Net obligations by fiscal year of action, from FPDS contract actions under NAICS 561621. Vendors are placed by their headquarters state in SAM.gov, not by where the work is done. Awards and orders count canonical awards with a positive net in the year; IDV vehicles are not counted. FY2026 is provisional for 120 days after it ends, and DoD withholds awards for 90 days at the source. Methodology
