Exhibit 99.1

ATS Corporation to Acquire Number Six Software, Inc.

Expands Client Base and Suite of Service Offerings

Transaction to be Accretive

MCLEAN, VA – (BUSINESSWIRE) — October 15, 2007. ATS Corporation (“ATSC”) (OTCBB:ATCT), a leading information technology company that delivers innovative technology solutions to federal, state, and local government organizations, today announced the signing of a definitive agreement to acquire Number Six Software, Inc. (“Number Six”), a provider of application development and information technology consulting to both government and commercial customers.  This acquisition supports ATSC’s strategic growth plan to broaden its information technology services expertise and add new customers in each of ATSC’s target sectors.   Closing of the transaction is subject to customary conditions, including approval by the stockholders of Number Six, and is anticipated within the next thirty days.

Number Six, a privately-held company headquartered in Vienna, Virginia, employs approximately 175 professionals supporting customers in both civilian and defense-related federal agencies, as well as in the commercial sector.  With this transaction, ATSC will continue to serve a similar balanced mix of civilian, defense, public safety and commercial customers by adding clients in each sector.

ATSC expects Number Six to generate annual revenues of approximately $33 million in 2007 with EBITDA (earnings before interest, taxes, depreciation and amortization) unadjusted for potential synergies of approximately $3.6 million. EBITDA is not a recognized term under US generally accepted accounting principles and does not purport to be an alternative to net income as a measure of operating performance or to cash flows from operating activities as a measure of liquidity.

Further, ATSC expects approximately 15% in revenue growth for Number Six in 2008, with $1.5 to $2.0 million in potential EBITDA growth and synergies over the next 12 to 18 months through a combination with ATSC operations.  As a result, ATSC expects the transaction to be accretive to earnings in 2008.

ATSC Chairman, President and Chief Executive Officer, Dr. Edward Bersoff, stated, “Number Six represents a significant opportunity to expand both our client roster and service offerings in both government and commercial markets.  This transaction also represents an important opportunity to increase our scale and establish a strong platform for growth in 2008 and beyond.  We look forward to the continuing successes and contributions of Number Six’s strong management team.”

Number Six’s Chief Operating Officer, Mike Bonamassa commented, “We are excited to become a part of ATSC and believe that the combined strength of the two companies with very complementary service offerings will create many immediate and long-term benefits to both our customers and employees.”

Under the terms of the definitive agreement, ATSC will acquire Number Six for a purchase price of approximately $36 million, including approximately $3 million in the form of ATSC common stock valued at the average price over the 15 day period before the closing of the transaction and promissory notes and deferred payments totaling $6 million.  The cash component of the purchase price is offset in part by negotiated items expected to benefit ATSC and reduce the net cash outlay associated with the transaction.

Agility Advisors acted as financial advisor to Number Six.
