Triad National Security, LLC received more money from the Department of Energy than any other recipient in FY2026 (data still posting): $5.5B in obligations. Ranked by what the Department of Energy obligated to each recipient in FY2026 (data still posting), so the list is about this agency's money rather than a contractor's overall size. Combined corporate families count once. Computed

Ranked from USASpending records. FY2020 to FY2026 are loaded. FY2026 ended on September 30, 2026, and its records are still posting, so each total is shown beside the same name's FY2025 figure, with no percentage change. Rank vs FY2025 is each name's change in position from FY2025, and positions can still move as late FY2026 records post; a dash means the name was not in FY2025's data.
