MCLEAN, VA – (BUSINESSWIRE) – March 12, 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 fourth quarter and fiscal year ended December 31, 2008.

Fourth Quarter Results

ATSC reported revenue of $30.9 million for the fourth quarter of 2008.  Revenue for the fourth quarter decreased by 2% over fourth quarter revenue of $31.5 million in fiscal year 2007.  The revenue decline was primarily driven by underperformance in the Company’s commercial business areas.  Quarter over quarter revenue from commercial contracts decreased by 19% to $6.3 million.  Quarter over quarter revenue from government contracts increased by 2% to $24.5 million.

Operating income for the fourth quarter of 2008 was $2.6 million and the net income for the quarter was $785,000, or $0.03 per diluted share, compared to an operating loss of $32,000 and a net loss of $259,000, or loss of $0.01 per diluted share for the fourth quarter of 2007.

EBITDA(1) was $3.4 million for the fourth quarter of 2008, resulting in an EBITDA margin of 11.1%, an increase of 21.4% over 2007 fourth quarter EBITDA (2) of $2.8 million or an EBITDA margin of 8.9%.

Backlog as of December 31, 2008 was $178.4 million, of which $53.1 million was funded.  Day’s sales outstanding were 86 at the end of the fourth quarter of fiscal year 2008.  As of December 31, 2008, ATSC’s balance sheet included debt of (i) $32.6 million on its revolving credit facility, down from $35.8 million at September 30, 2008 and (ii) approximately $4.5 million in promissory notes related to the acquisitions of Potomac Management Group, Inc. and Number Six Software, Inc., down from $5.2 million at September 30, 2008.  Additionally, the balance sheet included $45.9 million in stockholders’ equity.

Full Fiscal Year 2008 Results

ATSC reported revenue of $131.5 million for the fiscal year ended December 31, 2008.  Revenue for the year increased by 23.0% over the revenue for fiscal year 2007.  Acquisitions occurring in the second half of fiscal year 2007 strongly influenced year over year revenue growth.

As reported in the ATSC third quarter 2008 earnings release, the Company incurred a $56.8 million, non-cash goodwill and intangible asset impairment charge.  The impairment resulted primarily from an updated outlook for businesses acquired during 2007, leading to an adjustment of the estimated fair value of goodwill and certain intangible assets.

Including the impact of the impairment charge, the operating loss for the year was $51.1 million and net loss for the year was $49.8 million, or $2.35 per diluted share, compared to operating income of $1.1 million and a net loss of $6.5 million, or $0.35 per diluted share for fiscal year 2007.

EBITDA (1) was $12.2 million for 2008, resulting in an EBITDA margin of 9.3% and an increase of 50.6% over adjusted 2007 EBITDA (2).  As previously reported, the Company incurred one-time severance costs totaling $890,000 in the third quarter of 2008 related to the termination of three senior executives.  The exclusion of those expenses produced an adjusted EBITDA (3) of $13.1 million for 2008, resulting in an adjusted EBITDA margin of 9.9% and an increase of 61.7% over 2007 EBITDA.  The 2007 EBITDA was $8.1 million for the eleven and one-half month period ending December 31, 2007, which resulted in an EBITDA margin of 7.6%.

The net loss for fiscal year 2008 was driven by the $56.8 million writedown of goodwill and intangibles.  Net income adjusted for the impairment charge and associated tax benefit (4) was $2.0 million, or $0.09 per diluted share.

Fourth Quarter New Bookings

Fourth quarter net new bookings totaled approximately $1 million.  Subsequent to the end of the quarter, the Company booked several new awards, the largest of which were a $11.3 million contract with the Federal Election Commission and a $6 million contract with the Defense Security Service.

2008 Highlights and Management Comments

Major ATSC highlights for 2008 included:

§ Maintaining above industry average EBITDA margins in excess of 9% for each quarter and the full year;

§ Paying down outstanding debt by over $11 million in 2008, representing nearly 25% of our total borrowings;

§ Retiring 92% of our warrants;

§ Moving into a new headquarters facility and upgrading our internal IT infrastructure, saving over $1.5 million in annual costs; and

§ Expanding the depth of the management team with the addition of a highly experienced Chief Operating Officer.

ATSC Chairman and Chief Executive Officer Dr. Edward H. Bersoff commented, “While 2008 was a year of mixed results for us, I’m very pleased with what we were able to accomplish in a period of significant economic instability.  We were able to exceed our target EBITDA margins of 9% and deliver EBITDA of $12.2 million for the year and adjusted EBITDA of $13.1 million, well within our guidance for the year, and even within EBITDA guidance we had provided earlier in the year prior to making adjustments related to weaknesses we subsequently experienced in revenue.   Our revenue results for the year were within our guidance; however, our inability to deliver strong organic growth was due mostly to underperformance in our commercial contracts.  Our government business remained stable throughout the year and we are encouraged by our two recent wins, one with the Federal Election Commission, representing our continued ability to win all our recompetes, and the other with the Defense Security Service, representing our ability to penetrate a new client sector in the growing areas of cybersecurity and biometrics.”

ATSC Executive Vice President and Chief Operating Officer George Troendle added, “We remain optimistic about 2009 performance and our market positions in light of the challenging economic environment and priorities of the new presidential administration.  Our work with two of our biggest customers, the Department of Housing and Urban Development (“HUD”) and Fannie Mae, performed as we expected in 2008 and with no significant downturns related to the housing crisis.   In fact, we won new business at HUD last year in response to the Housing and Economic Recovery Act of 2008 and one of our mortgage backed-security (“MBS”) products is handling approximately 25% of the Federal Reserve Bank’s transaction volume related to its $500 billion MBS repurchase program.  We will continue to monitor our commercial business, as we did in 2008, to keep costs in line with top-line performance and make investments where we see the potential for growth.”

ATSC Executive Vice President and Chief Financial Officer Pamela Little further commented on the financial performance, “As a result of our strong profitability, we were able to pay down over 25% of our borrowings over the course of the year and therefore maintain a healthy relationship with our lenders in the midst of the credit crisis.  Furthermore, while we would have liked to have seen stronger organic growth over last year, we were still able to deliver higher than industry average operating profits and were very pleased in our ability to increase EBITDA margins by 170 basis points over last year.”

Management’s Outlook

The Company’s previously issued financial guidance for 2009 is for total revenues of between $129 to $135 million and EBITDA (1) between $11.5 and $13.0 million.

“While our guidance for the full year of 2009 represents modest organic growth over 2008, we are encouraged by several positive trends that we believe will offset some of the revenue weaknesses we experienced in 2008, and we anticipate a return in quarter over quarter growth in 2009, unlike the declines we experienced in 2008.  New business and building our backlog over the year will remain one of our top priorities in 2009,” concluded Dr. Bersoff.

(1) EBITDA is a non-GAAP measure that is defined as GAAP net income plus other expense, interest expense, income taxes, depreciation and amortization, and impairment charges.  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) 2007 EBITDA – Earnings before interest, taxes, depreciation and amortization adjusted for one time items not expected to be reflected in the ongoing performance of ATSC and related to severance expenses, start-up Sarbanes-Oxley compliance costs and other transaction-related one time expenses.

(3) Adjusted EBITDA is defined as EBITDA adjusted for one time severance expenses not expected to be reflected in the ongoing performance of ATSC.  Please refer to the table at the bottom of the statement of operations in this release that reconciles GAAP net income to adjusted EBITDA.

(4)  Net income adjusted for the impairment charge and associated tax benefit is a non-GAAP measure that is defined as GAAP net loss plus the impairment charge and less the associated tax benefit.  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.
