(Reuters) - Senior Plc (SNR.L) on Tuesday said ​it had agreed to a takeover ‌proposal from a consortium comprising investment firms Tinicum and Blackstone (BX.N), valuing the British aerospace ​and defence supplier at 1.4 billion ​pounds ($1.85 billion).

The 300 pence per share ⁠cash offer, at a 2.8% premium ​to its last close, will be recommended ​to its shareholders, Senior said.

The firm, which counts Lockheed Martin (LMT.N) among its defence customers, was in ​acquisition talks with several U.S. private ​equity firms.

Shares in Senior, which had a market ‌value ⁠of 1.21 billion pounds as of Tuesday, were trading marginally up as of 1227 GMT.

The Hertfordshire-headquartered firm attributes about 16% ​of its ​revenue ⁠to defence as countries ramp up spending amid global geopolitical ​tensions.

PE firm Arcline walked away from its ​pursuit ⁠of the company last week without specifying the reasons, nearly a month after ⁠the ​firm rejected Advent's 1.14 billion ​pound proposal.
