Milan-based Salini Impregilo S.p.A. has named Goldman Sachs to advise on the possible sale of the $600-million-a-year paving unit of its U.S. subsidiary Lane Construction Corp. The sale would help cut debt and fund expansion in the U.S. infrastructure sector. Now accounting for 30% of group sales, the U.S. is “where we can keep growing,” CEO Pietro Salini told investors and analysts on April 30. The publicly-owned firm also may seek a listing on the New York Stock Exchange.
