CACI Awarded Two Task Order Contracts Totaling $86 Million to Support U.S. Army’s Software Engineering Center

Providing World-Class System and Software Engineering to Enhance Battlefield Management Systems, Increase Troop Safety and Support

CACI International Inc (NYSE:CACI) announced today it has been awarded two task order contracts totaling $86 million to provide software support and engineering services to the U.S. Army’s Communications-Electronics Command (CECOM) Software Engineering Center (SEC). These two-year (one base plus one option year) task orders were awarded under the CECOM SEC Software and Systems Engineering Services Next Generation (SSES NexGen) program. Originally awarded during CACI’s first quarter of its Fiscal Year 2015, ending September 30, 2014, these contracts represent both new and continuing work and expand CACI’s presence in its C4ISR (Command, Control, Communications, Computers, Intelligence, Surveillance, and Reconnaissance) and Logistics and Material Readiness market areas.

The CECOM SEC’s mission is to ensure the highest level of software readiness for Army C4ISR and logistics systems. The two SEC task orders include a $63 million System and Software Engineering Support Services (SSES) award, new work for CACI, to support the C3T Fires Division in sustaining the reliability and interoperability of fielded fire support systems, which help warfighters acquire targets and deliver the necessary firepower. Additionally, CACI won a $23 million Command and Control Software Support Services (C2S3) contract to continue supporting the C3T Mission Command Division in developing and sustaining systems that give soldiers and commanders accurate overviews of the battlefield.

With a track record of over 20 years of high-quality support for CECOM, CACI provides in-depth knowledge of the customer’s environment and requirements that ensure successful and effective project execution. CACI also offers world-class credentials in systems engineering and software lifecycle support. Its entire U.S. Operations have been appraised at Maturity Level 3 of the Capability Maturity Model Integration for Development (CMMI®-DEV), assuring CECOM its solutions meet industry-recognized levels of excellence.

John Mengucci, CACI’s Chief Operating Officer and President of U.S. Operations, said, “CACI offers proven subject matter expertise, project management skills, and recognized CMMI credentials to provide the high-value software development, sustainment, and acquisition solutions our Armed Forces need to ensure system readiness, information dominance, and ultimately, the safety of our troops on the battlefield.”

According to CACI President and Chief Executive Officer Ken Asbury, “These two awards on the SSES NexGen vehicle continue CACI’s record of success supporting the U.S. Army’s Software Engineering Center. In addition to enhancing our business in our C4ISR and Logistics and Material Readiness market areas, this work gives us the opportunity to rapidly deliver next-generation software that fills a critical need – providing our troops with an operational advantage.”
