GTSI Reports Second Quarter Results

Transformation into an enterprise solutions and professional services
provider takes shape

CHANTILLY, VA. — August 14, 2007 — GTSIÒ Corp. (NASDAQ: GTSI), an enterprise solutions and services provider, today announced financial results for the quarter ended June 30, 2007.

For the second quarter of 2007, GTSI reported sales of $153.6 million, compared to $144.1 million in first quarter of 2007 and a $181.0 million for the second quarter of 2006. Professional services delivered $21.7 million in revenue during the second quarter as compared to $15.6 million in the second quarter of 2006. The shift in top line is the direct result of GTSI’s strategic plan to reduce reliance on lower margin orders in an effort to improve annual profitability. Operating expenses were $26.3 million in the second quarter 2007, a reduction of $0.9 million, or 3% for the same period in 2006. The quarter resulted in a net loss of $3.6 million ($0.38 per share) which was impacted by increases in non-cash stock option expenses and lower vendor incentives.

“GTSI continued to make steady progress during the quarter with focus on returning to profitability for the year,” said Jim Leto, President and Chief Executive Officer of GTSI. “Our top line, gross margin percent and bottom line results were on budget and our operating expenses were ahead of plan. We are rigidly controlling expenses and are working to further reduce costs in the business. Like most government contractors, GTSI was significantly impacted during the quarter by delays in war spending and underfunded civilian budgets. We have, however, built a highly visible and strong pipeline, which leads us to believe that we will have a strong finish for 2007.”

Since the quarter ended, GTSI has begun the rollout of its touchless order process with the goal of taking customer orders from the GTSI.com platform through a fulfillment partner without the need for interaction from GTSI employees. GTSI has 12 web based portals which are customized for either a customer or a specific contract. Recently, GTSI went live with the procurement management portion of this system and saw 70% of the orders flow through the procurement process with 96% of these orders flowing electronically to a set of key fulfillment partners on several hundred orders. A series of additional enhancements will be launched in a four phase strategy designed to mitigate disruption during the government peak buying season in the third quarter and GTSI’s peak fulfillment period during the fourth quarter. GTSI has established links with its major fulfillment partners, as well as several manufacturers, with a goal to have the vast majority of orders on all portals in the touchless mode in the first quarter of 2008. In addition, these same system upgrades will have significant benefit to phone placed orders, allowing basic commodity orders to pass through GTSI with a minimum of GTSI employee involvement. This process change is allowing the Company’s sales and engineering organizations to focus on higher end solutions and service infrastructure opportunities.

During the quarter, GTSI began working with a new set of contracts with the Army and NASA. “When new contracts commence, even recompetes such as ITES and SEWP, the procurement cycle changes. It takes time for new program offices to start up and new technology solutions be added to these contracts, which delay utilization. In the case of ITES and SEWP, which are among GTSI’s most successful contracts, we have seen significant activity in these contracts during the later part of the second quarter and the beginning of the third quarter,” added Leto.

“GTSI’s ability to execute on its plan and forecast our business results is remarkably different than it was just a few quarters ago,” said Leto. “The men and women of GTSI have stepped up and met each challenge presented and answered them with exceptional performance. The speed of our recovery is deliberate, our path is well marked. This is a team that sets out its goals and acts. We are in the midst of a remarkable recovery, but we have much work to do. I am confident that we will not merely endure, but that we will prevail.”

Operations and Financial Update

Joe Ragan, GTSI’s Senior Vice President and Chief Financial Officer, said, “In the second quarter we saw some changes in our revenue mix decreasing the lower end commodity business which impacted our top line revenue. In addition, as the government continues to go directly to manufacturers for larger commodity purchases, we saw volume incentive rebates fall $1.6 million, from the second quarter of 2006. This coupled with expenses of $400,000 associated with the shareholder approved long-term incentive program (LTIP) impacted GTSI’s net income performance. The LTIP will factor into each quarter going forward, increasing non-cash expenses by approximately $500,000.”

“Our balance sheet remains very strong,” said Ragan. “We had average day’s sales outstanding for the second quarter of 44 days, coupled with a significant decrease in merchandise inventory. A year ago our liquidity was tight, today we enjoy larger lines of credit with key partners and we have been out of our bank line for the past three weeks.”
