The takeover will end on Nov. 11, the investment vehicle of the two investors said on Monday.

The Benetton family and the U.S. fund, who have joined forces through investment vehicle Schema Alfa, aim to take the Italian airport and motorway operator private by the end of this year. They are offering Atlantia's investors 23 euros per share and a proposed dividend of 0.74 euros a share.
