Irish building supplies group CRH (CRH.I) said on Sunday it had agreed to pay 6.5 billion euros for assets Lafarge (LAFP.PA) and Holcim (HOLN.VX) were obliged to sell ahead of their planned merger. CRH, which said it will fund the acquisition with cash, new debt and a 9.99 percent equity placing, beat a consortium led by Blackstone (BX.N), whom several people familiar with the matter told Reuters were also in the running.
