Senior Shares Surge After Multiple Takeover Approaches
Shares in UK engineering group Senior climbed more than 20% on Friday after the company revealed it had received five separate takeover proposals in recent months. Private equity firm Advent International confirmed it is one of the interested bidders.
The takeover interest first emerged in January when Senior rejected an initial offer, saying it significantly undervalued the business. The same unnamed bidder later returned with two improved proposals, both of which were also turned down.
Fresh All-Cash Bids Now Under Review
Senior, which supplies key aircraft components to Boeing and Airbus, said it subsequently received two additional all-cash bids from other parties in February. These new proposals are currently under review by the board.
Advent International stated it has until 27 March to decide whether to submit a formal offer under UK takeover regulations. Neither Senior nor Advent disclosed any potential deal valuations.
Stock Hits Seven-Year High on Bid News
Following confirmation of the takeover interest, Senior’s share price jumped as much as 22.5% to 315.5 pence, its highest level in over seven years and the biggest daily gain among London-listed stocks. The surge lifted the company’s market value to more than £1.32 billion.
Senior said it released details of the bids without the consent of the potential acquirers. Analysts suggested the disclosure may strengthen the company’s position in negotiations by highlighting its strategic value.
Aerospace Deal Activity Accelerates
Mergers and acquisitions in the aerospace supply chain have accelerated as major manufacturers seek tighter control over production networks. In December 2025, Boeing completed its $4.7 billion acquisition of Spirit AeroSystems, while Airbus moved to take over selected Spirit operations tied to its programmes.
Senior has also recently upgraded its annual profit outlook for the second time in two months, driven by stronger-than-expected aerospace demand. The company confirmed it has postponed the launch of its planned £40 million share buyback programme while takeover discussions continue.
