MCLEAN, VA – (BUSINESSWIRE) – November 9, 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 third quarter ended September 30, 2009.

Third Quarter Results

ATSC reported revenue of $32.1 million for the third quarter of 2009.  Revenue for the third quarter increased by 0.1% over third quarter 2008 revenue of $32.0 million.  Operating income for the quarter was $3.9 million and the net income for the quarter was $2.0 million or $0.09 per diluted share, compared to an operating loss of $55.8 million and a net loss of $51.0 million for the third quarter of 2008.  The operating and net losses incurred in the third quarter of 2008 were due to a $56.8 million, non-cash goodwill and intangible asset impairment charge.   EBITDA (1) was $4.7 million for this year’s third quarter, resulting in an EBITDA margin of 14.7%, compared to $3.4 million, or a margin of 10.5% for the third quarter of 2008.

Backlog as of September 30, 2009 was approximately $153.1 million, of which $51.8 million was funded.  Days sales outstanding (“DSO”) were 61 at the end of the third quarter of fiscal year 2009.

As of September 30, 2009, ATSC’s balance sheet included debt of $18.5 million on its revolving credit facility and approximately $3.2 million in promissory notes related to the acquisitions of Potomac Management Group, Inc. and Number Six Software, Inc.  Additionally, the balance sheet included $50.6 million in stockholders’ equity.

Nine-Month Results

ATSC reported revenue of $89.5 million for the first nine months of 2009.  Operating income for the first nine months of 2009 was $8.3 million and the net income for the period was $3.6 million or $0.16 per diluted share, compared to an operating loss of $53.7 million and a net loss of $50.6 million for the first nine months of 2008.  The 2008 results reflect the impairment charge incurred in the third quarter of 2008, as discussed under “Third Quarter Results”.   EBITDA (1) was $10.7 million for the first nine months of 2009, resulting in an EBITDA margin of 11.9%, compared to an Adjusted EBITDA (2) of $9.6 million, or a margin of 9.6% for the first nine months of 2008.

Third Quarter Highlights and Management Comments

Third quarter new bookings totaled $30 million, primarily from add-ons or additional funding from the Department of Housing and Urban Development, the Pension Benefit Guaranty Corporation (“PBGC”), the Defense Logistics Agency, and the Defense Technology Security Administration, among others.   Within our commercial business, we expanded our work with several customers, primarily Fannie Mae; and we began new engagements with Neustar, Inc. and Perceptive Software, Inc. Additionally, the Company won a new award after the close of the third quarter to provide software development services to PBGC, valued at $12.2 million over 5 years.

ATSC President and Chief Executive Officer Dr. Edward H. Bersoff stated, “We are extremely pleased to report strong results for the third quarter.  For the second consecutive quarter, our revenues and profits have grown and we’ve generated strong cash flow.   The revenue growth represents an increase in each of our market areas.  Our third quarter new bookings reflect expanded work with the Company’s largest and longest standing customers and we are happy to continue our exceptionally strong track record of customer satisfaction. As a consequence, rather than re-competing many of our long-term contracts, several of our clients continue to provide us with quarterly continued funding on a non-competitive basis.  And as further testament to solid client relationships, our new $12 million award with PBGC was addictive to our current base of business with that customer.  As we have discussed in earlier periods, we also saw our Fannie Mae business further recover in the third quarter, and that business is now operating at comparable levels to 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 third quarter and ability to expand our year to date EBITDA margins to 11.9%, even with an increase in our investment in business development of approximately 16% in the first nine months of this year compared to the same period last year.   We will continue to invest in business development to support our long term growth objectives.  We have also improved our DSO which were at 61 days at the end of the third quarter of 2009, a drop from 67 days at the end of the second quarter of 2009 and a drop of 25 days from the end of 2008.  As a result of the strong profits and improvements in cash flow, we paid down another $6.5 million in debt this quarter.”

Dr. Bersoff concluded, “We believe our strong financial performance for the quarter provides strong momentum for sustaining our organic growth and increasing shareholder value as we end the year and enter 2010.”

Management’s Revised Outlook

Based on ATSC’s year to date profit margins, the Company is updating its EBITDA (1) guidance for 2009.  The Company is now increasing its EBITDA (1) forecast for the year to be between $12 million and $13.5 million.  The Company is reiterating its revenue guidance range of $121 million and $125 million.

Dr. Bersoff commented, “We have consistently exceeded our target EBITDA and EBITDA margins each quarter of 2009 and expect to end the year with EBITDA margins for the full year well in excess of industry norms.”

(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) Adjusted EBITDA is defined as EBITDA adjusted for one time severance expenses not expected to be reflected in the ongoing performance of ATSC.  Adjusted 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 end of this release that reconciles GAAP net income to adjusted EBITDA.
