Summary
Blackstone and Tinicum have reached an agreement to acquire Senior, a publicly listed UK aerospace and defence engineering company, in a transaction valued at approximately £1.4 billion. The consortium of US investment firms will acquire the FTSE 250-listed group at 300p per share, inclusive of a planned dividend of 2.15p per share, according to announcements made on Tuesday.

Senior, a major supplier to the aerospace and defence industries, becomes the latest London-listed industrial manufacturing company to be taken private by large alternative asset managers. The transaction represents a significant shift in ownership of critical UK supply chain infrastructure to American private capital, marking what industry observers have characterized as a loss to the London stock exchange of a substantial defence and engineering asset.

The board of Senior has formally recommended the offer to shareholders, indicating that negotiations between the parties have been concluded and the transaction is progressing toward completion pending customary shareholder approval and regulatory clearances. Tinicum, described as a New York-based private investment firm, is partnering with Blackstone, one of the world's largest alternative asset managers, in the acquisition vehicle.

The transaction reflects sustained institutional investor interest in aerospace and defence supply chain consolidation, particularly as defence spending accelerates globally and supply chain resilience becomes a strategic priority for governments and prime contractors. The deal also underscores the competitive position of large, well-capitalized alternative asset managers in acquiring mid-market industrial assets in the current investment environment.
