ARLINGTON, Va.--(BUSINESS WIRE)--August 17, 2011--CACI International Inc (NYSE: CACI), a leading professional services and information technology solutions provider to the federal government, announced results today for its fourth fiscal quarter and full fiscal year ended June 30, 2011.

Fourth Quarter Results

The following table summarizes results computed in accordance with Generally Accepted Accounting Principles (GAAP), including the positive effect on operating income, net income and diluted earnings per share of earn-out adjustments.

We are pleased to report record fourth quarter Fiscal Year 2011 (FY11) revenue of $963.2 million, an increase of 13.5 percent from the fourth quarter of Fiscal Year 2010 (FY10). The revenue increase was driven primarily by organic growth of 11.5 percent, reflecting continued growth in our C4ISR Solutions and Services, Cyber Solutions, Enterprise IT Management, and Program Management and SETA Services core competencies.

Pro Forma Fourth Quarter Results

In FY10, we completed two domestic acquisitions with acquisition-related contingent consideration, or earn-outs, which represent potential additional purchase consideration based on the acquired company’s performance post-acquisition. The fair values of the expected earn-outs were recorded as liabilities on the balance sheet as of each acquisition date, and are re-measured each quarter, with any change in the fair values of the liabilities reflected in the income statement. In the fourth quarter of our FY11, the liabilities decreased $8.2 million, with a corresponding increase to operating income, due to reductions in the fair values of the earn-out liabilities. In the fourth quarter of FY10, the liabilities decreased, and operating income increased, by $2.7 million. To provide a comparison of our results excluding these earn-out adjustments, pro forma results for the fourth quarter of FY11 and FY10 are shown below.

Pro forma operating income grew 36.3 percent over the prior year period to a record $69.9 million, driven by strong growth in direct labor and continued cost control. We also benefitted from a lower than expected tax rate. Pro forma net income for the fourth quarter of FY11 was a record $40.9 million, or $1.28 pro forma diluted earnings per share, an increase of 44.8 percent over pro forma net income of $28.3 million, or $0.91 pro forma diluted earnings per share, for the same period in FY10. Net cash provided by operations in the quarter was $79.1 million. (See Reconciliation of Operating Income, Net Income and Diluted Earnings Per Share to Pro Forma Amounts on page 14.)

CEO Commentary and Outlook

Paul Cofoni, CACI's President and CEO, said, "In Fiscal 2011, we delivered on our financial goals of mid- to high-single-digit organic revenue growth and double-digit earnings growth. We achieved record results in revenue, operating income, EPS, and cash flow, and our strong funding orders for the year – the highest in CACI’s history – give us confidence that we will sustain our top and bottom line growth into the future. Our Board of Directors has replaced our $175 million share repurchase authorization with an authorization to repurchase up to 4 million shares, and we fully expect to implement a corresponding repurchase plan which is expected to deliver further value to our shareholders.”

Mr. Cofoni added, “Our strong performance results are directly attributable to our growth strategy to pursue high-priority, well-funded markets; our operational excellence; our success in capitalizing on opportunities in emerging markets; and our ability to compete for and win new business. We believe the government is committed to achieving a balanced deficit reduction that will not put national security at risk, and we continue to see growth opportunities and funding in our strategic focus areas of defense, intelligence, homeland security, cybersecurity, and IT modernization and transformation of government.

"Persistent threats to our national security continue to create strong demand for CACI's innovative C4ISR solutions and services, and federal budgetary constraints are increasing the demand for our IT modernization and government transformation capabilities that can reduce costs, increase productivity, and provide improved service to taxpayers. Our momentum is accelerating in the high-growth cyber arena with FY11 cybersecurity awards totaling over $120 million while our acquisition of Pangia Technologies and planned purchase of Paradigm Holdings offer additional significant cybersecurity capabilities. We also expect growth as a result of our significant inroads into the healthcare IT market in FY11, including our recent prime position on the Department of Veterans Affairs $12 billion Transformation Twenty-One Total Technology IDIQ contract.

“We are celebrating our 50^th year of serving clients with excellence, delivering value to our shareholders, and providing opportunities for our diverse employee team to be the best. Our Fiscal Year 2011 achievements and forward momentum give us the confidence to raise our guidance for Fiscal Year 2012. We look forward to another year of meeting our financial goals while creating new value for our clients and our shareholders."
