Integral Systems Announces Record Financial Results

for the First Quarter of Fiscal Year 2008

Management raises EPS outlook for the

Fiscal year to $1.48 - $1.50

Lanham, Md., February 4, 2008 — Integral Systems, Inc. (NASDAQ-ISYS) (“Company”) today reported financial results for the first quarter of fiscal 2008. Revenue for the quarter was $37.3 million, up $9.9 million or 36% from the first quarter of fiscal 2007. First quarter operating income was $8.3 million compared to $2.9 million for the first quarter of last fiscal year, and net income was $7.0 million ($0.75 per diluted share) compared to $2.1 million ($0.19 per diluted share) for the first quarter of fiscal 2007.

The first quarter results include two large non-routine transactions that have a significant impact on the Company’s results. Revenue for the Government Ground Systems segment includes $2.4 million of license revenue for the newly awarded GPS OCX (Next Generation Control Segment) contract. The Company was able to deliver these licenses to the customer during the first quarter as a result of favorable contract terms that included up front delivery of the licenses under the contract. Additionally, the Company recorded a $1.6 million tax credit for tax deductible research and development expenditures that were incurred in prior years and it has filed amended tax returns. Excluding the impact of these two significant events, the Company’s earnings per share on a fully-diluted basis would have been $0.42 for the quarter.

The increase in revenue, operating income, and net income in the first quarter of fiscal year 2008 compared to the corresponding period in 2007 is attributable to increases in all of the Company’s operating segments. The Government Ground Systems segment revenue grew 11%, excluding the acceleration of the GPS OCX license revenue, over the same period last year and 27% in total. Higher revenue from national and civilian programs accounted for the 11% increase. The Commercial Ground Systems segment revenue grew 27% in fiscal 2008, primarily attributed to increased shipments to customers from the Company’s SAT subsidiary and new work awarded in 2007. The Space Communication Systems segment revenue grew 35% in fiscal 2008 due to new RT Logic contracts and higher product shipments from the Lumistar subsidiary.

“We are very pleased with our strong start for fiscal 2008. We had some very positive non-recurring financial events in the first quarter, and all three of our operating groups started out of the gate better than expected,” commented Alan Baldwin, chief executive officer. “We are executing on our growth strategy and are experiencing positive increases in backlog and higher product demand for our subsidiaries.”

The $2.4 million of license revenue generated from the GPS OCX contract represents acceleration into the first quarter of the entire GPS OCX license revenue previously anticipated by the Company to have been recognized throughout the entire fiscal year. Therefore, while the first quarter reflects this very positive result, it does not have an impact on total year revenue and earnings projections. Operating income is expected to be slightly higher in 2008 than initial guidance due to higher demand for products and services, particularly with the Air Force and national programs, partially offset by higher costs for investments in R&D efforts and infrastructure developments. Income tax expense is expected to be significantly lower in 2008 on a percentage basis due to recovery of R&D tax credits from prior years. As a result of all of these factors, earnings are now expected to be in the range of $1.48 - $1.50 on a per share basis for fiscal 2008.

Mr. Baldwin and Mr. Bambarger, the Company’s CEO and CFO, respectively, will host a conference call today, February 4, 2008 at 11:00 a.m. Eastern Standard Time (EST) to discuss this earnings release and other Company business. To participate or listen to the call, dial 800-771-7838, ID number 21372621. An audio recording of the quarterly conference call will be available starting two hours after the start of the live broadcast. The audio recording will remain available until 1:00 p.m. EST on February 6, 2008 and can be obtained by calling 800-633-8284, ID number 21372621.
