Advent is preparing to invest up to $1bn in defence technology, as the private equity firm looks to expand its exposure to next-generation security and aerospace assets, according to sources cited by Bloomberg.

The strategy will focus on companies developing advanced defence technologies, reflecting growing demand driven by rising geopolitical tensions and increased global defence spending.

The move builds on Advent’s significant track record in the sector, having invested more than $15bn in defence assets since 2020, including positions in Cobham and Ultra Electronics.

At the same time, the firm is exploring a potential $4bn sale of its Ultra Maritime business, highlighting ongoing portfolio optimisation alongside new capital deployment.

The renewed focus on defence technology comes as private equity firms increase allocations to the sector, supported by long-term government spending commitments and heightened security priorities.

Rising global conflicts, including in the Middle East, have further accelerated investor interest in defence and security-related assets.

Advent’s strategy reflects a broader shift across private equity, with firms seeking exposure to resilient, strategically important sectors that benefit from structural demand.
