ARLINGTON, Va.--(BUSINESS WIRE)--August 14, 2013--CACI International Inc (NYSE: CACI), a leading information solutions and services provider to the federal government, announced results today for its fourth fiscal quarter and full fiscal year ended June 30, 2013:

• Revenue of $912.9 million for the fourth quarter and $3.68 billion for the year
• Operating income of $67.9 million for the fourth quarter and $270.8 million for the year
• Net income attributable to CACI of $37.9 million for the fourth quarter and $151.7 million for the year
• Diluted earnings per share of $1.56 for the fourth quarter and $6.35 for the year

CEO Commentary and Outlook

Ken Asbury, CACI’s President and CEO, said, “Our fourth quarter results were in line with our guidance expectations and reflect our ability to adapt to an uncertain market. We grew revenue in our high-growth market areas of Business Systems, Cyberspace, Healthcare, and Integrated Security Solutions, and received half of our awards in the quarter from those same areas. In addition, we reduced our cost structure, which will drive efficiencies and preserve our margins. These actions position us to continue to be successful in meeting our customers’ high-priority mission requirements in an ongoing, sequestered environment.

“Since the beginning of our new fiscal year, we are encouraged that we have won a number of significant new business and recompete awards. In addition, we have strengthened our business development organization with the addition of two key executives. We will continue to execute our strategy that is focused on winning business in support of the government’s high-priority missions, delivering operational excellence to our customers, and making acquisitions that bring us new customers and new capabilities. All of this gives us the confidence to reiterate our FY14 guidance.”

Fourth Quarter Comparisons

When analyzing our performance, we believe better insight and a more meaningful comparison of our Fiscal Year 2013 (FY13) results with those of Fiscal Year 2012 (FY12) can be made by adjusting for three material one-time items that positively impacted our results last year. The one-time item that impacted our fourth quarter FY12 results, which we discussed when we released both our fourth quarter FY12 results and our FY13 annual guidance, is greater-than-expected profitability on a large fixed-price contract that generated $0.1 million in additional net income in the fourth quarter of FY12 and $7.1 million during the full year of FY12.

Results for the fourth quarter of FY13 compared with results for the fourth quarter of FY12, excluding the item described above, are shown below:

Revenue decreased 3.8 percent from revenue for the fourth quarter of FY12. Our 4.3 percent increase in direct labor was offset by a reduction of material purchases and subcontract labor. Operating income in the fourth quarter of FY13 was negatively impacted by $7 million in one-time severance and facilities-related expenses. Net income attributable to CACI in the fourth quarter of FY13 was $37.9 million, or $1.56 diluted earnings per share, a decrease of 12.3 percent over adjusted net income attributable to CACI of $43.3 million, or $1.59 adjusted diluted earnings per share, for the same period in FY12. Net cash provided by operations in the quarter was $106.9 million. (See Reconciliation of Revenue, Operating Income, Net Income, and Diluted Earnings Per Share to Adjusted Amounts on page 13.)

For a comparison of our FY13 results to FY12 results reported in accordance with generally accepted accounting principles (GAAP), see the income statement on page 7 of this release.

Fourth Quarter Awards and Contract Funding Orders

During the fourth quarter, we received awards in all ten of our markets with approximately one-half of those in our high-growth markets of Business Systems, Cyberspace, Healthcare and Integrated Security Solutions. Our contract awards were $561 million in the quarter. Approximately two-thirds of our awards in the quarter were either contract modifications or recompete wins, which assures us that we continue to serve critical missions of our customers. FY13 awards totaled $3.4 billion, led by Business Systems, C4ISR, and Intelligence. This amount also includes more than $425 million in contracts with federal government clients in the Intelligence Community.

Contract funding orders in the fourth quarter were $722 million and $3.42 billion for FY13. Our total backlog at June 30, 2013 was $6.9 billion. Funded backlog at June 30, 2013 was $1.7 billion.

We continued to expand our inventory of indefinite delivery, indefinite quantity (IDIQ) contract vehicles during the quarter by being awarded prime positions on new multiple and single award contracts, resulting in a combined total of over 160 of these vehicles. IDIQ contract vehicles support our growth plans across our ten markets and provide us the flexibility to deliver on our customers’ mission-critical requirements. Awards during the quarter included:

• A $45 million, two-year award to provide a wide range of business IT and command and control solutions to support the U.S. Navy’s SPAWAR Space and Warfare Systems Center Atlantic (SSC Atlantic). This ongoing work expands our presence in the Business System Solutions and Logistics and Material Readiness market areas.
• A $26.7 million, five-year award to provide a wide array of training and logistics support for a customer in our Integrated Security Solutions market area. This new work grows our business in that area.

IDIQ awards during the quarter included:

• An $899 million, five-year multiple award to provide Business and Force support services to the SSC Atlantic Business Portfolio. This new work is one of three “Pillar” contracts that we have been awarded, and supports the entire spectrum of non-inherently governmental solutions and services associated with the SSC Atlantic Business Portfolios. It further expands our presence in the C4ISR, Business Systems, Cyber, and Enterprise IT market areas.
• An $899 million, five-year multiple award to provide Decision Support services for the SSC Atlantic Business Portfolio. This new work, another of the three “Pillar” contracts from SSC Atlantic that we have been awarded, further expands our command and control presence, a part of our C4ISR market, as well as our presence in the Business Systems, Cyber, and Enterprise IT market areas.

Fourth Quarter Highlights

Mr. Daniels brings more than 25 years of experience in global information solutions and services, with a strong track record in building and growing profitable organizations. Mr. Jews is a senior business and healthcare executive whose over 25 years of experience includes leading organizational growth and completing successful mergers and acquisitions.

Fourth Quarter Recognition

Comparison of Twelve Months Results

As noted on page 1 of this release, we believe better insight and a more meaningful comparison of our FY13 results with those of FY12 can be made by adjusting for three material one-time items that positively impacted our results last year. These items, which we discussed when we released both our full year FY12 results and our FY13 annual guidance, are:

• A large commercial product sale that generated $12.0 million of revenue and $6.1 million of net income in the first quarter of FY12
• Greater-than-expected profitability on a large fixed-price contract that generated $7.1 million of net income during the full year of FY12
• A $0.4 million increase in net income in the first quarter of FY12 associated with a reduction in the fair value of contingent consideration related to a prior year acquisition

Results for FY13 compared with results for FY12, excluding the items described above, are shown below:

Revenue decreased 2.1 percent from adjusted revenue for FY12 primarily due to increases in direct labor being offset by a reduction of material purchases tied to the draw down in Afghanistan as well as sequestration-related reductions in other material purchases. Operating income in the second half of FY13 was negatively impacted by $10 million in one-time severance and facilities-related expenses. Net income attributable to CACI for FY13 was $151.7 million, or $6.35 diluted earnings per share, a decrease of 1.4 percent from adjusted net income attributable to CACI of $153.9 million, or $5.47 adjusted diluted earnings per share, for FY12. Net cash provided by operations in FY13 was $249.3 million. (See Reconciliation of Revenue, Operating Income, Net Income, and Diluted Earnings Per Share to Adjusted Amounts on page 13.)

For a comparison of our FY13 results to FY12 results reported in accordance with GAAP, see the income statement on page 7 of this release.
