Should federal government contracts increasingly utilize fixed-price and outcome-based models?
Barbara Supplee has taken over as CEO of Serco North America, succeeding Michael LaRouche, who departed to lead a KBR spinoff. The leadership transition comes as the government services firm navigates a shift toward performance-based contracts.
Why it matters
The appointment follows an intense period of turnover for the firm, which operates under $2 billion in annual revenue and maintains large-scale service contracts for federal agencies. Supplee must now stabilize the leadership team while executing a strategy built on commercial tech partnerships.
Serco North America, which reported $2 billion in 2025 revenue and manages a 10,000-employee workforce, has cycled through three CEOs in the last 18 months. The firm previously expanded its scale through a $327 million acquisition of a Northrop Grumman training business.
