Barbara Supplee, just two months into her role as Serco's North America CEO, says the planned acquisition will add specialized engineering and technology expertise.
Less than two months into Barbara Supplee’s tenure as CEO: Serco Group's North American subsidiary is buying QinetiQ's U.S. subsidiary to bulk up its defense, space and technology portfolios.
Serco Inc. said Thursday it has agreed to acquire QinetiQ’s U.S. business in a transaction being valued at $292 million, inclusive of the $232 million purchase price and a $55 million acquired tax benefit. All parties involve anticipate closing the agreement in the first quarter of 2027.
During a conference call with U.K. investors Thursday, Supplee said Serco Inc. is eyeing this move as expanding across four service areas: program and acquisition support, design and delivery, operations and technology, and data and digital.
Serco Inc. is also pushing to grow its relationships with Space Force, the Army and Navy with this acquisition.
“[QinetiQ US] brings specialist expertise and technologies that broaden what we can offer our customers,” Supplee told analysts. “Our customers increasingly need partners that can bring together technology, engineering expertise, and operational delivery to solve more complex mission requirements.”
Take for instance the Proliferated Warfighter Space Architecture, the Space Development Agency’s network of military satellites for providing communications and missile tracking to operators.
Supplee described QinetiQ US' role on that program as supporting the development and delivery of PWSA, ranging from acquisition through launch and into operations. QinetiQ US secured that five-year, $224 million systems engineering and technical assistance contract in 2023.
“Engineers help the U.S. government determine the capability it needs, support acquisition, integrate systems supplied by multiple organizations, and help make the overall constellation operate as one,” Supplee said. “It is complicated, highly technical work, and is a good illustration of the type of specialist capability QQUS brings to Serco.”
A second example Supplee brought up regards the Tethered Aerostat Radar System, an airborne platform designed to provide persistent surveillance over U.S. borders by carrying radar tech and sensors.
QinetiQ US is the lead operations and maintenance contractor for that program with Customs and Border Protection under a potential five-year, $170 million award also booked in 2023.
“QQUS is not simply operating the equipment – It also helps modernize the sensors, integrate the data, automate the system, combining engineering, software, advanced sensing, and the operational delivery,” Supplee said.
With QinetiQ US in its fold, Serco Inc. is touting pro forma 2027 revenue of $2.5 billion to represent one-third of global sales and half of the parent company’s profit profile. Serco Inc. expects QinetiQ US’ financial contribution for 2027 to include $370 million in revenue on $21 million in operating profit.
QinetiQ US is also bringing 800 employees to Serco Inc., which estimates its current workforce size as at around 10,000 people. That translates to approximately one-fifth of Serco Group’s global workforce.
Over the past decade, Serco Inc. has acquired several defense-focused businesses as part of an ongoing push to further build out its presence across that customer set and increase the mix of technology-intensive work.
Serco Inc.’s most recent move on that front centered on the Northrop Grumman mission training and satellite ground network communications business, which was purchased for $327 million in 2025.
For the QinetiQ Group PLC parent, the agreement to sell its U.S. business marks the second time that the U.K.-headquartered defense technology company has wound down its presence on these shores.
QinetiQ sold its U.S. services business to Vencore for $165 million in 2014, but kept the product unit that included robotic systems.
Then in 2022, QinetiQ ramped up its U.S. presence again with the acquisition of Avantus Federal to pursue a strategy centered around the trilateral security arrangement commonly called AUKUS – Australia, the U.K. and U.S.
Fast forward to now: the agreement with Serco Inc. resulted from a strategic review QinetiQ first announced in May. QinetiQ described the U.S. business as representing 15% of its overall revenue profile and experiencing challenges associated with the Trump administration’s scrutiny of government services contracts and other market headwinds.
QinetiQ sold its U.S. federal IT services unit to V2X in the fall of 2025 in an effort to further hone a portfolio that is now moving to Serco Inc.
What will be different now for the QinetiQ US business slated to join Serco Inc.?
“We have already identified cost synergies from the transaction, but for me, the most important point is what it does for competitiveness,” Supplee said. “In the U.S. market, scale matters. A lower cost base and a larger platform give QQUS greater flexibility when competing for work while protecting returns. That should make the business more competitive and better positioned to grow.”
