About the company
Existx, Inc., a for-profit corporation based in Arlington, Virginia, holds a $151 billion multiple-award Indefinite Delivery Indefinite Quantity (IDIQ) contract with the Missile Defense Agency as prime contractor, awarded December 29, 2025, with no set-asides and full-and-open competition posture. The company operates predominantly as a prime (67% of recent awards) and has begun execution with minimal task orders to date.
Existx's federal footprint is nascent — three awards across two defense agencies in calendar year 2025. The Missile Defense Agency anchors both volume and dollars through the SHIELD (Scalable Homeland Innovative Enterprise Layered Defense) IDIQ, a ten-year vehicle extending through December 28, 2035, structured to procure integrated, multi-domain defense systems across air, missile, space, cyber, and hybrid threat domains. The contract scope encompasses research and development, prototyping, systems engineering, weapon design, production, test and evaluation, cybersecurity, and modernization efforts, leveraging artificial intelligence, machine learning, digital engineering, and open systems architectures. An initial $500 delivery order was placed on the same award date. Existx also subcontracts to Georgia Tech Applied Research Corp on a Department of the Air Force cybersecurity and cryptographic support task under Global Lightning and Hawkeye programs, providing subject matter expertise up to Top Secret/Sensitive Compartmented Information classification levels and supporting Authority to Operate (ATO) certification.
Award concentration sits entirely with DOD customers — the Missile Defense Agency (2 awards, $500 combined potential value) and the Department of the Air Force (1 award). Work is categorized under Research and Development in Physical, Engineering, and Life Sciences (2 awards) and Engineering Services (1 award), with primary PSC coding in National Defense R&D Services. Performance occurs in Huntsville, Alabama, with task orders issued across multiple classification levels requiring facility clearances. Combined dollars obligated ($1.5 million) substantially exceed the stated $500 combined potential value, likely reflecting obligated funding against the SHIELD IDIQ ceiling or initial mobilization costs. Recompete exposure does not arise within twenty-four months.
