GTSI Reports Strong Third Quarter Financial Results
- ---------------------------------------------------

         NET INCOME UP 10%, QUARTER-END TOTAL BACKLOG AT $228.3 MILLION

            CLOSES ON A NEW AND EXPANDED $125 MILLION CREDIT FACILITY

CHANTILLY, VA. - October 28, 2003 - GTSI(R) Corp (Nasdaq: GTSI), a leading
government technology solutions provider, today announced financial results for
the three and nine-month periods ended September 30, 2003, and monthly sales
(see attached tables).

"GTSI proved once again that we are the preferred provider of information
technology solutions to the federal government. In September, a month that is
key to our whole year's success, GTSI performed at the highest levels with
bookings increasing over 13%, delivering a rock solid third quarter," said Dendy
Young, Chairman and Chief Executive Officer of GTSI. "The ability for GTSI to
continue at this pace appears to be strong, with the company booked backlog of
$228.3 million at the end of September."

Q3 EARNINGS AND PROFIT GROWTH
- -----------------------------

For the third quarter GTSI reported diluted earnings per share of $0.39. Net
income rose to $3.5 million in the third quarter of 2003, representing a 10%
increase over the net income of $3.1 million for the third quarter last year.
Net income for the 2003 third quarter included interest income of $840,000
versus interest income of $1.3 million in the third quarter of 2002. Sales for
the third quarter of 2003 were $273.1 million as compared to $276.8 million for
the same period last year. The Company reported net income for the first nine
months of 2003 of $2.9 million, or $0.31 per diluted share. Sales for the first
nine months were $641.7 million.

Gross margin in the third quarter of 2003 increased to 10.1% of total sales from
8.1% of total sales. This increase is due primarily to the January 1, 2003
adoption of Emerging Issues Task Force ("EITF") Issue No. 02-16, "Accounting for
Consideration Received from a Vendor by a Customer (Including a Reseller of the
Vendor's Products)," which resulted in reclassifying in 2003 certain vendor
funds as a reduction in cost of sales. In addition, the Company's underlying
product margin showed a modest increase from the third quarter of 2002 to the
third quarter of 2003.

GTSI MAPS OUT CUSTOMER CENTRIC REALIGNMENT
- ------------------------------------------

Mr. Young continued, "Our customer continues to undergo dramatic change. For the
past two years we have seen more repositioning of the government than any time
in our 20-year existence. To better serve the government, we are streamlining
and realigning our sales and support teams to meet its changing needs."

Going forward, GTSI expects to continue to enhance its revenue by adding new
vendors and solutions, as well as expanding its sales coverage. Additionally,
the Company will selectively examine and evaluate acquisition candidates to
augment its internal growth. Gaining higher margin business, pricing and
purchasing smarter, and realizing operating efficiencies are expected to result
in higher profit margins.

Recent examples of margin expansion have been seen in the growth of GTSI service
offerings. During the quarter ended September 30, 2003, services generated $27.5
million in revenue a 39.6% increase of $7.8 million over the same period one
year ago.

SEPTEMBER 2003 SALES
- --------------------

Sales for September 2003 were $132.2 million, representing a 4.9% increase of
average daily sales from September 2002 of $120.0 million. Month-end total
backlog for September 2003 was $228.3 million or a 12.1% increase versus $203.6
million for the same period last year, while net bookings for September 2003
totaled $228.9 million as compared to $192.4 million for September 2002, a 13.3%
increase (see attached table).





FINANCIAL POSITION
- ------------------

Tom Mutryn, GTSI's Senior Vice President and Chief Financial Officer, commented,
"GTSI is in an enviable position of being debt free and having a healthy balance
sheet. Our expenses for the quarter increased 3% to $22.6 million over expenses
in the third quarter 2002, adjusted to remove the impact of vendor
considerations for that period."

Last week GTSI closed on a new $125 million credit facility meeting GTSI's
revolving line of credit and distribution financing needs.

Mutryn added, "We believe that the lender's commitment to the size of the credit
facility confirms GTSI's solid financial condition and reflects the confidence
that they have shown in our business models and prospects. Just as important,
this credit facility gives GTSI the ability to meet its ongoing credit needs and
to further its strategic goals and corporate development program in the coming
years."

NEW ACCOUNTING PRONOUNCEMENT
- ----------------------------

For comparative purposes, if the Company had applied EITF No. 02-16 to the
three-months ended September 30, 2002; gross margin would have increased from
$22.4 million to $25.9 million for the third quarter 2002. Gross margin
percentage would have increased from 8.1% to 9.3% for the quarter compared to
10.1% for the same period in 2003.
