CACI Issues Guidance for its Fiscal Year 2013

FY 2013 diluted EPS projected to be $6.60 to $6.90

FY 2013 net income projected to be $160 million to $167 million

FY 2013 revenue projected to be $3.8 billion to $4.0 billion

FY 2012 revenue and net income guidance reiterated

ARLINGTON, Va.--(BUSINESS WIRE)--June 6, 2012--CACI International Inc (NYSE: CACI), a leading professional services and information technology solutions provider to the federal government, issued its guidance for its Fiscal Year 2013 (FY13), which begins July 1, 2012, and reiterated its Fiscal Year 2012 (FY12) revenue and net income guidance.

Guidance for Fiscal Year 2013

For FY13, we expect revenue to be between $3.8 billion and $4.0 billion. We expect net income to be between $160 million and $167 million and that diluted earnings per share (EPS) will be between $6.60 and $6.90. We expect that operating cash flow for the year will be approximately $225 million. FY13 guidance includes the effect of the new four million share repurchase program announced today but does not include any impact from future acquisitions.

We would like to remind investors that, when comparing our FY13 net income guidance with our FY12 net income, two material one-time events occurred in FY12 that positively impacted our results. The first one-time event was a large commercial product sale that generated $6 million of net income. The second one-time event was the greater-than-expected profitability on a large fixed price contract, which generated $7 million in additional net income.

The table below summarizes our FY13 guidance ranges and represents our views as of June 6, 2012:

Commentary

Paul Cofoni, CACI’s President and Chief Executive Officer, said, “We are pleased to inform our investor community that CACI’s FY13 guidance reflects our confidence in delivering positive revenue and earnings growth. Our rigorous and comprehensive strategic planning process gives us great confidence in our FY13 guidance.

“Our FY13 guidance reflects both market realities and our belief in the company’s capacity to continue to grow. We see many opportunities in our specific markets and core capabilities to maintain leading performance despite industry headwinds. For FY13, we expect low-to-mid single-digit growth in revenue and mid-to-high single-digit growth in net income. We are confident that direct labor growth, the most important driver of our bottom-line performance which has contributed to our improved operating margin, will continue for the balance of this fiscal year and into FY13. This confidence is driven by our highest ever inventory of submitted proposals, more than 400 firm open hiring requisitions, strong funded backlog, and our expectation that contract awards will exceed a record $4 billion in FY12.

“With our large addressable market, CACI is well positioned to meet the demands of the government’s highest priorities and expand into additional robust growth areas. Our innovative solutions and excellent program performance have established trusted business relationships in which our clients know they can rely on CACI to serve them in achieving their critical missions supporting our nation’s security and enhancing government services.

“We remain optimistic in our agility and competitiveness in the high-priority markets of defense, intelligence, homeland security, and government transformation, with the expectation of higher growth opportunities in transformation, cyberspace, healthcare IT, and Special Operations in FY13.”
