MCLEAN, VA – (BUSINESSWIRE) – August 5, 2009, 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, 2009.

Second Quarter Results

ATSC reported revenue of $30.3 million for the second quarter of 2009.  Revenue for the second quarter decreased by 10.4% over second quarter 2008 revenue of $33.8 million.  Revenue from commercial contracts decreased $1.2 million to $6.0 million, or 16.8%.  This decline resulted from the down-turn in the business climate that began in the fourth quarter of 2008 and continued into 2009.  Revenue from civilian and defense contracts decreased $2.6 million to $24.7 million, or 9.7%.  As previously reported, the most significant contract reduction was with the U.S. Coast Guard due to the conversion of a large contract to a small business set-aside, where we continue to perform in a subcontractor role.

Operating income for the quarter was $2.7 million and the net income for the quarter was $1.2 million or $0.05 per diluted share, compared to operating income of $1.0 million and net income of $67,000 for the second quarter of 2008.   EBITDA (1) was $3.5 million for the quarter, resulting in an EBITDA margin of 11.5%, compared to $3.1 million, or a margin of 9.0% for the second quarter of 2008.

Backlog as of June 30, 2009 was approximately $156.1 million, of which $49.5 million was funded.  Days sales outstanding (“DSO”) were 67 at the end of the second quarter of fiscal year 2009.

As of June 30, 2009, ATSC’s balance sheet included debt of $24.8 million on its revolving credit facility and approximately $3.4 million in promissory notes related to the acquisitions of Potomac Management Group, Inc. and Number Six Software, Inc.  Additionally, the balance sheet included $48.4 million in stockholders’ equity.

Six-Month Results

ATSC reported revenue of $57.4 million for the first six months of 2009.  Revenue for the first six months decreased by 16.4% over the first six months of 2008.  Revenue from commercial contracts decreased $5.1 million to $10.5 million, or 33.7%.  Revenue from civilian and defense contracts decreased $6.1 million to $46.9 million, or 11.5%.

Operating income for the first six months of 2009 was $4.4 million and the net income for the first six months was $1.6 million or $0.07 per diluted share, compared to operating income of $2.1 million and net income of $342,000 or $0.02 per diluted share for the first six months of 2008.   EBITDA (1) was $6.0 million for the first six months of 2009, resulting in an EBITDA margin of 10.4%, compared to $6.3 million, or a margin of 9.1% for the first six months of 2008.

Second Quarter Highlights and Management Comments

Second quarter new bookings totaled $7.2 million, primarily from add-ons or additional funding from the Department of Housing and Urban Development, the Pension Benefit Guarantee Corporation, and the Federal Housing Finance Agency.  Within our commercial consulting business areas, we expanded our work with several customers, including Blue Cross Blue Shield of Kansas, American International Group, Inc., WellPoint, Inc. and the South Carolina Home Builders Self Insurance Fund; and we began several engagements with new customers such as the American European Insurance Group and the State of Kansas.  Additionally, the Company won several new awards just after the close of the second quarter, including a re-compete contract to provide software development services to the U.S. Air Force, valued at approximately $5 million over the next year.

ATSC President and Chief Executive Officer Dr. Edward H. Bersoff stated, “We are pleased that our results for the second quarter show revenue growth from the first quarter and significant margin expansion.  As we reported in the first quarter of this year, we experienced a temporary, but significant downturn in our Fannie Mae business as it reorganized to operate under government conservatorship.  We’ve seen our Fannie Mae business increase in the second quarter versus the performance in the first quarter, and expect further improvements in the third quarter that will return us to levels comparable with last year’s revenue for this customer.”

Dr. Bersoff added further comments on the Company’s financial performance, “We were very pleased with our margin performance in the second quarter and ability to expand our EBITDA margins to 11.5%, even with an increase in our investment in business development of approximately 15% in the first six months of this year compared to the same period last year.   We have also improved our DSO which were at 67 days at the end of the second quarter, a drop from 79 at the end of the first quarter of 2009.  As a result of the strong profits and improvements in cash flow, we have been able to further pay down our debt and continue to improve our operating flexibility.”

Management’s Revised Outlook

Based on current market trends and current ATSC backlog and bid activity, the Company is updating its revenue guidance for 2009.  The Company is now forecasting its revenue for the year to be between $121 and $125 million.  The Company is reiterating its EBITDA (1) guidance range of $11.5 and $13.0 million.

Dr. Bersoff commented, “As we have proven in earlier quarters, we will continue to monitor closely the alignment of our expenses with revenue performance and manage our business to achieve our targeted EBITDA margins.  Furthermore, we are encouraged with the quarter over quarter revenue growth this period, in particular, the positive developments in our commercial business areas after several challenging quarters.  We expect an increase in award activity in the second half of the year in both our government and commercial business areas, which will provide strong momentum for further growth as we enter 2010.”

(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.
