Clarksons Platou Securities is recommending investors pile into the restructured GulfMark Offshore due to a big potential upside.

GulfMark is expected to list its new shares and be open for trading on or about Halloween, after refinancing in early October through a pre-packaged bankruptcy process,the broker said.

The company will be left with net debt of $32m and cash of $68m, said Turner Holm, Clarksons Platou's managing director of equity and credit research.
