GTSI Reports NASDAQ Update.

CHANTILLY, Va. -- GTSI[R] Corp. (NASDAQ:GTSI), today announced that it has received a letter from The NASDAQ Stock Market stating that because the Company has not filed its Form 10-Q for the quarter ended September 30, 2006 with the Securities and Exchange Commission (SEC), as required by Marketplace Rule 4310(c)(14), GTSI's common stock is subject to delisting from The NASDAQ Global Market. GTSI has subsequently requested the NASDAQ Listing Qualifications Panel for an extension until November 30th to file the Company's third quarter Form 10-Q and all previously announced restatements of it financial statements included in its Forms 10-K for 2003, 2004, 2005 and Form 10-Q for the quarter ended March 31, 2006. As previously disclosed, on November 2, 2006 the Panel granted the Company until November 30, 2006 to file, not only its second quarter Form 10-Q and amended Forms 10-K for 2003, 2004, and 2005 and Form 10-Q for the second quarter of 2006. The Company has requested that NASDAQ stay the most recent process pursuant to its previously granted extensions.

"We have, of course, continued to provide NASDAQ with updates regarding our previously announced restatements and NASDAQ recently granted us until November 30, 2006 to complete our work. In the meantime, GTSI has been working to complete the restated financial restatements for 2003, 2004 and 2005, as well as for the quarter ended March 31, 2006," said Jim Leto President and Chief Executive Officer of GTSI.

"Our finance team and GTSI's independent auditors have made significant progress towards completing the restatement and are preparing to file the new financials as soon as possible," said Leto. "As a Company, we are looking forward to returning to focus our energy on providing technology solutions and services for our government customers and building shareholder value."

The Company is in the process of amending and restating its 2003, 2004, 2005 and Q1 2006 financial statements. While there is no assurance, the Company expects to avoid delisting of its common stock from The NASDAQ Global Market by filing all required statements and its Forms 10-Q for June 30, 2006 and September 30, 2006 with the SEC before delisting would otherwise take effect.
