Redwire is a space and defense technology company that designs and builds hardware for spacecraft, space infrastructure, and military drones. The company operates through two roughly equal segments: Space and Defense Tech. The Space segment offers five spacecraft platforms across different orbits, large space infrastructure products including the Roll-Out Solar Array (ROSA, a deployable solar power system with flight heritage on the ISS) and the International Berthing and Docking Mechanism (IBDM), and a microgravity drug development business that operates ISS payloads for pharmaceutical partners like Bristol Myers Squibb and Eli Lilly via a subsidiary called SpaceMD. The Defense Tech segment — added via the June 2025 acquisition of Edge Autonomy — makes the Stalker UAS (a fuel-cell-powered drone used by the U.S. Marine Corps) and the Penguin series of fixed-wing and VTOL drones used by Ukraine and other allied militaries, as well as optical camera payloads and space-qualified avionics. Customers include U.S. and allied national security agencies, commercial space companies, and civil agencies like NASA and ESA, with roughly 42% of revenue coming from international customers. The Space segment runs on long-duration, fixed-price development contracts recognized on a percentage-of-completion basis, carrying margin risk from cost overruns. The Defense Tech segment is more production-oriented, with repeat fleet orders creating a more predictable revenue stream. Redwire has grown largely through M&A, completing 11 acquisitions since its 2020 founding, and is pursuing contracts under the U.S. Golden Dome missile defense initiative.
