It looks like Weir Group's attempt to merge with Finnish rock-crushing major Metso might not be as simple as it hoped.
Oil and gas engineer Weir last week confirmed it was proposing an "all-shares merger" with Metso, but financial blogger Ben Harrington yesterday reported rumours that Weir could be preparing to add a cash element to the offer, amid fears of a rival bid and lukewarm reception of the offer from Metso investors.
Gossip in the City named US mining-equipment specialist Joy Global as a potential rival bidder, as well as General Electric's mining division.
A spokesperson for Weir said its bid remains unchanged, adding: "We're not going to speculate on what we may or may not do in the future."
Metso's spokesperson confirmed the company is still considering Weir's offer and is not engaged in dialogue with the company.
Weir fell 14p to 2,567p.
