GTSI Reports Fourth Quarter and Full-Year Results for 2007

Gross margin expansion, reduction of expenses and narrowed loss led the way

CHANTILLY, VA., March 14, 2008 — GTSI Corp. (NASDAQ: GTSI), an Enterprise IT infrastructure solutions and services provider to government, today announced financial results for the quarter and year ended December 31, 2007.

“We continue to build the company to promote future growth in the programs and services area, with a focus on increasing margin and reducing the highs and lows of revenue capture,” said Jim Leto, GTSI’s President and Chief Executive Officer. “During the fourth quarter and throughout the year, we have consolidated our resources and activities around key strategic partners which have resulted in a more efficient ‘go to market’ strategy. This activity has seen some attrition in product sales, but it is a concerted effort to streamline overall operating performance.

“To offset some of the anticipated short-term revenue declines we have been implementing an expense reduction initiative which has resulted in the lowest levels of operating expenses in four years. We will continue in our efforts to reduce expenses throughout 2008, while making investments in the services areas of the business which will help us drive margin,” said Leto.

Financial Update

Joe Ragan, GTSI’s Senior Vice President and Chief Financial Officer, said, “We continue to execute our financial strategy driving performance resulting in a $30 million improvement in net cash provided by operating activities from 2006 to 2007, representing a remarkable turn around. Also since the end of 2007, we retired $10 million in subordinated debt which cost us over $1 million in interest expense in 2007.

“For the first time in three years we delivered profitability for two consecutive quarters, the third and fourth quarters of 2007,” said Ragan. “We believe 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.”

After extensive remediation efforts over the past two years GTSI management deems it has effective financial controls related to its compliance with the Sarbanes-Oxley Act requirements.

Fourth Quarter and Year-End Financial Results

For the fourth quarter 2007, GTSI reported sales of $224.5 million, compared to $284.5 million in the same period a year ago and reported net income of $3.3 million or $0.33 of earnings per diluted share versus net income of $9.5 million or $0.98 of earnings per diluted shares in the fourth quarter of 2006. Operating expenses were $27.2 million down from $31.8 million in the fourth quarter of 2006. Gross margin in the fourth quarter of 2007 was 13.5%, down from 14.7% in the fourth quarter of 2006.

During the fourth quarter of 2006, GTSI reversed certain aged accrued liabilities of $5.8 million, decreasing cost of sales and increasing gross margin. For comparative purposes (a non-GAAP financial measure), adjusting for the fourth quarter of 2006 accrued liability reversal, net income would have been $3.7 million and earnings per diluted share would have been $0.38 for the quarter.

For the year ended December 31, 2007, GTSI reported sales of $723.5 million, a decrease from $863.0 in 2006, and reported a net loss of $1.8 million, after tax expenses of $0.6 million, or $0.18 of net loss per diluted share compared to a net loss of $3.0 million and $0.32 of net loss per diluted share in 2006. Operating expenses were down year over year at $106.3 million versus $115.2 million for 2006. Gross margin for 2007 increased to 14.5% versus 13.2% for 2006.

During 2006, GTSI incurred one-time unfavorable expenses of $9.0 million and certain favorable adjustments of $10.9 million in 2006. For comparative purposed (a non-GAAP measure) after adjusting for the 2006 adjustments, net loss for 2006 was $4.9 million or $0.52 of net loss per diluted share for the year.

Marketplace Update

“We have seen growth in our federal civilian, state and local government customers,” said Leto. “Due to the late passage of a catch-all spending bill companies such as GTSI saw many anticipated contracting opportunities push from the fourth quarter of 2007 into 2008. The waning days of 2007 ended nearly two budget cycles of uncertainty for government agencies which did not know how much money they could invest in technology applications. While this spending bill presents opportunities to solve technology problems for our customers, the lag time in the funds flow was pushed into the first half of 2008. Government agencies moving away from GWACs and increasingly using their own task orders, gives GTSI an excellent opportunity for GTSI to take advantage of our reach across many agencies.”
