GTSI Provides Preliminary Results for 2007

Significantly narrows loss and materially reduces operating expenses

CHANTILLY, VA., January 22, 2008 – GTSI Corp. (NASDAQ: GTSI), an Enterprise IT infrastructure solutions and services provider to government, today announced that the Company is updating its 2007 financial expectations. 

“While the Company expects a net loss for 2007, we believe such loss will be significantly lower than last year. Although we anticipated delivering net income for 2007, the federal government’s continuing resolution impacted our ability to meet our expectations,” said Jim Leto, GTSI’s Chief Executive Officer. “During the fourth quarter, we had over $100 million in orders that we anticipated to close in the quarter pushed into 2008: much of this amount was due to federal funding constraints. President Bush signed the budget funding bill in the final days of the quarter, and it is anticipated that a normal funding flow will occur in the later portion of the first quarter.

“For the first time in three years we expect to deliver profitability for two consecutive quarters, the third and fourth quarters of 2007,” said Leto. “We believe the preliminary results of the fourth quarter indicate that the strategic decision to move away from commodity orders and into larger core technology product orders, infrastructure solutions and professional and financial services contracts, which have a longer sales cycle, is taking shape. In addition to continuing to implement our plan on moving away from small product sales, we will continue to focus on gaining efficiencies through out the organization. While we are pleased that we have materially reduced operating expenses in 2007, we are going to accelerate our efforts to reduce expenses in areas of the company which focus on lower margin business, continue to improve automation, as well as invest in our professional and financial services capabilities.”

The Company expects to release full fourth quarter and 2007 results in early March 2008 and hold a conference call on the day of the release.
