Exhibit 99.1

Innovative Solutions & Support, Inc. Announces Financial Results for
the First Quarter of Fiscal Year 2008

Exton, PA — January 30, 2008 — Innovative Solutions & Support, Inc. (NASDAQ: ISSC) (the “Company”) today announced results for the first quarter of fiscal year 2008 ended December 31, 2007.

Sales in the first quarter of fiscal 2008 were $4.7 million, compared to $3.4 million in the first quarter of fiscal 2007.  Sales in the current quarter included the shipment of 58 Flat Panel Display Systems to Eclipse Aviation in the month of December 2007.

The Company reported a net loss of $(4.1) million, or $(0.24) per fully diluted share in the first quarter of fiscal 2008 as compared to a net loss of $(1.1) million, or $(0.07) per fully diluted share in the first quarter of fiscal 2007.  The loss in this year’s first quarter is principally the result of $3.5 million of legal expenses incurred in connection with the successful trade secret case against Kollsman Inc. (“Kollsman”) and related parties and low gross margins related to start up production costs under the Eclipse program.

Related to the trade secret case, on December 18, 2007 the court entered a temporary injunction aimed at preventing further use of IS&S’s trade secret and proprietary information.  The judge presiding over the case will hear IS&S’s claims for a permanent injunction as well as punitive and exemplary damages and attorneys’ fees against Kollsman and the other defendants in a hearing currently scheduled for March, 2008.

Ray Wilson, Chief Executive Officer of Innovative Solutions and Support, Inc., commented, “I am encouraged by the progress achieved as we enter our new fiscal year.  In December, our Flat Panel Display System was officially certified as part of the Avio NG Total Aircraft Integration System.  This is the fastest certification of a new OEM aircraft avionics system, and we are excited to have partnered with Eclipse Aviation in this landmark achievement.  With certification complete, Eclipse FPD production will be

consistent with their delivery schedules.  We also expect to see demand to retrofit the approximately 100 Eclipse VLJs that were originally manufactured before our FPD systems were available.  Production and shipments are also ramping up on several other existing contracts this quarter, including FedEx and American Airlines, and we expect several others will follow over the balance of the year.”

As of December 31, 2007, backlog was approximately $70 million, of which approximately $61 million was for Flat Panel Display Systems.  At December 31, 2006, Flat Panel Display System backlog was $23.5 million.  Except for orders currently in production and with definitive delivery requirements over roughly the next eight weeks, backlog figures do not include the potential value of the Eclipse Agreement.

Please refer to the accompanying schedules highlighting the Statement of Operations and Balance Sheet.  For information on our backlog, please refer to the investor presentation attached as Exhibit 99.1 to our Form 8-K filed with the SEC on January 10, 2008.

The Company will host a conference call tomorrow morning, Thursday, January 31, 2008 at 9:30 am local time (EST) to discuss these results as well as our business outlook. Please call in to participate at (973) 582-2703.
