginning with the second half of fiscal year 2009 has not abated, our new proposal activity reaffirms the guarded optimism for the second half of fiscal 2010 as previously addressed.

The Company will be hosting a conference call January 28, 2010 at 10:00 a.m. EST time to discuss these results and its business outlook.
