PE firm Arcline walks away from bid for UK’s Senior as other suitors circle

April 1 (Reuters) – The field of suitors for British aerospace and defence supplier Senior Plc narrowed after ​private equity firm Arcline Investment ‌Management dropped out of buyout talks on Wednesday, though negotiations with other bidders remained ongoing.

Senior, whose shares are only marginally up as ‌of ​0815 GMT, declined to comment ⁠in response to ⁠a Reuters request.

The firm is the latest in a list of UK companies that American PE firms are interested ​in taking over at a time when defence spending has significantly ⁠increased as geopolitical tensions ⁠flare up across the globe.

Senior, ​which caters to customers such as Lockheed ​Martin, attributes 16% of its revenue ‌to defence.

Arcline did not elaborate on why it will not make an offer for the firm.

Under UK takeover ⁠rules, the firm is now prevented from making an approach for Senior for the next ⁠six months, ‌except under some special ⁠circumstances.

Senior, which rejected Advent’s 1.14 ​billion ‌pound ($18.57 billion) proposal in early ​in March, ⁠remains in talks with the PE firm as well as with the Tinicum-Blackstone consortium.
