Exhibit 99.1

Innovative Solutions & Support, Inc. Announces Financial Results for the 1st Quarter Ended December 31, 2006.

Exton, PA.—(BUSINESS WIRE)—January 30, 2007—Innovative Solutions & Support, Inc. (NASDAQ:ISSC-news) today announced results for the 1st quarter ended December 31, 2006.

Sales in the first quarter of FY 2007 were $3.4 million. This compared with sales of $5.4 million in the first quarter of FY 2006.

Gross margin percentages were 41% in this year’s first quarter and 50% in last year’s first quarter. The lower margin this year was the result of lower sales in the current quarter as opposed to last year.

In this year’s first quarter, the Company incurred a $(1.1) million net loss or $(0.07) per fully diluted share as opposed to a break even position in the first quarter of FY 2006.

The Company continued to invest heavily in Research and Development (R&D). In the first quarter R&D spending amounted to $1.3 million or 39% of sales. Last year R&D spending in the first quarter amounted to $1.5 million or 28% of sales.

Please refer to the accompanying schedules highlighting our Statement of Operations and Balance Sheet.

New Flat Panel orders in the quarter ended December 31, 2006 were $6.7 million. Other new business orders were $1.0 million in the quarter. As a result, a $32.3 million backlog as of December 31, 2006 was achieved. This was an increase of $14.1 million or 77% over the December 31, 2005 backlog of $18.2 million. The Flat Panel portion of backlog was $23.5 million this year and almost doubled from the $12.1 million recorded at December 31, 2005.

Mr. Ptakowski, President of Innovative Solutions and Support, Inc., commented “Our financial performance in the quarter was expected as we continue to put in place the foundation to return to profitability and growth with our Flat Panel Display Systems. We continue to be encouraged by the significant acceptance of our Flat Panel Display Systems and attainment of critical milestones. Last year, we announced critical marketing partnerships and recorded new orders totaling $18.9 million from a diverse customer base and broad program mix. In this year’s first quarter we have continued our ability to attract critical partnerships and announced an agreement with Cessna Aircraft to provide Flat Panel Display Systems on legacy Cessna aircraft. As a result, our backlog contains awards that the Company views as momentum orders because they establish current standards of excellence in older airplanes and we believe that entire fleets will become candidates for retrofit in subsequent periods.”

The company will host a conference call tomorrow morning, January 31, 2007 at 9:30 am local time (EST) to discuss these results as well as our business outlook. Please call in to participate at (877) 675-8475. The conference call ID# is: 7012741.
