GTSI Provides Preliminary Results for 2007

Significantly Narrows Loss and Materially Reduces Operating
Expenses
CHANTILLY, Va.--(Business Wire)--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 & 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
throughout 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.
