INTEGRAL SYSTEMS ANNOUNCES FINANCIAL RESULTS

FOR THE THIRD QUARTER OF 2003

Company Also Announces Quarterly Dividend of Three Cents Per Share

Lanham, Md., August 11, 2003—Integral Systems, Inc. (NASDAQ: ISYS) today reported financial results for the third quarter of fiscal 2003. Revenues for the quarter were $19.3 million, up from $14.4 million in the third quarter of fiscal 2002—an increase of approximately 34%. Operating income increased almost four-fold, rising to $1.4 million for the quarter, versus $400,000 in the third quarter of fiscal 2002.

Net income decreased to $170,000 in the third quarter of fiscal 2003 from $960,000 in the third quarter of fiscal 2002, a decrease of 82%. The decline is attributable to approximately $1.4 million of other expense recorded in the third quarter of 2003 related to the Company’s investment in the common stock of Loral Space and Communications Ltd (LOR). LOR filed a voluntary petition for bankruptcy under Chapter 11 of the Federal Bankruptcy Code on July 15, 2003. As a result, the Company considers the investment to be permanently impaired. On a fully diluted per share basis, net income declined to $.02 during the third quarter of fiscal 2003 from $.10 during the third quarter of fiscal 2002.

“Our third quarter was not particularly stellar in terms of earnings performance,” commented Steven R. Chamberlain, Chairman and Chief Executive Officer. “In addition to the LOR write-off, our SAT and Newpoint subsidiaries have yet to turn the corner to profitability, both posting operating losses greater than originally anticipated. We also experienced a couple of contract overruns in our core command and control business, which caused that operation to be less profitable than it has been in recent quarters. Fortunately, operating income generated by our subsidiary RT Logic, allowed us to operate in the black on a consolidated basis for the quarter.”

Operating results for the three months ended June 30, 2003 include full quarter results for RT Logic. The Company did not own RT Logic in the third quarter of the prior year.

For the nine months ended June 30, 2003, revenues were $58.9 million compared to $35.3 million for the nine months ended June 30, 2002 – an increase of $23.6 million, or 67%. For the current nine-month period, operating income was $5.0 million compared to $1.2 million for the same period last year, while net income increased to $2.5 million from $2 million, an increase of approximately $500,000. On a fully diluted per share basis, net income increased to $.26 during the nine months ended June 30, 2003 from $.22 during the same period of fiscal 2002.

“Despite our third quarter setbacks, the big picture actually remains quite optimistic,” commented Chamberlain. “First, I am pleased that our year to date operating income and EPS exceed last year’s numbers, even after the LOR write-off. Further, not only are we still on track to meet originally published guidance for revenue, net income and EPS, we are on target to exceed guidance for operating income by more than 30% for fiscal 2003. Looking forward to FY04, we should have our best year ever,” stated Chamberlain.

The Company also reported that its Board of Directors has approved the Company’s plan to pay a quarterly dividend of three cents per share beginning with the upcoming quarter ending September 30, 2003. “Because of the new tax laws favoring dividend payments coupled with our continued confidence in the Company’s future profitability, I believe that a recurring dividend payment will contribute to enhancing shareholder value,” said Chamberlain. Specifics regarding record dates and payment dates will be announced in future press releases.

Mr. Chamberlain will host a conference call Wednesday, August 13, 2003 at 11:00 a.m. Eastern Time (ET). Chamberlain will discuss the earnings release and other Company prospects.
