Exhibit 99.1

ATS Corporation Announces Financial Results for the Second Quarter Ended June 30, 2008 and Bolsters Executive Team

MCLEAN, VA – (BUSINESSWIRE) – August 7, 2008, ATS Corporation (“ATSC” or the “Company”) (OTCBB:ATCT), a leading information technology company that delivers innovative technology solutions to government and commercial organizations, today announced operating results for the second quarter ended June 30, 2008 and the appointment of a Chief Operating Officer.

Second Quarter Results

ATSC reported revenue of $33.8 million for the second quarter of 2008.  Revenue for the second quarter increased by 29.0% over second quarter FY07 revenue of $26.2 million.  Acquisitions in 2007 strongly influenced second quarter revenue growth.  Revenue from commercial contracts increased $0.7 million to $7.2 million, or 11%.  Revenue from government contracts increased $6.1 million to $26.6 million, or 30%.

Operating income for the quarter was $1.0 million and the net income for the quarter was $67,000 or $0.00 per diluted share, compared to operating income of $280,000 and net income of $125,000 for the second quarter of 2007.   EBITDA (1) was $3.1 million for the quarter, resulting in an EBITDA margin of 9.0%.  Net income included $930,000 in amortization of intangibles related to the acquisition of Advanced Technology Systems (“ATS”) by its parent ATSC.   Net income adjusted for the amortization of ATS-related intangibles (2) was $1.0 million or $0.05 per diluted share.

Backlog as of June 30, 2008 was approximately $187.1 million of which $77.1 million was funded.  Days sales outstanding were 86 at the end of the second quarter of fiscal year 2008, excluding approximately $3.6 million in receivables from one of the Company’s largest and typically prompt paying customers who recently changed their contracting procedures, causing a payment delay that was resolved shortly after the close of the quarter.

As of June 30, 2008, ATSC’s balance sheet included debt of $43.8 million on its revolving credit facility and approximately $5.9 million in promissory notes related to the acquisitions of Potomac Management Group, Inc. and Number Six Software, Inc.  Additionally, the balance sheet included $96.8 million in stockholders’ equity.

On April 8, 2008, the Company announced an offer to holders of all 36,380,195 outstanding, publicly-traded warrants, that it would permit the early exercise of the warrants on amended terms, for a limited time.  Under the tender offer, a total of 33,400,020 warrants were exercised.

Six-Month Results

ATSC reported revenue of $68.7 million for the first six months of 2008.  Revenue for the first six months increased by 38% over the first six months of 2007.  Acquisitions in 2007 strongly influenced second quarter revenue growth.  Additionally, the full six months in 2008 of operations is compared to five and one half months in 2007, further contributing to the increase.

Operating income for the first six months of 2008 was $2.1 million and the net income for the first six months was $342,000 or $0.02 per diluted share, compared to operating income of $396,000 and a net loss of $6.6 million for the first six months of 2007.   EBITDA (1) was $6.3 million for the first six months, resulting in an EBITDA margin of 9.1%.  Net income included $1.9 million in amortization

of intangibles related to the acquisition of Advanced Technology Systems (“ATS”) by its parent ATSC.   Net income adjusted for the amortization of ATS-related intangibles (2) was $2.2 million, or $0.11 per diluted share.

Second Quarter Highlights

Second quarter new bookings totaled $15.5 million, including new awards from the U.S. Coast Guard, the National Institutes of Health, and the Federal Bureau of Investigation.   Subsequent to the end of the quarter, the Company was notified of several new awards in its public safety business totaling over $4 million.

ATSC President and Chief Executive Officer Dr. Edward H. Bersoff stated, “We were pleased to continue to maintain our target 9% EBITDA margins for the quarter, particularly in light of the disappointing revenue results.   Our lower than anticipated revenue for the quarter reflects substantial weakness in our commercial contracts.  It is also important to note that our work at Fannie Mae only experienced a slight decline in revenue quarter over quarter despite its very public issues, and we are still expecting that Fannie Mae will be a strong contributor to our revenue in the quarters to come.  Additionally, we have been recently notified of several new awards in our defense and public safety line of work totaling over $4 million, further positioning our defense and homeland security business unit as the sector with the strongest near term growth potential.  One of these awards represents a new area of work for our public safety business in records management which we believe will open a new market opportunity for us to further expand our systems integration capabilities.”

Bersoff continued, “Our primary objective at this point is to concentrate on our new business efforts and a return to an increased backlog.  We do, however, continue to focus on keeping our costs in line with our current revenue run rate and will seek ways to reduce expenses.  For example, our move into a new building this quarter will save us over $1.5 million annually.”

“Finally, we completed our warrant program in May and were pleased to see a reduction of 92% of our outstanding warrants,” concluded Bersoff.

ATSC Senior Vice President and Chief Financial Officer Pamela Little added, “We previously reported integration-related issues with one of our acquisitions that increased our DSO.  While we reported a modest decrease as of June 30, 2008, factoring in the excluded receivables, we have seen significant collections in the month of July and resolved many of those billing issues we were experiencing.  As a result, we have paid our revolving credit facility down to approximately $39.4 million or a decrease of $4.4 million since the end of June.”

Management’s Revised Outlook

Based on current market trends and current ATSC backlog and bid activity, the Company is updating its guidance for 2008.  The Company is now forecasting its revenue for the year to be between $129 and $135 million and EBITDA (1) to be between $11.5 and $13.0 million.   The revised guidance is based on expected continued weakness in our commercial business activities.

Bersoff added, “We will continue to closely monitor the alignment of our expenses with revenue performance to manage our business to achieve our targeted EBITDA margins, and we remain confident that our investment in business development and increased bid activity will generate growth for the Company.”

Chief Operating Officer Appointment

Today, ATSC also announced the appointment of George Troendle as the Chief Operating Officer of the Company effective August 11, 2008.  Mr. Troendle has served on the Company’s

Board of Directors since June of 2007, although he will be resigning from the board in connection with his new officer position.  Mr. Troendle was the founder, Chief Executive Officer and Director of Resource Consultants, Inc. (“RCI”), a broadly diversified technology company specializing in support of government agencies, particularly defense and homeland security.  In 2005, RCI became part of Serco North America, a $500 million division of Serco Group, a $3.5 billion international government services company.  Mr. Troendle became President of Serco North America and served in that role until stepping down in 2006.

Bersoff commented, “We are fortunate to add such a seasoned executive to our senior management team.  George’s prior experience and successful track record building a company in the defense and homeland security markets will bring tremendous value to ATSC, particularly as ATSC is aggressively pursuing avenues to build its backlog.”

(1) EBITDA is a non-GAAP measure that is defined as GAAP net income plus other expense, interest expense, income taxes, and depreciation and amortization.  We have provided EBITDA because we believe it is a commonly used measure of financial performance in comparable companies and is provided to help investors evaluate companies on a consistent basis, as well as to enhance an understanding of our operating results.  EBITDA is not a recognized term under U.S. GAAP and does not purport to be an alternative to net income as a measure of operating performance or the cash flows from operating activities as a measure of liquidity.  Please refer to the table at the bottom of the statement of operations in this release that reconciles GAAP net income to EBITDA.

(2) Net income adjusted for the amortization of ATS-related intangibles is a non-GAAP measure that is defined as GAAP net income plus the amortization of intangibles related to the Company’s platform acquisition of Advanced Technology Systems, Inc.  We have provided this adjusted net income and the associated earnings per share because we believe it is a better measure for comparison with our peer group.
