ITEM 5. OTHER EVENT - EARNING RELEASE

CHANTILLY, VA. - July 23, 2003 - GTSI(R) Corp (Nasdaq: GTSI), a government
information technology solutions leader, today announced financial results for
the three and six-month periods ended June 30, 2003 (see attached tables).

Q2 PROFIT GROWTH
----------------

GTSI reported net income of $1.1 million, or $.13 per diluted share, in the
second quarter of 2003 versus net income of $772,000, or $.08 per diluted share,
for the same period last year. Sales for the second quarter of 2003 were $189.7
million as compared to $201.0 million for the same period last year. The Company
reported a net loss for the first half of 2003 of $614,000, or $.07 per diluted
share. Sales for the first half were $368.6 million.

Dendy Young, Chairman and Chief Executive Officer of GTSI, commented, "We are
pleased to report an increase in net income over last year's healthy second
quarter results, particularly during a period when government customers were not
aggressive in spending their budgeted IT dollars. Our sales organization has
built a substantial pipeline in the second quarter and continues to pursue new
opportunities. We expect that government purchasing habits will follow historic
trends and produce higher sales and improved operating results in the second
half of 2003 when compared to the first half of the year."

Gross margin in the second quarter of 2003 increased to 12.0% of total sales
from 7.5% of total sales due to three factors. First, 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)," resulted in reclassifying certain vendor funds as a
reduction in cost of sales. Second, GTSI's sales organization was effective in
securing an order for software inventory that had been impaired during 2002. As
a result, the company reversed a $1.4 million impairment charge. Third, the
company's underlying product margin increased from 7.5% in the second quarter of
2002 to 8.3% in the second quarter of 2003.

POSITIONED FOR PRESENT AND FUTURE GROWTH OPPORTUNITIES
------------------------------------------------------

Mr. Young continued, "GTSI is poised to achieve an expanded presence in the
Government market. One example of GTSI's commitment is the recent launch of the
Systems Integrator Solutions Group, which supports the solutions-based needs of
systems integrators who win large, performance-based Government contracts. GTSI
is also expanding its presence in the state and local Government market, most
notably through our recently commenced contract with U.S. Communities Purchasing
& Finance Agency."

Mr. Young concluded, "We believe that we will continue to see significant growth
in the Government IT market at the federal, the state, and the local levels, and
are prepared to capitalize on both the near-term and long-term opportunities it
presents. We continue to improve our sales capabilities, maintain high levels of
operating excellence, and strengthen vendor and customer service, all of which
are hallmarks of GTSI's business."

JUNE 2003 SALES
---------------

Sales for June 2003 were $81.0 million, representing a 13.5% decrease from June
2002 of $93.6 million. Month-end total backlog for June 2003 was $106.2 million
versus $118.4 million for the same period last


<PAGE>

year, while net bookings for June 2003 totaled $100.4 million as compared to
$96.7 million for June 2002, representing a 3.8% increase.

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

Tom Mutryn, GTSI's Senior Vice President and Chief Financial Officer, commented,
"GTSI's commitment to prudent fiscal management remains an important part of our
ability to grow and prosper. As of June 30, 2003, GTSI had working capital of
$55 million, no long-term debt and an unused and available credit facility. Our
expenses for the quarter increased 11.7% to $21.6 million after excluding the
offsets to expenses in the second quarter 2002 from vendor considerations. The
expense increase is largely the result of the investments we are making in
additional personnel to allow us to take full advantage of the expanding market
in the coming years."

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

As a consequence of adopting EITF 02-16 on January 1, 2003, GTSI recorded $5.5
million of vendor consideration as a reduction of cost of sales this quarter.
Prior to the adoption, these funds were accounted as an offset to operating
expense. Excluding the impact of EITF 02-16, and therefore on a non-GAAP basis,
the gross profit margin for the 2003 second quarter would have been 9.1%
compared to 7.5% in the same period of 2002. The non-GAAP gross profit margin is
included in this discussion to provide a meaningful comparison to prior periods.

