Public-to-private transactions in the defence and aerospace sector continue to draw sponsor interest in the UK.

A consortium of Tinicum and Blackstone has agreed to acquire FTSE 250-listed Senior Plc in a recommended £1.275 billion all-cash offer, taking the international engineering group private.

Senior designs and manufactures high-technology components and systems for the aerospace, defence, land vehicle, and power and energy markets.

The company operates across multiple geographies and serves a blue-chip customer base in commercial aerospace, military programmes, and industrial end markets.

The offer gives the Tinicum-Blackstone consortium a platform with deep engineering capabilities and long-term demand tailwinds tied to global defence spending and aircraft build rates.

No other portfolio company acquirer was named, signalling the investors intend to operate Senior as a standalone platform within the defence and aerospace supply chain.

Goodwin advised the consortium on the debt financing and structuring of the transaction.

Completion is subject to shareholder approval and regulatory clearances.
