ATS Corporation Announces Financial Results for the Second Quarter and Six Months Ended June 30, 2007

MCLEAN, VA — (MARKET WIRE) — August 7, 2007, McLean, VA. ATS Corporation (“ATSC” or “the Company”) (OTCBB:ATCT), a leading information technology company that delivers innovative technology solutions to federal, state, and local government organizations, today announced operating results for the second quarter and six months ended June 30, 2007.

Second Quarter Results

ATSC reported revenue of $26.2 million for the second quarter of 2007.  Operating income for the quarter was $280,000 and the net income for the quarter was $125,000.  Prior to the acquisition of Advanced Technology Systems, Inc.  (“ATS”) on January 16, 2007, ATSC was a blank check company without operating units or results.

As previously disclosed in its 2007 first quarter earnings call, ATSC continued to incur transition-related costs from the January transaction during the second quarter.  Actual transition costs were approximately $900,000 of amortization of intangibles associated with the ATS acquisition for the quarter ended June 30, 2007.  ATSC also incurred $323,000 in severance costs related to a reorganization of business units and $87,000 in expenses related to Sarbanes Oxley compliance initiatives.

Backlog as of June 30, 2007 was approximately $127.5 million, of which $41.5 million was funded.   Days sales outstanding were 77 at the end of the second quarter of fiscal year 2007.

As of June 30, 2007, ATSC’s balance sheet indicated no outstanding balance on our line of credit and $93.5 million in stockholders’ equity.

Six-Months Results

ATSC reported revenue of $49.7 million for the first six months of 2007.  Operating income and net loss for the six-month period were $396,000 and $6.6 million, respectively.   The loss included a loss of $6.9 million on derivative liabilities attributed to the Company’s warrants.  Effective March 14, 2007, the Company’s warrant agreement was clarified to state that ATSC was not required to net cash settle the instruments if unable to deliver shares of common stock to the warrant holders.  As a result, ATSC was no longer required to mark the warrants to market and the warrants were reclassified from liabilities to stockholders’ equity.  Prior to March 14, 2007, ATSC marked the warrants to market as liabilities and recognized gains or losses on the increase or decrease in the fair market value of the warrants.  The six months’ results reflect this reclassification that occurred after March 31, 2007.

Second Quarter Highlights

New contract awards and option extensions for the quarter included:

·$15 million contract with a leading financial institution

·$10 million subcontract with the Community Planning and Development agency within the Department of Housing and Urban Development to provide software design, implementation, development and maintenance

·$6.8 million option extension with the Office of the Undersecretary of Defense for Policy for information technology support services

·$3.9 million contract with the Yonkers, New York Police Department to implement a law enforcement records management system

·$800,000 option extension with an ATSC law enforcement customer for system and service administration

·$700,000 contract with CompSource Oklahoma to provide technology planning, consulting, and project oversight for the workers’ compensation business applications

·Three contracts totaling $4.5 million to support ATSC public safety customers

Major ATSC highlights and accomplishments during the quarter included:

·Reorganization of operations from six to four customer-focused areas: 1) federal civilian agencies;  2) defense and homeland security customers;  3) public safety which predominately serves state and local customers; and 4) Appix serving our commercial clients

·Addition of two new independent directors to the board, Ginger Lew and George Troendle, adding significant operating and transaction experience

·Completion of a new credit facility, expanding borrowing capacity to $50 million

·Appointment of Pamela Little to Chief Financial Officer, bringing 25 years of financial experience with government contractors and professional services firms to the ATSC management team

·Promotion of Shannon Brown and Joseph Mignogna to Senior Vice President, Federal Civilian Agencies and Senior Vice President, Defense and Homeland Security, respectively

·Engaged an internal auditor and third-party advisor to accelerate our Sarbanes Oxley compliance activities

·Authorized a $500,000 warrant repurchase program under which the Company purchased 870,533 warrants for approximately $351,000 in June and in July the Company purchased an additional 71,322 for approximately $29,000

ATSC President and Chief Executive Officer Dr. Edward H. Bersoff stated, “I continue to be pleased with the accomplishments achieved since the January 2007 transaction.  We generated stronger than expected profits for the quarter because we were able to execute on a reorganization of operations faster than planned, resulting in improved efficiency and reduced costs.”

Bersoff continued, “While margins have improved, market conditions have been challenging, leading to delays in new contract awards.  We believe the new business development team established in the first quarter has allowed us to build a strong platform for growth as the environment improves.   In fact, we submitted several bids over the last quarter that, if awarded to us, will significantly add to our contract backlog.”

Bersoff concluded, “Another positive development for the Company was the addition of Ginger Lew and George Troendle to ATSC’s Board of Directors. Ginger’s extensive business, government, and investment experience and George’s leadership in building a successful government services company will be tremendously valuable to ATSC as we continue to grow our Company.  Further, the addition of these two independent directors satisfies the corporate governance requirement for a NASDAQ listing.   Lastly, our expanded borrowing base will better support our working capital requirements and acquisition growth plans.”

ATSC will conduct a second quarter conference call on Tuesday, August 7, at 5:00 p.m EST.  The number for the live teleconference is 888-321-3075, conference ID #9091717.  A recorded replay of the teleconference will be available by telephone at 877-519-4471, conference ID#9091717 starting at 8.00 p.m EST on August 7, 2007 through 11:59 p.m EST on August 21, 2007.   A recorded replay of the teleconference will also be available on the Company website  (www.atsva.com) for one year from the conference call date.
