Common Stock

ATLANTA, June 05,2009 /PRNewswire-FirstCall/ — Tri-S Security Corp. (NASDAQ: TRIS), a provider of security services for government entities, today announced that it received written notification on June 3, 2009, that a NASDAQ Listing Qualifications Panel has determined to delist the Company’s securities from The Nasdaq Capital Market, effective as of the open of business on Friday, June 5, 2009. The delisting is the result of the Company’s failure to meet the $2.5 million stockholders’ equity requirement or one of the alternative continued listing criteria set forth in NASDAQ Marketplace Rule 4310(c)(3).

The Company has been advised by Pink OTC Markets Inc., which operates an electronic quotation service for securities traded over-the-counter, that its securities are immediately eligible for quotation in the Pink Sheets effective as of the open of business on June 5, 2009. The Company’s common stock will continue to trade in the Pink Sheets under the symbol TRIS.

The Company’s securities may, in the future, also be quoted on the Over-the-Counter Bulletin Board (the “OTCBB”), an electronic quotation service maintained by the Financial Industry Regulatory Authority (“FINRA”), provided that a market maker in the Company’s securities files an application to register and quote the securities and such application is cleared by FINRA. The Company is in the process of engaging a market maker and causing the required application to be filed with FINRA for quotation of the Company’s securities on the OTCBB.
