MCLEAN, Va., August 17, 2026--(BUSINESS WIRE)--BigBear.ai (NYSE: BBAI), a specialized defense and security technology company providing mission-ready AI, today announced the appointment of retired U.S. Army Lt. Gen. Sean A. Gainey to its Board of Directors, effective August 13, 2026. Gainey joins the Board after a 36-year Army career in which he helped define the Joint Force's modern counter-drone approach and later commanded JTF-Gold, Golden Dome's operational arm. "General Gainey's experience, expertise and operational insights make him a very valuable addition to the BigBear.ai Board," said Peter Cannito, Chair of the Board of Directors of BigBear.ai.