ITEM 5. OTHER EVENT - EARNING RELEASE

CHANTILLY, VA. - July 23, 2003 - GTSI(R) Corp (Nasdaq: GTSI), a government
information technology solutions leader, today announced financial results for
the three and six-month periods ended June 30, 2003 (see attached tables).

Q2 PROFIT GROWTH
----------------

GTSI reported net income of $1.1 million, or $.13 per diluted share, in the
second quarter of 2003 versus net income of $772,000, or $.08 per diluted share,
for the same period last year. Sales for the second quarter of 2003 were $189.7
million as compared to $201.0 million for the same period last year. The Company
reported a net loss for the first half of 2003 of $614,000, or $.07 per diluted
share. Sales for the first half were $368.6 million.

Dendy Young, Chairman and Chief Executive Officer of GTSI, commented, "We are
pleased to report an increase in net income over last year's healthy second
quarter results, particularly during a period when government customers were not
aggressive in spending their budgeted IT dollars. Our sales organization has
built a substantial pipeline in the second quarter and continues to pursue new
opportunities. We expect that government purchasing habits will follow historic
trends and produce higher sales and improved operating results in the second
half of 2003 when compared to the first half of the year."

Gross margin in the second quarter of 2003 increased to 12.0% of total sales
from 7.5% of total sales due to three factors. First, 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)," resulted in reclassifying certain vendor funds as a
reduction in cost of sales. Second, GTSI's sales organization was effective in
securing an order for software inventory that had been impaired during 2002. As
a result, the company reversed a $1.4 million impairment charge. Third, the
company's underlying product margin increased from 7.5% in the second quarter of
2002 to 8.3% in the second quarter of 2003.

POSITIONED FOR PRESENT AND FUTURE GROWTH OPPORTUNITIES
------------------------------------------------------

Mr. Young continued, "GTSI is poised to achieve an expanded presence in the
Government market. One example of GTSI's commitment is the recent launch of the
Systems Integrator Solutions Group, which supports the solutions-based needs of
systems integrators who win large, performance-based Government contracts. GTSI
is also expanding its presence in the state and local Government market, most
notably through our recently commenced contract with U.S. Communities Purchasing
& Finance Agency."

Mr. Young concluded, "We believe that we will continue to see significant growth
in the Government IT market at the federal, the state, and the local levels, and
are prepared to capitalize on both the near-term and long-term opportunities it
presents. We continue to improve our sales capabilities, maintain high levels of
operating excellence, and strengthen vendor and customer service, all of which
are hallmarks of GTSI's business."

JUNE 2003 SALES
---------------

Sales for June 2003 were $81.0 million, representing a 13.5% decrease from June
2002 of $93.6 million. Month-end total backlog for June 2003 was $106.2 million
versus $118.4 million for the same period last
year, while net bookings for June 2003 totaled $100.4 million as compared to
$96.7 million for June 2002, representing a 3.8% increase.

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

Tom Mutryn, GTSI's Senior Vice President and Chief Financial Officer, commented,
"GTSI's commitment to prudent fiscal management remains an important part of our
ability to grow and prosper. As of June 30, 2003, GTSI had working capital of
$55 million, no long-term debt and an unused and available credit facility. Our
expenses for the quarter increased 11.7% to $21.6 million after excluding the
offsets to expenses in the second quarter 2002 from vendor considerations. The
expense increase is largely the result of the investments we are making in
additional personnel to allow us to take full advantage of the expanding market
in the coming years."

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

As a consequence of adopting EITF 02-16 on January 1, 2003, GTSI recorded $5.5
million of vendor consideration as a reduction of cost of sales this quarter.
Prior to the adoption, these funds were accounted as an offset to operating
expense. Excluding the impact of EITF 02-16, and therefore on a non-GAAP basis,
the gross profit margin for the 2003 second quarter would have been 9.1%
compared to 7.5% in the same period of 2002. The non-GAAP gross profit margin is
included in this discussion to provide a meaningful comparison to prior periods.
