Innovative Solutions & Support, Inc. Announces First Quarter Fiscal 2009 Financial Results

Revenues Up 123%, Operating Margin of 16%, Earning Per Share of $0.11

Exton, PA. – January 28, 2009 – Innovative Solutions & Support, Inc. (NASDAQ: ISSC) today announced its financial results for the first quarter of fiscal 2009 ending December 31, 2008.

Net revenues for the first quarter of fiscal 2009 were $10.6 million, up 123% from $4.7 million in the first quarter of the previous fiscal year.  The Company reported first quarter fiscal 2009 net income of $1.8 million, or $0.11 per fully diluted share, compared to a fiscal first quarter 2008 net loss of ($4.1 million), or ($0.24) per fully diluted share.

Net income and earnings per share for the quarter reflect the reinstatement of the US research and development tax credit during October, 2008, and the reversal of valuation allowances established in fiscal year 2008 based upon projected, current

year taxable income.  As a result, the effective tax rate for the fiscal first quarter of 2009 was 4%.

Geoffrey Hedrick, Chairman and Chief Executive Officer of Innovative Solutions & Support, Inc., said, “We delivered record Flat Panel Display revenues in the first quarter reflecting the production and shipment of customer orders on-time and on-budget. Strong revenue growth is driving leverage of our fixed manufacturing infrastructure resulting in margins that continue to expand toward our historical performance capabilities.

“We are intently focused on leveraging our leadership in retrofitting aircraft to capitalize on the increasing interest of fleet and other operators in upgrades and repairs.  We have the added benefit of a strong balance sheet to support our strategy to deliver growth in revenues, profitability, and cash flow.”

Business Outlook

For the second quarter fiscal 2009, based upon existing backlog, current production schedules and improving operating efficiency, the Company expects; net revenues $9.5 - $10.5 million; diluted earnings per share $0.06-$0.09; 10% effective tax rate; with positive operating cash flow.
