EPS GROWTH OF 264% TO $0.51/SHARE FOR THE THREE MONTHS ENDED DECEMBER 31, 2004.

Exton, PA.--(BUSINESS WIRE)--January 19, 2005--Innovative Solutions & Support,
Inc. (NASDAQ:ISSC-news) today announced the following record results for the 1st
quarter ended December 31, 2004:

         Q1 FY 2005
         o Sales              up 123% to a record $19.0 million.
         o Net income         up 285% to a record $6.2 million.
         o EPS, diluted       up 264% to a record $0.51 a share
         o Backlog            up 39% to a record $36.2 million
         o Cash Flow          Record $7.5 million


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

A Company spokesperson commented: "In the 1st quarter we experienced strong
demand for our Air Data equipment as compliance for Domestic Reduced Vertical
Separation Minimum (DRVSM) approaches its effective date of January 20, 2005. We
also expect demand for our Air Data equipment beyond the compliance date as a
result of delayed DRVSM installations. According to a January 10, 2005 article
in Aviation Week & Space Technology magazine, 'only 6,100 business jets or 62%
of the eligible fleet have been outfitted'. Beyond DRVSM, we expect on going
demand for the replacement of aged, obsolete and troublesome Air Data
equipment."

The General Aviation market (business jets) currently represents the largest
demand for DRVSM solutions. In this market, Innovative Solutions is a leading
supplier of Air Data equipment with certified solutions for Falcon, Cessna
Citation, Learjet, Gulfstream, Sabreliner, Raytheon King Air, Beechjet,
Westwind, Hawker and Challenger business aircraft. The Company also has
certified solutions for a wide variety of commercial air transport aircraft
including DC-8's, DC-9's, B-707's, B-727's and B-737's, and Military aircraft
including A-10's, KC-135's, RC-135's and C-130's.

At December 31, 2004 the Company's backlog reached a record $36.2 million. This
reflects a 39% increase from the December 31, 2003 backlog of $26 million.

The company will host a conference call tomorrow morning, January 20, 2005 at
10:00 am local time (EST) to discuss these results and our business outlook.
Please call in to participate at (888) 792-8459. Also, our web site
