ITEM 4.02 NON-RELIANCE ON PREVIOUSLY ISSUED FINANCIAL STATEMENTS OR A RELATED AUDIT REPORT OR COMPLETED INTERIM REVIEW.

(a) On September 15, 2008, the Audit Committee of the Board of Directors of GTSI Corp. (the “Company”), after discussion with the Company’s management, concluded that the financial statements of the Company included in its quarterly report on Form 10-Q for the quarter ended June 30, 2008, should no longer be relied upon because of an error in the unaudited consolidated statements of operations for the three and six months ended June 30, 2008.

On September 19, 2008, the Company issued a press release announcing that it would restate its financial statements included in its Form 10-Q for the quarter ended June 30, 2008 and concurrently with the filing of this Current Report on Form 8-K the Company included such restated financial statements in an amendment to its Form 10-Q for the quarter ended June 30, 2008.

The Company concluded that previously reported financial statement information required restatement to correct an error in the accounting for the cost of sales and the related impact on selling, general and administrative costs to record additional incentive compensation costs due to the change in loss before income taxes associated with the error. In May 2008, the Company launched a system upgrade to its Enterprise Management System (“GEMS”). During the upgrade process, many GEMS reports were altered, including the cost of sales data collected in the logic reporting database. Because of a series of change management control failures during the GEMS upgrade process, the validation process of the cost of sales feed to the logic reporting database was incomplete; resulting in lost data and an overstatement of cost of sales for the three months ended June 30, 2008. For the three and six months ended June 30, 2008, the deferred cost of sales on the balance sheet was understated and cost of sales in the statement of operations was overstated by $2.1 million. Incentive compensation costs increased by $0.5 million based on the revised loss before income taxes. An additional immaterial service revenue entry of $0.1 million was also recorded as part of the restatement to correct an error for the three months ended June 30, 2008.

The Audit Committee and management of the Company have discussed the matters referenced above, including the restatement of the Company’s unaudited consolidated financial statements included in the Company’s Form 10-Q for the quarter ended June 30, 2008, with PricewaterhouseCoopers LLP, the Company’s independent registered public accounting firm.
