QinetiQ Group plc (“QinetiQ” or the “Company”) is pleased to announce that on 30 November 2022 it completed the acquisition of Air Affairs, a leading Australian defence services company in air threat representation, test and evaluation (T&E), unmanned targets and mission rehearsal.

The acquisition of Air Affairs is an exciting step to further build and accelerate QinetiQ in Australia,
growing our T&E and threat representation capability globally. The transaction represents another
strategically significant milestone for QinetiQ following the completion of the Avantus acquisition in the
US in November. We are on-track to deliver our long-term strategy to build a world-leading defence and
intelligence company providing mission-led, disruptive innovation to our customers across the US, UK,
Australia and other customers around the world.

Since the initial announcement of the acquisition, Air Affairs has continued to perform well. Our
integration plan has been fully prepared, and we are now focused on executing the integration to create
opportunities for our customers and employees whilst delivering attractive financial returns.
Steve Wadey, Group Chief Executive Officer of QinetiQ, said:

“I am delighted that we have completed the acquisition of Air Affairs. The acquisition further strengthens
our long-term strategic partnership with the Australian Defence Force and underpins our market-leading
position in T&E and air threat representation globally. The acquisition is an excellent strategic and cultural
fit that grows our revenues in Australia by 40%, and further reinforces the focus of our growth strategy
on our six distinctive offerings in our three home countries, delivering mission-critical solutions for our
customers.”
