Item 8.01 Other Events.

GTSI Corp. (the “Company”) has determined that it is no longer an accelerated filer for purposes of its Annual Report on Form 10-K for the fiscal year ended December 31, 2006 because the Company’s public float was below the required threshold as of the last business day of its 2006 completed second fiscal quarter ended June 30, 2006. As a result, as a non-accelerated filer the Company is not required to file its Annual Report on Form 10-K for the year ended December 31, 2006 with the Securities and Exchange Commission until April 2, 2007.
