Net income of $33 million and diluted earnings per share of $1.33

Received contract funding orders of $1.3 billion

Reiterates FY14 annual guidance

ARLINGTON, Va.--(BUSINESS WIRE)--October 29, 2013--CACI International Inc (NYSE: CACI), a leading information solutions and services provider to the federal government, announced results today for its first fiscal quarter ended September 30, 2013.

CEO Commentary and Outlook

Ken Asbury, CACI’s President and CEO, said, “Our performance in the first quarter is in line with our expectations and demonstrates our ability to adapt to the changing conditions in our marketplace, which continues to be impacted by uncertainty surrounding budgetary constraints and sequestration. We continued implementing our three-part growth strategy by winning a significant amount of business and securing solid contract funding, both at levels comparable to last year; driving operational excellence; and executing on the first priority for the deployment of our capital, our mergers and acquisition program, culminating in the announcement in early October of our intent to purchase Six3 Systems, Inc. Our progress in the quarter gives us the confidence to reiterate our FY14 annual guidance.

“We expect that the acquisition of Six3 Systems will have a positive impact on the balance of our FY14 and further differentiate CACI in our key market areas of cyber, C4ISR, and intelligence. The addition of Six3 Systems will further position CACI as a leader in digital signals processing and innovative cyber solutions for our national security customers.”

First Quarter Results

Revenue for the first quarter of Fiscal Year 2014 (FY14) decreased 7.2 percent compared to the first quarter of Fiscal Year 2013 (FY13). The decrease in revenue in the first quarter of FY14 was driven primarily by the as expected reduction of material purchases and subcontract labor resulting from the drawdown in Southwest Asia and federal government budget-related reduction activities. The decrease in operating income in the quarter was due to the as expected $7.0 million year-over-year first quarter decline on a fixed-price contract, and $1.7 million of acquisition-related expenses for Six3 Systems, Inc., partially offset by cost reduction actions initiated in FY13. The fixed-price contract is expected to generate a normal level of profitability over its life. Net income attributable to CACI in the first quarter was $33.0 million, or $1.33 diluted earnings per share, a decrease of 7.6 percent from net income attributable to CACI of $35.7 million, or $1.49 diluted earnings per share, for the first quarter of FY13. The greater decrease in diluted earnings per share is due to the dilutive effect of our convertible notes, which mature in May 2014. Net cash provided by operations in the quarter was $27.3 million.

Additional Financial Metrics

First Quarter Awards and Contract Funding Orders

Our contract awards were $1.8 billion in the quarter, slightly higher than the year earlier period, and we received awards in all ten of our markets. Almost one-third of our awards in the quarter were new business. Some of our new business and recompete contract awards during the quarter included:

• Two prime contracts by the U.S. Army, totaling $237 million, to support the Warfighter Information Network—Tactical with comprehensive fielding, sustainment, and maintenance of satellite terminals to provide a full range of encrypted and open communications. This new work expands our growth in our C4ISR and Logistics and Material Readiness market areas.
• A $75 million, five-year award by the U.S. Air Force to sustain Expeditionary Contingency Medical Materiel Support Services. This award continues work performed in support of medical logistics services in the U.S. and the Pacific, and expands growth in our Healthcare and Logistics and Material Readiness market areas.
• A $45 million, five-year award to support the Defense Information Systems Agency (DISA) Multinational Information Sharing Program Management Office (MNIS PMO), won under the DISA Encore II contract vehicle. This new work further advances our growth in our Enterprise IT market area.
• A $40 million, two-year award to support the U.S. Army Intelligence and Information Warfare Directorate’s quick reaction capability to meet emerging intelligence requirements. This ongoing work continues our growth in our C4ISR market area.
• A $26 million, three-year award to provide healthcare facilities support to the Air Force Medical Support Agency’s Health Facilities Division. This ongoing work reinforces our presence in our Healthcare market area.
• A $22 million, two-year contract to provide engineering subject-matter expertise for Department of Defense Mobile Electric Power energy sources. This work is in our Integrated Security Solutions market area.

Contract funding orders in the first quarter were $1.3 billion. Our total backlog at September 30, 2013 was $7.8 billion. Funded backlog at September 30, 2013 was $2.1 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 award contracts, resulting in a combined total of approximately 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. IDIQ awards during the quarter included:

• A $1.1 billion, six-year multiple award to continue providing litigation support services to the U.S. Department of Justice and other federal agencies on the Mega 4 contract. This ongoing work reinforces our strong presence in our Investigation and Litigation Support market area.
• An $899 million, five-year multiple award to support Integrated Cyber Operations services for the Space and Naval Warfare (SPAWAR) Atlantic Business Portfolio. This new work is the fourth of five “Pillar” contracts that we have been awarded, and provides full system lifecycle support of the SPAWAR Atlantic Business Portfolio. It further expands our presence in the Cyberspace market.

First Quarter Highlights

• Continuing CACI’s role as a top thought leader in national security, we announced the release of Combating Asymmetric Threats: The Interplay of Offense and Defense, a report from the seventh symposium in the Asymmetric Threat symposia series co-sponsored by CACI, the U.S. Naval Institute, and the Center for Security Policy. The report considers how the dynamics of offensive and defensive measures shape the character, conduct, and outcomes of asymmetric conflicts.
• David M. Wennergren joined CACI in August as Vice President within our Enterprise Technologies and Services business group, heading opportunity management and customer delivery practices. Prior to this, he served as Assistant Deputy Chief Management Officer in the Office of the Secretary of Defense. He brings a proven track record of successfully leading large and complex change management and information management/information technology projects across the U.S. federal government.
• CACI Chairman of the Board Dr. J. Phillip London released his new book, Character: The Ultimate Success Factor. Based on Dr. London’s personal, corporate, and military experiences, with real-life examples, the book provides an insightful and practical demonstration of how character is the key to long-term success.

Subsequent Events since October 1, 2013

• On October 9, 2013, we announced our intent to acquire Six3 Systems, Inc. for $820 million in cash. The largest acquisition in CACI’s history, Six3 has approximately 1,600 new employees and its Calendar Year 2013 revenue is expected to be approximately $470 million. Six3 will add distinctive cyberspace, C4ISR, and intelligence capabilities to our solutions and services, deepen our current customer base, and bring us new customers. We expect the acquisition to expand our addressable market by approximately $15 billion and be at least 5 percent accretive to GAAP earnings per share and at least 10 percent accretive to diluted adjusted earnings per share in Calendar Year 2014. The transaction is anticipated to close during our fiscal second quarter, ending December 31, 2013.
