Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On August 14, 2006, GTSI Corp. (“Company” or “GTSI”) received a Nasdaq Staff Determination stating that GTSI failed to satisfy the requirements for continued listing under Nasdaq Market Place Rule 4310(c)(14) as a result of GTSI’s failure to file its Quarterly Report on Form 10-Q for the period ended June 30, 2006 with the Securities and Exchange Commission (“SEC”), and that the Company’s securities would be subject to delisting from the Nasdaq National Stock Market.

GTSI requested, and was granted, a hearing before the Nasdaq Listing Qualification Panel (“Panel”) to review the Staff Determination which will stay the delisting pending the final written decision of the Panel. This hearing is scheduled for September 14, 2006.

While there is no assurance, the Company expects to avoid delisting of its common stock from The Nasdaq National Market by filing its Form 10-Q for the period ended June 30, 2006 with the SEC before delisting would otherwise take effect.

Exhibit 99.1

GTSI Reports Receipt of Nasdaq Staff Determination Letter

CHANTILLY, VA. — August 16, 2006 — GTSIÒ Corp. (Nasdaq: GTSI), today announced that it has received a staff determination letter from The Nasdaq Stock Market stating that because the Company has not filed its quarterly report on Form 10-Q for the period ending June 30, 2006 with the Securities and Exchange Commission (SEC), as required by Market Place Rule 4310(c)(14), GTSI’s common stock is subject to delisting from The Nasdaq National Market.  GTSI expects to request a hearing with Nasdaq which would stay the delisting pending the determination of NASDAQ’s hearing panel.

“This notification is standard operating procedure for Nasdaq,” said Jim Leto President and Chief Executive Officer of GTSI.  “We are confident that the thorough review of our financials is the prudent action to take, which resulted in the late filing of the 10-Q.  We look forward to presenting our plan of action to Nasdaq’s hearing panel.”

The company is in the process of amending and restating its 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 National Market by filing its Form 10-Q for June 30, 2006 with the SEC before delisting would otherwise take effect.
