Tri-S Security Announces Results

For the 1^st Quarter Ended March 31, 2009

Sale of Cornwall business will reduce debt by approximately $7 million.

ATLANTA – Friday, May 15, 2009 – Tri-S Security Corp. (NASDAQ: TRIS), a provider of security services for government entities, today announced its results of operations for the first quarter ended March 31, 2009. Tri-S provides security services through its wholly-owned subsidiary, Paragon Systems, Inc. (“Paragon”).

First Quarter Ended March 31, 2009

• Revenues increased 80% to $29.3 million for the quarter ended March 31, 2009.

• Gross profit increased 28% to $0.9 million from a year ago.

• Gross margins were 3.1% compared to 4.3% a year ago. The difference between 2009 and 2008 is primarily attributable to an existing contract awarded to Paragon with a lower margin.

• EBITDA, as adjusted (see “EBITDA, as adjusted” definition below), declined to a negative $398,000 from a break-even position a year ago.

• Net loss per basic and diluted share was $(0.77) for the quarter ended March 31, 2009, compared to $(0.51) a year ago.

Recent Highlights

• In March 2009, Tri-S Security determined to sell substantially all of the assets (except accounts receivable) of its wholly-owned subsidiary, The Cornwall Group, Inc. (“Cornwall”), and certain of its subsidiaries. Cornwall is based in Miami, Florida and provides physical security for clients in Miami, Fort Lauderdale, and West Palm Beach, Florida. Tri-S Security determined to sell the Cornwall business so that Tri-S could focus on growing the government business and reduce its overall debt load. The sale was completed on May 13, 2009. This transaction will reduce our overall debt load by approximately $7.0 million, $750,000 of which will be held in escrow to secure the continuation of certain contracts transferred as part of the sale.

• Total Paragon contract pipeline of approximately $583 million, all of which has already been bid. We expect these contracts to be awarded over the next six months.

“Our top line growth showed significant improvement compared to the first quarter of 2008 and was stable compared to the previous quarter ended December 31, 2008,” said Ronald Farrell, CEO, Tri-S Security Corp. “We believe our contract pipeline continues to be strong and we remain very encouraged about winning new contracts at Paragon. With our current book of business, we can anticipate revenue for 2009 through 2011 of approximately $125 million per year,” added Farrell.

“The trends in our contract pipeline remain very encouraging for continued top line growth. I am pleased we were able to complete the sale of the Cornwall business and to reduce our debt by approximately $7.0 million. I am optimistic about our 2009 results based upon our first quarter numbers,” Farrell concluded.

Financial Discussion for First Quarter Ended March 31, 2009

During the first quarter of 2009, revenue for Tri-S Security grew 80% to $29.3 million from $16.3 million in the first quarter of 2008. This increase was the result of five new federal contracts, net of four contract expirations at Paragon.

The gross profit for the first quarter of 2009 was $0.9 million compared to $0.7 million for the first quarter of 2008. Included in these figures are start-up costs totaling $0.5 million for both quarters.

Gross margins were 3.1% compared to 4.3% a year ago. The difference between 2009 and 2008 is primarily attributable to an existing contract awarded to Paragon with a lower margin.

General and administrative costs were $2.0 million for the first quarter of 2009 compared to $1.7 million in the first quarter of 2008. General and administrative costs represented 7% of revenue for the first quarter of 2009 down from 10% of revenue in the same quarter for 2008.

The operating loss for the first quarter of 2009 was $1.3 million, compared to an operating loss of $1.2 million for the first quarter of 2008. Included in these figures are start-up costs totaling $0.5 million for both quarters.

EBITDA, as adjusted, was a negative $398,000 for the first quarter of 2009 as compared to break even for the first quarter of 2008.

Interest expense, net, increased to $1.4 million in the first quarter of 2009 compared to $0.8 million in the first quarter of 2008. This increase is primarily attributable to a higher borrowing base due to increased revenue and fees on our over advance. As a result, the net loss from continuing operations before income tax was $2.6 million in the first quarter of 2009 compared to $1.9 million in the comparable period last year.

A loss of $0.6 million for discontinued operations relating to Cornwall was recorded in the quarter ended March 31, 2009 and $0.2 million for the quarter ended March 31, 2008. Net loss for the first quarter of 2009 was $3.2 million compared to a net loss of $2.1 million in the first quarter of 2008.

In this release, we use the non-GAAP financial measure, EBITDA, as adjusted. EBITDA, as adjusted, is calculated as earnings before interest; taxes; depreciation and amortization; loss from discontinued operations; non-cash stock-based compensation; start–up costs on new contracts; and other income/expense. A reconciliation of EBITDA, as adjusted, to net loss for the quarters ended March 31, 2009 and 2008, is attached to this press release.
