Questions

Who is the Department of Energy's biggest contractor in FY2023?
National Technology & Engineering Solutions of Sandia, LLC, with $4.7B obligated in FY2023. Second is Triad National Security, LLC at $4.6B.
Where does this ranking come from?
It is computed from USASpending.gov award records, which are U.S. government works and in the public domain. Each figure is the total the Department of Energy obligated to that recipient in FY2023. TheFiscalFinder does the ranking; the underlying figures are the government's own.
How many recipients are shown?
The top 100 for FY2023. Each row opens that recipient's own page, where the same money is broken out by year, by counterparty and by place.
Does a high position mean anything is wrong?
No. This is a description of where public money went in FY2023, computed from public records. It is not an allegation about anyone on it.

Why the labels? The graph is only worth anything if the links are trusted. Facts taken straight from a federal filing are ✓ from source; figures we calculate are ≈ computed; links we infer (corporate parents, districts, competitors, connections between records) are ≈ inferred, worded carefully, never asserted as fact and never a claim that one thing caused another.
