Aggregate Industries of the UK has called in Greenhill for advice on a £1.8bn (€2.6bn) takeover approach from Swiss cement group Holcim, advised by Citigroup.

Greenhill has not advised the firm on any of last year's four acquisitions, according to Dealogic, the data provider. Livingstone Guarantee, a UK corporate finance boutique, is the only adviser listed on the deals which totalled $110m.
