Insight
Over the last 10 years, PSC R799 obligated $36.30 billion across 87,126 awards, with an average award value of $416.6K, indicating a high-volume, moderately fragmented spend base. Top vendor obligations are concentrated among a small set of firms, but the leading vendor accounts for only $1.58 billion, or about 4.4% of total obligations, so spend is not highly concentrated at the top. Several vendors appear multiple times with different CAGE codes or naming variations, including Booz Allen Hamilton and Deloitte, suggesting the need to normalize vendor identity before interpreting supplier concentration.
