ECS gained market share in 2011 in the Department of Defense and Federal spaces through both organic and acquisition growth. In May, ECS completed its first strategic acquisition with the purchase of OAK Management, Inc., a leading provider of marine environmental services, ship systems engineering, maritime consulting and platform acquisition management. The OAK acquisition kicked off ECS’ intention to add tactical acquisitions as a part of its long term strategy to supplement and expand upon organic growth and to build enterprise value. ECS closed out 2011 with the acquisition of Paradigm Technologies, Inc. The Paradigm transaction added approximately 200 employees to ECS’ existing 900+ employees. Paradigm also added new Defense clients for ECS, including the Missile Defense Agency, the Navy’s Program Executive Officer for Integrated Warfare Systems, the United States Marine Corps, and the U.S. Marshals Service.
In 2012, ECS completed the acquisition of iLuMinA Solutions, Inc. iLuMinA brings large-scale Enterprise Resource Planning (ERP) software implementation and infrastructure design and development to ECS’ expanding capabilities.
