Europe: Holcim's largest stakeholder, Thomas Schmidheiny, wants a better deal for the Holcim's shareholders in its planned merger with Lafarge, according to Swiss Newspaper SonntagsZeitung, which cited people close to Schmidheiny.

The merger with France's Lafarge to create the world's biggest cement company was agreed on 7 April 2015, but analysts have since flagged a potential divergence between the two companies' earnings prospects, raising the possibility of a renegotiation of terms.

SonntagsZeitung said that Holcim board member Schmidheiny, who owns 20.1% of the company according to Thomson Reuters data, sees two possible solutions. One is to weigh the exchange ratio of shares in favour of Holcim investors. Another is a special dividend. The paper also quoted another board member as saying the deal will not work in its current form, which includes each Lafarge share being swapped for one Holcim share.

SonntagsZeitung has also reported that Swiss shareholder group Ethos, which represents around 200 pension funds, is against the deal as it stands and will tell Holcim's board that it will advise members to vote against the merger unless there is a change to the exchange ratio.
